Feem ntau siv corundum abrasive hauv kev lag luam abrasive yogdawb aluminium oxide. Nws yog ib qho khoom siv tseem ceeb hauv kev ua lag luam thiab tsim nyog rau kev kho kom zoo nkauj ntawm ntau yam khoom siab- kawg, khoom siv tes ua, lossis khoom kho vajtse. Tom qab sandblasting, nto yog dawb thiab tsis muaj impurities, tshem tawm cov hassle ntawm tu.
Yuav ua li cas ua kom dawb aluminium oxide waterproof thiab ya raws - pov thawj?
Dawb aluminium oxide yog siv dav hauv kev tsim cov ceramics, resin-bonded abrasives, thiab hauv kev sib tsoo, polishing, sandblasting, thiab precision casting. Nws kuj tseem siv rau hauv kev tsim cov khoom siv qib siab - qib refractory. Yog li, yuav ua li cas dawb aluminium oxide yuav tsum tsis muaj dej thiab khaws cia hauv huab cua ntub?
Feem ntau, cov tshuaj tiv thaiv dej tuaj yeem siv los ua cov dej tsis muaj dej dawb aluminium oxide. Cov neeg ua haujlwm no, ua kom haum rau cov khoom sib txawv, muab kev tiv thaiv zoo tiv thaiv kev nkag mus ntawm dej, stains, thiab roj, thiab tseem tiv thaiv cov ntxhia ntsev los ntawm kev nqa tawm ntawm pob zeb, ua rau efflorescence lossis xeb.
Cov dej stains yog qhov teeb meem feem ntau thiab tsis tuaj yeem zam nrog dawb aluminium oxide. Nyob rau hauv ib txwm muaj xwm txheej, cov dej stains yuav ploj mus dhau sijhawm. Txawm li cas los xij, nyob rau hauv qhov kub siab ntawm cov dej hiav txwv, cov dej stains yuav tsis ploj. Thaum lub sij hawm ntev - khaws cia, cov tshuaj lawv tus kheej (tshwj tsis yog kua) tsis cuam tshuam rau pob zeb. Tsuas yog thaum cov khoom nkag mus rau hauv kev sib cuag nrog dej, cov tshuaj hloov pauv tshwm sim, uas ua rau muaj cov waxy txheej. Yog li ntawd, nws tuaj yeem txiav txim siab tias dej yog tus yeeb ncuab loj tshaj plaws ntawm lub pob zeb, thiab tib txoj kev daws teeb meem yog los thaiv cov pores ntawm pob zeb.
