A. Introduction of test chamber
Benzene and toluene in formaldehyde and VOC are strong carcinogens recognized by WHO.
Long-term exposure to pollutants exceeding the standard concentration will seriously endanger people's health.
Testing and limiting the amount of pollutants released will help to improve product quality and protect people's health.
Wood products, furniture, floors, carpets, footwear products, building decoration materials, automotive interiors and other products in contact with the human body will volatilize VOC (volatile organic compounds), formaldehyde and other harmful substances to the human body, especially for products placed in intensive, space-closed indoor, car, the concentration will be accumulated,After accumulation, the concentration will be higher and the harm to human health will be greater.
This test chamber is an instrument used to simulate the release of VOC (formaldehyde) from products near people's living environment. It is used to test and evaluate the release of harmful substances in furniture, building materials, automobile interior and other products.
This test chamber provides a clean enclosed space (very low background concentration), does not appear liquid water (to prevent formaldehyde and other components easily absorbed by water to be measured), while controlling the temperature, humidity, wind speed, relative pressure, ventilation rate in the warehouse, which is used to simulate the pollutant release process of products in the environment similar to people's living environment. Through monitoring the concentration of pollutants in the warehouse, the release amount is determined to evaluate the environmental protection level of the products.
It is mainly used to detect the amount of formaldehyde and VOC released from interior decoration materials, decoration and decoration materials, wood-based panels, wood products, and other products. According to indoor pollutant data or prediction model, the indoor air quality is evaluated by comprehensive environmental indicators
