Dab tsi yog vim li cas rau qhov rov qab ntawm alkali thiab dawb Frost ntawm siab alumina refractory cib?
Kev tsom xam ntawm cov laj thawj yog vim li cas alumina refractory cib siab rov qab mus rau alkali thiab ua hoarfrost yog raws li hauv qab no:
1. Kev cuam tshuam ntawm cov khoom siv raw:High-alumina refractory bricks yuav rov qab mus rau alkali ntawm qhov kub thiab txias vim tias lawv cov ntaub ntawv raw muaj cov ntsev soluble. Cov ntsev no decompose ntawm qhov kub thiab txias thiab tso tawm alkaline oxides. Lawv zoo li "kho kho dej" ntawm cov cib, ua rau koj cov cib zoo nkauj tam sim ntawd ua kom khov. Yog li ntawd, thaum peb xaivsiab alumina cib, peb yuav tsum ua tib zoo xyuas cov ntaub ntawv raw kom tsis txhob raug raided los ntawm cov "kho cov kua"!
2. Kev cuam tshuam ntawm kev tua hluav taws kub:Txoj kev tua hluav taws kub ntawm alumina refractory cib yog qhov tseem ceeb heev. Yog hais tias qhov kub tsis siab txaus los yog lub sij hawm tsis ntev txaus, qee cov ntsev soluble yuav tsis decomposed kiag li. Cov "cov ntsiab lus tawv tawv" no yuav nyob hauv lub cib, thiab tom qab ntawd maj mam cais tawm thaum siv tom qab, ua rau tsis kaj siab dawb te. Yog li ntawd, txhawm rau tiv thaiv qhov tshwm sim ntawm hoarfrost, peb yuav tsum tswj xyuas qhov kub thiab txias thiab lub sij hawm kom paub tseeb tias tag nrho cov ntsev ntsev tuaj yeem decomposed tag nrho. Nyob rau hauv txoj kev no, peb cov high-alumina refractory cib tuaj yeem nyob twj ywm zoo nkauj thiab siv tau!
3. Cov nyhuv ntawm noo noo: Thaum lub sij hawm kev thauj mus los, cia thiab siv cov alumina refractory cib siab, yuav tsum tau saib xyuas tshwj xeeb kom tsis txhob muaj dej noo, tshwj xeeb tshaj yog cov dej uas muaj ntsev. Cov dej "ntses" cov dej molecules yuav sau rau ntawm qhov chaw ntawm lub cib thiab hnov mob nrog cov alkaline tshuaj nyob rau hauv cib los ua dawb te. Qhov no zoo li muab lub tsho "dawb" rau ntawm Cib, ua rau nws poob nws qhov ntxim nyiam qub. Yog li ntawd, txhawm rau tswj kev zoo nkauj thiab kev ua haujlwm ntawm high-alumina refractory bricks, peb yuav tsum tau ceev faj txog nws!
4. Kev cuam tshuam ntawm huab cua: Cov cua hauv qhov cub yog "kev tswj lub siab" ntawm siab alumina refractory cib. Yog tias huab cua "zoo siab" thiab oxidizing huab cua hnyav dhau, qee cov khoom hauv lub cib yuav "txaus ntshai" thiab raug oxidation tshwm sim. Qhov no zoo li "tshuaj riot" nyob rau hauv lub cib, ua alkaline oxides. Cov oxides no yuav khaws cia rau saum npoo ntawm cov cib, ua rau alkalinization. Yog li ntawd, txhawm rau tswj kev ua haujlwm ruaj khov ntawm high-alumina refractory cib, peb yuav tsum kawm tswj cov cua hauv qhov cub kom nws mos thiab qab ntxiag!
