Anhydrous calcium chloride/ calcium chloride dihydrate |
 |
 |
 |
There are two types: Anhydrous calcium chloride (CaCI2) and Calcium chloride dihydrate (CaCl2·2H2O). Appearance is white or slight yellow solid, shapes are porous block, powder and particle.It can be used in drier, refrigerant, Antifreeze powder, fire retardant, food adsorbing antiseptic, dehydrant, and so on. It is widely used in food, electron, leather and petrochemicals.
Calcium chloride dihydrate is 74%, 77%, Anhydrous calcium chloride=95%.
Packing specifications: powdery calcium chloride dihydrate 25?; granular anhydrous calcium chloride 25?, 40?; granular (tablet) calcium chloride dihydrate 40?; powdery anhydrous calcium chloride 25?, 40?. |
Quality standard: HG/T2327-92 |
