What industry is Comfortable Thermal Manikin mainly used in?

Shanghai Qiansun Comfortable Thermal Manikin can test detailed data systems. The dummy itself does not have fingers and faces. The dummy has higher strength. A pure nickel wire of nearly 700m is placed from the fingers to the nasal cavity inside the dummy. The independent intelligent circuit guarantees the accuracy of the measurement process.

main application:

In the dangerous environment of the fire field, people need to wear thermal protective clothing to avoid fire damage. Thermal protective clothing is widely used to protect firefighters, steel workers, and workers engaged in other high-temperature hazardous locations. As the clothing is exposed to the flame for an increase in time, the surface temperature of the clothing will gradually increase due to the direct burning of the flame, and a large amount of heat transfer makes the air layer under the clothing and the surface temperature of the human body rise at the same time. Not only will the thermal physical properties of the fabric itself change under the flame burning, which will affect its thermal protection performance, but also after leaving the flash fire environment, the surface temperature of the clothing will still remain in a higher range, and will be in contact with the clothing underneath. And the temperature of the surface of the human body forms a temperature difference, and the continuous heat transfer causes the surface temperature of the human body to continue to rise. Studies have shown that burns may occur after the flash fire is over, and the energy stored in the fabric is also an important factor in predicting burns. Therefore, even if the thermal protective clothing can withstand the flame burning for a short time, the clothing can still cause burns during the cooling process. Therefore, it is particularly important to study the changes in the surface temperature of clothing and human body after burning.

Comfortable Thermal Manikin

Research on multi-layer protective clothing using burning dummy shows that the outermost fabric has an important influence on the protective performance of multi-layer protective clothing. Using TPP instrument to test, it is found that long-term exposure to a heat source with low heat flux is more likely to cause burns than short-term violent combustion. In the actual wearing process, the thermal protection performance of clothing not only depends on the performance of the fabric itself, but also needs to be comprehensively considered from the aspects of clothing style design, specifications and dressing posture. In order to simulate the situation of the human body in the actual fire field as realistically as possible and to safely and accurately determine the surface temperature of the clothing and the human body, the test method of the burning dummy has shown its advantages and has been widely used in the field of thermal protection.
