Mr. Luo is engaged in galvanizing processing, and his clients mostly make small metal parts. A large part of these parts require galvanizing color passivation, and the appearance requires hexavalent chromium color passivation. However, facing the constraints of environmental policies, the use of hexavalent chromium color passivators has been banned, and Mr. Luo has to use trivalent chromium color passivators as well.
However, after using trivalent chromium color passivator, Mr. Luo's product appearance always fails to meet the customer's requirements. Some have a significant difference in appearance and cannot achieve the color of yellow with a hint of red; Some workpieces have poor corrosion resistance, and changing them cannot meet the performance requirements of the workpiece; Some of the solutions are unstable and have poor tolerance for impurities. The passivation solution needs to be re slotted within a few days, resulting in high usage costs. For this reason, Mr. Luo was very distressed and had to switch to several trivalent chromium color passivators during this period. The only thing he could barely accept was this light yellow appearance.
Until one day, Mr. Luo was drinking tea with a friend when he saw that his friend was using Bigely's trivalent chromium color passivator BZ-207. It not only had a similar appearance to hexavalent chromium, but also passed various performance tests on the workpiece. The tank solution was very stable, with high tolerance for impurities and a long service life, which could save production costs.
Mr. Luo was very excited and immediately contacted Bigely's engineer. At the beginning, Mr. Luo took samples of trivalent chromium color passivator BZ-207 for testing, and the results showed that the appearance and performance of the workpiece could meet the customer's needs. So Mr. Luo directly slotted for production and found that this product was really good. The operation range of passivation solution is wide, the appearance color of the workpiece is very uniform, and maintenance and management are simple; Moreover, it has a high tolerance for impurities, and iron impurities exceeding 100ppm have no impact on production; Also, the corrosion resistance of the workpiece after passivation is excellent, with a neutral salt spray test lasting over 120 hours. Since using Bigely's trivalent chromium color passivator BZ-207, Mr. Luo's customers have been very satisfied with the appearance and performance of the product.
So, choosing a suitable trivalent chromium color passivator is very important. The product has good quality, can meet the requirements of production technology, and can also meet the customer's needs for appearance and performance. Bigley's trivalent chromium color passivator BZ-207 is such a product.
