Description
Technical field
The present invention relates to a kind of basic chemical polishing liquid and basic chemical polishing method, belong to industrial polishing technology field.
Background technology
The product of aluminum alloy materials is very many; the part shape complexity is various; and operation, turnover are more in the course of processing, because the material of aluminium alloy is softer, are very easy to scratch, damage; cause part to use; packaging protecting is also kept away the scuffing of unavoidable part, the generation of damaging howsoever, and traditional mode adopts the method for mechanical polishing can't satisfy the needs of product; the method of employing electropolishing has can't satisfy the product size requirement, mainly is the electropolishing lack of homogeneity.
The restriction that is not subjected to part shape, size is processed in chemical rightenning, do not need special frock clamp, once can process more part, now increasing enterprise adopts chemically polishing method to process, chemical rightenning is to utilize the chemical solution of definite composition to the surface of microcosmic injustice, the metal at outstanding position is dissolved fast, thereby just flat microcosmic plane surface not reach the effect of light.Because aluminium is amphoteric metal, so can obtain brightness effect with strong acid polishing fluid and strong basicity polishing fluid, after aluminium alloy is subject to oxidizing reaction, the speed of at a certain temperature aluminium alloy dissolving is corroded product and spreads gradually controlledly from the surface, and just plays polishing action when all electromotive force enough make anode potential reach corresponding oxidizing potential.
And the actual polishing fluid that uses is the strong acid polishing fluid mostly, contain phosphoric acid 60～70%, sulfuric acid 15～25%, nitric acid 10～20%, even higher, although the chemical rightenning for fine aluminium and duralumin adapts to better, produces a large amount of NOx gases when polishing, and is seriously polluted, solution is easy to wear out, cost is higher, and is larger to health and working the mischief property of environment, simultaneously, ununiformity and corrodibility also appear in surface of polished easily, tubercular corrosion occurs easily, dissolution rate is also very fast, is not the needs that adapt to very much alloy product.
Also exist in addition a kind of without the tobacco chemical brightening solution, mainly be in acid polishing slurry, to have added certain chemical substance without the tobacco chemical brightening solution, substitute nitric acid or added the additive that suppresses the oxynitride effusion, thereby reduce the discharging of oxynitride, but of low quality after the polishing mainly is the polishing that is applicable to fine aluminium, after the aluminium alloy polishing, the surface does not reach polishing effect, and burnt hair is brightless, can not meet the needs of production.
And a kind of basic chemical polishing liquid of comparative maturity does not also appear on the market.
Summary of the invention
The object of the present invention is to provide a kind of basic chemical polishing liquid and basic chemical polishing method, can solve the problem that the scuffing of aluminum alloy part is damaged, improve Part Surface Roughness, reduce production costs.
The objective of the invention is to be achieved through the following technical solutions: a kind of basic chemical polishing liquid comprises the component of following content in every 1L basic chemical polishing liquid:
Described solvent is the technical pure water purification.
A kind of basic chemical polishing method is mainly used in the polished finish of aluminium alloy, and it comprises following steps:
(1), the pending place that lip-deep hard defects, the cut of aluminum alloy part is darker is tied with sand paper first, then carries out mechanical sandblasting, removes the vestige of sand papering;
(2), the temperature with above-mentioned basic chemical polishing liquid is heated to 90～100 ℃;
(3), aluminium alloy is put into above-mentioned basic chemical polishing liquid carry out the selective autolyzing solution and be used for surface smooth and the polished aluminum alloy, the time of putting into is 5～15s, namely finishes the polished finish to aluminium alloy.
Utilize aluminium and aluminium alloy selective autolyzing solution in basic solution to be used for smooth and surface polished aluminum, improve the chemical process of its surfaceness, the chemical equation of its polishing process is:
2Al+6NaOH→2Na
3AlO
3+3H

3+2NaOH→2NaAlO

Sodium hydroxide has corrosion leveling effect; Sodium Nitrite has the leveling polishing action; the diffusion layer that sodium phosphate meeting formation one deck in reaction contains aluminium salt is adsorbed on the aluminium material surface; solubilizing reaction is proceeded; the aluminum ion that produces must pass diffusion layer and enter solution; therefore the dissolution rate of aluminium is subject to the control of thickness of diffusion layer; the toughness thickness of diffusion layer at calixconcavity place, aluminium surface is obviously greater than the thickness at its protrusion place; causing aluminum ion to be difficult to be diffused in the solution goes; consequently the aluminium at aluminium material surface calixconcavity place is subject to the protection of toughness diffusion layer; dissolution rate becomes slowly, and the aluminium at uneven surface protrusion place can comparatively promptly dissolve, and reaches the leveling effect.
Sodium Fluoride mainly plays the effect of promotor, can effectively suppress to produce the spot corrosion effect in the polishing process, improves its polishing effect.
Beneficial effect of the present invention is: utilize aluminium and aluminium alloy selective autolyzing solution in basic solution to be used for smooth and surface polished aluminum, solved the problem that the scuffing of aluminum alloy part is damaged, improve Part Surface Roughness, reduced production cost, also can not cause environmental pollution.
