竹材铜唑防腐剂处理工艺及力学性能研究

摘要

以竹材为试验材料．采用新型水溶性铜唑（CopperAzole，即CuAz）防腐剂对其进行防腐处理．分析药剂质量分数、压力、前真空时间及加压时间对防腐处理效果的影响，比较处理前后对竹材力学性能的影响。研究结果表明，药剂质量分数是影响竹材防腐处理效果的显著因子；经铜唑防腐处理后，竹材的弹性模量（MOE）、顺纹抗拉强度和抗压强度无显著变化，抗弯强度（MOR）稍有降低。%In this study, CuAz preservative was used to treat bamboo by means of vacuum-pressure impregnation. The effects of preservative concentration, pressure, pre-vacuum time and press time on bamboo were analyzed, and the mechanical properties of treated bamboo were determined. The results showed that preservative concentration was the most significant affection factors on treatment result of bamboo. In comparison with untreated samples, the modulus of elasticity (MOE), tensile strength and compressive strength of treated samples did not significantly changed. However, the modulus of rupture (MOR) was decreased slightly compared to untreated ones.
