Description

technical field

[0001] The invention relates to polishing technology, in particular to an aluminum alloy polishing liquid and a preparation method thereof. Background technique

[0002] Due to their special properties, aluminum and aluminum alloy products are widely used and occupy an extremely important position in the hardware market. Aluminum products must be polished in surface treatment, which not only makes the appearance of aluminum products bright, but also uniform and smooth The surface can be dispersed to reduce the adsorption of corrosive media and improve the anti-corrosion performance.

[0003] Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. At present, the main polishing technology is tri-acid polishing.

[0004] Aluminum alloy tri-acid polishing technology has the following four defects that limit the application of polishing technology: [...
