• Masterbatch tae: The most common type of masterbatch, which uses organic or inorganic pigments of various colors (such as red, ō'ō, blue, matie, orange) as coloring components, and is used for coloring plastic products of various colors. The tinting strength, color brightness and dispersibility of color masterbatch are the key indicators to measure its quality.
• White Masterbatch: Using titanium dioxide (TiO2) as the main coloring component, it is used for whitening plastic products or as a base color for light-colored masterbatch. The whiteness, covering power and dispersibility of white masterbatch are the key indicators. Titanium dioxide has high hardness, which has high requirements on the wear resistance of extrusion equipment.

2. Core Processing Technology of Masterbatch: Te mau rave'a aravihi apî

Masterbatch processing mainly includes mixing, hutiraa, te toetoe, granulation and other processes, among which twin-screw extrusion technology is the core technology of masterbatch mixing and granulation. Ia faaauhia i te mau rave'a aravihi apî, twin-screw extrusion technology has the advantages of strong mixing and dispersing capacity, te faatereraa papu i te anuvera, short residence time, 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. E faataahia te huru o te masterbatch na roto i te rave'a a te rave'a haaparareraa e te ti'araa o te ohipa. Te mau titauraa rahi no te faanahoraa i te masterbatch no te mau matini roro uira: te hoê anoiraa puai e te haaparareraa (no te haapapu i te parareraa hoê â o te mau pigments), te faatereraa papu i te anuvera (no te ape i te parariraa o te pigment e te inoraa o te mau mea amo), te puai kutikuti (no te vavahi i te mau hu'ahu'a pigment ma te faaino ore i te mau hu'ahu'a pigment), te aravihi rahi no te hamaniraa (no te pahono i te mau hinaaro o te hamaniraa rahi) e te pato'iraa maitai i te ahu (no te faaafaro i te mau tao'a tahi etaeta mai te titanium dioxide e te carbon black).

2.1 Te mau fifi o te Masterbatch e te mau titauraa no te mau rave'a haaparareraa

Noa'tu e, ua tano te mau rave'a aravihi no te faatere i te mau rave'a aravihi, no te huru taa ê o te hamaniraa masterbatch (te mau pigment teitei, easy agglomeration of pigments) e te mau titauraa no te faaauraa (uniform dispersion, ha'utiraa papû), there are still many difficulties in actual processing. The main processing difficulties and corresponding requirements for extrusion equipment are as follows:

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.

E titau te reira i te mau ravea no te faaî i te mau ravea no te anoi e no te haaparare i te hoê puai kutikuti e tano. E mea ti'a i te mau hu'ahu'a e piti ia farii i te hoê hamaniraa hu'ahu'a, e e mea ti'a ia faaî i te hi'o i te mau hu'ahu'a ano'i e te mau hu'ahu'a kutikuti no te faatupu i te hoê puai kutikuti e te puai i te taime a hurihia'i, o te nehenehe e vavahi roa i te mau hu'ahu'a pigment e e haaparare i te mau pigment i roto i te mauhaa afai. I te horo'a i roto i, E tia ia tauihia te vitiviti o te hi'o e te faaheporaa ia au i te mau huru pigment e te mau faito masterbatch.

2.1.2 Te parariraa o te pigment e te inoraa o te carrier i faatupuhia e te veavea rahi

Te rahiraa o te mau pigment (te mau pigment iho â râ) aita to ratou e aravihi no te patoi i te veavea, e te taata amo (mai te PE, PP) E otia atoa to ' na no te patoi i te anuvera. If the extrusion temperature is too high or the residence time of the material in the extruder is too long, the pigment will decompose (resulting in color fading, te tauiraa), and the carrier will degrade (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℃. E tia ia faaapî i te hamaniraa o te hi'o no te haapoto i te taime no te faaearaa o te mau tao'a i roto i te extruder (ravehia 1-3 miniti), te aperaa i te farereiraa maoro i rotopu i te mau tao'a e te anuvera rahi.

2.1.3 Te mau pigments teitei tei faatupu i te mau hu'ahu'a e te mau hu'ahu'a

E mea etaeta roa te mau pigment ino mai te titanium dioxide e te carbone ereere (Te etaeta o Mohs 5-7), o te faatupu i te ino rahi i nia i te hi'o e te farii o te extruder i te taime a faaohipahia ' i te extruder. Mai te mea e, aita te hi'o e te farii e nehenehe e pato'i i te ahu, E oomo oioihia ratou, e faaiti te reira i te puai kutikuti e te aravihi no te anoi i te extruder, Te faaino nei te reira i te parareraa o te masterbatch e te faaitiraa mai i te oraraa o te mau ravea.

This requires the screw and barrel of the extruder to be made of high-quality wear-resistant materials and processed by advanced manufacturing technology. Moekara, 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, te taime no te anoiraa, extrusion temperature, te vitiviti, te vitiviti). If the parameters fluctuate, the quality of the masterbatch (such as concentration, te purara, 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, te vitiviti, extrusion temperature and other parameters, and store multiple sets of formula parameters. When producing different batches of masterbatch, ana'e te mau taahiraa e au i te reira e titauhia ia piihia, ma te ape i te mau hape tamau, 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, te hoê hoho'a no te arata'i e te faaheporaa, and the screw should be equipped with sufficient conveying elements to ensure the smooth conveying of materials. I te horo'a i roto i, 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, te faaineineraa, te faaamuraa, te re'are'a, te anoiraa e te kutikuti, hutiraa, te toetoe, Te mau hu'ahu'a, te hi'opo'araa e te tapo'iraa. The core purpose is to uniformly disperse pigments, carriers and additives to form high-quality masterbatch granules. Teie i muri nei te parau tumu taa ê no te ohipa e te tereraa o te ohipa:

2.2.1 Te rapaauraa i te mau tao'a mata

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, te mau amo, te mau tao'a (te mau mea haaparare, te mau rave'a, heat stabilizers, e tē vai atura.). The pretreatment steps are as follows:

• Drying Treatment: Some pigments (such as organic pigments) and carriers (mai te PA, RIMA'ERE) Te vai ra te hoê faito pape teitei. Mai te mea e, e mea rahi roa te haumi, it will cause bubbles, agglomeration and other defects in the masterbatch during extrusion processing, and even cause hydrolytic degradation of the carrier. Āre'a, the raw materials must be dried before processing. The drying temperature and time are determined according to the type of raw material: Moekara, organic pigments are dried at 60-80℃ for 2-4 hora, PE/PP carriers are dried at 80-100℃ for 3-5 hora, and PA carriers are dried at 100-120℃ for 6-8 hora. 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 mesh, which is conducive to the uniform mixing of raw materials and the breaking of pigment agglomerates during extrusion.
• Te iritiraa i te viivii: The raw materials may contain impurities (such as metal particles, stones, raveroa) during production and transportation. Impurities not only affect the quality of the masterbatch, tera râ, a oomo atoa i te hi'o e te farii o te extruder, e tae noa ' tu te mau ravea haafifiraa. Āre'a, the raw materials must be filtered and removed before use, using a filter screen with appropriate mesh size to remove impurities.

2.2.2 Te faaineineraa

Premixing is the key step to improve the mixing and dispersing effect of masterbatch. Ia au i te faito, 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, te taime e te anuvera. I te rahiraa o te taime, e mea vitiviti te anoiraa 800-1200 rpm, te taime no te anoiraa 5-10 miniti, e e faaterehia te anuvera i ni'a i te 40-60°C. The appropriate mixing temperature can improve the adhesion of additives (mai te mau mea haaparare) to the carrier and pigments, promoting uniform mixing. For masterbatch with high pigment content (Tā'ore'a 50% i ni'a), 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 Te faaamuraa e te faaiteraa

E tonohia te anoiraa i roto i te apoo tamaaraa o te mau hu'ahu'a e piti na roto i te hoê hu'ahu'a hi'o e aore râ, te hoê ati. I te rahiraa o te taime, te vai ra te hoê ravea no te faatere i te vitiviti o te tauiraa i roto i te ravea tamaaraa o te extruder, 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. I te horo'a i roto i, the feeding port of the extruder should be smooth, without dead corners, to avoid material sticking and accumulation.

2.2.4 Te re'araa, Mixing and Shearing

E turai tamau noa te mau hu'ahu'a i te mau tao'a e tomo atu i roto i te apoo o te mau hu'ahu'a. Te vai ra i roto i te apoo extrusion te hoê hi'o e te hoê farii, e te iti noa ' tura te rahi o te apoo extrusion i nia i te e'a. Ia huri ana'e te mau viti, E tata'ihia te mau tao'a i raro a'e i te ohipa a te mau viti e te farii, e te faaheporaa i roto i te apoo extrusion e maraa mǎrû noa (generally 5-12MPa).

I te hoê â taime, E faaruru te mau tao'a i te puai kutikuti e te puai o te mau hu'ahu'a tei tupu mai na roto i te tereraa i rotopu i te mau viti e te farii, e i rotopu atoa i te mau manureva. 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. E nehenehe atoa te puai o te friction e faatupu i te hoê faito veavea, o te amuihia ' tu i te faahanahanaraa i rapae i te farii (te faahanahana uira e aore râ, te faahanahanaraa) to make the carrier gradually melt and plasticize.

I te rahiraa o te taime, e amahamaha te farii o te extruder i roto i te 4-6 mau tuhaa no te faatere i te anuvera (tuhaa tamaaraa, tuhaa melting, tuhaa anoiraa, tuhaa homogenization, die head section), and the temperature of each section is precisely controlled according to the type of masterbatch (huru amo, pigment type). Moekara, 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 (mai te faaiteraa i te mau hu'ahu'a, Te mau hu'ahu'a, kutikuti i te mau hu'ahu'a) according to the type of masterbatch. Moekara, 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

Te re'are'a taatoa, 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 (the number and size of die holes are determined according to the particle size of the 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, e nehenehe e tauihia ia au i te mau hinaaro o te taata hoo).

E mea iti a'e te anuvera o te upoo o te pohe i te anuvera o te tuhaa 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 Te toetoeraa e te haapapûraa

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 metres, and the cooling time is 2-4 miniti. 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. I muri a'e i te toetoeraa, 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 (I te 'āmui 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 (mai te rahi roa, 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 Te hi'opo'araa, 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: Tae (uniformity, consistency with the standard sample), te purara (observed by microscope or test piece coloring), te faatumuraa (tinting strength test), te haumi, particle size distribution, e tē vai atura. 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, mā'ohii, Tae, te faatumuraa, huru amo, mahana hamaniraa, shelf life, manufacturer and other information. The packaged masterbatch should be stored in a dry, fare vairaa tauihaa to'eto'e e te hau, avoiding direct sunlight and moisture, and the shelf life is generally 6-12 ava'e.

2.3 Key Factors Affecting Masterbatch Twin-Screw Extrusion Effect

The effect of twin-screw extrusion directly affects the quality of masterbatch (te purara, tinting strength, stability). There are many factors affecting the extrusion effect, e tae noa'tu i te mau huru o te mau tao'a mata, faito formula, Te mau faahopearaa, 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 Te mau huru o te mau tao'a mata

Te huru, te rahi o te hu'ahu'a, 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 mesh), 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.

I te horo'a i roto i, the moisture content of raw materials must be strictly controlled below 0.1%; mai te mea e, e mea rahi roa te haumi, it will cause bubbles and agglomeration in the masterbatch. E mea faufaa rahi atoa te viivii ore o te mau tao'a mata; impurities in raw materials will not only affect the product quality, tera râ, a oomo atoa i te hi'o e te farii o te extruder.

2.3.2 Faanahoraa

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 (ihirangi pigment 50%-80%) can reduce the addition amount and production cost, but requires better dispersibility; low-concentration masterbatch (ihirangi pigment 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 (te mau rave'a, heat stabilizers, hinu hinu) 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 Te faahopearaa

Premixing is the foundation of extrusion processing. The uniformity of premixing directly affects the mixing and dispersing effect of pigments during extrusion. Mai te mea e, e ere te premixing i te mea tano, 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.

No te haapapu i te faahopearaa o te premixing, E mea titauhia ia haapao i te vitiviti o te anoiraa (800-1200 rpm), te taime no te anoiraa (5-10 miniti) and mixing temperature (40-60°C). 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. I te horo'a i roto i, the premixed mixture should be inspected; if there are obvious pigment agglomerates, it should be crushed and remixed.

2.3.4 Te mau taahiraa

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

• Te vitiviti: The screw speed of twin-screw extruders for masterbatch processing generally ranges from 200 a 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. Āre'a, if the screw speed is too high, the residence time of the materials in the extrusion cavity is too short, resulting in incomplete melting of the carrier, 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, 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.
• 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 (huru amo, 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℃. Moekara, 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.
• Te faaheporaa: 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. Āre'a, if the pressure is too high, E faarahi te reira i te faaohiparaa i te ito e te mauiui o te mau ravea, e tae noa ' tu te faatupu i te upoo o te pohe; mai te mea e, e mea iti roa te faaheporaa, Eita te mau tao'a e nehenehe e faaî roa e e anoihia, 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, te faatereraa i te anuvera, te pato'iraa, conveying capacity and intelligent control capacity.

Moekara, 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 Te faatereraa i te anuvera, 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. The barrel is divided into 4-6 independent temperature control sections, and the temperature of each section can be precisely adjusted and controlled in real time.

Ua horo'ahia te hoê hi'opo'araa e te hoê faaararaa i te taime mau i roto i te faanahoraa no te faatere i te anuvera: if the temperature of any section exceeds the set range, E horoa te faanahoraa i te hoê faaararaa i te taime, and automatically adjust the heating power or start the cooling system to return the temperature to the set range. I te horo'a i roto i, 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 Te patoiraa teitei, Te oraraa roa o te taviniraa

E mea etaeta roa te mau pigment ino mai te titanium dioxide e te carbone ereere, which will cause serious wear to the screw and barrel of the extruder during processing.

The surface hardness of the screws and barrels can reach ≥65 HRC (HTS PLUS, Te mau faanahoraa HTE) and ≥70 HRC (HTS SUPER series), e puai roa to ' na patoiraa i te ahu e te ino, 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.

3.1.4 Te aravihi rahi no te hamaniraa, Energy Saving and Environmental Protection

Zhuoyue’s extruders adopt a high-torque gearbox and an optimized screw structure, which have strong conveying capacity and high production efficiency. Compared with ordinary twin-screw extruders, the production efficiency of Zhuoyue’s extruders can be increased by 20%-50%. Moekara, the production capacity of HTS SUPER series extruders can reach 1000-3000kg/h, which is suitable for large-scale mass production; the production capacity of ZTE series extruders is 100-500kg/h, which is suitable for small and medium-sized batch production.
