1. The advantages of fireproof sleeve

The fireproof sleeve is made of high-purity alkali-free glass fiber woven into a tube, and then the outer wall of the tube is coated with organic silica gel and vulcanized. 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. The alkali-free glass fiber itself has the characteristics of strong tensile force, no wrinkle, vulcanization resistance, smoke-free, halogen-free, non-toxic, pure oxygen, non-combustible, and good insulation. Workers are healthy and the incidence of occupational diseases is reduced.

2. The use of fireproof sleeve to achieve the best protection effect

In the high temperature workshop, how to achieve the best protective effect is the first problem we must consider. There are many pipes, valves or equipment in the high temperature environment, and the internal temperature is very high. If the protective material is not covered, it is easy to cause burns or heat loss, etc. The fireproof casing has better thermal stability, radiation resistance and thermal insulation than other polymer materials, preventing accidents, reducing energy consumption, and preventing the heat of the medium in the pipeline from being directly transferred to the surrounding environment and causing the workshop to be damaged. The temperature is too high to save cooling costs.

The fireproof sleeve has strong chemical stability. The silicone does not react to oil, water, acid and alkali and other substances. It can be used for a long time without aging within 260 °C. The service life in the natural environment can reach several decades. To maximize the protection of pipes, cables and equipment in these occasions, greatly extend their service life. Because the surface 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 light and ozone. Fire sleeves have good electrical insulation properties, its dielectric loss, withstand voltage, arc resistance, corona resistance, volume resistivity and surface resistivity are among the best in insulating materials, and their electrical properties are affected by temperature and frequency. The impact is small. Therefore, they are a stable electrical insulating material and are widely used in the electronics and electrical industries.

If the flammable medium or toxic medium is transported in the pipeline, it is easy to cause fire or casualties in the event of leakage; the cable often burns due to local high temperature; There are special raw materials such as appropriate flame retardants, which make it have excellent flame retardancy. Even if a fire occurs, it can prevent the spread of the fire, and still protect the internal pipeline from being intact for a long time, providing possible and sufficient time for the rescue of important information such as data.
