常温磷化经常出现磷化膜泛黄、挂灰和耐蚀性差的缺点。通过对常温磷化原理,以及对冷轧钢薄板常温磷化生产流程的应用分析,推荐一种国产常温磷化剂,可以获得均匀、细致、密实的磷化膜,逐步替代传统的中高温磷化工艺。 Phosphating room temperature phosphating often yellowing, hanging ash and poor corrosion resistance shortcomings. Through the principle of normal temperature phosphating and the application analysis of the cold phosphating production process at room temperature, we propose a home-made phosphating agent at room temperature to obtain a uniform, detailed and dense phosphating film and gradually replace the traditional medium- and high-temperature phosphorus Chemical process.
