As a China Aluminum Tube System Supplier, let's talk about the flat polishing and fine ash removal of the Aluminum Tube System.
The flat polishing bath is usually provided with two purposes, namely, flat polishing and fine ash removal on the sand polished Aluminium Tube System.
1. Flat Polishing: The flat polishing bath can generate a certain thickness of oxide film and greatly increase the brightness of the Aluminum Tube System. Since the anodizing causes the Aluminium Tube System after the sand-bloss polishing to be lost, the flat light is polished first, and the surface light forms a dense oxide layer, which fixes the gloss, and then anodizes to greatly reduce the loss of light; in addition, Aluminum Before the Tube System is polished from the sand surface to the anodizing, it needs to be washed several times, and may be retained in the air or in the washing tank to cause pitting. If the flat polishing bath is first passed, a certain thickness of the chemical oxide film is prefabricated and protected first. Pitting corrosion or flower material in the washing tank before oxidation is avoided to improve the yield.
2. Fine ash removal: acid ash is very stubborn, and the method is difficult to remove. Will seriously affect the appearance quality of the acid corrosion material. Although the sand surface polishing tank can remove most of the acid ash, there may still be a small amount of residue under certain special conditions. The flat polishing bath completely removes the acid ash, thus ensuring the quality of the Aluminum Tube System and completely eliminating the contamination of the coloring tank and the electrophoresis tank by the acid ash.
