In the production and functional improvement of automobile interior accessories, it is likely that small molecular substances will be introduced into it, and these introduced substances are volatile, especially when the temperature inside the car is high, these substances are more volatile. The small molecular substances volatilized from the interior accessories may float in the air, pollute the air environment inside the car, endanger human health after being inhaled, or condense on the windows of the car, adversely affecting the driving line of sight and threatening driving safety. Therefore, automobile manufacturers and automobile accessories manufacturers need to carry out quality inspection on relevant product materials before leaving the factory. For high-temperature atomization performance testing of leather materials for car seats, high and low temperature boxes are used as supporting test equipment, which mainly provide simulated ambient temperature. The effect of accelerating the volatilization of small molecular substances in automotive interior parts.

Test principle: The test is to increase the temperature of the high and low temperature box to accelerate the volatilization of small molecular substances in automotive interior parts to shorten the volatilization time. During the test, the sample is placed in a fogging cup, and aluminum foil or glass is placed above the fogging cup. Place the fogging cup in the heating tank of the fogging tester for heating, and the aluminum foil or glass plate above is cooled by the cooling device. The volatilized gas in the sample will condense on the surface of the cooled aluminum foil or glass plate , The fogging performance of the sample is obtained by testing the optical properties of the glass plate or the weight change of the aluminum foil before and after condensation.
