Abstract
The invention relates to the technical field of aluminum product processing, in particular to an acid etching method for aluminum alloy parts. Degreasing cotton is utilized to take ethyl acetate to erase oil dirt on the surfaces of the aluminum alloy parts, then the aluminum alloy parts are flushed by water for 10 minutes, and the aluminum alloy parts are scrubbed by acetone for twice; the aluminum alloy parts are put into acid etching fluid, the treating temperature is 70 DEG C, and the treating time is 1 minute; and the aluminum alloy parts are fished out and flushed by water until the pH value of the flushing water returns to neutral, and the aluminum alloy parts are dried in the temperature of 100 DEG C. The acid etching method for the aluminum alloy parts is simple in operating process. As a formula and a preparing method of the acid etching fluid are reasonably designed, the acid etching effect and the acid etching quality of the aluminum alloy parts are improved.
Description
Technical field
The present invention relates to aluminum products processing technique field, specifically relate to a kind of Al-alloy parts acid etching method.
Background technology
In aluminum products industry, acid etching is absolutely necessary treatment process, and traditional acid etching liquid and reaction are too fierce, and constant product quality is poor, and F ion not easily detects, and controls comparatively difficulty.
Summary of the invention
For the technical problem existed in prior art, the object of the present invention is to provide a kind of Al-alloy parts acid etching method, for achieving the above object, present invention employs following technical scheme:
A kind of Al-alloy parts acid etching method, step is as follows:
Step 1., use absorbent cotton to glue to get the greasy dirt on ethyl acetate erasing Al-alloy parts surface, then rinse 10 minutes with water, then use acetone to clean 2 times;
2., by Al-alloy parts step puts into acid etching liquid, and treatment temp is 70 DEG C, and the treatment time is 1 minute;
Step 3., pull rear water out and rinse until the pH value of wash-down water returns to neutrality, dry at 100 DEG C.
Preferably, the acid etching liquid that 2. described step uses is made up of 50 parts of phosphoric acid, 5 parts of laureth sodium sulfovinates, 5 parts of nitric acid, 0.5 part of crotonoside, 5 parts of aluminium, 0.5 part of carbonic acid diamines and 60 parts of water.
Preferably, the preparation method of the acid etching liquid that 2. described step uses is: in container, first add 5 parts of laureth sodium sulfovinates and 20 parts of water, stirs 5 minutes; Then slowly add 5 parts of nitric acid, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 50 parts of phosphoric acid and 10 parts of water, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 0.5 part of crotonoside and 0.5 part of carbonic acid diamines, limit edged stirs, and stirs 5 minutes after interpolation; Finally slowly add 5 parts of aluminium and 30 parts of water, stir 15 minutes.
Beneficial effect of the present invention shows:
1), the acid etching liquid that uses in acid etching method, its formulating of recipe is novel, rationally, particularly with the addition of a small amount of crotonoside, can significantly improve the processing efficiency of acid etching liquid, react comparatively gentle.By acid etching liquid with the use of, make the stability of acid etching Al-alloy parts better, each component easily detects.
2), the preparation method of acid etching liquid, by the method for progressively adding and appropriate design order of addition(of ingredients), the solubility property between each material can not only be improved, the possibility of particle agglomeration can also be avoided, the surface protecting function of acid etching liquid is promoted significantly.
3), Al-alloy parts acid etching method, operating procedure is relatively succinct, by formula and the preparation method of appropriate design acid etching liquid, thus improves Al-alloy parts acid etching effect and quality.
