The role of combustion fake people in the field of thermal protection

In the dangerous environment of fire, people need to avoid fire damage by wearing heat protection suit. Heat protective clothing is widely used in protecting firefighters, steelmaking workers, and workers engaged in other high temperature dangerous places. As clothing increases in the flame, the surface temperature of the clothing gradually increases due to the direct burning of the flame, and a large amount of heat transfer causes the air layer and the surface temperature of the human body. Costumes not only the hot physical properties of the fabric themselves not only change in the flame burning, but also affect the thermal protection performance, and after leaving the flashfire environment, since the surface temperature of the garment will remain in a higher range,

The temperature difference is formed with the temperature of the surface and the surface of the human body, and the surface temperature of the heat transfer body continues to rise. Studies have shown that burns may occur after the end of the flashfire, and the energy stored in additional fabric is an important factor for predicting burns. Therefore, even if the heat shield can abut the flame short time combustion, the clothing can still be caused by burn during the cooling process. Therefore, research on the temperature change of the human surface after burning is particularly important.

Research on the use of combustion dumns on multi-storey protective clothing shows that the outermost surface has an important impact on the protection of multi-storey protective clothing. Test using TPP instruments, it was found that the heat source of low-heat flow over a long time is more likely to burn more than a severe combustion of a short time. During the actual wear, the thermal protection performance of clothing relies on the performance of the fabric itself, but also needs to be considered from the aspects of clothing style design, specifications, and dressing attitude. In order to simulate the human body in the actual fire in the actual fire, the test method of the combustion dummy is exhibited in the field of thermal protection in the field of thermal protection.
