Can't be dried: ethanol and ammonia.
The main raw material of calcium chloride desiccant is calcium chloride, which is made of high-quality calcium carbonate and hydrochloric acid through reaction synthesis, filtration, evaporation concentration and drying.
Calcium chloride desiccant is a white porous block, granular or honeycomb solid, which tastes slightly bitter and odorless. The aqueous solution is colorless.
Mainly used as raw materials for producing other calcium salts in inorganic chemical industry; Used as calcium enhancer, curing agent, chelating agent, desiccant, etc. In the food industry.

Desiccant classification:
1, static drying
Quantitative adsorbent and quantitative solution reach equilibrium after a long period of full contact. For example, moisture-proof packaging: cameras and photosensitive materials, precision instruments, electrical appliances, food, medicines, shoes, clothes, leather, weapons, telecommunications equipment and so on. Air dehumidification: closets, cabinets, floors, musical instruments, etc.
2. Dynamic drying.
The adsorption column is filled with a certain weight of adsorbent, so that the solution with a certain concentration flows at a constant temperature at a constant speed, thereby determining the osmotic adsorption capacity and the equilibrium adsorption capacity. For example, air drying: air drying of instruments in warehouses, boathouses and pharmaceutical factories; Dehydration and purification of industrial gases: hydrogen, oxygen, nitrogen, chlorine, carbon dioxide, acetylene, ethylene, methane, ethane, propane, SO3, sulfur dioxide, natural gas and gas.
