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:With these two brothers my story begins. Their deaths were simultaneous; their lives unusually brief and full. Tradition whispered me in childhood they were the owners of an islet near St. Kitts; and it is certain they had risen to be at the head of considerable interests in the West Indies, which Hugh managed abroad and Alan at home, at an age when others are still curveting a clerk’s stool. My kinsman, Mr. Stevenson of Stirling, has heard his father mention that there had been ‘something romantic’ about Alan’s marriage: and, alas! he has forgotten what. It was early at least. His wife was Jean, daughter of David Lillie, a builder in Glasgow, and several times ‘Deacon of the Wrights’: the date of the marriage has not reached me; but on 8th June 1772, when Robert, the only child of the union, was born, the husband and father had scarce passed, or had not yet attained, his twentieth year. Here was a youth making haste to give hostages to fortune. But this early scene of prosperity in love and business was on the point of closing.
