Abstract
The invention discloses electrochemical polishing solution of aluminum and aluminum alloy. The electrochemical polishing solution consists of the following components in part by weight: 35 to 55 parts of 98 percent H2SO4, 350 to 550 parts of 85 percent H3PO4, 200 to 300 parts of ethylene glycol, 5 to 15 parts of 40 percent HF and 80 to 100 parts of H2O. The electrochemical polishing solution solves the problem of environmental pollution of hexavalent chromium, the energy consumption is reduced, and the brightness of the electrochemical polishing solution is superior to that of the traditional chromium-containing electrochemical polishing solution. The polishing solution has the advantages of low cost, high speed and long service life, furthest improves the working environment, and improves the quality of a polished surface; and the surface topographies of the aluminum and the aluminum alloy before and after polishing and after film sealing, observed by using a metallographic microscope, are fully superior to those of the traditional electrochemically polished aluminum and aluminum alloy.
Description
Technical field
The present invention relates to a kind of polishing fluid, relate in particular to the electrochemical polish liquid of a kind of aluminium and aluminium alloy.
Background technology
It is the preceding important manufacturing procedure of metal processing that polished finish is carried out on the metal parts surface, aluminium and alloy product are because of having special nature, therefore use quite extensive, in the hardware market, occupy extremely important status, aluminum products will polish in surface treatment, this not only makes the outward appearance of aluminum products have the appearance of light, and uniform and smooth surface can disperse to reduce the absorption of corrosive medium, the raising etch resistant properties.The electrochemical etching quality of aluminium and aluminium alloy is better than chemical rightenning.The reflection lampshade that luminance brightness is had relatively high expectations, cosmetics of super quality packing box etc. generally adopt the electrochemical etching method.The electrolytic solution of electrochemical etching also is divided into acid and alkaline two classes.Alkali silicon polishing liquid cost is lower, but comparatively serious to the corrosion of aluminium, and polishing effect is also not ideal enough. so acid polishing slurry is more widely used.With getting more polishing fluid is so-called three acid (phosphoric acid-sulfuric acid-chromic acid) polishing fluids, its technical maturity, steady quality.But chromate waste water is a serious problem to the pollution of environment, develops the Chrome-free polishing technology and more and more comes into one's own.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of raising glazed surface quality, and a kind of aluminium that cost is low, speed is fast, the life-span is long and the electrochemical polish liquid of aluminium alloy improve Working environment greatly.
