虾滑三角塑料袋

详细说明:

1845年,居住在瑞士西北部城市巴塞尔的化学家塞伯坦一次在家中做实验时,不小心碰到了桌上的浓硫酸和浓硝酸,他匆促拿起妻子的布围裙去擦洗桌上的混合酸。忙乱之后,他将围裙挂到炉子边烤干,不料围裙“噗”的一声烧了起来,顷刻间化为灰烬。塞伯坦带着这个“重大发现”回到实验室,不断重复发作“事端”。通过屡次实验,塞伯坦终于找到了原因:本来布围裙的主要成分是纤维素,它与浓硝酸及浓硫酸的混合液触摸,生成了硝酸纤维素脂,这就是后来使用广泛的硝化纤维。

In 1845, a chemist living in Basel, Northwestern Switzerland, an chemist at his home, accidentally touched the concentrated sulfuric acid and concentrated nitric acid on the table, and he hurried to pick up his wife's apron to scrub the mixed acid on the table. After the bustle, he hung his apron to the stove and dried it, but the apron burned up and instantly turned to ashes. With the great discovery, he went back to the lab and repeated the attack. Through repeated experiments, he finally found the reason: the main ingredient of the original cloth apron was cellulose, which was touched with a mixture of concentrated nitric acid and concentrated sulfuric acid to produce nitrocellulose fat, which was later used in a wide range of nitrocellulose.
