Processing works made of silica gel as the main raw material are called silica gel products. Silica gel is a porous material having a different particle size which is suitably dehydrated from a silicic acid gel. It has an open porous structure and can adsorb many substances. It is a good desiccant, adsorbent and catalyst carrier. The adsorption of silica gel is mainly physical adsorption, which can be regenerated and reused. Adding acid to an alkali metal silicate (such as sodium silicate) solution, acidifying it, adding a certain amount of electrolyte to stir, to form a silicic acid gel; or adding acid or a thicker sodium silicate solution Ammonium salts can also form silicic acid gels. The silicic acid gel is allowed to stand for several hours to be aged, and then the soluble salt is washed away with hot water, dried at 60 to 70 ° C and activated at about 300 ° C to obtain a silica gel. The silicate gel is immersed in a cobalt chloride solution, then dried and activated to obtain a color-changing silica gel.

Silicone is a very stable material, which is much better than a PVC material with similar touch, such as high temperature resistance, chemical properties, and aging resistance. Silicone sleeves generally do not have a bad phenomenon, which is discarded when the user is tired.
