What is the effect of ink on the phenomenon of boiling off aluminum in aluminum plating water?
Because vacuum aluminizing is to evaporate aluminum into aluminum vapor under high vacuum, and then plating on the surface of the film to form a layer of bright and dense aluminum layer, while the common composite ink binder mostly uses chlorinated polypropylene and chlorinated EVA materials, and this kind of material will decompose at high temperature, release hydrogen ions and chloride ions, and then react with Al to form aluminum chloride Material, aluminum layer will be black and partially disappear. At the junction of the printing pattern and the blank, due to the difference in thickness, the thickness of the adhesive layer will also be uneven, so the phenomenon is more obvious. In addition, a larger amount of glue, will also play a good role in blocking, blackening phenomenon will be reduced.
