anti caking agent

Superiority:

Anticaking agent (desiccant) also known as adsorption agent, is used in moisture-proof, mould proof, drying effect, by way of adsorption and reaction products for different chemical and physical adsorption desiccant adsorption dryer.Physical adsorption of desiccant silica gel and alumina gel, molecular sieve, activated carbon, bone charcoal, charcoal, mineral desiccant, or activated clay, the dry principle is to ship by physical adsorption of water molecules in the own structure.Desiccant [1] is a clearing agent absorbs moisture from the atmosphere, its principle is to ship by physical adsorption of water molecules in the own structure or chemically absorbing water molecules and change its chemical structure, become another kind of material
