For sanitary ware, furniture, electronics and other industries, the amount of stainless steel pipes is very large, and the mirror effect can not only improve the appearance, but also improve the heat resistance of the pipes; in actual use, it is found that the smoother the stainless steel pipes, the more Dirt is not easy to appear, and the daily cleaning and maintenance is very easy; what should be done for the mirror stainless steel pipe?
In order to achieve the mirror image effect, a polishing process must be used. First, check whether the pipe surface has any irreparable defects such as deformation, welding leaks, and gaps, and then polish it after confirming that it is correct.
1. Rough polishing: Use sandpaper to polish back and forth to remove various collisions between the welding point and the previous process left after the pipe fitting is welded, so that the weld will initially form a rounded corner, and there are basically no large scratches and collisions between the horizontal and vertical planes. ; The surface roughness of the stainless steel tube after rough polishing can reach R=mm.
2. Semi-precision polishing: Grind back and forth with sandpaper, the purpose is to correct the joints in the previous process, further the traces after rough grinding, and repeatedly grind the traces left in the previous process to achieve the goal of no scratches and basic brightness. . The surface roughness after processing is R-mm.
3. Fine polishing: Use sandpaper to grind the stainless steel tube back and forth. The purpose is to trim and grind the fine lines generated after the fine polishing, so that the joint between the polished part and the non-polished part basically disappears, and the surface of the stainless steel tube becomes brighter. The stainless steel polished in this process The surface of the tube is basically close to the mirror effect, and the surface roughness of the grinding part should reach R0.1mm.
4. Mirror polishing: first check whether there is light leakage and rough polishing on the surface of the stainless steel; then use a wool wheel with Daqing wax to imitate the previous processing method to process the mirror surface to achieve the mirror surface after the previous processing. Then wipe its surface with a clean cotton cloth to make its mirror reflectivity reach 6K or 8K.
Through the steps of rough polishing, semi-finish polishing, fine polishing, and mirror polishing, the surface finish of the steel pipe is improved. The entire processing process requires manual cooperation, and the main factors affecting the processing quality are the polishing intensity, angle and time. Therefore, when purchasing, it is better to choose a strong manufacturer with rich experience in technical personnel, which will increase the affirmation of the quality of stainless steel pipes.
