Analysis of the application characteristics of warmer dummy

Thermor dummy can test the detailed data system. The dummy itself does not have a higher strength, and the inside of the dummy places a pure nickel wire close to 700m from the finger to the nasal cavity, and the independent smart circuit guarantees the measurement process. Accuracy. 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. Qinsun will explain from two angles.

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 thermal protective clothing can abut the flame short time, the clothing can still cause burn in 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. Using TPP instruments into

row test, it is found that long-term low heat flowThe heat source exposure is more likely to burn more than a fierce combustion.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.
