Hauv qhov teb ntawm nruas hom tua blasting tshuab cuab yeej, qhov tseem ceeb tshaj plaws yog tua blasting thiab xuab zeb blasting. Kev tua blasting feem ntau hais txog kev tua blasting tshuab, thaum xuab zeb blasting mas yog hais txog cov khoom xuab zeb blasting. Cov hauv qab no yuav qhia koj txog qhov sib txawv ntawm kev txhaj tshuaj tag thiab xuab zeb blasting.
Blasting blasting yog lub npe ntawm cov txheej txheem kho tshuab saum npoo av. Nws lub hauv paus ntsiab lus yog tias lub cev muaj zog lub cev ua rau lub cev ua haujlwm tig. Los ntawm qhov kev txiav txim ntawm lub zog centrifugal, qee qhov ntawm txoj kab uas hla ntawm qhov projectile raug pov tseg rau qhov chaw ntawm lub workpiece, kom lub ntsej muag ntawm qhov chaw ua haujlwm mus txog qee qhov kev ua kom tawv. Txhim kho lub neej kev pab cuam ntawm workpiece.
Sandblasting (sanding) yog ib hom haujlwm ntawm kev siv cov huab cua uas siv lub zog ua rau lub zog los thawb lub abrasive rau saum npoo ntawm haujlwm. Tshwj xeeb, nws siv lub tshuab cua nrawm, qhov dej siab rau lub siab, dej khov, thiab lwm yam kom txhawm rau txhawm rau txhawm rau nqus dej kom ntxuav, ua kom lub zog, txiav thiab ua kom lub ntsej muag ua haujlwm. Sandblasting muaj ntau nyob rau hauv cov txheej txheem ntawm kev hloov nws cov duab lossis lub xeev, tab sis cov txheej txheem no tau qeeb heev thiab tsis yooj yim pom.
Lub hom phiaj ntawm txhaj koob tshuaj tiv thaiv blasting thiab xuab zeb blasting ntawm lub workpiece yog los npaj rau qhov kev txiav txim tom ntej, tsis yog tsuas yog xyuas kom muaj qhov ntxhib xav tau ntawm cov txheej txheem tom ntej, tab sis kuj xyuas kom meej tias lub workpiece zoo li niaj hnub zoo li sai tau hauv kev kho saum npoo, thiab txhaj koob tshuaj tivthaiv peening muaj qhov ua tau zoo ntawm cov haujlwm, thiab nws cov txiaj ntsig Ntau dua pom tseeb, kuj hais lus, sandblasting tsis pom tseeb. Feem ntau, txhaj tshuaj tag yog lub pob steel me, thiab xuab zeb blasting yog quartz xuab zeb. Sandblasting yog qhov kev ua haujlwm zoo tshaj plaws, thiab kev tua phom tua yog ntau dua thiab ib nrab tsis siv neeg; tshuaj txau yog ua raws huab cua compressed raws li lub zog rau tshuaj tsuag cov xuab zeb lossis pellets mus rau saum npoo ntawm cov khoom kom ua tiav kev nyab xeeb thiab qee qhov kev ntxhib. Qhov kev ntuav tawm yog txoj kev ntawm centrifugal quab yuam tsim thaum lub pellet tig ntawm qhov kev kub ceev, cuam tshuam rau cov khoom saum npoo kom ua tiav kev tshem tawm thiab qee yam kev ntxhib; seb nws tua blasting lossis xuab zeb blasting, lub workpiece tuaj yeem ntxuav thiab tsis ua haujlwm.
