The objective of this study was to find the Emission Characteristics of TVOC and Formaldehyde according to time lapse of 1day and 7 days inside chamber from different composite material specimens which are made with short-term and long-termretention period materials. Also, influences of chemical substance emission are analyzed according to raw material storage period,surface finishing method and retention period after forming. The test is performed with 8 complex material specimens whichhave different material compositions.The results show as follows; The formaldehyde emission rate was decreased according to the time elapsed for complexmaterial specimen with short retention period, but it was increased with a long retention period. This indicates that formingcondition and method dominate the degree and status of emission amount. The TVOC emission has mixed result of increase anddecrease by specimen according to elapsed time, but all of the long-term retention period specimen tend to decrease as elapsedtime. The result indicates that TVOC emission in complex material has strong influence from single material retention period. |
