The main uses of anhydrous calcium chloride are as follows:
1. Used as a multi-purpose desiccant, such as drying of nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases. Used as a dehydrating agent in the production of alcohols, esters, ethers and resins. Calcium chloride aqueous solution is an important refrigerant for refrigerators and ice making, which can accelerate the hardening of concrete and increase the cold resistance of building mortar, and is an excellent building antifreeze. It is used as antifogging agent in port, road dust collector and fabric fire retardant. Used as protective agent and refining agent in aluminum-magnesium metallurgy. It is a precipitant for the production of lake pigments. Used for deinking of waste paper processing. It is the raw material for the production of calcium salts.
2. Chelating agent; curing agent; calcium fortifier; refrigerant for freezing; desiccant; anti-caking agent; antimicrobial agent; pickling agent; tissue improving agent.
3. Used as desiccant, road dust collector, antifogging agent, fabric fire retardant, food preservative and for the manufacture of calcium salts
4. Used as lubricant additive
5. Used as analytical reagent
6. It is mainly used for the treatment of exudative edema, intestinal and ureteral colic, magnesium poisoning, etc. caused by the decrease of blood calcium.
7. Used as calcium fortifier, curing agent, chelating agent and desiccant in the food industry.
8. Desiccant that can increase the permeability of bacterial cell walls Granular anhydrous calcium chloride is often used as a desiccant to fill the drying tube, and the macroalgae (or seaweed ash) dried with calcium chloride can be used for the production of soda ash and deicing Calcium chloride can lower the freezing point of water. Spreading calcium chloride hydrate on roads can prevent icing and de-icing and melting snow, but salt water from melting ice and snow can damage the soil and vegetation along the road and deteriorate the road concrete. .
