摘要
由于环保问题,传统的含磷预膜剂被限用.本文研制出一种无磷高效的预膜剂,在常温下可进行预膜,硫酸铜溶液点滴测评,远大于HG/T 3778-2005规定的10 s,而且预膜废水不含磷,无需排放置换,可以直接转入正常的生产运行.
Abstract
Due to environmental problems,the traditional phosphorous pre-film agent is limited.A phosphorus-free and efficient pre-film agent has been developed in this paper.It can be used for pre-film at room temperature,and the drop test of copper sulfate solution is much longer than the 10 s stipulated.Moreover,the pre-film wastewater did not contain phosphorus and can be directly transferred to normal production operation without discharge and replacement.
