It is called silicone products processed with silicone as the main raw material.
Silicone is a kind of porous material with different particle size due to dehydration of silicic acid gel.
With an open porous structure, can adsorb many substances, is a good desiccant, adsorbent and catalyst carrier.
The adsorption of silicone is physical adsorption, can be recycled and used repeatedly. The alkali metal silicate (such as sodium silicate) solution with acid, the acid electrolyte, then adding a certain amount of mixing, which generates silicate gel; or in sodium silicate solution is strong in acid or ammonium salt can generate silicate gel silica gel. Standing a few hours to aging, and then wash with hot water soluble salts, at 60 to 70 degrees Celsius and drying at approximately 300 degrees Celsius when activated, can be soaked with silicone. The cobalt chloride solution after drying and activation, multicolor silicone.
