The application of industrial salt in the chemical industry is very common, and the chemical industry is a basic industry in the national economy. Common uses of industrial salt are described as follows:
1. Chemical industry
Industrial salt is the mother of chemical industry, it is an important raw material of hydrochloric acid, caustic soda, chlorine gas, ammonium chloride, soda ash and so on.
2. Building materials industry
1, the main raw material for the production of glass alkali is made of industrial salt.
2. The glazes on coarse pottery, ceramic tiles and jars also need industrial salt.
3, in the melting of glass to add to eliminate the bubble in the glass liquid clarifying agent, is also made of industrial salt and other raw materials.
3 .The petroleum industry
1, some oil-soluble organic acid barium salt can be used as a gasoline combustion accelerator to promote the complete combustion of gasoline.
2, when petroleum refining, industrial salt can be used as a dehydrating agent to remove water mist in gasoline.
3, salt chemical product barium sulfate can make drilling mud weight and as a regulator.
4, boron nitride obtained from boron as raw material, its hardness is equal to diamond, can be used as a superhard material for the production of oil drilling drill bits.
5, magnesium oxide, magnesium hydroxide and magnesium carbonate can be used as ash modifier added to fuel oil to prevent high-temperature corrosion of vanadium combination.
6, in the refining process of kerosene, salt is used as a filter layer to remove the mixture.
7, During the drilling of oil Wells, industrial salt can be added to the mud as a stabilizer to protect the integrity of the rock salt core.
4. Machinery industry
1. At high temperatures, industrial salt makes the core of the casting soft, thereby preventing the generation of hot cracks in the casting.
2, industrial salt can be used as an excellent adhesive for non-ferrous metal and alloy casting sand.
3, ferrous metal and copper, copper alloy before electroplating strong pickling, need industrial salt.
4, steel mechanical parts or tools in the heat treatment, the commonly used heating equipment is salt bath furnace.
5. Metallurgical industry
1, industrial salt can also be used as a desulfurizer and clarifier for the treatment of metal ores.
2, industrial salt in the metallurgical industry can be used as a chlorination roasting agent and quenching agent.
3, in the pickling of strip steel and stainless steel, aluminum smelting, electrolytic and other AIDS to use industrial salt.
4, in smelting refractory materials, etc., need industrial salt.
5, steel products and steel rolled products immersed in salt solution, can make its surface hardening and remove the oxide film.
6. Dye industry
Not only the commonly used raw materials in the dye industry (such as caustic soda, soda ash and chlorine, etc.) are directly produced by industrial salt, but also hydrochloric acid and other chemical products obtained by deep processing of industrial salt. In addition, almost every step in the dye production process consumes a certain amount of salt. In addition, industrial salt is also widely used in water treatment, snow melting agent, refrigeration and refrigeration.
