Industrial grade calcium chloride is mainly used as desiccant, such as for the drying of nitrogen, oxygen, hydrogen, hydrogen chloride, carbon dioxide and other gases; it is used as dehydrating agent in the production of alcohol, ester, ether and acrylic resin; it is an important refrigerant for refrigerator and ice making; it can accelerate the hardening of concrete ground and increase the cold resistance of building mortar, and it is an excellent building antifreeze; It can be used as antifogging agent for port, dust collecting agent for road surface, waterproof agent for fabric, protective agent and refining agent for aluminum magnesium metallurgy, precipitant for lake color production, deinking agent for waste paper processing, and raw material for calcium salt production. He has many uses. You can go to the following section to learn more about it~
Industrial grade calcium chloride is colorless cubic crystal, white or grayish white, granular, honeycomb block, spherical, irregular granular, powder. It is slightly toxic, odorless and bitter. It has strong hygroscopicity and is easy to deliquescence when exposed to air. It is soluble in water and can release a lot of heat. The aqueous solution of calcium chloride is slightly acidic. Soluble in alcohol and acetic acid. The solution of industrial grade calcium chloride crystallizes at low temperature and precipitates hexahydrate. When heated to 30 ℃, it dissolves in its own crystal water. When heated to 200 ℃, it becomes dihydrate. When heated to 260 ℃, it becomes white porous anhydrous calcium chloride.
In the petroleum industry, industrial grade calcium chloride is used to increase the density of solid-free brine, and can also be added to the water phase of emulsion drilling fluid to inhibit the expansion of clay. Calcium chloride aqueous solution is an important refrigerant for refrigerator and ice making. It can accelerate the hardening of concrete and increase the cold resistance of building mortar. It is an excellent building antifreeze. When making ceramics, calcium chloride will be used as one of the material components, which will make clay particles suspended in the solution, so it is easier to use clay particles during grouting. Industrial calcium chloride is used in oil drilling, desiccant, deinking agent, dehydrating agent, refrigerant, antifreeze, early strength agent, dust collector, refining agent, precipitant, coagulant and coagulant. It is used in the production of pigment and printing and dyeing industry. It is also used in Deinking of waste paper. It is also the raw material for the production of other chemical products.
