WXD钝化配方是一种使锌层表面产生高耐蚀性的新型低铬化学钝化配方,它不但为镀锌带钢,而且为镀锌零、部、构件等延长使用寿命提供了前景。各种镀锌件特别是大型部件钝化时间较长,钝化后需要水洗。在这种情况下应用WXD配方,选取怎
The WXD passivation formulation is a new, low chromium chemical passivation formulation that provides high corrosion resistance on the zinc layer surface and offers the prospect of not only galvanized steel but also extended service life for zinc-plated zero, parts and components. A variety of galvanized parts, especially large parts passivation longer, after passivation need to wash. In this case the application of WXD recipe, choose how
