Application

The auto interiors VOC emission test chamber can provide a standard test environment (such as specified temperature, relative humidity, air exchange rate and airflow rate, VOC) or simulate a real indoor environment to test the release rate and release properties of pollutants from various interior materials and products. From the test results, users will
Determine the impact of environmental variables on material and products release rates and release characteristics.
Classify the materials and products grade according to their release characteristics.
Develop, verify and predict models of indoor air pollution.
Evaluate indoor air quality (IAQ) according to indoor pollutant data or predicted model.

Test principle
1.Air is compressed by air compressor, and the solid particles, formaldehyde, volatile organic compounds in the air are removed. Then the purified air is released into the test chamber.
2.The climate box adopts a jacket. The temperature of the test chamber is indirectly adjusted through controlling the temperature of jacket.
3.Dew point method is applied to adjust humidity of the climate chamber and humidity inside the test chamber. The method is simple and effective.

Technical advantage
The coated stainless steel inner wall improves the adsorption capacity of VOC substances with high boiling point and polar compounds. The recovery of tetradecane, 4 phenyl cyclohexene is more than 80%.

The patent is about how to deal with the connection surface between VOC emission chamber and the testing object. The technology helps to reduce the surface adhesive force, largely reducing VOC’s adhesiveness on chamber’s interior wall. In this way, the testing result of samples stored in the sampling bag is more close to the result of testing object in chamber, and the testing precision of emission chamber is largely improved.
