阅读说明：本技术 钝化剂、金属工件及其表面处理方法 (Passivating agent, metal workpiece and surface treatment method thereof ) 是由 刘国平 于 2017-07-03 设计创作，主要内容包括：一种钝化剂、金属工件及其表面处理方法，以1000重量份计，该钝化剂包括按照重量份数配比的下列成分：5?20份硝酸铬，1?5份硫酸钴，1?5份磷酸二氢钾，1?5份双氧水，2?5份钼酸铵，l?3份硫脲，0.5?4份氯化镁和余量的蒸馏水。经钝化的镀锌板在镀层表面形成黑色的坚固保护膜，耐蚀性，抗氧化性，装饰性等性能都大大增强，可广泛应用于各种金属镀件，尤其对镀锌层钝化更佳。(The passivator, a metal workpiece and a surface treatment method thereof are characterized in that the passivator comprises the following components in parts by weight, based on 1000 parts by weight: 5-20 parts of chromium nitrate, 1-5 parts of cobalt sulfate, 1-5 parts of monopotassium phosphate, 1-5 parts of hydrogen peroxide, 2-5 parts of ammonium molybdate, l-3 parts of thiourea, 0.5-4 parts of magnesium chloride and the balance of distilled water. The passivated galvanized sheet forms a black firm protective film on the surface of the plating layer, the performances of corrosion resistance, oxidation resistance, decoration and the like are greatly enhanced, and the passivated galvanized sheet can be widely applied to various metal plated pieces, and is particularly better for passivating the galvanized layer.)
