Sandpaper los ntawm ob cov ntaub ntawv: aluminium oxide thiab silicon carbide. Aluminium oxide yog ruaj khov thiab haum rau kev ua haujlwm ntxhib, xws li pib xuab zeb ntawm phab ntsa thiab cov rooj tog loj. Silicon carbide yog hnav- tiv taus thiab ntse, haum rau kev ua haujlwm zoo, xws li cov xuab zeb zoo ntawm cov ntoo thiab polishing ntawm cov ntaub ntawv hlau.
2. Xaiv los ntawm Grit Loj
Grit loj sawv cev rau qhov zoo ntawm cov ntawv xuab zeb. Ib qho me me me me txhais tau hais tias coarser hais, sai sanding ceev, tab sis ib tug me ntsis rougher nto; ib tug loj grit loj txhais tau hais tias finer hais, ua rau ib tug super du nto. Yuav xaiv li cas?
