Background technology
Aluminium section bar needs to clean aluminium section bar before spraying during the manufacturing, and aluminium section bar adds in production
Working hour, its surface was unavoidably accompanied with grease dust, if do not cleaned to it, aluminium section bar after spraying it is easy to appear
Be corroded, corrosion the case where, influence the quality of aluminium section bar, existing aluminium section bar cleaning way is relatively simple, and the effect of cleaning is non-
It is often poor, cause the case where short time just will appear to fall paint, be corroded after spraying aluminum profile.
Invention content
In view of the above technical problems, the invention discloses a kind of aluminium section bar cleanings cleaned up.
The invention discloses a kind of cleanings of aluminium section bar, include the following steps：
1）It impregnates：Aluminium section bar is placed in the clear water that water temperature is 50 DEG C and is impregnated 5-10 minutes；
2）Scrub：The aluminium section bar after impregnating is then taken out, is rinsed with clear water while scrubbing aluminium shape surface with hairbrush；
3）Degreasing：Aluminium section bar is put into 20 DEG C -25 DEG C of degreasing agent tank liquor, is impregnated 3-5 minutes, and ceaselessly stir degreasing
Agent then takes out aluminium section bar；
4）Washing：The aluminium section bar taken out from degreasing agent is rinsed with clear water, until washing away degreasing agent completely；
5）Pickling：Then by step 4）Aluminium section bar after washing is put into hydrofluoric acid and adds to be impregnated 2-4 minutes in the pickle of nitric acid, is soaked
Pickle is heated to 40 DEG C -55 DEG C while bubble and is ceaselessly stirred；
6）Table tune：Aluminium section bar after pickling is put into colloidal titanium saline solution and is impregnated 2-5 minutes, and ceaselessly stirs colloidal Ti-salt
Liquid；
7）Phosphatization：Aluminium section bar after table tune is put into phosphating solution and is impregnated 5-10 minutes, by the temperature of phosphating solution while immersion
It is arranged at 40 DEG C -50 DEG C；
8）Passivation：Then the aluminium section bar after phosphatization is placed in passivating solution and is passivated；
9）It washes again：Aluminium section bar after passivation is washed using overflow, aluminium section bar is further taken out and dries.
Further：The degreasing agent tank liquor is that HF, Fe, H2O2, NO and non-ionic surface is added in H2SO4 or H3PO4
Activating agent.
Further：The preparation method of the phosphating solution is：150kg water is first added into slot, is then added 50kg's
Yj-1360 finally adds the water of 50kg.
A kind of cleaning of aluminium section bar of the present invention, advantage are：Degreasing of the present invention, pickling, table tune, phosphorus
Wash and etc. can effectively clean the impurity of aluminium shape surface, improve the corrosion resistance of aluminium section bar.
