Many electroplating factories have reported that the substrate is over-corroded during the pretreatment degreasing process. So, what kind of aluminum alloy degreasing powder can ensure that the substrate is thoroughly degreased without being over-corroded? In this issue's article, we'll introduce it.
Aluminum, being an amphoteric metal, undergoes chemical reactions with both acids and alkalis at a rapid rate. To ensure thorough oil removal, some electroplating plants choose to use aluminum alloy degreasing powder containing strong alkalis. Although strong alkalis can help quickly clean up oil stains, this is a double-edged sword. While it powerfully removes oil, it also causes excessive corrosion to the surface of the aluminum alloy.
What will happen if there is excessive corrosion? Some communication and electronic products use aluminum alloy materials to make the base plate and cover plate of the main unit. If they are overly corroded, it will aggravate the intergranular corrosion of the metal, and crystal patterns will appear on the surface of the aluminum alloy. How can these rough textures be concealed? I'm very sorry. Even with the best electroplating process, it still can't be achieved. The appearance of the plated products will definitely be substandard (and the performance of the products will also be affected).
Therefore, choosing the right degreasing powder is a matter that cannot be ignored. More and more electroplating plants choose to use Bigelai's aluminum alloy degreasing powder BC-19. As a new type of cleaner without strong alkali, it has the following features: Weakly alkaline, with a mild formula, it does not corrode aluminum materials. After the workpiece is degreased, it can maintain its original luster and will not show dullness or roughness. Begle engineers have conducted comparative tests. Some strongly alkaline degreasing powders on the market can damage the aluminum alloy base material, while BC-19 will not. After customers use this aluminum alloy degreasing powder, not only is the degreasing efficiency high, It can also lay a good foundation for the quality of subsequent electroplating production.
