改性ABS原材料
ABS是一种无定形聚合物。由于分子中存在氢基团(-CN),它具有很高的吸水率,吸水率高达0.45%。塑料加工所需的含水量小于0.3%,因此加工前需达到70~80。在高温烘箱中干燥材料2至4小时(材料层厚度为2.5至4厘米)。其熔体粘度高,不易流动,成型温度高,压力高,速度快。成型模的流道和浇口应适当大,但由于ABS树脂含有橡胶成分(丁二烯),高加工温度不会增加其流动性,相反,会导致橡胶分解并降低其流动性。因此,加工过程中应严格控制温度在允许范围内。螺杆注塑机的成型温度一般控制在后端150~170℃,中间温度165~180℃,前端180~200℃,喷嘴170~180℃。零件成型后应进行退火处理。一般来说,让它在70°C的热空气中静置2到4小时。

ABS processing attention
ABS is an amorphous polymer. Due to the presence of hydrogen groups (-CN) in the molecule, it has high water absorption and the water absorption rate is as high as 0.45%. The water content of plastic processing requires less than 0.3%, so it needs to be 70~80 before processing. Dry the material in a high-temperature oven for 2 to 4 hours (the thickness of the material layer is 2.5 to 4 cm). Its melt viscosity is high, it is not easy to flow, the molding temperature must be high, the pressure must be high, and the speed must be high. The runner and gate of the molding die should be appropriately large, but because the ABS resin contains rubber components (butadiene), High processing temperature will not increase its fluidity, on the contrary, it will cause the rubber to decompose and reduce its fluidity. Therefore, the temperature should be strictly controlled within the allowable range during processing. The molding temperature of the screw injection molding machine is generally controlled at 150~170℃ in the rear end, 165~180℃ in the middle, 180~200℃ in the front end, and 170~180℃ in the nozzle. The parts should be annealed after forming. Generally, let it stand for 2 to 4 hours in hot air at 70°C.
