    We all know that potassium chloride galvanized brightener is widely used for its advantages of low preparation cost, fast lightening, and good brightness.In order to effectively reduce the occurrence of failures, what details should we pay attention to when adding potassium chloride galvanized brightener?

    Bigolly Technology analyzes the characteristics of the product potassium chloride galvanizing brightener BZ-528 based on the field experience. The correct addition of brightener is very important.,When adding potassium chloride galvanizing brightener, you should pay attention to these 4 points:

    1. Reasonable addition within the scope of the electroplating process.The premise of potassium chloride galvanizing brightener to fully play its role is that the composition of the bath and the pH value and other conditions are properly adjusted.If there is too little potassium chloride in the over-plating solution, no matter how the addition of agent A can not achieve good deep plating ability; too little boric acid can not be solved only by brightener.

    2. Adhere to the principle of adding a small amount multiple times.This principle applies to most brighteners. Some factories use high-position barrels and the method of continuous dripping with medical infusion parts to avoid the quality fluctuations. After all, too little or too much potassium chloride galvanizing brightener is harmful and not beneficial.

   

    3. Most of the benzylidene acetone, which is a potassium chloride galvanized brightener, has a large amount of crystals precipitated at the bottom of the plastic bucket in winter. It is best to place the bucket together in hot water with a liquid temperature greater than 80 °C for more than 0.5 hours, and shake well. Add it after it is dissolved, otherwise the supernatant liquid will have less main light agent and more carrier, and it will be more likely to cause excessive accumulation of surfactant after adding, resulting in a series of side effects.

    4. For the long-used plating solution, the electrolytic consumption of the main light agent is fast, and the surfactant is only accumulated in the plating solution due to the adhesion of the coating layer and the loss of the carry-out, which cannot be removed by activated carbon.If only the brightness is insufficient, you can directly purchase high-quality benzylidene acetone or o-chlorobenzaldehyde, dissolve it in alcohol, and add it directly to the tank under constant stirring.Because the content of surfactant and carrier brightener in the plating solution has long been greater than the critical concentration for forming micelles and micelles, it can still disperse and solubilize benzylidene acetone to dissolve it.

    Therefore, we need to pay attention to the above four points when adding potassium chloride galvanizing brightener, which can effectively reduce the failure rate and save costs.If you are interested in potassium chloride galvanizing brightener, please contact bigolly customer service, you can get free samples and detailed technical information!
