Silicone can be used as desiccant and can be reused. Silica gel is a porous substance with different particle sizes due to the mSiO2 and Nheo of silicate gels. With an open porous structure, it is a very good desiccant, adsorbent and Catalyst Carrier, which is much larger than the surface (the surface area of the unit mass) and can adsorb many substances. The adsorption function of silica gel is mainly physical adsorption, can be regenerated and reused. In alkali-metal silicate (such as sodium silicate) solution to add acid, so that the acidification, and then add a certain amount of electrolyte to stir, that is, the formation of silicate gel, or in a thicker sodium silicate solution with acid or ammonium salt can also be produced silicic gel. Will gel static for a few hours to make the aging, and then wash away with hot water soluble salts, drying in the 60 and in about 300 Shan activation, you can get silicone. The silicate gel is soaked with cobalt chloride solution and then dried and activated, which can change the silica gel. Use it as a desiccant, before the water is blue, after absorbing water to turn 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 steam, oil refining and catalyst preparation. Silicone can also be used to make mobile phone shells, with extremely high resistance to fall
