Impact on the Indoor Environment of the Release and Diffusion of TVOC

摘要

The release of VOCs by architectural decorative material, furniture and indoor things for use is considered the main reason for indoor environment pollution. The polypropylene Styene-Butadiene Rubber (abbreviation SBR) is regarded as a TVOC release source. The control function of the mechanism mode is put forward according to the process of the TVOC under dry conditions within the room in this study. The function is made up of three parts: the diffusion transport function of VOCS in the material and the release transport function in the interface between air and material and the convention diffusion transport function of the TVOC in the air. The ventilation rate of the local research region was determined after analyzing the VOCS release and diffusion concentrations by using the CFD and VOCS release rates. The average concentration in the different baking temperature was compared. Effective dilution and ventilation methods should be further developed to shorten VOCS release time and reduce its indoor concentration.
