A Study Regarding the Diminutive Effect of Emission of Indoor Air Pollutant (HCHO, TVOC) from After-Treatment Materials such as Ceramic and Catalyst

Abstract:

1) Upon comparing Ceramic products, which have been made into samples by the exactly same construction method as prefabbed wall of apartment, with the existing products, it is revealed that there would beno diminution effect on Pollutants like TVOC and HCHO. On the contrary, from the Ceramic applied prefab-wall, some pollutants, which were not seen from normal wall-panel, had been emitted additionally. 2) When we spreaded seven kinds of catalyst products on the surface of samples of MDF furniture and tested, two of those applied samples showed stronger tendency regarding the TVOC and HCHO emission than unapplied samples. Consequently, it is clarified that there's no effect of eliminating the pollutants like TVOC and HCHO from the application of catalysts as well as ceramic. In this regard, when we consider all the results collectively which were earned from these analysises up to now, using indiscreet after-treatment materials in residential place should be applied only after prudent examination.
