Can dry: gas, widely used in oil seal, optical medical, health food and military products.
Can not dry: ethanol and ammonia.
Calcium chloride desiccant main raw material, calcium chloride is made of high-quality calcium carbonate and hydrochloric acid as raw material, and refined through the reaction and synthesis, filtration, evaporation and concentration, drying and other processes.
Calcium chloride desiccant is white porous block, granular or honeycomb solid, slightly bitter taste, odorless. The aqueous solution is colorless.
It is mainly used as the raw material for the production of other kinds of calcium salts in inorganic chemical industry; it is used as calcium fortifier, curing agent, chelating agent, desiccant and so on in food industry.

Desiccant Classification:
1, static drying
Quantitative adsorbent and quantitative solution after a long period of full contact to achieve equilibrium. For example, moisture-proof packaging: cameras and photographic materials, precision instruments, electrical appliances, food, drugs, shoes, clothing, leather, weapons, telecommunications equipment, etc.; air dehumidification: closets, cabinets, floors, musical instruments in the home.
2, dynamic drying.
A certain weight of adsorbent filled in the adsorption column, so that a certain concentration of solution at a constant temperature at a constant rate of flow through, so as to measure through the adsorption capacity and equilibrium adsorption capacity. For example, air drying: air drying for warehouses, ship warehouses, pharmaceutical factory instruments; industrial gas dehydration and refining: hydrogen, oxygen, nitrogen, chlorine, CO2, acetylene, ethylene, methane, ethane, propane, SO3, SO2, natural gas, coal gas.
