Product Detail

Zinc chloride is one of the important products in the inorganic salt industry, and its application is very wide. Zinc chloride soluble in water, soluble in methanol, ethanol, glycerol, acetone, ether, insoluble in liquid ammonia. Strong deliquescence, can absorb moisture from the air and deliquescence. It has the properties of dissolving metal oxides and cellulose. Fused zinc chloride has good electrical conductivity. When hot, thick white smoke is formed. Zinc chloride is corrosive and toxic.

Application

1. It is used as dehydrating agent, shrinking agent in organic synthesis industry and catalyst for production of vanillin, rabbit aldehyde, anti-inflammatory analgesic drugs and cation exchange resin. It can be used as a solvent for polyacrylonitrile. Dyeing and weaving industry used as mordant, mercerizing agent, sizing agent. The textile industry is used as a raw material (cosolvent of cotton fiber) for the production of cotton sliver drums, shuttles and other materials, which can improve the adhesion of fiber. The dye industry is used as a stabilizer for the color salts of ice dyes and for the production of reactive dyes and cationic dyes. Used as oil purification agent and activator of activated carbon. Used for impregnating wood to make it preservative and flame retardant. Used as a flame retardant for cardboard and cloth products. For electroplating. Used as a flux for welding rods. The metallurgical industry is used for the production of aluminum alloys, the deacidification of light metals, and the treatment of oxide layers on metal surfaces. For the production of blueprints. Used as battery electrolyte. Used in the production of refractory foam fire extinguishing and zinc cyanide production raw materials. It is also used in the production of medicine and drugs.

2. water Chemicalbook treatment corrosion inhibitor. Zinc chloride is easily soluble in water, hydrolysis in water produces insoluble colloidal particles, making the compound corrosion inhibitor gelatinous turbidity and not clear and transparent, with the prolongation of time, these insoluble colloidal particles gradually aggregate and precipitate. In order to inhibit zinc salting out in the compound corrosion inhibitor, a small amount of acidic substances such as H2SO4, HCl, H3PO4 or glacial acetic acid are usually added.

3. high concentration for corrosion drugs, low concentration for astringent drugs, and can be disinfected and deodorized.

4. used as an analytical reagent, synthesis of anion exchange resin catalyst. And used as oil purification agent and organic synthesis dehydrating agent. It is also used in the manufacture of dry batteries.

5. used in batteries, tempered paper, wood preservatives, solder water (zinc chloride solution can dissolve metal oxides at high temperature), textile industry mordant, slurry and weight increase agent, oil purification agent and activated carbon activator, electroplating pretreatment agent, medicinal astringent, pesticide and catalyst, also used as astringent additive in cosmetics.
