在金属表面涂覆中,磷化处理是喷涂施工关键的一环,它可将带有油污、锈蚀的工件经过化学方法处理除净,生成一层磷化膜,喷涂后能与漆膜牢固的结合,提高其附着力。然而,磷化膜的质量又要靠严格的工艺指标来控制,要以准确、快速的化学分析数据来指导现场生产,本文专以目前国内常用的磷化工作液中起决定因素的项目,介绍其快速测定的化学分析法。
In the metal surface coating, phosphating is a key part of the spray construction, it can be contaminated with oil, rust the workpiece after the chemical treatment in addition to clean, generate a layer of phosphate film, after spraying and film firm Combination, improve its adhesion. However, the quality of the phosphating film has to be controlled by the strict process index. The accurate and rapid chemical analysis data should be used to guide the on-site production. This article is devoted to the project that currently plays a decisive role in the commonly used phosphating solution. Its rapid determination of chemical analysis.
