为什么要用无铬钝化剂

         自改革开放以来,随着我国金属行业的快速发展,在金属制品的高精密发展中伴随着废水废气噪音的产生,其中大量生产废水排放造成了严重的水体污染,成为了环保局的重点检查行业。使得金属行业对于环保也越来越重视,金属部品为了获得更好的防腐蚀防变色性能,需进行钝化处理钝化处理后的工件在原有的基础上防腐蚀放变色的能力都大大增加。在传统的钝化处理中都离不开:铬酸盐钝化工艺,因为使用的六价铬是剧毒和致癌物质,对环境及人类健康危害严重,许多国家都已严令限制铬酸盐钝化工艺的使用,所以,新型无铬钝化剂产品的出现对于金属行业以及环境的保护中都有具有十分重要的意义。

      Since the reform and opening up, with the rapid development of China's metal industry, the high-precision development of metal products is accompanied by the generation of waste water and exhaust noise, in which a large number of wastewater discharges have caused serious water pollution, and become the key inspection industry of the Environmental Protection Bureau. As a result, the metal industry attaches more and more importance to environmental protection. In order to obtain better anti-corrosion and anti-discoloration performance, the ability of anti-corrosion and anti-discoloration of passivated parts on the original basis has been greatly increased. Chromate passivation process is indispensable in traditional passivation treatment, because hexavalent chromium is a highly toxic and carcinogenic substance, which is harmful to the environment and human health. Many countries have strictly restricted the use of chromate passivation process. Therefore, the emergence of new non-chromium passivator products for the metal industry and the environment. Protection is of great significance.

       新型无铬钝化剂同样具有传统六价铬钝化剂、三价铬钝化剂等钝化剂的防腐蚀抗氧化能力。环保无铬钝化剂因为不含“铬”,主要由锆、钛金属离子、成膜促进剂、稳定剂、pH调节剂组成。使金属表面获得均匀的无色透明的化学转化膜,具有防腐蚀性强,结合牢固,能够显著增强工件与涂层和油漆的结合力相比传统六价铬、三价铬钝化剂更具环保性能,无铬钝化剂符合新的环保法规也能在不断变换的客户需求中得到满足。 所以金属的制造中需要用到钝化处理的一定要用环保无铬钝化剂。

The new chromium-free passivator also has the anti-corrosion and anti-oxidation ability of traditional hexavalent chromium passivator and trivalent chromium passivator. Environmental chromium-free passivator is mainly composed of zirconium, titanium metal ions, film-forming accelerator, stabilizer and pH regulator because it does not contain "chromium". The uniform, colorless and transparent chemical conversion film on the metal surface has strong corrosion resistance and strong bonding. It can significantly enhance the bonding force between the workpiece and the coating and paint. Compared with the traditional hexavalent and trivalent chromium passivators, the chromium-free passivators have more environmental protection properties. The chromium-free passivators meet the new environmental protection regulations and can also meet the changing needs of customers. Satisfaction.Therefore, when passivation treatment is needed in metal manufacturing, environmental chromium-free passivator must be used.
