There is a big difference between sanding paper for putty grinder and manual sanding paper. Sanding paper for grinder needs to be pasted on the back, so that it can be firmly fixed on the sanding plate. Therefore, sanding paper for wall sanding machine is flocked on the back. Secondly, due to the high power and speed of the grinder, the abrasion resistance of the sandpaper is required to be high, so the strength of the sandpaper used in the grinder is high and it is wear-resistant. One piece of sandpaper should be 6 pieces for manual sandpaper.
But in addition, one point that may be ignored by the constructor is how to choose the thickness of sandpaper for the mill, that is, the grade. Because of the straight-line movement of hand grinding back and forth, the traces left by sandpaper are obvious. The head of the surface grinder is a high-speed rotating motion mode, and the ground wall surface has high flatness and is not easy to leave scratches on the wall surface. For this reason, the grade of the selected sandpaper can be smaller than that of the manual sandpaper (that is, it is thicker than that of the manual sandpaper). If 240 × sandpaper is used for manual grinding, 180 × sandpaper can be used for the grinder, which can not only achieve the same smooth effect, but also has high grinding efficiency.
We all know that after the wall paint is applied, in order to ensure the smoothness and flatness of the surface, we will polish it. At this time, we need to use a wall grinder. In order to ensure its smooth operation, we need to operate according to the relevant regulations. Before starting the machine, we need to attach the grinding plate to the wall. When polishing the upper part of the wall, we need to operate the machine to move up and down, and pay attention to keep it uniform during the up and down movement Speed, do not stop when turning, so as to avoid sand marks on the wall. Secondly, when grinding the lower part of the wall, pay attention to keep the balance of the grinding plate when moving under the foot. When grinding, work in order to avoid missing, and pay attention to the working state of the machine at any time when grinding the equipment. If there are problems, they should be solved in time. Some special places need to be repaired manually to avoid the machine There is a phenomenon of bottoming during the grinding of the equipment. After the grinding, please stop the equipment and clean it for the next use.
