How do you repair a damaged layflat hose
- Safety and environmental protection to protect workers’ health
Alkali – free glass fiber itself has special tensile strength, no wrinkle and break, vulcanization resistance, smokeless halogen-free non-toxic, pure oxygen non-combustion, good insulation properties, and after curing by organic silica gel, to strengthen its safety and environmental protection performance, effectively protect workers’ health, reduce the incidence of occupational diseases. Unlike asbestos products, which are extremely harmful to human health and the environment.
- Excellent high temperature resistance
The silicone structure on the surface of fire sleeve contains both organic group and inorganic structure. This special composition and molecular structure make it integrate the properties of organic matter and the functions of inorganic matter. Compared with other polymer materials, fire sleeve has high temperature resistance. The main chain structure is silicon oxygen (SI-O) bond, the bond energy of C-C bond is 82.6 kcal/g molecule, the bond energy of Si-O bond is 121 kcal/g molecule in organic silicon, so its thermal stability is high, chemical bonds of molecules under high temperature (or radiation irradiation) do not break, do not decompose. Silicone is resistant to both high and low temperatures and can be used over a wide range of temperatures. Both chemical properties and physical and mechanical properties change very little with temperature.
- Anti-splash, multiple protection
In the smelting industry, the medium temperature in the electric heating furnace is extremely high, and it is easy to form high temperature splashing (so is the electric welding industry). After cooling and solidification, slag is formed on the pipeline or cable, which will harden the rubber outer layer of the pipeline or cable, and finally brittle fracture. Then damage the unprotected equipment and cables. It can achieve multiple safety protection through the multi-channel silicone coated fire sleeve. The highest temperature resistance can be as high as 1300 degrees Celsius, can effectively prevent the molten iron, copper, aluminum and other high temperature molten spray, prevent damage to the surrounding cables and equipment.
- Heat insulation, energy saving and consumption reduction, radiation resistance
In high temperature workshops, many pipes, valves or equipment have very high internal temperatures, which if not coated with protective materials, can easily cause burns or heat loss.
Fireproof sleeve has better thermal stability than other polymer materials as well as radiation resistance and thermal insulation, preventing accidents, reducing energy consumption, and also preventing the heat from the medium in the pipe from directly transferring to the surrounding environment and causing the workshop temperature to be too high, thus saving the cooling cost.
- Moisture-proof, oil-proof, weather-proof, pollution-proof, prolonging the service life of the equipment
Fireproof sleeve has strong chemical stability, the organic silicon does not react to oil, water, acid and alkali and other substances, within 260℃, can be used for a long time without aging, the natural environment service life can be up to several decades, can maximize the protection of these occasions in the pipeline, cable and equipment, greatly extend its service life.
- Ozone resistance, voltage resistance, arc resistance and corona resistance
Because the surface is coated with silicone, its main chain is -Si-O-, and there is no double bond, so it is not easy to be decomposed by ULTRAVIOLET light and ozone. Fire sleeve has good electrical insulation performance. Its dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistance coefficient and surface resistance coefficient are among the best insulation materials, and their electrical performance is little affected by temperature and frequency. Therefore, they are a stable electrical insulation material, widely used in the electronics, electrical industry.
