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。此外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 a variety of water pipes, trachea, lubricants and fuel oil pipeline; Plates and sheets can be used for flooring, furniture, pool troughs, filters, wall partitions and thermoforming or vacuum forming. The ratio of length to diameter of screw in extruder is usually 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. The temperature of barrel is 150 ~ 160 ° C in Hopper, 180 ~ 190 ° C in front of barrel, the die head temperature is 185 ~ 195 ° C, the die temperature is 180 ~ 200 ° C, and the blow molding temperature can be controlled between 140 ~ 180 ° C. Application Scope the big application field of ABS resin is automobile, electronic and electrical appliances and building materials. Automotive applications include dashboard, body panels, interior trim panels, steering wheel, soundproof panels, door locks, bumpers, ventilation pipes and many other components. In the electrical field is widely used in refrigerators, television sets, washing machines, air conditioners, computers, photocopiers and other electronic appliances. Building materials, Abs Pipe, ABS sanitary ware, ABS decorative 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 instrumentation industry. 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, instrument panel, basin safety cap, etc. . In home appliances and home electronic equipment application prospects are broader, such as television sets, recorders, refrigerators, refrigerators, washing machines, air conditioners, vacuum cleaners and a variety of small home appliances; Daily necessities are shoes, bags, various travel boxes, office equipment, toys and various containers. Low foaming ABS can replace wood, suitable for building materials, furniture and household goods.
