The silicone mobile phone cases we apply are easy to get dirty and easy to absorb dust. Silicone mobile phone case manufacturers will also take corresponding measures when the products they make absorb a lot of dust, such as using anti-static rubber materials, negative ion separation, etc., but for It is very troublesome for the majority of consumers, so it can be properly prevented after understanding its adsorption force.
The product of the mobile phone case is made of silicone resin, which is mainly based on physical adsorption. Even if it is placed on the immobile cilia, the dust will adhere to the surface of the product due to electrostatic reaction. Because silicone resin is an anodic raw material, it can be used in various It is a chemical auxiliary material that has a strong adsorption reaction to other polar substances. In order to enhance the adsorption capacity of silica gel, the active structural unit of the adsorbent should be increased. If the silica gel is calcined to make it completely dehydrated, the silanol of the silica gel will be completely destroyed and the adsorption capacity will be reduced or even no.
If a large amount of water is added to the silica gel, its adsorption force will also decrease, because the silicon hydroxyl groups form too many hydrogen bonds with water, thereby reducing the activity ratio.
Secondly, silica gel products with relatively high hardness do not have the effect of absorbing dust and sundries, and products with low hardness are produced with electrostatic rubber materials, and there will be no phenomenon of sticking dust. For the adsorption problem of silicone products, the manufacturer of silicone rubber products can dry it first to remove a certain amount of static electricity, and then spray the hand oil to prevent dust from sticking. The main function of the hand oil is to improve the smoothness of the silicone surface and maintain the dustproof effect For consumers and friends, you can buy white electric oil to wipe it properly, and use a clean cloth to stick alcohol to remove the dust on the surface.
When the fineness is large enough, it will hardly affect the tensile strength, elongation and wear resistance of the product itself, but the increased wear resistance, fatigue resistance and tear strength need to add hand oil to the product performance requirements . It has little effect on the smoothness of the surface of the product, or increases the brightness.
