1. Overview of Filler Masterbatch Industry and Product Characteristics

1.1 Current Situation and Development Trend of Filler Masterbatch Industry

In recent years, driven by the rapid development of downstream industries such as packaging, dhismo, baabuur, electronics and daily necessities, the global filler masterbatch market has shown a steady growth trend. Filler masterbatch is a kind of composite material which is made by mixing, dhalaalid, extruding and granulating inorganic fillers (such as calcium carbonate, talc, barium sulfate, iwm.) with polymer carriers (such as polyethylene, polypropylene, polyvinyl chloride, iwm.) and appropriate additives (such as dispersants, waafaqsan, saliidaha, iwm.) in a certain proportion. Shaqadeeda asaasiga ah waa in la yareeyo kharashka wax soo saarka ee alaabta caaga ah iyada oo la hagaajinayo ama la ilaalinayo waxqabadka aasaasiga ah ee alaabta caagga ah.

Marka loo eego tirakoobyada xogta ku habboon, cabbirka suuqa Masterbatch filler-ka adduunka ayaa dhaaftay 20 bilyan oo doolarka Mareykanka ah, waxaana la filayaa in la joogteeyo heerka kobaca ee 6%-9% dhowrka sano ee soo socda. Waxaa ka mid ah, carbonate calcium (CaCO3) Filler Masterbatch waa nooca ugu badan ee la isticmaalo, xisaabinta in ka badan 60% wadarta guud ee buuxinta suuqa masterbatch, oo ay ku xigto talc filler masterbatch, barium sulfate (BaSO4) Filler Masterbatch iyo kuwa kale ee buuxinta gaarka ah. Gobolka Aasiya-Pacific waa suuqa wax soo saarka iyo wax soo saarka ugu weyn adduunka, xisaabinta in ka badan 50% ee saamiga suuqa caalamiga ah, taas oo inta badan sabab u ah horumarka degdega ah ee warshadaha wax soo saarka caaga ah ee Shiinaha, Hindiya iyo dalal kale, Baahida weyn ee dhimista kharashka iyo hagaajinta waxqabadka alaabta caaga ah, iyo horumarinta joogtada ah ee awoodda taageerada warshadaha.

Isbeddelka horumarineed ee warshadaha buuxinta masterbatch waxa ay inta badan ka muuqataa afar dhinac: marka hore, waxqabadka sare iyo shaqeynta. Iyada oo la cusboonaysiinayo shuruudaha badeecada caagga ah ee hoose, Filler Masterbatch hadda kuma koobna dhimista kharashka, laakiin si tartiib tartiib ah ayey u horumaraysaa xagga shaqaynta, sida hagaajinta qallafsanaanta, adkaanshaha, caabbinta kulaylka, iska caabinta cimilada iyo sifooyinka xannibaadaha alaabta caagga ah, iyo horumarinta masterbatches filler functional gaar ah sida olol retardant, antistatic iyo bakteeriyada; labaad, xaddi buuxa oo badan iyo kala firdhisanaan wanaagsan. Iyadoo la raacayo aasaaska hubinta waxqabadka alaabta, kordhinta tirada buuxinta ee buuxinta aan organic ahayn waxay sii yarayn kartaa kharashka wax soo saarka, which puts higher requirements on the dispersibility of filler masterbatch—excellent dispersibility can ensure that the filler is evenly distributed in the plastic matrix, avoiding the appearance of white spots, black spots or agglomeration in the final product; saddexaad, environmental protection and low pollution. Iyadoo la xoojinayo siyaasadaha ilaalinta deegaanka ee caalamiga ah iyo wanaajinta wacyiga ilaalinta deegaanka, filler masterbatch manufacturers are gradually adopting environmentally friendly additives and production processes, reducing the emission of harmful substances, and developing degradable filler masterbatch to adapt to the development trend of green plastics; afraad, intelligence and efficiency of production equipment. In order to meet the large-scale, continuous and high-quality production needs of filler masterbatch, manufacturers are constantly introducing advanced granulation production lines and intelligent control systems, hagaajinta wax-soo-saarka, dhimista kharashka shaqada iyo hubinta xasilloonida tayada alaabta.

Ka soo horjeeda asalkan, technology granulation extrusion, sida tignoolajiyada udub-dhexaadka u ah wax soo saarka masterbatch filler, waxay noqotay furaha lagu go'aamiyo tayada filler masterbatch iyo tartanka ganacsiyada. Waxqabadka extruders ayaa si toos ah u saameeya kala firdhinta, qaabka qayb, tusaha dhalaalka iyo tilmaamayaasha kale ee muhiimka ah ee buuxinta masterbatch. Extruders-yadayada xirfadleyda ah iyo khadadka wax-soo-saarka granulation ee buuxinta Masterbatch waxaa loo sameeyay iyadoo laga jawaabayo sifooyinka warshadaha iyo baahida suuqa, kaas oo si wax ku ool ah u xalin kara dhibcooyinka xanuunka ee farsamaynta masterbatch filler (sida kala daadsanaan liidata, cabbirka walxaha aan sinnayn, qadar yar oo buuxin ah, isticmaalka tamarta sare, iwm.) waxayna ka caawiyaan ganacsiyada inay gaaraan wax soo saar tayo sare leh oo hufan.

1.2 Kala soocida Filler Masterbatch iyo Astaamihiisa Muhiimka ah

Filler Masterbatch waxaa loo qaybin karaa noocyo kala duwan iyadoo loo eegayo nooca buuxinta, xabagta side, goobta codsiga iyo tirada buuxinta. Nooc kasta oo buuxinta Masterbatch wuxuu leeyahay sifooyin u gaar ah iyo xaalado lagu dabaqi karo. Kuwa soo socdaa waa horudhac tafatiran oo ku saabsan kala soocida guud iyo sifooyinka asaasiga ah ee filler masterbatch:

1.2.1 Kala-saarista Nooca Filler:

Tani waa habka ugu caansan ee kala soocida filler masterbatch. Marka loo eego nooca buuxinta inorganic, waxa inta badan loo qaybin karaa kaalshiyam carbonate (CaCO3) buuxinta masterbatch, talc filler masterbatch, barium sulfate (BaSO4) buuxinta masterbatch, iyo kuwo kale oo gaar ah oo buuxinaya masterbatches (sida kaolin filler masterbatch, buuxinta kaarboon madow masterbatch, Fiber-fiber filler masterbatch, iwm.).

• Calcium Carbonate (CaCO3) Filler Masterbatch: Waa masterbatch-ka ugu ballaadhan ee la isticmaalo oo leh qiimaha ugu hooseeya. Buuxiyaha inta badan waa kaalshiyam carbonate fudud ama kaalshiyam carbonate culus. Kaarboonaydh yar oo kalsiyum ah ayaa leh cabbirka qayb yar, kala daadsanaan wanaagsan iyo caddaan sare, kaas oo ku habboon alaabooyinka caaga ah oo leh shuruudo sare oo muuqaal iyo ganaax ah (sida filimada caaga ah, alaabta qaabaynta irbado); Kaarboonka calcium culus ayaa leh engegnaan badan, iska caabin xidhid wanaagsan iyo qiimo jaban, kaas oo ku habboon badeecooyinka caagga ah oo leh shuruudo sare oo adag iyo xakamaynta kharashka (sida bacaha tolmada leh, suunka baakadaha, tuubooyinka, iwm.). Mastarbatch-ka-buuxiyaha kaarboon-caasium ma yarayn karo oo keliya kharashaadka wax-soo-saarka, laakiin sidoo kale hagaajin qallafsanaanta, caabbinta kulaylka iyo xasilloonida cabbirka alaabta caagga ah, oo waxay leedahay saameyn saliideed gaar ah, kaas oo wanaajin kara dareeraha ka baaraandegga caagadaha.
• Talc Filler Masterbatch: The filler is talc powder with layered structure. Talc powder has good mechanical properties, heat resistance and chemical stability. Talc filler masterbatch is mainly used in polypropylene (PP) plastic products, which can significantly improve the rigidity, heat distortion temperature and impact strength of PP products, waxaana si weyn loogu isticmaalaa qaybaha baabuurta, qolofyada qalabka guriga, plastic pipes and other fields that require high performance.
• Barium Sulfate (BaSO4) Filler Masterbatch: The filler is barium sulfate powder, which has high whiteness, good transparency, chemical inertness and radiation resistance. Barium sulfate filler masterbatch is suitable for plastic products with high requirements on transparency, whiteness and chemical stability (sida filimada caaga ah, plastic bottles, medical plastic products, iwm.), and can also be used in radiation-proof plastic products (such as medical protective equipment, nuclear power plant accessories, iwm.).

1.2.2 Kala soocida xabagta side:

Marka loo eego nooca xabagta side ee la isticmaalay, Filler Masterbatch waxaa loo qaybin karaa polyetylen (PE) buuxinta masterbatch, polypropylene (PP) buuxinta masterbatch, polyvinyl chloride (PVC) buuxinta masterbatch, terephthalate polyetylen (PET) buuxinta masterbatch, iwm. Xulashada xabagta side waxaa inta badan lagu go'aamiyaa nooca badeecooyinka balaastikada ah ee hoose. Tusaale ahaan, PE filler masterbatch waxay ku habboon tahay alaabada balaastikada PE (sida filimada caaga ah, bacaha, tuubooyinka); PP Filler Masterbatch waxay ku habboon tahay alaabada balaastiigga ah ee PP (sida bacaha tolmada leh, qaybo qaabaynta irbado, qaybaha baabuurta); Filler PVC Masterbatch waxay ku habboon tahay alaabada caagga ah ee PVC (sida tuubooyinka PVC, profiles, go'yaal).

1.2.3 Kala soocida Goobta Codsiga:

Marka loo eego goobta codsiga ee alaabta caagga ah ee hoose, Filler Masterbatch waxa loo qaybin karaa heer-filim buuxinta Masterbatch, duri-fasalka buuxinta masterbatch, Filler-fasalka extrusion masterbatch, dharbaaxo qaabaynta-fasalka buuxinta Masterbatch, iwm. Buuxiyaha fasalka-filimka Masterbatch wuxuu u baahan yahay kala firdhisanaan wanaagsan, ganaax sare oo aan wasakh lahayn, si loo hubiyo in filimka la afuufay uusan lahayn baro cadcad, black spots or pinholes, and maintains good transparency and toughness; injection-grade filler masterbatch requires good fluidity and uniform particle size, to adapt to the rapid injection molding process and ensure the appearance and dimensional accuracy of injection products; extrusion-grade filler masterbatch requires good thermal stability and mechanical properties, to adapt to the high-temperature and high-pressure extrusion process of pipes, profiles and other products.

1.2.4 Classification by Filling Amount:

According to the filling amount of inorganic fillers, filler masterbatch can be divided into low-filling masterbatch (qaddarka buuxinta 30%-50%), medium-filling masterbatch (qaddarka buuxinta 50%-70%) and high-filling masterbatch (qaddarka buuxinta 70% and above). The filling amount is determined according to the performance requirements of downstream products and the processing capacity of equipment. High-filling masterbatch has more obvious cost reduction effect, but it has higher requirements on the dispersibility of fillers and the performance of extruders—only high-performance extruders can ensure the uniform mixing and melting of high-filling materials, avoiding agglomeration and poor processing fluidity.

It is worth noting that the core performance indicators of filler masterbatch mainly include dispersibility, particle size uniformity, melting index, whiteness (for light-colored products) and compatibility with carrier resin. Waxaa ka mid ah, dispersibility is the most critical indicator—poor dispersibility will lead to uneven distribution of fillers in plastic products, resulting in defects such as white spots, black spots, agglomeration and brittle products, which seriously affect the appearance and performance of plastic products. Sidaa darteed, the selection of advanced extrusion equipment and scientific processing technology is crucial to ensure the dispersibility and overall quality of filler masterbatch.

2. Core Technology of Filler Masterbatch Production: Extrusion Granulation Technology

Extrusion granulation technology is the core technology of filler masterbatch production, which integrates mixing, dhalaalid, shearing, dispersion and granulation. It has the advantages of high production efficiency, good product quality, strong adaptability to raw materials and wide application range. In the production of filler masterbatch, extrusion granulation technology is mainly used to realize the uniform dispersion of inorganic fillers in the polymer carrier, melt and plasticize the mixture, and then extrude and granulate to form granular filler masterbatch with uniform size, good fluidity and stable performance. The quality of extrusion granulation directly determines the key performance indicators of filler masterbatch, such as dispersibility, particle size and melting index.

2.1 Characteristics of Filler Masterbatch Raw Materials and Requirements for Extrusion Equipment

The raw materials of filler masterbatch mainly include three parts: inorganic fillers (such as CaCO3, talc, BaSO4), polymer carriers (such as PE, PP, PVC) and additives (such as dispersants, waafaqsan, saliidaha, antioxidants, iwm.). The characteristics of these raw materials are quite different, which puts forward special requirements for extrusion equipment:

Marka hore, the inorganic fillers have high hardness, poor compatibility with polymer carriers, and are easy to agglomerate. Most inorganic fillers (such as CaCO3, talc) are hydrophilic, while polymer carriers are hydrophobic, which leads to poor compatibility between fillers and carriers. If the mixing and shearing are insufficient, the fillers will agglomerate, which cannot be uniformly dispersed in the carrier, resulting in poor quality of filler masterbatch. In addition, the high hardness of inorganic fillers will cause serious wear to the screw and barrel of the extruder during the extrusion process, which requires the screw and barrel of the extruder to have extremely high wear resistance.

Labaad, the mixture of filler masterbatch has high viscosity and poor fluidity. The addition of a large number of inorganic fillers will significantly increase the viscosity of the mixture, reduce the processing fluidity, and require the extruder to have strong conveying capacity and shearing force to ensure the smooth progress of melting, mixing and extrusion.

Saddexaad, the processing temperature range is narrow. Different carrier resins have different melting points and thermal stability. Tusaale ahaan, the melting point of PE is 100-130℃, the melting point of PP is 160-170℃, and PVC is easy to decompose at high temperatures (above 160℃). Sidaa darteed, the extrusion equipment needs to have precise temperature control capacity to ensure that the mixture is fully melted without thermal decomposition, and to avoid the decomposition of additives and the deterioration of product performance.

Based on the above characteristics, single-screw extruders are not suitable for large-scale and high-quality production of filler masterbatch. Because the single-screw extruder has a narrow shear range, poor pumping capacity and no self-cleaning effect. When processing high-viscosity and high-filler mixtures, it is easy to cause material accumulation, blockage and uneven mixing in the extruder barrel, resulting in poor dispersibility of filler masterbatch, uneven particle size and unstable product quality. In addition, the single-screw extruder has high energy consumption when processing high-filler materials, and the screw and barrel are severely worn, which increases the production cost and equipment maintenance cost of enterprises.

Twin-screw extruders, on the other hand, have obvious advantages in filler masterbatch production and have become the mainstream equipment for filler masterbatch extrusion granulation. Twin-screw extruders have a wider shear range, more effective pumping effect and self-cleaning effect, which can effectively solve the problems of poor compatibility, easy agglomeration and poor fluidity of filler masterbatch raw materials. Is-dhex-galka iyo wareegitaanka furayaasha mataanaha ah waxay dhalin karaan xoog xiirid xoog leh iyo xoog cajiin, which can fully break the agglomerates of inorganic fillers, ka dhig kuwa wax buuxiya si isku mid ah ugu kala firdhiyaan sidaha polymerka, iyo in la hubiyo kala firdhinta iyo xasiloonida alaabta. In addition, extruder-ga mataanaha ah ayaa leh saxnaanta xakamaynta heerkulka wanaagsan, laqabsiga xooggan ee alaabta ceeriin, oo la qabsan kara habaynta noocyada kala duwan, xaddi buuxinta kala duwan ee Masterbatch filler, oo leh wax-soo-saar sare iyo isticmaalka tamarta hooseeya.

2.2 Mabaadi'da Shaqada ee Filler Masterbatch Extrusion Granulation

Habka granulation extrusion ee filler masterbatch waa nidaam adag oo jireed iyo kiimiko, kaas oo ku lug leh isdhexgalka arrimo badan sida heerkulka, cadaadis, xoog xiirid iyo waqti. Mabda'a shaqada gaarka ah iyo socodka geedi socodka waa sida soo socota:

Marka hore, pretreatment alaabta ceeriin. Qalabka ceeriin ee filler masterbatch (inorganic fillers, xabagta side, wax lagu daro) waxay u baahan yihiin in horay loo sii daaweeyaa si loo hubiyo tayada badeecada ugu dambeysa. The specific steps include: 1) Drying treatment: Inorganic fillers (such as CaCO3, talc) are usually hydrophilic and contain a certain amount of moisture. If the moisture content is too high, it will affect the mixing effect and dispersibility of the materials, and even cause bubbles in the extruded masterbatch. Sidaa darteed, the fillers need to be dried in a dryer (such as a hot air dryer, a vacuum dryer) to reduce the moisture content to below 0.5%. 2) Crushing and sieving: The carrier resin (such as PE, PP) is crushed into small particles or powder with a particle size of 20-40 mesh, 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 (dispersants, waafaqsan, saliidaha, iwm.) waxaa lagu ridaa qase-xawaaraha sareeyo si loogu diyaariyo. Xawaaraha isku dhafka ah waa guud ahaan 800-1200 rpm, iyo wakhtiga isku darka waa 5-10 daqiiqado. Ujeedada isku darka hore waa in lagu daro si siman ugu dheggan dusha sare ee buuxinyaasha iyo xabagta qaadaha, wanaaji iswaafajinta udhaxeeya buuxinayaasha iyo sideyaasha, oo aas aas u ah isku darka extrusion ee xiga. Kala firdhiyahu waa wax lagu daro muhimka ah ee premixing, kaas oo samayn kara filim difaac ah oo ku yaal dusha sare ee buuxinta, yaree tamarta dusha sare ee buuxinta, ka ilaali buuxinta inuu kordho, iyo in la hagaajiyo kala firdhisanaanta shayeeyaha ee xabagta qaadaha.

Labaad, quudinta iyo gudbinta. Isku darka la isku daray waxaa loo diraa hopper-ka quudinta ee twin-screw extruder iyada oo la sii marinayo feedhaha ama suunka quudiyaha. Xawaaraha quudintu wuxuu u baahan yahay inuu ahaado mid isku mid ah oo deggan, kaas oo u dhigma xawaaraha isbiirsaday iyo xawaaraha kaxaynta, si loo hubiyo in walxuhu u galaan godka ka soo baxa si degan oo ay uga fogaadaan ururinta alaabta ama quudinta aan ku filnayn. Aaladda quudinta ee fidiyaha ayaa sida caadiga ah ku qalabaysan habaynta xawaaraha beddelka soo noqnoqda, kaas oo hagaajin kara xawaaraha quudinta iyadoo loo eegayo xaaladda dhabta ah ee wax soo saarka.

Saddexaad, dhalaalid, isku dhafka iyo xiirid. Alaabta soo gasha godka extrusion ee fuqarada mataanaha ah waxaa hore u sii riixaya iskoorada wareega. Godka ka soo baxa wuxuu ka kooban yahay fur iyo foosto, iyo mugga daloolka extrusion ayaa si tartiib tartiib ah hoos ugu dhacaya jihada dhidibka. Marka boolalku wareegaan, Qalabka si tartiib tartiib ah ayaa loo cadaadiyaa iyadoo la raacayo ficilka boolal iyo foosto, iyo cadaadiska godka extrusion si tartiib tartiib ah u kordho (guud ahaan 3-15MPa). Isla markaana, Alaabada waxaa lagu sakhiray xoog xiirid xoog leh iyo xoog is jiid jiid ka dhashay dhaqdhaqaaqa qaraabada ah ee u dhexeeya boolal iyo foosto, iyo sidoo kale inta u dhaxaysa duullimaadyada wareegyada.

Xoogga xiirta iyo xoogga is jiid-jiidka waxay si buuxda u jebin karaan aglomerates ee buuxinyaasha aan noolaha ahayn, ka dhig kuwa wax buuxiya si isku mid ah ugu kala firdhiyaan xabagta sidaha dhalaalay, iyo kor u qaadida fiyuuska iyo iswaafajinta ka dhexeeya buuxinyaasha iyo sideyaasha. Xoogga is jiid jiidku wuxuu kaloo dhalin karaa xaddi kuleyl ah, 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 temperature control sections (feeding section, melting section, mixing section, homogenizing section, iwm.), and the temperature of each section is precisely controlled according to the type of carrier resin and filler. Tusaale ahaan, 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.

Afaraad, extrusion and shaping. Si buuxda u dhalaalay, Walxaha isku dhafan iyo kuwa kala firdhiyey ayaa lagu riixaa madaxa dhinta ee kaxeeyaha by boolal. 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. Heerkulka madaxa dhimashadu wax yar ayuu ka hooseeyaa kan qaybta isku midka ah, which can prevent the material from decomposing due to excessive temperature and ensure the shaping effect of the strips.

Fifth, 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 daqiiqado. Rapid cooling can make the strips solidify quickly, maintain the shape and size of the strips, and avoid deformation. After cooling, the strips are sent to a granulator for cutting. The granulator is equipped with a rotary knife, which can cut the strips into granular filler masterbatch with uniform size (the particle size is generally 2-5mm, which can be adjusted according to customer needs). The speed of the rotary knife is matched with the conveying speed of the strips to ensure that the particle size of the masterbatch is uniform.

Sixth, screening and packaging. The cut granular filler masterbatch is sent to a vibrating screen for screening, which can remove unqualified particles (such as too large, too small or agglomerated particles) and ensure the uniformity of the product. The qualified masterbatch is then sent to an automatic packaging machine for packaging. The packaging specifications can be adjusted according to customer needs (such as 25kg/bag, 50kg/bag), baakooyinkana waa in la xidhaa oo aan huurka lahayn si looga hortago in masterbatch-ka uu nuugo qoyaanka oo uu saameeyo tayada. Baakadaha ka dib, alaabta waxaa lagu kaydiyaa meel qalalan, bakhaar qabow oo hawo leh.

2.3 Qodobbada Muhiimka ah ee Saamaynta Filler Masterbatch Extrusion Extrusion Saamaynta

Saamaynta granulation extrusion si toos ah u saameeya tayada filler masterbatch. Waxaa jira arrimo badan oo saameeya saamaynta granulation, inta badan ay ku jiraan sifooyinka alaabta ceeriin, saamiga formula, saamaynta premixing, xuduudaha extrusion iyo dhinta qaab-dhismeedka madaxa. Hagaajinta arrimahan muhiimka ah iyo samaynta hagaajinta sayniska waxay xaqiijin kartaa xasilloonida saameynta granulation iyo joogtaynta tayada alaabta.

2.3.1 Astaamaha Qalabka Ceyriinka:

Nooca, cabbirka walxaha, moisture content and purity of raw materials have a great impact on the granulation effect. Tusaale ahaan, the particle size of inorganic fillers directly affects the dispersibility and fineness of the masterbatch. The finer the particle size of the filler (generally 800-2000 mesh), 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. Nadiifinta alaabta ceeriin sidoo kale waa mid aad muhiim u ah; wasakhda alaabta ceeriin (such as stones, metals, siigada) will not only affect the quality of the masterbatch, laakiin sidoo kale xidho furka iyo foosto ee daba-dheeraha, oo xitaa sababa xannibaadda qalabka.

2.3.2 Saamiga Formula:

Saamiga qaacidada ee filler masterbatch (saamiga buuxinta, xabagta xanbaarsan iyo waxyaabaha lagu daro) waa furaha lagu go'aaminayo waxqabadka iyo qiimaha alaabta. Qadarka buuxinta buuxinta waa in lagu go'aamiyaa iyadoo loo eegayo shuruudaha waxqabadka ee alaabta hoose iyo awoodda farsamaynta qalabka. Qadarka buuxinta aadka u sarreeya waxay u horseedi doontaa kala firdhis xumo, adkaanta hoose iyo dareere ka shaqaynta liidata ee masterbatch; Qadarka buuxinta aadka u hooseeya waxay yaraynaysaa saamaynta dhimista kharashka. Nooca iyo qiyaasta waxyaabaha lagu daro waxay sidoo kale u baahan yihiin in si macquul ah la isku waafajiyo. Tusaale ahaan, qiyaasta kala firdhiyaa waa guud ahaan 1%-3% ee qiyaasta buuxinta; Kala firdhis aad u yar waxay u horseedi doontaa kala firdhisanaan liidata buuxinta, iyo kala firdhinta badan waxay saamaynaysaa iswaafajinta udhaxaysa masterbatch iyo alaabta caaga ah ee hoose, waxayna yareeyaan sifooyinka farsamada ee alaabta. Ku-habeeyaha waxa loo isticmaalaa in lagu wanaajiyo is-waafajinta u dhexeeya buuxinta iyo resinka qaadaha; qiyaasta waa guud ahaan 0.5%-2%, kaas oo si weyn u wanaajin kara kala firdhinta iyo sifooyinka farsamada ee masterbatch. Saliidaha waxaa loo isticmaalaa in lagu dhimo khilaafka u dhexeeya alaabta iyo furka, foosto iyo madaxa dhiman, hagaajinta dheecaanka ka baaraandegidda, kana ilaali alaabta inay ku dhegganaadaan qalabka; qiyaasta waa guud ahaan 0.3%-1%.

2.3.3 Saamaynta Premixing:

Premixing waa aasaaska granulation extrusion. Labbiska hor-mixinta waxay si toos ah u saamaysaa kala firidhsanaanta buuxiyaha ku jira resinka side. Haddii premixingku aanu sinnayn, Waxyaabaha lagu daro si isku mid ah looguma dhejin karo dusha sare ee buuxinta iyo qaadiyaha, taas oo keentay in ay gudaha u galaan faytarka, isku darka aan sinnayn ee alaabta inta lagu jiro extrusion, iyo tayada liidata ee masterbatch. Si loo hubiyo saamaynta premixing, waa lagama maarmaan in la xakameeyo xawaaraha isku dhafka, waqtiga isku dhafka iyo heerkulka isku dhafka. Xawaaraha isku dhafka ah waa guud ahaan 800-1200 rpm, waqtiga isku darka waa 5-10 daqiiqado, and the mixing temperature is controlled at 40-60℃ (appropriate temperature can improve the adhesion of additives and promote uniform mixing).

2.3.4 Extrusion Parameters:

Extrusion parameters are the most important factors affecting the granulation effect, mainly including screw speed, extrusion temperature and extrusion pressure.

• Xawaaraha isku dubaridka: The screw speed generally ranges from 150 ku 600 rpm. The higher the screw speed, the greater the shear force and friction force received by the materials, the better the mixing and dispersing effect of the filler, and the higher the production efficiency. Si kastaba ha ahaatee, if the screw speed is too high, the residence time of the materials in the extrusion cavity is too short, resulting in incomplete melting of the carrier resin, insufficient mixing of the materials, and uneven particle size of the masterbatch; haddii xawaaruhu aad u yar yahay, xoog-xiirid iyo xoog is jiid-jiidku kuma filna, buuxinta si buuxda looma kala firdhi karo, waxtarka wax-soo-saarkuna wuu hooseeyaa. Xawaaraha furka waa in lagu hagaajiyaa iyadoo loo eegayo tirada buuxinta iyo nooca buuxinta masterbatch-ka buuxinta sare ee Masterbatch, xawaare sare oo xawli ah ayaa loo baahan yahay si loo hubiyo xiirid ku filan iyo isku dhafka.
• Heerkulka ka soo baxa: Heerkulka extrusion wuxuu u qaybsan yahay qaybo badan (feeding section, melting section, mixing section, homogenizing section, dhiman madaxa qaybta), iyo heerkulka qayb kasta wuxuu u baahan yahay in si sax ah loo xakameeyo iyadoo loo eegayo nooca xabagta iyo buuxinta. Heerkulka qaybta quudinta ayaa hooseeya (waxyar ka sarreeya barta dhalaalaysa ee xabagta sidaha), Kaas oo inta badan ah in laga ilaaliyo agabka in ay dubtaan iyo in la hubiyo quudin siman; heerkulka qaybta dhalaalidu waa dhexdhexaad, Kaas oo inta badan ah in kor loo qaado dhalaalka iyo balaastigga xabkaha; heerkulka qaybta isku dhafka ayaa sarreeya, Kaas oo inta badan kor loogu qaado xiirta iyo saamaynta isku dhafka ah, iyo kor u qaadida kala firdhinta labbiska ee buuxinta; heerkulka qaybta homogenizing ayaa wax yar ka hooseeya qaybta isku dhafka, taas oo inta badan ah in la hubiyo heerkulka isku midka ah iyo viscosity ee alaabta, iskana ilaali burburka kulaylka; heerkulka qaybta madaxa dhimashadu wax yar ayuu ka hooseeyaa qaybta isku-darka, which is to ensure the shaping effect of the strips.
• Cadaadiska Soo Bixinta: The extrusion pressure is generally 3-15MPa. Cadaadiska ku jira godka extrusion waxaa inta badan lagu go'aamiyaa saamiga isku-buufinta ee furaha, cabbirka godka dhinta iyo xawaarihiisa isku dhufashada. Cadaadiska extrusionka ayaa sarreeya, the better the mixing and dispersing effect of the materials, and the denser the masterbatch particles. Si kastaba ha ahaatee, haddii cadaadisku aad u sarreeyo, waxay kordhin doontaa isticmaalka tamarta iyo xirashada qalabka, oo xitaa sababa in madaxa dhiman uu xannibo; if the pressure is too low, the materials cannot be fully compressed and mixed, the masterbatch particles are loose, and the performance is unstable.

2.3.5 Die Head Structure:

The die head structure mainly includes the number, shape and size of die holes. The shape of the die hole determines the cross-sectional shape of the extruded strips (such as circular, square), and the size of the die hole determines the initial diameter of the strips and the final particle size of the masterbatch. The smaller the die hole size, the greater the extrusion pressure, the better the mixing and dispersing effect, but the production capacity will be reduced; 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. The number of die holes affects the production capacity; the more the number of die holes, the higher the production capacity, but it is necessary to ensure that the pressure distribution is uniform, so as to avoid uneven thickness of the strips and uneven particle size of the masterbatch.

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, bacaha qashinka), the mixing ratio can be 5%-20% (using low-to-medium filling calcium carbonate filler masterbatch);
• For plastic products with medium performance requirements (sida filimada caaga ah, 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 (sida qaybaha baabuurta, electronic product shells, filimada heerka sare), 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 (sare 1250 mesh) 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 (such as PE, PP, PVC). The specific steps are: marka hore, qalaji qaybaha balaastigga ah ee salka ah iyo buuxinta masterbatch si aad qoyaanka uga saarto (waxa ku jira qoyaanka waa in hoos lagu xakameeyaa 0.5%); markaas, Geli qaybaha balaastigga ah iyo buuxinta masterbatch gelinta isku-darka xawaare sare leh iyadoo loo eegayo saamiga isku dhafka la go'aamiyay, oo ku dar qadar ku habboon oo saliid ah (haddii loo baahdo) in la isku daro si isku mid ah. Xawaaraha isku dhafka ah waa guud ahaan 500-800 rpm, iyo wakhtiga isku darka waa 3-5 daqiiqado. Ka dib marka la isku daro, isku darka waxaa si toos ah loogu diri karaa extruder ama mishiinka qaabaynta irbado si ay u habeeyaan. Faa'iidooyinka isku dhafka qallalan waa hawl fudud, waxtar sare leh, qiimo jaban oo aan wasakhayn alaabta.
• Isku dhafka qoyan: Habkani wuxuu ku habboon yahay filler masterbatch oo leh kala firdhinta liidata ama balaastig sal leh oo leh viscosity sare (sida koollada PVC). The specific steps are: qas Masterbatch filler iyo qadar ku haboon ee dareere ah (sida balaastiiste, saliid dareere ah) in la sameeyo koollo, dabadeed koollada ku dar balaastiigga saldhigga oo walaaq si isku mid ah, oo ugu dambeyntii ka saar dareeraha adoo kululeynaya ama qalajinaya. Faa'iidooyinka isku dhafka qoyan waa saameyn wanaagsan oo isku dhafan iyo kala firdhisanaan isku mid ah ee masterbatch; qasaarooyinku waa hawlgal adag, kharash badan, iyo dareere hadhaaga ah oo fudud oo saameeya tayada alaabta. Sidaa darteed, isku dhafka qoyan waxaa loo isticmaalaa kaliya xaalado gaar ah.

4.2.3 Hagaajinta Hababka Habaynta:

Marka lagu daro filler masterbatch farsamaynta balaastikada, xuduudaha processing (sida heerkulka, cadaadis, xawaarihii xawaaruhu) waxay u baahan yihiin in si sax ah loo hagaajiyo iyadoo loo eegayo nooca iyo tirada buuxinta ee masterbatch si loo hubiyo horumarka siman ee habaynta iyo tayada badeecada ugu dambeysa.

Tusaale ahaan, marka lagu farsameeyo balaastiig PE oo leh kaalshiyam kaarboonaydh filler masterbatch, heerkulka processing waxaa lagu kordhin karaa by 5-10 ℃; marka lagu farsameeyo balaastiig PP oo leh talc filler masterbatch, heerkulka processing waxaa lagu kordhin karaa by 10-15 ℃. Waa in la ogaadaa in heerkulku aanu noqon mid aad u sarreeya si looga fogaado kala-goynta kulaylka ee balaastigga saldhigga ah iyo waxyaabaha lagu daro..
• Hagaajinta Cadaadiska: Ku darida filler Masterbatch waxay kordhin doontaa iska caabbinta inta lagu jiro farsamaynta, markaas cadaadiska processing (cadaadiska extrusion, cadaadiska duritaanka) u baahan in si habboon loo kordhiyo 10%-20%. Tusaale ahaan, marka laga saaro tuubooyinka balaastikada ah oo leh filler masterbatch, cadaadiska extrusion waxaa lagu kordhin karaa 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: Filler masterbatch (especially calcium carbonate, talc masterbatch) is easy to absorb moisture, which will cause bubbles, pinholes and other defects in the final product. Sidaa darteed, the masterbatch should be stored in a dry, bakhaar qabow oo hawo leh, and should be dried before use (the drying temperature is 80-100℃, and the drying time is 2-4 saacadood).
• Compatibility: The carrier resin of the filler masterbatch should be consistent with or compatible with the base plastic of the product. Tusaale ahaan, 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, taasoo keentay kala daadsanaan liidata iyo hoos u dhaca waxqabadka alaabta.
• Isku darka lebbiska: Filler Masterbatch iyo balaastikada salka waa in la isku qaso si isku mid ah. Haddii isku darka uu yahay mid aan sinnayn, agglomeration maxaliga ah ee masterbatch ayaa dhici doona, resulting in defects such as white spots, dhibco madow iyo agglomeration ee alaabta, saameynaya muuqaalka iyo waxqabadka alaabta.
• Xakamaynta qiyaasta: Qiyaasta buuxinta masterbatch waa in aanay dhaafin inta ugu badan ee buuxinta ee lagu dabaqi karo qalabka iyo waxqabadka alaabta. Qiyaasta xad-dhaafka ah waxay u horseedi doontaa kala-bax xumo, adkaanta hoose, dareere ka shaqayneed liidata iyo dhibaatooyinka kale ee alaabta; qiyaasta aan ku filnayn ma gaari doonto saameynta dhimista kharashka iyo horumarinta waxqabadka.
• Muddada Kaydinta: Filler Masterbatch waxay leedahay wakhti kaydin gaar ah (generally 6-12 bilo). Haddii muddada kaydinta la dhaafo, Masterbatch waxay nuugi kartaa qoyaanka, agglomerate or the performance of additives may degrade, affecting the use effect. Sidaa darteed, the masterbatch should be used within the storage period.
