molecular sieve desiccant

Common physical adsorption desiccant silica gel desiccant, clay desiccant, molecular sieve desiccant, mineral desiccant, fiber desiccant, montmorillonite desiccant.
molecular sieve desiccant
A desiccant material that can remove water in the wet material, often divided into two categories: a chemical agent such as calcium sulfate and calcium chloride, hydrate with water, dried by binding; physical desiccant such as silica gel and the active alumina and the like，molecular sieve grace  by physically adsorbed water and dried.
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, 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.
