anti caking agent

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

Anticaking agent is a kind of highly active adsorption material, main composition is sio2, is a highly active adsorption material.Usually is to use sodium silicate and reaction, and the aging, acid soak and a series of post-processing process and system.Silica gel is amorphous material, its shape transparent not gauge side sphere, its chemical formula is mSiO2. NH2O.Desiccant is most suited to the moisture absorption of the environment for the room temperature (20 ~ 32 ℃), high temperature (60 ~ 90 ℃), it can reduce the environmental relative humidity around 40%, so the desiccant application scope is very broad.
