Description

一种铸造工件防腐处理工艺
技术领域
本发明涉及金属材料防腐技术领域，具体涉及一种铸造工件防腐处理工艺。
背景技术
我国机械制造加工业的飞速发展，特别是我国加入WTO以后，我国已成为国际机械加工的重要基地，因此，对组成机械设备的各类零部件的材质、功能性、防腐性甚至装饰性，都提出了更高的要求。原来在铸件上刷油漆的方法已不受欢迎，油漆会掩盖铸件裂痕、孔隙，而以下介绍的工艺必将受到欢迎。铸件由于制造工艺的特殊性，铸件表面容易锈蚀，生锈后很难处理，如不引起重视，不但工件的防锈蚀能力较差，装饰性也不好，对此很多企业在对铸件提出较高的耐蚀性要求的同时，根据铸件不同的工作条件，要求对铸件(铸铁、铸钢)进行常温发黑、磷化处理和其它特殊的防锈处理。
发明内容
针对现有技术的不足，本发明提供一种铸造工件防腐处理工艺，克服了现有技术的不足，不仅起到了工序间的防锈，也消除了以后除油的麻烦，同时也保持了工件干净，方便存放，只是在使用前工件需无油无锈，防锈期结束后，如需清除防锈层，可用碱性水基清洗剂中温进行清洗，比较方便。
本发明所要解决的技术问题可以通过以下技术方案来是实现:
一种铸造工件防腐处理工艺，第一步除锈活化，除锈通过滚光、喷砂、抛光、打磨的方式将其表面处理干净之至光泽出现，再经水清洗；
第二步铸件在20-25℃防腐处理溶液中处理5-15分钟，水洗后不经酸洗直接进入发黑槽，实现无酸洗常温发黑，有利于改善环境和提高工效；
第三步，在常温发黑件从槽液中取出后，其表面层的化学反应并未得到最后完成，在空气中氧的作用下放置24小时；
第四步，然后第三步处理完的工件通过用干净水浸泡或清洗在工件进行化学除油除锈前，先对工件进行清洗、浸泡；
第五步，经前处理后充分洗净后可直接镀黑镍，也可镀白镍后再镀黑镍，颜色均匀。
所述的发黑剂加5-6倍水稀释成工作液，PH值为2-2.5，处理的时间一般在1-3分钟将工件拌动几次，视工件表面黑膜层均匀即可。
所述的防腐处理溶液由酸式磷酸锰20-30份、磷酸二氢锌20-30份、氟锆酸钾1-3份、植酸1-3份、柠檬酸3-5份、乳化剂0.5-1份、乙烯基硅烷1-2份、环氧基硅烷2-4份和适量磷化促进剂组成。
所述的酸式磷酸锰25份、磷酸二氢锌25份、氟锆酸钾2份、植酸2份、柠檬酸4份、乳化剂0.8份、乙烯基硅烷1.5份、环氧基硅烷3份。
所述的磷化促进剂为氯酸盐、过氧化氢或有机硝基化合物。
与现有技术相比，本发明的有益效果为：
本发明不仅起到了工序间的防锈，也消除了以后除油的麻烦，同时也保持了工件干净，方便存放，只是在使用前工件需无油无锈，防锈期结束后，如需清除防锈层，可用碱性水基清洗剂中温进行清洗，比较方便。
