How much do you know about fire insulated clothing?

Thermal protective clothing is a garment worn in a high temperature environment, which can promote the distribution of body heat and prevent heat stroke, burns and burns and other hazards. The protective clothing. Therefore, thermal protective clothing must have flame retardant, liquid repellent, no molten droplets produced when burning, and can maintain the integrity of the clothing when it is heated. and wearing comfort and other performance.

According to the use of different temperatures, thermal protective clothing can be divided into fire protection clothing> 1000 ℃, high temperature protection clothing <200 ℃, thermal protective clothing for fire extinguishing, fire extinguishing and fire extinguishing. Service> 800 ℃, industrial suit for thermal insulation <800 ℃, fire suit for firefighters <200 ℃ and so on five types. In general, the following misunderstandings should be borne in mind when choosing

1 、 Take industrial clothing for thermal insulation as clothing for fire insulation

The safety performance of the fabric of industrial suits for thermal insulation is usually lower than that for fireproof suits, and a laminated aluminum foil on glass fibers is used, which falls easily after use and thermal radiation. Low reflectivity. The basic material of thermal insulation clothing for fire extinguishing is usually made of aramid material resistant to high temperatures, and the aluminum foil on the surface is sprayed on the basic material at high speed.

The surface is smooth, it is not easy to fall off, and the efficiency of thermal radiation reflection is high. The surface mirror of the window is different, the surface mirror of fire-retardant fire-fighting clothing accepts gilded glass, and the rate of reflection of thermal radiation is greater than 95%, the surface mirror of industrial clothing for thermal insulation usually chrome glass or polyester transparent mirror, which can not reflect heat radiation greater than 500 degrees, and it is easy to cause burns to the eyes and face.

2 、 Take heat-insulating clothing as fireproof clothing

The style of thermal insulation clothing can be the same as fireproof clothing, but thermal insulation clothing cannot come into contact with the flame and cannot enter the fire field operation, as otherwise it will damage the clothing.

3 、 Confusion of heat-insulating clothing and fire-resistant and chemically resistant clothing

Thermal suits are not suitable for firefighters in the process of extinguishing fires and rescuing both radioactive substances, biological substances and hazardous chemicals in contact with the use of wear.

4 Mix high temperature protective clothing with thermal clothing

The difference between thermal suits and high-temperature protective suits mainly lies in the difference between ambient temperature and fire conditions, high-temperature protective suits do not reflect heat radiation well. Insulated suits can generally reflect 70% of heat radiation.

Protective clothing for high temperatures is mainly used in environments where the ambient temperature is lower than 300 degrees Celsius, while thermal protective clothing is mainly used in environments where the ambient temperature is higher than 300 degrees Celsius. Ambient temperature or place of spraying of molten metal.
