Sodium hydroxide, also known as caustic soda, is an inorganic compound with the chemical formula NaOH
Sodium hydroxide has strong alkalinity and strong corrosiveness. It can be used as acid neutralizer, complex masking agent, precipitating agent, precipitation masking agent, color developer, saponification agent, peeling agent, detergent, etc., and has a wide range of uses.
Caustic soda, scientific name sodium hydroxide, should be stored in a cool, dry, well-ventilated warehouse. Should be away from fire, heat source. The temperature of the library does not exceed 35 °C, and the relative humidity does not exceed 80%.
The packaging must be sealed and protected from moisture. It should be stored separately from easy (combustible), acids, etc., and mixed storage should be avoided. Storage areas should be equipped with suitable materials to contain spilled materials.
There are two methods of industrial production of sodium hydroxide: causticization method and electrolysis method, and the caustic method is divided into soda ash causticization method and natural alkali causticization method according to different raw materials; The electrolysis method can be divided into diaphragm electrolysis method and ion exchange membrane method.
