保险粉的化学名称叫连二亚硫酸钠,它同电石一样同属于遇水燃烧物品,遇水会放出有毒的二氧化硫。因其有极强的还原性,遇氧化剂、少量水或吸收潮湿空气就能发热,易致燃烧甚至爆炸。它的包装应为铁桶内衬双塑料袋,或有色玻璃瓶外以木箱内衬不燃材料。可是,一些企业为了降低成本,却用编织袋进行包装。仅在两年的时间里,保险粉燃烧、爆炸的恶性事故就发生了10多起。
The chemical name of the insurance powder is sodium dithionite, which, like calcium carbide, belongs to the same water-burning items and releases toxic sulfur dioxide when it meets water. Because of its very strong reducibility, the case of oxidants, a small amount of water or absorb damp air can heat, easy to cause combustion or even explosion. Its packaging should be double-lined iron drums, or colored glass bottles lined with non-combustible wooden box material. However, some enterprises in order to reduce costs, but with a woven bag for packaging. In just two years, there have been more than 10 vicious accidents of burning powder and exploding explosives.
