Glass fiber tube (fireproof casing)
Fireproof casing, also known as high-temperature resistant casing, silicone rubber glass fiber casing, using high-purity alkali-free glass fiber compiled into a tube and then coated with organic silicone on the outer wall of the tube by vulcanization treatment. After vulcanization, it can be used for a long time in the temperature range of -65°C to 260°C and maintain its soft and elastic properties.
Fireproof casing performance
The synthesis of special high-temperature resistant materials determines that the fireproof casing has many characteristics that are difficult to be replaced by other similar materials: high-temperature resistance, thermal insulation, flame retardant, electrical insulation, chemical stability, weather aging resistance, cold resistance, water resistance, oil resistance, ozone resistance, voltage resistance, arc resistance, corona resistance, etc., especially the safety and environmental performance, is the best alternative to asbestos and other hazardous products.
Types of fireproof casing
Tubular fireproof sleeving
Generally suitable for the protection of shorter or straighter pipelines, cable protection, automotive wiring harnesses, generator sets in common use, installed firmly, not easy to disassemble, sealing, insulation, heat insulation, the moisture-proof effect is better.
Winding-type fireproof sleeve
It is mainly used for high-temperature protection of irregular protected objects such as valves and bent pipes, and it is convenient to wrap.
Buckle-type fire casing
The advantage is that it is easy to disassemble and install without stopping the equipment and disassembling the cable, etc. The internal sewing has fire-resistant and flame-retardant adhesive buckle tape, and the casing can be glued from the middle to play the role of sealing insulation without affecting the production of equipment and saving installation time. Commonly used in large smelting equipment, high-temperature metal hoses are also used.
Fireproof casing features and applications
1. Safety and environmental protection, protection of workers' health
Alkali-free glass fiber itself has strong tensile strength, will not wrinkle break, vulcanization resistance, smoke-free halogen-free non-toxic, pure oxygen non-combustible, good insulation characteristics, and then cured by organic silica gel, to strengthen its safety and environmental performance, effective protection of workers' human health, reduce the incidence of occupational diseases. Unlike asbestos products, which are extremely harmful to the human body and the environment.
2. Superior high-temperature resistance
The surface silicone structure of the fireproof casing contains both "organic group" and "inorganic structure", and this special composition and molecular structure make it combine the characteristics of organic and inorganic substances in one. Compared with other polymer materials, its most outstanding feature is its high-temperature resistance. With the silicon-oxygen (Si-O) bond 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 in silicone is 121 kcal/g molecule, so its thermal stability is high, and the molecules at high temperature (or radiation exposure) The chemical bonds do not break or decompose under high temperature (or radiation exposure). Silicone is not only resistant to high temperatures, but also low temperatures, and can be used in a wide range of temperatures. Both chemical properties and physical and mechanical properties change very little with temperature.
3. Anti-splash, multiple protection
In the smelting industry, the medium temperature in the electric furnace is extremely high, easy to form high-temperature spatter (welding industry, too), after cooling and solidification in the pipe or cable to form slag, will make the pipe or cable outer layer of rubber hardening, and eventually brittle rupture. After multiple silicone-coated fire sleeves, it can achieve multiple safety protection, the highest temperature resistance can be up to 1300 degrees Celsius, can effectively block molten iron, molten copper, molten aluminum and other high-temperature molten spatter, prevent the surrounding cables and equipment from being damaged.
4. Thermal insulation, energy saving, radiation resistance
In high-temperature workshops, many pipes, valves, or equipment, their internal temperatures are very high, if not covered with protective materials, it is easy to cause burns to personnel or heat loss, etc. Fireproof casing, with better thermal stability than other polymer materials as well as irradiation resistance and thermal insulation, prevents accidents, reduces energy consumption, also prevents the heat of the medium inside the pipe from being directly transferred to the surrounding environment, and makes the temperature of the workshop too high, saving cooling costs.
5. Moisture-proof, oil-proof, climate-proof aging, anti-pollution, extend the service life of the equipment
The fireproof casing has strong chemical stability, silicone, oil, and water, acid, and alkali substances do not react, within 260 ℃, can be used for a long time and not aging, the service life of the natural environment can reach decades, can maximize the protection of these occasions in the pipeline, cable, and equipment, greatly extending its service life.
6. Ozone resistance, voltage resistance, arc resistance, corona resistance
Because the surface is coated with organic silica gel, its main chain is -Si-O- and no double bond exists, so it is not easily decomposed by ultraviolet light and ozone. Fireproof sleeving has good electrical insulation properties, and its dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistance coefficient, and surface resistance coefficient are among the top insulating materials, and their electrical properties are little affected by temperature and frequency. Therefore, they are a stable electrical insulating material and are widely used in the electronics and electrical industry.
7. Flame retardant, reduce the incidence of fire and the rate of spread
If the pipeline conveys flammable or toxic media, it is easy to cause fire or casualties when leakage occurs; the cable also often burns due to local high temperature; fireproof sleeving is made of extremely high-temperature resistant glass fiber woven, and the surface silica gel is added with appropriate flame retardants and other special raw materials, making it extremely good flame retardancy. Even if a fire occurs, it can stop the spread of fire and still protect the internal pipeline intact for a longer period, giving the possibility and sufficient time to rescue important information such as data and materials.
8. Easy to install and use
When installing the thermal fire sleeve, there is no need to disable the equipment or disassemble the hoses and cables. Another advantage is that it can be installed on-site in the factory to ensure proper fit and structural integrity.
Commonly used areas
High-temperature areas, heated area cables, fluid lines, mill cables, oil pipes, sawn perimeter cables, generator sets, electrical voltage equipment, large buildings, hydraulic systems, automotive wiring harnesses, and exhaust pipes in other industries such as steel, smelting, marine, and chemical.
With its excellent performance, fireproof casing products are not only used as special materials for aerospace, cutting-edge technology, and military technology sectors, but also used in various sectors of the national economy, and their applications have been extended to metal smelting, construction, electrical and electronic, textile, automobile, machinery, chemical, and light industry, etc. With the improvement of the production level of domestic organosilicon and other raw materials, there will be a huge space for development.
