Characteristics of TVOC, Aldehydes and Ketones Emitted from Fiber Hot-Pressing in Manufacturing of MDF made from Poplar and Pine

This study, by means of GC-MS and HPLC, investigated the characteristics of volatile organic compounds (VOCs) released from fiber hot-pressing in a medium density fiberboard (MDF) production line with a production capacity of 80,000 m3/a. The quantity of total volatile organic compounds (TVOC), aldehydes and ketones were calculated. The results showed that the concentration of TVOC reached 1.8940 mg/m3. The main components include terpenes, acrolein and acetone, benzenes series and saturated hydrocarbons. The concentration of the mixture of aldehydes and ketones was 5.1136 mg/m3.
