    Product description
    Basic Information
    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. Easily soluble in water and glycerin, slightly soluble in ethanol (alcohol), liquid ammonia; insoluble in concentrated hydrochloric acid. Impure sodium chloride is deliquescent in the air. The stability is relatively good, and its aqueous solution is neutral. In the industry, the method of electrolysis of saturated sodium chloride solution is generally used to produce hydrogen, chlorine, caustic soda (sodium hydroxide) and other chemical products (generally called chlor-alkali industry). It can also be used for ore Smelting (electrolysis of molten sodium chloride crystals to produce active metallic sodium), medically used to prepare physiological saline, and daily life can be used as seasoning.
    Product Category
    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.
    The main purpose.
    The main purpose
    1. Application in the dye industry
    Raw materials commonly used 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. Application in metallurgical industry
    Salt is used as a chlorination roasting agent and quenching agent in the metallurgical industry, as well as a desulfurizing agent and clarifying agent for treating metal ores. Steel products and steel rolled products are immersed in a salt solution to harden the surface and remove the oxide film.
    3. Application in the building materials industry
    Soda ash made from salt is the main raw material for glass production. In addition, in order to eliminate bubbles in the molten glass when melting glass, a certain amount of clarifying agent needs to be added, and salt is also an ingredient in commonly used clarifying agents.
    4. Application in machinery industry
    During casting, salt can be used as an excellent binder for non-ferrous metals and alloy casting sand. At high temperatures, salt promotes the softening of the casting core, thereby preventing the occurrence of hot cracks in the casting.
    5. Application in the petroleum industry
    In the process of oil well drilling, in order to protect the integrity of the rock salt formation core, it is necessary to add salt as a stabilizer to the mud.
    6. Application in light industry
    In soap making, in order to maintain a suitable viscosity of the solution, salt is often added. It can increase the alkalinity, hardness and strength of soap. The tanning industry requires a large amount of leather. In the storage and transportation process of raw leather, in order to prevent or inhibit the corrosion of microorganisms, it needs to undergo anti-corrosion treatment to avoid reducing the quality of the leather. The anti-corrosion method commonly used in the leather industry is the salt-drying method.
    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.
