Characteristics of silicone and silicone rubber raw materials and industry application market
Silica gel is a highly active adsorption material, which is an amorphous substance. Its chemical molecular formula is mSiO2? nH2O. Insoluble in water and any solvents, non-toxic and odorless, chemically stable, and does not react with any substances except strong bases and hydrofluoric acid. Various types of silica gel have different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many other similar materials that are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.

    Silicone raw materials can also be called mold silicone rubber, pad silicone, silicone rubber and so on.

    According to the size of its pore size, silica gel is divided into: large-pore silica gel, coarse-pore silica gel, B-type silica gel, and fine-pore silica gel. Due to the different pore structures, their adsorption properties are different. Coarse-pored silica gel has a higher adsorption capacity under high relative humidity, while fine-pored silica gel has a higher adsorption capacity than coarse-pored silica when the relative humidity is low, while type B silica gel has a pore structure between coarse and fine The adsorption capacity between silica gels is also between coarse and fine pores. Macroporous silica gel is generally used as a catalyst carrier, matting agent, toothpaste abrasive, etc. Therefore, different varieties should be selected according to different uses. After the silica gel absorbs moisture, it can be regenerated by methods such as exposure, baking, and air drying.

    Safety performance

    The main component of silica gel is silicon dioxide, which is chemically stable and non-toxic. Silica gel has a strong adsorption capacity and can have a drying effect on human skin. If the silicone gets into your eyes, rinse them with plenty of water and consult a doctor as soon as possible.

    The blue silica gel is toxic because it contains a small amount of cobalt chloride. Avoid contact with food and inhalation. If a poisoning event occurs, you should seek medical treatment immediately.

    As silica gel is more and more accepted by people, the application area of silica gel is getting better and better, and people's demand for silica gel raw materials is also growing. The market demand for silica gel raw materials in the future is very optimistic, because silica gel is a In weak cycle industries, the total demand is conceivable. In foreign countries, many industries now use silica gel. In China, the amount of silica gel in the entire Guangdong province accounts for more than 80% of the national total, and it may increase in the future!

    The advantages of silicone are gradually being discovered by people, replacing many other material applications in our daily life. The magic of silicone and silicone rubber materials is changing our lives. From the product classification, application characteristics and precautions of silicone rubber, silicone rubber raw materials, liquid silicone rubber raw materials, there will be their own differences. The application technology and main application uses of silicone rubber, liquid silicone rubber raw materials are well known. More to discover, research and explore.
