Is the silica gel desiccant of transparent in food poisonous?

Date of issue:2019-12-26 15:44
Transparent desiccant is called silica desiccant or glass desiccant, dry silica desiccant easy to absorb water. This desiccant is non-toxic and environmentally friendly. Life more common three kinds of food desiccant: transparent particles of silica gel, lime, mineral desiccant. Silica gel desiccant is a kind of environmental protection non-toxic moisture-proof products, product quality fully meet ROHS and REACH and other environmental requirements, it does not contain harmful substances, such as DMF (dimethyl fumarate).
Silica gel desiccant
is a highly active adsorbent material. After some treatment, silicic acid is an amorphous substance, the chemical formula is mSiO2, nH2O, no water or any solvent, non-toxic, tasteless. Silica gel desiccant chemical properties are stable, it will not react with strong base, hydrofluoric acid, any other substances. Because of their different manufacturing methods, various types of silica have different microporous structures. The chemical and physical structure of silica gel determines that it has many properties that are difficult to replace other similar materials: strong adsorption performance, good thermal stability, stable chemical properties and other safety properties. 
Silica gel desiccant is a physical adsorption desiccant. Silica gel absorbs water from the air through physical adsorption and does not react with water. There are many types of desiccant, divided into physical adsorption and chemical adsorption. Chemical adsorption of calcium oxide, calcium chloride or phosphorus pentoxide, silicate. Physical adsorption: silica gel, montmorillonite, minerals, etc.
