Measurements of volatile organic compound (VOC) emissions from wood stains using an electronic balance

An emissions test method using an electronic balance was introduced to measure the TVOC emission rates of oil-based wood stains, with a detailed procedure for preparing test specimens. The emission characteristics of volatile organic compounds (VOCs) from an artificial wood stain and an oil-based commercial wood stain were determined. Results show that VOC emissions from both stains include a surface evaporation and an internal diffusion sub-process. With regard to time, the entire emission period was divided into three periods: an initial evaporation-controlled period; a transition period; and an internal diffusion-controlled period.
