Vim lub functional zoo ntawmdawb aluminium oxide, xws li siab hardness, zoo toughness, siab lub ntiajteb txawj nqus, thiab tsis muaj teeb meem tshuaj, dawb corundum yog ib tug environmentally friendly sib tsoo khoom, uas plays lub luag hauj lwm tseem ceeb nyob rau hauv cov tshuaj tsuag sib tsoo thiab tu txoj hauj lwm. Tab sis ntxiv rau dawb corundum, xim av corundum, ntsuab silicon carbide thiab lwm yam abrades feem ntau yog siv los tshuaj tsuag kev kho mob, yog li ntawd.Dab tsi yog qhov tseem ceeb ntawm cov dawb aluminium oxide piv rau lawv?Tsis tas li ntawd, ntau npaum li cas ntawm cov iav hlaws thiab dawb corundum siv hauv sandblasting?
Nws tau nkag siab tias cov corundum dawb siv los ua qhov sib tsoo nruab nrab tam sim no suav txog 45 feem pua ntawm tag nrho cov kev lag luam. Feem ntau siv los ua ib qho kev sib tsoo nruab nrab rau dawb corundum, cov neeg xav kom dawb corundum yog tsim los ntawm hlau txhuas garnet, vim hais tias hlau txhuas garnet muaj qhov sib txawv ntawm cov ntsiab lus molecules, kom tau raws li qhov yuav tsum tau ntawm kev ua hauj lwm hardness. Nyob rau hauv ntau yam tshuaj abrasive, qhov zoo ntawm corundum dawb yog cov hauv qab no:
Ua ntej, cov hmoov av tsawg heev
Qhov khoom siv tau zoo dua, qhov xav tau ntau dua, qhov hloov pauv ntau dua rau cov khoom lag luam, qhov ze dua qhov hloov pauv, qhov xav tau ntau dua elasticity, vim tias cov khoom hloov pauv ntau dua, ua rau cov nqi siab dua, cov neeg siv khoom yuav yuav lwm yam khoom, rau cov khoom siv feem ntau, thaum cov khoom nyob rau ntawm tus nqi siab, kev muag khoom yuav nce ntxiv.
Dawb aluminium oxideyog siv rau sab nraud txau kev sib tsoo kev kho mob, vim hais tias nws lub ntiajteb txawj nqus tshwj xeeb yog qhov siab, yog li cov hmoov av tsawg dua thaum lub sij hawm tshuaj tsuag. Qhov no ua kom tus neeg teb xov tooj noj qab haus huv thiab txhim kho cov neeg ua haujlwm pom kev. Piv nrog rau slag (slag tsim txheej txheem yog dej txias los yog txawm seawater rau kub txias, yog li tsim ib tug iav theem qauv, nrog brittle), vim hais tias cov slag yog kuj nkig, nyob rau hauv cov tshuaj tsuag sib tsoo txheej txheem, yooj yim rau smashed rau daim ntawv. me me hais. Vim hais tias qhov kev faib ua feem ntawm slag yog me me, tsim ntawm me me slag hais raug tshem tawm nyob rau hauv cov huab cua, tsim ntawm ib puag ncig muaj kuab paug. Ib yam li ntawd, quartz xuab zeb kuj yog ib qho yooj yim abrasive.
thib ob. Kev ua tau zoo
Dawb aluminium oxide, nyob rau hauv ib qho kev siab, tuaj yeem tsoo lub ntsej muag ntawm cov khoom nrog cov npoo ntse, yog li nws raug suav tias yog txoj kev sib tsoo ceev heev. Lub acceleration thiab tshaj tawm ntawm cov khoom nyob rau hauv cov huab cua ntws yog cov teebmeem ntawm dawb corundum inertia thiab particle loj. Qhov me me, qhov nrawm nrawm dua, qhov siab dua qhov cuam tshuam ntawm qhov khoom ntawm qhov chaw, ua rau muaj kev tu siab heev - feem ntau, qhov ceev no (m2 / hr) yog ob zaug nrawm dua li lwm cov pa abrasives.
Thib peb, qhov sib faib ntawm sandblasting iav hlaws thiab dawb txhuas oxide
Txog 4: 1 (Ua ntej los yog raws li koj tus kheej kev tshawb fawb ntawm cov degree ntawm matte tsos, siv cov iav pellets kom huv si rau 1: 1 feem ntawm txoj kev muaj cov neeg siv khoom); Qhov tsawg dua dawb corundum, qhov zoo dua cov nyhuv matte, ntxiv qee qhov dawb corundum los yog xav txhim kho kev ua haujlwm ntawm kev txhaj tshuaj peening, ua ke sai dua los ntxuav cov khawb me ntsis ntawm cov hlau tsis huv. Yog tias nws yog chav dej sandblasting, cov xuab zeb yog li ntawm 75-125kg; Raws li qhov kev faib ua feem ntawm thawj zaug mus koom rau hauv cov ntsiav tshuaj iav, nyob rau hauv tus naj npawb ntawm lub sij hawm mus koom nyob rau hauv lub dawb corundum, yog li nws yog yooj yim los tswj cov tsos ntawm matte nyhuv.
