为什么502胶水能用热水洗掉？？？？？急急急急急！！！！求原理！！！！

Question

快啊！！！！明天交作业了！！！！！

Answer 1

502胶水应该不溶于水的， 但是热水温度高，超过了胶水的融点！！！！ 固体就变成液体了，也就滑溜溜的从你手上跑走了。。。。so easy 哪里粘住热哪里。。哦也·····················································································································································································································································································································································································································································································································································································

Answer 2

502胶水本身是无水体系，主要成分是α－氰基丙烯酸乙酯，在水的催化下可发生加聚反应而凝固成固体，而热水只是加快这一反应。

Answer 3

可以用湿的热毛巾在粘502那里。十几分钟后固化的502就会变软，就可以清除了。还有可以在有502的地方再滴上一滴502，固化了的502也会变软，这样子用毛巾也能除去 衣服上的，可用热水浸泡，泡软后迅速搓洗漂洗可去。 手打 求采纳

Answer 4

1、用香蕉水滴在胶水渍上，同时用旧牙刷不断搅刷，待胶水迹变软脱下，再用清水漂净，反覆刷洗，刷净为止。
在有胶水痕迹的衣物背面垫上吸水布，然后往胶水痕迹上涂些白醋，最后用棉花蘸水擦洗干净

2、 在原处滴上502使原来的502融化，然后迅速用水洗掉，很灵的！

3 、用绝缘油，倒点变压器里的绝缘油在桌上，502胶水很快变软，可以很快搓掉了。

4、502胶水是一种树脂胶，只要用溶解树脂的有机溶剂就可以，比如丙酮。
但吸入丙酮有毒，注意使用方法，可以把粘胶的部分塞到瓶子里。据说放到冰箱中冷冻，胶也会掉下来，可以先试一下。

5、小面积粘上502胶水,只要用热水浸泡一下就可以，如果大面积沾上502胶水,涂上丙酮，大约等5～10分钟就可以除去。本回答被提问者和网友采纳
