Mr. Li from Ningbo, Zhejiang Province is the owner of an electroplating plant engaged in the production of galvanized various automotive parts and electrical parts. When Mr. Li's galvanizing automatic line was using a certain brand of blue-white passivator, there was always this problem: there was a time difference between the entry and exit of the workpieces into the tank, which resulted in uneven thickness and color of the passivation film, and it could not satisfy the customer's high quality requirements. So Mr. Li wanted to find a trivalent chromium blue-white passivator with uniform thickness and color appearance.
On this day, Mr. Li saw Bigely trivalent chromium blue-white passivator BZ-215 when he was searching on the Internet, so he inquired about the process parameters of this passivator and the uniformity of the passivation film. After understanding Mr. Li's production situation in detail, Bigely engineers explained that it was due to the passivation time range of this passivator is relatively narrow, so that the thickness of the passivation film of the upper row of workpieces will be thicker and the appearance of the color will be lighter; while the thickness of the passivation film of the lower row of workpieces will be thinner and the appearance of the color will be darker.
This trivalent chromium blue and white passivator of Bigely is prepared with imported raw materials, the workpiece passivating 10 seconds can obtain the appearance of blue and white color, and the workpiece passivating 90 seconds, the passivation film will not appear corrosion phenomenon, the appearance can still maintain blue and white without yellowing, and the workpiece consulting salt spray test white rust time in more than 96 hours. This can greatly meet the customer's high quality requirements for blue zinc workpieces in appearance color and corrosion resistance. After learning about it, Mr. Li was very interested in this passivator, so he first bought two barrels to try.
Under the guidance of engineers, Mr. Li used this passivator and found that the passivation time range of this passivator is relatively wide, the appearance of the upper and lower rows of workpieces after passivation can maintain a consistent blue-white color, and good corrosion resistance, which is fully able to meet the customer's requirements for the appearance of the workpieces of the good and performance requirements. Soon, Mr. Li placed another order and signed a cooperation agreement with Bigely.
Therefore, when the thickness and color of the passivation film of the workpieces in our automatic line are uneven during the blue zinc plating production process, try this trivalent chromium blue-white passivator from Bigely to reduce the occurrence of malfunction and effectively improve the production efficiency.
