Insulation suits, also known as thermal protective clothing, are important personal protective equipment. They refer to protective clothing that can prevent itself from being ignited, flame burning, and smoldering after contact with flames and hot objects to protect the human body from all kinds of injuries. Oil, chemical, metallurgy, glass and other industries protective garments for high temperature furnace operations and fire fighting clothing for fire protection and forest fire prevention.
The difference between firefighters refuge clothes and insulation clothes
Difference 1: whether the clothing can withstand flame burning; insulation clothing can not touch the flame, otherwise it will be damaged; shelter clothing can withstand the flame burning.
Difference 2: Insulation suits cannot enter the fire; fire suits can enter and cross the fire.
Difference 3: Resistance to radiant heat temperature, insulation clothing is generally 1000 degrees, and fire escape clothing is generally 1800 degrees.
Difference 4: Material and design are different. The material of the fire escape suit is usually more than three layers, and both the outer layer and the middle layer have flame resistance. Insulation material does not have the ability of milk flame, and it pays more attention to the ability of the intermediate insulation layer.
Difference 5: Different standards.
Mistakes in the selection of thermal insulation clothing
1) Insulation suits as fire suits Insulation suits can be made in the same manner as fire suits, but the suits cannot touch the flame and they cannot enter the fire. Otherwise, clothing will be damaged.
2) Treating industrial thermal insulation clothing as fire protection and heat insulation clothing Industrial insulation clothing is generally lower in fabric safety performance than fire and heat insulation clothing. The use of glass fiber composite aluminum foil, easy to fall off after use, low thermal radiation reflectivity (> 70%) and fire insulation clothing is usually used aramid high temperature materials, surface aluminum foil is sprayed onto the substrate at high speed, The surface is smooth, not easy to fall off, and the heat radiation reflection efficiency is high (>90%).
The mask of the window is different. The mirror of the fire insulation clothing adopts gold-plated glass, and its thermal radiation reflectivity is more than 95%. The industrial insulation clothing usually adopts a chrome glass mirror or a polyester transparent mirror. For thermal radiation greater than 500 degrees, Can not be a good reflection, easy to burn into eyes and face.
3) The difference between high-temperature protective clothing and thermal insulation clothing The difference between thermal insulation clothing and high-temperature protective clothing is mainly due to the difference in ambient temperature and fire source conditions.
High-temperature protective clothing is mainly used in environments where the ambient temperature is within 300 degrees. Does not emphasize thermal insulation.
Insulation suits are mainly used for ambient temperatures greater than 300 degrees, or where metal melt splashes occur; emphasis is placed on the reflection and reflection efficiency and thermal insulation of heat radiation.
The reflective heat radiation effect of high-temperature protective clothing is poor, and the insulation clothing can generally reflect the efficiency greater than 70%, and the heat insulation effect should be less than 25 degrees temperature rise/30 minutes.
4) Insulation suits and fire protection suits The function of insulation suits is to isolate heat. More than 70% of the radiant heat of the fire source is reflected off, and the remaining heat is blocked by the heat insulation layer. The temperature rise in the packaged garment is not more than 25 degrees.
Insulation suits are not suitable for use by firefighters during firefighting and rescue operations with radioactive materials, biological substances and dangerous chemicals.
