High temperature casing

High temperature casing is made of high-quality E-glass fiber yarn woven into a tube, the high-temperature silicone coated with organic by high temperature. High temperature sleeve has a fire-retardant insulation, thermal insulation, anti-electric, soft, and other properties. Casing is mainly used in high temperature steel mills, smelters, glass, fire-fighting equipment, large transformers places and places of high temperature cable insulation. High temperature sleeve widely used in electricity, chemicals, metallurgy, shipbuilding, machinery manufacturing and other industries high-temperature region; metallurgical enterprises heating zone cables, fluid lines, feed quick couplings, rolling area roller mill cable, tubing; . sawing peripheral cables, tubing and fittings; coated steel cable car field product descriptions, etc. Fire performance test tube: high-temperature bending test 48 hours after the heating surface cracks or coating the surface of aging in a thermostatic oven of 260 ℃ No peeling produce low bending test was heated for 1 hour without cracking or surface coating surface without peeling phenomenon in a constant temperature of -70 ℃ in the oven. Film-coated test after test of continuous use thermostatic oven off or no surface dissolution phenomenon. Combustion test and no spontaneous combustion flame self-extinguishing (according to UL "; VW-1"; and CSA "; HFS"; test) Temperature Test (2000hr) 260 ℃ heating tests are normal without abnormal (30sec) 1200 ℃ heating test Glass fiber intact flame test burning rate of not less than 45s / 25mm --- SRG-1-7kv SRG-1-4kv, (motor insulation level can be higher than the H of C grade) normal minimum dielectric breakdown voltage 7.0 kv / min 4.0 kv / min normal average dielectric breakdown voltage 10.0 kv / min 7.0 kv / min compare the merits of high temperature casing products have the following features: security, environmental protection, protection of workers' health E-glass fiber itself has an exceptionally strong rally, will not wrinkle fracture resistance, curing, smoking halogen-free non-toxic, non-flammable oxygen, good insulation properties, and then cured silicone, strengthened its safety and environmental performance, effective protection of workers' health and reduce the incidence of occupational diseases. Unlike asbestos products such great harm to humans and the environment. Superior high temperature performance of high temperature silicone casing surface structure contains both "; organic group";, also contains "; inorganic structure"; that this particular composition and molecular structure so that it sets the characteristics of organic matter and inorganic matter functions in one. Compared with other polymer materials, the most prominent is the high temperature performance. Silicon - oxygen (Si-O) bond as the main chain structure, C-C bond energy of 82.6 kcal / mole, bond Si-O bond energy of 121 kcal / mol in the silicone, so Its high thermal stability at high temperatures (or radiation) molecular bond is not broken, do not break down. Silicone not only temperature but also low temperature, it can be used over a wide temperature range. Whether or chemical properties physical and mechanical properties, changes in temperature are very small. Splash, multiple layers of protection in the smelting industry, medium temperature of the heating furnace are extremely easy to form a high temperature sputtering (welding industry for that matter), after cooling and solidification of slag formed in the pipe or cable, will make the outer layer of the pipe or cable rubber hardening, embrittlement and eventually rupture. Further damage to unprotected devices and cables, multi-channel high temperature silica-coated casing, can achieve multiple security, the highest temperature up to 1300 degrees Celsius, can effectively block the molten iron, molten copper, aluminum and other high-temperature melt melting splashing, to prevent peripheral cable and equipment from being damaged. Insulation, energy-saving, high-temperature radiation-resistant plants, a lot of pipes, valves or equipment, the internal temperature is very high, if not covering the protective material, likely causing burns or heat loss, etc. Casing temperature better than other polymer materials, thermal stability and resistance to radiation and thermal insulation effect, prevent accidents, reduce energy consumption, but also prevents the heat medium in the pipe directly to the surrounding environment leaving the workshop temperature, saving cooling costs. Moisture, oil, anti-weathering, pollution prevention, extended equipment life high temperature sleeve has a strong chemical stability of the silicone oil, acid and other substances are not react within 260 ℃, long-term use and aging, service life up to the natural environment for decades, can maximize the protection of pipes, cables and equipment within these occasions, greatly extending its life. Ozone resistance, voltage, arc resistance, corona resistance because the surface coating silicone, its main chain -Si-O-, unparalleled key exists, it can not easily be decomposed by ultraviolet light and ozone. High temperature sleeve has good electrical insulation properties, dielectric loss, resistance, voltage, resistance, arc resistance, corona, a volume resistivity and surface resistivity of insulating materials etc. among the best in, and their electrical properties affected by temperature and frequency little effect. Therefore, they are a stable electrically insulating material, it is widely used in electronics, electrical industries. Flame, reduce the incidence and rate of spread of fire if the pipeline transportation of flammable or toxic media medium, can cause fire or casualties occur; cables are often due to local high temperature combustion occurs; the use of high temperature casing extremely high temperature glass fiber woven surface silica added with appropriate special materials such as flame retardants, it has excellent flame retardancy. Even if fire occurs, you can prevent the spread of fire, and still protect the internal piping intact for a long time, rescue important information to the data, the data provide sufficient time. The company has more than one hundred varieties of seven series, it is widely used in chemical, pharmaceutical, power, engineering machinery, metallurgy, shipbuilding, aviation, mining, vehicles and other industries. Sales network throughout the country over 30 provinces, municipalities and autonomous regions, and exported to Europe, Japan and South Korea. Middle East.
