Description
Technical field
The present invention relates to reaction field, metallic surface, relate in particular to novel liquor of hole-sealing tank of a kind of oxidized aluminum alloy section bar and method for sealing thereof.
Background technology
At present, the surface treatment mode of oxidized aluminum alloy section bar mainly is divided into two big types.One type be behind the section bar electrolytic oxidation again through the mode of electrophoretic painting, make the surface produce the organic membrane of layer of transparent, be called the electrophoresis section bar.Another kind of be the section bar electrolytic oxidation after, through directly using behind the sealing treatment, be called oxidation sealing of hole section bar as finished product.
As everyone knows, the current sealing of hole mode of aluminum current alloy oxidation section bar mainly contains two types of normal-temperature hole sealing and middle temperature sealing of holes.The two is all with the staple of nickel ion as the sealing of hole product; Both difference mainly is, the nickel ion that middle temperature sealing of hole oxidation fenestra absorbs is less, and surface color is white partially; The nickel ion that normal-temperature hole sealing oxidation fenestra absorbs is more, and surface color is green partially.Cause on the color major cause of difference to be because nickel ion itself shows green, it is green all the more that absorbed dose is got over the multilist face.
In recent years, the oxidized aluminum alloy section bar that a kind of surface color is green especially receives human consumer's favor, promptly so-called blue or green sand oxidation section bar gradually.Yet, want to reach the green especially effect in surface and can not rely on the raising nickel ion concentration to accomplish again merely; This is that the content of fluorion and nickel ion has certain proportion because the staple in the normal-temperature hole sealing tank liquor is a nickelous fluoride, if concentration is too high, oxidized surface can produce one deck sealing of hole ash, influences surface quality.
In view of this, it is green especially and don't influence the novel liquor of hole-sealing tank of surface quality very to be necessary to develop a kind of surface color.
Summary of the invention
