Mr. Chen from Yantai, Shandong is the owner of an electroplating factory engaged in galvanizing processing of various daily hardware and building hardware workpieces. Recently, Mr. Chen's passivation film on colored zinc workpieces has always experienced fogging, which has led to customer complaints. Many workpieces require return and rework, resulting in low production efficiency. Therefore, Mr. Chen wants to replace it with an environmentally friendly trivalent chrome colorful zinc passivator that will not fog.
One day, Mr. Chen saw Bigley's environmentally friendly zinc passivation agent BZ-208 while searching online. He asked about the performance of this passivation agent and whether there would be fogging of the passivation film during the production process. After understanding Mr. Chen's production situation and the use of passivating agents, engineers from Bigley discovered that Mr. Chen's colored zinc process requires the use of alkaline solution to adjust the pH value during production.
So I explained to Mr. Chen that some color zinc passivating agents on the market have a low pH value, and after adjusting the pH value with alkaline solution, the passivation film is prone to blooming and fogging, resulting in poor corrosion resistance of the passivation film. In addition, some passivating agents have low tolerance for impurities such as zinc and iron, and the passivation film of workpieces is also prone to blooming and fogging.
And this environmentally friendly zinc passivation agent BZ-208 was developed by the R&D team of Bigley for 2 years, and it is produced using imported raw materials. The workpiece can obtain a uniform and bright passivation film, which does not fade or change color. During the production process, there is no need to adjust the pH value with alkaline solution. The passivation film of the workpiece can avoid fogging and blooming, and the operation is simple. In addition, the passivation solution has a high tolerance for metal impurities such as zinc and iron, which can reduce the aging frequency of the passivation solution and save production costs. After Mr. Chen learned about this passivation agent, he decided to buy a bucket first and try it out.
Under the guidance of the engineer, Mr. Chen used this environmentally friendly color zinc passivation agent BZ-208. During the production process, there is no need to add alkaline solution to adjust the pH value, and the operation is simpler. After the passivation of the workpiece, the film layer no longer shows fogging and blooming, greatly reducing the defect rate of the workpiece; And the corrosion resistance of the workpiece has greatly improved. Previously, the workpiece could only pass a neutral salt spray test for 48 hours, but now it can pass a salt spray test for 96 hours, which has also been recognized by many customers. Soon, Mr. Chen placed another order and signed a cooperation agreement with Bigley.
So, the passivation film of colored zinc workpieces is prone to fogging and blooming. Try the eco-friendly colored zinc passivation agent BZ-208 from Bigley, which effectively reduces the defect rate of workpieces and improves production efficiency, thereby greatly reducing deep production costs.
