ỨNG DỤNG
Calcium
chloride is the versatility of the desiccant, the aqueous solution is frozen
and ice important refrigerant. Can also speed up concrete hardening and
increase the ability of building cold mortar building antifreeze. The calcium
chloride also road dust agents, fabric of flameproofing agents, food
preservatives, and the manufacture of the calcium salt of raw materials. Is
also used for the production of barium chloride and certain dyes.
Medical
purposes: 1. Calcium chloride can be used to lower blood calcium tetany caused
colic, ureteric colic etc..
2
can be used for low calcium-induced urticaria, exudative edema, itching of the
skin.
3
for rescue magnesium poisoning.
4
for vitamin D deficiency rickets, osteomalacia, pregnant and lactating women
calcium supplement.
