Technical Field

The invention relates to the technical field of material processing, in particular to a method for treating the surface of a profile.

Background

At present, the method for processing the surface of the section by adopting a spray etching treatment mode has the problems of poor uniformity and consistency of the surface of the section after the spray etching treatment.

Thus, the existing methods for treating the surface of the profile still need to be improved.

Disclosure of Invention

The present invention has been completed based on the following findings of the inventors:

after intensive research on the spray etching treatment mode adopted at present, the inventor finds that different areas on the surface of the section are contacted with the etching solution successively because the section is usually placed on a conveyor belt and conveyed to an area sprayed with the etching solution in the spray etching treatment process. In order to prevent the section from falling off and deviating, the conveying speed of the conveying belt cannot be too high, so that the etching reaction time of the part of the surface of the section, which is firstly contacted with the etching solution, is longer, and the etching reaction time of the part of the surface of the section, which is secondly contacted with the etching solution, is shorter, so that an inconsistent etching effect is generated on the whole surface of the section; in addition, in the existing method for processing the surface of the profile, the surface of the profile is directly polished after etching, and the polishing can seriously thin the profile, so that rework etching cannot be carried out if the etching process is poor. That is, the inventors have found, after study, that the etched product should be inspected before the polishing process is performed to screen out the product in which poor etching occurs.

Based on the above, an object of the present invention is to provide a method for treating a surface of a profile, which is simple, convenient, easy to implement, and easy to industrially produce, and when performing a spray etching treatment on predetermined areas of the surface of the profile one by one, a reaction rate of etching the predetermined area first contacted with an etching solution is slowed down, a difference between degrees of etching reactions occurring in the predetermined area and the predetermined area later contacted with the etching solution is reduced, or consistency of etching reactions occurring in each predetermined area of the surface of the profile can be ensured.

In one aspect of the invention, a method of treating a surface of a profile is provided. According to an embodiment of the invention, the surface comprises at least two predetermined areas, the method comprising: cooling the predetermined area; and performing spray etching treatment on the predetermined regions subjected to the cooling treatment one by one. The inventor finds that the method is simple and convenient to operate, easy to realize and easy for industrial production, and when the preset areas are subjected to spray etching treatment one by one, the reaction rate of etching in the preset area which is firstly contacted with the etching solution is reduced, and the preset area which is then contacted with the etching solution is not contacted with the etching solution. After that, the predetermined area which is contacted with the etching solution later is also contacted with the etching solution, and the predetermined area which is contacted with the etching solution earlier and the predetermined area which is contacted with the etching solution later are etched simultaneously. Then, because the predetermined area is cooled before the etching treatment, the reaction rate of the etching reaction is slowed down when only the predetermined area which is firstly contacted with the etching solution is contacted with the etching solution and then the predetermined area which is contacted with the etching solution is not contacted with the etching solution, so that the degree of the etching reaction of the predetermined area which is firstly contacted with the etching solution and the degree of the etching reaction of the predetermined area which is secondly contacted with the etching solution are as same as possible, and the consistency of the etching reaction of each predetermined area on the surface of the profile is ensured.

According to an embodiment of the present invention, the time of the first spray treatment may be 5s to 120s, and preferably, the time of the first spray treatment may be 10s to 20 s. In some embodiments of the present invention, the time of the first spraying process may be 10s, 12s, 14s, 16s, 18s, 20s, or the like.

After that, the predetermined area which is contacted with the etching solution later is also contacted with the etching solution, and the predetermined area which is contacted with the etching solution earlier and the predetermined area which is contacted with the etching solution later are etched simultaneously. Then, because the predetermined area is cooled before the etching treatment, the reaction rate of the etching reaction is slowed down when only the predetermined area which is firstly contacted with the etching solution is contacted with the etching solution and then the predetermined area which is contacted with the etching solution is not contacted with the etching solution, so that the degree of the etching reaction of the predetermined area which is firstly contacted with the etching solution and the degree of the etching reaction of the predetermined area which is secondly contacted with the etching solution are as same as possible, and the consistency of the etching reaction of each predetermined area on the surface of the profile is ensured.

According to the embodiment of the invention, the etching solution is a solution containing frosting powder. In some embodiments of the present invention, the mass ratio of the frosting powder to the water in the solution containing the frosting powder may be (3-7): 2, in particular, may be 3: 2. 4: 2. 5: 2. 6: 2 or 7: 2, etc. In some embodiments of the present invention, the roughness of the frosting powder may be 0.1 μm to 0.2 μm, and specifically may be 0.1 μm, 0.15 μm, or 0.2 μm, etc. The frosting powder may include 40 to 50 parts by weight of citric acid, 40 to 50 parts by weight of ammonium bifluoride, 1 to 3 parts by weight of barium sulfate, 5 to 10 parts by weight of ammonium fluorosilicate, and 1 to 5 parts by weight of a buffer, which may be specifically ammonium fluorosilicate, ammonium hexafluorosilicate, or the like. Therefore, the etching effect on the section bar is better, and the etching solution is particularly suitable for etching glass and has lower cost.
