White Granular Industrial Grade Refined Salt NaCl Sodium Chloride
Industrial salt is one of the most basic raw materials in the chemical industry. Its main components are sodium chloride and sodium nitrite. It is used to produce chemical products such as hydrochloric acid, caustic soda, soda ash, hydrogen, chlorine, etc. Industrial salt can be divided into industrial granular salt and industrial refined salt according to whether it is processed or not. Industrial refined salt has a higher sodium chloride content and less impurities.

1. Application in the chemical industry
Salt is the mother of the chemical industry. The chemical industry is the basic industry of the national economy. Three acids (sulfuric acid, hydrochloric acid, and nitric acid) and two alkalis (soda ash and caustic soda) are the basic chemical industries, and hydrochloric acid, soda ash, and caustic soda are produced with salt as the main raw material. Every ton of soda ash or caustic soda produced consumes 1.2 to 1.4 tons of raw salt.
2. Application of salt in the metallurgical industry
It is used as a chlorination roasting agent and quenching agent in the metallurgical industry, and also as a desulfurization agent and clarifier for treating metal ores.
3. Application in the machinery industry
During casting, salt can be used as an excellent binder for non-ferrous metal and alloy casting medium sand. At high temperatures, salt softens the casting core, thereby preventing the occurrence of thermal cracks in the casting. Compared with organic adhesives, salt produces the least harmful gases at high temperatures. When heat treating steel mechanical parts or tools, the most commonly used heating equipment is a salt bath furnace.
4. Application in the dye industry
The common raw materials used in the dye industry, such as caustic soda, soda ash and chlorine, are directly produced from salt. Hydrochloric acid, sodium sulfide, hydrosulfite, etc. are chemical products made from salt through deep processing. In addition, a large amount of salt is directly consumed. Therefore, the dye industry is one of the industries that has a very close relationship with the salt industry, besides the chlor-alkali industry. Moreover, almost every step in the dye production process consumes a certain amount of salt.
5. Application in the building materials industry
Soda ash made from salt is the main raw material for producing glass. In addition, in order to eliminate bubbles in the glass melt, a certain amount of clarifier must be added when melting glass, and salt is also a component of the commonly used clarifier, and the amount of salt used is about 1% of the glass melt.
