成型特
1、无定形料,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。
2、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。
3、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。
4、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。
5、强度较高,耐冲击能力强。

详细说明:of post, both were called away, the one twenty-five, the other twenty-two; their brief generation became extinct, their short-lived house fell with them; and ‘in these lawless parts and lawless times’— the words are my grandfather’s — their property was stolen or became involved. Many years later, I understand some small recovery to have been made; but at the moment almost the whole means of the family seem to have perished with the young merchants. On the 27th April, eleven days after Hugh Stevenson, twenty-nine before Alan, died David Lillie, the Deacon of the Wrights; so that mother and son were orphaned in one month.
