1. Overview of Engineering Plastics Industry and Core Performance Characteristics
1.1 Current Situation and Development Trend of Engineering Plastics Industry
Engineering plastics refer to a class of plastic materials that can be used as structural materials and bear mechanical loads in a wide temperature range. Compared with general plastics (such as polyethylene PE, polypropylene PP, polyvinyl chloride PVC), engineering plastics have more excellent comprehensive performance, and can meet the harsh use requirements in industrial production and high-end product manufacturing. በቅርብ ዓመታት ውስጥ, driven by the upgrading of downstream industries such as automotive lightweight, electrical and electronic intelligence, and medical device high-endization, the global engineering plastics market has shown a steady and rapid growth trend.
According to relevant industry data, the global engineering plastics market size has exceeded 100 ቢሊዮን ዶላር, and it is expected to maintain a compound annual growth rate of 7%-10% in the next five years. ከነሱ መካከል, Asia-Pacific is the world’s largest engineering plastics production and consumption market, accounting for more than 55% of the global market share, mainly due to the rapid development of automotive, electrical and electronic industries in China, India and other countries, as well as the continuous improvement of industrial supporting capacity and technological innovation level. ቻይና, as the world’s largest engineering plastics consumer and producer, has a huge market demand, and the annual output and consumption are growing at a double-digit rate, especially in the fields of new energy vehicles, 5G communications, and medical devices, the demand for high-performance engineering plastics is showing an explosive growth trend.
The development trend of the engineering plastics industry is mainly reflected in five aspects: አንደኛ, high performance and functionalization. With the continuous improvement of use requirements in downstream fields, engineering plastics are developing towards higher heat resistance, higher strength, better wear resistance and special functions (such as flame retardancy, አንቲስታቲክ, antibacterial, radiation resistance), to adapt to the harsh working environment of high temperature, high pressure, corrosion and radiation; ሁለተኛ, lightweight and integration.

Engineering plastics are sensitive to overheating and hydrolytic degradation, and have high requirements on processing temperature, shear force, residence time and temperature control precision. Our HTS series extruders are specially designed for the processing characteristics of engineering plastics, with high torque, high speed, precise temperature control and excellent dispersibility, which can effectively solve the processing difficulties of engineering plastics and help enterprises achieve high-quality, efficient and stable production.
1.2 Core Performance Characteristics of Engineering Plastics
Compared with general plastics and metal materials, engineering plastics have unique comprehensive performance, which determines their wide application in various industrial fields. The core performance characteristics of engineering plastics are mainly reflected in the following five aspects, which also put forward special requirements for their processing technology and equipment:
1.2.1 Excellent Heat Resistance and Cold Resistance
Engineering plastics have a wide temperature adaptation range, which can maintain good mechanical properties (strength, toughness, ጥንካሬ) in both high and low temperature environments. Compared with general plastics, which usually lose their mechanical properties at 80-120℃, most engineering plastics can work stably at 100-250℃, and some special engineering plastics (such as PEEK, PI) can even work at temperatures above 300℃. በተመሳሳይ ጊዜ, engineering plastics also have good cold resistance, which can maintain good toughness at low temperatures (below -40℃), and are not easy to brittle fracture. This performance makes engineering plastics suitable for use in harsh temperature environments, such as automotive engine parts (high temperature) and outdoor electrical equipment (low temperature).
The excellent heat resistance of engineering plastics is mainly due to their special molecular structure (such as aromatic rings, heterocyclic rings) and strong intermolecular forces, which makes them not easy to melt and decompose at high temperatures. ቢሆንም, this also brings certain difficulties to processing: higher processing temperature is required to make them melt and plasticize, and precise temperature control is needed to avoid thermal decomposition.
1.2.2 Good Corrosion Resistance and Durability
Engineering plastics have excellent chemical stability and corrosion resistance, and are not easy to be corroded by acids, alkalis, salts, organic solvents and other chemicals. Compared with metal materials, which are easy to rust and corrode, engineering plastics have longer service life in harsh chemical environments. ለምሳሌ, ፖሊማሚድ (ፒ.ኤ) engineering plastics are resistant to most organic solvents and weak acids and alkalis; ፖሊካርቦኔት (ፒሲ) engineering plastics are resistant to corrosion by non-oxidizing acids and salts; polyphenylene sulfide (ፒ.ፒ.ኤስ) engineering plastics are resistant to corrosion by almost all chemicals except strong oxidizing acids.
በተጨማሪ, engineering plastics have good weather resistance and aging resistance, and are not easy to degrade and age under the action of sunlight, rain, oxygen and other environmental factors, which ensures their long-term stable use in outdoor and harsh environments. This performance makes engineering plastics widely used in chemical equipment, outdoor electrical equipment, automotive exterior parts and other fields.
1.2.3 Easy Processing and High Production Efficiency
Compared with metal materials, engineering plastics have the advantages of easy processing, simple production process and high production efficiency. Metal materials usually need complex processing procedures such as forging, casting, ማሽነሪ, which have high energy consumption, low efficiency and high cost; while engineering plastics can be processed by extrusion, መርፌ መቅረጽ, blow molding and other methods, which can realize mass production, simplify the production process, reduce energy consumption and production cost. ለምሳሌ, the processing cycle of an engineering plastic automotive part by injection molding is only a few seconds to tens of seconds, while the processing cycle of the same metal part may take several hours to several days.
ቢሆንም, engineering plastics also have certain processing difficulties: they are sensitive to overheating and hydrolytic degradation, and are easy to decompose if the processing temperature is too high or the residence time is too long; at the same time, አንዳንድ የምህንድስና ፕላስቲኮች (such as PA) have high water absorption, which affects the processing effect and product quality. Therefore, it is necessary to use professional processing equipment and scientific processing techniques to ensure the processing quality.
1.2.4 Excellent Dimensional Stability and Electrical Insulation
Engineering plastics have good dimensional stability, and the shrinkage rate is small (በተለምዶ 0.3%-1.5%) during processing and use, which can ensure the dimensional accuracy of products and avoid deformation. This performance is particularly important for high-precision parts, such as electrical connectors, automotive precision components, የሕክምና መሳሪያዎች, etc. The good dimensional stability of engineering plastics is mainly due to their high crystallinity, low water absorption (except for some varieties such as PA) and strong intermolecular forces.
በተጨማሪ, most engineering plastics have excellent electrical insulation performance, which can maintain good insulation performance in a wide temperature range and frequency range, and are not easy to conduct electricity and arc. This makes engineering plastics widely used in electrical and electronic fields, such as wiring boards, cable ties, ማገናኛዎች, relays, motors and other electrical components.
1.2.5 Light Weight and High Specific Strength, Outstanding Wear Resistance
Engineering plastics have the characteristics of light weight (density is 1/3-1/5 of metal materials) and high specific strength (strength per unit weight is equivalent to or even higher than that of metal materials). ለምሳሌ, the specific strength of glass fiber reinforced polyamide (PA66+GF30) is higher than that of ordinary carbon steel, which can effectively reduce the weight of products while ensuring the mechanical performance. This performance is particularly important in the automotive, aerospace and other fields that pursue lightweight and energy saving, which can reduce fuel consumption and carbon emissions.
በተመሳሳይ ጊዜ, engineering plastics also have outstanding wear resistance and friction resistance, and the friction coefficient is small, which can be used in the production of wear-resistant parts (such as gears, ተሸካሚዎች, sliding blocks) without additional lubrication or with less lubrication, reducing the maintenance cost of products. ለምሳሌ, polyoxymethylene (ፖም) engineering plastics have excellent wear resistance and are known as “plastic steel”, which is widely used in the production of automotive gears, electrical components and other wear-resistant parts.
1.3 Common Classification of Engineering Plastics
Engineering plastics can be divided into different types according to their chemical structure, performance level and application field. The common classification methods are as follows, which helps to better understand the processing characteristics and application scenarios of different engineering plastics, and select appropriate extrusion equipment and processing techniques:
1.3.1 Classification by Performance Level
According to the performance level, engineering plastics can be divided into general engineering plastics and special engineering plastics.
- General Engineering Plastics: They are the most widely used engineering plastics, with relatively mature production technology, moderate price and good comprehensive performance. The main varieties include polyamide (ፒ.ኤ), ፖሊካርቦኔት (ፒሲ), polyoxymethylene (ፖም), polyethylene terephthalate (ፔት), polybutylene terephthalate (ፒቢቲ), etc. General engineering plastics are mainly used in automotive, electrical and electronic, home appliances and other fields, such as automotive parts, electrical connectors, home appliance shells, etc.
- Special Engineering Plastics: They have more excellent performance (such as higher heat resistance, የዝገት መቋቋም, mechanical properties) than general engineering plastics, but the production technology is complex and the price is high. The main varieties include polyphenylene sulfide (ፒ.ፒ.ኤስ), polyether ether ketone (PEEK), polyimide (PI), polysulfone (PSU), polyethersulfone (PES), etc. Special engineering plastics are mainly used in high-end fields such as aerospace, የሕክምና መሳሪያዎች, new energy, and chemical equipment, such as aerospace components, medical implants, high-temperature resistant electrical components, etc.
1.3.2 Classification by Chemical Structure
According to the chemical structure of the molecular chain, engineering plastics can be divided into polyamide (ፒ.ኤ), ፖሊካርቦኔት (ፒሲ), polyoxymethylene (ፖም), polyester (ፔት, ፒቢቲ), polyphenylene sulfide (ፒ.ፒ.ኤስ), polyether ether ketone (PEEK), etc. Each type of engineering plastic has its own unique performance characteristics and processing requirements:
- ፖሊማሚድ (ፒ.ኤ): Also known as nylon, it has excellent mechanical strength, የመቋቋም ችሎታ ይለብሱ, toughness and chemical resistance, but has high water absorption, which affects the dimensional stability. Common varieties include PA6, PA66, PA11, PA12, etc. It is widely used in automotive parts (gears, ተሸካሚዎች, intake manifolds), electrical connectors, textile fibers, etc.
- ፖሊካርቦኔት (ፒሲ): It has excellent transparency, ተጽዕኖ ጥንካሬ, heat resistance and electrical insulation, but has poor wear resistance and is easy to scratch. It is widely used in electrical and electronic fields (wiring boards, lamp covers), automotive fields (headlamp lenses, instrument panels), medical fields (medical containers), etc.
- ፖሊዮክሳይሚል (ፖም): It has excellent wear resistance, friction resistance, dimensional stability and mechanical strength, and is not easy to absorb water. It is known as “plastic steel” and is widely used in automotive parts (gears, sliding blocks), የኤሌክትሪክ አካላት (switches, ተሸካሚዎች), mechanical parts, etc.
- Polyester (ፔት, ፒቢቲ): PET has excellent transparency, heat resistance and mechanical strength, and is mainly used in fibers, ፊልሞች, bottles and other fields; PBT has excellent chemical resistance, electrical insulation and processing fluidity, and is widely used in electrical and electronic fields (ማገናኛዎች, relays), አውቶሞቲቭ ክፍሎች, etc.
- Polyphenylene Sulfide (ፒ.ፒ.ኤስ): It has excellent heat resistance (long-term use temperature up to 200-220℃), የዝገት መቋቋም, flame retardancy and electrical insulation, but has poor toughness. It is widely used in high-temperature resistant electrical components, automotive engine parts, chemical equipment, etc.
- Polyether Ether Ketone (PEEK): It has excellent comprehensive performance, long-term use temperature up to 250-300℃, ጥሩ የዝገት መቋቋም, የሜካኒካል ጥንካሬ እና ባዮኬሚካላዊነት. እሱ በዋነኝነት እንደ ኤሮስፔስ ባሉ ከፍተኛ-ደረጃ መስኮች ውስጥ ጥቅም ላይ ይውላል, medical implants, እና ከፍተኛ ሙቀት መቋቋም የሚችሉ የኤሌክትሪክ ክፍሎች.
1.3.3 በመተግበሪያ መስክ ምደባ
በማመልከቻው መስክ መሠረት, የምህንድስና ፕላስቲኮች በአውቶሞቲቭ ደረጃ የምህንድስና ፕላስቲኮች ሊከፋፈሉ ይችላሉ።, የኤሌክትሪክ-ደረጃ የምህንድስና ፕላስቲኮች, የሕክምና-ምህንድስና ፕላስቲኮች, ኤሮስፔስ-ደረጃ የምህንድስና ፕላስቲኮች, etc. የተለያዩ የመተግበሪያ መስኮች የምህንድስና ፕላስቲኮች አፈፃፀም ላይ የተለያዩ መስፈርቶች አሏቸው. ለምሳሌ, አውቶሞቲቭ ደረጃ የምህንድስና ፕላስቲኮች ጥሩ የሙቀት መቋቋም ያስፈልጋቸዋል, ተጽዕኖ ጥንካሬ እና የአየር ሁኔታ መቋቋም; የኤሌክትሪክ ምህንድስና ፕላስቲኮች ጥሩ የኤሌክትሪክ መከላከያ እና የነበልባል መዘግየት ያስፈልጋቸዋል; የሕክምና ደረጃ የምህንድስና ፕላስቲኮች ጥሩ ባዮኬሚካላዊ እና ማምከን ያስፈልጋቸዋል; aerospace-grade engineering plastics require good high-temperature resistance, low weight and high strength.
2. Core Processing Technology of Engineering Plastics: Twin-Screw Extrusion Technology
Engineering plastics processing mainly includes extrusion, መርፌ መቅረጽ, መንፋት መቅረጽ, molding and other methods, among which twin-screw extrusion technology is the core technology for the production of engineering plastic compounds (such as modified engineering plastics, reinforced engineering plastics) and semi-finished products (such as pipes, አንሶላዎች, fibers). Compared with single-screw extrusion technology, twin-screw extrusion technology has the advantages of strong shearing force, good mixing effect, precise temperature control, short residence time and strong adaptability to raw materials, which can effectively solve the processing difficulties of engineering plastics (such as sensitivity to overheating and hydrolytic degradation, poor mixing effect, low processing efficiency) and ensure the quality of engineering plastic products.
2.1 Processing Difficulties of Engineering Plastics and Requirements for Extrusion Equipment
As mentioned earlier, engineering plastics have excellent comprehensive performance, but their processing difficulty is also higher than that of general plastics, mainly due to their special molecular structure and performance characteristics. The main processing difficulties of engineering plastics and the corresponding requirements for extrusion equipment are as follows:
2.1.1 Sensitivity to Overheating and Hydrolytic Degradation
Most engineering plastics (such as PA, ፒቢቲ, ፒ.ፒ.ኤስ) are sensitive to overheating and hydrolytic degradation. If the processing temperature is too high or the residence time in the extruder is too long, the molecular chain of the engineering plastic will break, resulting in thermal decomposition, which will reduce the mechanical properties, heat resistance and other performance of the product, and even cause discoloration, carbonization and other defects. በተጨማሪ, አንዳንድ የምህንድስና ፕላስቲኮች (such as PA) have high water absorption, and the moisture in the material will cause hydrolytic degradation during the high-temperature processing process, affecting the product quality.
This puts forward two key requirements for extrusion equipment: አንደኛ, precise temperature control capacity, which can strictly control the processing temperature within the optimal range of engineering plastics, avoid local overheating, and the temperature control precision should reach ±1℃; ሁለተኛ, short residence time, 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 (በተለምዶ 1-5 ደቂቃዎች) and precise temperature control, which are more suitable for engineering plastics processing than single-screw extruders (residence time 5-10 ደቂቃዎች).
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, የካርቦን ፋይበር, talc, የእሳት ነበልባል መከላከያዎች, ተኳሃኝዎች) to improve the performance of the product (such as reinforcing, toughening, flame retardant). ለምሳሌ, 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. በተጨማሪ, the modular design of the twin-screw can freely combine different screw elements (such as conveying elements, mixing elements, shearing elements) 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.
ይህ የጭስ ማውጫው ጠመዝማዛ እና በርሜል ከፍተኛ ጥራት ካለው የመልበስ መከላከያ ቁሳቁሶች ተሠርቶ በላቁ የማኑፋክቸሪንግ ቴክኖሎጂ እንዲሠራ ይፈልጋል ።. የኛ HTS ተከታታዮች ከውጪ የሚመጣ መልበስን የሚቋቋም ቅይጥ ብረት ለስክሩ እና በርሜል ይቀበላሉ።, እና የቢሚታል ድብልቅ ህክምና ወይም የሌዘር ክላዲንግ ህክምናን ያካሂዱ, የጭረት እና በርሜል የመልበስ መቋቋም እና የዝገት መቋቋምን በእጅጉ ያሻሽላል, እና የተጠናከረ የኢንጂነሪንግ ፕላስቲኮችን ከከፍተኛ ጥንካሬ ማሻሻያዎች ጋር ማስማማት ይችላል።.
2.1.4 ፈሳሽነት እና የግፊት መቆጣጠሪያን በማቀነባበር ላይ ከፍተኛ መስፈርቶች
አንዳንድ የምህንድስና ፕላስቲኮች (እንደ ፒ.ፒ.ኤስ, PEEK) ከፍተኛ viscosity እና ደካማ ሂደት ፈሳሽ አላቸው, የኤክስትራክተሩ ጠንካራ የማስተላለፊያ አቅም እና የግፊት መቆጣጠሪያ አቅም እንዲኖረው የሚጠይቀው የመልቀቂያውን ለስላሳ ሂደት ለማረጋገጥ ነው።. 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; at the same time, the extruder is equipped with a high-precision pressure sensor, 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, which involves the interaction of multiple factors such as temperature, ግፊት, shear force and time. 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, pipes, አንሶላዎች, fibers) through the die head. The specific working principle and process flow are as follows:
2.2.1 Raw Material Pretreatment
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 (such as PA, ፒሲ, ፖም), modifiers (such as glass fiber, የካርቦን ፋይበር, talc, የእሳት ነበልባል መከላከያዎች), ተኳሃኝዎች, lubricants and other additives. The pretreatment steps are as follows:
- Drying Treatment: Most engineering plastics (such as PA, ፒቢቲ, ፒ.ፒ.ኤስ) have high water absorption, እና በጥሬ እቃዎች ውስጥ ያለው እርጥበት ከፍተኛ ሙቀት በሚፈጠርበት ጊዜ የሃይድሮሊክ መበላሸትን ያመጣል, የምርት ጉድለቶችን ያስከትላል (እንደ አረፋዎች, ስንጥቆች, የተቀነሰ ሜካኒካዊ ባህሪያት). Therefore, ጥሬ እቃዎቹ ከማቀነባበራቸው በፊት መድረቅ አለባቸው. የማድረቅ ሙቀት እና ጊዜ የሚወሰነው እንደ የምህንድስና ፕላስቲክ ዓይነት ነው: ለምሳሌ, PA6 በ 80-100 ℃ ይደርቃል ለ 4-6 ሰዓታት, PA66 በ 100-120 ℃ ደርቋል 6-8 ሰዓታት, PBT በ 120-140 ℃ ይደርቃል ለ 2-4 ሰዓታት, PPS በ 150-160 ℃ ደርቋል 3-5 ሰዓታት. የደረቁ ጥሬ ዕቃዎች እርጥበት ይዘት ከዚህ በታች ቁጥጥር ሊደረግበት ይገባል 0.1%-0.2%.
- ፕሪሚክስ ሕክምና: በቀመር ጥምርታ መሰረት, የደረቀው የምህንድስና የፕላስቲክ ሙጫ, መቀየሪያዎች እና ተጨማሪዎች ለቅድመ ማደባለቅ ከፍተኛ ፍጥነት ባለው ድብልቅ ውስጥ ይቀመጣሉ።. 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. The mixing speed is generally 800-1200 ራፒኤም, and the mixing time is 5-10 ደቂቃዎች. 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.
- Crushing and 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. The particle size of the crushed raw materials should be controlled at 20-40 ጥልፍልፍ.
2.2.2 መመገብ እና ማስተላለፍ
ቀድሞ የተደባለቁ ጥሬ ዕቃዎች ወደ መንታ-ስክራው አውጭው በዊንች መጋቢ ወይም በቀበቶ መጋቢ በኩል ይላካሉ።. የኤክስትራክተሩ የመመገቢያ መሳሪያ ብዙውን ጊዜ ድግግሞሽ የመቀየር ፍጥነት መቆጣጠሪያ ተግባር የተገጠመለት ነው።, ቁሳቁሶቹ በተረጋጋ ሁኔታ እና ወጥ በሆነ መልኩ ወደ መውጫው ጉድጓድ ውስጥ መግባታቸውን ለማረጋገጥ የመመገቢያውን ፍጥነት እንደ ስፒው ፍጥነት እና እንደ መውጫ ፍጥነት ማስተካከል የሚችል።, የቁሳቁስ ክምችት ወይም በቂ ያልሆነ አመጋገብን ማስወገድ. የመመገቢያ ገንዳው በአመጋገብ ወቅት ጥሬ እቃዎች እንደገና እርጥበት እንዳይወስዱ ለመከላከል በማድረቂያ መሳሪያ የተገጠመለት ነው.

2.3 የኢንጂነሪንግ ፕላስቲኮች መንትያ-ስክሩ ኤክስትራክሽን ተፅእኖን የሚነኩ ቁልፍ ምክንያቶች
መንትያ-ስክሩ መውጣት ተጽእኖ በቀጥታ የምህንድስና የፕላስቲክ ምርቶችን ጥራት እና አፈፃፀም ይነካል. የ extrusion ውጤት ላይ ተጽዕኖ የሚያሳድሩ ብዙ ምክንያቶች አሉ, በዋናነት የጥሬ ዕቃ ባህሪያትን ጨምሮ, የቀመር ጥምርታ, የፕሪሚክስ ውጤት, የኤክስትራክሽን መለኪያዎች እና የሞት ጭንቅላት መዋቅር. እነዚህን ቁልፍ ነገሮች መቆጣጠር እና ሳይንሳዊ ማስተካከያዎችን ማድረግ የ extrusion ውጤት መረጋጋት እና የምርት ጥራት ወጥነት ማረጋገጥ ይችላል.
2.3.1 ጥሬ እቃ ባህሪያት
ዓይነት, ቅንጣት መጠን, የእርጥበት መጠን እና የጥሬ እቃዎች ንፅህና በኤክስትራክሽን ተጽእኖ ላይ ከፍተኛ ተጽዕኖ ያሳድራል. ለምሳሌ, የምህንድስና የፕላስቲክ ሙጫ እና ማሻሻያ ቅንጣት መጠን አንድ ወጥ መሆን አለበት።; የንጥሉ መጠኑ ያልተስተካከለ ከሆነ, ወደ ወጣ ገባ ማቅለጥ እና ቁሳቁሶች መቀላቀልን ያመጣል. የጥሬ ዕቃዎች እርጥበት ይዘት ከዚህ በታች ጥብቅ ቁጥጥር ሊደረግበት ይገባል 0.1%-0.2%; የእርጥበት መጠኑ በጣም ከፍተኛ ከሆነ, በምርቱ ውስጥ ያሉ ንጥረ ነገሮች እና አረፋዎች የሃይድሮሊክ መበስበስን ያስከትላል. The purity of raw materials is also very important; ጥሬ ዕቃዎች ውስጥ ቆሻሻዎች (such as metals, stones, አቧራ) will not only affect the product quality, but also wear the screw and barrel of the extruder, and even cause equipment blockage.
2.3.2 Formula Ratio
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. ለምሳሌ, መጨመር 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. The type and dosage of additives also need to be reasonably matched: 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, improve processing 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 Premixing Effect
Premixing is the foundation of extrusion processing. The uniformity of premixing directly affects the mixing and dispersing effect of modifiers during extrusion. If the premixing is uneven, 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. To ensure the premixing effect, it is necessary to control the mixing speed, mixing time and mixing temperature: the mixing speed is 800-1200 ራፒኤም, the mixing time is 5-10 ደቂቃዎች, and the mixing temperature is controlled at 40-60℃ (ተገቢው የሙቀት መጠን ተጨማሪዎችን ማጣበቅን ያሻሽላል እና ተመሳሳይ ድብልቅን ያበረታታል።).
2.3.4 የኤክስትራክሽን መለኪያዎች
የማስወጫ መለኪያዎች በውጫዊ ተፅእኖ ላይ ተጽዕኖ የሚያሳድሩ በጣም አስፈላጊ ነገሮች ናቸው, በዋናነት የማሽከርከር ፍጥነትን ጨምሮ, የኤክስትራክሽን የሙቀት መጠን እና የግፊት ግፊት.
- የፍጥነት ፍጥነት: ለኢንጂነሪንግ ፕላስቲኮች የመንትዮቹ-ስፒር አውጭዎች የፍጥነት መጠን በአጠቃላይ ከ ይለያያል 100 ወደ 1000 ራፒኤም. የእኛ የHTS ተከታታዮች ከፍተኛ ፍጥነት ሊደርሱ ይችላሉ። 1000 ራፒኤም. የፍጥነቱ ከፍ ያለ ነው።, በእቃዎቹ የተቀበለው የመቁረጥ ኃይል እና የግጭት ኃይል የበለጠ, የመቀየሪያዎቹ መቀላቀል እና መበታተን የተሻለ ይሆናል።, እና ከፍተኛ የምርት ውጤታማነት. ቢሆንም, የማሽከርከሪያው ፍጥነት በጣም ከፍተኛ ከሆነ, በ extrusion አቅልጠው ውስጥ ቁሳቁሶች የመኖሪያ ጊዜ በጣም አጭር ነው, ሙጫው ያልተሟላ መቅለጥን ያስከትላል, በቂ ያልሆነ የቁሳቁሶች ድብልቅ, እና ያልተስተካከለ የምርት ጥራት; የማሽከርከሪያው ፍጥነት በጣም ዝቅተኛ ከሆነ, የመቁረጥ ኃይል እና የግጭት ኃይል በቂ አይደሉም, መቀየሪያዎቹ ሙሉ በሙሉ ሊበታተኑ አይችሉም, እና የምርት ውጤታማነት ዝቅተኛ ነው. የፍጥነቱ ፍጥነት እንደ ኢንጂነሪንግ ፕላስቲክ አይነት እና እንደ መቀየሪያ አይነት መስተካከል አለበት።: ለከፍተኛ- viscosity የምህንድስና ፕላስቲኮች (እንደ ፒ.ፒ.ኤስ, PEEK), በቂ መቅለጥ እና መቀላቀልን ለማረጋገጥ ዝቅተኛ የፍጥነት ፍጥነት ያስፈልጋል; for reinforced engineering plastics (such as glass fiber reinforced PA), a higher screw speed is needed to ensure the uniform dispersion of glass fiber.
- Extrusion Temperature: 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. 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 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 modifiers; 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 semi-finished products. The temperature control precision should reach ±1℃ to avoid local overheating and thermal decomposition of the material.
- Extrusion Pressure: The extrusion pressure of engineering plastics twin-screw extrusion generally ranges from 5 to 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. ከፍ ያለ የኤክስትራክሽን ግፊት, the better the mixing and dispersing effect of materials, and the denser the product. ቢሆንም, if the pressure is too high, የኃይል ፍጆታን እና የመሳሪያውን ማልበስ ይጨምራል, and even cause the die head to block; ግፊቱ በጣም ዝቅተኛ ከሆነ, the materials cannot be fully compressed and mixed, the product is loose, and the performance is unstable. 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 የዳይ ጭንቅላት መዋቅር
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. የምህንድስና የፕላስቲክ ውህዶች ለማምረት (ጥራጥሬዎች), 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
በጥናቱ ውስጥ ለረጅም ጊዜ ቆይተናል, 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, high viscosity) 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, High Production Efficiency
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 (HTS PLUS ተከታታይ እና HTS SUPER ተከታታይ) ወይም ከዋና ዋና አውሮፓውያን አምራቾች የመጣ (HTS BASIC ተከታታይ), 14Nm/ሴሜ³ የሆነ የማሽከርከር ኃይል ያለው, ከተራ መንትያ ጠመዝማዛ አውጭዎች በጣም ከፍ ያለ ነው። (አጠቃላይ ጉልበት 8-12Nm/ሴሜ³ ነው።). ከፍተኛ የማሽከርከር ንድፍ አውጪው ከፍተኛ viscosity የምህንድስና የፕላስቲክ ቁሳቁሶችን በተረጋጋ ሁኔታ ማስተላለፍ መቻሉን ያረጋግጣል, የቁሳቁስ ክምችት እና የመሳሪያዎች መዘጋትን ያስወግዱ, እና የማስወጣት ሂደቱን መረጋጋት ያሻሽሉ.
በተመሳሳይ ጊዜ, የ HTS ተከታታይ ኤክሰሮች ከፍተኛ ፍጥነት ያለው ንድፍ አላቸው, በከፍተኛ ፍጥነት እስከ 1000rpm. ከፍተኛ ፍጥነቱ ጠንካራ የመቁረጥ ኃይል እና የመቀላቀል ኃይልን ሊያመነጭ ይችላል።, which can fully break the agglomerates of modifiers, ማስተካከያዎቹን በሬንጅ ማትሪክስ ውስጥ አንድ ወጥ በሆነ መልኩ እንዲበታተኑ ያድርጉ, እና የማደባለቅ እና የመበታተን ውጤትን ያሻሽሉ. በተጨማሪ, የከፍተኛ ፍጥነት ንድፍ እንዲሁ የምርት ውጤታማነትን በእጅጉ ያሻሽላል: ከተራ extruders ጋር ሲነጻጸር, 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 ደቂቃዎች, which is much shorter than that of ordinary twin-screw extruders (5-10 ደቂቃዎች) and single-screw extruders (10-15 ደቂቃዎች). 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.
በተጨማሪ, የ HTS ተከታታይ extruders ጠመዝማዛ ሞዱል ንድፍ ይቀበላል, እና እንደ የምህንድስና ፕላስቲክ ዓይነት የተለያዩ የጭረት ክፍሎች በነፃነት ሊጣመሩ ይችላሉ።, የቁሳቁስን የመኖሪያ ጊዜ የበለጠ ማስተካከል የሚችል, የተለያዩ የኢንጂነሪንግ ፕላስቲኮች በሂደቱ ወቅት ትክክለኛውን የመኖሪያ ጊዜ ማግኘት እንደሚችሉ ማረጋገጥ.
3.1.3 ትክክለኛ የሙቀት መቆጣጠሪያ, የተረጋጋ አፈጻጸም
የኤችቲኤስ ተከታታዮች የላቀ የማሰብ ችሎታ ያለው የሙቀት መቆጣጠሪያ ሥርዓትን ይቀበላሉ።, የእያንዳንዱን የበርሜል ክፍል እና የሟች ጭንቅላትን የሙቀት መጠን በትክክል መቆጣጠር የሚችል. የሙቀት መቆጣጠሪያ ትክክለኛነት ± 1 ℃ ሊደርስ ይችላል, which can strictly control the processing temperature within the optimal range of engineering plastics, የአካባቢያዊ ሙቀትን እና የእቃውን የሙቀት መበስበስ ያስወግዱ. የሙቀት መቆጣጠሪያ ስርዓቱ በእውነተኛ ጊዜ ክትትል እና የማንቂያ ተግባር የተገጠመለት ነው: if the temperature of any section exceeds the set range, the system will issue an alarm prompt in time, and even automatically adjust the heating power or shut down the equipment if necessary, to avoid equipment failure and product quality problems.
በተጨማሪ, the barrel of the HTS series extruders 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 product.
3.1.4 Excellent Mixing and Dispersing Effect
The HTS series extruders adopt an intermeshing co-rotating twin-screw 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 modifiers (such as glass fiber, የካርቦን ፋይበር, talc), make the modifiers uniformly dispersed in the engineering plastic resin matrix, and ensure the mixing and dispersing effect. The mixing uniformity of the HTS series extruders can reach more than 95%, ከተራ መንትያ ጠመዝማዛ አውጭዎች በጣም ከፍ ያለ ነው። (85%-90%).
The screw of the HTS series extruders adopts a modular design, and different types of screw elements (such as conveying elements, mixing elements, shearing elements) can be freely combined according to the type of engineering plastic and modifier. ለምሳሌ, when processing reinforced engineering plastics with glass fiber, more shearing elements can be configured to enhance the shearing effect and ensure the uniform dispersion of glass fiber; when processing engineering plastics with high viscosity (እንደ ፒ.ፒ.ኤስ), more mixing elements can be configured to improve the mixing effect and ensure the uniform viscosity of the material.
