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, aito, pereoo, 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, te re'are'a, extruding and granulating inorganic fillers (such as calcium carbonate, talc, barium sulfate, e tē vai atura.) with polymer carriers (such as polyethylene, polypropylene, polyvinyl chloride, e tē vai atura.) and appropriate additives (such as dispersants, compatibilizers, hinu hinu, e tē vai atura.) in a certain proportion. Te ohipa rahi o ta ' na ohipa, o te faaitiraa ïa i te moni no te hamani i te mau tao'a hu'ahu'a ma te haamaitai aore ra te tapearaa i te huru tumu o te mau tao'a hu'ahu'a.

Ia au i te mau haamaramaramaraa tano, Ua maraa te rahi o te matete o te ao nei 20 miria dala US, e te tohuhia ra e e tapea te reira i te hoê faito maraaraa 6%-9% i roto i te mau matahiti i muri iho. I rotopu ia ratou, tao'a tahi (CaCO3) O te masterbatch te huru tao'a faaohipa-pinepine-roa ' ' e-hia, hau atu i te 60% o te matete masterbatch taatoa, i muri mai i te masterbatch no te faaî i te talc, barium sulfate (BaSO4) masterbatch e te tahi atu mau masterbatch taa ê. O te fenua Asia e Pacific te matete rahi roa'e i te ao nei no te hamaniraa e no te hoo mai i te mau tao'a, hau atu i te 50% o te matete o te ao nei, no te tupuraa oioi o te ohipa hamaniraa tauihaa hu'ahu'a i te fenua Taina, India e te tahi atu mau nunaa, the huge demand for cost reduction and performance improvement of plastic products, and the continuous improvement of industrial supporting capacity.

The development trend of the filler masterbatch industry is mainly reflected in four aspects: first, high performance and functionalization. With the upgrading of downstream plastic product requirements, filler masterbatch is no longer limited to cost reduction, but gradually develops towards functionalization, such as improving the rigidity, toughness, te patoiraa i te veavea, weather resistance and barrier properties of plastic products, and developing special functional filler masterbatches such as flame retardant, antistatic and antibacterial; second, high filling amount and good dispersibility. Under the premise of ensuring product performance, increasing the filling amount of inorganic fillers can further reduce production costs, 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; third, environmental protection and low pollution. With the strengthening of global environmental protection policies and the improvement of environmental protection awareness, 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; fourth, 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, improving production efficiency, reducing labor costs and ensuring product quality stability.

Against this background, extrusion granulation technology, as the core technology of filler masterbatch production, has become the key to determining the quality of filler masterbatch and the competitiveness of enterprises. The performance of extruders directly affects the dispersibility, particle shape, melting index and other key indicators of filler masterbatch. No te pahono i te mau huru o te ohipa tapihooraa e te mau hinaaro o te matete, ua hamanihia mai ta tatou mau rave'a hamaniraa tauihaa toro'a e te mau rave'a hamaniraa tauihaa no te faaî i te masterbatch, o te nehenehe e faatitiaifaro maitai i te mau vahi o te mauiui i roto i te faanahoraa masterbatch (mai te ereraa i te parareraa, te rahi o te hu'ahu'a, iti o te moni faaî, Te faaohiparaa i te ito rahi, e tē vai atura.) e te tautururaa i te mau taiete ia faatupu i te mau hamaniraa tauihaa teitei e te aravihi.

E mau huru taa ê to te mau huru masterbatch atoa e to ratou iho mau huru tupuraa. Teie i muri nei te hoê omuaraa parau taa maitai no nia i te faanahoraa matauhia e te mau huru tumu o te filler masterbatch:

Ia au i te huru o te faaîraa inorganic, E nehenehe te reira e faataahia na roto i te rahiraa o te taime (CaCO3) masterbatch faaî, talc, barium sulfate (BaSO4) masterbatch faaî, e te tahi atu mau masterbatches taa ê (mai te kaolin, Masterbatch no te faaî i te carbon ereere, Masterbatch no te faaî i te mau hu'ahu'a hi'o, e tē vai atura.).

• Te tao'a tahi (CaCO3) Masterbatch: O te reira te masterbatch faaohipa-pinepine-roa ' ' e-hia e te hoo iti roa ' ' e. I te rahiraa o te taime, o te tao'a tahi mâmâ aore ra te tao'a tahi teimaha. E mau hu'ahu'a rahi to te carbonate mâmâ, te parareraa maitai e te uouo teitei, o te tano ïa no te mau tao'a hu'ahu'a e hinaaro rahi to ratou i te hoho'a e te maitai (mai te mau hoho'a teata, te mau tao'a tairiraa); E mea etaeta roa te carbonate teimaha, te pato'iraa i te ahu maitai e te hoo iti, which is suitable for plastic products with high requirements on rigidity and cost control (such as woven bags, packaging belts, nga paipa, e tē vai atura.). Calcium carbonate filler masterbatch can not only reduce production costs, but also improve the rigidity, heat resistance and dimensional stability of plastic products, and has a certain lubricating effect, which can improve the processing fluidity of plastics.
• 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, and is widely used in automotive parts, home appliance shells, plastic pipes and other fields that require high performance.
• Barium Sulfate (BaSO4) 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 (mai te mau hoho'a teata, plastic bottles, medical plastic products, e tē vai atura.), and can also be used in radiation-proof plastic products (such as medical protective equipment, nuclear power plant accessories, e tē vai atura.).

1.2.2 Classification by Carrier Resin:

According to the type of carrier resin used, filler masterbatch can be divided into polyethylene (PE) masterbatch faaî, polypropylene (PP) masterbatch faaî, polyvinyl chloride (PVC) masterbatch faaî, polyethylene terephthalate (RIMA'ERE) masterbatch faaî, etc. The selection of carrier resin is mainly determined by the type of downstream plastic products. Moekara, PE filler masterbatch is suitable for PE plastic products (mai te mau hoho'a teata, bags, nga paipa); PP filler masterbatch is suitable for PP plastic products (such as woven bags, injection molding parts, automotive parts); PVC filler masterbatch is suitable for PVC plastic products (such as PVC pipes, Te mau hoho'a, mau api).

1.2.3 Classification by 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, etc. 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, and maintains good transparency and toughness; injection-grade filler masterbatch requires good fluidity and uniform particle size, no te farii i te huru raveraa vitiviti e no te haapapu i te hoho'a e te faito o te mau tao'a tairiraa; E mea titauhia te hoê vai-maitai-raa o te ve'ave'a e te mau rave'a matini, no te faaafaro i te huru o te mau paipa no te anuvera rahi e te faaheporaa teitei, te mau hoho'a e te tahi atu mau tao'a.

1.2.4 Te faanahoraa na roto i te faaîraa i te moni:

Ia au i te rahiraa o te mau faaîraa inorganic, E nehenehe te masterbatch e faataahia ei masterbatch iti (faaî i te moni 30%-50%), masterbatch (faaî i te moni 50%-70%) e te masterbatch teitei (faaî i te moni 70% e i ni'a). E faataahia te faito o te faaîraa ia au i te mau hinaaro o te mau tao'a i raro mai e te aravihi no te faaohipa i te mau ravea. E mea papû a'e te hoê faahopearaa no te faaiti i te moni o te masterbatch, 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. I rotopu ia ratou, 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. Therefore, No te haapapû i te parareraa e te huru o te mau rave'a haaparareraa masterbatch, e mea faufaa roa ia ma'iti i te mau rave'a aravihi e te mau rave'a aravihi apî.

E mau maitai to ' na no te aravihi rahi no te hamaniraa, te huru maitai o te tao'a, te aravihi no te farii i te mau tao'a mata e te mau rave'a faaohiparaa rahi. I roto i te hamaniraa i te masterbatch, E faaohipa-pinepine-hia te mau ravea aravihi apî no te ite i te parareraa hoê â huru o te mau tao'a faaî i roto i te mau tao'a amo, faarehu e a faaî i te ranu, e i muri iho, a huti e a huti i te mau hu'ahu'a no te hamani i te hoê masterbatch faaî i te mau hu'ahu'a e hoê â rahi, 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 (mai te PE, PP, PVC) e te mau tao'a (such as dispersants, compatibilizers, hinu hinu, antioxidants, e tē vai atura.). The characteristics of these raw materials are quite different, which puts forward special requirements for extrusion equipment:

A tahi, 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.

Ha'iti, 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.

Tātou, the processing temperature range is narrow. E mau vahi re'are'a e te vai - maitai - raa o te mau hu'ahu'a amo e rave rau. Moekara, te vahi re'are'a o te PE e 100-130°C, te vahi re'are'a o te PP e 160-170°C, e mea ohie roa ia parari te PVC i te anuvera rahi (hau atu i te 160°C). Therefore, E titauhia te hoê aravihi no te faatere i te anuvera no te haapapu e ua rewa roa te anoiraa ma te ore e parari i te veavea, e no te ape i te parariraa o te mau tao'a faaî e te inoraa o te ohipa o te tao'a.

Ia au i te mau huru i faahitihia i nia nei, E ere te mau rave'a haaparareraa parau hoê i te mea tano no te hamaniraa i te mau rave'a rahi e te maitai roa. No te mea ho'i e, e vahi iti roa te extruder, aita e aravihi no te pâmu ia'na iho e aita e hopearaa no te tamâ ia'na iho. I te taime a faaapî ai i te mau anoiraa teitei e te mau anoiraa teitei, E mea ohie roa ia haaputuputu i te mau tao'a materia, 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.

Te mau hu'ahu'a, i te tahi a'e pae, 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. The intermeshing and rotating of the twin screws can generate strong shear force and kneading force, which can fully break the agglomerates of inorganic fillers, make the fillers uniformly dispersed in the polymer carrier, and ensure the dispersibility and stability of the product. In addition, the twin-screw extruder has good temperature control accuracy, strong adaptability to raw materials, and can adapt to the processing of different types, different filling amounts of filler masterbatch, and has high production efficiency and low energy consumption.

2.2 Working Principle of Filler Masterbatch Extrusion Granulation

The extrusion granulation process of filler masterbatch is a complex physical and chemical process, which involves the interaction of multiple factors such as temperature, Pouhōʻā, shear force and time. The specific working principle and process flow are as follows:

A tahi, raw material pretreatment. The raw materials of filler masterbatch (inorganic fillers, resin amo, additives) need to be pretreated to ensure the quality of the final product. 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. Therefore, 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 (mai te 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, compatibilizers, hinu hinu, e tē vai atura.) are put into a high-speed mixer for premixing. The mixing speed is generally 800-1200 rpm, and the mixing time is 5-10 miniti. 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, reduce the surface energy of the filler, prevent the filler from agglomerating, and improve the dispersibility of the filler in the carrier resin.

Ha'iti, feeding and conveying. The premixed mixture is sent to the feeding hopper of the twin-screw extruder through a screw feeder or a belt feeder. The feeding speed needs to be uniform and stable, which is matched with the screw speed and extrusion speed of the extruder, to ensure that the materials enter the extrusion cavity stably and avoid material accumulation or insufficient feeding. The feeding device of the extruder is usually equipped with a frequency conversion speed regulation function, which can adjust the feeding speed according to the actual production situation.

Tātou, te re'are'a, mixing and shearing. 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, e te iti noa ' tura te rahi o te apoo extrusion i nia i te e'a. Ia huri ana'e te mau viti, E tata'ihia te mau tao'a i raro a'e i te ohipa a te mau viti e te farii, e te faaheporaa i roto i te apoo extrusion e maraa mǎrû noa (3-15MPa). I te hoê â taime, E faaruru te mau tao'a i te puai kutikuti e te puai o te mau hu'ahu'a tei tupu mai na roto i te tereraa i rotopu i te mau viti e te farii, e i rotopu atoa i te mau manureva.

E nehenehe te puai kutikuti e te puai o te friction e ofati roa i te mau hu'ahu'a o te mau tao'a faaî, A faaî i te mau mea faaî ia parare hoê â huru i roto i te hu'ahu'a afa'i, e te faaitoitoraa i te hoêraa e te taairaa i rotopu i te mau mea faaî e te mau mea amo. E nehenehe atoa te puai o te friction e faatupu i te hoê faito veavea, o te amuihia ' tu i te faahanahanaraa i rapae i te farii (te faahanahana uira e aore râ, te faahanahanaraa) no te faariro mǎrû noa i te hu'ahu'a e no te faariro i te hu'ahu'a. I te rahiraa o te taime, e amahamaha te farii o te extruder i roto i te 3-6 mau tuhaa no te faatere i te anuvera (tuhaa tamaaraa, tuhaa melting, tuhaa anoiraa, tuhaa homogenization, e tē vai atura.), e te anuvera o te mau tuhaa atoa e haapaohia ra ïa ia au i te huru o te mau hu'ahu'a e te mau hu'ahu'a. Moekara, ia faaapî ana'e outou i te masterbatch PE, te anuvera o te tuhaa tamaaraa e 80-100°C, te tuhaa re'are'a e 120-140°C, te tuhaa anoiraa e 140-150°C, e te tuhaa fenua e 130-140°C; ia faaohipa ana'e outou i te masterbatch PP, e 20-30°C te anuvera o te mau tuhaa atoa i ni'a a'e i te anuvera o te PE.

Te maharaa, te faaho'i-faahou-raa e te faahoho'araa. Te re'are'a taatoa, 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.

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 miniti. Ma te toetoe oioi, e nehenehe te mau hu'ahu'a e haapuai oioi noa, Tauturu i te hoho'a e te rahi o te mau auri, e te ape i te faainoraa. I muri a'e i te toetoeraa, E tonohia te mau hu'ahu'a i te hoê granulator no te tâpû. Ua faautahia te granulator i te hoê maripi hu'ahu'a, o te nehenehe e tâpû i te mau hu'ahu'a ei mau hu'ahu'a granular masterbatch e te rahi hoê â (e 2-5mm te rahi o te hu'ahu'a, e nehenehe e tauihia ia au i te mau hinaaro o te taata hoo). No te haapapu e e au hoê â te rahiraa o te mau hu'ahu'a o te masterbatch, ua faaauhia te vitiviti o te tipi huti i te vitiviti o te mau hu'ahu'a.

Te ono, te hi'opo'araa e te tapo'iraa. E tonohia te masterbatch i nia i te hoê mata aueue no te hi'opoa, o te nehenehe e faaore i te mau hu'ahu'a aita i au (mai te rahi roa, te mau hu'ahu'a na'ina'i roa e aore râ, te mau hu'ahu'a) e ia haapapû i te hoê â huru o te tao'a. I muri iho, e tonohia te masterbatch aravihi i roto i te hoê mītini tapo'i aunoa no te tapo'i. E nehenehe te mau tapao o te afata e tauihia ia au i te mau hinaaro o te taata hoo (mai te 25kg/pute, 50kg/pute), E mea ti'a ia tapo'ihia te afata e ia tape'a i te haumi no te arai i te masterbatch ia ore ia mimiti i te haumi e ia faaino i te huru. I muri a'e i te tapo'iraa, E tapeahia te mau tao'a i roto i te hoê vahi maro, fare vairaa tauihaa to'eto'e e te hau.

2.3 Te mau mea faufaa roa e faaino ra i te mau faahopearaa o te mau hu'ahu'a

E ohipa oioi te mau faahopearaa o te mau hu'ahu'a i nia i te huru o te masterbatch. E rave rahi mau mea o te faaino i te faahopearaa o te granulation, e tae noa'tu i te mau huru o te mau tao'a mata, faito formula, Te mau faahopearaa, Te mau tapa'o extrusion e te hamaniraa i te upoo. 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 Raw Material Characteristics:

The type, particle size, moisture content and purity of raw materials have a great impact on the granulation effect. Moekara, 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. The purity of raw materials is also very important; impurities in raw materials (such as stones, metals, dust) 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; E faaiti te faito faaîraa iti roa i te faahopearaa o te faaitiraa mai i te moni. E tia ia faaau - atoa - hia te huru e te faito o te mau tao'a faaî. Moekara, i te rahiraa o te taime, e 1%-3% o te faito o te faaîraa; Na te iti roa o te dispersant e faatupu i te ereraa i te parareraa o te faaî, e te rahiraa o te mau tao'a parare, e faaino ïa i te taairaa i rotopu i te masterbatch e te mau tao'a hu'ahu'a i raro, e faaiti i te mau huru matini o te mau tao'a. E faaohipahia te rave'a no te haamaitai i te taairaa i rotopu i te taata faaî e te rave'a amo; i te rahiraa o te taime, e 0.5%-2%, o te nehenehe e haamaitai rahi i te parareraa e te mau huru o te masterbatch. E faaohipahia te hinu no te faaiti i te mârôraa i rotopu i te mau tao'a e te hi'o, barrel e te upoo pohe, haamaitai i te huru o te faanahoraa, and prevent the materials from sticking to the equipment; i te rahiraa o te taime, e 0.3%-1%.

2.3.3 Premixing Effect:

Premixing is the foundation of extrusion granulation. The uniformity of premixing directly affects the dispersibility of the filler in the carrier resin. If the premixing is uneven, the additives cannot be uniformly adhered to the surface of the filler and carrier, resulting in local agglomeration of the filler, uneven mixing of the materials during extrusion, and poor quality of the masterbatch. To ensure the premixing effect, it is necessary to control the mixing speed, mixing time and mixing temperature. The mixing speed is generally 800-1200 rpm, the mixing time is 5-10 miniti, 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.

• Screw Speed: The screw speed generally ranges from 150 a 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. Āre'a, 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; if the screw speed is too low, the shear force and friction force are insufficient, 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.
• Extrusion Temperature: The extrusion temperature is divided into multiple sections (tuhaa tamaaraa, tuhaa melting, tuhaa anoiraa, tuhaa homogenization, die head section), and the temperature of each section needs to be precisely controlled according to the type of carrier resin and filler. The temperature of the feeding section is lower (slightly higher than the melting point of the carrier resin), which is mainly to prevent the materials from caking and ensure smooth feeding; the temperature of the melting section is medium, which is mainly to promote the melting and plasticization of the carrier resin; the temperature of the mixing section is higher, which is mainly to enhance the shear and mixing effect, 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.
• Extrusion Pressure: The extrusion pressure is generally 3-15MPa. The pressure in the extrusion cavity is mainly determined by the compression ratio of the screw, the die hole size and the screw speed. The higher the extrusion pressure, the better the mixing and dispersing effect of the materials, and the denser the masterbatch particles. Āre'a, if the pressure is too high, E faarahi te reira i te faaohiparaa i te ito e te mauiui o te mau ravea, e tae noa ' tu te faatupu i te upoo o te pohe; mai te mea e, e mea iti roa te faaheporaa, Eita te mau tao'a e nehenehe e faaî roa e e anoihia, E mea maamaa roa te mau hu'ahu'a masterbatch, e aita te ha'utiraa i papû.

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 Te faataaraa i te faito o te anoiraa:

Te faito o te anoiraa o te masterbatch e te hu'ahu'a niu (te mau tao'a hu'ahu'a) E faataahia te reira na roto i te rahiraa o te faaîraa o te masterbatch, te mau titauraa no te rave i te ohipa o te tao'a hopea e te aravihi no te faaapî i te mau ravea. Te faito faito o te anoiraa, o te 1%-20%, e e nehenehe te faito taa ê e tauihia ia au i te mau mana'o tumu i muri nei:

• No te mau tao'a hu'ahu'a e mea iti roa te mau titauraa no te rave i te ohipa e te mau titauraa no te faatere i te moni rahi (mai te mau pute hu'ahu'a matauhia, Te mau pute hu'ahu'a), e nehenehe te faito anoiraa e 5%-20% (ma te faaohipa i te hoê rave'a no te faaî i te tao'a tahi carbonate);
• No te mau tao'a hu'ahu'a e mau titauraa no te ha'utiraa (mai te mau hoho'a teata, te mau tuhaa injection matauhia), e nehenehe te faito anoiraa e 2%-8% (ma te faaohipa i te carbonate no te faaî i te tao'a tahi, talc e aore râ, barium sulfate);
• No te mau tao'a hu'ahu'a e mau titauraa rahi to te reira (such as automotive parts, mau hu'ahu'a roro uira, high-grade films), e nehenehe te faito anoiraa e 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 (i ni'a 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 (mai te PE, PP, PVC). Te mau taahiraa taa ê, o te: first, no te faaore i te haumi, a faamaroo i te mau hu'ahu'a hu'ahu'a tumu e te masterbatch (E mea ti'a ia haapa'ohia te faito haumi i raro nei 0.5%); i muri, Ia au i te faito i faataahia, a tuu i te mau hu'ahu'a hu'ahu'a niu e te mau hu'ahu'a faaî i roto i te hoê rave'a anoiraa vitiviti, e a tapiri i te hoê faito hinu e tano (mai te mea e, e titauhia) no te anoi hoê â. The mixing speed is generally 500-800 rpm, and the mixing time is 3-5 miniti. I muri a'e i te anoiraa, E nehenehe te anoiraa e tono - tia - hia i nia i te matini neneiraa aore ra te matini neneiraa no te faaapî. E mea ohie roa te mau maitai o te faaineineraa maro, aravihi rahi, e ere i te mea ino roa e aita e pohe i nia i te tao'a.
• Te anoiraa: E mea au teie ravea no te faaî i te masterbatch e ere i te mea ino roa, aore ra no te mau hu'ahu'a niu e te mau hu'ahu'a teitei (mai te PVC). Te mau taahiraa taa ê, o te: A ano'i i te masterbatch e te hoê faito tao'a tano e au (mai te mau hu'ahu'a, hinu) no te hamani i te hoê tapo'iraa, I muri iho, a tuu i te tapo'i i ni'a i te hu'ahu'a tumu e a faaûru hoê â, e i te pae hopea, a tatara i te reira na roto i te faahanahanaraa aore ra te faamaraa. Te mau maitai o te anoiraa mâ, o te hoê ïa anoiraa maitai e te parareraa hoê â huru o te masterbatch; E ohipa fifi roa te mau ati, moni rahi, e te toea o te tao'a ohie o te faaino i te huru o te tao'a. Therefore, I roto noa i te mau tupuraa taa ê, e faaohipa - noa - hia te anoiraa mâ.

4.2.3 Te tauiraa o te mau rave'a faatere:

Ia tuu ana'e outou i te masterbatch i roto i te hamaniraa hu'ahu'a, te mau taahiraa no te faatereraa (mai te anuvera, Pouhōʻā, te vitiviti) E tia ia tauihia te reira ia au i te huru e te rahiraa o te masterbatch no te haapapu i te haereraa i mua maitai o te faanahoraa e te huru o te tao'a hopea.

• Te faaafaroraa i te anuvera: E faarahi te faaôraa ' tu i te masterbatch i te î o te anoiraa, so the processing temperature needs to be appropriately increased by 5-15℃ compared with the processing temperature of pure base plastic. Moekara, 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 (extrusion pressure, injection pressure) needs to be appropriately increased by 10%-20%. Moekara, 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, E tia ia haapaohia te mau faaararaa i muri nei no te ape i te faainoraa i te huru o te hamaniraa e te huru o te mau tao'a:

• Te arairaa i te haumi: Filler masterbatch (te tao'a tahi iho â râ, talc masterbatch) E mea ohie roa ia huti i te haumi, o te faatupu i te mau hu'ahu'a, te mau apoo e te tahi atu mau hape i roto i te tao'a hopea. Therefore, E mea ti'a ia tape'ahia te masterbatch i roto i te hoê vahi maro, fare vairaa tauihaa to'eto'e e te hau, e e mea ti'a ia faamaroo hou a faaohipa ' i (e 80-100°C te anuvera, e te taime no te faamaraa 2-4 hora).
• Te tu'atiraa: E tia i te hu'ahu'a afai o te masterbatch ia tu'ati aore râ ia tu'ati i te hu'ahu'a niu o te tao'a. Moekara, E mea ti'a ia faaohipahia te masterbatch PE e te hu'ahu'a PE, e e mea ti'a ia faaohipahia te masterbatch PP e te hu'ahu'a PP. Mai te mea e, aita te hu'ahu'a amo e tano i te hu'ahu'a niu, E ohipa te reira i nia i te taairaa i rotopu i te masterbatch e te ahu niu, 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, resulting in defects such as white 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 (generally 6-12 ava'e). If the storage period is exceeded, the masterbatch may absorb moisture, agglomerate aore ra te ohipa o te mau tao'a tahi e nehenehe e ino, te faainoraa i te faahopearaa o te faaohiparaa. Therefore, E ti'a ia faaohipahia te masterbatch i roto i te taime no te tape'araa.

5. Te mau fifi e te mau faatitiaifaroraa matauhia i roto i te hamaniraa i te Filler Masterbatch

I roto i te ohipa hamaniraa i te masterbatch, no te mana o te mau tao'a mata, formula, te mau rave'a haaparareraa e te mau rave'a haaparareraa, E nehenehe e tupu mai te mau fifi e rave rahi, o te faaino i te huru e te aravihi no te hamaniraa i te masterbatch.

5.1 Te mau fifi matauhia o te Filler Masterbatch e to ratou mau faatitiaifaroraa

5.1.1 Te ereraa i te parareraa o te Masterbatch:

This is the most common quality problem in filler masterbatch production. The main manifestations are: the masterbatch has agglomeration, and after mixing with the base plastic, white spots, black spots or agglomeration appear in the final product, which affects the appearance and performance of the product.

Te mau tumu: 1) The particle size of the inorganic filler is too large or uneven, and the agglomerates are not broken during premixing; 2) The dosage of dispersant is insufficient or the type of dispersant is inappropriate, which cannot effectively prevent the agglomeration of the filler; 3) The premixing effect is poor, and the filler, carrier resin and additives are not mixed uniformly; 4) The shear force of the extruder is insufficient, and the agglomerates of the filler cannot be fully broken during extrusion; 5) E mea iti roa te anuvera o te faanahoraa, e aita te hu'ahu'a amo i reva roa, o te faaino i te parareraa o te faaîraa.

Te mau faatitiaifaroraa: 1) A maiti i te mau hu'ahu'a inorganic e te rahi o te mau hu'ahu'a maitai e te hoê â faito (generally 800-2000 mesh), e a hi'o i te mau mea faaî hou a faaohipa ' i no te iriti i te mau hu'ahu'a rarahi e te mau hu'ahu'a; 2) Faarahi i te faito o te dispersant (i roto i te area o 1%-3% o te faito o te faaîraa) e aore râ, a mono i te reira na roto i te hoê tao'a haaparare e tu'ati i te resin faaî e te mau rave'a afa'i; 3) A faaafaro i te huru raveraa a te premixing, faarahi i te vitiviti o te anoiraa (800-1200 rpm) e te taime no te anoiraa (5-10 miniti), e no te haamaitai i te huru o te anuvera i te 40-60°C; 4) A taui i te hamaniraa o te extruder, faarahi i te numera o te mau hu'ahu'a kutikuti, e aore râ, a faarahi i te vitiviti o te hi'o no te haamaitai i te puai kutikuti; 5) No te haapapû e, ua rewa roa te hu'ahu'a, a faarahi i te anuvera o te rave'a haaparareraa, which is conducive to the dispersion of the filler.

5.1.2 Uneven Particle Size of Filler Masterbatch:

The main manifestations are: the particle size of the masterbatch varies greatly, some particles are too large, some are too small, and there are more powdery materials, which affects the fluidity of the masterbatch and the uniformity of mixing with the base plastic.

Te mau tumu: 1) The size of the die hole of the extruder die head is uneven or blocked; 2) The extrusion speed and the cutting speed of the granulator are not matched; 3) The cooling effect is poor, and the strips are not fully solidified before cutting, resulting in uneven cutting; 4) The viscosity of the mixture is uneven, and the extrusion speed of the strips is inconsistent.

Te mau faatitiaifaroraa: 1) Clean the die head regularly, check and replace the die plate with uneven die holes, ensure that the size of each die hole is consistent; 2) Adjust the extrusion speed and the cutting speed of the granulator to make them matched (the cutting speed should be slightly higher than the extrusion speed of the strips); 3) Optimize the cooling process, increase the cooling water flow or extend the cooling time, ensure that the strips are fully solidified (the surface temperature of the strips after cooling is 20-30℃); 4) Adjust the formula ratio and processing parameters to ensure the uniform viscosity of the mixture, and avoid the inconsistency of the extrusion speed of the strips.

5.1.3 Low Melting Index of Filler Masterbatch

The main manifestations are: the fluidity of the masterbatch is poor, it is difficult to mix with the base plastic during processing, and the processing efficiency is low, which even leads to equipment blockage.

Te mau tumu:

• The filling amount of the filler is too high, which increases the viscosity of the masterbatch and reduces the fluidity;
• The type of carrier resin is inappropriate (the melting index of the carrier resin is too low);
• E mea iti roa te anuvera o te faanahoraa, e aita te hu'ahu'a amo i reva roa;
• The dosage of lubricant is insufficient, which increases the friction between the materials and affects the fluidity.

Te mau faatitiaifaroraa:

• Reduce the filling amount of the filler appropriately, or select a filler with better dispersibility to improve the fluidity;
