Influencing factors analysis of formaldehyde emission from GluBam sheet by climate chamber test
胶合竹材GluBam甲醛释放影响因素的气候箱实验与分析

GluBam is the main structural material used in modern bamboo buildings and its formaldehyde emission is important effect on the environmental performance and the acceptability during development. In this paper, the formaldehyde concentration released from GluBam sheet under different environmental conditions such as temperature, humidity and edge treatment were tested using 1 m3 climate chamber. A analysis method based on a first-order decay model was presented for estimating formaldehyde emission. The results show that the peak values of formaldehyde emission under all testing conditions are all lower than the limited value of 0.12 mg/m3 according to Chinese standard. Initial formaldehyde emission factor E0 and decay rate constant k in analysis model can estimate the released characters of formaldehyde. The formaldehyde emission increases with temperature and humidity increasing. The treatment of edge sealed can decrease releasing rate and amount of formaldehyde from GluBam sheet effectively.
