Fire sleeve features and application

1. safety and environmental protection, protection of workers’ health
E-glass fiber itself has an exceptionally strong rally, will not wrinkle break resistance, curing, smoking halogen-free non-toxic, non-flammable oxygen, good insulation properties, and then after the silicone cured, more to strengthen its safety and environmental performance, effective protection workers’ health, reduce the incidence of occupational diseases. Unlike asbestos products such great harm to humans and the environment.
2. Superior high temperature performance
Fireproof silicone casing surface structure contains both “organic group”, also contain “inorganic structure”, this particular composition and molecular structure so that it sets the characteristics of organic matter and inorganic substances 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.
3. splash, multiple 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, pipe or cable will make the outer rubber hardening, and finally brittle fracture. Further damage to unprotected devices and cables, through multi-channel silica-coated fireproof casing, can achieve multiple security, the highest temperature up to 1300 degrees Celsius, can effectively block the molten iron, molten copper, aluminum melting and other high temperature melt splashing, to prevent surrounding cables and equipment was damaged.
4. insulation, energy saving, radiation-resistant
In the high-temperature workshop, 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. Fire sleeve, has a 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 The temperature is too high, saving cooling costs.
5. moisture, oil, anti-weathering, pollution prevention, extended equipment life
Fire sleeve has a strong chemical stability, the silicone oil and water, acid and other substances are not react within 260 ℃, long-term use without aging, life natural environments up to several decades, can be maximum protection of pipes, cables and equipment within these occasions, greatly extending its life.
6. ozone resistance, voltage, arc resistance, corona resistance
Because the surface of the silicone coating, the main chain of -Si-O-, unparalleled key exists, it can not easily be decomposed by ultraviolet light and ozone. Fire 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, is widely used in electronic, electrical industry.
7. retardant, reduce the incidence and spread of fire speed
If the pipeline transportation of flammable or toxic media medium, can cause fire or casualties occur; cable also often occurs due to local high temperature combustion; fire protection sleeve using extremely high temperature of the glass fiber woven surface silica added with appropriate special materials such as flame retardants, it has excellent flame retardancy. Even if fire occurs, it can prevent the spread of fire, can still protect the internal pipeline intact for a long time, to rescue important information data, information and so provide a possible and sufficient time.
8. easy installation
When installing hot fire casing, you do not need to disable the device does not need to be removed hoses and cables. Another advantage is that can be field installed at the factory to ensure the integrity and proper adaptation structure.
