Contact Heat Transmission Tester

The Protective Clothing Thermal Conductivity Tester is a specialized device used to evaluate the thermal conductivity performance of thermal insulation clothing when it comes into contact with a heat source. By simulating a high-temperature contact environment, it quantifies the material's resistance to heat conduction, providing a scientific basis for the design, production, and use of thermal insulation clothing.

Applications

In the medical field, it helps develop and screen more comfortable medical protective clothing to prevent heat accumulation and discomfort caused by long-term wearing for medical staff, and reduce the risk of heat stroke; in the industrial and fire protection fields, it can evaluate the thermal insulation effect of high-temperature protective clothing to ensure the safety of workers in high-temperature environments and prevent heat injuries.

Technical Parameters

Test Procedures

Before the experiment, the heating cylinder was heated to the set temperature, and the sample was mounted onto the calorimeter. The calorimeter was moved towards the heating cylinder at a speed of 5 mm/s, and a load of 45 N was applied upon contact. The temperature rise time threshold of 10°C was measured using the calorimeter. The temperature of the heating cylinder could be adjusted from room temperature to 500°C.
