Mr. Dai is the boss of a zinc plating factory in Huizhou.Recently, a friend introduced the use of a color zinc passivator.However, the coloring of the workpiece is very slow during passivation, and it takes 120~150 seconds to get a reddish colored passivation film. Moreover, the corrosion resistance of the workpiece after passivation is poor, which seriously affects the production efficiency.So Mr. Dai wants to find a trivalent chromium zinc passivator with better performance.
One day, Mr. Dai saw Bigolly's trivalent chromium color zinc passivator BZ-207 through Internet search, so he inquired about the characteristics and operating parameters of this passivator in detail.After the engineer had a detailed understanding of Mr. Dai's production process, he recommended Mr. Dai to use this color zinc passivator BZ-207 and explained that:This passivating agent is prepared with imported raw materials. The workpiece can obtain light yellow, purple red, bright green and other color appearances (the same as hexavalent chromium passivation appearance) within 30~90 seconds. The passivating appearance of the workpiece can be adjusted according to customer needs, with good operability.
In addition, this trivalent chromium color zinc passivator has a high tolerance for impurities in the bath during production, and has strong resistance to metal impurities such as zinc, iron and copper, which can greatly reduce the treatment frequency of the bath.Moreover, this passivation agent has good corrosion resistance. When the thickness of the zinc coating is more than 8 microns, the neutral salt spray is more than 120 hours, and the passivation film is bright and uniform, and does not fade or discolor. It can meet the requirements for color passivation of various mechanical accessories and metal stampings.Mr. Dai learned about this color zinc passivator and compared the product effect diagram, and then decided to buy two barrels to try.
Under the guidance of the engineer, Mr. Dai has greatly improved the corrosion resistance of the workpiece after using this color zinc passivator BZ-207. After passivation, the workpiece can easily pass the 96 hour salt spray test;The appearance of the workpiece can be adjusted by itself, and the operability is better. The passivation time of the workpiece is greatly shortened, and the production efficiency can be increased by 40%.Therefore, Mr. Dai signed a long-term cooperative purchase and sales contract with Bigolly.
Therefore, this trivalent chromium zinc passivator can be used when our colored zinc workpieces have slow coloring and poor corrosion resistance in the passivation process.If you are interested in this trivalent chromium color zinc passivator, please contact the Bigolly customer service for free samples and detailed technical information!
