1. Overview of Filler Masterbatch Industry and Product Characteristics

1.1 Current Situation and Development Trend of Filler Masterbatch Industry

Ing taun-taun pungkasan, didorong dening perkembangan cepet saka industri hilir kayata packaging, konstruksi, 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 lan granulating pangisi anorganik (kayata kalsium karbonat, talc, barium sulfat, lsp.) karo pembawa polimer (kayata poliethelin, polipropilena, polivinil klorida, lsp.) lan aditif sing cocog (kayata dispersants, kompatibilitas, pelumas, lsp.) ing babagan tartamtu. Fungsi inti yaiku nyuda biaya produksi produk plastik nalika nambah utawa njaga kinerja dhasar produk plastik.

Miturut statistik data sing cocog, ukuran pasar masterbatch pangisi global wis ngluwihi 20 milyar dolar AS, lan samesthine kanggo njaga tingkat wutah saka 6%-9% ing sawetara taun sabanjuré. Antarane wong-wong mau, kalsium karbonat (CaCO3) masterbatch pangisi minangka jinis produk sing paling akeh digunakake, accounting kanggo luwih saka 60% saka total pasar masterbatch pengisi, ngiring dening masterbatch ngisi talc, barium sulfat (BaSO4) masterbatch pengisi lan masterbatch pengisi khusus liyane. Wilayah Asia-Pasifik minangka pasar produksi lan konsumsi masterbatch pengisi paling gedhe ing donya, accounting kanggo luwih saka 50% saka pangsa pasar global, kang utamané amarga pembangunan cepet saka industri Processing plastik ing China, India lan negara liyane, panjaluk gedhe kanggo nyuda biaya lan perbaikan kinerja produk plastik, lan dandan terus-terusan saka kapasitas ndhukung industri.

Tren pangembangan industri masterbatch pengisi utamane dibayangke ing papat aspek: dhisik, kinerja dhuwur lan functionalization. Kanthi nganyarke syarat produk plastik hilir, masterbatch pangisi ora diwatesi maneh kanggo nyuda biaya, nanging mboko sithik berkembang menyang functionalization, kayata ningkatake kaku, kateguhan, tahan panas, tahan cuaca lan sifat penghalang produk plastik, lan ngembangake masterbatches pengisi fungsional khusus kayata flame retardant, antistatik lan antibakteri; kapindho, jumlah Isi dhuwur lan dispersibility apik. Ing premis kanggo njamin 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; katelu, environmental protection and low pollution. Kanthi nguatake kabijakan perlindungan lingkungan global lan ningkatake kesadaran perlindungan lingkungan, 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; kaping papat, intelligence and efficiency of production equipment. Supaya bisa ketemu gedhe-gedhe, kabutuhan produksi terus-terusan lan kualitas masterbatch pangisi, manufaktur terus-terusan ngenalake garis produksi granulasi lan sistem kontrol cerdas, ningkatake efisiensi produksi, nyuda biaya tenaga kerja lan njamin stabilitas kualitas produk.

Marang latar mburi iki, teknologi granulasi ekstrusi, minangka teknologi inti produksi masterbatch pengisi, wis dadi kunci kanggo nemtokake kualitas masterbatch pengisi lan daya saing perusahaan. Kinerja extruders langsung mengaruhi dispersibility, wangun partikel, indeks leleh lan indikator utama masterbatch pengisi liyane. Extruders profesional lan jalur produksi granulasi kanggo masterbatch pengisi dikembangake kanggo nanggepi karakteristik industri lan permintaan pasar., which can effectively solve the pain points in filler masterbatch processing (such as poor dispersibility, uneven particle size, low filling amount, konsumsi energi dhuwur, lsp.) 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, resin pembawa, 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 Classification by Filler Type:

This is the most common classification method for filler masterbatch. According to the type of inorganic filler, it can be mainly divided into calcium carbonate (CaCO3) masterbatch pangisi, talc filler masterbatch, barium sulfat (BaSO4) masterbatch pangisi, lan masterbatches pangisi khusus liyane (kayata masterbatch pengisi kaolin, masterbatch pangisi karbon ireng, masterbatch pengisi serat kaca, lsp.).

• Kalsium Karbonat (CaCO3) Pengisi Masterbatch: Iki minangka masterbatch pengisi sing paling akeh digunakake kanthi biaya paling murah. Pangisi utamane kalsium karbonat entheng utawa kalsium karbonat abot. Kalsium karbonat entheng nduweni ukuran partikel sing alus, dispersibility apik lan whiteness dhuwur, kang cocok kanggo produk plastik karo syarat dhuwur ing katon lan fineness (kayata film plastik, produk injection molding); kalsium karbonat abot nduweni atose dhuwur, resistance nyandhang apik lan rega murah, kang cocok kanggo produk plastik karo syarat dhuwur ing rigidity lan kontrol biaya (kayata tas anyaman, sabuk packaging, pipa, lsp.). Masterbatch pengisi kalsium karbonat ora mung bisa nyuda biaya produksi, nanging uga nambah rigidity, tahan panas lan stabilitas dimensi produk plastik, lan nduweni efek lubricating tartamtu, kang bisa nambah fluidity Processing saka plastik.
• Talc Filler Masterbatch: Pengisi yaiku bubuk talc kanthi struktur berlapis. Bubuk talc nduweni sifat mekanik sing apik, tahan panas lan stabilitas kimia. Masterbatch pengisi talc utamane digunakake ing polipropilena (PP) produk plastik, kang Ngartekno bisa nambah rigidity ing, suhu distorsi panas lan kekuatan impact saka produk PP, lan digunakake digunakake ing bagean otomotif, cangkang piranti omah, pipa plastik lan lapangan liyane sing mbutuhake kinerja dhuwur.
• Barium Sulfat (BaSO4) Pengisi Masterbatch: Pangisi yaiku bubuk barium sulfat, kang nduweni keputihan dhuwur, transparansi apik, inertness kimia lan resistance radiation. Masterbatch pengisi barium sulfat cocog kanggo produk plastik kanthi syarat transparansi sing dhuwur, whiteness lan stabilitas kimia (kayata film plastik, gendul plastik, produk plastik medis, lsp.), lan uga bisa digunakake ing produk plastik radiation-bukti (kayata alat pelindung medis, aksesoris pembangkit listrik tenaga nuklir, lsp.).

1.2.2 Klasifikasi miturut Resin Carrier:

Miturut jinis resin operator digunakake, masterbatch pangisi bisa dipérang dadi poliethelin (PE) masterbatch pangisi, polipropilena (PP) masterbatch pangisi, polivinil klorida (PVC) masterbatch pangisi, polyethylene terephthalate (PET) masterbatch pangisi, lsp. Pilihan resin operator utamane ditemtokake dening jinis produk plastik hilir. Contone, Masterbatch pengisi PE cocok kanggo produk plastik PE (kayata film plastik, tas, pipa); PP filler masterbatch cocok kanggo produk plastik PP (kayata tas anyaman, bagean ngecor injeksi, bagean otomotif); Masterbatch pangisi PVC cocok kanggo produk plastik PVC (kayata pipa PVC, profil, lembaran).

1.2.3 Klasifikasi miturut Bidang Aplikasi:

Miturut lapangan aplikasi produk plastik hilir, masterbatch pengisi bisa dipérang dadi masterbatch pengisi kelas film, masterbatch pengisi kelas injeksi, masterbatch pengisi kelas ekstrusi, jotosan ngecor-bahan pangisi masterbatch, lsp. Masterbatch pengisi kelas film mbutuhake dispersibilitas sing apik, fineness dhuwur lan ora impurities, kanggo mesthekake yen film sing diunekake ora ana bintik putih, bintik ireng utawa pinholes, lan njaga transparansi lan kateguhan sing apik; masterbatch pangisi kelas injeksi mbutuhake fluiditas sing apik lan ukuran partikel sing seragam, kanggo adaptasi karo proses ngecor injeksi kanthi cepet lan mesthekake tampilan lan akurasi dimensi produk injeksi; masterbatch pengisi kelas ekstrusi mbutuhake stabilitas termal lan sifat mekanik sing apik, kanggo ngganti menyang suhu dhuwur lan proses extrusion tekanan dhuwur saka pipo, profil lan produk liyane.

1.2.4 Klasifikasi miturut Jumlah Isi:

Miturut jumlah ngisi pangisi anorganik, masterbatch pangisi bisa dipérang dadi masterbatch sing kurang diisi (jumlah ngisi 30%-50%), masterbatch ngisi medium (jumlah ngisi 50%-70%) lan masterbatch ngisi dhuwur (jumlah ngisi 70% lan ndhuwur). Jumlah ngisi ditemtokake miturut syarat kinerja produk hilir lan kapasitas pangolahan peralatan. Masterbatch sing diisi kanthi dhuwur duwe efek nyuda biaya sing luwih jelas, nanging nduweni syarat sing luwih dhuwur babagan dispersibilitas pengisi lan kinerja extruders-mung extruders kinerja dhuwur bisa njamin pencampuran seragam lan leleh bahan ngisi dhuwur., ngindhari aglomerasi lan fluiditas pangolahan sing kurang.

Wigati dicathet yen indikator kinerja inti masterbatch pengisi utamane kalebu dispersibilitas, keseragaman ukuran partikel, indeks leleh, keputihan (kanggo produk werna cahya) lan kompatibilitas karo resin operator. Antarane wong-wong mau, dispersibilitas minangka indikator sing paling kritis-dispersibilitas sing ora apik bakal nyebabake distribusi pangisi sing ora rata ing produk plastik., nyebabake cacat kayata bintik putih, bintik ireng, aglomerasi lan produk rapuh, sing akeh mengaruhi tampilan lan kinerja produk plastik. Mulane, pilihan peralatan ekstrusi majeng lan teknologi pangolahan ilmiah iku penting kanggo njamin dispersibility lan kualitas sakabèhé saka masterbatch pangisi.

2. Teknologi Inti Produksi Masterbatch Pengisi: Teknologi Granulasi Ekstrusi

Teknologi granulasi ekstrusi minangka teknologi inti produksi masterbatch pengisi, kang nyawiji campuran, lebur, nyukur, dispersi lan granulasi. Wis kaluwihan saka efficiency produksi dhuwur, kualitas produk apik, daya adaptasi kuwat kanggo bahan mentahan lan sawetara aplikasi sudhut. Ing produksi masterbatch pengisi, teknologi granulasi extrusion utamané dipigunakaké kanggo éling sawur seragam saka pangisi anorganik ing operator polimer, nyawiji lan plasticize dicampur, banjur extrude lan granulate kanggo mbentuk masterbatch pangisi granular kanthi ukuran seragam, fluidity apik lan kinerja stabil. Kualitas granulasi ekstrusi langsung nemtokake indikator kinerja utama masterbatch pengisi, kayata dispersibility, ukuran partikel lan indeks leleh.

2.1 Karakteristik Bahan Baku Pengisi Masterbatch lan Keperluan kanggo Peralatan Ekstrusi

Bahan mentah masterbatch pengisi utamane kalebu telung bagean: pangisi anorganik (kayata CaCO3, talc, BaSO4), pembawa polimer (kayata PE, PP, PVC) lan aditif (kayata dispersants, kompatibilitas, pelumas, antioksidan, lsp.). Karakteristik bahan mentah kasebut cukup beda, kang sijine nerusake syarat khusus kanggo peralatan extrusion:

Pisanan, pangisi anorganik duwe atose dhuwur, kompatibilitas miskin karo operator polimer, lan gampang agglomerate. Paling pengisi anorganik (kayata CaCO3, talc) iku hidrofilik, dene pembawa polimer iku hidrofobik, kang ndadékaké kanggo kompatibilitas miskin antarane pangisi lan operator. Yen nyampur lan nyukur ora cukup, pangisi bakal agglomerate, kang ora bisa seragam buyar ing operator, nyebabake kualitas masterbatch pengisi sing kurang apik. Kajaba iku, atose dhuwur saka pangisi anorganik bakal nimbulaké nyandhang serius kanggo meneng lan tong minyak extruder sak proses extrusion, sing mbutuhake meneng lan tong minyak extruder duwe resistance nyandhang dhuwur banget.

Kapindho, campuran masterbatch pangisi nduweni viskositas dhuwur lan fluiditas sing kurang. Penambahan akeh pengisi anorganik bakal nambah viskositas campuran, nyuda fluiditas pangolahan, lan mbutuhake extruder duwe kapasitas ngirim kuwat lan pasukan shearing kanggo mesthekake kemajuan Gamelan saka leleh, nyawiji lan extrusion.

Katelu, sawetara suhu Processing sempit. Resin pembawa beda duwe titik leleh lan stabilitas termal sing beda. Contone, titik leleh PE yaiku 100-130 ℃, titik leleh saka PP punika 160-170 ℃, lan PVC gampang decompose ing suhu dhuwur (ndhuwur 160 ℃). Mulane, peralatan ekstrusi kudu duwe kapasitas kontrol suhu sing tepat kanggo mesthekake yen campuran wis ilang kanthi lengkap tanpa dekomposisi termal, lan supaya dekomposisi aditif lan rusak kinerja produk.

Based on the above characteristics, single-screw extruders are not suitable for large-scale and high-quality production of filler masterbatch. Amarga extruder siji-screw duwe sawetara geser sing sempit, kapasitas pumping miskin lan ora ana efek reresik dhewe. When processing high-viscosity and high-filler mixtures, iku gampang kanggo nimbulaké akumulasi materi, blockage lan campuran ora rata ing tong minyak extruder, resulting in poor dispersibility of filler masterbatch, uneven particle size and unstable product quality. Kajaba iku, 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-meneng extruders, ing sisih liyane, duwe kaluwihan sing jelas ing produksi masterbatch pengisi lan wis dadi peralatan utama kanggo granulasi ekstrusi masterbatch pengisi.. Extruders twin-screw duwe sawetara geser luwih akeh, efek pumping luwih efektif lan efek self-cleaning, sing bisa ngatasi masalah kompatibilitas sing kurang apik, aglomerasi gampang lan fluiditas sing kurang saka bahan mentah masterbatch pengisi. Intermeshing lan puteran saka ngawut-awut kembar bisa generate pasukan geser kuwat lan pasukan kneading, sing bisa ngilangi aglomerat pengisi anorganik kanthi lengkap, nggawe pangisi seragam disebarake ing operator polimer, lan njamin dispersibility lan stabilitas prodhuk. Kajaba iku, kembar-meneng extruder nduweni akurasi kontrol suhu apik, adaptasi kuwat kanggo bahan mentahan, lan bisa adaptasi karo pangolahan macem-macem jinis, jumlah ngisi beda masterbatch pangisi, lan nduweni efisiensi produksi dhuwur lan konsumsi energi sing kurang.

2.2 Prinsip Kerja Granulasi Ekstrusi Masterbatch Filler

Proses granulasi ekstrusi masterbatch pengisi minangka proses fisik lan kimia sing kompleks, sing melu interaksi sawetara faktor kayata suhu, tekanan, gaya geser lan wektu. Prinsip kerja tartamtu lan aliran proses kaya ing ngisor iki:

Pisanan, pretreatment bahan baku. Bahan baku pengisi masterbatch (pangisi anorganik, resin pembawa, aditif) kudu pretreated kanggo njamin kualitas produk pungkasan. Langkah-langkah tartamtu kalebu: 1) Pangobatan pangatusan: Pangisi anorganik (kayata CaCO3, talc) biasane hidrofilik lan ngemot jumlah kelembapan tartamtu. Yen isi Kelembapan dhuwur banget, bakal mengaruhi efek nyawiji lan dispersibility saka bahan, lan malah nimbulaké umpluk ing masterbatch extruded. Mulane, pangisi kudu garing ing dryer (kayata pengering hawa panas, pengering vakum) kanggo nyuda isi Kelembapan ing ngisor 0.5%. 2) Crushing lan sieving: Resin pembawa (kayata PE, PP) diremuk dadi partikel cilik utawa bubuk kanthi ukuran partikel 20-40 bolong, sing kondusif kanggo nyampur seragam karo pangisi lan aditif. Pengisi anorganik uga disaring kanggo mbusak impurities lan partikel gedhe, njamin kehalusan lan keseragaman pengisi. 3) Premixing: Miturut rasio rumus, pangisi garing, partikel resin carrier lan aditif (dispersants, kompatibilitas, pelumas, lsp.) dilebokake ing mixer kacepetan dhuwur kanggo premixing. Kacepetan nyawiji umume 800-1200 rpm, lan wektu nyampur yaiku 5-10 menit. Tujuan premixing yaiku kanggo nggawe aditif kanthi rata ing permukaan pengisi lan resin operator, nambah kompatibilitas antarane pangisi lan operator, lan lay pondasi kanggo campuran extrusion sakteruse. Dispersant minangka aditif utama ing premixing, sing bisa mbentuk film protèktif ing permukaan pengisi, reduce the surface energy of the filler, prevent the filler from agglomerating, and improve the dispersibility of the filler in the carrier resin.

Kapindho, feeding and conveying. Campuran sing wis dicampur dikirim menyang hopper pakan saka extruder sekrup kembar liwat feeder sekrup utawa feeder sabuk.. 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. Piranti pakan saka extruder biasane dilengkapi fungsi regulasi kacepetan konversi frekuensi, which can adjust the feeding speed according to the actual production situation.

Katelu, lebur, nyampur lan nyukur. Bahan sing mlebu rongga ekstrusi saka extruder sekrup kembar didorong terus-terusan kanthi sekrup puteran. Rongga ekstrusi kasusun saka sekrup lan tong minyak, lan volume rongga ekstrusi mboko sithik mudhun ing arah sumbu. Nalika ngawut-awut muter, bahan sing mboko sithik teken ing tumindak ngawut-awut lan tong minyak, lan tekanan ing rongga ekstrusi mboko sithik mundhak (umume 3-15MPa). Ing wektu sing padha, bahan kasebut kena pengaruh gaya geser lan gaya gesekan sing ditimbulake dening gerakan relatif antarane sekrup lan tong minyak., uga antarane flights meneng.

Gaya geser lan gaya gesekan bisa ngilangi aglomerat pengisi anorganik, nggawe pangisi seragam kasebar ing resin operator ilang, lan ningkataké fusi lan kompatibilitas antarane pangisi lan operator. Gaya gesekan uga bisa ngasilake panas tartamtu, sing digabungake karo pemanasan eksternal tong minyak (pemanasan listrik utawa pemanasan uap) kanggo nggawe resin operator mboko sithik nyawiji lan plasticize. Laras extruder biasane dipérang dadi 3-6 bagean kontrol suhu (bagean dipakani, bagean leleh, bagean nyawiji, bagean homogenizing, lsp.), and the temperature of each section is precisely controlled according to the type of carrier resin and filler. Contone, 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.

Kaping papat, extrusion and shaping. Ing lengkap nyawiji, materi campuran lan buyar wis di-push menyang sirah die saka extruder dening ngawut-awut. The die head is equipped with multiple die holes (nomer lan ukuran bolongan mati ditemtokake miturut ukuran partikel masterbatch), and the material is extruded from the die holes at a high speed to form continuous strips of uniform thickness. Suhu sirah die rada luwih murah tinimbang bagean homogenizing, which can prevent the material from decomposing due to excessive temperature and ensure the shaping effect of the strips.

kaping lima, 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℃, lan wektu cooling punika 2-5 menit. Rapid cooling can make the strips solidify quickly, maintain the shape and size of the strips, and avoid deformation. Sawise adhem, 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, kang bisa diatur miturut kabutuhan customer). 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 lan packaging. The cut granular filler masterbatch is sent to a vibrating screen for screening, which can remove unqualified particles (kayata gedhe banget, 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), and the packaging should be sealed and moisture-proof to prevent the masterbatch from absorbing moisture and affecting the quality. After packaging, the products are stored in a dry, gudang kelangan lan ventilated.

2.3 Key Factors Affecting Filler Masterbatch Extrusion Granulation Effect

The effect of extrusion granulation directly affects the quality of filler masterbatch. There are many factors affecting the granulation effect, utamane kalebu karakteristik bahan mentah, rasio rumus, efek premixing, paramèter ekstrusi lan struktur sirah mati. 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 Karakteristik Bahan Baku:

Jinis, ukuran partikel, moisture content and purity of raw materials have a great impact on the granulation effect. Contone, the particle size of inorganic fillers directly affects the dispersibility and fineness of the masterbatch. The finer the particle size of the filler (umume 800-2000 bolong), 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%; yen isi kelembapan dhuwur banget, it will cause bubbles in the masterbatch, mengaruhi Kapadhetan lan sifat mekanik prodhuk. Kemurnian bahan mentah uga penting banget; impurities ing bahan mentahan (kayata watu, logam, bledug) ora mung bakal mengaruhi kualitas masterbatch, nanging uga nganggo meneng lan tong minyak extruder, lan malah njalari macet peralatan.

2.3.2 Rasio Formula:

Rasio formula masterbatch pengisi (rasio pangisi, resin carrier lan aditif) minangka kunci kanggo nemtokake kinerja lan biaya produk. Jumlah ngisi pangisi kudu ditemtokake miturut syarat kinerja produk hilir lan kapasitas pangolahan peralatan.. Jumlah ngisi sing dhuwur banget bakal nyebabake dispersibilitas sing ora apik, kateguhan kurang lan fluidity Processing miskin saka masterbatch; jumlah pangisi sing sithik banget bakal nyuda efek nyuda biaya. Jinis lan dosis aditif uga kudu cocog. Contone, dosis dispersant umume 1%-3% saka dosis pangisi; 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, wektu nyawiji lan suhu nyawiji. Kacepetan nyawiji umume 800-1200 rpm, wektu nyampur yaiku 5-10 menit, lan suhu nyawiji dikontrol ing 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.

• Kacepetan meneng: The screw speed generally ranges from 150 kanggo 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. Nanging, yen kacepetan meneng dhuwur banget, wektu panggonan saka bahan ing growong extrusion cendhak banget, resulting in incomplete melting of the carrier resin, insufficient mixing of the materials, and uneven particle size of the masterbatch; yen kacepetan meneng banget kurang, gaya geser lan gaya gesekan ora cukup, the filler cannot be fully dispersed, lan efisiensi produksi kurang. 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.
• Suhu Ekstrusi: The extrusion temperature is divided into multiple sections (bagean dipakani, bagean leleh, bagean nyawiji, bagean homogenizing, bagean sirah mati), 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.
• Tekanan Ekstrusi: The extrusion pressure is generally 3-15MPa. The pressure in the extrusion cavity is mainly determined by the compression ratio of the screw, ukuran bolongan die lan kacepetan meneng. Sing luwih dhuwur tekanan ekstrusi, the better the mixing and dispersing effect of the materials, and the denser the masterbatch particles. Nanging, yen meksa dhuwur banget, bakal nambah konsumsi energi lan nyandhang peralatan, lan malah nyebabake sirah die kanggo mblokir; yen meksa banget kurang, materi ora bisa kanthi teken lan pipis, the masterbatch particles are loose, lan kinerja ora stabil.

2.3.5 Struktur Kepala Die:

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, luwih dhuwur kapasitas produksi, nanging perlu kanggo mesthekake yen distribusi tekanan seragam, so as to avoid uneven thickness of the strips and uneven particle size of the masterbatch.

3. Extruders kita: Advantages and Product Series for Filler Masterbatch Production

Kita wis suwe melu riset, development and production of high-performance extruders and granulation production lines, and have accumulated rich experience in the field of filler masterbatch processing. According to the characteristics of filler masterbatch raw materials (high hardness, poor compatibility, viskositas dhuwur) lan syarat pangolahan (good dispersibility, uniform particle size, high filling amount), we have developed a series of twin-screw extruders specially suitable for filler masterbatch production. Our extruders have the advantages of high wear resistance, strong shearing force, kontrol suhu sing tepat, stable performance and low operating cost, which can meet the processing needs of various types, jumlah ngisi beda masterbatch pangisi (CaCO3, talc, BaSO4, lsp.), 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 Dhuwur Wear Resistance, Long Service Life:

Aiming at the problem that inorganic fillers (kayata 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 (kayata 38CrMoAlA), and after nitriding treatment or bimetallic composite treatment, the surface hardness can reach ≥65 HRC, kang nduweni resistance nyandhang banget kuwat lan resistance karat, and can effectively resist the wear caused by the friction between the high-hardness filler and the components. Iki banget ngluwihi umur layanan saka meneng lan tong minyak, reduces the frequency of component replacement, and reduces the maintenance cost of the equipment. Kajaba iku, 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, karo pitch meneng cukup, lead and compression ratio design. Intermeshing lan puteran saka ngawut-awut kembar bisa generate pasukan geser kuwat lan pasukan kneading, sing bisa ngilangi aglomerat pengisi anorganik kanthi lengkap, nggawe pangisi seragam kasebar ing resin operator ilang, and ensure the dispersibility of the masterbatch. The screw is designed with a modular structure, and different screw elements (kayata ngaturake unsur, unsur campuran, unsur nyukur) 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. Contone, 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 Precise Temperature Control, 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.

In the production process of filler masterbatch, amarga pengaruh bahan mentah, formula, processing equipment and processing parameters, various problems may occur, which affect the quality and production efficiency of the masterbatch. This chapter will summarize the common problems in filler masterbatch production, nganalisa penyebabe, and put forward targeted solutions to help enterprises solve production pain points and improve product quality stability.

5.1 Common Quality Problems of Filler Masterbatch and Their Solutions

5.1.1 Poor Dispersibility of Filler 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.

Nimbulaké: 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.

Solusi: 1) Select inorganic fillers with fine and uniform particle size (umume 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% saka dosis pangisi) or replace with a dispersant compatible with the filler and carrier resin; 3) Ngoptimalake proses premixing, nambah kacepetan nyawiji (800-1200 rpm) lan wektu nyampur (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.

Nimbulaké: 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.

Solusi: 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.

Nimbulaké:

• 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.

Solusi:

• 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 (contone, 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).

Nimbulaké:

• The thermal stability of the carrier resin is poor, and thermal decomposition occurs at high processing temperatures;
• The additives (kayata 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.

Solusi:

• 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.

Nimbulaké:

• 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.

Solusi:

• 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 kelangan lan ventilated, and seal the packaging to prevent moisture absorption;
