Outdoor ice rinks and indoor ice rinks are common places for ice sports such as speed skating, curling, and ice hockey. With the popularity of ice and snow sports, the public and professional athletes have higher and higher requirements for ice surface. Because the process of ice shoveling and ice making is difficult to be absolutely uniform, and some structures of the ice making machine, such as tires and steel knives, will leave traces on the ice surface, resulting in tiny scratches, pits and bumps on the ice surface. rise. These defects not only affect the aesthetics of the ice surface, but also make the ice surface rougher, which in turn affects the actual sports experience, and even becomes a potential risk factor in some high-speed racing sports. At present, steel knives are usually used to remove defects on the ice surface, but steel knives can only remove large and significant defects on the ice surface, but cannot remove small defects.

To this end, as shown in FIG. 1, an embodiment of the present invention provides an ice surface polishing method, and the ice surface polishing method includes:

Step S100, obtaining the defect level of the ice surface 200 to be processed;

Step S200, when the defect level of the ice surface 200 to be processed is millimeter level, select the polishing head 100 whose polishing surface particle size is greater than or equal to 30 and less than 800, and when the defect level of the ice surface 200 to be processed is micron level, select polishing head 100. The polishing head 100 with the surface particle size number greater than 800 and less than or equal to 1200;

Step S300 , using the polishing head 100 to polish the ice surface 200 to be processed under the preset pressure and the preset rotational speed.

It should be noted that, when the defect level of the ice surface 200 to be processed is the millimeter level, the particle size number of the polishing surface can be specifically selected according to the actual situation of the ice surface 200 to be processed, such as 30, 100, 300, 500, 800 and other particle sizes; When the defect level of the ice surface 200 to be processed is micron level, the particle size of the polishing surface can be specifically selected according to the actual situation of the ice surface 200 to be processed, for example, the micron level of 800, 900, 1000, 1100, 1200, etc. Wherein, the larger the polishing surface particle size (ie mesh number or number) of the polishing head 100, the smaller and more particles on the square inch of the polishing surface; on the contrary, the polishing surface particle size (ie mesh number or number) of the polishing head 100 The smaller the number), the larger and smaller the particles will be on the square inch of the polished surface. For example, the particle size number 1000# represents a 1000 mesh screen, and the unit is the number of openings on 1 square inch, which corresponds to a diameter of about 14 microns.

As an example, polishing head 100 may be assembled to polishing power unit 300 (see FIG. 2 ). The polishing head 100 can be assembled to the polishing power device 300 by means of Velcro, sewing, gluing, welding, or the like. The polishing power device 300 includes, but is not limited to, a polishing machine, a polishing car, and a waxing machine. The device can polish not only small ice rinks, but also larger ice rinks such as speed skating rinks and curling rinks.

According to the above ice surface polishing method, according to the defect level of the ice surface 200 to be processed, polishing heads 100 with different polishing surface particle sizes can be used to polish it, which can not only ensure the polishing efficiency, but also effectively eliminate the ice of millimeter and smaller scales. Surface defects, avoiding the problem that traditional sandpaper will fail quickly and residual grit on the surface with water, and it is also cheaper than using high-performance steel knives as polishing heads. It has the advantages of low cost, simple operation, and a wide range of defects that can be polished. It has been tested and verified on the ice surface of professional ice rinks, and it can solve the small scratches, pits and other common ice surface. The raised defects are beneficial to the ice surface becoming more beautiful, smooth and safe.

For step S200, when the defect level of the ice surface 200 to be processed is millimeter level, the material of the polishing head 100 is selected from at least one of scouring pads, wire reels, hemp reels, denim fabrics, and miscellaneous fabrics. In addition, the miscellaneous cloth is coarse cloth.

When the defect level of the ice surface 200 to be processed is micron level, the material of the polishing head 100 is selected from at least one of nylon, fiber cloth, flocking, cotton cloth, non-woven fabric, and flannel.

For step S300, during the polishing process, the preset pressure of the polishing head 100 may be set to 10N˜4000N, for example, may be set to 10N, 50N, 100N, 500N, 1000N, 2000N, 4000N, and the like. It can not only ensure that the polishing head 100 is in full contact with the ice surface 200 to be processed, so as to achieve a better polishing effect, but also avoid crushing the ice surface. And, the preset rotational speed of the polishing head 100 can be set to 20 rpm to 5000 rpm, for example, it can be set to 20 rpm, 50 rpm, 100 rpm, 500 rpm, 1000 rpm, 5000 rpm, and the like. In this way, both polishing efficiency and processing stability can be ensured.

During polishing, the polishing time can be set according to the level of ice surface defects. For example, for larger ice surface defects, such as millimeter-level ice grain protrusions, a polishing head 100 with a large particle size, such as a scouring pad with a particle size of 180#, No. 8698, can be used for polishing for 1 s to 120 s. As another example, for small ice surface defects, such as micron-level ice surface depressions, a polishing head 100 with a small roughness, such as nylon and other materials, is used for polishing for 1 s to 120 s, and a surface roughness meter is used to measure the surface roughness before polishing. The final roughness, as shown in Table 1, can also have a good polishing effect on micron-scale ice surface defects.

They have been tested and verified on the ice surface of professional ice rinks, and can solve the common small defects on ice surfaces. Scratches, dents and raised defects help make the ice surface more beautiful, smooth and safe.
