MODIFIED EPOXY COATING BY ADDING QUATERNARY AMMONIUM COMPOUND AND ITS PROPERTIES IN INHIBITING ALGAL ADHESION AND GROWTH

  • 摘要: 针对污水处理厂污水处理构筑物藻类生长与黏附现象严重的问题,采用共混方法制备季铵盐(QAC)/环氧树脂复合涂层,并探究QAC投加量对复合涂层的性质和抑藻性能的影响。结果表明:QAC与环氧树脂涂料成功复合,改性涂层表面的季铵基团(R4N+)数量随QAC投加量增大而增加;QAC改性对涂层的疏水性、耐水性不产生明显影响。但与环氧树脂涂层相比,随QAC浓度的增加,复合涂层表面的Zeta电位向正电性偏移,粗糙度略微减小;以小球藻(Chlorella vulgaris)作为模型藻类进行的涂层抑藻性能研究表明,QAC/环氧树脂复合涂层表面黏附的小球藻数目明显少于环氧树脂涂层,且QAC投加量越多,涂层抗藻污染性能越好。
