Main features and applications of heaters

Thermal dummy can test the detailed data system. The dummy itself does not bring a finger and face. The dummy has a higher strength, and the pure nickel nickel wire is placed from the fingers to the nasal cavity. The independent smart circuit guarantees the accuracy of the measurement process. Only circuitry within each part ensures the accuracy of the measurement, the built-in thermal conductive system ensures good uniformity. At the same time, the fake person can be divided into two parts, easy to transport.

1. The body model is divided into head, torso, limbs, etc. A total of 17 sections, each section has insulation and fine-tuning heaters in each segment, constant power control Doing surface heating, constant temperature control;

2. In control software part, the internal heat of the human model, the temperature insulation performance of the garment, and the surface temperature assessment of the human body model, heat dissipation hot value calculation, etc. Handling various measurement materials and recording and statistical processing;

3. A resin having a small thermal capacity when producing a thermal capacity, and can quickly treat the thermal reaction and heat exchange process of the human body;

4. Heat nickel wire sensor, connected to the entire system, measuring the average temperature has good sensitivity in each paragraph;

5. Articles, shoulders and knees can be bent and change into stand or sitting, easy to disassemble clothes

6. The lifts of the human body model can be easily moving the human body model.

The main application:

In the dangerous environment of the 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. The thermal physical properties of the clothing not only the hot physical properties of the fabric itself not only change, but also after leaving the flashfire environment, because the surface temperature of the clothing will remain in a higher range, and with the clothes And the temperature difference between the surface of the human body, continuously producing heat transfer, the surface temperature of the human 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

The thermal protection performance of clothing is not only dependent 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.
