Generally, after the silicone rubber products are molded, the surface of the products will absorb a layer of dust or fiber silk, which will affect the beauty of the products.
Therefore, the silicone rubber manufacturer has taken corresponding measures to deal with the problem that the silicone rubber products are easy to absorb dust, such as the use of anti-static rubber, anion separation, etc., but this is very troublesome for the majority of consumers. Therefore, the corresponding protective measures can only be taken after understanding their adsorption capacity.

First of all, our silicone rubber manufacturers will cover the surface of the products that cannot be removed in time with a layer of plastic after the production of silicone rubber products. If the products need to be stored for a longer time, they need to be packaged with film bags to prevent dust from adhering to the surface of silicone rubber products and effectively ensure the appearance quality of the products. For products that are easy to absorb dust on the surface of the product, our silicone rubber product manufacturers generally recommend customers to spray feel oil. The feel oil is an oily substance that can adsorb silicone rubber surface, increase the smoothness of the product surface, isolate the contact between the outside world and the product surface, and truly achieve the effect of preventing silicone rubber products from absorbing dust. Because silicone products are mainly based on physical adsorption, even if they are placed there, they will be adsorbed to the product surface with electrostatic reaction. Silicone resin, as an anode material, can be used as various chemical auxiliary materials, and has relatively strong adsorption reaction to other polar substances. In order to enhance the adsorption capacity of silicone rubber, the active structural unit of the adsorbent should be added.

If the silicone rubber is calcined to be completely dehydrated, the silica hydroxyl group of the silicone rubber will be completely destroyed, reducing or even having no adsorption capacity. If a large amount of water is added to the silicone rubber, its adsorption capacity will also be reduced, because too many hydrogen bonds are formed between the silicon hydroxyl group and water, thus reducing the proportion of reactivity.

What if the silicone protective sleeve and other products are accidentally contaminated with a large amount of dust? We can try the following methods to deal with it.

1. Slight dust can be wiped with a dust-free cloth, and the dust on the product surface can be removed;
2. Serious dirt and dust can be wiped with white electric oil, or directly soaked in white electric oil liquid and then wiped with clean dust-free cloth.
