一种简便实用的钢铁防锈擦涂磷化液的研制

Study on a New Type Rubbing and Rust Preventive Phosphating Solution for Steel and Iron

为了对机电设备及零部件的局部磷化,研制了一种用擦涂方法进行磷化的磷化液,分析讨论了复合促进剂对磷化成膜速度和磷化膜性能的影响。该磷化液游离酸度稳定、常温下操作、工艺简单。磷化膜层致密耐蚀且厚度均匀、可调,外观呈银白或银灰色。可用作耐磨、耐蚀膜层,也可用作有机涂层的基底。

To phosphate for parts of equipment and component, a type of rubbing and rust preventive phosphating solution was studied. Such problem as how to improve phosphating velocity and corrosion resistance were synchronously discussed. The free acidity of liquid in phosphating at normal atmospheric temperature is stable, and operating technology is simple. Phosphating film is fine and close and the thickness of film can be changed, the color of film is silver white or silver grey. The film can be used as wear resisting and corrosion resisting or base of organic coat.
