Car interior material atomization test | car component atomization performance test

1. Introduction to the atomization performance test

atomization refers to the condensation phenomenon formed on the glass, especially the organic matter and vaporization substances from the internal plastic decoration of the car, especially refers On the windshield. When the lighting is not good, the atomization-coagulation may affect the degree of vision of the windshield. In addition, these harmful substances will also make people unknowingly poisoning. Must -check items.

Suitable for non -metallic fogging test instruments for vehicle non -metallic fog fog, such as top lining, floor pads, luggage compartment pads, masks, brackets, handlebars, leather decorations, steering wheels and seat belts and other non -metal materials in non -metal materials in non -metal materials. The evaluation of the performance of the volatile component at high temperature can also be used for the determination of the high temperature atomization phenomenon of the high temperature light of the front of the car.

According to the standard:

DIN 75201 (Determination of the material atomization performance of the material used in the internal equipment of the car)

ISO 6452 Duxiality measurement)

SAE J1756 (test method of foggy characteristics of car interior parts)

By conducting atomization tests on the interior decorative materials of the car, the control of volatile substances in these materials can be effectively reduced to effectively reduce the environmental pollution in the car. An important means of product quality.

2. Method of atomization test test

There are many in the country and domestic types of auto interior materials. These standards involve three test methods: That is, the luster method, the weight method, and the misty method.

3. The principle of atomization test test

The sample was heated in the fog cup and began to volatilize. 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.

Three measurement methods:

Glossness method: The gas condensed on the low -temperature glass plate by the sample in the foggy cup, the luster of the gloss before and after the glass plate condenses The degree value is compared and calculated, and the fog value of the sample can be obtained.

Misty method: The gas condensed on the low -temperature glass plate by the sample in the foggy cup, which is compared and calculated by comparing the fog value before and after the glass plate condensation. It is fog.

Heavy quantity method: The gas condensed on the low -temperature aluminum foil that the sample was heated in the foggy cup, by weighing the weight change before and after weighing aluminum foil, you can get a trial.Sample fog -the weight of condensate.

4. The structure and technical indicators of atomization test testing equipment

Mainly from high temperature constant temperature tank, low temperature constant temperature tank, cooling disk, fog cup, fog glass board , Measuremeter, sampler and accessories, which can complete the test process of sampling, heating, condensation, and testing.

The technical indicators of atomization test equipment are as follows:

High temperature tank temperature range: room temperature ~ 150 ℃ (room temperature ~ 280 ℃ separately)
High temperature tank temperature control precision: plusmn;: plusmn; 0.1 ℃ (150 ℃)

Low temperature tank temperature range: 0 ～ 100 ℃

Low temperature groove temperature control precision: plusmn; 0.1 ℃

High temperature tank shape size: 670 mm (670 mm ( L) times; 490 mm (b) times; 540 mm (h)

Low -temperature groove shape size: 400 mm (L) times; 220 mm (b) times; 520 mm (h)

High temperature tank Net weight: 32kg (excluding thermal conductivity)

Low -temperature tank net weight: 15kg (excluding thermal conductivity)

Power: AC 220V 50Hz

Test applicable standard：

DIN 75201、ISO 6452、SAE J1756、QB/T 2728、BS EN 14288、 PV 3920、PV 3015、ES-X83231、NES M0161、D45 1727、GM 9305P、 Tsm 0503g
