高效液相色谱测定多菌灵及三唑处理材的流失性能

Carbendazim and Triazole Leachability Evaluation in Treated Wood

为改善竹木制品的防霉防变色性能,及提高处理药剂的抗流失性,采用多菌灵(CBZ)、多菌灵与三唑化合物的混合溶液,分别处理马尾松试材后,在试材表面涂刷不同的疏水剂。采用高效液相色谱法,测定处理材中CBZ、三唑化合物的流失性能。结果表明,涂刷疏水剂后,处理材中CBZ、三唑的固着率显著提高,其中水性清漆的改善效果最好。

Pine （Pinus massoniana） samples were treated with carbendazim （CBZ）, tebuconazole （TEB） and propiconazole （PPZ）, and then brushed with hydrophobic agents for preventing mold and sap stain. CBZ, TEB and PPZ leachability from the samples was tested using high performance liquid chromatography （HPLC）. The results indicated that the CBZ, TEB and PPZ fixation rate improved after brushing with a hydrophobic agent. There was a significant hydrophobic agent concentration effect on the carbendazim fixation rate in the samples.
