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. The method generally, though not always, involves mixing the solvent with the solid desiccant. Studies … See more • Lavan, Z.; Jean-Baptiste Monnier & Worek, W. M. (1982).

WebFeb 4, 2024 · This makes them a poor choice for homes that are located within areas with high humidity levels (over 60% relative humidity). 2. Value. Desiccant dehumidifiers are designed to operate at a slower rate than electronic and refrigeration-based units. This means they remove very small amounts of moisture from the air per hour. WebApr 23, 2024 · A desiccant is a hygroscopic material that serves to maintain a state of dryness. It is the opposite of a humectant which serves to promote moisture retention. Desiccants eliminate humidity from the air and create and sustain a moisture-free environment. Moist, damp environments can result in damage to electronics, apparel, … can herpes appear anywhere
Desiccant - Wikipedia
WebDesiccators (also known as dehydrators or dehumidifiers) are packages to hold desiccant which function as self-contained moisture control … WebThe heat of mixing is a function of the equilibrium relative humidity of the desiccant: a lower equilibrium relative humidity produces a greater heat of mixing. The total heat that must be absorbed by the desiccant solution consists of the (1) heat of absorption, (2) sensible heat associated with reducing the dry-bulb temperature of the air ... WebMay 15, 2024 · Desiccants are sold in desiccant units. A desiccant unit is the measure of the quantity of desiccant which, at equilibrium with air at 23 ± 35.5°F (2°C), adsorbs the following quantities of water vapor: Min. 3.0 g at 20% relative humidity; Min. 6.0 g at 40% relative humidity can herpes appear years later
