What Causes The Ashing Of Silicone Products?

            As the saying goes, if there are advantages, there can be no disadvantages. Any product cannot be foolproof. Basically, it will be purely flawed. In daily necessities, silicone materials occupy a part of our lives. Dust is a common product in silicone products. One of the drawbacks is that even if the products manufactured by the silicone products manufacturers have basically produced ash, this is a common problem in the entire industry, and it is also one of the disadvantages of many products. The main reason is due to the unique nature of the material. What are the main reasons that affect its adsorption of dust?

          Adsorption is the inherent characteristic of silicone materials. It can be used in the silicone industry for anti-mold, desiccant, and moisture absorption. The property of highly active adsorption material is the essence of silica, and it will automatically adsorb in the surrounding environment. The main reason for the fine dust is that the physical material in silicon dioxide is anodized, except that silica gel daily products are considered as many auxiliary materials and compound materials in inorganic silicon, but the cross-linking agent is different from it. Function, if the silanol group is completely destroyed and has no adsorption capacity, but different silica products are also related to other external factors, such as the following!

         The reason why the hardness of the material affects the adsorption of dust is mainly due to the different crosslinking agents added to it, which results in different adsorption strength effects. Silicone products with low hardness are more prone to staining. Due to the low hardness of the product, the main component of its material The more the cost of the silane coupling agent, the greater the adsorption strength caused by it, and products with higher hardness usually also have this problem, but the adsorption strength is not as large as that of low-hardness silica gel products!

        Among materials, silicone oil also affects the degree of adsorption. The more silicone oil components in the material during the refining process, the greater the viscosity of the surface, and the greater the degree of ashing of the product. This phenomenon is not mainly a matter of adsorption, but It is the surface silicone oil that makes the product more sticky, so it will naturally cause dust adsorption.


        The second problem is the mold problem. Different mold surfaces of silicone rubber products manufacturers have different effects on dust absorption. Because the surface of the mold is divided into a matte surface and a polished mirror surface, the matte mold is usually divided into a coarse matte surface and a fine matte surface. Different mists have different dusting effects on the surface of the product, and the most sticky is the polished and shiny surface. The surface does not have any gaps and sand holes, and the unique adsorption force of silica gel naturally causes dusting problems.

       The main reason for the problem of dusting is the nature of the material and the control problems of the silicone processing manufacturers. However, after the grinding of the process and the technological progress, the dusting of the silicone products has been eliminated by a variety of methods. At present, the current silicone products basically perform surface treatment on the dust. Such as fuel injection, electrostatic rubber, surface coating and so on!
