项目摘要

The glue-additive treatment method is considered to be a practical approach which colud be easily introduced to commercial plants engaged in particleboard and plywood production saving cost and energy. When particleboards were treated by adding insecticides and fungicides to the adhesive-glue, the treated boards resisted effectively against to the virulent termite species, and inhibit effectively the decay by both brown-rot and white-rot fungi. SEM observations of the fractures surfaces presented visible evidence on glue-line failures which were caused by the active fungal invasion onto the surfaces of wood particles. Incorporation of fungicides in the glue was considered to be more effective against fungal growth by existence of toxicants around glue-line as well as their better distribution into the wood particles.Incombustibility of laminated-veneer-lumber (LVL) was attained by mixing ammonium pentaborate to the adhesive and pressing with heat-cure, and the relationship beteween the fire-proofing properties and the distribution of the chemicals was evaluated by analysing the positions of boron with X-ray Photo-Electron Spectroscopy (XPS).The particleboards with high dimensional stability and biological resistance were also produced by spray with a mixture of low molecular-weight phenol-formaldehyde (PF) resin and high molecular-weight PF resin. The distribution of low molecular-weight PF resin was detected by XPS analysis of Br which was bonded to the resin.

胶水加ad的治疗方法被认为是一种实用方法，可以轻松地将其引入从事刨花板和胶合板生产节省成本和能源的商业植物中。当通过在粘合剂中添加杀虫剂和杀真菌剂来处理颗粒板时，经过处理的板有效地抵抗了对毒物质物种的有效抗性，并有效地抑制了棕-Rot和White-Rot真菌的衰减。对裂缝表面的SEM观察结果表达了可见的证据，这些证据是由活跃的真菌侵袭在木材颗粒表面上引起的。粘合剂中掺入胶水中的掺入胶水周围的毒物以及它们在木材颗粒中的分布更好。层压式贴面 - 亮伯（LVL）的固定性通过将含量五二化的含量与粘合剂和耐热性的分布混合而成，并与耐热的分布相结合，从而使木质镀膜液的固定性（LVL）获得了更好的分配。通过X射线光电子光谱法（XPS）分析硼的位置。具有高尺寸稳定性和生物耐药性的颗粒板也通过与低分子量苯酚 - 苯酚甲醛（PF）树脂和高分子 - 分子量PF PF Resin的混合物进行喷雾产生。通过将BR的XPS分析检测到与树脂的XPS分析一起检测到低分子量PF树脂的分布。
