The heat radiation performance is an important performance index of flame retardant products, accurate determination of its protective properties, which it is very important to select materials, research new products and improve the processing technology.
Method A: The sample is mounted in a separate frame and exposed to a heat radiation source for a certain time. The intensity of the thermal radiation is controlled by adjusting the distance between the sample and the radiation source. After the test, the visual changes at each level of the sample were examined.
Method B: The sample is fixed to a calorimeter and exposed to a thermal radiation source. The time required for the temperature of the calorimeter to rise by 12°C and 24°C, respectively, was measured.
On the basis of these data, the heat flux rate is calculated by the difference of the heat fluxes between the transfer and the incident.
The cooling system provides a continuous flow of water fromthe inlet and outlet of the testing machine.
