摘要：
Emission of volatile organic compounds (VOCs) from medium density fibreboards (MDF) containing different proportions of softwoods (SW) and hardwoods (HW) was evaluated. The results reveal that decreasing the proportion of HW in MDF elevates the emission of terpenes and aliphatic aldehydes. The pulping method (TMP, CTMP) seems to have no significant influence on the emission of terpenes or aldehydes from MDF. On using the TMP process, the emission of acetic acid elevates remarkably with increasing the amount of HW in the boards. Compared with the TMP process, the CTMP process leads to a decrease of acetic acid emission at 408C with more than 15% at 35% HW content of the boards and 40% at 65% HW content.
