中文摘要: |
为了在玻璃微珠表面实施无钯活化化学镀镍,以醋酸镍和次亚磷酸钠的甲醇溶液为活化液研究了空心玻璃微珠表面化学镀镍的工艺。当每升甲醇中溶有醋酸镍和次亚磷酸钠各4009时,以20g/L的装载量,将玻璃微珠在其中浸泡20min,并在165℃下热氧化还原反应30min后施镀,将施镀前后的玻璃微珠分别用环境扫描电镜和X射线能量色散谱仪进行表观形貌和成分测试,结果表明,利用该工艺可在玻璃微珠表面形成均匀光滑、包覆完整的镍磷镀层。以此工艺代替胶态钯活化工艺,既可降低成本,又可降低对环境的污染。 |
英文摘要: |
In order to implement palladium-free activation electroless nickel plating on cenosphere surface, the technique for the cenosphere particles modified by electroless nickel plating activated by the methanol solution dissolving nickel-acetate and sodium-hypophosphite was investigated. The concentrations of nickel-acetate and sodium-hypophosphite were both 400g per liter methanol. Before electroless nickel plating, 20g cenosphere particles were soaked int0 1 liter activation solution for 20 minutes, heated and reacted for 30 minutes at 165 ℃ . The morphologies and the composition of original and modified cenosphere particles were characterized by environment scanning electron microscope and energy dispersive X ray spectroscopy, respectively. The results indicate that uniform and continuous Ni-P alloy coating is obtained on the cenosphere surfaces by this process. The technique can replace the palladium activation process to reduce not only the cost, but also the environment pollution. |
