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。

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 e 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 e, toys and various containers. Low foaming ABS can replace wood, suitable for building materials, furniture and household goods.
