The special fire-resistant sheath for flame-retardant, heat-insulation and high-temperature resistant cables
is made of high-quality alkali-free glass fiber yarns, and then coated with organic high-temperature-resistant silicone resin for high-temperature treatment. As a professional sheath manufacturer, we will introduce these products to you.
Special fire-resistant sheath for flame retardant, heat-resistant and high-temperature cable has the following characteristics:
1. Safety and environmental protection, protecting the health of workers
Alkali-free glass fiber has strong tensile strength, will not crease and break, is resistant to sulfur, is smokeless, halogen-free, non-toxic, pure oxygen, non-combustible, and has good insulation properties. After being cured by organic silicone, it will further strengthen its safety and environmental protection performance and effectively protect Workers' health and reduce the incidence of occupational diseases. Unlike asbestos products, it is extremely harmful to humans and the environment.
2.Excellent high temperature resistance
The organic silicon structure on the surface of the fire-resistant heat-resistant cable
special fire-resistant cable sheath contains both "organic groups" and "inorganic structures". This special composition and molecular structure make it integrate the characteristics of organic and inorganic functions In one. Compared with other polymer materials, its outstanding feature is high temperature resistance. With silicon-oxygen (Si-O) bonds as the main chain structure, the bond energy of the C-C bond is 82.6 kcal / g molecule, and the bond energy of the Si-O bond is 121 kcal / g molecule in silicone, so Its thermal stability is high, and the chemical bonds of the molecules do not break or decompose at high temperatures (or radiation exposure). Silicone is not only resistant to high temperatures but also to low temperatures and can be used over a wide temperature range. Whether it is chemical or physical mechanical properties, the change with temperature is small.
3. Splash proof and multiple protection
In the smelting industry, the temperature of the medium in the electric furnace is extremely high, and it is easy to form high-temperature splashes (also in the electric welding industry). After cooling and solidifying, slag is formed on the pipe or cable, which will harden the rubber on the outer layer of the pipe or cable and become brittle化 rupture. Furthermore, unprotected equipment and cables are damaged. Multiple silicone-coated fire tubes can achieve multiple safety protections. The high temperature resistance can reach 1300 degrees Celsius, which can effectively block high-temperature molten materials such as molten iron, copper, and aluminum. Spray to prevent damage to surrounding cables and equipment.
4. Heat insulation, energy saving and radiation resistance, radiation resistance
In high-temperature workshops, many pipes, valves or equipment have very high internal temperatures. If they are not covered with protective materials, they can easily cause burns or heat loss. High temperature resistant casing has better thermal stability than other polymer materials, as well as resistance to radiation and heat insulation, preventing accidents, reducing energy consumption, and preventing the heat of the medium in the pipeline from being directly transferred to the surrounding environment, making the workshop The temperature is too high, saving cooling costs.
5, moisture-proof, oil-proof, weather-proof, anti-pollution, prolong the service life of equipment
Fire-resistant heat-resistant cable special fire-resistant sheath
has strong chemical stability. It does not react with oil, water, acid and alkali in silicone. It can be used for a long time without aging under 260 ℃. The service life can reach dozens of years, which can largely protect the pipelines, cables and equipment in these occasions and greatly extend their service life.
In summary, compared with other sheath products, silicone insulation sheath has many advantages, welcome everyone to consult and buy.
