What are the main components of industrial salt?
In the chemical industry, a large amount of industrial salt is used as a raw material. The production of chemical products such as chlorine, bleaching powder, caustic soda, and soda ash is inseparable from industrial salt, and the main components of the work salt, chlorine and sodium, are used.
In addition to the main ingredient sodium chloride, industrial salt also contains a variety of impurity components, so it can not be called sodium chloride, but the convention is only one word "salt".
Industrial salt is mainly divided into two kinds: one is sodium nitrite; the other is NaCl.
The main ingredient of industrial salt is sodium nitrite.
Nitrite is a salt containing nitrite ions (NO2(-)). Can be used to add color, seasoning, sterilization. Poisonous, chemically stable (except nitrous nitrite, etc.).
Nitrite is a common substance that is widely used as a color former and preservative in the food processing industry.
