2种硼基防霉剂对慈竹重组材性能的影响

Effects of two kinds of boronbased fungicides on the properties of Bambusa emeiensis bamboo scrimber.

摘要: 以慈竹为原料，酚醛树脂（PF）为胶黏剂，硼酸锌（ZB）、硼硼合剂（SBX）为防霉剂，五氯酚钠（NaPCP）为对照药剂制备慈竹重组材，研究添加ZB和SBX对重组竹的物理力学性能及防霉性能的影响。结果表明：ZB和SBX对蓝变菌的防治效力很差。ZB和SBX的添加会削弱板材的物理力学性能，但防霉性能显著提高。研究范围内，这2种药剂的防霉变合理使用量分别为0.70%（ZB）和0.49%（SBX）。

Abstract: This study investigated the effects of zinc borate（ZB）and sodiumborate/boric acid（SBX）on the physical，mechanical and moldresistant properties of bamboo scrimber bonded with PF, and NaPCP was taken as the control. The results showed that the effects of ZB and SBX on the blue stainresistant efficacy were very poor. Adding ZB and SBX would undermine the physical and mechanical properties of bamboo scrimber, but highly improve moldresistant performances of the panels. The reasonable loading levels preventing mildew for ZB and SBX were 0.70% and 0.49%，respectively.
