Fine pore silica gel
Fine pore silica gel is colorless or yellowish transparent vitreous, its basic quality parameters are as follows: average pore spacing of 2.0-3.0nm, the specific surface 650-800 square meters /g, pore capacity 0.35-0.4ml/g, specific heat 0.92KJ/kg.℃, thermal conductivity 0.63KJ/m. hr . ℃.
Use: Suitable for drying, moisture-proof, rust-proof. It can prevent instruments, meters, weapons, ammunition, electrical equipment, medicines, food, textiles and other various packaged goods from moisture, and can also be used as a catalyst carrier and the dehydration of organic compounds refining. Because of its high bulk density and low humidity under the moisture-absorbing effect of the characteristics of the obvious, can be used as an air purifier to control air humidity. It is also widely used in shipping, because the goods are often deteriorated by moisture during transportation due to high humidity, and the product can be used to effectively remove moisture and prevent moisture, so that the quality of the goods can be guaranteed. Fine pore silica gel is also commonly used in the dehumidification between the two parallel sealing window panels, which can maintain the brightness of the two layers of glass.

Inorganic Silicone Uses
Silicone can be used as a desiccant and can be reused. Silica gel is a porous substance with different particle sizes made by proper dehydration of silicate gel mSiO2-nH2O. With an open porous structure, the specific surface (surface area per unit mass) is very large, can adsorb many substances, is a good desiccant, adsorbent and catalyst carrier. The adsorption effect of silica gel is mainly physical adsorption, which can be regenerated and used repeatedly. In alkali metal silicate (such as sodium silicate) solution with acid, acidification, and then add a certain amount of electrolyte for stirring, that is, the generation of silicate gel; or in the more concentrated sodium silicate solution with acid or ammonium salt can also generate silicate gel. Silicic acid gel will be left to age for a few hours, and then washed with hot water to remove soluble salts, dried at 60 ~ 70 ℃ and activated at about 300 ℃, you can get silica gel. Silicic acid gel will be soaked with cobalt chloride solution and then dried and activated, can get color-changing silica gel. When it is used as desiccant, it is blue before absorbing water, and becomes red after absorbing water, and the degree of water absorption can be seen from the change of color, as well as whether it needs to be regenerated. Silica gel is also widely used in the recovery of steam, oil refining and catalyst preparation. Silicone can also be used to make cell phone cases with extremely high drop resistance
