Most engineering plastics (ເຊັ່ນ PA, PBT, PPS) are sensitive to overheating and hydrolytic degradation. ຖ້າອຸນຫະພູມການປຸງແຕ່ງແມ່ນສູງເກີນໄປຫຼືເວລາທີ່ຢູ່ອາໄສໃນ extruder ຍາວເກີນໄປ, ລະບົບຕ່ອງໂສ້ໂມເລກຸນຂອງພາດສະຕິກວິສະວະກໍາຈະແຕກ, ສົ່ງຜົນໃຫ້ມີການທໍາລາຍຄວາມຮ້ອນ, ເຊິ່ງຈະຫຼຸດຜ່ອນຄຸນສົມບັດກົນຈັກ, ຄວາມຕ້ານທານຄວາມຮ້ອນແລະການປະຕິບັດອື່ນໆຂອງຜະລິດຕະພັນ, ແລະແມ້ກະທັ້ງເຮັດໃຫ້ເກີດການປ່ຽນສີ, carbonization ແລະຂໍ້ບົກພ່ອງອື່ນໆ. ນອກຈາກນັ້ນ, ບາງພາດສະຕິກວິສະວະກໍາ (ເຊັ່ນ PA) ມີການດູດຊຶມນ້ໍາສູງ, ແລະຄວາມຊຸ່ມຊື່ນໃນວັດສະດຸຈະເຮັດໃຫ້ເກີດການເຊື່ອມໂຊມຂອງ hydrolytic ໃນລະຫວ່າງຂະບວນການປຸງແຕ່ງທີ່ມີອຸນຫະພູມສູງ, ຜົນກະທົບຕໍ່ຄຸນນະພາບຂອງຜະລິດຕະພັນ.

ນີ້ເຮັດໃຫ້ສອງຄວາມຕ້ອງການທີ່ສໍາຄັນສໍາລັບອຸປະກອນ extrusion: ທໍາອິດ, ຄວາມອາດສາມາດຄວບຄຸມອຸນຫະພູມທີ່ຊັດເຈນ, ເຊິ່ງສາມາດຄວບຄຸມອຸນຫະພູມການປຸງແຕ່ງຢ່າງເຄັ່ງຄັດພາຍໃນຂອບເຂດທີ່ດີທີ່ສຸດຂອງພາດສະຕິກວິສະວະກໍາ, ຫຼີກລ້ຽງການ overheating ທ້ອງຖິ່ນ, ແລະຄວາມແມ່ນຍໍາຂອງການຄວບຄຸມອຸນຫະພູມຄວນຈະສາມາດບັນລຸ ± 1 ℃; ທີສອງ, ເວລາທີ່ຢູ່ອາໄສສັ້ນ, which can reduce the time that the material stays in the extruder barrel, avoid thermal decomposition and hydrolytic degradation. Twin-screw extruders have the advantages of short residence time (ປົກກະຕິແລ້ວ 1-5 ນາທີ) ແລະການຄວບຄຸມອຸນຫະພູມທີ່ຊັດເຈນ, which are more suitable for engineering plastics processing than single-screw extruders (ເວລາທີ່ຢູ່ອາໄສ 5-10 ນາທີ).

2.1.2 High Requirements on Mixing and Dispersing Effect

In engineering plastics processing, it is often necessary to add modifiers (such as glass fiber, ເສັ້ນໄຍກາກບອນ, ທາລກ, ຕ້ານໄຟ, ເຂົ້າກັນໄດ້) to improve the performance of the product (such as reinforcing, toughening, ທົນໄຟ). ຕົວຢ່າງ, adding glass fiber to PA can improve its strength and dimensional stability; adding flame retardants to PBT can improve its flame retardancy. The uniform mixing and dispersion of modifiers in the engineering plastic matrix is crucial to the performance of the final product. If the mixing and dispersing effect is poor, the modifiers will agglomerate, resulting in uneven performance of the product, and even reduce the mechanical properties of the product.

This requires the extrusion equipment to have strong shearing force and mixing capacity. Twin-screw extruders adopt intermeshing co-rotating or counter-rotating twin-screw structure, and the relative movement between the screws can generate strong shear force and kneading force, which can fully break the agglomerates of modifiers, make the modifiers uniformly dispersed in the engineering plastic matrix, and ensure the mixing and dispersing effect. ນອກຈາກນັ້ນ, the modular design of the twin-screw can freely combine different screw elements (ເຊັ່ນ: ອົງປະກອບການຖ່າຍທອດ, ອົງປະກອບປະສົມ, ອົງປະກອບການຕັດ) according to the type of engineering plastic and modifier, further improving the mixing and dispersing effect.

2.1.3 High Requirements on Wear Resistance of Equipment

In the processing of reinforced engineering plastics (such as glass fiber reinforced PA, carbon fiber reinforced PPS), the added glass fiber, carbon fiber and other modifiers have high hardness, which will cause serious wear to the screw and barrel of the extruder during the extrusion process. If the screw and barrel have poor wear resistance, they will be worn quickly, resulting in reduced shearing force and mixing capacity of the extruder, affecting the product quality 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. Our HTS series extruders adopt imported wear-resistant alloy steel for the screw and barrel, and undergo bimetallic composite treatment or laser cladding treatment, which greatly improves the wear resistance and corrosion resistance of the screw and barrel, and can adapt to the processing of reinforced engineering plastics with high hardness modifiers.

2.1.4 High Requirements on Processing Fluidity and Pressure Control

Some engineering plastics (such as PPS, PEEK) have high viscosity and poor processing fluidity, which require the extruder to have strong conveying capacity and pressure control capacity to ensure the smooth progress of extrusion. If the conveying capacity is insufficient or the pressure control is unstable, it will cause uneven extrusion speed, unstable product size, and even equipment blockage.

Twin-screw extruders have strong conveying capacity and stable pressure control capacity. The intermeshing of the twin screws can generate strong pumping force, which can effectively convey high-viscosity engineering plastic materials; ໃນເວລາດຽວກັນ, extruder ໄດ້ຖືກຕິດຕັ້ງດ້ວຍເຊັນເຊີຄວາມກົດດັນທີ່ມີຄວາມແມ່ນຍໍາສູງ, which can monitor the extrusion pressure in real time and adjust the screw speed and feeding speed automatically to ensure the stability of the extrusion pressure and the smooth progress of processing.

2.2 Working Principle and Process Flow of Engineering Plastics Twin-Screw Extrusion

The twin-screw extrusion process of engineering plastics is a complex physical and chemical process, ເຊິ່ງກ່ຽວຂ້ອງກັບການໂຕ້ຕອບຂອງປັດໃຈຫຼາຍຢ່າງເຊັ່ນ: ອຸນຫະພູມ, ຄວາມກົດດັນ, ແຮງຕັດແລະເວລາ. The core purpose is to melt and plasticize the engineering plastic raw materials and modifiers, mix them uniformly, and then extrude them into the required shape (such as particles, ທໍ່, ແຜ່ນ, ເສັ້ນໃຍ) through the die head. ຫຼັກການການເຮັດວຽກສະເພາະແລະການໄຫຼຂອງຂະບວນການແມ່ນດັ່ງຕໍ່ໄປນີ້:

2.2.1 ການຮັກສາວັດຖຸດິບ

Raw material pretreatment is the foundation of engineering plastics extrusion processing, which directly affects the processing effect and product quality. The raw materials of engineering plastics mainly include engineering plastic resin (ເຊັ່ນ PA, PC, POM), modifiers (such as glass fiber, ເສັ້ນໄຍກາກບອນ, ທາລກ, ຕ້ານໄຟ), ເຂົ້າກັນໄດ້, lubricants and other additives. The pretreatment steps are as follows:

  • Drying Treatment: Most engineering plastics (ເຊັ່ນ PA, PBT, PPS) ມີການດູດຊຶມນ້ໍາສູງ, and the moisture in the raw materials will cause hydrolytic degradation during high-temperature processing, resulting in product defects (such as bubbles, ຮອຍແຕກ, reduced mechanical properties). ເພາະສະນັ້ນ, the raw materials must be dried before processing. The drying temperature and time are determined according to the type of engineering plastic: ຕົວຢ່າງ, PA6 is dried at 80-100℃ for 4-6 ຊົ່ວໂມງ, PA66 is dried at 100-120℃ for 6-8 ຊົ່ວໂມງ, PBT is dried at 120-140℃ for 2-4 ຊົ່ວໂມງ, PPS is dried at 150-160℃ for 3-5 ຊົ່ວໂມງ. ຄວາມຊຸ່ມຊື່ນຂອງວັດຖຸດິບແຫ້ງຄວນໄດ້ຮັບການຄວບຄຸມຂ້າງລຸ່ມນີ້ 0.1%-0.2%.
  • Premixing Treatment: ອີງຕາມອັດຕາສ່ວນສູດ, the dried engineering plastic resin, modifiers and additives are put into a high-speed mixer for premixing. The purpose of premixing is to make the modifiers and additives uniformly adhere to the surface of the resin particles, improve the mixing effect during extrusion, and avoid local agglomeration of modifiers. ຄວາມໄວການປະສົມໂດຍທົ່ວໄປແມ່ນ 800-1200 rpm, ແລະເວລາປະສົມແມ່ນ 5-10 ນາທີ. For some modifiers with poor compatibility (such as glass fiber and PA), a compatibilizer should be added during premixing to improve the compatibility between the modifier and the resin.
  • ການຂັດແລະ Sieving: For engineering plastic resins with large particle size or modifiers with uneven particle size (such as glass fiber), crushing and sieving treatment should be carried out to ensure the uniformity of raw materials and avoid affecting the mixing and dispersing effect during extrusion. ຂະຫນາດຂອງອະນຸພາກຂອງວັດຖຸດິບ crushed ຄວນໄດ້ຮັບການຄວບຄຸມຢູ່ທີ່ 20-40 ຕາຫນ່າງ.

2.2.2 ການໃຫ້ອາຫານ ແລະການຂົນສົ່ງ

The premixed raw materials are sent to the feeding hopper of the twin-screw extruder through a screw feeder or a belt feeder. ອຸປະກອນການໃຫ້ອາຫານຂອງ extruder ປົກກະຕິແລ້ວແມ່ນອຸປະກອນທີ່ມີຫນ້າທີ່ຄວບຄຸມຄວາມໄວການແປງຄວາມຖີ່, 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 to prevent the raw materials from absorbing moisture again during feeding.

2.2.3 ການລະລາຍ, Mixing and Shearing

ວັດສະດຸທີ່ເຂົ້າໄປໃນຮູ extrusion ຂອງ extruder twin-screw ແມ່ນ pushed ໄປຂ້າງຫນ້າຢ່າງຕໍ່ເນື່ອງໂດຍ screws ພືດຫມູນວຽນ.. ຢູ່ຕາມໂກນ extrusion ແມ່ນປະກອບດ້ວຍ screw ແລະ barrel, ແລະປະລິມານຂອງຮູ extrusion ຄ່ອຍໆຫຼຸດລົງຕາມທິດທາງແກນ. ເມື່ອສະກູຫມຸນ, ອຸປະກອນການໄດ້ຖືກບີບອັດຄ່ອຍໆພາຍໃຕ້ການປະຕິບັດຂອງ screws ແລະ barrel ໄດ້, ແລະຄວາມກົດດັນໃນຮູ extrusion ຄ່ອຍໆເພີ່ມຂຶ້ນ (generally 5-15MPa).

ໃນເວລາດຽວກັນ, ວັດສະດຸແມ່ນຂຶ້ນກັບແຮງ shear ທີ່ເຂັ້ມແຂງແລະແຮງ friction ທີ່ສ້າງຂຶ້ນໂດຍການເຄື່ອນໄຫວທີ່ກ່ຽວຂ້ອງລະຫວ່າງ screws ແລະ barrel ໄດ້., ເຊັ່ນດຽວກັນກັບການບິນລະຫວ່າງສະກູ. The shear force and friction force can fully break the agglomerates of modifiers, make the modifiers uniformly dispersed in the melted engineering plastic resin, and promote the fusion and compatibility between the modifier and the resin. ຜົນບັງຄັບໃຊ້ friction ຍັງສາມາດສ້າງຈໍານວນທີ່ແນ່ນອນຂອງຄວາມຮ້ອນ, ເຊິ່ງລວມກັບຄວາມຮ້ອນພາຍນອກຂອງຖັງ (ການໃຫ້ຄວາມຮ້ອນໄຟຟ້າຫຼືຄວາມຮ້ອນອາຍ) to make the engineering plastic resin gradually melt and plasticize.

ຖັງຂອງ extruder ປົກກະຕິແລ້ວແບ່ງອອກເປັນ 4-6 ພາກສ່ວນຄວບຄຸມອຸນຫະພູມ (ພາກສ່ວນການໃຫ້ອາຫານ, ພາກສ່ວນການລະລາຍ, ສ່ວນປະສົມ, ພາກສ່ວນ homogenizing, ພາກສ່ວນຫົວຕາຍ), and the temperature of each section is precisely controlled according to the type of engineering plastic. ຕົວຢ່າງ, when processing PA66+GF30 (glass fiber reinforced PA66), the temperature of the feeding section is 120-140℃, the melting section is 250-260℃, the mixing section is 260-270℃, the homogenizing section is 250-260℃, and the die head section is 240-250℃. The precise temperature control can ensure that the resin is fully melted without thermal decomposition, and the modifiers are uniformly dispersed.

2.2.4 Extrusion and Shaping

ໄດ້ melted ຢ່າງເຕັມສ່ວນ, ອຸປະກອນການປະສົມແລະການກະແຈກກະຈາຍແມ່ນ pushed ກັບຫົວຕາຍຂອງ extruder ໂດຍ screws ໄດ້. The die head is designed according to the shape of the final product: for the production of engineering plastic compounds (ເມັດ), the die head is equipped with multiple circular die holes (the number and size of die holes are determined according to the particle size of the granules); for the production of pipes, ແຜ່ນ, ເສັ້ນໃຍ, the die head is designed into corresponding shapes (such as circular die for pipes, flat die for sheets).

The material is extruded from the die head at a high speed to form continuous semi-finished products (such as strips for granules, ທໍ່, ແຜ່ນ). ອຸນຫະພູມຂອງຫົວຕາຍແມ່ນຕ່ໍາກວ່າເລັກນ້ອຍຂອງພາກສ່ວນ homogenizing, which can prevent the material from decomposing due to excessive temperature and ensure the shaping effect of the semi-finished products. The extrusion speed is controlled according to the type of engineering plastic and the shape of the product, generally ranging from 0.5-5m/min.

2.2.5 Cooling and Solidification

The extruded semi-finished products are sent to a cooling device for rapid cooling and solidification. The cooling method is determined according to the shape of the product: for strips (granule production), water tank cooling is usually used, and the cooling water temperature is controlled at 20-30℃, ແລະເວລາເຢັນແມ່ນ 2-5 ນາທີ; for pipes and sheets, air cooling or water spray cooling is used, and the cooling speed should be controlled to avoid product deformation due to uneven cooling. Rapid cooling can make the semi-finished products solidify quickly, maintain the shape and size of the products, and improve the mechanical properties of the products.

2.2.6 Cutting and Post-Processing

After cooling and solidification, the semi-finished products are processed into the final product through cutting or other post-processing steps. For the production of engineering plastic compounds (ເມັດ), the cooled strips are sent to a granulator for cutting, and the granulator is equipped with a rotary knife, which can cut the strips into granular products with uniform size (ຂະຫນາດຂອງອະນຸພາກໂດຍທົ່ວໄປແມ່ນ 2-5mm, ເຊິ່ງສາມາດປັບໄດ້ຕາມຄວາມຕ້ອງການຂອງລູກຄ້າ). For the production of pipes and sheets, the cooled semi-finished products are cut into the required length through a cutting machine; for the production of fibers, the cooled filaments are drawn and wound to form fiber products.

ນອກຈາກນັ້ນ, the final product also needs to undergo post-processing steps such as screening, inspection and packaging. The screening step is to remove unqualified products (ເຊັ່ນ: ໃຫຍ່ເກີນໄປ, ອະນຸພາກຂະຫນາດນ້ອຍເກີນໄປຫຼື agglomerated); the inspection step is to detect the performance (such as mechanical strength, ຄວາມຕ້ານທານຄວາມຮ້ອນ, ຄວາມຖືກຕ້ອງຂອງມິຕິລະດັບ) of the product to ensure that it meets the customer’s requirements; the packaging step is to package the qualified product in a sealed and moisture-proof manner to prevent the product from absorbing moisture and affecting the quality.

2.3 Key Factors Affecting Engineering Plastics Twin-Screw Extrusion Effect

The effect of twin-screw extrusion directly affects the quality and performance of engineering plastic products. There are many factors affecting the extrusion effect, ຕົ້ນຕໍລວມທັງຄຸນລັກສະນະວັດຖຸດິບ, ອັດຕາສ່ວນສູດ, ຜົນ​ກະ​ທົບ premixing​, ຕົວກໍານົດການ extrusion ແລະໂຄງສ້າງຫົວຕາຍ. 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 ລັກສະນະວັດຖຸດິບ

ປະເພດ, ຂະໜາດອະນຸພາກ, moisture content and purity of raw materials have a great impact on the extrusion effect. ຕົວຢ່າງ, the particle size of engineering plastic resin and modifiers should be uniform; if the particle size is uneven, it will lead to uneven melting and mixing of materials. The moisture content of raw materials must be strictly controlled below 0.1%-0.2%; ຖ້າຄວາມຊຸ່ມຊື່ນສູງເກີນໄປ, it will cause hydrolytic degradation of the material and bubbles in the product. ຄວາມບໍລິສຸດຂອງວັດຖຸດິບຍັງມີຄວາມສໍາຄັນຫຼາຍ; impurities ໃນວັດຖຸດິບ (such as metals, ແກນ, ຂີ້ຝຸ່ນ) will not only affect the product quality, ແຕ່ຍັງໃສ່ screw ແລະ barrel ຂອງ extruder ໄດ້, ແລະແມ້ກະທັ້ງເຮັດໃຫ້ອຸປະກອນອຸດຕັນ.

2.3.2 ອັດຕາສ່ວນສູດ

The formula ratio of engineering plastic compounds (the ratio of resin, modifiers and additives) is the key to determining the performance of the product. The type and dosage of modifiers should be determined according to the performance requirements of the product. ຕົວຢ່າງ, ເພີ່ມ 20%-40% of glass fiber to PA can significantly improve its strength and dimensional stability, but excessive glass fiber will reduce the toughness and processing fluidity of the product. ປະເພດ ແລະປະລິມານຂອງສານເຕີມແຕ່ງຍັງຈໍາເປັນຕ້ອງຖືກຈັບຄູ່ກັນຢ່າງສົມເຫດສົມຜົນ: compatibilizers can improve the compatibility between modifiers and resin, and the dosage is generally 0.5%-2%; lubricants can reduce the friction between materials and equipment, ປັບປຸງການປຸງແຕ່ງ fluidity, and the dosage is generally 0.3%-1%; antioxidants can prevent the material from thermal oxidation degradation during processing, and the dosage is generally 0.1%-0.5%.

2.3.3 ເອັບເຟັກການປະສົມກ່ອນ

Premixing is the foundation of extrusion processing. The uniformity of premixing directly affects the mixing and dispersing effect of modifiers during extrusion. ຖ້າ premixing ບໍ່ສະເຫມີກັນ, the modifiers cannot be uniformly adhered to the surface of the resin, resulting in local agglomeration of modifiers, uneven mixing of materials during extrusion, and reduced product performance. ເພື່ອຮັບປະກັນຜົນກະທົບ premixing, ມັນເປັນສິ່ງຈໍາເປັນທີ່ຈະຄວບຄຸມຄວາມໄວການປະສົມ, ເວລາປະສົມແລະອຸນຫະພູມປະສົມ: the mixing speed is 800-1200 rpm, ເວລາປະສົມແມ່ນ 5-10 ນາທີ, ແລະອຸນຫະພູມປະສົມໄດ້ຖືກຄວບຄຸມຢູ່ທີ່ 40-60 ℃ (ອຸນຫະພູມທີ່ເຫມາະສົມສາມາດປັບປຸງການຍຶດຕິດຂອງສານເຕີມແຕ່ງແລະສົ່ງເສີມການປະສົມເປັນເອກະພາບ).

2.3.4 ຕົວກໍານົດການ Extrusion

Extrusion parameters are the most important factors affecting the extrusion effect, ສ່ວນໃຫຍ່ລວມທັງຄວາມໄວ screw, ອຸນຫະພູມ extrusion ແລະຄວາມກົດດັນ extrusion.

  • ຄວາມໄວ Screw: The screw speed of twin-screw extruders for engineering plastics generally ranges from 100 ກັບ 1000 rpm. Our HTS series extruders can reach a maximum speed of 1000 rpm. ຄວາມໄວຂອງ screw ສູງຂຶ້ນ, ຫຼາຍແຮງ shear ແລະແຮງ friction ທີ່ໄດ້ຮັບໂດຍວັດສະດຸ, the better the mixing and dispersing effect of modifiers, ແລະປະສິດທິພາບການຜະລິດສູງຂຶ້ນ. ແນວໃດກໍ່ຕາມ, ຖ້າຄວາມໄວຂອງ screw ແມ່ນສູງເກີນໄປ, ເວລາທີ່ຢູ່ອາໄສຂອງວັດສະດຸໃນຮູ extrusion ແມ່ນສັ້ນເກີນໄປ, resulting in incomplete melting of the resin, insufficient mixing of materials, and uneven product quality; ຖ້າຄວາມໄວຂອງສະກູຕໍ່າເກີນໄປ, ແຮງ shear ແລະແຮງ friction ບໍ່ພຽງພໍ, the modifiers cannot be fully dispersed, ແລະປະສິດທິພາບການຜະລິດແມ່ນຕໍ່າ. The screw speed should be adjusted according to the type of engineering plastic and the type of modifier: for high-viscosity engineering plastics (such as PPS, PEEK), a lower screw speed is needed to ensure sufficient melting and mixing; for reinforced engineering plastics (such as glass fiber reinforced PA), a higher screw speed is needed to ensure the uniform dispersion of glass fiber.
  • ອຸນຫະພູມ extrusion: The extrusion temperature is the key to ensuring the melting and plasticization of engineering plastics. The temperature of each section of the barrel and die head must be precisely controlled according to the type of engineering plastic. ອຸນຫະພູມຂອງພາກສ່ວນການໃຫ້ອາຫານແມ່ນຕ່ໍາ (slightly higher than the drying temperature of the raw materials), ເຊິ່ງສ່ວນໃຫຍ່ແມ່ນເພື່ອປ້ອງກັນບໍ່ໃຫ້ວັດສະດຸຈາກການອົບແລະຮັບປະກັນການໃຫ້ອາຫານກ້ຽງ; ອຸນຫະພູມຂອງສ່ວນ melting ແມ່ນຂະຫນາດກາງ, which is mainly to promote the melting and plasticization of the resin; ອຸນຫະພູມຂອງສ່ວນປະສົມແມ່ນສູງກວ່າ, ເຊິ່ງສ່ວນໃຫຍ່ແມ່ນເພື່ອເສີມຂະຫຍາຍຜົນກະທົບ shear ແລະປະສົມ, and promote the uniform dispersion of modifiers; ອຸນຫະພູມຂອງພາກສ່ວນ homogenizing ແມ່ນຕ່ໍາກວ່າສ່ວນປະສົມເລັກນ້ອຍ, ເຊິ່ງສ່ວນໃຫຍ່ແມ່ນເພື່ອຮັບປະກັນອຸນຫະພູມທີ່ເປັນເອກະພາບແລະຄວາມຫນືດຂອງວັດສະດຸ, ແລະຫຼີກເວັ້ນການທໍາລາຍຄວາມຮ້ອນ; ອຸນ​ຫະ​ພູມ​ຂອງ​ພາກ​ສ່ວນ​ຫົວ​ຕາຍ​ແມ່ນ​ຕ​່​ໍ​າ​ເລັກ​ນ້ອຍ​ກ​່​ວາ​ພາກ​ສ່ວນ homogenizing​, which is to ensure the shaping effect of the semi-finished products. The temperature control precision should reach ±1℃ to avoid local overheating and thermal decomposition of the material.
  • ຄວາມກົດດັນ extrusion: The extrusion pressure of engineering plastics twin-screw extrusion generally ranges from 5 to 15MPa. ຄວາມກົດດັນໃນຮູ extrusion ສ່ວນໃຫຍ່ແມ່ນຖືກກໍານົດໂດຍອັດຕາສ່ວນການບີບອັດຂອງ screw ໄດ້, ຂະຫນາດຂຸມຕາຍແລະຄວາມໄວຂອງ screw. ຄວາມກົດດັນ extrusion ສູງຂຶ້ນ, the better the mixing and dispersing effect of materials, and the denser the product. ແນວໃດກໍ່ຕາມ, ຖ້າຄວາມກົດດັນສູງເກີນໄປ, ມັນຈະເພີ່ມການບໍລິໂພກພະລັງງານແລະການສວມໃສ່ຂອງອຸປະກອນ, ແລະແມ້ກະທັ້ງເຮັດໃຫ້ຫົວຕາຍເພື່ອຕັນ; ຖ້າຄວາມກົດດັນຕໍ່າເກີນໄປ, ວັດສະດຸບໍ່ສາມາດຖືກບີບອັດແລະປະສົມຢ່າງເຕັມສ່ວນ, the product is loose, ແລະການປະຕິບັດແມ່ນບໍ່ຫມັ້ນຄົງ. The extrusion pressure should be adjusted according to the type of engineering plastic and the shape of the product: for high-viscosity materials and products with small die holes, a higher extrusion pressure is needed.

2.3.5 ໂຄງສ້າງຫົວຕາຍ

The die head structure mainly includes the shape, size and number of die holes, which directly affects the shaping effect and quality of the product. For the production of engineering plastic compounds (ເມັດ), the die head should be equipped with multiple uniform die holes, and the size of the die holes should be matched with the particle size of the product; for the production of pipes and sheets, the die head should be designed according to the shape and size of the product, and the flow channel of the die head should be smooth to avoid material accumulation and local overheating. The die head should also be equipped with a temperature control device to ensure the uniform temperature of the die head and the stable shaping of the product.

3. Our HTS Series Extruders: Professional Solutions for Engineering Plastics Processing

ພວກ​ເຮົາ​ໄດ້​ມີ​ສ່ວນ​ຮ່ວມ​ດົນ​ນານ​ໃນ​ການ​ຄົ້ນ​ຄວ້າ​, development and production of high-performance twin-screw extruders, and have accumulated rich experience in the field of engineering plastics processing. According to the processing characteristics of engineering plastics (sensitivity to overheating and hydrolytic degradation, high requirements on mixing and dispersing effect, viscosity ສູງ) and application needs, we have developed the HTS series twin-screw extruders specially for engineering plastics processing. Our HTS series extruders adopt high-torque gearboxes, with a specific torque of 14Nm/cm³ and a maximum speed of up to 1000rpm, which can obtain higher output, shorter residence time, better dispersibility and more precise temperature control, perfectly adapting to the processing needs of various engineering plastics.

3.1 Core Advantages of HTS Series Extruders for Engineering Plastics Processing

3.1.1 High Torque and High Speed, ປະສິດທິພາບການຜະລິດສູງ

Engineering plastics have high viscosity and poor processing fluidity, which require the extruder to have strong torque and conveying capacity. Our HTS series extruders adopt high-torque gearboxes independently developed and manufactured by us (ຊຸດ HTS PLUS ແລະຊຸດ HTS SUPER) or imported from leading European manufacturers (ຊຸດ HTS BASIC), with a specific torque of 14Nm/cm³, which is much higher than that of ordinary twin-screw extruders (general torque is 8-12Nm/cm³). The high torque design ensures that the extruder can stably convey high-viscosity engineering plastic materials, avoid material accumulation and equipment blockage, and improve the stability of the extrusion process.

ໃນເວລາດຽວກັນ, the HTS series extruders have a high speed design, with a maximum speed of up to 1000rpm. The high speed can generate strong shear force and mixing force, which can fully break the agglomerates of modifiers, make the modifiers uniformly dispersed in the resin matrix, and improve the mixing and dispersing effect. ນອກຈາກນັ້ນ, the high speed design also greatly improves the production efficiency: ເມື່ອທຽບກັບ extruders ທໍາມະດາ, the production efficiency of HTS series extruders can be increased by 30%-50%, which can meet the large-scale production needs of engineering plastics enterprises.

3.1.2 Short Residence Time, Effectively Avoiding Thermal Degradation

As engineering plastics are sensitive to overheating and hydrolytic degradation, the residence time of materials in the extruder is crucial. Our HTS series extruders adopt an optimized screw structure and barrel design, with a short residence time of only 1-3 ນາທີ, which is much shorter than that of ordinary twin-screw extruders (5-10 ນາທີ) and single-screw extruders (10-15 ນາທີ). The short residence time can effectively reduce the contact time between the material and high temperature, avoid thermal decomposition and hydrolytic degradation of the material, and ensure the mechanical properties and heat resistance of the product.

ນອກຈາກນັ້ນ, the screw of the HTS series extruders adopts a modular design, and different screw elements can be freely combined according to the type of engineering plastic, which can further adjust the residence time of the material, ensuring that different types of engineering plastics can obtain the optimal residence time during processing.

3.3 Selection Suggestions for Engineering Plastics Extruders

When selecting twin-screw extruders for engineering plastics processing, enterprises need to comprehensively consider their own production needs, product types, processing scale, budget and other factors to ensure that the selected equipment can meet the actual processing needs and bring maximum economic benefits. The following are some specific selection suggestions:

3.3.1 Determine the Extruder Series According to the Type of Engineering Plastics

Different types of engineering plastics have different processing requirements, which determine the selection of extruder series. For general engineering plastics (PA6, PA66, POM, PET, PBT) with low modification degree (filling amount ≤30%), the HTS BASIC series is sufficient to meet the processing needs. Its medium torque and flexible configuration can balance processing effect and cost, which is very suitable for small and medium-sized enterprises that just start to engage in engineering plastics processing or focus on general-purpose products. For high-modified engineering plastics (ຈໍານວນຕື່ມ 30%-50%, such as glass fiber reinforced PA, carbon fiber reinforced PBT) and special engineering plastics with moderate processing difficulty (such as PPS), the HTS PLUS series is the preferred choice. Its high torque of 14Nm/cm³ and excellent mixing and dispersing capacity can effectively solve the problem of uneven dispersion of high-content modifiers, and its wear-resistant screw and barrel can adapt to the wear of hard modifiers, ensuring stable production. For high-end special engineering plastics (PEEK, PI, PSU, PES) and high-performance modified engineering plastics (filling amount ≥50%, such as carbon fiber reinforced PEEK), the HTS SUPER series must be selected. Its ultra-high torque, maximum 1000rpm speed and fully optimized key structure can cope with the high viscosity, high temperature resistance and strict processing requirements of high-end materials, avoid thermal decomposition and material degradation, and ensure the high performance of the final product.

3.3.2 Determine the Screw Diameter and Production Capacity According to the Processing Scale

The screw diameter of the twin-screw extruder directly determines the production capacity, and enterprises need to select the appropriate screw diameter according to their own production scale and order demand. For small-scale production (100ກິໂລ/ຊມ – 500ກິໂລ/ຊມ), such as small-batch customization, product research and development or small orders, the HTS BASIC series with screw diameter of 30mm – 65mm is suitable; for medium-scale production (500ກິໂລ/ຊມ – 2000ກິໂລ/ຊມ), such as mass production of general modified engineering plastics, the HTS PLUS series with screw diameter of 65mm – 110mm can meet the demand; for large-scale production (1000ກິໂລ/ຊມ – 3000ກິໂລ/ຊມ), such as large-scale production of high-end special engineering plastics or large orders from downstream enterprises, the HTS SUPER series with screw diameter of 80mm – 130mm is the best choice. It should be noted that when selecting, enterprises should not blindly pursue large production capacity. They should also consider the fluctuation of order quantity. If the order quantity is unstable, they can choose equipment with adjustable speed and flexible production capacity (such as HTS BASIC series with frequency conversion speed regulation function) to avoid waste of equipment resources and energy.

3.3.3 Consider the Modification Demand and Mixing Effect

If the enterprise’s main products are modified engineering plastics, the mixing and dispersing effect of the extruder is the key factor to be considered. For products that need to add a variety of modifiers (ເຊັ່ນ: ສານຕ້ານໄຟ, ເຂົ້າກັນໄດ້, reinforcing agents) ໃນເວລາດຽວກັນ, it is necessary to select extruders with excellent mixing performance, such as HTS PLUS series and HTS SUPER series with modular mixing screw elements. These two series can freely combine conveying elements, mixing elements and shearing elements according to the type of modifier, adjust the mixing intensity and residence time, and ensure that various modifiers are uniformly dispersed in the resin matrix. ຕົວຢ່າງ, when processing flame-retardant modified PBT, more mixing elements can be configured to ensure the uniform dispersion of flame retardants, avoid local flame retardancy insufficiency; when processing glass fiber reinforced PA, more shearing elements can be configured to break the agglomeration of glass fiber and improve the bonding force between glass fiber and resin. ນອກຈາກນັ້ນ, if the enterprise has the demand of multi-variety and small-batch modification, it is recommended to select the extruder with quick replacement of screw elements (such as the modular screw design of HTS series), which can reduce the time of equipment adjustment and improve production efficiency.

3.3.4 Consider the Cost Budget and Comprehensive Benefits

Cost budget is an important factor for enterprises to select equipment, but it is not advisable to pursue low cost blindly.

Increase the screw speed appropriately (within the range suitable for the material) to shorten the residence time of the material. The HTS series extruders can reach a maximum speed of 1000rpm, which can effectively shorten the residence time to 1-3 ນາທີ; 3. Strengthen the drying treatment of raw materials, strictly control the moisture content below 0.1%-0.2%, and use the drying device matched with the HTS series extruders to prevent the raw materials from absorbing moisture again during feeding; 4. Check and clean the die head regularly to ensure the smooth flow channel, avoid material accumulation; 5. If the problem persists, adjust the screw element combination, increase the number of conveying elements, and reduce the number of mixing elements to speed up the material conveying and shorten the residence time.

5.2 ບັນຫາ 2: Uneven Dispersion of Modifiers

Symptoms: The final product has uneven texture, obvious agglomeration of modifiers (such as glass fiber, ເສັ້ນໄຍກາກບອນ), and the mechanical properties (ຄວາມເຂັ້ມແຂງ, ຄວາມທົນທານ, ການຕໍ່ຕ້ານການສວມໃສ່) are uneven, which cannot meet the use requirements. This problem is common in the processing of modified engineering plastics.

ສາເຫດ: 1. The premixing effect of raw materials is poor, and the modifiers are not uniformly adhered to the surface of the resin; 2. The screw speed is too low, resulting in insufficient shear force and kneading force, and the modifiers cannot be fully broken and dispersed; 3.
