【摘要】 人造板释放的有害挥发气体有500多种,其中,重要气体包括萜烯、乙醛、酮,苯和甲苯等。东北林业大学在国内率先研制出这种有机挥发气体采样舱,通过一个小的不锈钢环境舱,对复合材料如地板、墙板、涂料和家具制作材料释放的有机挥发气体浓度采样,并制定出相应的取样规程,初步研究实验表明:该采样仓各项性能稳定,采集的样品能够真实反映代表性气体的品种和数量,取样效果明显,该装置具有较高实用价值。图2表1参7。更多还原

【Abstract】 Terpenes, aldehydes, ketones, benzene, and toluene are the important volatile organic compounds (VOCs) emitted from wood composites. A sampling apparatus of VOCs for wood composites was designed and manufactured by Northeast Forestry University in China. The concentration of VOCs derived from wood based materials, such as flooring, panel wall, finishing, and furniture can be sampled in a small stainless steel chambers. A protocol is also developed in this study to sample and measure the new and representative specimens. Preliminary research showed that the properties of the equipment have good stability. The sort and the amount of different components can be detected from it. The apparatus is practicable.更多还原
