1: Tsis muaj kev cuam tshuam cov xim ntawm lub workpiece
2: Nws tuaj yeem siv rau sandblasting hauv cov txheej txheem txwv tsis pub cov hmoov hlau tsis zoo
3: Micro-hmoov qib yog qhov zoo tshaj plaws rau kev tua cov blasting thiab ua haujlwm polishing
4: Kev ceev nrawm nrawm thiab zoo heev
5: Tus nqi ntawm cov hlau oxide muaj tsawg kawg, uas tsim nyog rau cov xuab zeb blasting kev ua haujlwm qhov chaw cov hlau tsis zoo.
6: Tom qab pickling kauj ruam mus tshem tawm impurities, lub purity ntawm alumina yog siab
