 Calcium Chloride: Calcium Chloride Dihydrate, Calcium Chloride Anhydrous
Molecular Formula: CaCl2
Molecular Weight: 110.99
High-quality calcium carbonate and hydrochloric acid are adopted as raw materials for calcium chloride, which is manufactured and refined through processes of synthesis, evaporation and concentration with the annual manufacturing volume of 20000 tons for various content of calcium chloride (lumpy, honeycomb-like, particle-like)
Use: Calcium chloride anhydrous has strong moisture-absorbing action, being good dehydrant for the drying of organic solvent and various gases. Calcium chloride dihydrate is an important cryogen for refrigerator and ice making, and an important raw material for making molecular sieve, as well as demulsifier for sewage treatment.
Quality Index: Appearing white crystal ( lumpy,honeycomb-like)
