What are silicone products and what are their uses

　　Many friends are asking, what are silicone products, what are the uses of silicone products, and they are mainly used in those places. Today, I will explain the origin of silicone products again. The so-called silicone products are processed products with silicone as the main raw material. , generally referred to as silicone products. Silica gel is a porous substance with different particle sizes that is properly dehydrated from silicic acid gel. There are mainly fine-pored silica gel and coarse-pored silica gel, both of which have an open porous structure. It is precisely because of this porous structure that many substances can be adsorbed. It is a good desiccant, adsorbent and catalyst carrier. The adsorption of silica gel is mainly physical adsorption, which can be regenerated and used repeatedly.

　　Therefore, silica gel products are a relatively environmentally friendly product. Acid is added to an alkali metal silicate (such as sodium silicate) solution to acidify it, and then a certain amount of electrolyte is added for stirring to generate silicic acid gel; or Adding acid or ammonium salt to the concentrated sodium silicate solution can also generate silicic acid gel. Mainly, the silicic acid mixed gel is obtained by electrolysis under strong acid and strong alkali, and the silicic acid gel is left for several hours to age, and then the soluble salts are washed away with hot water, dried at 60-70 °C and heated at about Activated at 300°C to obtain silica gel. Silica gel is a transparent colloidal substance. The silicic acid gel is soaked in cobalt chloride solution and then dried and activated to obtain discolored silica gel. The production process of food-grade silica gel will be more detailed. Generally, food-grade silica gel is mainly used to produce some accessible food utensils.

　　Food-grade silica gel is non-toxic and tasteless, insoluble in water and any solvent, and is a highly active green product. Food-grade silica gel has inherent thermal stability (-40℃-230℃). It is suitable for a variety of different occasion. The products have good softness and meet different needs. In Japan or European and American countries, silicone kitchenware produced with food-grade silicone is the most common. In addition to silicone kitchenware, there are more silicone bibs, silicone pacifiers, silicone feeding bottles, etc. . These are a small category of silicone products.

　　Silicone products can also be used as electronic accessories, mainly making copiers, keyboards, electronic dictionaries, remote controls, toys, silicone buttons and other indispensable components. Remote control buttons are the most common type and have been used in every home. It can also be used to make durable forming gaskets, packaging materials for electronic parts, and maintenance materials for automotive electronic parts. It is used for the construction and repair of houses, the sealing of high-speed kilometers, the sealing of bridges and other sealing projects, and the wear-resistant and temperature-resistant characteristics of silica gel are applied. Used in medical device accessories, because of its colorless, odorless, and non-toxic properties, silica gel is widely used in the medical industry, mainly using medical-grade silica gel raw materials.
