Sodium chloride, chemical formula NaCl, colorless cubic crystal or fine crystalline powder, salty. The appearance is white crystals, and its source is mainly sea water. soluble in water. Impure sodium chloride is deliquescent in the air. The stability is relatively good, and its aqueous solution is neutral.
Wholesale industrial-grade large-particle sun-dried industrial salt Coarse salt, large-particle sea salt for hot compress water treatment
Industrial salt has a wide variety of uses, and the product categories are:
1. Sun-dried raw salt, including large-grain industrial salt and small white salt. Large-particle industrial salt is mainly used for hot compresses, boiler water treatment, and softened water treatment.
2. Refined salt is added with anti-caking agent, which can prevent agglomeration for a long time.
3. Haijing salt is mostly used for hot compress and bath salt.
4. Water softening salt, which is mostly used for softening water treatment.
5. Sea crystal can improve the survival rate of aquatic products.
use:
1. The commonly used raw materials in the dye industry, such as soda ash, are directly produced from salt, and almost every step in the dye production process consumes a certain amount of salt.
2. In the metallurgical industry, salt is used as a chlorinating roasting agent and quenching agent in the metallurgical industry
3. Soda ash made from salt in the building materials industry is the main raw material for glass production.
4. In casting in the machinery industry, salt can be used as an excellent binder for non-ferrous metals and alloy casting sand.
5. In the process of oil well drilling, in order to protect the integrity of the rock salt layer core, it is necessary to add salt as a stabilizer to the mud.
6. In soap making in light industry, salt is often added in order to maintain the proper viscosity of the solution.
Production Process:
The underground brine is introduced into the salt field, dried in the sun, 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. The brine obtained is evaporated to precipitate halide gypsum, centrifuged, and the sodium chloride obtained is dried to obtain salt. Rock salt and salt lake brine can also be used as raw materials and dried in the sun to obtain raw salt. When underground brine and well salt are used as raw materials, they are prepared by three-effect or four-effect evaporation and concentration, precipitation of crystals, and centrifugal separation.
