Block Effect of Overlaid Materials on the Emission of Perceived Air Pollutants from Covered Adhesives

Abstract

The block effects of overlaid building materials on emission of perceived air pollutants from covered adhesives were studied. A carpet and a wallpaper were used as solid materials. Box-sized small chambers were prepared to supply constant air to the sample of specimen. Untrained panel evaluated the perceived air pollution from the single materials (solid material itself and adhesive itself) and combinations of the overlaid solid material and the covered adhesive. The odor intensity of the pollutants from the combination of the solid material and the adhesive was lower than the sum of the odor intensity from the single material. The overlaid solid materials might have blocked the emission of the air pollutants from the covered adhesive. It was found that the block effect on perceived air pollutants was greater than that on TVOC emission.
