摘  要：
为拓展单板层积材(LVL)的应用领域,延长其使用寿命,通过季铵铜(ACQ)和铜唑(Cu Az)常压浸渍单板,研制防腐马尾松单板层积材(LVL),考察了防腐剂种类和载药量对LVL耐腐及物理力学性能的影响。结果表明:ACQ和Cu Az预处理单板显著提高了马尾松LVL耐腐性,处理材达到强耐腐等级;处理材的弹性模量和静曲强度达到GB/T 20241—2006标准规定的结构用LVL中120E至160E级别要求,剪切强度达到50V-43H级别要求,浸渍剥离率仅为0.1%~0.8%。与未处理材相比,处理材的弹性模量略有增加,剪切强度及部分处理材的静曲强度有所下降;但处理材之间、处理材与对照材之间的力学性能均无显著差异。研究表明,ACQ和Cu Az常压浸渍预处理单板是研制防腐马尾松LVL的一条有效途径。

摘  要：
To expand the application and extend the service life of laminated veneer lumber( LVL) products,this study focused on the development of preservative-treated masson pine LVL using the non-pressure veneer soaking treatment with alkaline copper quaternary( ACQ) and copper azole( Cu Az). The effects of veneer treatments with preservative types and loading levels on the decay resistance,physical and mechanical properties of LVL were investigated. The results demonstrated that the treatments significantly enhanced the decay resistance of LVL. The bending properties of treated LVL met the requirements of grade 120 E to 160 E,while the shear strength exceeded the specification of grade 50V-43 H according to the standard GB / T 20241—2006. All treated LVLs had low delamination rate ranging from 0. 1% to0. 8%. The statistical analysis showed that there were no significant differences in physical and mechanical properties among treated and untreated groups. The study suggested that ACQ and Cu Az pretreatment is a promising method to make masson pine LVL with strong decay resistance and required physical and mechanical properties.
