Dab tsi yog cov kev daws teeb meem ntawm high alumina hluav taws cib rov qab rau alkali thiab hoarfrost?
Nws yog ib qho teeb meem tshwm sim uas siab alumina hluav taws cib rov qab mus rau alkali thiab ua frosty. Yog li yuav daws qhov teeb meem no li cas? Topower refractory cov neeg ua haujlwm yuav muab cov kev daws teeb meem rau koj siv:
1. nruj me ntsis tswj cov ntaub ntawv raw:Txhawm rau kom ntseeg tau tias kev ua haujlwm zoo heev ntawmsiab alumina cib, peb yuav tsum xaiv cov khoom siv raw nrog siab purity thiab tsis txhob siv cov khoom siv raw uas muaj cov ntsev soluble. Xyuas kom muaj kev ntseeg siab ntawm nws qhov zoo los ntawm qhov chaw. Nyob rau tib lub sijhawm, kev soj ntsuam nruj nruj yog ua los ntawm cov khoom siv raw kom ntseeg tau tias lawv ua tau raws li cov qauv tsim nyog. Qhov no zoo li "kev kuaj xyuas lub cev" ntawm cib kom paub tseeb tias lawv muaj kev noj qab haus huv "lub cev".
2. Txhim kho cov txheej txheem tua hluav taws: Txhawm rau kom ntseeg tau tias qhov ua tau zoo ntawm cov hluav taws kub alumina siab, peb yuav tsum tau tswj xyuas qhov kub thiab lub sijhawm kom raug thaum lub sijhawm tua hluav taws. Tsim kom muaj qhov kub thiab txias thiab ncua sij hawm tua hluav taws tuaj yeem txhawb kev ua kom tiav ntawm cov ntsev soluble thiab tsis txhob muaj teeb meem te tom qab. Nyob rau tib lub sijhawm, peb kuj yuav tsum tau ua tib zoo saib xyuas kev tswj hwm ntawm qhov chaw tua hluav taws kom tsis txhob muaj oxidation ntau dhau. Ib qho chaw oxidizing ntau dhau yuav ua rau cov tawv nqaij tawv. Yog li ntawd, tsuas yog thaum qhov kub thiab txias, lub sijhawm thiab huab cua raug tswj kom raug, peb tuaj yeem ua kom zoo zoo alumina refractory cib, ua rau lawv ib txwm ruaj khov thiab ua haujlwm tau zoo!
3. Txhim kho kev khaws cia thiab kev tswj xyuas kev thauj mus los: Txhawm rau kom ntseeg tau tias qhov kev ua tau zoo thiab cov tsos ntawm cov hluav taws kub alumina siab, peb yuav tsum tau them nyiaj tshwj xeeb rau cov av noo ib puag ncig thaum khaws cia thiab kev thauj mus los. Tsis txhob sib cuag nrog cov dej noo thiab ntsev thiab ua kom ib puag ncig qhuav. Qhov no yog qhov yooj yim tshaj plaws kev saib xyuas rau siab alumina refractory cib. Thaum tsim nyog, peb tseem yuav muab tso rau hauv lub kaw lus "tiv thaiv" kom ntseeg tau tias nws tsis cuam tshuam los ntawm ib puag ncig sab nraud.
4. Pretreatment ua ntej siv:Ua ntej siv high alumina hluav taws cib, txhawm rau kom ntseeg tau tias lawv qhov kev ua tau zoo tshaj plaws, peb yuav tsum tau kho lawv. Los ntawm txoj kev kho ua ntej xws li ziab thiab ziab huab cua, peb tuaj yeem tshem tawm cov dej noo thiab ntsev uas txuas rau saum npoo ntawm cib. Nyob rau hauv txoj kev no, lub siab-alumina refractory cib tuaj yeem muab tso rau hauv qhov zoo tshaj plaws, uas qhia lawv qhov kev ua tau zoo super hluav taws kub!
5. Kev saib xyuas tsis tu ncua:Txhawm rau kom ntseeg tau tias lub sijhawm ua haujlwm ruaj khov ntawm siab alumina refractory cib, peb yuav tsum tsis tu ncua xyuas cov cuab yeej tswj cua hauv qhov cub. Muab cov kev pabcuam tu tsis tu ncua rau siab alumina refractory cib thiab ua cov kev kuaj xyuas lub cev. Nyob rau hauv txoj kev no, peb lub siab alumina hluav taws cib tuaj yeem nyob hauv qhov zoo tshaj plaws!
