摘要

以三层结构的沙柳重组材为基材,用单板-酚醛树脂浸渍纸或浸渍酚醛树脂的硬质纤维板为覆面材料,制备沙柳重组复合混凝土模板。试验结果表明,在施胶量12%、热压温度160℃、热压时间0.9min/mm的条件下制备基材,经过贴面处理,2种结构的复合板的耐水性比基材显著增强,纵向静曲强度和弹性模量降低,横向静曲强度和弹性模量提高,主要性能接近混凝土模板相关标准要求。

Abstract

To explore new opportunities of utilizing salix （of the willow family） wood, the authors made salix-based composite panels, overlaid with PF impregnated paper faced veneer or PF impregnated fiberboard, for a concrete molding application. They investigated the effect of processing conditions on the composite’s performance. The results showed that the optimal process conditions were: 12% adhesive and 160 ℃ press temperature for 0.9 min/mm panel thickness. The salix panels produced under these optimal conditions had performance similar to the specifications of comparable products.
