Masterbatch ya ƙunshi abubuwa na asali guda uku: pigments ko rini, masu ɗaukar kaya da ƙari. The proportion and performance of each element directly determine the quality and use effect of masterbatch.

Pigments or dyes are the core components that give masterbatch coloring performance, lissafin kudi 10%-80% na masterbatch abun da ke ciki (the specific proportion depends on the type of pigment, coloring requirements and masterbatch concentration). Pigments are divided into organic pigments and inorganic pigments: organic pigments have bright colors, high tinting strength, kyakkyawan gaskiya, but poor heat resistance and weather resistance, mainly used in low-temperature processing plastics (kamar PE, PP) and products with high color requirements (such as textiles, packaging films); inorganic pigments da kyau zafi juriya, juriya na yanayi da kwanciyar hankali na sinadarai, amma low tinting ƙarfi da matalauta bayyana gaskiya, galibi ana amfani da su a cikin robobin sarrafa zafin jiki (kamar robobin injiniya) da kayayyakin waje (kamar kayan gini, sassa na waje na mota).

2. Fasahar sarrafa Core na Masterbatch: Fasahar Twin-Screw Extrusion Technology

Sarrafa Masterbatch ya ƙunshi hadawa, extrusion, sanyaya, granulation da sauran matakai, among which twin-screw extrusion technology is the core technology of masterbatch mixing and granulation. Compared with single-screw extrusion technology, twin-screw extrusion technology has the advantages of strong mixing and dispersing capacity, madaidaicin sarrafa zafin jiki, gajeren lokacin zama, high production efficiency and strong adaptability to raw materials, which can effectively solve the key problems of masterbatch processing (such as pigment agglomeration, uneven mixing, low production efficiency) and ensure the quality of masterbatch products.

Masterbatch mixing is one of the main applications of twin-screw extruders. The quality of masterbatch is directly determined by the performance of the twin-screw extruder and the rationality of the processing process. The key requirements of masterbatch processing for twin-screw extruders are: karfi hadawa da watsawa sakamako (don tabbatar da daidaitaccen rarraba pigments), madaidaicin sarrafa zafin jiki (don kauce wa rugujewar launi da lalata mai ɗauka), dacewar karfi karfi (don karya pigment agglomerates ba tare da lalata barbashi mai launi ba), babban samar da inganci (don saduwa da yawan samar da buƙatun) da juriya mai kyau (don daidaitawa da lalacewa na manyan taurin pigments kamar titanium dioxide da carbon baki).

2.1 Sarrafa Wahalhalu na Masterbatch da Bukatu don Kayayyakin Extrusion

Ko da yake fasahar extrusion tagwaye ta dace da sarrafa masterbatch, saboda musamman na masterbatch abun da ke ciki (high pigment abun ciki, sauki agglomeration na pigments) da bukatun sarrafawa (uniform watsawa, barga yi), har yanzu akwai matsaloli da yawa a cikin ainihin sarrafawa. Babban matsalolin sarrafawa da daidaitattun buƙatun don kayan aikin extrusion sune kamar haka:

2.1.1 Pigment Agglomeration and Poor Dispersibility

Pigments (especially inorganic pigments such as titanium dioxide and carbon black) have strong polarity and large specific surface area, which are easy to agglomerate into large particles during storage and mixing. If the agglomerates cannot be fully broken and dispersed during extrusion processing, the masterbatch will have poor dispersibility, and the colored plastic products will have color spots, color streaks and uneven coloring, which will seriously affect the product quality. This is the most common and key difficulty in masterbatch processing.

This requires the extrusion equipment to have strong mixing and dispersing capacity and appropriate shear force. The twin-screw extruder should adopt an intermeshing co-rotating structure, kuma dunƙule ya kamata a sanye take da isassun abubuwa masu haɗawa da abubuwa masu shear don samar da ƙarfi mai ƙarfi da ƙarfi yayin juyawa., wanda zai iya karya pigment agglomerates gabaɗaya kuma ya sanya pigments ɗin su watse daidai gwargwado a cikin mai ɗaukar hoto.. Bugu da kari, gudun dunƙule da extrusion matsa lamba ya kamata a daidaita su dace da daban-daban na pigments da masterbatch taro..

2.1.2 Rushewar Pigment da Ragewar Dillali da Zazzaɓi ya haifar

Yawancin pigments (musamman Organic pigments) suna da ƙarancin juriya na zafi, da mai ɗaukar kaya (kamar PE, PP) Hakanan yana da ƙayyadaddun ƙayyadaddun yanayin zafi. Idan zafin zafin extrusion ya yi yawa ko kuma lokacin zama na kayan a cikin extruder ya yi tsayi da yawa, pigment zai bazu (yana haifar da dushewar launi, canza launi), kuma mai ɗauka zai ƙasƙanta (resulting in reduced mechanical properties of the masterbatch). This is another key difficulty in masterbatch processing.

This requires the extrusion equipment to have precise temperature control capacity and short residence time. The barrel of the extruder should be divided into multiple temperature control sections, and the temperature of each section should be precisely controlled within the optimal range (usually 150-220℃ for ordinary masterbatch, 200-280℃ for engineering plastic masterbatch), with a temperature control precision of ±1℃. The screw structure should be optimized to shorten the residence time of the material in the extruder (yawanci 1-3 mintuna), avoiding long-term contact between the material and high temperature.

2.1.3 Wear of Screw and Barrel Caused by High-Hardness Pigments

Inorganic pigments such as titanium dioxide and carbon black have high hardness (Mohs hardness 5-7), which will cause serious wear to the screw and barrel of the extruder during extrusion processing. If the screw and barrel have poor wear resistance, they will be worn quickly, resulting in reduced shear force and mixing capacity of the extruder, affecting the dispersibility of the masterbatch and reducing the service life of the equipment.

This requires the screw and barrel of the extruder to be made of high-quality wear-resistant materials and processed by advanced manufacturing technology. Misali, the screw and barrel can be made of imported wear-resistant alloy steel, and undergo bimetallic composite treatment or laser cladding treatment, which can greatly improve the wear resistance and corrosion resistance of the screw and barrel, and adapt to the processing of masterbatch with high-hardness pigments.

2.1.4 Instability of Product Quality Between Batches

Masterbatch processing requires strict control of various parameters (such as formula ratio, lokacin hadawa, extrusion temperature, dunƙule gudun, gudun ciyarwa). If the parameters fluctuate, the quality of the masterbatch (such as concentration, dispersibility, tinting strength) will be unstable, resulting in color difference between batches of colored products, which will affect the reputation of the manufacturer.

This requires the extrusion equipment to have intelligent control capacity and stable performance. The extruder should be equipped with a PLC intelligent control system, which can realize precise control of feeding speed, dunƙule gudun, extrusion temperature and other parameters, and store multiple sets of formula parameters. When producing different batches of masterbatch, only the corresponding parameters need to be called, avoiding repeated debugging, ensuring the stability of product quality between batches.

2.1.5 High Requirements on Processing Fluidity

Masterbatch has high pigment content, which will reduce the processing fluidity of the material. If the processing fluidity is too poor, the material will be difficult to convey and extrude, resulting in low production efficiency, unstable extrusion pressure and even equipment blockage.

This requires the extrusion equipment to have strong conveying capacity and adjustable shear force. The twin-screw extruder should adopt a reasonable screw pitch, lead and compression ratio design, and the screw should be equipped with sufficient conveying elements to ensure the smooth conveying of materials. Bugu da kari, the extrusion temperature can be appropriately adjusted to improve the processing fluidity of the material, and lubricants can be added to reduce the friction between materials.

2.2 Working Principle and Process Flow of Masterbatch Twin-Screw Extrusion

The twin-screw extrusion process of masterbatch is a complex physical mixing process, which mainly includes raw material pretreatment, premixing, ciyarwa, narkewa, mixing and shearing, extrusion, sanyaya, granulation, screening and packaging. The core purpose is to uniformly disperse pigments, carriers and additives to form high-quality masterbatch granules. The specific working principle and process flow are as follows:

2.2.1 Raw Material Pretreatment

Raw material pretreatment is the foundation of masterbatch extrusion processing, which directly affects the mixing effect and product quality. The raw materials of masterbatch mainly include pigments/dyes, masu dako, additives (dispersants, masu jituwa, heat stabilizers, da dai sauransu.). The pretreatment steps are as follows:

• Drying Treatment: Some pigments (such as organic pigments) and carriers (kamar PA, PET) suna da yawan sha ruwa. If the moisture content is too high, it will cause bubbles, agglomeration and other defects in the masterbatch during extrusion processing, and even cause hydrolytic degradation of the carrier. Saboda haka, the raw materials must be dried before processing. The drying temperature and time are determined according to the type of raw material: misali, organic pigments are dried at 60-80℃ for 2-4 hours, PE/PP carriers are dried at 80-100℃ for 3-5 hours, and PA carriers are dried at 100-120℃ for 6-8 hours. 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 raga, which is conducive to the uniform mixing of raw materials and the breaking of pigment agglomerates during extrusion.
• Cire Najasa: The raw materials may contain impurities (such as metal particles, stones, kura) during production and transportation. Impurities not only affect the quality of the masterbatch, but also wear the screw and barrel of the extruder, and even cause equipment blockage. Saboda haka, the raw materials must be filtered and removed before use, using a filter screen with appropriate mesh size to remove impurities.

2.2.2 Premixing

Premixing is the key step to improve the mixing and dispersing effect of masterbatch. According to the formula ratio, the dried, crushed and impurity-removed pigments, carriers and additives are put into a high-speed mixer for premixing. The purpose of premixing is to make the pigments and additives uniformly adhere to the surface of the carrier particles, form a preliminary mixture, and lay a foundation for the uniform dispersion during extrusion.

The key parameters of premixing are mixing speed, mixing time and mixing temperature. The mixing speed is generally 800-1200 rpm, the mixing time is 5-10 mintuna, and the mixing temperature is controlled at 40-60℃. The appropriate mixing temperature can improve the adhesion of additives (kamar masu rarrabawa) to the carrier and pigments, promoting uniform mixing. For masterbatch with high pigment content (kamar 50% a sama), the premixing time can be appropriately extended, and a small amount of dispersant can be added first to improve the dispersibility of pigments. After premixing, the mixture should be uniform in color, without obvious pigment agglomerates and additive particles.

2.2.3 Ciyarwa da Bayarwa

The premixed mixture is sent to the feeding hopper of the twin-screw extruder through a screw feeder or a belt feeder. The feeding device of the extruder is usually equipped with a frequency conversion speed regulation function, which can adjust the feeding speed according to the screw speed and extrusion speed to ensure that the materials enter the extrusion cavity stably and uniformly, avoiding material accumulation or insufficient feeding.

The feeding hopper is also equipped with a drying device (such as an electric heating jacket) to prevent the raw materials from absorbing moisture again during feeding. For masterbatch with high pigment content and poor fluidity, a forced feeding device can be selected to ensure the smooth feeding of materials. Bugu da kari, the feeding port of the extruder should be smooth, without dead corners, to avoid material sticking and accumulation.

2.2.4 Narkewa, Mixing and Shearing

The materials entering the extrusion cavity of the twin-screw extruder are pushed forward continuously by the rotating screws. The extrusion cavity is composed of a screw and a barrel, kuma ƙarar rami na extrusion a hankali yana raguwa tare da jagorar axis. When the screws rotate, the materials are gradually compressed under the action of the screws and the barrel, kuma matsa lamba a cikin kogon extrusion yana ƙaruwa a hankali (generally 5-12MPa).

A lokaci guda, the materials are subjected to strong shear force and friction force generated by the relative movement between the screws and the barrel, da kuma tsakanin screw flights. The shear force and friction force can fully break the agglomerates of pigments, make the pigments uniformly dispersed in the melted carrier, and promote the fusion and compatibility between the pigment, carrier and additives. The friction force can also generate a certain amount of heat, which is combined with the external heating of the barrel (electric heating or steam heating) to make the carrier gradually melt and plasticize.

The barrel of the extruder is usually divided into 4-6 sassan kula da zafin jiki (sashen ciyarwa, sashin narkewa, hadawa sashe, homogenizing sashe, mutu head section), and the temperature of each section is precisely controlled according to the type of masterbatch (nau'in mai ɗaukar hoto, pigment type). Misali, when processing PE masterbatch, the temperature of the feeding section is 100-120℃, the melting section is 160-180℃, the mixing section is 170-190℃, the homogenizing section is 160-180℃, and the die head section is 150-170℃. The precise temperature control can ensure that the carrier is fully melted without thermal decomposition, and the pigments are not decomposed or discolored.

The screw of the twin-screw extruder adopts a modular design, which can freely combine different screw elements (such as conveying elements, abubuwan hadawa, shearing elements) according to the type of masterbatch. Misali, when processing masterbatch with high pigment content and easy agglomeration, more mixing elements and shearing elements can be configured to enhance the mixing and dispersing effect; when processing masterbatch with good fluidity, more conveying elements can be configured to improve production efficiency.

2.2.5 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 of the masterbatch extruder is usually equipped with multiple circular die holes (An ƙayyade lamba da girman ramukan mutu bisa ga girman barbashi na masterbatch). The material is extruded from the die head at a high speed to form continuous strip-shaped semi-finished products (the diameter of the strip is usually 2-5mm, which can be adjusted according to customer needs).

Yanayin zafin jikin mutun ya ɗan yi ƙasa kaɗan fiye da na sashin homogenizing, 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 mita, kuma lokacin sanyaya shine 2-4 mintuna. 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. Bayan sanyaya, 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 Nunawa, Inspection and Packaging

The granulated masterbatch is sent to a vibrating screen for screening to further remove unqualified particles and impurities. The vibrating screen is equipped with a multi-layer screen (different mesh sizes), which can screen out masterbatch particles of different specifications according to customer needs.

After screening, the masterbatch needs to undergo quality inspection. The inspection items mainly include: launi (daidaito, consistency with the standard sample), dispersibility (observed by microscope or test piece coloring), maida hankali (tinting strength test), abun ciki danshi, particle size distribution, da dai sauransu. Only the masterbatch that meets the quality standards can be packaged.

The packaging of masterbatch adopts sealed and moisture-proof packaging (such as plastic woven bags with inner plastic film, aluminum foil bags), and the packaging weight is usually 25kg/bag or 50kg/bag. The packaging bag is marked with the product name, abin koyi, launi, maida hankali, nau'in mai ɗaukar hoto, kwanan watan samarwa, shelf life, manufacturer and other information. The packaged masterbatch should be stored in a dry, sito mai sanyi da iska, avoiding direct sunlight and moisture, and the shelf life is generally 6-12 watanni.

2.3 Key Factors Affecting Masterbatch Twin-Screw Extrusion Effect

The effect of twin-screw extrusion directly affects the quality of masterbatch (dispersibility, tinting strength, stability). There are many factors affecting the extrusion effect, mainly including raw material characteristics, formula ratio, premixing effect, extrusion parameters and equipment performance. Mastering these key factors and making scientific adjustments can ensure the stability of the extrusion effect and the consistency of product quality.

2.3.1 Raw Material Characteristics

The type, girman barbashi, 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 raga), 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.

Bugu da kari, 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, but also wear the screw and barrel of the 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, and too much dispersant will affect the mechanical properties of the masterbatch and the colored products. The dosage of other additives (masu jituwa, heat stabilizers, man shafawa) is generally 0.5%-3%, which should be adjusted according to the type of masterbatch and processing requirements. The formula ratio should be strictly controlled, and the error should be within ±1%, to ensure the consistency of product quality between batches.

2.3.3 Premixing Effect

Premixing is the foundation of extrusion processing. The uniformity of premixing directly affects the mixing and dispersing effect of pigments during extrusion. If the premixing is uneven, the pigments cannot be uniformly adhered to the surface of the carrier, resulting in local agglomeration of pigments, uneven mixing of materials during extrusion, and reduced product dispersibility.

To ensure the premixing effect, it is necessary to control the mixing speed (800-1200 rpm), lokacin hadawa (5-10 mintuna) and mixing temperature (40-60℃). For masterbatch with high pigment content, the premixing time can be appropriately extended, and the dispersant can be added first and mixed with the pigment, then mixed with the carrier and other additives. Bugu da kari, the premixed mixture should be inspected; if there are obvious pigment agglomerates, it should be crushed and remixed.

2.3.4 Extrusion Parameters

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

• Gudun dunƙulewa: The screw speed of twin-screw extruders for masterbatch processing generally ranges from 200 ku 800 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 pigments, and the higher the production efficiency. Duk da haka, 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, insufficient mixing of materials, and uneven dispersibility; if the screw speed is too low, the shear force and friction force are insufficient, 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, farin 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.
• Extrusion Temperature: 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 (nau'in mai ɗaukar hoto, pigment type). The temperature of the feeding section is lower (slightly higher than the drying temperature of the raw materials), 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; 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℃. Misali, 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.
• Matsi na 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. Duk da haka, 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, madaidaicin sarrafa zafin jiki, sa juriya, conveying capacity and intelligent control capacity.

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 (high pigment abun ciki, sauki agglomeration na pigments, strict temperature control requirements, high wear resistance requirements) and the diverse needs of manufacturers (different production scales, different masterbatch types, 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, efficient and stable production:

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, 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 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%).

Bugu da kari, the screws of all series of extruders adopt a modular design, which can freely combine different types of screw elements (abubuwan isarwa, abubuwan hadawa, shearing elements) according to the type of masterbatch (such as color masterbatch, farin masterbatch, baki masterbatch) and pigment characteristics. Misali, when processing black masterbatch with carbon black (easy agglomeration), more mixing elements and shearing elements can be configured to enhance the mixing and dispersing effect; 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 Madaidaicin Kula da Zazzabi, 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. An raba ganga zuwa 4-6 independent temperature control sections, and the temperature of each section can be precisely adjusted and controlled in real time.

5. Common Problems and Solutions in Masterbatch Twin-Screw Extrusion Processing

In the actual production process of masterbatch, due to the influence of raw materials, formula, processing parameters and equipment performance, various problems often occur, which affect the quality of masterbatch and production efficiency. 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, obvious pigment 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 Magani:

• (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 (ciki 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 mintuna, 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, ganga da dunƙule; 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 (fiye da 3 mintuna), 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.
• (4) Raw material problems: The heat resistance of the pigment is poor, or the carrier is easy to degrade at high temperature.

5.2.2 Magani:

• (1) Adjust extrusion temperature: Reduce the temperature of the mixing section, homogenizing section and die head appropriately, and control it within the heat resistance range of the pigment and carrier (150-220℃ for ordinary masterbatch, 200-280℃ for engineering plastic masterbatch); check the temperature sensor regularly to ensure accurate temperature control.
• (2) Shorten the residence time: Increase the screw speed appropriately, reduce the compression ratio of the screw, and ensure that the residence time of the material in the extrusion cavity is 1-3 mintuna.
• (3) Maintain the cooling system: Check the cooling water circulation system regularly, clean the cooling pipe, and ensure that the barrel can dissipate heat normally; replace the faulty cooling element in time.
• (4) Optimize raw materials: Select pigments with good heat resistance (such as inorganic pigments for high-temperature processing); select carriers with stable performance and not easy to degrade; add appropriate heat stabilizers (0.5%-3%) to prevent pigment decomposition and carrier degradation.

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 (such as titanium dioxide, carbon black, 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 Magani:

• (1) Optimize raw materials: Select pigments or fillers with small particle size (20-40 raga) 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.

5.4 Common Problem 4: Instability of Product Quality Between Batches, Color Difference

This problem is mainly manifested in the inconsistency of masterbatch quality (such as concentration, dispersibility, launi) between different batches, resulting in color difference of downstream products, which affects the reputation of the manufacturer. The main causes and solutions are as follows:

5.4.1 Main Causes:

• (1) Formula problem: The formula ratio is not strictly controlled, and the dosage of pigment, dispersant and other additives fluctuates (error exceeds ±1%).
• (2) Raw material problem: The performance of raw materials (such as pigment tinting strength, carrier melting point) of different batches is inconsistent.
• (3) Processing parameter problem: The extrusion temperature, dunƙule gudun, feeding speed and other parameters fluctuate between different batches, resulting in inconsistent processing effect.
• (4) Equipment problem: The equipment has poor stability, and the parameters (such as temperature, matsa lamba) cannot be kept stable for a long time.

5.4.2 Magani:

• (1) Strictly control the formula ratio: Use high-precision weighing equipment to weigh raw materials, and the error is controlled within ±1%; establish a formula management system, and record the dosage of each raw material in detail.
• (2) Standardize raw material procurement and inspection: Select raw material suppliers with stable quality, and inspect the performance of raw materials (such as tinting strength, girman barbashi, abun ciki danshi) before use; for raw materials of different batches, conduct trial production first to ensure consistent performance.
• (3) Standardize processing parameters: Use an intelligent control system (such as Zhuoyue’s PLC control system) to store the processing parameters of different masterbatch, and call the corresponding parameters when producing different batches, avoiding repeated debugging; regularly check the equipment parameters to ensure stable operation.
• (4) Establish quality inspection system: Conduct strict quality inspection on each batch of masterbatch, ciki har da launi, dispersibility, concentration and other indicators, and only deliver the products that meet the standards.

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, low production efficiency, 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 (fiye da 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 Magani:

• (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.
