发生火灾当然是件坏事,然而在一定条件下也能转化为好事。硝化棉就是在着火事故中发明的。 1070年,英国有位科学家在实验室做试验时,由于一时疏忽,不慎将硝酸试剂滴洒到试验台上,他顺手就抓起一块棉纱,不加思索地去擦试台面,然后习惯地随手丢入废物箱中。可不一会儿,废物箱中的那块棉纱却出人意外地起火燃烧了。 这位科学家从棉纱着火的现象中得到了启发,研究发明了硝化棉火药。其实,人们对硝化棉火药并不陌生。硝化棉又名硝化纤维素,通常含氮量在12.5％以
Of course, a fire is a bad thing, but under certain conditions it can turn into a good thing. Nitrocellulose was invented in a fire accident. In 1070, when a scientist in Britain conducted a test in a laboratory, he inadvertently dripped the nitric acid reagent onto the test bench because of a moment of negligence. He smoothly grabbed a piece of cotton yarn and went to scrape the tabletop without thinking, Throw in the waste box. In a moment, the cotton yarn in the waste bin burned unexpectedly. The scientist, inspired by the phenomenon of cotton yarn fire, researched and invented nitrocellulose gunpowder. In fact, people are familiar with nitrocellulose gunpowder. Nitrocellulose, also known as nitrocellulose, usually contains 12.5% nitrogen
