一、硝化纤维的爆炸实验有不少参考书介绍此实验时,建议采用把硝化棉装于试管中,塞上木塞,然后加热。但是操作时曾有人因木塞塞得过紧而导致试管爆裂,此操作不够安全,所以需要改进。今改用一根长约40厘米、内径约0.5厘米的玻璃管作“炮膛”,用绿豆作“炮弹”,一端用姆指堵住,一端敞口,在装入的一小团硝化棉处用酒精灯加热,由于炮膛深,一端又是敞口,所以“炮弹”可射得很远,而又没有危险。 First, the nitrification test explosion There are many reference books to introduce this experiment, it is recommended to use nitrocellulose mounted in test tubes, stuffed with cork, and then heated. However, during operation, someone had to burst the test tube because of the jamming of the plug. This operation is not safe enough and needs improvement. Now use a 40 cm long, about 0.5 cm diameter glass tube as a “barrel” with mung beans as a “cannonball”, one end with a thumb to block, open at one end, in a small group of loaded nitrocellulose With the alcohol lamp heating, due to the deep bore, one end is open, so “shells” can be fired far away, but without danger.
