Abstract: The main factors affecting the change of indoor formaldehyde concentration are analyzed through the actual measurement of formaldehyde concentration, furniture loading rates, and environmental factors for the newly residential buildings which renovated less than three months. On this basis, the release process of formaldehyde in wood-based panel is studied by using the imitation home environment test chamber, and the relationship is analyzed between the wood-based panel exposed rates and release concentration. The formaldehyde release law curve of wood-based panel is derived, which provides a theoretical basis for the selection of standard pollutants and the initial concentration of pollution in the evaluation of formaldehyde purification performance of air cleaner in the home environment.
