automotive interiors fogging tester Test principle: the sample in the fog cup was heated and began to volatilize, volatile gas has been cooled in the cooling of the glass or aluminum foil on the condensation. After the completion of the condensation process, the glass plate or aluminum foil was removed and the atomization and volatilization characteristics of the sample were obtained by measuring the atomization value or weight of the condensing component of the glass plate or aluminum foil and comparing it with the data before being condensed.
Measurement of the automotive interior fogging testing machine:Gloss method: the sample in the fog cup heated by the evaporation of the gas condensed in the low-temperature glass plate, through the glass plate before and after condensation of the gloss value of the comparison and calculation, can be obtained into the fog of the sample. (Standard)Haze method: the sample in the fog cup heated by the evaporation of the gas condensed in the low-temperature glass plate, through the glass plate before and after the condensation value of the condensation and calculation, can be obtained into the fog of the sample. (Optional)Gravimetric method: the sample in the fog cup heated by the evaporation of the gas condensed on the low-temperature aluminum foil, by weighing the weight of aluminum foil before and after the change, we can get the sample atomization - coagulation weight. (Standard, balance purchase)
Fogging index test instrument operation steps:Prepare the sample → open the high and low temperature bath and reach the set temperature → clean the fog cup and fog glass plate → place the sample → place the fog glass or aluminum foil → place the cooling chamber → two slots to keep the set temperature and normal Run to test request time → Remove the glass or aluminum foil for a specified time → Measure the gloss, haze or weight of the foil • Compare the data and get the final result.
