【Technical Parameters】
1．Testing Methods:
Method A: Evaporative Hot Plate Method;
Method B: Static Flat Plate Method;
Testing of heat absorption and heat release of phase-change fabrics (a breakthrough technology, an international initiative).
2．Test Plate Size: 200×200×5mm;
The heating test plate assembly consists of three parts: the test plate, the thermal guard ring and the base plate. The thermal guard ring is located around the test plate, and the base plate is located below the test plate.
The test plate is a microporous porous plate made of special stainless steel powder metallurgy, which highly simulates the sweating effect of human skin. At 20℃, when a light beam with a wavelength range of 8μm to 14μm is vertically irradiated on the surface of the test plate and measured in a hemispherical reflection mode, the emissivity of the test plate surface is higher than 0.4.
