Materials

Silica gel is a porous substance that is mSiO2 by the silica gel and nH2O appropriately dehydration. It is a good desiccant, adsorbent and catalyst carrier to have open porous structure, which can absorb many substances than surface (the surface area of unit quality). The adsorption of silica gel is mainly physical adsorption, can be recycled and reused. In alkali-metal silicate (such as sodium silicate) solution to acid, to make it acidification, and then add a certain amount of electrolyte to stir, that is, the formation of silicate gel; Silica gel static for several hours to aging, and then use hot water to wash the soluble salts, under the Kamaboko drying and at about 300 ℃ activation, can be silicone.

The silica gel is soaked and activated after soaking with cobalt chloride solution and can be discolored. Use it as a desiccant, suction before the water is blue, water after absorbing red, from the color changes can see the degree of water absorption, and whether the need for regeneration treatment. Silica gel is also widely used in the recovery of vapor, oil refining and catalyst preparation.
