(1) Lub hardness yog siab, feem ntau tsis qis dua qhov nyuaj ntawm cov khoom tiav.
(2) Zoo nruj, tsis yooj yim rau deform thiab hnav vim kev sib tsoo siab.
(3) Kev coj tus kheej kom zoo, uas yog, thaum tsoo los ntawm kev sib tsoo siab, cov seem hauv seem tseem nyob
Ntse polygons.
(4) cov nplaig yaj lossis qhov muag muag yog qhov siab, thiab lub kaum ntse ntse ntawm lub abrasive tsis yooj yim rau yaj los yog hloov raws li kev ua ntawm kev sib tsoo kub.
Mos.
(5) Nws muaj cov tshuaj lom neeg zoo thiab tsis cuam tshuam nrog cov khoom tiav.
(6) Cov duab thiab cov loj me me kuj zoo sib xws, thiab qhov loj me ntawm txhua abrasive yog nyob hauv qee qhov.
Raws li kev faib cov hom tawv, muaj ob hom ntawm super-hard abrasives thiab dog dig abrasives. Cov qhab nia dav dav tuaj yeem faib ua corundum, silicon carbide, pob zeb diamond thiab corundum, uas feem ntau yog siv hauv kev tsim khoom thiab cov xuab zeb ntawm cov cuab yeej dav dav. Lawv yog cov abrasives zoo tib yam, tab sis muaj ntau yam ntawm qib siab ntawm corundum abrasives, xws li zirconium corundum lossis ib leeg siv lead ua corundum. Rau corundum abrasives," xim dub thiab dawb xim av corundum" feem ntau yog siv. Tshwj xeeb tshaj yog thaum tsim cov cuab yeej abrasive thiab sandblasting, qhov nyuaj yuav tsum nruj heev. Yog koj muaj lus nug dab tsi, thov sab laj.
Sandblasting abrasive muaj cov yam ntxwv ntawm lub sijhawm sib tsoo luv luv, kev ua haujlwm siab, kev ua haujlwm zoo thiab tus nqi qis. Cov khoom muaj ntsis hardness, siab toughness, zoo nws tus kheej-ntse, tsis siv xuab zeb tsawg, rov ua dua tshiab thiab siab abrasive tiav; nws muaj cov tshuaj lom neeg ruaj khov, hnav tsis kam, acid thiab alkali tsis kam. Lub plhaub zoo li lub pluaj muaj cov npoo ntse thiab cov khoom sib dhos, tuaj yeem tsim cov npoo tshiab thiab cov pob zeb hauv cov txheej txheem txuas ntxiv hauv kev sib tsoo thiab kev faib tawm, kom lawv lub peev xwm sib tsoo zoo dua li lwm cov abrasives. Hauv tshwj xeeb, nws muaj qhov zoo ntawm siab hardness, siab siab nqus, thaj chaw ruaj khov tshuaj lom neeg thiab cov yam ntxwv ua kom pom tus kheej. Nws tau dhau los ua kev xaiv abrasive hauv cov txheej txheem sandblasting; tib lub sijhawm, nws tseem yog ib qho khoom siv zoo tshaj plaws rau sandblasting thiab xeb tshem tawm ntawm cov khoom ua haujlwm, nrog rau kev sib tsoo thiab polishing.
