Dry. Dry to dry of course as well, the workpiece of the filling barley by boiling water should be inclined to stick on the iron shelf, so that the surface of the scattered water in the work to vulgar straight. The water mist that flows to the bottom corner is absorbed with pure cotton towel. The color of the film that is dried in this way is not affected. It looks sure.

        Maintenance of defective parts. It is advisable to find out the dry and aging process before, because the dry and aging film is difficult to remove and will harm the surface roughness of the surface of the industrial aluminum profile. This problem xiaobian has carried out some exploration in technology, through a variety of method experiments, found that the actual effect of the following method is very good, the method is simple, and does not harm the surface quality of the workpiece, the actual whole process is as follows: The first will not pass the industrial aluminum clamps on the fixture with aluminum oxidation, then according to the anodic oxidation treatment method of aluminum in sulfuric acid solution to carry out anodic oxidation treatment for 2 ~ 3min, to be soft, fall down, and then after the caustic soda solution slightly clean and sodium cyanide light can be carried out again conductive anodic oxidation treatment.
