采用常温浸渍处理方式,研究了氨溶烷基铵铜(ACQ-D)防腐剂浸泡时间及处理浓度对沙柳沙障吸药量及失重率的影响,进而评价ACQ-D防腐剂对沙柳沙障的防腐性能。试验结果表明:沙柳沙障吸药量随浸泡时间的延长而增加,经24h和48h处理的吸药量差异不显著,不同浓度处理吸药量达到标准的浸泡时间不同;经防腐剂处理的沙柳沙障失重率明显小于对照,且失重率随防腐剂浓度的增加而减小;各处理沙柳沙障的耐腐性均达到耐腐的等级。 The effect of ACQ-D preservative soaking time and treatment concentration on salvage dose and weight loss rate of Salixes albopictus was studied by using immersion treatment at room temperature. Then the effects of ACQ-D preservatives on Salix psammophila Sand barrier corrosion performance. The results showed that salbutamol barrier absorption dose increased with the soaking time, the difference was not significant after 24h and 48h treatment, soaking time at different concentrations reached the standard; The weight loss rate of Salix psammophila was significantly lower than that of control, and the weight loss rate decreased with the increase of preservative concentration. The corrosion resistance of Salix psammophila reached to the level of decay resistance.
