Abrasive blasting, feem ntau hu ua sandblasting, yog kev ua haujlwm ntawm forcibly propelling cov kwj ntawm cov abrasive cov khoom tiv thaiv ib qho chaw hauv qab ntawm qhov siab kom ua qhov chaw du, roughen ib qhov chaw du, zoo li thaj chaw lossis tshem tawm cov khoom tsis huv. Cov kua txau ua pa, feem ntau ua kom cua, lossis cov log tsheb sib npaug yog siv los txhawb cov khoom tawg (feem ntau hu ua xov xwm). Muaj ntau ntau yam kev sib txawv ntawm cov txheej txheem, siv ntau yam xov xwm; ib co yog cov ua muaj zog heev, hos lwm cov mas me dua. Qhov kev phom sij ntau yog tua blasting (nrog hlau txhaj) thiab sandblasting (nrog xuab zeb). Cov kab nrib me me sib xyaw ua ke xws li iav hlaws blasting (nrog iav hlaws) thiab xov xwm blasting nrog av-up yas Tshuag lossis Walnut shells thiab pob kws. Daim ntawv sib hais me me yog qhov dej siab (nrog ci dej qab zib). Ntxiv rau, muaj lwm txoj kev xaiv uas nyuam qhuav abrasive los yog nonabrasive, xws li dej khov thiab blasting dej khov.
Qhov kev thov nce zuj zus rau cov khoom siv xuab zeb blasting tsav lub khw. Kev nce qib ua haujlwm, mob ntsws zoo li silicosis tshwm sim los ntawm phau ntawv xuab zeb blasting kev ua haujlwm thiab kev lag luam nrawm yog qhov tseem ceeb tsav rau cov xuab zeb blasting cov khoom lag luam. Hloov chaw ntawm phau ntawv ua haujlwm txhim kho kev ua tau zoo thiab ua haujlwm. Kev nqus tau ntawm silica, uas ib txwm siv los ua cov khoom siv ntxiag hauv cov tshuab xuab zeb blasting, ua rau muaj kev phom sij xws li silicosis thiab lwm yam kab mob ntsws. Cov khoom siv xuab zeb blasting kev tiv thaiv kev cog lus rau cov kev mob ntsws tsis zoo, uas yog qhov xav tias yuav dhau mus ua lag luam loj hlob. Cov teb chaws Esxias Pacific sandblasting tshuab ua lag luam loj tsaj vim cov nqi qis thiab kev thov siab rau cov khoom no. Tuam Tshoj tau kwv yees hais tias yog tus xa nyiaj loj rau APAC. Teb chaws Europe sandblasting tshuab lag luam loj li kev xav tau yuav nce dhau ntawm lub sijhawm kwv yees, ua raws li los ntawm North America.
