For the surface polishing treatment of carbon fiber products, it is recommended that the customer use 240 mesh sandpaper water grinding treatment as the best, without further refinement grinding, which also provides a good adhesion to the subsequent coating.Why use a sandpaper water mill instead of a dry mill?In short, there are two benefits:1. Prevent dry grinding carbon fiber dust from entering the fine holes on the surface of the product, which is extremely hard to clean out, and washing is of no use.If the treatment is not clean, the subsequent direct varnish treatment, then the defect will always be sealed inside.
2. The water mill treatment, carbon fiber dust will not fly everywhere.I believe that the workers who do the polishing process should understand the extent of the harm, it will float into the air, breathe into your lungs, and it will not come out so easily.
