Temperatures around 40°C are bearable for ordinary people, but temperatures of 400°C are probably unbearable. Firefighters walked through seas of flames with temperatures as high as 400°C or even higher when carrying out rescue operations. In such a high temperature environment, the high temperature resistance of firefighting clothing is particularly important because it is directly related to the safety of firefighters.
At present, ordinary fire-proof clothing is mainly based on fabric choices. They use composite aluminum foil fire-proof cloth, flame-retardant insulation felt, comfort layer or composite aluminum foil fire-proof cloth, and comfort layer. However, ordinary fire-proof clothing can allow firefighters to The time spent in the sea of fire will not exceed 3 minutes. Because the flames in a fire are usually very hot, they also release a lot of heat radiation while burning. This kind of heat radiation can reach hundreds of degrees Celsius. Ordinary fire-proof clothing can be flame-retardant, but its thermal insulation is not strong. If firefighters shuttle through the sea of fire for a long time, their lives will be threatened.
Compared with ordinary fire-evading clothing, the biggest feature of Blue Ice Cooling Fire-Avoiding Clothing is that it not only avoids fire, but also cools down. By combining blue ice cooling materials and technology with existing aerospace insulation and fireproof materials, the time for firefighters to penetrate into the sea of fire is extended and the safety of firefighters is ensured. In terms of fire protection, Blue Ice cooling fire protection clothing uses fire-resistant cloth used in aerospace. The biggest feature of fire-resistant cloth is flame retardant. It is composed of multiple layers of flame-retardant fibers and has strong flame-retardant ability. It is precisely because of this characteristic of fire-resistant cloth that it is possible for firefighters to enter the sea of fire for rescue. Even under the high temperature of 1600℃, the refractory cloth will not react in any way.
Speaking of blue ice, it is not a solid form of water. Blue Ice is a new green and environmentally friendly polymer energy storage material developed using the world’s leading high and new technologies. It has a honeycomb structure of polymer polymer inside. It is a blue, transparent and soft colloid at normal temperature. Its heat capacity is 2.3 times that of water. It has the dual functions of efficient cold storage and heat storage, and can quickly cool down and relieve fever.
Blue ice is an efficient carrier for cold and heat storage. Its cold or heat storage process is mainly a physical process of energy conversion, with the characteristics of rapid absorption and slow release. We made the blue ice into fire-proof clothing and designed the inner clothing and interlayer, and put the blue ice as the liner in the interlayer. Usually I put the blue ice liner in the freezer to freeze, and then take it out to wear when going into the fire. Through this design, the Blue Ice Cooling Fire Avoidance Suit has a cooling effect. When the heat-resistant temperature of the exterior reaches about 15,000°C, the internal space temperature of the fire protection suit does not exceed 30°C.
