A desiccant to absorb moisture from the atmosphere

A desiccant to absorb moisture from the atmosphere, in addition to a liquid, its drying principle is physically adsorbed water molecules in the structure itself, or the absorption of water molecules through chemical means, and changes its chemical structure, into another natural gas separation substances. Common desiccants are lime desiccant chemisorption, magnesium chloride, calcium chloride, phosphorous pentoxide, or soda lime, silicic acid, which are chemically absorb water molecules natural gas dehydration and change its chemical structure into another material.

Moisture control is the product yield is closely related to food, in the appropriate temperature and humidity, food, bacteria and mold will be breeding at an alarming rate, molecular sieve natural gas dehydration  so that food spoilage, resulting in moisture and color changed. Electronic products due to high humidity will cause the metal oxide, adversely. The desiccant is used in order to avoid the occurrence of excess water caused by defective products.
