Characteristics and application of fire protection sleeve of fire protection sleeve
Safety and environmental protection to protect the health of the workersAlkali free glass fiber itself has very strong tension characteristics, will not wrinkle broken, anti sulfuration, smokeless halogen-free non-toxic, pure oxygen combustion, good insulation, followed by organic silica gel after curing, strengthens its safety and environmental protection, effective protection of workers health, reduce the incidence of occupation disease. Unlike asbestos products, they are extremely hazardous to the human body and the environment.
Superior resistance to high temperatureThe silicone structure on the surface of the fireproof casing contains both organic and inorganic structures. This particular composition and molecular structure make it characteristic of organic compounds and inorganic compounds. Compared with other polymer materials, the most prominent is its high temperature resistance. The silicon oxygen bond (SiO) as the main chain structure, C-C bond is 82 thousand and 600 kcal / mole, SiO bond card / 121 thousand in silicon molar, so its high thermal stability, high temperature (or radiation) molecular bond doesn't break, do not break down. Silicone is not only resistant to high temperature and low temperature resistance, can be used in a wide temperature range. Both chemical properties and physical and mechanical properties vary little with temperature.
Thermal insulation, energy saving, radiation resistanceIn the high-temperature workshop, many pipes, valves or equipment, the internal temperature is very high, if not covered with protective materials, easy to cause burns or heat loss. The fire tube has better thermal stability than other polymer materials and the role of radiation resistance and insulation to prevent accidents, reduce energy consumption, but also can prevent the medium in pipeline direct heat transfer to the surrounding environment and make the workshop temperature too high, cost saving cooling.
Anti splash, multiple protectionIn the smelting industry, medium temperature of the heating furnace is very high, easy to form high temperature spray (so welding industry), cooling and solidifying slag formed in a pipe or cable, the rubber pipe or cable outer hardening, and ultimately brittle rupture. Without further damage the equipment and cable protection, multi coated silica gel casing after fire, can achieve multiple safety protection, high temperature resistance can be as high as 1300 degrees Celsius, can effectively prevent the molten iron, molten copper, aluminum melting hot melt spray, prevent surrounding cable and equipment was damaged.
