A good potassium chloride galvanizing brightener is not only reflected in the bright uniform appearance, but also has a superior performance, and through the performance test can understand the brightener is good or bad. Take BZ-528 potassium chloride galvanizing brightener of Bigely Technology as an example for performance test:

1. Turbidity point test. Take 50ml BZ-528 into a 100ml colorimetric tube, insert a thermometer, and heat up until the solution becomes cloudy, then take it out and cool it until it is clarified, and record the temperature when the solution becomes clarified as the turbidity point. The turbidity point of BZ-528 brightener was 80℃.

2. Measurement of current efficiency. The current efficiency is calculated by the weight difference and the current amount of the test plate before and after plating. The experimental results show that the current efficiency of BZ-528 brightener is 98%.

3, Plating performance test. The plating time was 10min under the test condition of current intensity of 1A with 250ml Hull tank. when BZ-528 brightener was added to the plating solution, the bright range of the plated layer was obviously enlarged. The Hull bath test with cathodic current density of 0.5-2A/dm2 resulted in a satisfactory bright galvanized layer.

Through the above tests, it can be seen that the galvanizing process using the BZ-528 potassium chloride galvanizing brightener of Bigely Technology has a current efficiency of more than 98%. And the current density range is wide, which is easy to operate in the actual production process. Guangdong Bigely Technology Co., Ltd. was founded in 2003, 15 years focusing on potassium chloride galvanized brightener R & D and manufacturing, is a research and development, production, sales, service as one of the high-tech enterprises. Bigely's potassium chloride galvanized brightener is mature and stable, easy to maintain, and has obvious advantages.
