The substances that can be volatile in the car interior material volatilize into the air. The hot air encounters cooling objects, and the volatile substances are condensed into liquid attached to the cooling object. The process of becoming a fog is the process of volatilization of material-condensation process.
Put the sample in the fog cup, cover the foggy cup with a sealing ring and glass ring (or a heavy aluminum foil), install the cooler on it on it Essence The foggy cup is placed in the thermostat. The sample was heated in the foggy cup, and the volatile items in it began to volatilize, and the evaporation gases condensed on the glass plate that had been cooled and cooling. After the condensation process is over, remove the glass board and place the prescribed time in the state specified in the standard. Use a gloss to measure the gloss value of the glass board, and compare it with the initial gloss value of the glass board before the test, so as to get the test tested The fog value of the material; or the metering of the glass plate parallel light after testing the test of the light transmittance instrument, compared with the parallel light of the glass plate before the test, can get the glass blurred of the tested materials.
The sample was heated in the fog cup, and the emile gas condensed on the aluminum foil that had been cooled and cooling. After the condensation process is over, remove the aluminum foil and use the electronic balance to measure its quality. After subtracting the quality of the aluminum foil itself, the quality of the atomization condensate of the test material — condense group points.
