1954年第4期“化学通报”所刊登朱银福同志自制氧炔吹管的经验,经我们试作效果不够好,在起初几十秒钟时可得到良好的结果。时间再长则通入氧气的玻管就被烧熔,并且由于通入氧气的尖嘴管的管口距离瓷管的管口(外端)太远,这样将火焰引入瓷管内燃烧,氧气流要相当大其火焰才能露出管口,由于火焰在瓷管内燃烧,这样很快将瓷管烧红,橡皮管燃烧起来,瓷管同时也被烧坏,另一方面氧气流不好控制,气流小时火焰不能露出管口,气流过大时又将火焰冲熄,再一方面由于这种装置在演示时还得临时加热,不能采用储气瓶,是不很方便的,鉴于这些缺点,我们仅提出以下改进意见。
1954 No. 4 ChemChina Bulletin published Comrade Zhu Yinfu self-made experience of blowing oxygen pipe, after our trial is not good enough, in the first few dozen seconds can get good results. When the time is longer, the glass tube into which oxygen is introduced is burned. Since the mouth of the spiked tube that leads to oxygen is too far away from the spout (outer end) of the porcelain tube, the flame is introduced into the porcelain tube for combustion and the oxygen flow To a considerable flame to reveal the nozzle, due to the flame burning in the ceramic tube, so soon porcelain burning red, rubber tube burning up, but also the ceramic tube is burned, on the other hand oxygen flow is not good control, airflow hours Flame can not be exposed nozzle, the air flow is too large and then blaze the flame again, on the other hand due to this device in the demonstration had to be temporary heating, can not use the gas cylinder, is not very convenient, in view of these shortcomings, we only put forward The following improvements.
