氯氣是製造多種化學藥品的主要原料,使用量非常大,它裝在特製的耐壓的鋼筒裏,筒口裝着一個黄銅的高壓開關,但並不是每筒氯氣的開關都可以順利的打開,因為它內部的各處小口極易因生成氯化物而發生銹蝕现象,甚至將各處小口堵塞,不是昇降閥桿擰不開,就是擰開後氯氣出不來。由於計划供應的關係,無法退回到產氣的單位中去掉換,因而在使用上造成極大的困難,僅1952年底的時候就有打不開的
Chlorine is the main raw material for manufacturing many kinds of chemicals. It is used in a very large amount. It is installed in a special pressure-resistant steel cylinder with a brass high pressure switch. However, not every cylinder of chlorine gas can be switched on smoothly, Because it is easy to corrosion inside the small mouth due to the formation of chloride, or even a small mouth around the plug, not lift the stem unscrew, that is, unscrew the chlorine out. Owing to the planned supply, it was impossible to return to the units producing gas for exchange. As a result, great difficulties were encountered in its use. It was not open until the end of 1952
