Description
技术领域
本发明属于金属表面处理技术领域，具体涉及一种热镀锌板用钝化液的制备方法。
背景技术
为了减少钢铁的腐蚀，通常将钢铁表面镀上一层金属锌，此类方法已经广泛的应用于机械、航空等领域。其腐蚀的机理包括两个方面，一方面是物理屏障保护，镀锌层在常温、干燥的空气中容易形成一层致密、坚固、耐蚀的碱式碳酸锌保护膜，阻隔了一些腐蚀介质入侵到铁基体表面与其发生腐蚀反应，从而使钢铁的腐蚀寿命有所延长；另一方面是阴极保护的原理，镀锌层覆盖在铁基体是阴极保护的作用，铁基体的腐蚀电位比金属锌的腐蚀电位要高，所以当腐蚀发生时，铁基体作为阴极得到了保护，而金属锌却作为阳极被优先溶解。镀锌方法有很多，最常见的有热镀锌和电镀锌，热镀锌成本低廉、操作工艺简单、生产效率高，其适应性良好，能够在各种不同形状、大小的产品上施镀，使得热镀锌成为了使用最多的镀锌手段，热镀锌防护技术已经可以应用到建筑、交通防护和磨具等方面，随着近年来热镀锌钢铁在通信、采矿、造船等方向应用的拓展，热镀锌技术有着广阔的应用前景。
镀锌是一种提高钢铁抗腐蚀能力的常用手段，但是锌层在潮湿的空气中容易被腐蚀形成白锈，从而失去防护作用，为了进一步提高镀锌层的耐蚀性，通常在镀锌层进行钝化处理，不仅提高了其表面质量，也延长了钢铁镀锌层的使用寿命。镀锌钝化板广泛应用于家电行业及汽车等领域，随着科学的进步和环保水平的提高，高污染、致癌性的传统铬酸盐钝化已经逐步被淘汰，开发新型、低污染、无毒的钝化技术是科研工作者的研究热点。
