一、前言简化工艺流程,降低操作温度,力求磷化膜薄而致密,与油漆配合具有高附着力和耐蚀性,是当前钢铁制品漆前磷化处理工艺发展的总趋势。本文作者为谋求实现这一目标,拟研制“低温多功能磷化液”。二、实验与结果 First, the preface Simplify the process, reduce the operating temperature, and strive to thin and dense phosphate film, with the paint with high adhesion and corrosion resistance, is the current steel products lacquer phosphating process development trend. In order to pursue this goal, the author intends to develop “low-temperature multi-functional phosphating solution”. Second, the experiment and results
