Automobile interior decoration materials such as leather, plastic, textile and adhesive materials, etc., contain some volatile materials, especially in the sunlight, the temperature inside the car increases, will aggravate this kind of volatile. Volatile gas condensation in the car window or windshield, resulting in poor vision, will affect the driver's vision and driving safety; There are also some volatile substances can be harmful to the human body, affecting the driver's health. In order to control the production of volatile substances reasonably, it is necessary to carry out atomization test on the materials used in automobile interior decoration.

Spray test instrument generally follow the standards of DIN 75201, divided into gloss method (A) and weight method (B) two kinds of test methods, measurement process is: put the material under test in the bath, specially in the high temperature liquid glass material volatile substances in the condensation on the low temperature on the glass or aluminum foil placed the glass mouth, determination of gloss value before and after the glass into the fog, A method of test results, weighing the weight of the aluminium foil before and after condensation test results can be obtained B method.

Atomization test instrument is applicable to the evaluation of evaporation of volatile components of automotive and aircraft interior materials, such as automotive interior plastic parts, polyurethane, textiles, leather, adhesives, nonwovens, thermal plasticity elastomers and other materials under high temperature, and can also be used for the measurement of xenon lamp high temperature atomization phenomenon [2].

Basic applications:

Automobile interior decoration: it is suitable for automobile interior decoration material, such as instrument panel, knob, seat cushion, floor leather, ceiling material, etc.

Plastic granule: extended application for testing high temperature volatile components of plastic raw material granule.

Extended application:

Carpet: used for testing the volatilization of carpet under high temperature.

Leather: used for testing the volatility of leather under high temperature conditions.

Sponge, rubber, EPE insulation materials: suitable for testing the high temperature volatility of sponge, rubber, EPE insulation materials.

Hernia lamp: suitable for the measurement of high temperature atomization of hernia lamp.

Adhesive products: suitable for testing the high temperature volatility of adhesive products.

4. Test principles

The sample is heated in a fogging cup and begins to evaporate. The volatile gas condenses on a glass plate or aluminum foil that has been cooled by the cooling chamber. After the condensation process, take off the glass plate or aluminum foil, measure the atomization value or weight of the condensed components of the glass plate or aluminum foil, and compare with the data before the condensation, so as to obtain the atomization and volatilization characteristics of the sample.

The equipment complies with a number of national and international standards: ISO 6452, DIN 75201, SAE J1756, QB/T 2728, BS EN 14288, PV 3920, PV 3015, es-x83231, NES M0161, D45 1727, GM 9305P, TSM 0503G

Three methods of measurement

Gloss method: the gassy value of the sample can be obtained by comparing and calculating the gloss value of the glass plate before and after condensation.

Fogging method: the fogging value of the sample can be obtained by comparing and calculating the fogging value of the glass plate before and after the glass plate condensation.

Gravimetric method: the sample is condensed on the low-temperature aluminum foil by the gas vaporized by heating in the fogging cup. By weighing the weight change of the aluminum foil before and after condensation, the weight of the atomized -- condensed sample can be obtained.

5. Operation steps:

▲ sample preparation

▲ open high and low temperature bath and reach the set temperature

Clean fog cup and fog glass plate

▲ placing the sample

▲ place foggy glass plate or aluminum foil

▲ place the cooling chamber

▲ the two grooves maintain the set temperature and operate normally until the time required by the test

▲ remove the glass plate or aluminum foil and place it until the specified time

▲ measure the gloss, fog or weight of aluminum foil

▲ compare the data and come up with the final results
