Silica Gel Introduction: chemical compound. It is a colloidal form of silica, and usually resembles coarse white sand. It may be prepared by partial dehydration of metasilicic acid, Because it has many tiny pores, it has great adsorptive power. Amorphous silica that resembles white sand and is used as a drying and dehumidifying agent, as a catalyst and catalyst carrier, as an anticaking agent in cosmetics, and in chromatography. Silica aerogel is fully dehydrated silica gel; it is very porous and is often used in insulation, e.g., for refrigerators..

Silica gel is a granular, porous form of silica made synthetically from sodium silicate. It is usually distributed in the form of beads, which are packaged in a semi-permeable packet. Its high porosity, around 800 m2/g, allows it to adsorb water readily, making it useful as a desiccant. It can reduce the relative humidity in a closed space to around 40%. Silica gel is non-toxic, non-flammable and chemically unreactive.

Silica Gel Products
Narrow/wide pore silica gel: lumpy/spherical silica gel. Silica gel for drying flowers: Silica gel desiccant; Silica sand with different colors; white, orange, blue etc. There are two kinds of narrow pore silica gel, the lump granule and bulb granule. It is mainly used in drying and purifying the air and kinds of industrial gases: preventing meter instrument, electronic products, equipment fabric, foodstuff, medicine, container and other packed material from moisture and rusting, as well as dehydrating, refinement of organic and so on.
Wide pore silica gel varies in size and shape. There are three types: lump granule, bulb granule and micro granule, it is mainly used as a carrier of catalyst. Also it performs the function of selective adsorption and purification in pharmacy, adsorbing the macro-globulin in the industrial ferment processing, adsorbing organic acid and high polymer insulating oils, dehydrating industrial gases, adsorbing the harmful elements in water as well as preventing moisture and rust.
Blue silica gel can absorb moisture just as the narrow pore silica gel. It changes color from blue to purple and then light pink while absorbing water. So it not only indicates the humidity of environment, but also tells whether the desiccant to be replaced. It can be used as desiccant independently or together with the narrow pore silica gel.
Silica sand is a revolutionary way to solve the problem of pet litter. It can absorb urine or liquid out of solid waste quickly and completely as well as the odor. So it can keep the air in your room fresh and dry.
We can supply kinds of packages in order to meet you demands.
