We see a lot of silicone products in our daily life is a high density of a material, rarely see the phenomenon of silicone material seepage, so you can see a lot of desiccant made of silicone material in the market! But when it comes to adsorption in the solid silicone finished products, many silicone phone covers, silicone watch straps and other jewelry will appear sticky dust this phenomenon? So compared with other materials of jewelry silicone sticky dust is also its biggest drawback, but the adsorption of silicone many friends have always wanted to ask a question to understand, the same are silicone material why organic solid silicone products will appear to be dusty, and the general piece of silicone products will appear to stick to the dust of this phenomenon? What is there in this knowledge that deserves our attention?

  Adsorption is the main reason for silica gel dust, even if the use in good silica gel raw materials such as anti-static adhesive will appear natural physical adsorption, even if it is placed there without moving it will appear to adsorb the surrounding dust fibers, so silicone can be called physical adsorption silicone raw materials belong to the anodic, can do a variety of chemical auxiliary materials to other polar substances have a strong adsorption reaction, in order to enhance the adsorption of silica gel should increase the lively structural unit of the adsorbent. Therefore, if the silica gel is calcined to make it completely dehydrated, the silica gel's silicon hydroxyl group is completely destroyed and reduces or even has no adsorption capacity; if a large amount of water is added to the silica gel, its adsorption power will also be reduced because the silicon hydroxyl group forms too many hydrogen bonds with water thus reducing its active type ratio.
