| 中文摘要: |
| 镀锌层蓝白色钝化膜耐腐蚀性差是电镀行业一个长期得不到解决的难题，六价铬盐蓝白色钝化膜是如此，三价铬盐蓝白色钝化膜也是如此；这是由于蓝白色钝化膜层太薄的缘故。为此，在增加蓝白色钝化膜的厚度方面进行了努力，终于研制成功了一种能获得较厚、具有高耐蚀性钝化膜的WX-3TC三价铬蓝白色钝化剂及其钝化工艺，盐雾试验出现白锈的时间可迭240h以上，从而解决了蓝白色钝化膜耐腐蚀性差的难题。 |
| 英文摘要: |
| Poor corrosion resistance of blue white passivating layer on zinc plated layer is a long-term problem which can not be settled in electroplating trade. The blue white passivating film of trivalent chromium is similar to that of hexavalent chromium. This is the reason that the blue white passivating film is too thin. So, in order to settle the problem, a kind of process to acquire compare thick passivating film, high corrosion resisting rCVX-3TC trivalent chromium blue white desensitizer and its means were successful obtained. The white rust appears after 240h in salt spray test, thus the poor corrosion resistance of blue white passivating film can be settled. |
