Calcium chloride, a salt composed of chlorine and calcium, has a chemical formula of CaCl2. Colorless cubic crystal, white or grayish white, granular, honeycomb block, spherical, irregular granular, powdery. It is slightly toxic, odorless and slightly bitter. It is a typical ionic halide and is a white solid at room temperature. It is extremely hygroscopic and is easily deliquescent when exposed to air. Soluble in water, while releasing a lot of heat, its aqueous solution is slightly alkaline. Soluble in alcohol acetone acetic acid. With the action of ammonia or ethanol, the CaCl28NH3 and CaCl24C2H5OH complexes are respectively 
classified into calcium chloride according to the use: industrial grade and food grade 
according to content: anhydrous calcium chloride 94%, liquid calcium (27%-40%) and two Water calcium chloride 74% (with two crystal water, content of 74%) 
anhydrous: granules, powder, flakes, waterless thorns (dehumidification bags, exported to the United States as a snow melting agent) 
Dihydrate: granules Shape, powder, flake, dihydrate ball (dehumidification box), 

Snow melting agent, using calcium chloride to melt heat and low freezing point as a road deicer and snow melting agent
Dehydrating agent, used as a dehydrating agent in the production of alcohols, esters, ethers and acrylic resins. 
Refrigerant, calcium chloride aqueous solution is an important refrigerant for refrigerators and ice making. 
Antifreeze agent can accelerate the hardening of concrete and increase the cold resistance of building mortar. It is an excellent building antifreeze. 
Early strength agent: early strength agent in construction industry, improving concrete strength, coagulant for living coatings 
Dust collector, used as antifogging agent for pavement and pavement dust collector and fabric fireproofing agent. 
Refining agent, used as a protective agent and refining agent for aluminum-magnesium metallurgy. 
Precipitant, a precipitant for the production of lake pigments. 
Coagulant: Inorganic chemical raw materials and sulfate removal agent for chemical industry, sodium alginate 
foods as a food additive calcium chloride is a widely used, general food calcium chloride for the food industry in the following situations: 
a beverage, as the electrolyte, enhancing the palatability 
pickled, calcium chloride It has a salty taste and can reduce the amount of salt in the 
cans. It can gelatinize and strengthen the consistency of the soup porridge 
, so that the soybeans can be emulsified and solidified. Improve the smoothness of tofu
