Wax water glasses, water glasses, wax manufacturers, glasses wax water sales, glasses wax water erosion processes and degreasing aluminum alloy material, the aluminum metal in a continuous reaction, while the middle of the other elements of the metal alloy generally can not participate reaction, these metal impurities wastewater treatment residues in aluminum alloy surface, which is usually called "hanging gray" need to go through rigorous cleaning process, to avoid affecting the appearance quality plating. Descaling process is very important for the alloy plating, the plating layer directly affect the bonding strength. Process for pure aluminum and aluminum-manganese alloys, generally with 50% nitric acid treatment, the silicon-containing aluminum alloy components, adding a sulfuric acid before the cleaning process, and use the "three points of 48% nitric acid + 1" hydrofluoric acid mixed solution soak for 3-5S process, while the flow of sand holes in the possession of pollutants stripped out to achieve thorough cleaning and removal of ash hanging surface effect. When etching using sodium hydroxide dissolved in the cleaning solution will gradually increase in the aluminum to produce aluminum hydroxide precipitate, because some intermediate cleaning solution or complexing agent is added to sodium gluconate, aluminum cleaning speed is very strict control , is too slow, it may because of severe corrosion, resulting in plating piebald issue. After cleaning aluminum and transferred to the need to quickly wash sink zinc process, try to avoid an oxide layer formed on the surface of aluminum, aluminum alloy into the acid etching before, the best drying water to prevent localized over aluminum corrosion. Shen zinc processing, because aluminum can not be direct plating requires an intermediate layer deposited on top can only be electroplated other deposits. Relatively close with aluminum metal lattice mainly zinc or zinc-nickel alloy layer, and therefore need to go through before plating aluminum sink zinc processing, on a clean surface deposited a thin layer of dense layer of zinc, and then plating. Shen Shen zinc processes generally use secondary zinc process better. Shen water reuse zinc recipes require great attention to the ratio of different components, preferably zinc sink a small amount of ferric chloride solution was added to help improve adhesion. Aluminum plating zinc secondary sink to strictly control the processing time, the first time is about Shen zinc 40-60S, the second time is about Shen zinc 15-20S, a long time will form a rough dry sink zinc layer, causing pitting poor plating.
