Qhov saum npoo yuav dawb tom qab sandblasting. Tsis muaj impurities, tsis tas yuav txhawj txog kev tu.
Dawb aluminium oxide hmoov yog ib qho nyuaj thiab nkig tshaj xim av corundum, thiab muaj zog txiav zog. Zoo tshuaj stability thiab zoo rwb thaiv tsev zog. Nws tuaj yeem siv los ua cov qauv tsim thiab coated abrasives, ntub dej lossis qhuav xuab zeb, haum rau ultra-precision sib tsoo thiab polishing hauv cov khoom siv lead ua thiab hluav taws xob thiab kev tsim cov khoom siv refractory siab heev; haum rau kev ua quenched steel, alloy steel, high-speed steel, high-carbon steel, thiab lwm yam. Ib yam khoom uas nyuaj thiab muaj zog tensile ntau dua. Dawb corundum yog ua los ntawm cov zoo txhuas oxide hmoov ua raw khoom thiab yog refined thiab crystallized los ntawm hluav taws xob fusion. Nws muaj purity siab, zoo nws tus kheej-sharpening zog, acid thiab alkali corrosion kuj, kub tsis kam, ruaj thermal kev ua tau zoo, thiab nws hardness yog me ntsis siab dua xim av corundum.
Tom qab txuas ntxiv kev txhim kho thiab kev sim ua lag luam, cov hmoov dawb txhuas oxide micro hmoov tau lees paub los ntawm cov neeg siv khoom. Dawb fused alumina muaj siab hardness, zoo tus kheej-sharpening zog, thiab zoo heev sib tsoo thiab polishing zog. Nyob rau tib lub sijhawm, tom qab kev txhim kho thev naus laus zis, tus nqi tsim khoom tau txo qis me ntsis. Nyob rau hauv cov ntaub ntawv ntawm dawb corundum, cov txheej txheem electrofusion yog nyuaj los ntawm cov tshuaj tiv thaiv, homogeneous polycrystalline transformation, recrystallization, thiab co-solution, tab sis nws yog tsuas yog ua tiav los ntawm qhov loj deg cheeb tsam thiab siab nto zog ntawm cov hmoov. Thaum lub sij hawm npaj cov hmoov, ntau yam lattice defects tshwm nyob rau ntawm nws nto thiab sab hauv.
Dawb fused alumina yog ua los ntawm cov khoom zoo aluminium oxide hmoov ua raw khoom thiab yog refined thiab crystallized los ntawm hluav taws xob fusion. Nws muaj purity siab, zoo tus kheej-sharpening zog, acid thiab alkali corrosion kuj, kub tsis kam, thiab ruaj khov thermal zog; nws hardness yog me ntsis siab dua xim av corundum, thiab nws toughness yog me ntsis qis. Nws muaj zog sib tsoo muaj peev xwm, tsis tshua muaj nqi calorific thiab high efficiency; Nws tuaj yeem siv los ua cov cuab yeej sib tsoo, uas tuaj yeem siv rau kev sib tsoo zoo-grained abrasives xws li high-carbon steel, high-speed steel thiab stainless hlau, thiab tseem tuaj yeem siv rau precision casting thiab cov khoom siv refractory siab heev.
Dawb aluminium oxide hmoov muaj tshuaj lom neeg ruaj khov thiab zoo rwb thaiv tsev. Dawb corundum yog ib qho nyuaj thiab nkig ntau dua li xim av corundum thiab muaj zog txiav zog. Nws tuaj yeem siv rau cov khoom siv thiab coated abrasives. Nws tuaj yeem siv rau ntub lossis qhuav xuab zeb blasting. Nws yog tsim rau siv lead ua thiab hluav taws xob kev lag luam. Super precision sib tsoo thiab polishing thiab tsim cov ntaub ntawv siab heev refractory, thiab lwm yam, haum rau kev ua cov hlau tsis muaj steel, alloy steel, high-speed steel, high-carbon steel thiab lwm yam ntaub ntawv nrog hardness thiab siab tensile zog. Dawb corundum abrasive kuj tseem siv tau los ua kev sib cuag xov xwm, insulators thiab Precision casting xuab zeb, thiab lwm yam.
Dawb aluminium oxide micropowder tsis cuam tshuam rau cov xim ntawm lub workpiece thiab tuaj yeem siv rau sandblasting nyob rau hauv cov txheej txheem uas hlau hmoov residue yog nruj me ntsis txwv tsis pub. Lub micron hmoov qib yog tsim nyog rau ntub sandblasting thiab polishing hauj lwm. Nws muaj kev ua haujlwm ceev ceev thiab zoo, thiab muaj cov hlau oxide tsawg heev. Nws yog qhov tsim nyog Sandblasting ua haujlwm rau cov hlau seem.
Kev npaj ib txwm ua ntawm dawb fused alumina micro hmoov yog kom smelt cov ntaub ntawv raw ntawm qhov kub thiab txias hauv hluav taws xob arc rauv. Cov dawb corundum blocks tau ua tiav, finely crushed, thiab hydraulically muab faib ua dawb corundum micro hmoov ntawm ntau qhov sib txawv. Niaj hnub no, dawb fused alumina micro hmoov yog tsim. , uas yog, sintered dawb txhuas oxide hmoov, yog tsim los ntawm molding powdery raw cov ntaub ntawv thiab cua sov lawv ntawm ib tug kub qis dua lawv melting point, thiaj li hais tias lawv adhere, daim ntawv cog lus, fuse, recrystallize, thiab lwm yam rau ib leeg nyob rau hauv qhov kev txiav txim ntawm additives. , thiab yog sintered densely thiab muaj cov khoom tshwj xeeb. kev ua tau zoo.
