棉纤维表面化学镀镍工艺的研究

Study of Electroless Nickel Plating on the Surface of Cotton Fiber

实验研究了棉纤维化学镀镍的操作方法、工艺条件,讨论了各种因素对化学镀层的影响,实验了化学镀层与棉纤维的结合力及镀层的耐腐蚀性,确定了棉纤维化学镀镍的工艺流程和最佳实验控制条件,实验结果表明,棉纤维经过预处理及敏化、活化处理后,化学镀镍溶液的pH值控制在8.5,镀镍温度在90°C,反应时间40min,可以得到较好棉纤维化学镀层。

The operating methods, the process and the influence of several factors on nickel -plating on the surface of cotton fiber were studied. Then it was tested the combination strength between chemical coating and cotton fiber and determined the process and the optimum conditions finally. The quality of electroless nickel- plating was good, when the cotton fibers were pretreated, sensitized, and activated, the pH = 8.5, the reaction temperature was 90℃ and the reaction time was 40 rain.
