Kev ua haujlwm ntawm kev siv cov cua compressed ua lub zog los thawb cov abrasives rau saum npoo ntawm lub workpiece rau kev kho mob hu ua sandblasting, uas yog qhov peb feem ntau hu ua txhaj tshuaj peening thiab tua peening.
Brown aluminium oxidevim hais tias nyob rau hauv thaum ntxov hnub ntawm kev txhaj tshuaj blasting tshuab, xuab zeb tsuas yog abrasive uas yuav siv tau. Yog li ntawd, thaum lub sij hawm ntawd thiab ntev tom qab ntawd, kev txhaj tshuaj blasting yeej ib txwm hu ua sandblasting. Ntawm ntau txoj kev kho saum npoo av, sandblasting (steev blasting) muaj cov txiaj ntsig zoo tshaj plaws, kev hloov kho tau zoo tshaj plaws, thiab kev siv dav tshaj plaws; nws ntxuav cov hlau nto sai tshaj plaws thiab zoo tshaj plaws. Sandblasting tuaj yeem ntxuav qhov chaw uas feem ntau nyuaj los ntxuav. Qee cov cuab yeej tshwj xeeb tuaj yeem siv los ntxuav cov kav dej sab hauv. Sandblasting yog tus nqi qis tshaj. Sandblasting tuaj yeem ua tiav qhov yuav tsum tau ua kom huv si thiab qee qhov roughness ntawm qhov chaw yuav tsum tau ntxuav tib lub sijhawm, thiab txhim kho cov adhesion ntawm cov txheej txheem ntawm cov txheej txheem. Txawm tias cov xim zoo npaum li cas, nws tsis tuaj yeem ua raws li qhov chaw ntawm lub workpiece yam tsis muaj kev kho deg rau lub sijhawm ntev. Lub hom phiaj ntawm kev kho deg yog los ntxuav qhov chaw thiab tsim cov roughness ntawm qhov chaw yuav tsum tau "xauv" txheej.
Tom qab lub npoo ntawm sandblasted workpiece yog coated nrog ib tug muaj txheej txheej nrog kev ua tau zoo, lub neej txheej yuav ua tau ntau tshaj li 3.5 npaug ntawm cov zoo tib yam txheej rau ntawm qhov chaw kho los ntawm lwm txoj kev. Lwm qhov zoo ntawm sandblasting (tshuaj tua moj tej tawg tu) yog qhov roughness ntawm qhov chaw tuaj yeem txiav txim siab ua ntej raws li qhov yuav tsum tau ua thiab tuaj yeem ua tiav tau yooj yim thaum lub sijhawm ntxuav.
Qhov tshwj xeebxim av aluminium oxideabrasive rau sandblasting muaj nruab nrab hardness, siab packing ceev, tsis muaj dawb silica, loj lub ntiajteb txawj nqus thiab zoo toughness. Brown aluminium oxide yog ib qho zoo tagnrho "ib puag ncig tus phooj ywg" sandblasting khoom, dav siv nyob rau hauv txhuas profiles, tooj liab profile iav, ntxuav denim precision pwm thiab lwm yam teb.
