Haotian Brand Fireproof SleeveFeatures and Applications
1.Safe and environmentally friendly, protecting workers' health
Alkali-free fiberglass itself has strong tensile strength, is wrinkle-resistant and breakage-resistant, sulfur-resistant, produces no smoke, halogen-free, non-toxic, is pure oxygen non-flammable, and has good insulation properties. After being cured with organic silicone, its safety and environmental characteristics are further enhanced, effectively protecting workers' health and reducing the incidence of occupational diseases. Unlike asbestos products, which pose significant harm to human health and the environment.
2.Excellent high-temperature resistance
The surface of the high-temperature sleeve has an organic silicone structure that contains both'organic groups' and 'inorganic structures'. This special composition and molecular structure endow it with the characteristics of organic materials and the functionalities of inorganic materials. Compared to other polymer materials, its standout feature is high-temperature resistance. With a silicon-oxygen (Si-O) main chain structure, C-C bond energy is 82.6 kcal/mole, while Si-O bond energy in organic silicone is 121 kcal/mole, thus its thermal stability is high, and the chemical bonds of the molecules do not break or decompose under high temperatures (or radiation exposure). Organic silicone not only withstands high temperatures but also low temperatures, allowing it to function effectively across a wide temperature range. Both its chemical and physical mechanical properties show little variation with temperature changes.
3.Splash-proof, multiple protections
In the smelting industry, the medium temperature in electric furnaces is extremely high, easily causing high-temperature splashes (the same is true in the welding industry). After cooling and solidifying, these splashes can form slag on pipes or cables, leading to hardening and eventual brittleness and cracking of the outer rubber layer of pipes or cables. This can damage unprotected equipment and cables. The high-temperature sleeve, coated with multiple layers of silicone, provides multiple safety protections, with high-temperature resistance up to 1300 degrees Celsius, effectively blocking the splashes of molten iron, molten copper, molten aluminum, and other high-temperature molten materials, preventing damage to surrounding cables and equipment.
4.Heat insulation, energy saving and consumption reduction, radiation resistance
In high-temperature workshops, many pipes, valves, or equipment have very high internal temperatures. Without protective materials, this can easily lead to personnel burns or heat loss. The Haotian high-temperature sleeve offers better thermal stability than other polymer materials, along with radiation resistance and heat insulation, preventing accidents and reducing energy consumption. It also prevents the heat of the medium inside the pipes from directly transferring to the surrounding environment, which could increase workshop temperatures and save cooling costs.
5.Moisture-proof, oil-proof, climate aging resistance, pollution resistance, extending equipment service life
The high-temperature sleeve has strong chemical stability, and organic silicone does not react with oil, water, acids, or bases, remaining usable without aging for a long time at temperatures below 260℃. Its service life in natural environments can reach several decades, maximizing the protection of pipes, cables, and equipment in such environments, significantly extending their service life.
6.Ozone resistance, voltage resistance, arc resistance, corona resistance
Due to the surface coating of organic silicone, which has a main chain of -Si-O-, the bonds present are not easily decomposed by ultraviolet light and ozone. The high-temperature sleeve has good electrical insulation properties, with dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity, and surface resistivity all ranking among the top of insulating materials, and their electrical performance is minimally affected by temperature and frequency. Therefore, they are stable electrical insulating materials widely used in the electronics and electrical industries.
7.Flame retardant, reducing the incidence and spread speed of fires
If the medium transported within the pipes is flammable or toxic, a leak can easily cause fire or casualties; cables also frequently catch fire due to localized high temperatures. The high-temperature sleeve is woven from extremely heat-resistant fiberglass, and the silicone surface is added with appropriate flame retardants and other special materials, giving it excellent flame retardancy. Even in the event of a fire, it can prevent the spread of flames and still protect the internal pipelines intact for an extended period, providing ample time for the rescue of data, materials, and other important information.
