Exploring the meaning of fake people's burning

In the dangerous environment of fire, people need to avoid fire damage by wearing heat protection clothing. 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. Clothing in the flame , not only the hot physical properties of the fabric itself will change, not only the thermal protection performance, and after leaving the flashfire environment, since the surface temperature of the garment will remain in a higher range, and 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.

In order to simulate the human body in the actual firefield and safe and accurate measurement of the surface temperature of the body, the test method of the combustion fake person has shown an advantage in the field of thermal protection. Applications.

Research has shown that burns may occur after the end of the flashfire, and the energy stored in additional fabric is an important factor in 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.

The above is the detailed information about the combustion dummy for you, of course, if you want to pay more in depth, you will come to consult: info@qinsun-lab.com.
