In the link of electroplating treatment, pre-treatment oil removal is an important link, which will affect the subsequent production. Therefore, strict control of process parameters and the use of steel chemical degreasing powder are things that need to be paid attention to. When you encounter a failure, you need to troubleshoot from several directions.
Fujian Mr. Deng is the owner of an electroplating factory, recently in the anodic electrochemical degreasing of steel parts, some steel plating parts appear reddish-brown deposits on the surface. Mr. Deng was distressed about this, because after removing it, it was found that the matrix of the corresponding part had been seriously corroded. This is time-consuming and laborious for the electroplating factory, but also suffered losses.
At the beginning, Mr. Deng thought that the operating temperature was too low, and the temperature of the electrochemical degreasing solution was measured at 85 ° C, which was within the process range, so it was excluded. Then it was speculated that the current density was too high, so the current density was detected, and the data was 1.1 A/dm2, which did not exceed the process range. That possibility is also ruled out. Mr. Deng felt annoyed.
One day, he searched Bigely Technology on the internet and decided to ask our engineers for help to try. Engineers rushed to the scene to investigate, pointed out that it may be due to the degreasing solution composition is too low, because when the degreasing solution of NaOH concentration is reduced, the anode area of the solution PH value will drop, then the degreasing rate will be reduced, the oxygen precipitation increased, then the surface of the plated parts began to oxidize and the appearance of adhesion, and will even produce obvious brown rust. After sampling and analyzing, it was found that this was indeed the cause.
After communication, we know that Mr. Deng used a chemical degreasing powder produced by a manufacturer before, because the formula ratio design is unreasonable, resulting in this production failure. In fact, if Mr. Deng could have known Bigely steel chemical degreasing powder BC-1101 earlier, he would not have encountered this situation. This degreasing powder has fast degreasing speed, strong degreasing ability, easy cleaning, and is suitable for high and low temperature operation. Wide operating range, easy to control. The composition ratio is also reasonable.
