Calcium chloride is colorless cubic crystal, and the general commodity is white or white porous block or granular, honeycomb. Odorless and bitter. The relative density is 2.152, the melting point is 782 ° C, and the boiling point is above 1600 ° C. It is extremely hygroscopic, easily deliquescence in exposed air, easily soluble in water, and emits a lot of heat, and its aqueous solution is alkaline. Soluble in alcohol, acetone and acetic acid. With ammonia or ethanol, CaCl2 · 8NH3 and CaCl2 · 4C2H5OH complexes were formed. At room temperature, hexahydrate is usually crystallized from an aqueous solution. When it is gradually heated to 30 ℃, it will dissolve in its own crystal water, and it will gradually lose water when it is heated. It will become dihydrate to 200 ℃, and it will become white porous anhydrous calcium chloride when heated to 260 ℃.

Calcium chloride, as an important chemical product, has been widely used in industry, food processing industry and medicine. According to the amount of crystal water contained in calcium chloride, it is divided into calcium chloride dihydrate and anhydrous calcium chloride. The main products are powder, flake and granular. Divided by level: industrial grade calcium chloride and food grade calcium chloride.

Industrial grade calcium chloride application:
Industrial grade calcium chloride has the characteristics of heat generation and low freezing point when it meets water. And has a strong water absorption function, can also be used as a calcium chloride desiccant, such as for nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases drying. It is the best material for defogging the harbor, collecting dust on the pavement, and fireproofing the fabric. Calcium chloride aqueous solution is an important refrigeration medium for refrigerators and ice making. Dehydrator for the production of alcohols, esters, ethers and acrylic resins. It can also accelerate the hardening of concrete and increase the cold resistance of building mortar. It is an excellent antifreeze for buildings. Used as a protective agent and refining agent for aluminum-magnesium metallurgy. Adding calcium chloride additives to the calcined cement can reduce the calcination temperature of the cement clinker by about 40 ° C and improve the kiln production capacity. It is a precipitant for producing lake pigments. Deinking for waste paper processing. Is the raw material for the production of calcium salts. Calcium chloride solution is used as flocculant in sodium alginate industry and soy products industry.

Food grade calcium chloride application:
Food Grade Calcium Chloride is mainly used in food processing stabilizers, thickeners, moisture absorbents, and taste improvers. For example, it is used in the production of artificial shark fin, caramel, ice cream and dried fruit; the tenderization of rabbit meat, beef and other foods; the production of mulberry and orange fruit beverages, and the use of sucrose esters in bananas and other food preservation. In addition, it is also used to improve wheat flour complex protein and calcium fortifier in food. In medicine, calcium chloride is mainly used for drug synthesis. For example, the production of calcium L-aspartic acid requires calcium chloride as the raw material; it is used in the treatment of measles diseases in combination with sodium bromide;

2.How to Use Calcium Chloride Desiccant

STEP1:
Take the desiccant package out of the carton.
STEP2:
Open the plastic bag, make sure the desiccant is useful.
STEP3:
Take out suitable amount for use, put it into the package of your product and seal the package instantly.
STEP4:
The rest , reseal as soon as possible for next use.
