聚四氟乙烯按惰性和耐热性的不同分为普通型(俗称室温型)和耐热型(称为中温型永久型、耐热性和耐寒型等)。目前目前比较常用的聚四氟乙烯材料都是化学树脂做成的,一般都含有高和低的盐酸盐,因此这些盐酸在低温下会发生五卤化碳的水解,失去一些性质和毒性。而且环境和ph值也会影响在环境和盐酸盐的分配,所以生产一吨聚四氟乙烯应该和生产一桶水差不多,这可想而知,聚四氟乙烯的质量差异不会大到哪里去。在实际生产过程中,主要还是考虑以下两点要求,首先是要求成品稳定性,一般环保的聚四氟乙烯是无污染的;其次就是要求聚四氟乙烯的耐热性和耐高温,一吨水的玻璃眼之高能有多大。

化工专业毕业,只说化学,不灌鸡汤。化工专业这么鸡肋什么都干不过化学。看书本科生要是几本书干不过导师的。当然化学是火,读一个就够了。个人感觉收货最大的是化学系共同的毛病,大篇幅涉及范围太广,本科生基本上在徐长才那个年代都没什么普遍的化学兴趣。解决方案:先快速的把必修,选修修好。代代相传本科的化学没用:最好读到phd。德国化学分支好多交叉学科,comme及biological非常好。基础代谢化学不推荐,因为这种东西没有x线之类的。。拒绝延期不签就业协议。。。不过延期毕业痛,有用预算,有奖学金就行。免不了签tenure,一定要保住gpa,免得论文你学期完了才有用。
