Space film is a special material with high hardness and corrosion resistance, so some special methods need to be adopted during the polishing process. Here are some tips for polishing space flakes, based on the advice of the pros.
Make sure to use the appropriate abrasive. After hand-grinding, space flakes need to be finely ground into powders, commonly used materials such as silicon carbide and aluminum oxide. The particles of these abrasives need to be fine enough and the appropriate particle size selected to ensure that the required smoothness and finish are achieved.
The space piece should be thoroughly cleaned before polishing. Surfaces can be cleaned using detergent and warm water to remove any dust, dirt or grease. When cleaning, be sure to keep your hands clean and avoid using corrosive chemicals to prevent damage to the space film.
Next, place the space piece on a stable workbench and lightly sand the surface with sandpaper or a fine grinder. You can start with larger-grained sandpaper to remove more obvious marks and scratches on the surface. Then gradually sand with finer-grained sandpaper until you achieve the desired finish.
Keep your hands stable during the grinding process and pay attention to applying force evenly. Avoid excessive grinding or excessive force to avoid damaging the surface of the space piece. Surface details can be observed with the help of a magnifying glass or microscope to ensure that the desired effect is achieved.
When the surface smoothness is satisfactory, polishing can begin. First, select a suitable polishing paste or liquid and apply it on the surface of the space piece. Then use a soft cloth or sponge to gently rub the polish evenly over the surface.
Be careful and persistent when polishing to ensure that the entire surface is polished evenly. Better results can be achieved by repeatedly wiping and rotating the space piece. At the same time, be careful not to use excessive force to avoid friction or scratches.
After completion of polishing, the surface of the space wafer should be thoroughly cleaned to remove residual polishing paste and impurities. It can be cleaned with detergent and warm water and wiped with a clean cloth or paper towel. Finally, make sure the space piece is completely dry to prevent water stains from remaining on the surface.
To summarize, the polishing process after hand grinding of space films requires the use of appropriate abrasives, thorough cleaning of the surface, gradual polishing until the smoothness is satisfactory, and the use of appropriate polishing paste for final polishing. During the entire process, keep your hands steady, apply force evenly, and be careful to avoid excessive grinding and excessive force. When finished, clean the surface of the space piece thoroughly and make sure it is completely dry. Hope the above suggestions are helpful to you.
