Usage: It can be used as the activating agent in the production of activated carbon in inorganic industry, it can also be used as the raw material for the production of foaming fire-fighting fluid and for the production of zinc cyanide. In organic industry, it can be used as solvent of polyacrylonitrile, contact agent, dehydrating agent, condensating agent, deodorizer in organic synthesis. Special activating agent can be used as catalyst for the production of O-Vanillin, cyclamen aldehyde, cation exchange resin. In dyeing and printing industry, it can be used as mordant, mercerizing agent. In electroplating industry, it can be used as the zinc ion additive of ammonium salt. In pigment industry, as the raw material of white pigment. In metallurgical industry, used in the production of aluminium alloy and as rust remover in welding.
