Polishing is a surface treatment process that uses methods such as polishing and polishing to make the surface of an object smooth and shiny. During the polishing process, sandpaper is an important tool that can remove burrs, defects, etc. from the surface of an object, making it smoother. However, if sandpaper is not used correctly during polishing, sandpaper marks can easily occur.


Sandpaper imprinting is usually caused by the use of too thick sandpaper during polishing or failure to follow the correct steps, resulting in sandpaper particles being engraved on the surface of the object, forming a mark that is difficult to remove. In addition, if the pressure of the sandpaper during polishing is too high or the quality of the sandpaper used is poor, it is also easy to produce sandpaper marks.


To avoid sandpaper printing, the following points need to be noted:


one


Choose a suitable sandpaper and choose the corresponding sandpaper particle size according to the polishing needs.


two


When polishing, follow the correct steps. First, use coarser sandpaper for preliminary polishing, and then gradually use sandpaper with finer particles for detailed polishing.


three


When polishing, maintain a certain pressure and speed, and do not use excessive force to prevent sandpaper particles from being engraved on the surface of the object.


four


After polishing, clean it with a clean cloth or cotton yarn to avoid leaving sandpaper particles or polishing agent residue.




In short, attention should be paid to details when polishing, and the correct use of sandpaper can avoid the generation of sandpaper marks, making the surface of the object smooth and bright.
