Beijing guweihao high temperature resistant casing is mainly used in metal metallurgy, high-speed railway coal coking, aerospace, military industry, nuclear power, new energy, construction, petrochemical, environmental protection and other high-tech fields as well as other special fields.
The performance of high temperature resistant casing is as follows:
1. Safety and environmental protection to protect workers’ health
Alkali free glass fiber itself has the properties of strong tensile force, no wrinkling and breaking, sulfur resistance, smokeless, halogen-free, non-toxic, pure oxygen incombustible, and good insulation. After cured by organic silica gel, its safety and environmental protection performance will be strengthened, the health of workers will be effectively protected, and the incidence of occupational diseases will be reduced. Unlike asbestos products, it is very harmful to human body and environment.
2. Excellent high temperature resistance
The organic structure on the surface of high temperature resistant fireproof casing contains both “organic group” and “inorganic structure”. This special composition and molecular structure make it integrate the characteristics of organic matter and the functions of inorganic matter. Compared with other polymer materials, its most outstanding performance is high temperature resistance. Silicon oxygen (Si-O) bond is the main structure. The bond energy of C-C bond is 82.6 kcal / mole. The bond energy of Si-O bond in silicone is 121 kcal / mole. Therefore, it has high thermal stability, and the chemical bond of molecule does not break or decompose at high temperature (or radiation). Silicone is not only resistant to high temperature, but also to low temperature. It can be used in a wide temperature range. Both the chemical properties and the physical and mechanical properties change little with the temperature.
3. Splash proof and multiple protection
In the metallurgical industry, the medium temperature in the electric furnace is very high, which is easy to form high-temperature splashing (the same is true in the welding industry). After cooling and solidification, slag is formed on the pipeline or cable, which will harden the rubber on the outer layer of the pipeline or cable, and eventually embrittle. Then damage the unprotected equipment and cables. The high temperature resistant cable protective sleeve coated with multiple silica gel can realize multiple safety protection, up to 1300 ℃, which can effectively prevent the splashing of molten iron, molten copper, molten aluminum and other high-temperature molten materials, and prevent the surrounding cables and equipment from being damaged.
4. Heat insulation, energy saving and radiation resistance
In high temperature workshop, many pipes, valves or equipment have very high internal temperature. If they are not covered with protective materials, it is easy to cause personnel burns or heat loss. High temperature resistant fireproof sleeve has better thermal stability, radiation resistance and thermal insulation than other polymer materials. It can prevent accidents, reduce energy consumption, and prevent the heat of the medium in the pipeline from being directly transferred to the surrounding environment while the temperature of the workshop is too high, thus saving the cooling cost.
5. Prevent moisture, oil, climate aging, pollution and increase the number of equipment use
Beijing guweihao high temperature resistant fireproof sleeve has strong chemical stability. Silicone can not react to oil, water, acid and alkali. It can be used for a long time and does not age under 260 ℃. Its service life in natural environment can reach several decades. It can maximally protect the pipelines, cables and equipment in these occasions and greatly prolong the service life.
6. Ozone resistance, voltage resistance, arc resistance and corona resistance
Because the surface of high temperature resistant casing is coated with organic silica gel, its main chain is – Si-O -, and there is no double bond, so it is not easy to be decomposed by ultraviolet and ozone. High temperature bushing has good electrical insulation performance, and its dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistance coefficient and surface resistance coefficient are among the best among the insulation materials, and their electrical performance is little affected by temperature and frequency. Therefore, they are a kind of stable electrical insulating materials, which are widely used in electronic and electrical industry.
7. Flame retardant, reduce the fire rate and spread speed
If the pipeline is conveying flammable or toxic medium, it is easy to cause fire or casualties in case of leakage; Cables are often burned due to local high temperature; The high temperature resistant and fireproof sleeve is made of extremely high temperature resistant glass fiber, and the surface silica gel is added with appropriate flame retardant and other special raw materials, so that it has excellent flame retardancy. Even if a fire occurs, it can prevent the spread of the fire and protect the integrity of the internal pipeline for a long time, providing sufficient time for the rescue of important information such as data and information.
