ABS挤出工艺
挤出。ABS生产棺材、板材、片材、及型材等制品，管材可用于各种水管、气管、润滑油及燃料油的输送管；板材、片材可用于地板、家具、池槽、过滤器、墙壁隔层及热成型或真空成型。挤出机的螺杆长径比通常比较高，L/D为18~22之间，压缩比为（2.5~3.0）：1，宜用渐变型带鱼头螺杆，料筒温度分别为：料斗部150~160℃，料筒前部180~190℃，模头温度185~195℃，模具温度180~200℃，吹塑成型温度可控制在140~180℃之间。
应用范围
ABS树脂的大应用领域是汽车、电子电器和建材。汽车领域的使用包括汽车仪表板、车身外板、内装饰板、方向盘、隔音板、门锁、保险杠、通风管等很多部件。在电器方面则广泛应用于电冰箱、电视机、洗衣机、空调器、计算机、复印机等电子电器中。建材方面，ABS管材、ABS卫生洁具、ABS装饰板广泛应用于建材工业。ABS还广泛的应用于包装、家具、体育和娱乐用品、机械和仪表工业中。
ABS树脂广泛应用于汽车工业、电器仪表工业和机械工业中，常作齿轮，汽车配件，挡泥板，扶手，冰箱内衬，叶片，轴承，把手，管道，接头，仪表壳，仪表板，盆安全帽等；在家用电器和家用电子设备的应用前景更广阔，如电视机、收录机、冰箱、冷柜、洗衣机、空调机、吸尘器和各种小家电器材；日用品有鞋、包、各种旅游箱、办公设备、玩具及各种容器等。低发泡的ABS能代替木材，适合作建材，家具和家庭用品。
ABS extrusion process extrusion. ABS production coffin, plate,sheet, and profiles and other products, pipe can be used in avariety of water pipes, trachea, lubricants and fuel oil pipeline;Plates and sheets can be used for flooring, furniture, pooltroughs, filters, wall partitions and thermoforming or vacuumforming. The ratio of length to diameter of screw in extruder isusually high, L/D is 18 ~ 22, compression ratio is (2.5 ~ 3.0) : 1.It is suitable to use gradual type screw with fish head. Thetemperature of barrel is 150 ~ 160 ° C in Hopper, 180 ~ 190 ° C infront of barrel, the die head temperature is 185 ~ 195 ° C, the dietemperature is 180 ~ 200 ° C, and the blow molding temperature canbe controlled between 140 ~ 180 ° C. Application Scope the bigapplication field of ABS resin is automobile, electronic andelectrical appliances and building materials. Automotiveapplications include dashboard, body panels, interior trim panels,steering wheel, soundproof panels, door locks, bumpers, ventilationpipes and many other components. In the electrical field is widelyused in refrigerators, television sets, washing machines, airconditioners, computers, photocopiers and other electronicappliances. Building materials, Abs Pipe, ABS sanitary ware, ABSdecorative plate is widely used in the building materials industry.In addition, ABS is also widely used in packaging, furniture,sports and entertainment supplies, machinery and instrumentationindustry. ABS resin is widely used in automotive industry,electrical instrument industry and mechanical industry, often gear,auto parts, fenders, handrails, refrigerator lining, blades,bearings, handles, pipes, joints, instrument shell, instrumentpanel, basin safety cap, etc. . In home appliances and homeelectronic equipment application prospects are broader, such astelevision sets, recorders, refrigerators, refrigerators, washingmachines, air conditioners, vacuum cleaners and a variety of smallhome appliances; Daily necessities are shoes, bags, various travelboxes, office equipment, toys and various containers. Low foamingABS can replace wood, suitable for building materials, furnitureand household goods.
