초록
In previous study, volatile organic compounds (VOCs) emission characteristics were highly affected by coating materials for wood finishing. Natural based coating materials showed that about 15~46% lower TVOC emission than typical products. In this study, long-term changes of VOCs emission characteristics from pine panel with three types of coating treatments were determined. Non-treated pine panel emitted 604.7 μg/m2⋅h of TVOC that contained 66% of NVOC (399.7 μg/m2⋅h) at 0 month. After 10 month, TVOC reduced 88% and 93% reduction on NVOC was observed. Natural oil and waterborne stain treated pine panel showed 61% and 77% lower TVOC, respectively, than non-treated pine panel. However, TVOC from finished pine panels showed higher TVOC emission than non-treated pine panel. All samples satisfied the VOC emission regulation (below 4,000 μg/m2⋅h) by Korean Ministry of Environment. Toluene emission regulation (below 80 μg/m2⋅h) was passed on all sample without varnish treated pine panel at 0 month. According to HB qualification standard for construction materials by Korea Air Cleaning Association (KACA), wood is not qualified to get the best tag due to high TVOC emission. At the 10 months, only non-treated pine panel could get the best tag of HB from KACA.
Abstract
In previous study, volatile organic compounds (VOCs) emission characteristics were highly affected by coating materials for wood finishing. Natural based coating materials showed that about 15~46% lower TVOC emission than typical products. In this study, long-term changes of VOCs emission characteristics from pine panel with three types of coating treatments were determined. Non-treated pine panel emitted 604.7 μg/m2⋅h of TVOC that contained 66% of NVOC (399.7 μg/m2⋅h) at 0 month. After 10 month, TVOC reduced 88% and 93% reduction on NVOC was observed. Natural oil and waterborne stain treated pine panel showed 61% and 77% lower TVOC, respectively, than non-treated pine panel. However, TVOC from finished pine panels showed higher TVOC emission than non-treated pine panel. All samples satisfied the VOC emission regulation (below 4,000 μg/m2⋅h) by Korean Ministry of Environment. Toluene emission regulation (below 80 μg/m2⋅h) was passed on all sample without varnish treated pine panel at 0 month. According to HB qualification standard for construction materials by Korea Air Cleaning Association (KACA), wood is not qualified to get the best tag due to high TVOC emission. At the 10 months, only non-treated pine panel could get the best tag of HB from KACA.
