戊唑醇处理木质材料的防腐性及抗流失性研究

Decay and leaching resistance of wood and wood-based panels treated with tebuconazole

对经过超临界CO2流体携带戊唑醇防腐剂处理后的杉木、马尾松、中密度纤维板和刨花板的防腐性及戊唑醇防腐剂的抗流失性进行测定。结果表明,杉木、马尾松、中密度纤维板和刨花板经戊唑醇处理后,防腐能力都得到了较大提高,在绵腐卧孔菌或彩绒革盖菌的腐蚀下,杉木、马尾松的质量损失率降到10%以下;中密度纤维板、刨花板的质量损失率降到5%以下;戊唑醇防腐剂的抗流失性较好。

The decay and leaching resistance of Chinese fir, masson′s pine, medium density fiberboard and particleboard treated with tebuconazole by supercritical CO2 impregnation were measured. The results showed that the decay resistance of samples treated with tebuconazole was improved. After the samples treated with tebuconazole have been exposed white rot （Polyporus versicolor Fr.） or brown rot （Poria placenta Fr.） for twelve weeks, the loss weight of Chinese fir and that of masson′s pine were decreased to below 10%, the loss weight of medium density fiberboard and that of particleboard were decreased to below 5%; The leaching resistance of tebuconazole in samples was good.
