No laila, the raw materials must be dried before processing. The drying temperature and time are determined according to the type of raw material: ʻo kahi laʻana, organic pigments are dried at 60-80℃ for 2-4 hola, PE/PP carriers are dried at 80-100℃ for 3-5 hola, and PA carriers are dried at 100-120℃ for 6-8 hola. The moisture content of the dried raw materials should be controlled below 0.1%.
• Crushing and Sieving: For pigments with large particle size (such as titanium dioxide agglomerates) and carriers with uneven particle size, crushing and sieving treatment should be carried out to ensure the uniformity of raw materials. The particle size of the crushed raw materials should be controlled at 20-40 makaʻu, which is conducive to the uniform mixing of raw materials and the breaking of pigment agglomerates during extrusion.

I ka manawa like, Hoʻopili ʻia nā mea waiwai i ka ikaika ʻoki ikaika a me ka ikaika friction i hana ʻia e ka neʻe pili ʻana ma waena o nā wili a me ka barela., a ma waena o nā lele wili. Hiki i ka ikaika shear a me ka friction ikaika ke uhai loa i nā agglomerates o nā puaʻa, e hoʻopuehu like i nā puaʻa i loko o ka mea lawe hehee, a hoʻoikaika i ka hui ʻana a me ka launa pū ʻana ma waena o ka puaʻa, mea lawe a me nā mea hoʻohui. Hiki nō hoʻi i ka ikaika friction ke hoʻoulu i kekahi nui o ka wela, i hui pu ia me ka wela o waho o ka barela (ka hoʻomehana uila a i ʻole ka hoʻomehana mahu) e hoʻoheheʻe mālie a hoʻoheheʻe ʻia ka mea lawe.

Hoʻokaʻawale pinepine ʻia ka pahu o ka extruder i 4-6 ʻāpana hoʻomalu mahana (ʻāpana hānai, pauku hehee, ʻāpana hui ʻana, ʻāpana homogenizing, pauku poʻo make), a ʻo ka mahana o kēlā me kēia ʻāpana e hoʻomalu pono ʻia e like me ke ʻano o ka masterbatch (ʻano lawe lawe, ʻano puaʻa). ʻo kahi laʻana, i ka hana ʻana i ka masterbatch PE, ʻO ka mahana o ka ʻāpana hānai he 100-120 ℃, ʻO ka māhele hoʻoheheʻe he 160-180 ℃, ʻO ka ʻāpana hui ʻana he 170-190 ℃, ʻO ka māhele homogenizing he 160-180 ℃, a ʻo ka ʻāpana poʻo make he 150-170 ℃. Hiki i ka mana wela kūpono ke hōʻoia i ka hoʻoheheʻe piha ʻana o ka mea lawe me ka ʻole o ka decomposition thermal, a ʻaʻole ʻeleʻele nā ​​puaʻa.

2.2.5 Extrusion a me ka hoʻohua

Ka hehee loa, hoʻokuʻu ʻia nā mea i hui pū ʻia a hoʻopuehu ʻia i ke poʻo make o ka extruder e nā wili. Hoʻolako pinepine ʻia ke poʻo make o ka masterbatch extruder me nā puka make pōʻai he nui (Hoʻoholo ʻia ka helu a me ka nui o nā lua make e like me ka nui o ka nui o ka masterbatch). Hoʻokuʻu ʻia ka mea mai ke poʻo make i ka wikiwiki kiʻekiʻe e hana i nā huahana semi-finished hoʻomau (the diameter of the strip is usually 2-5mm, which can be adjusted according to customer needs).

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 strip. The extrusion speed is controlled according to the type of masterbatch and the particle size requirement, generally ranging from 1-3m/min. The extrusion pressure should be kept stable (fluctuation within ±0.5MPa), which can ensure the uniform diameter of the strip and the consistency of the masterbatch quality.

2.2.6 Cooling and Solidification

The extruded strip-shaped semi-finished products are sent to a cooling device for rapid cooling and solidification. The cooling method for masterbatch is usually water tank cooling, and the cooling water temperature is controlled at 20-30℃. The length of the cooling water tank is 3-5 mika, and the cooling time is 2-4 minuke. Rapid cooling can make the strip solidify quickly, maintain the shape and size of the strip, and avoid deformation and adhesion.

It should be noted that the cooling speed should be uniform. If the cooling speed is too fast, the internal stress of the strip will be too large, and the strip will be brittle and easy to break during granulation; if the cooling speed is too slow, the strip will be soft and easy to adhere, affecting the granulation effect. Ma hope o ka hoʻoluʻu, the surface of the strip should be dry, smooth and free of bubbles and cracks.

2.2.7 Cutting and Granulation

After cooling and solidification, the strip is sent to a granulator for cutting to form granular masterbatch products. The granulator is equipped with a rotary knife and a fixed knife, and the cutting speed is adjustable (generally 500-1000 rpm). The particle size of the masterbatch is controlled by adjusting the cutting speed and the speed of the strip conveying. The common particle size of masterbatch is 2-5mm (length and diameter are basically the same), which is convenient for mixing with plastic raw materials during later use.

The granulator should be equipped with a screening device to remove unqualified particles (such as too large, too small, agglomerated or broken particles). The qualified particles enter the next process, and the unqualified particles are crushed and recycled (after drying and premixing, they are re-extruded and granulated).

2.2.8 Ka nānā ʻana, Nānā a me ka Packaging

Hoʻouna ʻia ka masterbatch granulated i kahi pale vibrating no ka nānā ʻana no ka wehe hou ʻana i nā ʻāpana kūpono ʻole a me nā haumia.. Hoʻolako ʻia ka pale vibrating me kahi pale multi-layer (ʻokoʻa ka nui mesh), hiki ke pale i nā ʻāpana masterbatch o nā kikoʻī like ʻole e like me nā pono o ka mea kūʻai aku.

Ma hope o ka nānā ʻana, Pono ka masterbatch e nānā i ka maikaʻi. Loaʻa ka nui o nā mea nānā: kala kala (lokahi, kūlike me ka hāpana maʻamau), dispersibility (ʻike ʻia e ka microscope a i ʻole ke kala ʻāpana hoʻāʻo), hoʻopaʻa ʻana (hoao ikaika kala), ʻoluʻolu, puunaue ka nui o na mea liilii, etc. ʻO ka masterbatch wale nō i kūpono i nā kūlana maikaʻi hiki ke hoʻopili ʻia.

Hōʻailona ʻia ka ʻeke ʻeke me ka inoa huahana, kumu hoʻohālike, kala kala, hoʻopaʻa ʻana, ʻano lawe lawe, lā hana, ola mālama, mea hana a me nā ʻike ʻē aʻe. Pono e mālama ʻia ka masterbatch i hoʻopili ʻia i kahi maloʻo, hale kūʻai anuanu a me ka makani, pale aku i ka lā a me ka makū, a ʻo ka lōʻihi o ka mālama ʻana 6-12 mahina.

2.3 Nā mea nui e pili ana i ka hopena Extrusion Twin-Screw Masterbatch

Hoʻopili pololei ka hopena o ka twin-screw extrusion i ka maikaʻi o ka masterbatch (dispersibility, ikaika kala, kūpaʻa). Nui nā kumu e pili ana i ka hopena extrusion, ʻo ka nui me nā hiʻohiʻona maka, ratio ratio, hopena hoʻohuihui, nā palena extrusion a me ka hana ʻana o nā mea hana. ʻO ka hoʻopaʻa ʻana i kēia mau kumu koʻikoʻi a me ka hana ʻana i nā hoʻoponopono ʻepekema hiki ke hōʻoia i ka paʻa o ka hopena extrusion a me ka kūlike o ka maikaʻi o ka huahana..

2.3.1 Nā ʻano mea ʻala

ʻO ke ʻano, nui ʻāpana, moisture content and purity of raw materials have a great impact on the extrusion effect. For pigments, the particle size should be uniform and fine (20-40 makaʻu), and the agglomeration degree should be low; organic pigments have poor heat resistance, so the extrusion temperature should be strictly controlled; inorganic pigments have high hardness, so the extruder should have good wear resistance. For carriers, the melting point and processing temperature should be consistent with the target plastic raw materials, and the compatibility with pigments should be good. For additives, the type and dosage should be reasonable, and the compatibility with carriers and pigments should be good.

Kahi mea hou aʻe, the moisture content of raw materials must be strictly controlled below 0.1%; if the moisture content is too high, it will cause bubbles and agglomeration in the masterbatch. The purity of raw materials is also very important; impurities in raw materials will not only affect the product quality, akā e komo pū i ka wili a me ka pahu o ka extruder.

2.3.2 Formula Ratio

The formula ratio of masterbatch (the ratio of pigment, carrier and additive) is the key to determining the quality of the product. The pigment content should be determined according to the coloring requirements and the type of pigment: high-concentration masterbatch (pigment content 50%-80%) can reduce the addition amount and production cost, but requires better dispersibility; low-concentration masterbatch (pigment content 10%-30%) has better dispersibility, but the addition amount is large and the production cost is high.

The dosage of dispersants is generally 1%-5% of the pigment dosage; too little dispersant will lead to poor dispersibility of pigments, a ʻoi aku ka nui o ka dispersant e hoʻopilikia i nā waiwai mechanical o ka masterbatch a me nā huahana kala. ʻO ke ʻano o nā mea hoʻohui ʻē aʻe (mea hoʻohui, mea hoʻopaʻa wela, lubricants) ʻo ka laulā 0.5%-3%, pono e hoʻoponopono ʻia e like me ke ʻano o ka masterbatch a me nā koi hoʻoili. Pono e mālama pono i ka ratio formula, a aia ka hewa i loko o ±1%, e hōʻoia i ka kūlike o ka maikaʻi o ka huahana ma waena o nā pūʻulu.

2.3.3 Pānaʻi Premixing

ʻO Premixing ke kumu o ka hana extrusion. Hoʻopili pololei ka like ʻana o ka premixing i ka hui ʻana a me ka hoʻopuehu ʻana o nā puaʻa i ka wā extrusion. Inā ʻaʻole kūlike ka premixing, ʻaʻole hiki ke hoʻopili like ʻia nā puaʻa i ka ʻili o ka mea lawe, ka hopena i ka agglomeration kūloko o nā pigments, ka hui ʻole ʻana o nā mea i ka wā extrusion, a hoʻemi i ka hoʻopuehu ʻana o ka huahana.

E hōʻoia i ka hopena premixing, it is necessary to control the mixing speed (800-1200 rpm), manawa hui (5-10 minuke) and mixing temperature (40-60℃). No ka masterbatch me ka nui o ka pigment maʻiʻo, hiki ke hooloihiia ka manawa premixing, and the dispersant can be added first and mixed with the pigment, then mixed with the carrier and other additives. Kahi mea hou aʻe, the premixed mixture should be inspected; if there are obvious pigment agglomerates, it should be crushed and remixed.

2.3.4 Nā ʻāpana Extrusion

Extrusion parameters are the most important factors affecting the extrusion effect, ʻo ka nui me ka wikiwiki o ka wili, ka wela extrusion a me ke kaomi extrusion.

• Ka māmā holo: The screw speed of twin-screw extruders for masterbatch processing generally ranges from 200 i 800 rpm. ʻOi aku ka kiʻekiʻe o ka māmā wili, ʻoi aku ka nui o ka ikaika ʻāwili a me ka ikaika friction i loaʻa i nā mea, the better the mixing and dispersing effect of pigments, and the higher the production efficiency. Eia naʻe, inā kiʻekiʻe loa ka māmā holo, pōkole loa ka manawa noho o nā mea i loko o ka lua extrusion, resulting in incomplete melting of the carrier, insufficient mixing of materials, and uneven dispersibility; inā haʻahaʻa loa ka māmā holo, ʻaʻole i lawa ka ikaika ʻāwili a me ka ikaika friction, the pigment agglomerates cannot be fully broken, and the production efficiency is low.
• The screw speed should be adjusted according to the type of masterbatch: for masterbatch with high pigment content and easy agglomeration (such as black masterbatch, white masterbatch), a higher screw speed (500-800 rpm) is needed to ensure the uniform dispersion of pigments; for masterbatch with organic pigments (poor heat resistance), a moderate screw speed (300-500 rpm) is needed to avoid overheating and pigment decomposition.
• Ka Mahana Extrusion: The extrusion temperature is the key to ensuring the melting of the carrier and the stability of the pigment. The temperature of each section of the barrel and die head must be precisely controlled according to the type of masterbatch (ʻano lawe lawe, ʻano puaʻa). He haʻahaʻa ka mahana o ka ʻāpana hānai (kiʻekiʻe iki ma mua o ka mahana maloʻo o nā mea maka), ʻo ia ka mea nui e pale i nā mea mai ka caking a hōʻoia i ka hānai ʻana; the temperature of the melting section is medium, which is mainly to promote the melting and plasticization of the carrier; the temperature of the mixing section is higher, which is mainly to enhance the shear and mixing effect, and promote the uniform dispersion of pigments; 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 strip.
• The temperature control precision should reach ±1℃. ʻo kahi laʻana, when processing PP masterbatch with organic pigments, the temperature of each section is: feeding section 110-130℃, melting section 170-190℃, mixing section 180-200℃, homogenizing section 170-190℃, die head section 160-180℃. If the temperature is too high, the pigment will decompose and the carrier will degrade; if the temperature is too low, the carrier will not be fully melted, and the pigment cannot be uniformly dispersed.
• Paʻi Extrusion: The extrusion pressure of masterbatch twin-screw extrusion generally ranges from 5 to 12MPa. 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 materials, and the denser the strip. Eia naʻe, if the pressure is too high, it will increase the energy consumption and wear of the equipment, and even cause the die head to block; if the pressure is too low, the materials cannot be fully compressed and mixed, the strip is loose, and the dispersibility is poor.
• The extrusion pressure should be adjusted according to the type of masterbatch and the die head size: for masterbatch with high pigment content and poor fluidity, a higher extrusion pressure is needed; for masterbatch with good fluidity, a moderate extrusion pressure is sufficient. The extrusion pressure should be kept stable, and the fluctuation should be within ±0.5MPa, to ensure the uniform diameter of the strip and the consistency of the masterbatch quality.

2.3.5 Equipment Performance

The performance of the twin-screw extruder directly determines the extrusion effect. The key performance indicators of the extruder include mixing and dispersing capacity, ka hoʻomalu wela, ʻaʻahu kūʻē, conveying capacity and intelligent control capacity. ʻO Zhuoyue piha piha o nā extruders (HTS BASIC/PLUS/SUPER, ZTE, HTE) ua hoʻolālā kūikawā ʻia no ka hana masterbatch, with excellent performance in these aspects, which can effectively meet the processing needs of different types of masterbatch.

3. Zhuoyue’s Full Series Extruders: Professional Solutions for Masterbatch Processing

Zhuoyue has long been engaged in the research, development and production of high-performance twin-screw extruders, and has accumulated rich experience in the field of masterbatch processing. According to the processing characteristics of masterbatch (kiʻekiʻe o ka puaʻa, maʻalahi agglomeration o nā puaʻa, strict temperature control requirements, high wear resistance requirements) and the diverse needs of manufacturers (different production scales, nā ʻano masterbatch like ʻole, different application fields), Zhuoyue has launched a full series of extruders suitable for masterbatch processing, including HTS BASIC series, HTS PLUS series, HTS SUPER series, ZTE series and HTE series. Each series has its own performance characteristics and targeted adaptation scenarios, which can provide personalized and efficient processing solutions for masterbatch manufacturers of different scales.

3.1 Core Advantages of Zhuoyue’s Extruders for Masterbatch Processing

Whether it is the high-end HTS SUPER series or the cost-effective ZTE series, all Zhuoyue’s extruders have the following core advantages, which are specially optimized for masterbatch processing, ensuring high-quality, hana pono a paʻa:

3.1.1 Excellent Mixing and Dispersing Effect

The core requirement of masterbatch processing is the uniform dispersion of pigments. All Zhuoyue’s twin-screw extruders adopt an intermeshing co-rotating structure, with a reasonable screw pitch, ke alakaʻi a me ka hoʻolālā lākiō kaomi. The intermeshing and rotating of the twin screws can generate strong shear force and kneading force, which can fully break the agglomerates of pigments (even small agglomerates of 100μm above), and make the pigments uniformly dispersed in the carrier. The mixing uniformity of the extruders can reach more than 95%, which is much higher than that of ordinary twin-screw extruders (85%-90%).

Kahi mea hou aʻe, the screws of all series of extruders adopt a modular design, which can freely combine different types of screw elements (nā mea lawe, huikau mea, nā mea ʻāhi) e like me ke ʻano o ka masterbatch (such as color masterbatch, white masterbatch, black masterbatch) and pigment characteristics. ʻo kahi laʻana, when processing black masterbatch with carbon black (easy agglomeration), hiki ke hoʻonohonoho hou i nā mea hui a me nā mea shearing e hoʻonui i ka hopena hui a me ka hoʻopuehu; when processing color masterbatch with organic pigments (poor heat resistance), more conveying elements and fewer shearing elements can be configured to shorten the residence time and avoid pigment decomposition.

3.1.2 Precise Temperature Control, Avoiding Pigment Decomposition

Masterbatch processing has strict requirements on temperature control, and the temperature fluctuation must be controlled within ±1℃ to avoid pigment decomposition and carrier degradation. All Zhuoyue’s extruders adopt an advanced intelligent temperature control system, which is composed of high-precision temperature sensors, heating elements and cooling elements. Ua maheleia ka barela i 4-6 independent temperature control sections, and the temperature of each section can be precisely adjusted and controlled in real time.

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 automatically adjust the heating power or start the cooling system to return the temperature to the set range. Kahi mea hou aʻe, the barrel of the extruder adopts a double-layer jacket design, which can realize rapid heating and cooling, and improve the response speed of temperature control. The die head is also equipped with an independent temperature control device, which ensures the uniform temperature of the die head and the stable shaping of the strip.

3.1.3 High Wear Resistance, Long Service Life

ʻO nā puaʻa inorganic e like me ka titanium dioxide a me ke kalapona ʻeleʻele he paʻakikī kiʻekiʻe, which will cause serious wear to the screw and barrel of the extruder during processing. Zhuoyue’s extruders adopt high-quality wear-resistant materials and advanced manufacturing technology to ensure the wear resistance of the core components.

The screws and barrels of HTS PLUS series, HTS SUPER series and HTE series are made of imported wear-resistant alloy steel (such as 38CrMoAlA), a e hoʻopaʻa ʻia i ka bimetallic composite a i ʻole ka lāʻau lapaʻau laser. The surface hardness of the screws and barrels can reach ≥65 HRC (HTS PLUS series, HTE moʻo) and ≥70 HRC (HTS SUPER series), which has extremely strong wear resistance and corrosion resistance, and can effectively resist the wear caused by high-hardness pigments. The service life of the screws and barrels is 2-3 times that of ordinary extruders, reducing the frequency of component replacement and the maintenance cost of the equipment.

The screws and barrels of HTS BASIC series and ZTE series are made of high-quality wear-resistant alloy steel with nitriding treatment, and the surface hardness can reach ≥60 HRC, which can meet the processing needs of ordinary masterbatch (pigment content ≤50%) and has a reasonable cost performance.

Based on years of industry experience, Zhuoyue summarizes the common problems in masterbatch twin-screw extrusion processing, analyzes the causes in detail, and provides corresponding solutions, which can help manufacturers quickly solve production problems and improve production efficiency and product quality.

5.1 Common Problem 1: Poor Dispersibility of Masterbatch, Color Spots and Streaks in Products

This is the most common problem in masterbatch processing, which is mainly manifested in uneven coloring of the masterbatch, ʻike ʻia ka puaʻa agglomerates, and color spots and streaks in the colored plastic products. The main causes and solutions are as follows:

5.1.1 Main Causes:

• (1) Raw material problems: The pigment particle size is too large, the agglomeration degree is high, and the drying is insufficient; the compatibility between the pigment and the carrier is poor; the dispersant dosage is insufficient or the type is improper.
• (2) Premixing problems: The mixing speed is too low, the mixing time is too short, the mixing temperature is improper, resulting in uneven premixing of raw materials.
• (3) Extrusion parameter problems: The screw speed is too low, the shear force is insufficient, and the pigment agglomerates cannot be fully broken; the extrusion temperature is too low, the carrier is not fully melted, and the pigment cannot be uniformly dispersed.
• (4) Equipment problems: The screw mixing elements are insufficient or worn; the barrel and screw are worn, resulting in reduced shear force; the die head is blocked, affecting the uniform extrusion of materials.

5.1.2 Solutions:

• (1) Optimize raw materials: Select pigments with small particle size and low agglomeration degree, and dry them thoroughly (moisture content ≤0.1%); select carriers compatible with pigments; replace appropriate dispersants and increase the dosage appropriately (i loko 1%-5% of the pigment dosage).
• (2) Improve premixing effect: Increase the mixing speed to 800-1200 rpm, extend the mixing time to 5-10 minuke, and control the mixing temperature at 40-60℃; for high-concentration masterbatch, add dispersant first and mix with pigment, then mix with carrier and other additives.
• (3) Adjust extrusion parameters: Increase the screw speed appropriately (500-800 rpm for high-concentration masterbatch), improve the shear force; increase the extrusion temperature appropriately to ensure that the carrier is fully melted (adjust according to the carrier type).
• (4) Maintain equipment: Replace worn screw mixing elements, ka pahu a me ka wili; clean the die head regularly to avoid blockage; check the equipment regularly to ensure that the screw and barrel are properly matched.

5.2 Common Problem 2: Pigment Decomposition and Discoloration of Masterbatch

This problem is mainly manifested in the discoloration of the masterbatch (such as yellowing, darkening), the color is inconsistent with the standard sample, and even peculiar smell is generated. It is mostly caused by overheating of the material during extrusion processing, which is common in organic pigment masterbatch and engineering plastic masterbatch. The main causes and solutions are as follows:

5.2.1 Main Causes:

• (1) Extrusion temperature is too high: The temperature of the mixing section, homogenizing section or die head is too high, exceeding the heat resistance limit of the pigment or carrier.
• (2) The residence time of the material is too long: The screw speed is too low, the compression ratio is too large, resulting in the material staying in the extrusion cavity for too long (ma mua o 3 minuke), and thermal decomposition occurs.
• (3) Poor heat dissipation of the equipment: The cooling system of the barrel fails, resulting in local overheating of the barrel.

5.3 Common Problem 3: High Wear of Screw and Barrel, Short Service Life

This problem is common in the processing of white masterbatch, black masterbatch and filler masterbatch, which is mainly manifested in the rapid wear of the screw and barrel, reduced shear force and mixing capacity of the extruder, and increased maintenance cost. The main causes and solutions are as follows:

5.3.1 Main Causes:

• (1) Raw material problems: The pigment or filler has high hardness (e like me ka titanium dioxide, kalapona ʻeleʻele, calcium carbonate), and the particle size is too large, which causes severe wear to the screw and barrel.
• (2) Extrusion parameter problems: The screw speed is too high, the shear force is too large, and the friction between the material and the screw/barrel is increased; the extrusion pressure is too high, which increases the wear of the screw and barrel.
• (3) Equipment problems: The screw and barrel are made of materials with poor wear resistance, or the processing technology is improper; the screw and barrel are not properly matched, resulting in uneven stress and increased wear.

5.3.2 Solutions:

• (1) Optimize raw materials: Select pigments or fillers with small particle size (20-40 makaʻu) and low hardness; crush and sieve the raw materials to remove large particles; add appropriate lubricants (0.5%-2%) to reduce the friction between the material and the screw/barrel.
• (2) Adjust extrusion parameters: Reduce the screw speed and extrusion pressure appropriately, and control the shear force within a reasonable range; avoid long-term high-speed and high-pressure operation of the equipment.
• (3) Select high-wear-resistant equipment: Select extruders with high-wear-resistant screws and barrels, such as Zhuoyue’s HTS PLUS, HTS SUPER and HTE series, whose screws and barrels are made of imported wear-resistant alloy steel and undergo bimetallic composite or laser cladding treatment, which can greatly improve the service life; regularly check the wear of the screw and barrel, and replace them in time when the wear is serious.

5.5 Common Problem 5: Poor Processing Fluidity of Masterbatch, Difficult Extrusion, Equipment Blockage

This problem is mainly manifested in the difficulty of material conveying and extrusion, haʻahaʻa hana pono, unstable extrusion pressure, and even blockage of the die head and extrusion cavity, which affects the normal production. The main causes and solutions are as follows:

5.5.1 Main Causes:

• (1) Raw material problem: The carrier has poor fluidity, or the pigment content is too high (ma mua o 80%), resulting in poor fluidity of the mixture; the raw material has high moisture content, which causes the material to agglomerate and block the feeding port.
• (2) Premixing problem: The premixing is uneven, and the dispersant is not fully mixed, resulting in poor fluidity of the material.
• (3) Extrusion parameter problem: The extrusion temperature is too low, the carrier is not fully melted, and the fluidity is poor; the screw speed is too low, the conveying capacity is insufficient; the die head hole is too small, and the extrusion resistance is too large.
• (4) Equipment problem: The screw conveying elements are worn, the conveying capacity is reduced; the feeding device fails, resulting in uneven feeding.

5.5.2 Solutions:

• (1) Optimize raw materials: Select carriers with good fluidity; reduce the pigment content appropriately (control within 80%); dry the raw materials thoroughly to control the moisture content below 0.1%.
• (2) Improve premixing effect: Extend the premixing time, increase the mixing speed, ensure that the dispersant is fully mixed with the pigment and carrier, and improve the fluidity of the mixture.
• (3) Adjust extrusion parameters: Increase the extrusion temperature appropriately to ensure that the carrier is fully melted; increase the screw speed to improve the conveying capacity; replace the die head with larger die holes to reduce extrusion resistance.
• (4) Maintain equipment: Replace worn screw conveying elements; check the feeding device regularly, and repair or replace the faulty parts in time; clean the feeding port and extrusion cavity regularly to avoid material accumulation and blockage.
