USES
1, the application in the chemical industry 
Salt is the mother of the chemical industry. The chemical industry is the basic industry of the national economy. Triacids (sulfuric acid, hydrochloric acid, nitric acid), two bases (soda ash, caustic soda) are the basic chemical industries, and hydrochloric acid, soda ash and caustic soda are produced from salt as the main raw material, and consume 1.2 per ton of soda ash or caustic soda. ~1.4 tons of raw salt, used in the production of more than 80 kinds of basic chemical products such as sodium alkali, chlorine and chlorine derivatives, accounting for more than 60% of the world's total salt consumption. In industrialized countries, chemical salt It generally accounts for more than 90% of the total salt consumption. Therefore, it can be said that the overall development of the national economy depends on the developed chemical industry, and the developed chemical industry depends on the developed salt industry. 
2. Application in the 
dye industry The raw materials commonly used in the dye industry, such as caustic soda, soda ash and chlorine, are directly produced from salt. Hydrochloric acid, sodium sulfide, insurance powder, etc. are chemical products obtained by deep processing of salt; in addition, directly It consumes a lot of salt. Therefore, the dye industry is one of the industries closely related to the salt industry except for the chlor-alkali industry. Moreover, a certain amount of salt is consumed in almost every step of the dye production process. 
3. Application 
in the metallurgical industry Salt is used as a chlorination roasting agent and quenching agent in the metallurgical industry, and also as a desulfurizing agent and clarifying agent for treating metal ore. The steel product and the steel rolled product are immersed in a salt solution to harden the surface and remove the oxide film. Stripping chemical products are required for pickling of strip steel and stainless steel, baking chemicals for aluminum smelting, electrolytic solution of sodium metal, etc., and salt chemical products, as well as refractory materials for smelting.
4. Application in the building materials industry 
Soda ash made from salt is the main raw material for the production of glass. In addition, in order to eliminate bubbles in the glass liquid when melting the glass, a certain amount of clarifying agent must be added, and the salt is also a component in a commonly used clarifying agent, and the amount of the salt is about 1% of the glass melt. 
General stoneware, ceramic tiles and cylinders require salt as a glaze. The salt consumption per cubic meter of pottery is 0.5 to 3 kg. 
In order to improve the performance of the enamel enamel, some additives are added before the coating. The salt is an enamel for the surface glaze to increase the strength of the slab and improve the resistance to scoring and abrasion after the enamel is made. . The maximum amount of salt per 100 kg of glaze is 0.3 kg. 
In addition, the salt residue (salt gypsum) and the calcium magnesium mud (salt mud) produced in the brine purification can be used as building wall panels, wall materials or fillers, and can also be used as cement filler. 
5. Application in the machinery industry 
When casting, salt can be used as an excellent binder for non-ferrous metals and alloy casting medium sand. At high temperatures, the salt promotes the casting core to soften, thus preventing the occurrence of hot cracks in the casting. Salts produce the least harmful gases at high temperatures compared to organic binders. 
Steel mechanical parts or tools When heat treatment, the most common heating equipment is a salt bath furnace. Compared with the heating of the box furnace, the salt bath furnace has the advantages of easy temperature control, uniform heating, fast heating speed, local heating, slender workpiece not easy to bend, and avoiding many advantages such as oxidation and decarburization. At the same time, it is used as a common catalyst in the carburizing chemical heat treatment, and quenching with brine during the heat treatment process can also obtain a more desirable effect. When ferrous metals and copper and copper alloys are strongly pickled before plating, salt is required. 
6. Application in the petroleum industry
In the oil well drilling process, in order to protect the integrity of the rock salt core, it is necessary to add salt as a stabilizer in the mud, and use the salt chemical product barium sulfate to make the drilling mud gain weight and act as a regulator. In the case of petroleum refining, in order to remove water mist in gasoline, salt is used as a dehydrating agent. In the kerosene refining process, the salt is used as a filter layer to remove the impurities. There are also many salt chemical products widely used in the petroleum industry. For example, some oil-soluble organic acid strontium salts can be used as accelerators for gasoline combustion to promote complete combustion of gasoline; magnesium oxide, magnesium hydroxide and magnesium carbonate can be used as ash upgrades. The agent is added to the fuel oil to prevent high temperature corrosion of vanadium compounding; boron nitride made of boron as raw material has the same hardness as diamond, and the stability is better than diamond in the high temperature of 1500-1600 ° C, which can be used as super Hard materials are used to produce drill bits for oil drilling. 
7. Application in light industry 
In the manufacture of soap, in order to maintain a suitable viscosity of the solution, salt is often added. Due to the action of sodium ions in the salt, the viscosity of the saponification liquid can be lowered, so that the saponification reaction proceeds normally. In order to achieve a sufficient concentration of sodium fatty acid in the solution, it is also necessary to add a solid salt or concentrated brine to carry out salting out and extract glycerin. In soaps and synthetic detergents, the salt chemical product sodium silicate is also used as a filler to increase the alkalinity, hardness and strength of the soap. 
The tanning industry requires a large amount of animal skin. During storage and transportation, in order to prevent or inhibit the erosion of microorganisms, it must be treated with anti-corrosion treatment to avoid reducing the quality of the skin. The most commonly used methods of preservation in the tanning industry are the salting method and the salt drying method. During the tanning process, the bare skin must be immersed in the pickling solution, and salt is also essential. The peeling of the hides in the tanning is carried out, and the salt chemical products such as sodium sulfide, sodium hydrosulfide and sodium thiosulfate are used for the leather tanning. 
In the paper industry, pulp, bleached pulp and fillers are used, and salt chemical products such as sodium sulfate, magnesium sulfate and sodium chlorate are used. 
A variety of salt chemical products are also widely used in the match, gunpowder, printing, film and photography industries. 
8. Application in national defense and cutting-edge technology 
Salt chemical products are also widely used in the electronics industry and the defense industry. 
Production Process
It is introduced into the salt field by underground brine (average 2.4% sodium chloride), dried by sunlight, concentrated and crystallized to obtain a crude product. The seawater can also be heated by steam, filtered by a sand filter, and concentrated by ion exchange membrane electrodialysis to obtain brine (containing sodium chloride 160-180 g/L), and the salt-halogen gypsum is precipitated by evaporation, and the obtained chlorine is separated by centrifugation. More than 95% of sodium (2% moisture) can be dried to prepare a table salt. It is also possible to use rock salt and salt lake brine as raw materials, and dry the sun to obtain raw salt. When using underground brine and well salt as raw materials, it is concentrated by three-effect or four-effect evaporation, crystals are precipitated, and centrifugal separation is obtained. 
Common methods 
1. Dissolve the crude salt in water to remove insoluble impurities, and then add refined preparations such as NaOH, Na2CO3 and CaCl2 to make soluble impurities such as SO42-, Ca2+, Mg2+, Fe3+ become precipitates, remove by filtration, and finally use pure hydrochloric acid. The pH was adjusted to 7, and the concentrated solution gave crystals of pure sodium chloride.
