Mr. Ye is the owner of an electroplating factory in Xiamen, Fujian.His production line is mainly for galvanized processing and production of hinge fasteners.The alkaline galvanizing additive he used before was introduced by his master. Although the coating of the workpiece after using this additive has a normal appearance, it has poor salt spray resistance and cannot meet the needs of production.So Mr. Ye wanted to find an alkaline galvanizing additive with good salt spray resistance.
One day, Mr. Ye found Bigolly Technology through Internet search and communicated with the engineer in detail.After the engineer understood Mr. Ye's requirements for the workpiece, he recommended Mr. Gao to use the alkaline galvanizing additive BZ-515 with the trivalent chromium blue passivator BZ-212.In this way, when the thickness of the galvanized layer of the workpiece is about 5μm, the neutral salt spray resistance test can be more than 120 hours, which can fully meet Mr. Ye's requirements for the performance of the workpiece.So Mr. Ye proposed to send samples to the engineer for proofing first.
After receiving the samples, Bigolly engineers used the alkaline galvanizing additive BZ-515 and the trivalent chromium blue passivating agent BZ-212 for passivation according to the production process of Mr. Ye's production line.On the same day, the engineer will proof the workpiece and send it back to Mr. Ye.10 days later, Mr. Ye called and said that the batch of workpieces for proofing had all passed the test.The coating thickness of the workpiece is 4~6μm, and the salt spray test can reach more than 120 hours, which is much better than the brightener used before.So, Mr. Ye and Bigolly signed a purchase contract.
Therefore, when our hinge fasteners are galvanized, it is recommended to use this alkaline galvanizing additive BZ-515 with trivalent chrome blue passivator BZ-212, which can ensure good salt spray resistance of the coating.If you are also looking for such an alkaline galvanizing additive with good salt spray resistance,please contact Bigolly customer service to get free samples and detailed technical information!
