1. Overview sa Filler Masterbatch Industry ug Product Characteristics

1.1 Kasamtangang Sitwasyon ug Trend sa Pag-uswag sa Filler Masterbatch Industry

Sa bag-ohay nga mga tuig, gimaneho sa paspas nga pag-uswag sa mga industriya sa ubos sama sa packaging, pagtukod, sakyanan, electronics ug adlaw-adlaw nga mga kinahanglanon, ang global filler masterbatch market nagpakita sa usa ka makanunayon nga pagtubo nga uso. Ang Filler masterbatch usa ka klase nga composite nga materyal nga gihimo pinaagi sa pagsagol, pagkatunaw, extruding ug granulating inorganic fillers (sama sa calcium carbonate, talc, barium sulfate, ug uban pa.) uban sa polymer carriers (sama sa polyethylene, polypropylene, polyvinyl chloride, ug uban pa.) ug angay nga mga additives (sama sa mga dispersant, mga compatibility, mga lubricant, ug uban pa.) sa usa ka piho nga proporsiyon. Ang panguna nga gimbuhaton niini mao ang pagpakunhod sa gasto sa produksiyon sa mga produktong plastik samtang gipauswag o gipadayon ang sukaranan nga pasundayag sa mga produktong plastik.

Sumala sa may kalabutan nga estadistika sa datos, milapas na ang global filler masterbatch market size 20 bilyon US dolyares, ug kini gilauman nga magpadayon sa usa ka pagtubo rate sa 6%-9% sa sunod nga mga tuig. Taliwala kanila, calcium carbonate (CaCO3) Ang filler masterbatch mao ang labing kaylap nga gigamit nga tipo sa produkto, accounting alang sa labaw pa kay sa 60% sa kinatibuk-ang filler masterbatch market, gisundan sa talc filler masterbatch, barium sulfate (BaSO4) filler masterbatch ug uban pang espesyal nga filler masterbatch. Ang rehiyon sa Asia-Pacific mao ang pinakadako nga merkado sa produksiyon ug pagkonsumo sa masterbatch sa tibuuk kalibutan, accounting alang sa labaw pa kay sa 50% sa global nga bahin sa merkado, nga nag-una tungod sa paspas nga pag-uswag sa industriya sa pagproseso sa plastik sa China, India ug uban pang mga nasud, ang dako nga panginahanglan alang sa pagkunhod sa gasto ug pagpaayo sa performance sa mga plastik nga produkto, ug ang padayon nga pag-uswag sa kapasidad sa pagsuporta sa industriya.

Ang pag-uswag nga uso sa industriya sa filler masterbatch kasagaran nga gipakita sa upat ka aspeto: una, taas nga performance ug functionalization. Uban sa pag-upgrade sa downstream nga mga kinahanglanon sa produkto nga plastik, Ang filler masterbatch dili na limitado sa pagkunhod sa gasto, apan anam-anam nga nag-uswag padulong sa pagpaandar, sama sa pagpalambo sa rigidity, katig-a, pagbatok sa kainit, weather resistance ug barrier properties sa mga plastic nga produkto, ug pagpalambo sa espesyal nga functional filler masterbatch sama sa flame retardant, antistatic ug antibacterial; ikaduha, taas nga gidaghanon sa pagpuno ug maayo nga dispersibility. Ubos sa premise sa pagsiguro sa performance sa produkto, Ang pagdugang sa gidaghanon sa pagpuno sa dili organikong mga tigpuno mahimo’g makunhuran ang mga gasto sa produksiyon, nga nagbutang sa mas taas nga mga kinahanglanon sa dispersibility sa filler masterbatch-maayo kaayo nga dispersibility makasiguro nga ang filler parehas nga giapod-apod sa plastic matrix, paglikay sa dagway sa puti nga mga spots, itom nga mga spots o agglomeration sa katapusan nga produkto; ikatulo, pagpanalipod sa kinaiyahan ug ubos nga polusyon. Uban ang pagpalig-on sa mga palisiya sa pagpanalipod sa kalikopan sa kalibutan ug pagpauswag sa kahibalo sa pagpanalipod sa kalikopan, Ang mga taghimo sa filler masterbatch anam-anam nga nagsagop sa mga additives ug mga proseso sa produksiyon nga mahigalaon sa kalikopan, pagkunhod sa pagpagawas sa makadaot nga mga butang, ug pagpalambo sa degradable filler masterbatch aron ipahiangay sa pag-uswag sa uso sa berdeng plastik; ikaupat, paniktik ug kahusayan sa mga kagamitan sa produksiyon. Para makasugat sa dinagko, padayon ug taas nga kalidad nga panginahanglan sa produksiyon sa filler masterbatch, ang mga tiggama kanunay nga nagpaila sa mga advanced nga linya sa produksiyon sa granulation ug mga intelihente nga sistema sa pagkontrol, pagpalambo sa produksyon efficiency, pagpakunhod sa gasto sa labor ug pagsiguro sa kalig-on sa kalidad sa produkto.

Batok niini nga background, teknolohiya sa extrusion granulation, isip kinauyokan nga teknolohiya sa filler masterbatch production, nahimong yawe sa pagtino sa kalidad sa filler masterbatch ug ang competitiveness sa mga negosyo. Ang pasundayag sa mga extruder direkta nga makaapekto sa dispersibility, porma sa partikulo, melting index ug uban pang importanteng indicators sa filler masterbatch. Ang among mga propesyonal nga extruder ug mga linya sa produksiyon sa granulation alang sa masterbatch sa filler naugmad agig tubag sa mga kinaiya sa industriya ug panginahanglan sa merkado, nga epektibo nga makasulbad sa mga punto sa kasakit sa pagproseso sa masterbatch sa filler (sama sa dili maayo nga dispersibility, dili parehas nga gidak-on sa partikulo, ubos nga kantidad sa pagpuno, taas nga konsumo sa enerhiya, ug uban pa.) ug pagtabang sa mga negosyo nga makab-ot ang taas nga kalidad ug episyente nga produksiyon.

1.2 Klasipikasyon sa Filler Masterbatch ug ang Panguna nga mga Kinaiya niini

Ang masterbatch sa pagpuno mahimong bahinon sa lainlaing mga lahi sumala sa klase sa tigpuno, carrier resin, natad sa aplikasyon ug kantidad sa pagpuno. Ang matag klase sa filler masterbatch adunay kaugalingon nga talagsaon nga mga kinaiya ug magamit nga mga senaryo. Ang mosunud usa ka detalyado nga pasiuna sa sagad nga klasipikasyon ug kinauyokan nga mga kinaiya sa masterbatch sa filler:

1.2.1 Klasipikasyon sa Type sa Filler:

Kini ang labing kasagaran nga pamaagi sa pagklasipikar alang sa masterbatch sa filler. Sumala sa matang sa dili organikong filler, kini kasagarang bahinon ngadto sa calcium carbonate (CaCO3) filler masterbatch, masterbatch sa talc filler, barium sulfate (BaSO4) filler masterbatch, ug uban pang espesyal nga filler masterbatch (sama sa kaolin filler masterbatch, carbon black filler masterbatch, glass fiber filler masterbatch, ug uban pa.).

  • Calcium Carbonate (CaCO3) Pagpuno sa Masterbatch: Kini ang labing kaylap nga gigamit nga filler masterbatch nga adunay labing ubos nga gasto. Ang filler kasagaran gaan nga calcium carbonate o bug-at nga calcium carbonate. Ang gaan nga calcium carbonate adunay maayo nga gidak-on sa partikulo, maayo nga dispersibility ug taas nga kaputi, nga angay alang sa mga plastik nga produkto nga adunay taas nga mga kinahanglanon sa hitsura ug pagkapino (sama sa mga plastik nga pelikula, mga produkto sa paghulma sa injection); bug-at nga calcium carbonate adunay taas nga katig-a, maayo nga pagsukol sa pagsul-ob ug ubos nga presyo, nga angay alang sa mga plastik nga produkto nga adunay taas nga mga kinahanglanon sa rigidity ug pagkontrol sa gasto (sama sa hinabol nga mga bag, mga bakus sa pagputos, mga tubo, ug uban pa.). Ang masterbatch sa pagpuno sa calcium carbonate dili lamang makapakunhod sa gasto sa produksiyon, apan usab sa pagpalambo sa rigidity, pagbatok sa kainit ug dimensional nga kalig-on sa mga produktong plastik, ug adunay usa ka piho nga lubricating nga epekto, nga makapauswag sa pagproseso sa fluidity sa mga plastik.
  • Talc Filler Masterbatch: Ang filler kay talc powder nga naay layered structure. Ang talc powder adunay maayo nga mekanikal nga mga kabtangan, pagbatok sa kainit ug kalig-on sa kemikal. Ang talc filler masterbatch kasagarang gigamit sa polypropylene (Si PP) plastik nga mga produkto, nga makapauswag pag-ayo sa rigidity, temperatura distorsyon sa kainit ug kusog sa epekto sa mga produkto sa PP, ug kaylap nga gigamit sa mga bahin sa awto, mga kabhang sa gamit sa balay, mga plastik nga tubo ug uban pang mga natad nga nanginahanglan taas nga pasundayag.
  • Barium Sulfate (BaSO4) Pagpuno sa Masterbatch: Ang filler kay barium sulfate powder, nga adunay taas nga kaputi, maayo nga transparency, chemical inertness ug radiation resistance. Barium sulfate filler masterbatch angay alang sa mga plastik nga produkto nga adunay taas nga kinahanglanon sa transparency, kaputi ug kalig-on sa kemikal (sama sa mga plastik nga pelikula, plastik nga mga botelya, medikal nga plastik nga mga produkto, ug uban pa.), ug mahimo usab nga gamiton sa radiation-proof plastic nga mga produkto (sama sa medikal nga kagamitan sa pagpanalipod, Mga accessories sa nuclear power plant, ug uban pa.).

1.2.2 Classification by Carrier Resin:

According to the type of carrier resin used, filler masterbatch can be divided into polyethylene (PE) filler masterbatch, polypropylene (Si PP) filler masterbatch, polyvinyl chloride (PVC) filler masterbatch, polyethylene terephthalate (PET) filler masterbatch, ug uban pa. The selection of carrier resin is mainly determined by the type of downstream plastic products. Pananglitan, PE filler masterbatch is suitable for PE plastic products (sama sa mga plastik nga pelikula, mga bag, mga tubo); PP filler masterbatch is suitable for PP plastic products (sama sa hinabol nga mga bag, injection molding parts, mga piyesa sa awto); PVC filler masterbatch is suitable for PVC plastic products (sama sa PVC nga mga tubo, mga profile, mga palid).

1.2.3 Klasipikasyon pinaagi sa Application Field:

According to the application field of downstream plastic products, filler masterbatch can be divided into film-grade filler masterbatch, injection-grade filler masterbatch, extrusion-grade filler masterbatch, blow molding-grade filler masterbatch, ug uban pa. Film-grade filler masterbatch requires good dispersibility, high fineness and no impurities, to ensure that the blown film has no white spots, black spots or pinholes, ug nagmintinar sa maayong transparency ug katig-a; Ang masterbatch sa filler sa injection-grade nanginahanglan maayo nga pagka-likido ug parehas nga gidak-on sa partikulo, aron ipahiangay sa paspas nga proseso sa paghulma sa pag-injection ug pagsiguro sa hitsura ug katukma sa sukat sa mga produkto sa indeyksiyon; Ang extrusion-grade filler masterbatch nanginahanglan maayo nga thermal stability ug mekanikal nga mga kabtangan, aron ipahiangay sa taas nga temperatura ug taas nga presyur nga proseso sa extrusion sa mga tubo, profile ug uban pang mga produkto.

1.2.4 Klasipikasyon pinaagi sa Gidaghanon sa Pagpuno:

Sumala sa gidaghanon sa pagpuno sa dili organikong mga tigpuno, filler masterbatch mahimong bahinon ngadto sa ubos nga pagpuno masterbatch (kantidad sa pagpuno 30%-50%), medium-filling nga masterbatch (kantidad sa pagpuno 50%-70%) ug high-filling masterbatch (kantidad sa pagpuno 70% ug sa ibabaw). Ang kantidad sa pagpuno gitino sumala sa mga kinahanglanon sa pasundayag sa mga produkto sa ubos ug ang kapasidad sa pagproseso sa mga kagamitan. Ang high-filling masterbatch adunay mas klaro nga epekto sa pagkunhod sa gasto, apan kini adunay mas taas nga mga kinahanglanon sa dispersibility sa mga filler ug ang paghimo sa mga extruders-lamang ang high-performance extruders ang makasiguro sa uniporme nga pagsagol ug pagtunaw sa mga high-filling nga mga materyales., paglikay sa agglomeration ug dili maayo nga pagproseso fluidity.

Angay nga hinumdoman nga ang panguna nga mga indikasyon sa pasundayag sa masterbatch sa filler nag-una nga naglakip sa pagkatibulaag, pagkaparehas sa gidak-on sa partikulo, indeks sa pagtunaw, pagkaputi (alang sa light-colored nga mga produkto) ug pagkaangay sa carrier resin. Taliwala kanila, Ang pagkatibulaag mao ang labing kritikal nga timailhan - ang dili maayo nga pagkatibulaag magdala sa dili patas nga pag-apod-apod sa mga filler sa mga produktong plastik, nga moresulta sa mga depekto sama sa puti nga mga spots, itom nga mga spots, agglomeration ug brittle nga mga produkto, nga seryoso nga makaapekto sa panagway ug performance sa mga plastik nga mga produkto. Busa, ang pagpili sa mga advanced extrusion nga kagamitan ug teknolohiya sa pagproseso sa siyensya hinungdanon aron masiguro ang pagkatibulaag ug kinatibuk-ang kalidad sa masterbatch sa filler.

2. Core nga Teknolohiya sa Pagpuno sa Masterbatch Production: Teknolohiya sa Extrusion Granulation

Ang teknolohiya sa extrusion granulation mao ang kinauyokan nga teknolohiya sa produksiyon sa masterbatch sa filler, nga naghiusa sa pagsagol, pagkatunaw, paggunting, pagkatibulaag ug granulation. Kini adunay mga bentaha sa taas nga kahusayan sa produksiyon, maayo nga kalidad sa produkto, lig-on nga adaptability sa hilaw nga materyales ug halapad nga aplikasyon range. Sa paghimo sa filler masterbatch, Ang teknolohiya sa extrusion granulation nag-una nga gigamit aron mahibal-an ang managsama nga pagkatibulaag sa mga dili organikong filler sa polymer carrier, matunaw ug plasticize ang sagol, ug dayon i-extrude ug granulate aron maporma ang granular filler masterbatch nga adunay parehas nga gidak-on, maayo nga fluidity ug stable nga performance. Ang kalidad sa extrusion granulation direkta nga nagtino sa yawe nga performance indicators sa filler masterbatch, sama sa dispersibility, gidak-on sa partikulo ug indeks sa pagtunaw.

2.1 Mga Kinaiya sa Filler Masterbatch Raw Materials ug Mga Kinahanglanon alang sa Extrusion Equipment

Ang mga hilaw nga materyales sa filler masterbatch nag-una naglakip sa tulo ka bahin: dili organikong mga filler (sama sa CaCO3, talc, BaSO4), mga tigdala sa polimer (sama sa PE, Si PP, PVC) ug mga additives (sama sa mga dispersant, mga compatibility, mga lubricant, mga antioxidant, ug uban pa.). Ang mga kinaiya niining mga hilaw nga materyales lahi kaayo, nga nagbutang sa unahan sa mga espesyal nga kinahanglanon alang sa mga kagamitan sa extrusion:

Una, ang dili organikong mga filler adunay taas nga katig-a, dili maayo nga pagkaangay sa mga polymer carriers, ug dali nga ma-aglomerate. Kadaghanan sa dili organikong mga filler (sama sa CaCO3, talc) mga hydrophilic, samtang ang mga polymer carrier kay hydrophobic, nga mosangpot sa dili maayo nga pagkaangay tali sa mga filler ug carrier. Kung ang pagsagol ug paggunting dili igo, ang mga filler mag-agglomerate, nga dili mahimong parehas nga pagkatag sa carrier, nga miresulta sa dili maayo nga kalidad sa filler masterbatch. Dugang pa, ang taas nga katig-a sa dili organikong mga filler mahimong hinungdan sa grabe nga pagsul-ob sa screw ug barrel sa extruder sa panahon sa proseso sa extrusion, nga nagkinahanglan sa screw ug barrel sa extruder nga adunay hilabihan ka taas nga wear resistance.

Ikaduha, ang sinagol nga filler masterbatch adunay taas nga viscosity ug dili maayo nga pagka-likido. Ang pagdugang sa usa ka dako nga gidaghanon sa dili organikong mga filler makadugang sa viscosity sa sagol, pagpakunhod sa fluidity sa pagproseso, ug nagkinahanglan sa extruder nga adunay lig-on nga conveying kapasidad ug shearing force aron masiguro ang hapsay nga pag-uswag sa pagtunaw, pagsagol ug extrusion.

Ikatulo, pig-ot ang sakup sa temperatura sa pagproseso. Ang lainlaing mga resin sa carrier adunay lainlaing mga punto sa pagtunaw ug kalig-on sa kainit. Pananglitan, ang natunaw nga punto sa PE mao ang 100-130 ℃, ang natunaw nga punto sa PP mao ang 160-170 ℃, ug ang PVC dali nga madunot sa taas nga temperatura (labaw sa 160 ℃). Busa, ang mga kagamitan sa extrusion kinahanglan adunay tukma nga kapasidad sa pagkontrol sa temperatura aron masiguro nga ang sagol hingpit nga natunaw nga wala’y thermal decomposition, ug aron malikayan ang pagkadunot sa mga additives ug ang pagkadaot sa performance sa produkto.

Base sa mga kinaiya sa ibabaw, Ang single-screw extruders dili angay alang sa dako ug taas nga kalidad nga produksyon sa filler masterbatch. Tungod kay ang single-screw extruder adunay usa ka pig-ot nga shear range, kabus nga kapasidad sa pumping ug walay epekto sa paglimpyo sa kaugalingon. Kung giproseso ang high-viscosity ug high-filler mixtures, kini dali nga hinungdan sa pagtipon sa materyal, pagbabag ug dili patas nga pagsagol sa extruder barrel, nga miresulta sa dili maayo nga dispersibility sa filler masterbatch, dili parehas nga gidak-on sa partikulo ug dili lig-on nga kalidad sa produkto. Dugang pa, ang single-screw extruder adunay taas nga konsumo sa enerhiya sa pagproseso sa high-filler nga mga materyales, ug ang tornilyo ug baril grabe nga gisul-ob, nga nagdugang sa gasto sa produksiyon ug gasto sa pagmentinar sa kagamitan sa mga negosyo.

Twin-screw extruders, sa laing bahin, adunay klaro nga mga bentaha sa pagpuno sa masterbatch nga produksiyon ug nahimo nga mainstream nga kagamitan alang sa filler masterbatch extrusion granulation. Ang twin-screw extruders adunay mas lapad nga shear range, mas epektibo nga pumping effect ug self-cleaning effect, nga epektibo nga makasulbad sa mga problema sa dili maayo nga pagkaangay, sayon ​​agglomeration ug dili maayo nga fluidity sa filler masterbatch hilaw nga materyales. Ang intermeshing ug rotating sa twin screws makamugna og kusog nga shear force ug kneading force, nga hingpit nga makaguba sa mga agglomerates sa dili organikong mga filler, himoa nga ang mga filler parehas nga nagkatag sa polymer carrier, ug pagsiguro sa dispersibility ug kalig-on sa produkto. Dugang pa, ang twin-screw extruder adunay maayo nga pagkontrol sa temperatura nga katukma, lig-on nga adaptability sa hilaw nga materyales, ug mahimong mopahiangay sa pagproseso sa lain-laing mga matang, lainlaing kantidad sa pagpuno sa masterbatch sa filler, ug adunay taas nga kahusayan sa produksiyon ug ubos nga konsumo sa enerhiya.

2.2 Prinsipyo sa Pagtrabaho sa Filler Masterbatch Extrusion Granulation

Ang proseso sa extrusion granulation sa filler masterbatch usa ka komplikado nga proseso sa pisikal ug kemikal, nga naglakip sa interaksyon sa daghang mga butang sama sa temperatura, pressure, kusog ug oras sa paggunting. Ang piho nga prinsipyo sa pagtrabaho ug dagan sa proseso mao ang mosunod:

Una, pretreatment sa hilaw nga materyal. Ang hilaw nga materyales sa filler masterbatch (dili organikong mga filler, carrier resin, mga additives) kinahanglan nga pretreated aron masiguro ang kalidad sa katapusan nga produkto. Ang piho nga mga lakang naglakip: 1) Pagpauga nga pagtambal: Dili organikong mga filler (sama sa CaCO3, talc) kasagaran hydrophilic ug adunay usa ka piho nga kantidad sa kaumog. Kung ang sulud sa kaumog taas kaayo, kini makaapekto sa pagsagol nga epekto ug pagkatag sa mga materyales, ug bisan ang hinungdan sa mga bula sa extruded masterbatch. Busa, ang mga filler kinahanglan nga mamala sa usa ka dryer (sama sa usa ka mainit nga hangin dryer, usa ka vacuum dryer) sa pagpakunhod sa kaumog sulod sa ubos 0.5%. 2) Pagdugmok ug pag-ayag: The carrier resin (sama sa PE, Si PP) is crushed into small particles or powder with a particle size of 20-40 mata sa baling, which is conducive to uniform mixing with fillers and additives. Inorganic fillers are also sieved to remove impurities and large particles, ensuring the fineness and uniformity of fillers. 3) Premixing: According to the formula ratio, the dried fillers, carrier resin particles and additives (mga dispersant, mga compatibility, mga lubricant, ug uban pa.) are put into a high-speed mixer for premixing. The mixing speed is generally 800-1200 rpm, and the mixing time is 5-10 minuto. The purpose of premixing is to make the additives evenly adhere to the surface of fillers and carrier resin, improve the compatibility between fillers and carrier, and lay a foundation for subsequent extrusion mixing. The dispersant is a key additive in premixing, which can form a protective film on the surface of the filler, pagpakunhod sa enerhiya sa nawong sa filler, pugngan ang filler gikan sa pag-agglomerating, ug pagpaayo sa dispersibility sa filler sa carrier resin.

Ikaduha, pagpakaon ug paghatod. Ang premixed mixture gipadala ngadto sa feeding hopper sa twin-screw extruder pinaagi sa screw feeder o belt feeder.. Ang katulin sa pagpakaon kinahanglan nga managsama ug lig-on, nga gipares sa screw speed ug extrusion speed sa extruder, aron masiguro nga ang mga materyales mosulod sa extrusion nga lungag nga lig-on ug malikayan ang pagtipon sa materyal o dili igo nga pagpakaon. Ang feeding device sa extruder kasagaran adunay gamit sa frequency conversion speed regulation function, nga maka-adjust sa gikusgon sa pagpakaon sumala sa aktuwal nga sitwasyon sa produksyon.

Ikatulo, pagkatunaw, pagsagol ug paggunting. The materials entering the extrusion cavity of the twin-screw extruder are pushed forward continuously by the rotating screws. The extrusion cavity is composed of a screw and a barrel, ug ang gidaghanon sa extrusion lungag anam-anam nga pagkunhod sa daplin sa axis direksyon. When the screws rotate, the materials are gradually compressed under the action of the screws and the barrel, ug ang presyur sa extrusion nga lungag anam-anam nga motaas (generally 3-15MPa). Sa samang higayon, the materials are subjected to strong shear force and friction force generated by the relative movement between the screws and the barrel, ingon man usab sa taliwala sa mga paglupad sa tornilyo.

The shear force and friction force can fully break the agglomerates of inorganic fillers, make the fillers uniformly dispersed in the melted carrier resin, and promote the fusion and compatibility between the fillers and the carrier. The friction force can also generate a certain amount of heat, which is combined with the external heating of the barrel (electric heating or steam heating) to make the carrier resin gradually melt and plasticize. The barrel of the extruder is usually divided into 3-6 mga seksyon sa pagkontrol sa temperatura (seksyon sa pagpakaon, seksyon sa pagtunaw, seksyon sa pagsagol, homogenizing nga seksyon, ug uban pa.), and the temperature of each section is precisely controlled according to the type of carrier resin and filler. Pananglitan, when processing PE carrier filler masterbatch, the temperature of the feeding section is 80-100℃, the melting section is 120-140℃, the mixing section is 140-150℃, and the homogenizing section is 130-140℃; when processing PP carrier filler masterbatch, the temperature of each section is 20-30℃ higher than that of PE carrier.

Ikaupat, extrusion and shaping. The fully melted, mixed and dispersed material is pushed to the die head of the extruder by the screws. The die head is equipped with multiple die holes (the number and size of die holes are determined according to the particle size of the masterbatch), and the material is extruded from the die holes at a high speed to form continuous strips of uniform thickness. The temperature of the die head is slightly lower than that of the homogenizing section, which can prevent the material from decomposing due to excessive temperature and ensure the shaping effect of the strips.

Ikalima, cooling and cutting. The extruded strips are sent to a cooling device (such as a water tank, an air-cooled conveyor) for rapid cooling. The cooling temperature is generally 20-30℃, and the cooling time is 2-5 minuto. Rapid cooling can make the strips solidify quickly, maintain the shape and size of the strips, and avoid deformation. Human makapabugnaw, the strips are sent to a granulator for cutting. Ang granulator adunay gamit nga rotary knife, nga makaputol sa mga strips ngadto sa granular filler masterbatch nga adunay uniporme nga gidak-on (ang gidak-on sa tipik kasagaran 2-5mm, nga mahimong ipasibo sumala sa panginahanglan sa kustomer). Ang katulin sa rotary knife gipares sa katulin sa pagpadala sa mga gilis aron masiguro nga parehas ang gidak-on sa partikulo sa masterbatch..

Ikaunom, screening ug packaging. Ang giputol nga granular filler masterbatch gipadala sa usa ka vibrating screen alang sa screening, nga makatangtang sa dili kwalipikado nga mga partikulo (ingon nga dako kaayo, gamay ra kaayo o agglomerated nga mga partikulo) ug pagsiguro sa pagkaparehas sa produkto. Ang kwalipikado nga masterbatch dayon ipadala sa usa ka awtomatikong packaging machine alang sa pagputos. Ang mga detalye sa pagputos mahimong ipasibo sumala sa mga panginahanglanon sa kustomer (sama sa 25kg/bag, 50kg/bag), and the packaging should be sealed and moisture-proof to prevent the masterbatch from absorbing moisture and affecting the quality. Pagkahuman sa pagputos, ang mga produkto gitipigan sa usa ka uga, cool ug ventilated nga bodega.

2.3 Key Factors Affecting Filler Masterbatch Extrusion Granulation Effect

The effect of extrusion granulation directly affects the quality of filler masterbatch. There are many factors affecting the granulation effect, nag-una naglakip sa hilaw nga materyal nga mga kinaiya, formula ratio, premixing effect, mga parameter sa extrusion ug istruktura sa ulo sa mamatay. Mastering these key factors and making scientific adjustments can ensure the stability of the granulation effect and the consistency of product quality.

2.3.1 Mga Kinaiya sa Hilaw nga Materyal:

Ang tipo, gidak-on sa partikulo, moisture content and purity of raw materials have a great impact on the granulation effect. Pananglitan, the particle size of inorganic fillers directly affects the dispersibility and fineness of the masterbatch. The finer the particle size of the filler (kasagaran 800-2000 mata sa baling), the better the dispersibility, but the higher the cost and the easier it is to agglomerate; the coarser the particle size, the lower the cost, but the dispersibility is poor, which will affect the appearance and performance of the masterbatch. The moisture content of raw materials (especially fillers) should be controlled below 0.5%; if the moisture content is too high, it will cause bubbles in the masterbatch, affect the density and mechanical properties of the product. The purity of raw materials is also very important; mga hugaw sa hilaw nga materyales (such as stones, metals, abog) will not only affect the quality of the masterbatch, but also wear the screw and barrel of the extruder, and even cause equipment blockage.

2.3.2 Formula Ratio:

The formula ratio of filler masterbatch (the ratio of filler, carrier resin and additives) is the key to determining the performance and cost of the product. The filling amount of the filler should be determined according to the performance requirements of the downstream product and the processing capacity of the equipment. Too high filling amount will lead to poor dispersibility, low toughness and poor processing fluidity of the masterbatch; too low filling amount will reduce the cost reduction effect. The type and dosage of additives also need to be reasonably matched. Pananglitan, the dispersant dosage is generally 1%-3% of the filler dosage; too little dispersant will lead to poor dispersibility of the filler, and too much dispersant will affect the compatibility between the masterbatch and the downstream plastic products, and reduce the mechanical properties of the products. The compatibilizer is used to improve the compatibility between the filler and the carrier resin; kasagaran ang dosis 0.5%-2%, nga makapauswag pag-ayo sa dispersibility ug mekanikal nga mga kabtangan sa masterbatch. Ang lubricant gigamit sa pagpakunhod sa friction tali sa mga materyales ug sa screw, baril ug mamatay nga ulo, pagpalambo sa fluidity sa pagproseso, ug pugngi ang mga materyales nga mopilit sa mga ekipo; kasagaran ang dosis 0.3%-1%.

2.3.3 Epekto sa Premixing:

Ang premixing mao ang pundasyon sa extrusion granulation. Ang pagkaparehas sa premixing direkta nga makaapekto sa dispersibility sa filler sa carrier resin. Kung ang premixing dili patas, ang mga additives dili mahimong parehas nga gisunod sa nawong sa filler ug carrier, nga miresulta sa lokal nga agglomeration sa filler, dili patas nga pagsagol sa mga materyales sa panahon sa extrusion, ug dili maayo nga kalidad sa masterbatch. Aron masiguro ang premixing nga epekto, gikinahanglan nga kontrolon ang katulin sa pagsagol, mixing time and mixing temperature. The mixing speed is generally 800-1200 rpm, the mixing time is 5-10 minuto, and the mixing temperature is controlled at 40-60℃ (appropriate temperature can improve the adhesion of additives and promote uniform mixing).

2.3.4 Mga Parameter sa Extrusion:

Extrusion parameters are the most important factors affecting the granulation effect, nag-una lakip na ang screw speed, temperatura sa extrusion ug presyur sa extrusion.

  • Bilis sa Screw: The screw speed generally ranges from 150 sa 600 rpm. Ang mas taas nga screw speed, mas dako ang shear force ug friction force nga nadawat sa mga materyales, the better the mixing and dispersing effect of the filler, and the higher the production efficiency. Hinuon, kung ang screw speed taas kaayo, ang panahon sa pinuy-anan sa mga materyales sa extrusion lungag mubo ra kaayo, resulting in incomplete melting of the carrier resin, insufficient mixing of the materials, and uneven particle size of the masterbatch; kung ang tulin sa tornilyo ubos kaayo, ang shear force ug friction force dili igo, the filler cannot be fully dispersed, and the production efficiency is low. The screw speed should be adjusted according to the filling amount and type of filler masterbatch—for high-filling masterbatch, a higher screw speed is needed to ensure sufficient shearing and mixing.
  • Temperatura sa Extrusion: The extrusion temperature is divided into multiple sections (seksyon sa pagpakaon, seksyon sa pagtunaw, seksyon sa pagsagol, homogenizing nga seksyon, mamatay ulo nga seksyon), and the temperature of each section needs to be precisely controlled according to the type of carrier resin and filler. Ang temperatura sa seksyon sa pagpakaon mas ubos (slightly higher than the melting point of the carrier resin), nga nag-una sa pagpugong sa mga materyales gikan sa caking ug pagsiguro sa hapsay nga pagpakaon; ang temperatura sa natunaw nga seksyon mao ang medium, which is mainly to promote the melting and plasticization of the carrier resin; ang temperatura sa seksyon sa pagsagol mas taas, nga nag-una sa pagpauswag sa paggunting ug pagsagol nga epekto, and promote the uniform dispersion of the filler; the temperature of the homogenizing section is slightly lower than the mixing section, which is mainly to ensure the uniform temperature and viscosity of the materials, and avoid thermal decomposition; the temperature of the die head section is slightly lower than the homogenizing section, which is to ensure the shaping effect of the strips.
  • Presyon sa Extrusion: The extrusion pressure is generally 3-15MPa. Ang presyur sa extrusion cavity nag-una nga gitino sa compression ratio sa screw, ang die hole size ug ang screw speed. Mas taas ang presyur sa extrusion, the better the mixing and dispersing effect of the materials, and the denser the masterbatch particles. Hinuon, if the pressure is too high, kini makadugang sa konsumo sa enerhiya ug pagsul-ob sa mga ekipo, and even cause the die head to block; kung ang presyur ubos kaayo, the materials cannot be fully compressed and mixed, the masterbatch particles are loose, and the performance is unstable.

2.3.5 Die Head Structure:

Ang die head structure nag-una naglakip sa numero, porma ug gidak-on sa mga die hole. The shape of the die hole determines the cross-sectional shape of the extruded strips (sama sa circular, kuwadrado), and the size of the die hole determines the initial diameter of the strips and the final particle size of the masterbatch. Mas gamay ang gidak-on sa die hole, mas dako ang extrusion pressure, the better the mixing and dispersing effect, apan ang kapasidad sa produksiyon makunhuran; the larger the die hole size, the lower the extrusion pressure, the lower the production efficiency, but the particle size of the masterbatch is larger. Ang gidaghanon sa mga die hole makaapekto sa kapasidad sa produksyon; the more the number of die holes, mas taas ang kapasidad sa produksiyon, apan gikinahanglan aron masiguro nga ang pag-apod-apod sa presyur managsama, so as to avoid uneven thickness of the strips and uneven particle size of the masterbatch.

3. Ang among mga Extruder: Advantages and Product Series for Filler Masterbatch Production

Dugay na kaming nakigbahin sa panukiduki, development and production of high-performance extruders and granulation production lines, and have accumulated rich experience in the field of filler masterbatch processing. According to the characteristics of filler masterbatch raw materials (high hardness, poor compatibility, taas nga viscosity) and processing requirements (good dispersibility, uniform particle size, high filling amount), we have developed a series of twin-screw extruders specially suitable for filler masterbatch production. Our extruders have the advantages of high wear resistance, strong shearing force, tukma nga pagkontrol sa temperatura, stable performance and low operating cost, which can meet the processing needs of various types, lainlaing kantidad sa pagpuno sa masterbatch sa filler (CaCO3, talc, BaSO4, ug uban pa.), and help enterprises improve production efficiency, ensure product quality and reduce production costs.

3.1 Main Advantages of Our Extruders for Filler Masterbatch Production

3.1.1 High Wear Resistance, Long Service Life:

Aiming at the problem that inorganic fillers (sama sa CaCO3, talc) have high hardness and easy to wear the screw and barrel, we adopt high-quality wear-resistant materials and advanced manufacturing technology to ensure the wear resistance of the core components of the extruder. The screw and barrel are made of imported wear-resistant alloy steel (such as 38CrMoAlA), and after nitriding treatment or bimetallic composite treatment, the surface hardness can reach ≥65 HRC, which has extremely strong wear resistance and corrosion resistance, and can effectively resist the wear caused by the friction between the high-hardness filler and the components. This greatly extends the service life of the screw and barrel, reduces the frequency of component replacement, and reduces the maintenance cost of the equipment. Dugang pa, we also provide professional wear detection services for the screw and barrel. Our technical team will regularly detect the wear degree of the screw and barrel for customers, pag-isyu ug detalyadong report sa pagsul-ob, and put forward targeted replacement and maintenance suggestions, ensuring that customers only replace components when necessary, avoiding unnecessary waste.

3.1.2 Strong Shearing and Mixing Capacity, Excellent Dispersibility:

The key to filler masterbatch production is to ensure the uniform dispersion of fillers. Our twin-screw extruders adopt an intermeshing co-rotating twin-screw structure, uban sa usa ka makatarunganon nga screw pitch, lead and compression ratio design. Ang intermeshing ug rotating sa twin screws makamugna og kusog nga shear force ug kneading force, nga hingpit nga makaguba sa mga agglomerates sa dili organikong mga filler, make the fillers uniformly dispersed in the melted carrier resin, and ensure the dispersibility of the masterbatch. The screw is designed with a modular structure, and different screw elements (such as conveying elements, pagsagol sa mga elemento, shearing elements) can be freely combined according to the type and filling amount of filler masterbatch, so as to adjust the shear force and mixing effect, and achieve the best processing effect. Pananglitan, when processing high-filling CaCO3 masterbatch, we can configure more shearing elements to enhance the shearing effect and ensure the uniform dispersion of the filler; when processing talc masterbatch which requires high mixing uniformity, we can configure more mixing elements to improve the mixing effect.

3.1.3 Tukma nga Pagkontrol sa Temperatura, Stable Performance:

Our extruders adopt advanced intelligent temperature control systems, which can realize precise control of the temperature of each section of the barrel and the die head. The temperature control accuracy can reach ±1℃, which can ensure that the carrier resin is fully melted without thermal decomposition, and the additives are not decomposed, ensuring the stability of the product performance. The temperature control system is equipped with a real-time monitoring and alarm function. If the temperature of any section exceeds the set range, ang sistema magpagawas ug alarm prompt sa oras, and even automatically adjust the heating power or shut down the equipment if necessary, aron malikayan ang pagkapakyas sa kagamitan ug mga problema sa kalidad sa produkto. Dugang pa, the extruder is equipped with a high-precision pressure sensor, which can monitor the extrusion pressure in real time. If the pressure is too high or too low, the system will adjust the screw speed or feeding speed automatically, ensuring the stability of the extrusion process.

3.1.4 Lapad nga Application Range, Strong Flexibility:

Our extruder series can adapt to the processing needs of various types of filler masterbatch, including CaCO3 filler masterbatch, masterbatch sa talc filler, BaSO4 filler masterbatch, ug uban pang espesyal nga filler masterbatch. The filling amount can be adjusted from 30% sa 80%, which can meet the different cost and performance requirements of customers. The modular design of the extruder (tornilyo, baril, mamatay ulo, ug uban pa.) makes the replacement of components more convenient and quick. When customers need to adjust the product type or filling amount, they only need to replace the corresponding components, nga walay pag-ilis sa tibuok nga kagamitan, which reduces the cost of equipment transformation and improves the flexibility and adaptability of the equipment. Dugang pa, our extruders can also be matched with different auxiliary equipment (such as high-speed mixers, dryers, coolers, granulators, screening machines, packaging machines) to form a complete automatic granulation production line, realizing continuous production from raw material pretreatment to product packaging.

3.1.5 High Production Efficiency, Low Energy Consumption:

Agricultural plastic products (such as greenhouse films, mulch films, mga tubo sa irigasyon, fertilizer bags) have the characteristics of large dosage, low cost and harsh use environment. Filler masterbatch can effectively reduce the production cost of agricultural plastic products and improve their service life.

  • Greenhouse Films and Mulch Films: These products need to have good transparency, katig-a, weather resistance and anti-aging properties. The filler masterbatch used is mainly light calcium carbonate filler masterbatch or barium sulfate filler masterbatch. Adding 1%-4% of light calcium carbonate filler masterbatch can reduce the cost of the film, improve its toughness and anti-aging properties, and extend the service life of the film; barium sulfate filler masterbatch can improve the transparency and light transmittance of the film, which is conducive to the photosynthesis of crops.
  • Irrigation Pipes and Fertilizer Bags: Irrigation pipes need to have good pressure resistance and wear resistance; fertilizer bags need to have good toughness and wear resistance. The filler masterbatch used is mainly heavy calcium carbonate filler masterbatch or talc filler masterbatch. Adding 5%-10% of heavy calcium carbonate filler masterbatch can improve the pressure resistance and wear resistance of irrigation pipes, reduce the cost; pagdugang 3%-6% of talc filler masterbatch can improve the toughness and wear resistance of fertilizer bags, making them not easy to break during transportation and use.

4.2 Usage Methods of Filler Masterbatch

The correct use of filler masterbatch is crucial to ensure the quality of plastic products and give full play to the performance of the masterbatch. The usage methods of filler masterbatch mainly include mixing ratio, mixing method, processing parameter adjustment and precautions. The specific operation points are as follows:

4.2.1 Determination of Mixing Ratio:

The mixing ratio of filler masterbatch and base plastic (carrier resin of plastic products) is mainly determined by the filling amount of the masterbatch, the performance requirements of the final product and the processing capacity of the equipment. The general mixing ratio range is 1%-20%, and the specific ratio can be adjusted according to the following principles:

  • For plastic products with low performance requirements and high cost control requirements (such as ordinary plastic bags, garbage bags), the mixing ratio can be 5%-20% (using low-to-medium filling calcium carbonate filler masterbatch);
  • For plastic products with medium performance requirements (sama sa mga plastik nga pelikula, ordinary injection molding parts), the mixing ratio can be 2%-8% (using medium filling calcium carbonate, talc or barium sulfate filler masterbatch);
  • For plastic products with high performance requirements (sama sa mga piyesa sa awto, electronic product shells, high-grade films), the mixing ratio can be 1%-5% (using high-filling, high-performance talc, barium sulfate or glass fiber reinforced filler masterbatch);
  • For transparent or semi-transparent plastic products (such as plastic bottles, transparent films), the mixing ratio should be controlled at 1%-3%, and barium sulfate or light calcium carbonate filler masterbatch with fine particle size (sa ibabaw 1250 mata sa baling) should be selected to avoid affecting the transparency of the products.

4.2.2 Mixing Method:

The mixing of filler masterbatch and base plastic should ensure uniformity, so as to avoid local agglomeration of the masterbatch and affect the performance of the final product. The common mixing methods include dry mixing and wet mixing, among which dry mixing is the most widely used in industrial production.

  • Dry Mixing: This method is suitable for most filler masterbatch and base plastic (sama sa PE, Si PP, PVC). The specific steps are: una, dry the base plastic particles and filler masterbatch to remove moisture (the moisture content should be controlled below 0.5%); unya, put the base plastic particles and filler masterbatch into a high-speed mixer according to the determined mixing ratio, and add an appropriate amount of lubricant (if necessary) to mix uniformly. The mixing speed is generally 500-800 rpm, and the mixing time is 3-5 minuto. Human sa pagsagol, the mixture can be directly sent to the extruder or injection molding machine for processing. The advantages of dry mixing are simple operation, taas nga kahusayan, low cost and no pollution to the product.
  • Wet Mixing: This method is suitable for filler masterbatch with poor dispersibility or base plastic with high viscosity (such as PVC paste). The specific steps are: mix the filler masterbatch with an appropriate amount of solvent (such as plasticizer, solvent oil) to form a paste, then add the paste to the base plastic and stir uniformly, and finally remove the solvent through heating or drying. The advantages of wet mixing are good mixing effect and uniform dispersion of the masterbatch; the disadvantages are complex operation, high cost, and easy residual solvent affecting the product quality. Busa, wet mixing is only used in special cases.

4.2.3 Adjustment of Processing Parameters:

When adding filler masterbatch to plastic processing, the processing parameters (sama sa temperatura, pressure, tulin sa screw) need to be properly adjusted according to the type and filling amount of the masterbatch to ensure the smooth progress of processing and the quality of the final product.

  • Temperature Adjustment: The addition of filler masterbatch will increase the viscosity of the mixture, so the processing temperature needs to be appropriately increased by 5-15℃ compared with the processing temperature of pure base plastic. Pananglitan, when processing PE plastic with calcium carbonate filler masterbatch, the processing temperature can be increased by 5-10℃; when processing PP plastic with talc filler masterbatch, the processing temperature can be increased by 10-15℃. It should be noted that the temperature should not be too high to avoid thermal decomposition of the base plastic and additives.
  • Pressure Adjustment: The addition of filler masterbatch will increase the resistance during processing, so the processing pressure (presyur sa extrusion, injection pressure) needs to be appropriately increased by 10%-20%. Pananglitan, when extruding plastic pipes with filler masterbatch, the extrusion pressure can be increased by 10%-15% to ensure the compactness and dimensional accuracy of the pipes; when injecting plastic parts with filler masterbatch, the injection pressure can be increased by 15%-20% to avoid defects such as insufficient filling and shrinkage.
  • Screw Speed Adjustment: The screw speed should be adjusted according to the type and filling amount of the masterbatch. For high-filling masterbatch or masterbatch with poor dispersibility, the screw speed can be appropriately increased by 10%-15% to enhance the shear force and mixing effect, ensuring the uniform dispersion of the filler; for low-filling masterbatch or masterbatch with good dispersibility, the screw speed can be kept unchanged or slightly reduced to reduce energy consumption and wear of equipment.

4.2.4 Precautions for Use:

In the process of using filler masterbatch, the following precautions should be paid attention to to avoid affecting the processing effect and product quality:

  • Moisture Prevention: Pagpuno masterbatch (especially calcium carbonate, talc masterbatch) is easy to absorb moisture, which will cause bubbles, pinholes and other defects in the final product. Busa, the masterbatch should be stored in a dry, cool ug ventilated nga bodega, and should be dried before use (the drying temperature is 80-100℃, ug ang panahon sa pagpauga mao 2-4 mga oras).
  • Pagkaangay: The carrier resin of the filler masterbatch should be consistent with or compatible with the base plastic of the product. Pananglitan, PE filler masterbatch should be used with PE base plastic, and PP filler masterbatch should be used with PP base plastic. If the carrier resin is incompatible with the base plastic, it will affect the compatibility between the masterbatch and the base plastic, resulting in poor dispersibility and reduced product performance.
  • Uniform Mixing: The filler masterbatch and base plastic must be mixed uniformly. If the mixing is uneven, local agglomeration of the masterbatch will occur, nga moresulta sa mga depekto sama sa puti nga mga spots, black spots and agglomeration in the product, affecting the appearance and performance of the product.
  • Dosage Control: The dosage of filler masterbatch should not exceed the maximum filling amount applicable to the equipment and product performance. Excessive dosage will lead to poor dispersibility, low toughness, poor processing fluidity and other problems of the product; insufficient dosage will not achieve the effect of cost reduction and performance improvement.
  • Storage Period: The filler masterbatch has a certain storage period (kasagaran 6-12 mga bulan). If the storage period is exceeded, the masterbatch may absorb moisture, agglomerate or the performance of additives may degrade, affecting the use effect. Busa, the masterbatch should be used within the storage period.
