Qhov zoo ntawmdawb fused aluminayog qhov zoo tshaj plaws txiav txim siab los ntawm ib kauj ruam-los ntawm- kev ntsuam xyuas cov kauj ruam es tsis yog los ntawm kev cia siab rau qhov zoo li lossis ib qho kev qhia tshwj xeeb. Kev ntsuas qhov ua tau zoo tuaj yeem muab faib ua qhov kev tshuaj ntsuam thawj zaug ntawm cov khoom siv yooj yim thiab kev txheeb xyuas zaum kawg ntawm kev ua tau zoo- cov yam ntxwv ntsig txog. Txoj hauv kev no pab txiav txim siab seb cov khoom puas tsim nyog rau kev thov abrasive thiab refractory daim ntaub ntawv.
Thawj Qhov Kev Ntsuas Zoo
Thawj kauj ruam yog xyuas cov ntsiab lus ntawm alumina (Al₂O₃). Txij li thaum alumina yog qhov tseem ceeb ntawm cov dawb fused alumina, qhov siab dua thiab ruaj khov Al₂O₃ cov ntsiab lus feem ntau qhia tau zoo dua purity thiab kev ua tau zoo dua qub. Cov ntaub ntawv nrog cov ntsiab lus qis dua alumina tuaj yeem muaj cov impurities ntau dhau thiab yuav tsum tau ua tib zoo soj ntsuam ua ntej siv.
Purity yog lwm qhov taw qhia tseem ceeb. Tsis xav impurities tuaj yeem cuam tshuam qhov hardness, txiav efficiency, xim, thiab tag nrho stability ntawm abrasive. Rau cov ntawv thov uas qhov kev huv huv ntawm qhov chaw thiab kev ua tiav zoo ib yam yog qhov tseem ceeb, siab -purity dawb fused alumina yog qhov tseem ceeb.
Hardness kuj yuav tsum tau txiav txim siab thaum qhov kev ntsuam xyuas thawj zaug. Lub abrasive xav tau txaus hardness kom zoo txiav thiab abrasive workpiece. Yog hais tias lub hardness tsawg dhau lawm, cov nplej yuav hnav ntxov ntxov, txo cov khoom siv tshem tawm thiab ua rau nws nyuaj rau kev ua tiav qhov zoo ib yam.
Kev Ua Haujlwm Kawg
Tom qab cov khoom tseem ceeb ua tau raws li cov qauv xav tau, kev hnav tsis kam yuav tsum raug ntsuas. High- zoo fused alumina zoo tswj nws lub peev xwm txiav thaum lub sijhawm ua haujlwm ntev thiab tuaj yeem txo qis kev siv ntau dhau. Nws txoj kev hnav zoo kuj tseem pab txo cov plua plav, uas muaj txiaj ntsig zoo hauv kev siv xws li sandblasting qhov chaw ua haujlwm huv thiab tsis muaj hlau tsis huv yog qhov tseem ceeb.
Corrosion kuj yog lwm qhov qhia tau zoo, tshwj xeeb tshaj yog thaum cov tshuaj abrasive raug rau cov tshuaj sib txawv los yog xav tau ib puag ncig ua haujlwm. Kev ruaj ntseg tshuaj zoo tso cai rau cov khoom siv los tswj nws cov khoom thiab xa cov txiaj ntsig zoo dua nyob thoob plaws ntau yam kev siv.
Rau daim ntawv thov refractory, refractoriness yuav tsum tau muab rau hauv tus account. Dawb fused alumina siv nyob rau hauv siab - qhov kub thiab txias ib puag ncig yuav tsum tau tiv taus kub kub yam tsis poob nws cov qauv kev ruaj ntseg. Lub zog refractoriness tso cai rau nws kom muaj kev ntseeg tau zoo thaum lub sij hawm tua hluav taws thiab kev pabcuam, ua rau nws tsim nyog rau kev tsim cov khoom zoo tshaj - zoo refractory.
Zuag qhia tag nrho, kev ntsuam xyuas txhim khu kev qha yuav tsum xav txog Al₂O₃ cov ntsiab lus, purity, hardness, hnav tsis kam, corrosion kuj, thiab refractoriness ua ke. Saib ntawm cov khoom no tag nrho muab cov duab tseeb dua ntawm cov khoom siv zoo thiab pab xyuas kom meej tias cov xim dawb fused alumina raug xaiv raws li qhov xav tau ntawm nws daim ntawv thov.
