What is the reason why silica gel products are easy to absorb dust?

Debris dust makes many friends who love silicone products feel annoyed, love a mobile phone case because of dust and fluff and restless, for silicone products sticky dust is actually the biggest disadvantage of silicone material, regardless of any environment will appear in this situation, so many friends who love silicone products are also because of this - a little gradually no longer like, For silica gel products manufacturers to make silica gel products on the adsorption of dust is particularly large in the case will also take appropriate measures, such as the use of anti-static rubber raw materials, negative ions, but for the majority of consumers is very troublesome, so you can first understand its adsorption force can be properly prevented!

Silica gel is mainly physical adsorption force, even if it is placed where does not move the cilia around, dust will gradually stick to the surface of the product with the electrostatic reaction, because the organic silicon raw material is anodic, can do a variety of chemical auxiliary materials have a strong adsorption reaction on other polar substances, in order to enhance the adsorption force of silica gel, should increase the active structural unit of the adsorbent. Therefore, if the silica gel is calcined so that it is completely dehydrated, the silica hydroxyl group of the silica gel is completely destroyed and the adsorption capacity is reduced or even no; If a large amount of water is added to the silica gel, its adsorption force will also be reduced, because the silicon hydroxyl group forms too many hydrogen bonds with water to reduce its active type ratio.

Second for hardness higher product and without the influence of the adsorption of dust and debris, for low hardness products adopt electrostatic rubber production will not have a sticky dust, the phenomenon for Che gelatin adsorption problem for Che rubber products manufacturers can be baked to keep products belong to remove certain electrostatic drying, in spraying oil to prevent feel sticky dust, Feel oil is an oily substance. The main function is to increase the smoothness of the silicone surface appearance and maintain the dustproof effect. For consumer friends, you can buy white electric oil to wipe properly, and alcohol can also remove the dust on the appearance with a non-sitting cloth!
