High-temperature sleeve, also known as silicon rubber fiberglass casing, is made of high-purity alkali-free glass fiber woven into a tube, and then coated with organic silica gel on the outer wall of the tube and then vulcanized. After vulcanization, it can be used for a long time in the temperature range of -65°C-260°C and maintain its soft and elastic properties.
The synthesis of special high temperature resistant materials determines that the high temperature casing has many other similar materials that are difficult to replace: high temperature performance, thermal insulation performance, flame retardant performance, electrical insulation performance, chemical stability, weather resistance, cold resistance, water resistance , Oil resistance, ozone resistance, voltage resistance, arc resistance, corona resistance, etc., especially safety and environmental protection performance. It is the best substitute for asbestos and other hazardous products.
The surface of the high-quality fireproof shell is smooth, free of lumps, bubbles, cracks, scratches and impurities. The surface of the fireproof shell is poor, uneven, and there are impurities such as agglomerates and bubbles.
Secondly, after understanding the silicon coating, you can see the internal fiberglass system, high-quality fire-resistant shell, and the internal fiberglass system is clean without messy fiberglass. Glass fiber is mostly white, and a few are milky white and light yellow. Because the low-quality glass fiber system is loose and messy, the color of the low-quality refractory casing glass fiber is not pure, and there will be some impurities. High-quality fire-resistant enclosures have no obvious pungent odor, and inferior fire-resistant enclosures have pungent odors. Long-term inhalation is very harmful to humans.
