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, pangwangunan, otomotif, 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, lebur, extruding and granulating inorganic fillers (such as calcium carbonate, talc, barium sulfate, jsb.) with polymer carriers (such as polyethylene, polipropilén, polyvinyl chloride, jsb.) and appropriate additives (such as dispersants, compatibilizers, pelumas, jsb.) in a certain proportion. Its core function is to reduce the production cost of plastic products while improving or maintaining the basic performance of plastic products.

According to relevant data statistics, the global filler masterbatch market size has exceeded 20 billion US dollars, and it is expected to maintain a growth rate of 6%-9% in the next few years. Among them, kalsium karbonat (CaCO3) filler masterbatch is the most widely used product type, akuntansi pikeun leuwih ti 60% of the total filler masterbatch market, followed by talc filler masterbatch, barium sulfate (BaSO4) filler masterbatch and other special filler masterbatches. The Asia-Pacific region is the world’s largest filler masterbatch production and consumption market, akuntansi pikeun leuwih ti 50% of the global market share, which is mainly due to the rapid development of the plastic processing industry in China, India and other countries, paménta badag pikeun ngurangan ongkos jeung perbaikan kinerja produk plastik, jeung perbaikan kontinyu kapasitas ngarojong industri.

Tren pangembangan industri masterbatch pangisi utamina ditingali dina opat aspék: kahiji, kinerja tinggi na functionalization. Kalayan paningkatan syarat produk plastik hilir, masterbatch filler henteu deui dugi ka pangurangan biaya, tapi laun-laun ngembang ka arah fungsionalisasi, kayaning ngaronjatkeun rigidity nu, kateguhan, lalawanan panas, lalawanan cuaca jeung sipat panghalang produk plastik, sareng ngembangkeun masterbatches pangisi fungsional khusus sapertos retardant seuneu, antistatik sareng antibakteri; kadua, jumlah keusikan tinggi na dispersibility alus. Dina premis pikeun mastikeun kinerja produk, 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. Our professional extruders and granulation production lines for filler masterbatch are developed in response to the characteristics of the industry and market demand, which can effectively solve the pain points in filler masterbatch processing (such as poor dispersibility, uneven particle size, low filling amount, high energy consumption, jsb.) and help enterprises achieve high-quality and efficient production.

1.2 Classification of Filler Masterbatch and Its Core Characteristics

Filler masterbatch can be divided into different types according to the type of filler, carrier resin, application field and filling amount. Each type of filler masterbatch has its own unique characteristics and applicable scenarios. The following is a detailed introduction to the common classification and core characteristics of filler masterbatch:

1.2.1 Klasifikasi ku Tipe Filler:

Ieu mangrupikeun metode klasifikasi anu paling umum pikeun masterbatch pangisi. Numutkeun jinis pangisi anorganik, eta bisa utamana dibagi kana kalsium karbonat (CaCO3) pangisi masterbatch, talc filler masterbatch, barium sulfate (BaSO4) pangisi masterbatch, sareng masterbatches pangisi khusus anu sanés (kayaning kaolin filler masterbatch, karbon hideung filler masterbatch, serat kaca filler masterbatch, jsb.).

• Kalsium Karbonat (CaCO3) Pangeusi Masterbatch: Ieu mangrupikeun masterbatch pangisi anu paling seueur dianggo kalayan biaya panghandapna. Pangisi utamana kalsium karbonat hampang atanapi kalsium karbonat beurat. Kalsium karbonat hampang gaduh ukuran partikel anu saé, dispersibility alus tur whiteness tinggi, nu cocog pikeun produk plastik kalayan sarat tinggi dina penampilan sarta fineness (kayaning film plastik, produk suntik molding); kalsium karbonat beurat boga karasa tinggi, lalawanan maké alus sarta harga low, which is suitable for plastic products with high requirements on rigidity and cost control (such as woven bags, packaging belts, pipa-pipa, jsb.). 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) Pangeusi 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 (kayaning film plastik, plastic bottles, medical plastic products, jsb.), and can also be used in radiation-proof plastic products (such as medical protective equipment, nuclear power plant accessories, jsb.).

1.2.2 Classification by Carrier Resin:

According to the type of carrier resin used, filler masterbatch can be divided into polyethylene (PE) pangisi masterbatch, polipropilén (PP) pangisi masterbatch, polyvinyl chloride (PVC) pangisi masterbatch, poliétilén terephthalate (PET) pangisi masterbatch, jsb. The selection of carrier resin is mainly determined by the type of downstream plastic products. Salaku conto, PE filler masterbatch is suitable for PE plastic products (kayaning film plastik, kantong, pipa-pipa); PP filler masterbatch cocog pikeun produk plastik PP (such as woven bags, bagian injection molding, bagian otomotif); Masterbatch pangisi PVC cocog pikeun produk plastik PVC (sapertos pipa PVC, propil, lambaran).

1.2.3 Klasifikasi ku Lapang Aplikasi:

Numutkeun widang aplikasi produk palastik hilir, filler masterbatch bisa dibagi kana film-grade filler masterbatch, injeksi-grade filler masterbatch, masterbatch pangisi kelas ékstrusi, niup molding-grade filler masterbatch, jsb. Masterbatch filler film-grade merlukeun dispersibility alus, fineness tinggi jeung euweuh najis, pikeun mastikeun yén film ditiup teu boga bintik bodas, bintik hideung atanapi pinholes, sareng ngajaga transparansi sareng kateguhan anu saé; masterbatch filler suntik-grade merlukeun fluidity alus sarta ukuran partikel seragam, adaptasi kana prosés suntik molding gancang sarta mastikeun penampilan sarta akurasi dimensi produk suntik; masterbatch filler extrusion-grade merlukeun stabilitas termal alus sarta sipat mékanis, pikeun adaptasi kana suhu luhur sareng prosés ékstrusi tekanan tinggi tina pipa, propil jeung produk lianna.

1.2.4 Klasifikasi ku Jumlah ngeusian:

Numutkeun jumlah keusikan fillers anorganik, masterbatch pangisi tiasa dibagi kana masterbatch anu ngeusian rendah (jumlah ngeusian 30%-50%), masterbatch ngeusian sedeng (jumlah ngeusian 50%-70%) sareng masterbatch anu ngeusian luhur (jumlah ngeusian 70% jeung luhur). Jumlah ngeusian ditangtukeun dumasar kana syarat kinerja produk hilir sareng kapasitas ngolah alat.

2. Téhnologi inti tina Filler Masterbatch Produksi: Téknologi Extrusion Granulation

Téknologi granulasi ékstrusi mangrupikeun téknologi inti produksi masterbatch pangisi, nu integrates Pergaulan, lebur, nyukur, dispersi jeung granulasi. Cai mibanda kaunggulan efisiensi produksi tinggi, kualitas produk alus, adaptability kuat pikeun bahan baku sarta rentang aplikasi lega. Dina produksi filler masterbatch, téhnologi granulation Tonjolan utamana dipaké pikeun ngawujudkeun dispersi seragam of fillers anorganik dina pamawa polimér., ngalembereh jeung plasticize campuran, lajeng extrude na granulate pikeun ngabentuk masterbatch filler granular kalawan ukuran seragam, 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) jeung aditif (such as dispersants, compatibilizers, pelumas, antioxidants, jsb.). The characteristics of these raw materials are quite different, which puts forward special requirements for extrusion equipment:

kahiji, 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. Lamun campur jeung shearing teu cukup, fillers bakal agglomerate, nu teu bisa seragam dispersed dina carrier, hasilna kualitas goréng tina masterbatch filler. Salaku tambahan, karasa tinggi tina fillers anorganik bakal ngabalukarkeun maké serius kana screw jeung tong extruder salila prosés Tonjolan., nu merlukeun screw na laras extruder ngabogaan résistansi maké pisan tinggi.

Kadua, campuran masterbatch filler boga viskositas tinggi na fluidity goréng. Penambahan sajumlah ageung pangisi anorganik bakal ningkatkeun viskositas campuran sacara signifikan, ngurangan fluidity processing, sarta merlukeun extruder ngabogaan kapasitas conveying kuat sarta gaya shearing pikeun mastikeun kamajuan lemes tina lebur, campur jeung extrusion.

katilu, rentang suhu processing sempit. Different carrier resins have different melting points and thermal stability. Salaku conto, 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℃). Ku kituna, 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. Salaku tambahan, 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.

Extruders kembar-screw, di sisi anu sanésna, 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. Salaku tambahan, 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, tekanan, shear force and time. Prinsip kerja khusus sareng aliran prosés nyaéta kieu:

kahiji, pretreatment bahan baku. Bahan baku tina filler masterbatch (inorganic fillers, carrier resin, aditif) perlu pretreated pikeun mastikeun kualitas produk ahir. Léngkah husus ngawengku: 1) Pangobatan garing: Pangeusi anorganik (such as CaCO3, talc) biasana hidrofilik sarta ngandung jumlah nu tangtu Uap. Lamun eusi Uap teuing tinggi, eta bakal mangaruhan pangaruh Pergaulan jeung dispersibility tina bahan, komo ngabalukarkeun gelembung dina masterbatch extruded. Ku kituna, fillers kudu garing dina dryer a (sapertos pengering hawa panas, a dryer vakum) pikeun ngurangan eusi Uap ka handap 0.5%. 2) Crushing jeung sieving: Damar pamawa (such as PE, PP) ditumbuk jadi partikel leutik atawa bubuk jeung ukuran partikel tina 20-40 bolong, nu kondusif pikeun pergaulan seragam jeung fillers jeung aditif. Pangisi anorganik ogé diayak pikeun ngaleungitkeun najis sareng partikel ageung, mastikeun fineness na uniformity of fillers. 3) Premixing: Numutkeun rasio rumus, fillers garing, partikel résin carrier jeung aditif (dispersants, compatibilizers, pelumas, jsb.) diasupkeun kana mixer-speed tinggi pikeun premixing. Laju nyampur sacara umum 800-1200 rpm, jeung waktu campur téh 5-10 menit. Tujuan premixing nyaéta sangkan aditif merata taat kana beungeut fillers na résin carrier, ningkatkeun kasaluyuan antara pangisi sareng pamawa, sareng iklaskeun pondasi pikeun pencampuran ékstrusi salajengna. Dispersant mangrupa aditif konci dina premixing, nu bisa ngabentuk pilem pelindung dina beungeut filler nu, ngurangan énergi permukaan filler nu, nyegah filler ti agglomerating, sarta ngaronjatkeun dispersibility of filler dina résin carrier.

Kadua, dahar jeung conveying. Campuran prémixed dikirim ka hopper dahar tina extruder twin-screw ngaliwatan feeder screw atawa feeder sabuk.. Laju dahar kedah seragam sareng stabil, nu loyog jeung speed screw jeung speed Tonjolan of extruder nu, pikeun mastikeun yén bahan asup kana rongga Tonjolan stably tur ulah akumulasi bahan atawa dahar cukup. Alat dahar extruder biasana dilengkepan fungsi pangaturan laju konversi frékuénsi, nu bisa nyaluyukeun speed dahar nurutkeun kaayaan produksi sabenerna.

katilu, lebur, campur jeung shearing. Bahan-bahan anu asup kana rongga ékstrusi tina extruder sekrup kembar didorong terus-terusan ku sekrup puteran.. Rongga ékstrusi diwangun ku screw sareng tong, sarta volume rongga Tonjolan laun ngurangan sapanjang arah sumbu. Nalika screws muterkeun, bahan anu laun dikomprés handapeun aksi tina screws na tong, sarta tekanan dina rongga Tonjolan laun naek (umumna 3-15MPa). Dina waktos anu sasarengan, bahan anu subjected kana gaya geser kuat sarta gaya gesekan dihasilkeun ku gerakan relatif antara screws na tong., kitu ogé antara hiber screw.

Gaya geser jeung gaya gesekan bisa pinuh megatkeun agglomerates of fillers anorganik, nyieun fillers seragam dispersed dina résin carrier dilebur, sareng ngamajukeun fusi sareng kasaluyuan antara pangisi sareng pamawa. Gaya gesekan ogé bisa ngahasilkeun jumlah panas nu tangtu, 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, jsb.), and the temperature of each section is precisely controlled according to the type of carrier resin and filler. Salaku conto, 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.

Fourth, 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.

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 menit. Cooling gancang bisa nyieun strips solidify gancang, ngajaga bentuk jeung ukuran strips, jeung nyegah deformasi. Sanggeus tiis, strips dikirim ka granulator pikeun motong. granulator dilengkepan péso Rotary, nu bisa motong strips kana granular filler masterbatch kalawan ukuran seragam (ukuran partikel umumna 2-5mm, nu bisa disaluyukeun nurutkeun pangabutuh customer). Laju péso Rotary dicocogkeun sareng laju pangiriman jalur pikeun mastikeun ukuran partikel masterbatch seragam..

Kagenep, screening jeung bungkusan. Masterbatch pangisi granular anu dipotong dikirim ka layar geter pikeun saringan, nu bisa miceun partikel unqualified (sapertos ageung teuing, partikel leutik teuing atawa aglomerated) sarta mastikeun uniformity produk. Masterbatch anu mumpuni teras dikirim ka mesin bungkusan otomatis pikeun bungkusan. Spésifikasi bungkusan tiasa disaluyukeun dumasar kana kabutuhan palanggan (sapertos 25kg / kantong, 50kg/tas), sareng bungkusanna kedah disegel sareng tahan lembab pikeun nyegah masterbatch nyerep Uap sareng mangaruhan kualitas.. Sanggeus bungkusan, produk disimpen dina tempat garing, gudang tiis tur ventilated.

2.3 Faktor konci mangaruhan Filler Masterbatch Extrusion Granulation Pangaruh

Pangaruh granulasi ékstrusi langsung mangaruhan kualitas masterbatch pangisi. Aya seueur faktor anu mangaruhan pangaruh granulasi, utamana kaasup ciri bahan baku, babandingan rumus, pangaruh premixing, parameter ékstrusi jeung struktur sirah paeh. Ngawasaan faktor konci ieu sareng ngadamel panyesuaian ilmiah tiasa mastikeun stabilitas pangaruh granulasi sareng konsistensi kualitas produk..

2.3.1 Ciri Bahan Baku:

Jenisna, ukuran partikel, eusi Uap jeung purity bahan baku boga dampak gede dina pangaruh granulation. Salaku conto, ukuran partikel fillers anorganik langsung mangaruhan dispersibility na fineness of masterbatch nu. The finer ukuran partikel filler (umumna 800-2000 bolong), nu hadé dispersibility, tapi nu leuwih luhur biaya jeung leuwih gampang pikeun aglomerate; beuki kasar ukuran partikel, nu handap ongkos, tapi dispersibility goréng, anu bakal mangaruhan penampilan sareng kinerja masterbatch. Eusi Uap bahan baku (utamana fillers) kudu dikawasa handap 0.5%; lamun eusi Uap teuing tinggi, eta bakal ngabalukarkeun gelembung di masterbatch nu, mangaruhan dénsitas sareng sipat mékanis produk. Kamurnian bahan baku ogé penting pisan; pangotor dina bahan baku (saperti batu, logam, lebu) henteu ngan ukur mangaruhan kualitas masterbatch, tapi ogé ngagem screw jeung tong extruder nu, komo ngabalukarkeun sumbatan alat.

2.3.2 Rasio rumus:

Rasio rumus tina masterbatch pangisi (babandingan filler, résin carrier jeung aditif) mangrupakeun konci pikeun nangtukeun kinerja sarta biaya produk. Jumlah ngeusian pangisi kedah ditangtukeun dumasar kana syarat kinerja produk hilir sareng kapasitas ngolah alat.. Jumlah keusikan teuing tinggi bakal ngakibatkeun dispersibility goréng, kateguhan low jeung fluidity processing goréng tina masterbatch nu; too low filling amount will reduce the cost reduction effect. The type and dosage of additives also need to be reasonably matched. Salaku conto, 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; the dosage is generally 0.5%-2%, which can significantly improve the dispersibility and mechanical properties of the masterbatch. The lubricant is used to reduce the friction between the materials and the screw, barrel and die head, improve the processing fluidity, and prevent the materials from sticking to the equipment; the dosage is generally 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. Laju nyampur sacara umum 800-1200 rpm, the mixing time is 5-10 menit, 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 ka 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. Sanajan kitu, 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. Laju screw kedah disaluyukeun dumasar kana jumlah ngeusian sareng jinis pangisi masterbatch-pikeun masterbatch anu ngeusian tinggi, a speed screw luhur diperlukeun pikeun mastikeun shearing cukup tur Pergaulan.
• Suhu Extrusion: Suhu ékstrusi dibagi kana sababaraha bagian (feeding section, melting section, mixing section, homogenizing section, bagian sirah maot), sareng suhu unggal bagian kedah dikontrol sacara tepat dumasar kana jinis résin pamawa sareng pangisi. Suhu bagian tuang langkung handap (rada luhur ti titik lebur résin carrier), nu utamana pikeun nyegah bahan ti caking sarta mastikeun dahar lemes; suhu bagian lebur sedeng, nu utamana pikeun ngamajukeun lebur na plasticization tina résin carrier; suhu bagian Pergaulan leuwih luhur, 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. Sanajan kitu, if the pressure is too high, eta bakal ngaronjatkeun konsumsi énergi jeung maké pakakas, komo ngabalukarkeun sirah paeh meungpeuk; lamun tekanan teuing low, bahan teu bisa pinuh dikomprés sarta dicampur, partikel masterbatch leupas, jeung kinerja teu stabil.

2.3.5 Maot Struktur Kepala:

Struktur sirah paeh utamana ngawengku jumlah, bentuk jeung ukuran liang paeh. Bentuk liang paeh nangtukeun bentuk cross-sectional tina strips extruded (saperti sirkular, pasagi), jeung ukuran liang paeh nangtukeun diaméter awal strips jeung ukuran partikel ahir masterbatch nu. Leuwih leutik ukuran liang paeh, nu leuwih gede tekanan extrusion, nu hadé pangaruh campur jeung dispersing, tapi kapasitas produksina bakal ngurangan; nu leuwih gede ukuran liang paeh, nu handap tekanan extrusion, nu handap efisiensi produksi, tapi ukuran partikel masterbatch leuwih badag. Jumlah liang paeh mangaruhan kapasitas produksi; beuki jumlah maot liang, nu leuwih luhur kapasitas produksi, tapi perlu pikeun mastikeun yén sebaran tekanan téh seragam, ku kituna pikeun nyingkahan ketebalan henteu rata tina strips sarta ukuran partikel henteu rata masterbatch nu.

3. Extruders kami: Kaunggulan jeung Series Produk pikeun Filler Masterbatch Produksi

Kami geus lila kalibet dina panalungtikan, ngembangkeun sarta produksi extruders-kinerja tinggi na garis produksi granulation, sarta geus akumulasi pangalaman euyeub dina widang ngolah masterbatch filler. Numutkeun karakteristik bahan baku masterbatch filler (karasa tinggi, kasaluyuan goréng, viskositas tinggi) jeung syarat ngolah (dispersibility alus, 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, precise temperature control, stable performance and low operating cost, which can meet the processing needs of various types, different filling amounts of filler masterbatch (CaCO3, talc, BaSO4, jsb.), 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 (such as 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. Salaku tambahan, 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, issue a detailed wear report, 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, kalawan pitch screw lumrah, lead and compression ratio design. 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, nyieun fillers seragam dispersed dina résin carrier dilebur, and ensure the dispersibility of the masterbatch. The screw is designed with a modular structure, and different screw elements (such as conveying elements, mixing elements, 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. Salaku conto, 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 Kontrol Suhu anu tepat, 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, the system will issue an alarm prompt in time, and even automatically adjust the heating power or shut down the equipment if necessary, to avoid equipment failure and product quality problems. Salaku tambahan, 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 Wide Application Range, Strong Flexibility:

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 (kayaning film plastik, 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 (such as automotive parts, 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 (above 1250 bolong) 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: kahiji, dry the base plastic particles and filler masterbatch to remove moisture (the moisture content should be controlled below 0.5%); then, 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 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. Ku kituna, 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 (such as temperature, tekanan, speed 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. Salaku conto, 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%. Salaku conto, 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: Pangisi masterbatch (especially calcium carbonate, talc masterbatch) is easy to absorb moisture, which will cause bubbles, pinholes and other defects in the final product. Ku kituna, the masterbatch should be stored in a dry, gudang tiis tur ventilated, and should be dried before use (the drying temperature is 80-100℃, and the drying time is 2-4 jam).
• Compatibility: The carrier resin of the filler masterbatch should be consistent with or compatible with the base plastic of the product. Salaku conto, 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, nyababkeun cacad sapertos bintik bodas, 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 (umumna 6-12 bulan). If the storage period is exceeded, the masterbatch may absorb moisture, agglomerate or the performance of additives may degrade, affecting the use effect. Ku kituna, the masterbatch should be used within the storage period.

Causes: 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) The processing temperature is too low, and the carrier resin is not fully melted, which affects the dispersion of the filler.

Solutions: 1) Select inorganic fillers with fine and uniform particle size (umumna 800-2000 bolong), and sieve the fillers before use to remove large particles and agglomerates; 2) Increase the dosage of dispersant appropriately (within the range of 1%-3% of the filler dosage) or replace with a dispersant compatible with the filler and carrier resin; 3) Optimize the premixing process, increase the mixing speed (800-1200 rpm) and mixing time (5-10 menit), and control the mixing temperature at 40-60℃ to improve the premixing uniformity; 4) Adjust the screw structure of the extruder, increase the number of shearing elements, or increase the screw speed to enhance the shear force; 5) Appropriately increase the processing temperature of the extruder to ensure that the carrier resin is fully melted, 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.

Causes: 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.

Solutions: 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.

Causes:

• 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);
• The processing temperature is too low, and the carrier resin is not fully melted;
• The dosage of lubricant is insufficient, which increases the friction between the materials and affects the fluidity.

Solutions:

• Reduce the filling amount of the filler appropriately, or select a filler with better dispersibility to improve the fluidity;
• Replace the carrier resin with a higher melting index (salaku conto, use PE carrier resin with a melting index of 2-5g/10min for PE filler masterbatch);
• Appropriately increase the processing temperature of the extruder to ensure that the carrier resin is fully melted, improving the fluidity of the masterbatch;
• Increase the dosage of lubricant appropriately (within the range of 0.3%-1%), reduce the friction between the materials, and improve the fluidity.

5.1.4 Yellowing of Filler Masterbatch

The main manifestations are: the color of the masterbatch turns yellow, which affects the appearance of the final plastic product (especially light-colored products).

Causes:

• The thermal stability of the carrier resin is poor, and thermal decomposition occurs at high processing temperatures;
• The additives (such as dispersants, pelumas) are decomposed at high temperatures, producing yellow substances;
• The processing temperature is too high, leading to the oxidation and yellowing of the masterbatch;
• The filler contains impurities (such as iron oxide), which causes the masterbatch to turn yellow.

Solutions:

• Select carrier resin with good thermal stability (such as adding antioxidants to the carrier resin);
• Replace additives with good thermal stability, avoid using additives that are easy to decompose at high temperatures;
• Reduce the processing temperature appropriately, avoid the oxidation and decomposition of the masterbatch;
• Screen the filler before use, remove impurities, and select fillers with high purity (such as calcium carbonate with a whiteness of ≥93).

5.1.5 High Moisture Content of Filler Masterbatch

The main manifestations are: gelembung, pinholes and other defects appear in the final plastic product after the masterbatch is mixed with the base plastic.

Causes:

• The filler is not dried thoroughly, and the moisture content exceeds 0.5%;
• The carrier resin or additives contain moisture;
• The masterbatch absorbs moisture during storage (stored in a humid environment);
• The premixing process is carried out in a humid environment, and the materials absorb moisture.

Solutions:

• Extend the drying time of the filler (drying temperature 80-100℃, drying time 3-5 jam), and detect the moisture content of the filler to ensure that it is below 0.5%;
• Dry the carrier resin and additives before use to remove moisture;
• Store the masterbatch in a dry, gudang tiis tur ventilated, and seal the packaging to prevent moisture absorption;
• Carry out the premixing process in a dry environment, and avoid the materials absorbing moisture from the air.

5.2 Common Production Equipment Problems and Their Solutions
