成型性能
无定形材料,流动性中等,吸湿大,必须充分干燥,表面要求光泽的塑件须长时间预热干燥80-90度,3小时;
宜取高料温,高模温,但料温过高易分解(分解温度为>270度).对精度较高的塑件,模温宜取50-60度,对高光泽.耐热塑件,模温宜取60-80度;
如需解决夹水纹,需提高材料的流动性,采取高料温、高模温,或者改变入水位等方法;
如成形耐热级或阻燃级材料,生产3-7天后模具表面会残存塑料分解物,导致模具表面发亮,需对模具及时进行清理,同时模具表面需增加排气位置;
冷却速度快,模具浇注系统应以粗,短为原则,宜设冷料穴,浇口宜取大,如:直接浇口,圆盘浇口或扇形浇口等,但应防止内应力增大,必要时可采用调整式浇口。模具宜加热,应选用耐磨钢;
料温对塑件质量影响较大,料温过低会造成缺料,表面无光泽,银丝紊乱料温过高易溢边,出现银丝暗条,塑件变色起泡;
用途
ABS树脂的最大应用领域是汽车、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。
