How silicone manufacturers handle the adsorption problem of silicone products
For users who frequently use silicone phone cases, it is found that silicone products often adsorb dust and fuzz, which can be very troublesome to clean. For silicone products, sticking to dust is a significant disadvantage. What are the measures to solve this problem.
The reasons for the adsorption problem of silicone products:
Silicone mainly has physical adsorption force. Even if it is placed without moving the surrounding cilia, dust will gradually adhere to the surface of the product with the reaction of static electricity. Organic silicon raw materials are anodic and can be used as various chemical auxiliary materials to have strong adsorption reactions to other polar substances. In order to enhance the adsorption force of silicone, the active structural units of the adsorbent should be added.
Therefore, if silica gel is calcined to completely dehydrate, the silicon hydroxyl groups of silica gel will be completely destroyed, reducing or even lacking adsorption capacity; If a large amount of water is added to silicone, its adsorption capacity will also decrease, because silicon hydroxyl groups form too many hydrogen bonds with water, thereby reducing its active type ratio.
Secondly, for products with high hardness, there is no effect of dust and debris adsorption, and for low hardness products produced with electrostatic adhesive, there will be no phenomenon of dust adhesion.
Solution to the adsorption problem of silicone products:
Baking to maintain product dryness and remove certain static electricity
When spraying tactile oil to prevent dust sticking, tactile oil is an oily substance whose main function is to increase the smoothness of the surface appearance of silicone and maintain the dust-proof effect.
