摘 要
在本次实验前查阅文献了解磷化工艺各种类型的优缺点,而锌系性能优良是目前研究的主要方向,因此提出锌系磷酸盐处理作为本研究方向。实验确定磷化处理工艺的各种条件,温度为30—500C,PH值为2.8左右,促进剂为亚硝酸钠1.0g/L,添加剂为氟化钠1.0—1.5g/L。再通过正交实验确定中低温磷化配方:氧化锌为8.00g/L,磷酸为0.07mol/L,硝酸为0.06mol/L, ,硝酸镍为1.00g/L。

In this experiment to check the advantages and disadvantages of various types of literature to understand Linhua crafts, and the fine performance of zinc is the main thrust of the study, it is proposed zinc phosphate processing as the directions of research. Linhua processing techniques to identify the various experimental conditions, temperature 30-500C,PH value to 2.8% for agents to nitrite 1.0g/L, additives for entry 1.0-1.5g/L. Through the orthogonal set of experiments cryogenic Linhua formula : zinc oxide for 8.00g/L, phosphoric acid for 0.07mol/L, for 0.06mol/L nitric acid, and nitric acid to 1.00g/L nickel. Internet : Linhua, bluestone bit, feel sexual, orthogonal tests
