2. Hangarau Matua o te Whakakii Masterbatch Production: Hangarau Granulation Extrusion

Ko te kounga o te whakakao tangohanga e whakatau tika ana i nga tohu mahi matua o te masterbatch whakakii, penei i te whakamararatanga, te rahi matūriki me te taupū rewa.

2.1 Nga Ahuatanga o te Whakakii Rawa Masterbatch Raw me nga Whakaritenga mo nga Taputapu Tangohanga

Ko nga rauemi mata o te masterbatch whakakii te nuinga e toru nga waahanga: whakakī parakore (penei CaCO3, talc, BaSO4), kaikawe polymer (penei i te PE, PP, PVC) me nga taapiri (penei i nga dispersants, kaiwhakariterite, whakahinuhinu, antioxidants, etc.). He rereke nga ahuatanga o enei rauemi mata, e whakatakoto ana i nga whakaritenga motuhake mo nga taputapu tangohanga:

Tuatahi, he nui te pakeke o nga whakakī parakore, he pai te hototahi ki nga kaikawe polymer, a he ngawari ki te whakahiato. Ko te nuinga o nga whakakii parakore (penei CaCO3, talc) he hydrophilic, ko nga kaikawe polymer he hydrophobic, e arahi ana ki te hototahi kino i waenga i nga whakakii me nga kaikawe. Mena karekau te ranu me te kutikuti, ka agglomerate nga whakakī, e kore e taea te marara rite i roto i te kawe, ka hua te kore o te kounga o te whakakī masterbatch. I tua atu, ko te tino pakeke o nga whakakii pararopi ka nui te kakahu ki te wiri me te oko o te extruder i te wa o te tangohanga., e hiahia ana ki te wiri me te oko o te extruder kia tino kaha te mau kakahu.

Tuarua, Ko te ranunga o te masterbatch whakakī he nui te pokey me te ngoikore o te wai. Ko te taapiri i te maha o nga whakakii pararopi ka tino whakanui ake i te viscosity o te ranunga, whakaitihia te rerenga tukatuka, me te hiahia kia kaha te kawe me te kaha kutikuti o te extruder kia pai ai te haere o te whakarewatanga, te whakaranu me te tangohanga.

Tuatoru, he kuiti te awhe pāmahana tukatuka. He rereke nga reera o nga kapia kawe rereke me te pumau o te waiariki. Hei tauira, ko te rewa o PE ko 100-130 ℃, ko te rewa o te PP ko 160-170 ℃, me te PVC he ngawari te pirau i te wera nui (i runga ake i te 160 ℃). No reira, Ko nga taputapu tangohanga me whai kaha ki te whakahaere i te pāmahana ki te whakarite kia tino rewa te ranunga kaore he waiariki., me te karo i te pirau o nga taapiri me te kino o te mahi hua.

I runga i nga ahuatanga o runga ake nei, e kore e pai nga extruders kotahi-screw mo te hanga nui-nui me te kounga teitei o te whakakii masterbatch.. Na te mea he whaiti te awhe kutikuti o te extruder kotahi-wiri, he ngoikore te kaha o te papu me te kore o te horoi whaiaro. I te wa e tukatuka ana i nga ranunga teitei-nui me te whakakii-nui, he ngawari ki te whakaemi rauemi, te aukati me te whakaranu koretake i roto i te oko extruder, ka hua mai te ngoikore o te mararatanga o te masterbatch whakakī, te rahi matūriki pāhiwihiwi me te kounga hua kore iu. I tua atu, te extruder kotahi-wiri he nui te paunga pūngao i te tukatuka rauemi tiketike-whakakī, a kua tino ngenge te tiu me te oko, ka piki ake te utu whakaputa me te utu tiaki taputapu o nga umanga.

Ko nga extruders mahanga, i tetahi atu ringa, he tino painga ki roto i te whakangao masterbatch whakakiia kua noho hei taputapu auraki mo te whakakii i te masterbatch extrusion granulation. He whanui ake te awhe kutikuti o nga kutikuti mahanga, whai hua ake te mahi papu me te horoi whaiaro, ka taea te whakaoti i nga raru o te hototahi ngoikore, ngawari te whakahiato me te ngoikore o te wai o te whakakii i nga rauemi mata. Ko te whakawhiti me te hurihuri o nga mahanga mahanga ka taea te whakaputa i te kaha kutikuti me te kaha o te pokepoke, ka taea te wawahi i nga agglomerates o nga whakakī parakore, kia marara rite nga whakakii i roto i te kawe polymer, me te whakarite i te mararatanga me te pumau o te hua. I tua atu, te extruder māhanga-wiri he pai mana pāmahana tika, te urutau kaha ki nga rauemi mata, a ka taea te urutau ki te tukatuka o nga momo rereke, rerekē te nui whakakī o masterbatch whakakī, me te kaha o te whakaputanga me te iti o te kohi hiko.

2.2 Tikanga Mahi o te Whakakī Masterbatch Extrusion Granulation

Ko te tukanga tangohanga o te masterbatch whakakī he tukanga tinana me te matū, e uru ana ki te taunekeneke o nga mea maha penei i te pāmahana, pehanga, te kaha kutikuti me te wa. The specific working principle and process flow are as follows:

Tuatahi, te maimoatanga o mua. The raw materials of filler masterbatch (whakakī parakore, kapia kawe, tāpiritanga) need to be pretreated to ensure the quality of the final product. The specific steps include: 1) Drying treatment: Inorganic fillers (penei CaCO3, talc) are usually hydrophilic and contain a certain amount of moisture. If the moisture content is too high, it will affect the mixing effect and dispersibility of the materials, and even cause bubbles in the extruded masterbatch. No reira, the fillers need to be dried in a dryer (such as a hot air dryer, a vacuum dryer) to reduce the moisture content to below 0.5%. 2) Crushing and sieving: The carrier resin (penei i te PE, PP) is crushed into small particles or powder with a particle size of 20-40 mata, which is conducive to uniform mixing with fillers and additives. Inorganic fillers are also sieved to remove impurities and large particles, ensuring the fineness and uniformity of fillers. 3) Whakaranu-mua: According to the formula ratio, the dried fillers, carrier resin particles and additives (dispersants, kaiwhakariterite, whakahinuhinu, etc.) are put into a high-speed mixer for premixing. The mixing speed is generally 800-1200 rpm, and the mixing time is 5-10 meneti. The purpose of premixing is to make the additives evenly adhere to the surface of fillers and carrier resin, improve the compatibility between fillers and carrier, and lay a foundation for subsequent extrusion mixing. The dispersant is a key additive in premixing, which can form a protective film on the surface of the filler, reduce the surface energy of the filler, prevent the filler from agglomerating, and improve the dispersibility of the filler in the carrier resin.

Tuarua, feeding and conveying. Ka tukuna te ranunga i mua i te whakaranu ki te hopper whangai o te extruder mahanga-screw na roto i te kai huriwiri, te kai whitiki ranei.. Ko te tere whangai kia rite, kia tau, e rite ana ki te tere wiri me te tere tangohanga o te extruder, kia mau tonu te uru o nga rawa ki roto i te kohanga extrusion me te karo i te whakaemi rauemi, te kore rawa ranei o te kai. Ko te taputapu kai o te extruder kei te nuinga o te waa ki te mahi whakatikatika tere tere, ka taea te whakatika i te tere kai kia rite ki te ahuatanga o te whakaputanga.

Tuatoru, rewa, te ranu me te kutikuti. Ko nga mea e uru ana ki roto i te kohao tangohanga o te mahanga-taapiri extruder ka panaia whakamua tonu e nga hurihanga hurihuri.. Ko te kohao tangohanga he mea tito he huri me te oko, ā, ka heke haere te rōrahi o te kōhao extrusion i te ahunga tuaka. When the screws rotate, the materials are gradually compressed under the action of the screws and the barrel, ā, ka piki haere te pēhanga i roto i te kōhao extrusion (generally 3-15MPa). I taua wa ano, the materials are subjected to strong shear force and friction force generated by the relative movement between the screws and the barrel, as well as between the screw flights.

The shear force and friction force can fully break the agglomerates of inorganic fillers, make the fillers uniformly dispersed in the melted carrier resin, and promote the fusion and compatibility between the fillers and the carrier. The friction force can also generate a certain amount of heat, which is combined with the external heating of the barrel (whakamahana hiko, whakamahana mamaoa ranei) ki te hanga i te kapia kawe kia rewa me te whakaraiti. Ko te oko o te extruder te nuinga o wehewehea ki 3-6 nga waahanga whakahaere pāmahana (wahanga whangai, wahanga rewa, wahanga ranu, wāhanga homogenizing, etc.), a ko te pāmahana o ia waahanga ka tika te whakahaere i runga i te momo kaikawe kawe me te whakakii. Hei tauira, i te wa e tukatuka ana i te masterbatch kaikawe kawe whakakii, ko te mahana o te wahanga whangai he 80-100 ℃, ko te wahanga whakarewa he 120-140 ℃, ko te waahanga whakaranu he 140-150 ℃, me te wahanga homogenizing ko 130-140 ℃; i te wa e tukatuka ana te PP kawe whakakī masterbatch, ko te mahana o ia waahanga ko te 20-30 ℃ teitei ake i to te kaikawe PE.

Tuawha, te tangohanga me te hanga. Ko te tino rewa, Ko nga mea whakauru me te marara ka panaia ki te upoko mate o te extruder e nga wiri. The die head is equipped with multiple die holes (the number and size of die holes are determined according to the particle size of the masterbatch), and the material is extruded from the die holes at a high speed to form continuous strips of uniform thickness. The temperature of the die head is slightly lower than that of the homogenizing section, which can prevent the material from decomposing due to excessive temperature and ensure the shaping effect of the strips.

Tuarima, cooling and cutting. The extruded strips are sent to a cooling device (such as a water tank, an air-cooled conveyor) for rapid cooling. The cooling temperature is generally 20-30℃, and the cooling time is 2-5 meneti. Rapid cooling can make the strips solidify quickly, maintain the shape and size of the strips, and avoid deformation. Whai muri i te whakamatao, the strips are sent to a granulator for cutting. The granulator is equipped with a rotary knife, which can cut the strips into granular filler masterbatch with uniform size (the particle size is generally 2-5mm, which can be adjusted according to customer needs). The speed of the rotary knife is matched with the conveying speed of the strips to ensure that the particle size of the masterbatch is uniform.

Sixth, screening and packaging. The cut granular filler masterbatch is sent to a vibrating screen for screening, which can remove unqualified particles (such as too large, too small or agglomerated particles) and ensure the uniformity of the product. The qualified masterbatch is then sent to an automatic packaging machine for packaging. The packaging specifications can be adjusted according to customer needs (such as 25kg/bag, 50kg/bag), and the packaging should be sealed and moisture-proof to prevent the masterbatch from absorbing moisture and affecting the quality. After packaging, the products are stored in a dry, cool and ventilated warehouse.

2.3 Key Factors Affecting Filler Masterbatch Extrusion Granulation Effect

The effect of extrusion granulation directly affects the quality of filler masterbatch. There are many factors affecting the granulation effect, mainly including raw material characteristics, formula ratio, premixing effect, extrusion parameters and die head structure. Mastering these key factors and making scientific adjustments can ensure the stability of the granulation effect and the consistency of product quality.

2.3.1 Raw Material Characteristics:

The type, particle size, moisture content and purity of raw materials have a great impact on the granulation effect. Hei tauira, the particle size of inorganic fillers directly affects the dispersibility and fineness of the masterbatch. The finer the particle size of the filler (generally 800-2000 mata), the better the dispersibility, but the higher the cost and the easier it is to agglomerate; the coarser the particle size, the lower the cost, but the dispersibility is poor, which will affect the appearance and performance of the masterbatch. The moisture content of raw materials (especially fillers) should be controlled below 0.5%; if the moisture content is too high, it will cause bubbles in the masterbatch, affect the density and mechanical properties of the product. The purity of raw materials is also very important; impurities in raw materials (such as stones, konganuku, puehu) will not only affect the quality of the masterbatch, but also wear the screw and barrel of the extruder, and even cause equipment blockage.

2.3.2 Formula Ratio:

The formula ratio of filler masterbatch (the ratio of filler, carrier resin and additives) is the key to determining the performance and cost of the product. The filling amount of the filler should be determined according to the performance requirements of the downstream product and the processing capacity of the equipment. Too high filling amount will lead to poor dispersibility, low toughness and poor processing fluidity of the masterbatch; too low filling amount will reduce the cost reduction effect. The type and dosage of additives also need to be reasonably matched. Hei tauira, the dispersant dosage is generally 1%-3% of the filler dosage; too little dispersant will lead to poor dispersibility of the filler, and too much dispersant will affect the compatibility between the masterbatch and the downstream plastic products, and reduce the mechanical properties of the products. The compatibilizer is used to improve the compatibility between the filler and the carrier resin; the dosage is generally 0.5%-2%, which can significantly improve the dispersibility and mechanical properties of the masterbatch. The lubricant is used to reduce the friction between the materials and the screw, barrel and die head, improve the processing fluidity, and prevent the materials from sticking to the equipment; the dosage is generally 0.3%-1%.

2.3.3 Premixing Effect:

Premixing is the foundation of extrusion granulation. The uniformity of premixing directly affects the dispersibility of the filler in the carrier resin. If the premixing is uneven, the additives cannot be uniformly adhered to the surface of the filler and carrier, resulting in local agglomeration of the filler, uneven mixing of the materials during extrusion, and poor quality of the masterbatch. To ensure the premixing effect, it is necessary to control the mixing speed, mixing time and mixing temperature. The mixing speed is generally 800-1200 rpm, the mixing time is 5-10 meneti, and the mixing temperature is controlled at 40-60℃ (appropriate temperature can improve the adhesion of additives and promote uniform mixing).

2.3.4 Extrusion Parameters:

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

• Tere Tiu: The screw speed generally ranges from 150 ki 600 rpm. The higher the screw speed, the greater the shear force and friction force received by the materials, the better the mixing and dispersing effect of the filler, and the higher the production efficiency. Heoi ano, if the screw speed is too high, the residence time of the materials in the extrusion cavity is too short, resulting in incomplete melting of the carrier resin, insufficient mixing of the materials, and uneven particle size of the masterbatch; if the screw speed is too low, the shear force and friction force are insufficient, the filler cannot be fully dispersed, and the production efficiency is low. The screw speed should be adjusted according to the filling amount and type of filler masterbatch—for high-filling masterbatch, a higher screw speed is needed to ensure sufficient shearing and mixing.
• Extrusion Temperature: The extrusion temperature is divided into multiple sections (wahanga whangai, wahanga rewa, wahanga ranu, wāhanga homogenizing, die head section), and the temperature of each section needs to be precisely controlled according to the type of carrier resin and filler. The temperature of the feeding section is lower (slightly higher than the melting point of the carrier resin), which is mainly to prevent the materials from caking and ensure smooth feeding; the temperature of the melting section is medium, which is mainly to promote the melting and plasticization of the carrier resin; the temperature of the mixing section is higher, which is mainly to enhance the shear and mixing effect, and promote the uniform dispersion of the filler; the temperature of the homogenizing section is slightly lower than the mixing section, which is mainly to ensure the uniform temperature and viscosity of the materials, and avoid thermal decomposition; the temperature of the die head section is slightly lower than the homogenizing section, which is to ensure the shaping effect of the strips.
• Pehenga Tangohanga: The extrusion pressure is generally 3-15MPa. The pressure in the extrusion cavity is mainly determined by the compression ratio of the screw, the die hole size and the screw speed. The higher the extrusion pressure, the better the mixing and dispersing effect of the materials, and the denser the masterbatch particles. Heoi ano, 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 masterbatch particles are loose, and the performance is unstable.

2.3.5 Die Head Structure:

The die head structure mainly includes the number, shape and size of die holes. The shape of the die hole determines the cross-sectional shape of the extruded strips (such as circular, square), and the size of the die hole determines the initial diameter of the strips and the final particle size of the masterbatch. The smaller the die hole size, the greater the extrusion pressure, the better the mixing and dispersing effect, but the production capacity will be reduced; the larger the die hole size, the lower the extrusion pressure, the lower the production efficiency, but the particle size of the masterbatch is larger. The number of die holes affects the production capacity; the more the number of die holes, the higher the production capacity, but it is necessary to ensure that the pressure distribution is uniform, so as to avoid uneven thickness of the strips and uneven particle size of the masterbatch.

Adding 1%-4% of light calcium carbonate filler masterbatch can reduce the cost of the film, improve its toughness and anti-aging properties, and extend the service life of the film; barium sulfate filler masterbatch can improve the transparency and light transmittance of the film, which is conducive to the photosynthesis of crops.
• Irrigation Pipes and Fertilizer Bags: Irrigation pipes need to have good pressure resistance and wear resistance; fertilizer bags need to have good toughness and wear resistance. The filler masterbatch used is mainly heavy calcium carbonate filler masterbatch or talc filler masterbatch. Adding 5%-10% of heavy calcium carbonate filler masterbatch can improve the pressure resistance and wear resistance of irrigation pipes, whakaitihia te utu; te taapiri 3%-6% of talc filler masterbatch can improve the toughness and wear resistance of fertilizer bags, making them not easy to break during transportation and use.

4.2 Usage Methods of Filler Masterbatch

The correct use of filler masterbatch is crucial to ensure the quality of plastic products and give full play to the performance of the masterbatch. The usage methods of filler masterbatch mainly include mixing ratio, mixing method, processing parameter adjustment and precautions. The specific operation points are as follows:

4.2.1 Te Whakataunga o te Raraunga Whakaranu:

Ko te ōwehenga whakaranu o te masterbatch whakakī me te kirihou turanga (kapia kawe o nga hua kirihou) Ko te nuinga ka whakatauhia e te nui o te whakakii o te masterbatch, nga whakaritenga mahi o te hua whakamutunga me te kaha tukatuka o nga taputapu. Ko te whānuitanga ōwehenga whakaranu whānui 1%-20%, a ka taea te whakarite i te ōwehenga motuhake kia rite ki nga kaupapa e whai ake nei:

• Mo nga hua kirihou me nga whakaritenga mahi iti me nga whakaritenga whakahaere utu nui (penei i nga putea kirihou noa, garbage bags), te ōwehenga whakaranu ka taea 5%-20% (te whakamahi iti-ki-waenganui whakakī konupūmā pākawa waro whakakī masterbatch);
• Mo nga hua kirihou me nga whakaritenga mahi reo (penei i nga kiriata kirihou, nga wahanga werohanga noa), te ōwehenga whakaranu ka taea 2%-8% (te whakamahi i te reo whakakī konupūmā pākawa waro, talc, barium sulfate filler masterbatch ranei);
• Mo nga hua kirihou me nga whakaritenga mahi nui (penei i nga waahanga motuka, electronic product shells, high-grade films), te ōwehenga whakaranu ka taea 1%-5% (using high-filling, high-performance talc, barium sulfate or glass fiber reinforced filler masterbatch);
• For transparent or semi-transparent plastic products (such as plastic bottles, transparent films), the mixing ratio should be controlled at 1%-3%, and barium sulfate or light calcium carbonate filler masterbatch with fine particle size (runga 1250 mata) should be selected to avoid affecting the transparency of the products.

4.2.2 Mixing Method:

The mixing of filler masterbatch and base plastic should ensure uniformity, so as to avoid local agglomeration of the masterbatch and affect the performance of the final product. The common mixing methods include dry mixing and wet mixing, among which dry mixing is the most widely used in industrial production.

• Dry Mixing: This method is suitable for most filler masterbatch and base plastic (penei i te PE, PP, PVC). The specific steps are: tuatahi, dry the base plastic particles and filler masterbatch to remove moisture (the moisture content should be controlled below 0.5%); then, put the base plastic particles and filler masterbatch into a high-speed mixer according to the determined mixing ratio, and add an appropriate amount of lubricant (mehemea e tika ana) to mix uniformly. The mixing speed is generally 500-800 rpm, and the mixing time is 3-5 meneti. I muri i te ranu, the mixture can be directly sent to the extruder or injection molding machine for processing. The advantages of dry mixing are simple operation, kakama teitei, low cost and no pollution to the product.
• Wet Mixing: This method is suitable for filler masterbatch with poor dispersibility or base plastic with high viscosity (such as PVC paste). The specific steps are: mix the filler masterbatch with an appropriate amount of solvent (such as plasticizer, solvent oil) to form a paste, then add the paste to the base plastic and stir uniformly, and finally remove the solvent through heating or drying. The advantages of wet mixing are good mixing effect and uniform dispersion of the masterbatch; the disadvantages are complex operation, high cost, and easy residual solvent affecting the product quality. No reira, wet mixing is only used in special cases.

4.2.3 Adjustment of Processing Parameters:

When adding filler masterbatch to plastic processing, the processing parameters (such as temperature, pehanga, tere tīwiri) need to be properly adjusted according to the type and filling amount of the masterbatch to ensure the smooth progress of processing and the quality of the final product.

• Temperature Adjustment: The addition of filler masterbatch will increase the viscosity of the mixture, so the processing temperature needs to be appropriately increased by 5-15℃ compared with the processing temperature of pure base plastic. Hei tauira, when processing PE plastic with calcium carbonate filler masterbatch, the processing temperature can be increased by 5-10℃; when processing PP plastic with talc filler masterbatch, the processing temperature can be increased by 10-15℃. It should be noted that the temperature should not be too high to avoid thermal decomposition of the base plastic and additives.
• Pressure Adjustment: The addition of filler masterbatch will increase the resistance during processing, so the processing pressure (pehanga tangohanga, injection pressure) needs to be appropriately increased by 10%-20%. Hei tauira, when extruding plastic pipes with filler masterbatch, the extrusion pressure can be increased by 10%-15% to ensure the compactness and dimensional accuracy of the pipes; when injecting plastic parts with filler masterbatch, the injection pressure can be increased by 15%-20% to avoid defects such as insufficient filling and shrinkage.
• Screw Speed Adjustment: The screw speed should be adjusted according to the type and filling amount of the masterbatch. For high-filling masterbatch or masterbatch with poor dispersibility, the screw speed can be appropriately increased by 10%-15% to enhance the shear force and mixing effect, ensuring the uniform dispersion of the filler; for low-filling masterbatch or masterbatch with good dispersibility, the screw speed can be kept unchanged or slightly reduced to reduce energy consumption and wear of equipment.

4.2.4 Precautions for Use:

In the process of using filler masterbatch, the following precautions should be paid attention to to avoid affecting the processing effect and product quality:

• Moisture Prevention: Te whakakī matua (especially calcium carbonate, talc masterbatch) is easy to absorb moisture, which will cause bubbles, pinholes and other defects in the final product. No reira, the masterbatch should be stored in a dry, cool and ventilated warehouse, and should be dried before use (the drying temperature is 80-100℃, and the drying time is 2-4 haora).
• Hototahi: The carrier resin of the filler masterbatch should be consistent with or compatible with the base plastic of the product. Hei tauira, PE filler masterbatch should be used with PE base plastic, and PP filler masterbatch should be used with PP base plastic. If the carrier resin is incompatible with the base plastic, it will affect the compatibility between the masterbatch and the base plastic, resulting in poor dispersibility and reduced product performance.
• Uniform Mixing: The filler masterbatch and base plastic must be mixed uniformly. If the mixing is uneven, local agglomeration of the masterbatch will occur, ka puta he koha penei i te toka ma, black spots and agglomeration in the product, affecting the appearance and performance of the product.
• Dosage Control: The dosage of filler masterbatch should not exceed the maximum filling amount applicable to the equipment and product performance. Excessive dosage will lead to poor dispersibility, low toughness, poor processing fluidity and other problems of the product; insufficient dosage will not achieve the effect of cost reduction and performance improvement.
• Storage Period: The filler masterbatch has a certain storage period (generally 6-12 marama). If the storage period is exceeded, the masterbatch may absorb moisture, agglomerate or the performance of additives may degrade, affecting the use effect. No reira, the masterbatch should be used within the storage period.
