2种新型防霉剂对刨花板的防霉性能
Mould-resistance of two new preservatives on particleboard
摘要
Abstract
Two preservatives: 1) a water-based colorless fungicide based on organic fungicides (OFP) and 2) a compound of chitosan metal complex/organic fungicides (CCP), were applied in two different ways (treating flakes or treating the finished board) to protect particleboard from three mould fungi: Penicillium citrinum, Trichoderma viride, and Aspergillus niger. Mould-resistance, internal bonding strength, and thickness swelling of the particleboard treated with the two preservatives were tested. Results showed that particleboard treated with OFP resisted P. citrinum and T. viride effectively having an infection value between 1 and 2 after one month of testing. However, with 10 g·kg-1 of OFP treating flakes before glueing and hot-pressing, resistance to A. niger was higher. Meanwhile, particleboard manufactured from CCP treated flakes resisted the three test fungi more effectively than the finished board treated with CCP. The internal bond strength of particleboards manufactured by CCP treated flakes were almost the same or slightly higher than the controls,whereas the OFP treated flakes were lower. Thickness swelling with CCP treatments after boiling 2 and 24 hours was less than the controls, whereas OFP was higher. [Ch, 6 fig. 2 tab. 15 ref.]关键词
