We all know that there are two kinds of skins: silica gel and fluorine gel. What are the differences between the two kinds of skins? What are their characteristics and what conditions are they suitable for? Today, Hongsheng takes you to know about these two different kinds of skins. If you are interested, go ahead and have a look at them Silica gel skin is generally used in the air duct fabric compensator with low temperature resistance. When the insulation layer is added, it will be used at < 600 C. Fluorine rubber skin can be used in extreme environments, and its temperature resistance is less than 1200 C. Silicone rubber skin is made of glass fiber as base cloth, coated or calendered. It is made of high temperature resistant, anticorrosive and high strength glass fiber cloth, calendered or impregnated by silicone rubber. It is a new composite material with high performance and multi-purpose. From the coating surface, there are two kinds of silicone rubber cloth: single-sided silicone rubber cloth and double-sided silicone rubber cloth. The application characteristics of the two kinds of silicone rubber cloth are basically similar. The single-sided silicone rubber cloth is mainly used in some special cases without double-sided silicone rubber to save related costs, such as making shoes, only one-sided chemical corrosion resistance is needed when coating. Application Characteristics of Skin Silicone Rubber Cloth: 1. Used between low-temperature-70 ~high-temperature 230. 2. Ozone, oxygen, light and climate ageing resistance, good weather resistance in field use, life span of up to 10 years. 3. High insulation performance, dielectric constant 3-3.2, breakdown voltage 20-50 kv/mm. 4. Good flexibility, surface friction and elasticity. 5. Good chemical corrosion resistance. Application characteristics of skin tetrafluoro adhesive: 1. The medium temperature in the flue duct can reach 1000 C. 2. The long-term working temperature of outer skin is less than 250 C, and the short-term working temperature can reach 350 C. After installation, the outer temperature of outer skin is less than 50 C (with thermal insulation filler). 3. Skin bears positive pressure less than 40 000 PA. 4. Absorbable three-dimensional displacement. 5. Making high corrosion-resistant, wear-resistant, desulfurization and corrosion-resistant expansion joints. 6. Expansion joints for special import and export of gas turbines. 7. Non-metallic expansion joint rectangular non-metallic bellows compensator for bituminous air and pulverized coal pipeline.
