Introduction to the atomization test
Atomization -related definition
◆ atomization: The condensation phenomenon formed by the organic matter and vaporized substances from the internal decoration of the car on the glass , Especially on the windshield.
◆ ingredients that can condense ingredients G: The weight of the weight of the aluminum foil with atomization-condensate and the weight of the aluminum foil without atomization-condensate.
◆ Atomizing value F: The 60O-reflex coefficient of the glass plate with a atomization-condenser is the percentage of 60O-reflex coefficient of the same glass plate without atomization-condensate.
◆ Misty H: The ratio of the scattering light flux of the scattered light in the direction of the incident light through the sample is expressed by the percentage.
The atomization performance test device is mainly composed of high temperature constant temperature tank, low temperature constant temperature tank, cooling plate, fogging cup, fogging, glass plate. Global glory (gloss method), fogging meter (fogging method), a balance (weight method) with a accuracy of 0.01mg, sampler and some attachments can be completed, which can complete the test process of sampling, heating, condensation, and testing.
Test principle of atomizer
The test principle of the atomizer test is heated in the fog cup, and the volatile gas has been cooled and cooled Glass plate or aluminum foil condenses. After the condensation process is over, remove the glass plate or aluminum foil, and measure the atomization value or weight of the condensation ingredients of the glass plate or aluminum foil, and compare it with the data before unimaginas to obtain the fabricization volatilization characteristics of the sample.
atomization test criteria
The fog of the car interior material will hinder the sight of the windshield, and it will affect the driving under the disadvantaged light conditions. Safety. At the same time, because the condensate components are mostly harmful organic volatiles, the height of fog can also reflect the height of organic hair products in the interior material. Therefore, automobile manufacturers in various countries have formulated restrictions on the foggy of automotive interior materials.
Misty method/weight method
Common test standards and precautions
Send inspection for inspection for inspection Sample requirements: The test surface of the sample needs to be marked
The amount of sample provided by the customer: detect sample detection items*3
The sample is a thin film, leather, cloth and other soft samples: sampling with sampling: sampling Test samples for tailoring and tailoring a circular sample with a diameter of 80mm.
The sample is liquid, powder, and paste: The weight of each portion is (10 plusmn; 0.1) grams.
