Granular anhydrous calcium chloride is manufactured with the raw materials of high quality calcium carbonate and salt and through several processes of reaction synthesis, filtering, evaporation, concentration and drying. The exterior appears in the form of block and grain
Molecular formula: CaCl2
Molecular weight: 110.99
Usage: Granular anhydrous calcium chloride can be used as drying agent for drying nitrogen, oxygen, hydrogen, and sulfur dioxide gases. It also can be used as dehydrating agent in producing alcohol, ester, ether and propylene resin. Hydrotropic solution of calcium chloride is the important cryogen for refrigerator and ice making. It is also a good anti-freeze agent and agglomerating agent in construction for concrete hardening and cold hardiness of sand mortar. It can be antifogging agent in harbors, dust collection agent of road surface, fire-proofing agent of fabrics, protective agent and fining agent of aluminum and magnesium metallurgy, precipitant for lake pigments, raw materials for de-ink of waste paper and calcium salt. Hydrotropic solution of calcium chloride is the best flame retardant agent, which could be used in fields of preparing barium chloride, treating water in boilers, manufacturing calcium metal, fabric gluing, road treating, coal treating, leather making and pharmaceutics.
