UN3356 化学氧气发生器

化学氧气发生器是一种含有化 学品、当发生化学反应时产生 氧气的装置。化学氧气发生器 用于产生氧气，维持人员呼 吸。例如：飞机、潜艇、航天 飞机、防空洞和呼吸器。氧气 发生器所使用的氧化性盐如 锂、 钠、钾的氯酸盐和高氯酸 盐，在加热时可以放出氧气。 这些盐与燃料(通常为铁粉)混合 (化合)，形成含氯酸盐的烛状 物，通过持续反应产生氧气。 氧化反应产生热量，反应开始 时，热盐热分解放出氧气(在发 生器四周有热保护装置)，部分 氧气与燃料反应产生的热量使 热盐产生更多的氧气，等等。 也可以用撞击、摩擦、电加热 装置来引发反应。

Oxygen generators, chemical are devices containing chemicals which, upon activation, release oxygen as a product of chemical reaction. Chemical oxygen generators are used for the generation of oxygen for respiratory support, e.g. in aircraft, submarines, spacecraft, bomb shelters and breathing apparatus. Oxidizing salts such as chlorates and perchlorates of lithium, sodium and potassium, which are used in chemical oxygen generators, evolve oxygen when heated. These salts are mixed (compounded) with a fuel, usually iron powder, to form a chlorate candle, which produces oxygen by continuous reaction. The fuel is used to generate heat by oxidation. Once the reaction begins, oxygen is released from the hot salt by thermal decomposition (a thermal shield is used around the generator). A portion of the oxygen reacts with the fuel to produce more heat, which produces more oxygen, and so on. Initiation of the reaction can be achieved by a percussion device, friction device or electric wire.
