TECHNICAL FIELD

[0001] The present application relates to a polishing device, in particular to a wall polishing device for building decoration. BACKGROUND

[0002] The wall polishing device plays a crucial role in building decoration, and its main functions are as follows: 1) During the decoration process, whether it is a newly built wall or a renovated wall, there may be unevenness problems such as protrusions, depressions or construction marks. The wall polishing device can effectively eliminate these unevenness through meticulous polishing work, making the wall achieve a high degree of flatness and laying a good foundation for subsequent decoration work such as paint or wallpaper laying. 2) The polished wall has a smoother and more uniform surface, which can increase the contact area between the paint and the wall, thereby improving the adhesion of the paint and reducing the occurrence of peeling, cracking and other phenomena. This is of great significance to ensure the quality of decoration and prolong the service life of the decoration effect. 3) Wall polishing not only removes defects, but also adjusts the gloss and texture of the wall through different degrees of polishing to meet different decoration style requirements. Whether it is matte, semi-gloss or high-gloss effect, appropriate polishing can make the wall have a more uniform and beautiful appearance. 4) Traditional manual polishing is not only time-consuming and labor-intensive, but also difficult to ensure consistency and uniformity. Modern wall polishing devices, such as electric polishers and dust-free polishing systems, greatly improve the efficiency of polishing work, reduce the labor intensity of workers, and also reduce dust pollution during polishing, making the construction site cleaner and safer.
