HL-510 High Performance bright acid copper plating acid copper electroplating process matting agent / alkaline copper brightener / nickel brightener / gun shade agent / acid copper brightener / tin plating brightener manufacturers wholesale optical agent / alkaline copper brightener / Nickel brightener / gun shade agent / acid copper brightener / tin brightener manufacturers wholesale Tel: 13580825571 Zhang Ping Hong QQ: 420118694 Company Website: http: //www.dghaolun.net acid copper plating bath preparation 1. inject the right amount water in preparation tank, heated to 40-50 ℃, the desired copper sulfate was added and stirred until completely dissolved, was added 2 g / l of activated carbon powder, followed by stirring at least one hour; 2. the plating solution was filtered into a filter pump Clean the plating bath, add water to nearly level, and clean the filter pump; 3. Slowly add the required amount of pure sulfuric acid, then it will generate a lot of heat, need vigorous stirring, so that the bath temperature did not exceed 60 ℃ (Note: When adding sulfuric acid, requires special care, should wear protective clothing, gloves goggles so as to ensure safety.); 4. The bath is cooled to about 25 ℃, adding an appropriate amount of hydrochloric acid or sodium chloride , the content of chlorine ions up to standard, add water to the water; 5. Under normal operating conditions, a small current electrolysis for 6-8 hours, and then follow the instructions to add the right amount of additives and stir again to normal after plating can be normal production. 4. Daily use acid copper plating additives and precautions 510A acid copper plating: main filled agent and luster to walk. Insufficient, filling of the entire current density area will decrease; when too much, the low current density area filled of sharp decline, there will be a clear demarcation with the coating in other locations. Daily consumption by 60-90 ml / 1000 ampere-hours. 510B acid copper plating: brightener. Insufficient, the coating is easy to burn; excessive, poor or low potential brightness from white mist. Daily consumption by 50-80 ml / 1000 ampere-hours. 510MU acid copper plating: with a wetting agent, an acid copper base brightener. Insufficient coating prone to pitting in serious condition occurs when loose striped plating high potential in the region; severe overdose, low potential will produce fog coating. Daily consumption by 50-80 ml / 1000 ampere-hours.
