Silica Gel High Temp Rubber Seal 60 - 70 Harndess Non Toxic Electrical Insulation

Silica gel is also widely used in steam recovery, petroleum refining and catalyst preparation

Silica gel can be used as a desiccant and can be reused. Silica gel is a kind of porous material with different particle sizes, which is properly dehydrated from silicic acid gel msio2•nh2o. It has an open porous structure that is larger than the surface (surface area per unit mass). It can absorb many substances. It is a good desiccant, adsorbent and catalyst carrier. The adsorption of silica gel is mainly physical adsorption, renewable and reusable. In the alkali metal silicate (such as sodium silicate) solution to add acid, make it acidified, and then add a certain amount of electrolyte stirring, namely the formation of silicic acid gel; Alternatively, silicic acid gels can be made by adding acid or ammonium salts to a thicker solution of sodium silicate. Silicic acid gels were left to age for several hours, then the soluble salt was rinsed with hot water, dried at 60~70 ° C and activated at around 300 ° C to obtain silica gel. Whether silicic acid gels can be soaked in cobalt chloride solution and then dried and activated to obtain color-changing silica gel. When used as a desiccant, it can turn red before and after water absorption. Silica gel is also widely used in steam recovery, oil refining and catalyst preparation. Silica gel can also be used as a mobile phone case, high fall resistance.
