In the process of our trivalent chrome black zinc passivation, often because of the poor impurity resistance of the working solution, the passivation film of the workpiece is not black enough or the corrosion resistance of the coating is poor, resulting in poor quality of the coating of the workpiece and low productivity. Today we will introduce a trivalent black zinc passivator with high salt spray resistance.
Guangdong Bigely Technology Co., Ltd. is a trivalent chrome black zinc passivator manufacturer, which was founded in 2003. Bigely trivalent chrome black zinc passivator BZ-216 is specially developed for the galvanizing process, which has these 5 features:
1, it is formulated with imported raw materials, high purity with few impurities, stable tank liquid, low failure rate; high concentration of more than 20% higher than the counterparts, the dosage is provincial, more durable, lower production costs.
2, it is completely free of hexavalent chromium, the product is in line with the EU RoHS environmental requirements, just a simple impregnation, you can get a uniform and dense bright black passivation film.
3, the impurity resistance of the working solution is excellent, can be resistant to zinc impurities of more than 10g / L, iron impurities of more than 100ppm, long service life of the plating solution, and save production costs.
4, the workpiece corrosion resistance is good, neutral salt spray test produces white rust time greater than 72 hours, with sealer used together with better results.
5, a wide range of applications, BZ-216 can be widely used in electro-acoustic, auto parts, aviation, shipping, military, sanitary ware and other industries, suitable for a variety of different types of automatic production lines galvanized black passivation process production.
