A desiccant is a hygroscopic substance that induces or sustains a state of dryness (desiccation) in its vicinity. Commonly encountered pre-packaged desiccants are solids that absorb water. Desiccants for specialized purposes may be in forms other than solid, and may work through other principles, such as chemical bonding of water molecules. They are commonly encountered in foods to retain crispness. Industrially, desiccants are widely used to control the level of water in gas streams. A Container desiccant is a product or material that can be absorbs moisture from the air, thus reducing the humidity in a controlled environment and thereby protecting goods from moisture damage Container Desiccant absorption characteristics Physical absorption Container desiccants absorb moisture physically by trapping the moisture inside its capillaries or its surface, yet the water molecules chemical properties remain unchanged, thus the moisture absorption process is reversible.Typical physical absorption desiccants are silica gel, molecular sieve, etc. Chemical absorption Container desiccants absorb moisture and convert the resultant mixture to another substance by changing its chemical properties a process that is irreversible.Typical chemical absorption desiccant: calcium chloride, magnesium sulfate, etc. The quantity of comparison of deciccant used The most common dessicants is use are silica gel and clay which only absorb from 10% to 27% of their dry weight, whereas Super Dry desiccant absorbs up to 300%. The absorption rate of Super Dry desiccant is 8 times up to 15 times than the common desiccants. For example, inside a hermetically seeled box of 1 cubic meter at 30C and 80% RH, there are 24 grams of moisture. To absorb all the moisture inside the box, about 100 grams of high quality common desiccant are required but only about 10 grams of Super Dry desiccant are required. Furthermore this makes Super Dry extreamly cost efficient verses other type of desicc
