WebWhat are desiccants? Desiccants are a type of sorbent that will remove moisture and water vapor from the surrounding environment, in many cases a MylarFoil bag, tin, drum, glass or another type of sealed enclosure.Desiccant media is a very hygroscopic, sometimes natural solid that is chemically inert which will trap water vapor molecules in … WebSep 18, 2013 · The water-absorption capability of desiccant is dependent on a variety of factors (e.g., desiccant type, humidity, temperature). For example, silica gel can absorb up to 40% of its weight in water. A 4’ x 6’ x 2’ electrical enclosure in a hot/humid environment would saturate 125 g of desiccant in about two air exchanges.
What is a Desiccant? - Definition from Corrosionpedia
A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant. Commonly encountered pre-packaged desiccants are solids that absorb water. Desiccants for specialized purposes may be in forms other than solid, and may … See more Although some desiccants are chemically inert, others are extremely reactive and require specialized handling techniques. The most common desiccant is silica gel, an otherwise inert, nontoxic, water-insoluble white … See more Desiccants are also used to remove water from solvents, typically required by chemical reactions that do not tolerate water, e.g., the Grignard reaction.
