氨溶季铵铜添加量和酚醛树脂施胶量对定向刨花板性能的影响
The Influence of Amine Copper Quant Addition Amount and Phenol Formaldehyde Resin Content on the Properties of Oriented Strand Board
摘要
Abstract
In this study,oriented strand board(OSB)was made by adding amine copper quant(ACQ)and phenol formaldehyde resin(PF)in order to investigate the effects of ACQ additions(2,4,and 6 kg/m3)and PF additions(8%and 10%)on the physical,mechanical,and preservative properties of OSB.The study revealed that the physical and mechanical properties of the OSBs achieved the requirements of OSB/4 class boards in the GB/T 41715-2022"Oriented Strand Board",although these property values decreased as the amount of preservative increased.Meanwhile,the addition of ACQ preservative improved the preservative properties of OSB.When the PF and ACQ content was at 10%and 6 kg/m3 respectively,the average mass loss rate of the samples after 12 weeks of infection by brown rot fungus was finally reduced to 1.72%,which was only 22.7%of the control samples.The results of average mass loss rate and morphological analyses indicated that the physical encapsulation of PF and the synergism of ACQ enhanced the preservative properties of the samples.This study added data to enhance the understanding of the physical,mechanical,and preservative properties of OSB,specifically regarding improvements in durability and long-lasting utilization.关键词
