Ntau txoj hauv kev ntawm hydration kuj ntawm high magnesia-calcium refractory feem ntau yog npaj rau raw cov ntaub ntawv, uas yog magnesia-calcium xuab zeb los yog dolomite xuab zeb, xws li: ntxiv additives, ob-kauj ruam forging thiab hais txog. Cov txheej txheem no tsuas tuaj yeem ncua sijhawm hydration ntawm magnesium-calcium refractory cov ntaub ntawv, tab sis tsis tuaj yeem daws qhov teeb meem hydration, uas kuj yog ib qho teeb meem uas muaj teeb meem rau cov kws tshawb fawb hauv tsev thiab txawv teb chaws tau ntau xyoo.
Rau lub cib nws tus kheej, txhawm rau txhim kho cov dej tsis kam, kev ua haujlwm siab kub thiab slag yaig thiab nkag mus tsis kam thiab stripping kuj ntawmmagnesia dolomite cibyuav tsum pib los ntawm cov txheej txheem cib, ntawm ntau yam cuam tshuam rau cov txheej txheem cib, nws yog ib qho tsim nyog yuav tsum ua kom zoo rau cov txheej txheem npaj xws li particle grading, mixing, molding and firing. Txhawm rau txhim kho kev ua tau zoo ntawm magnesium-calcium cib, kev tshawb fawb ntxaws ntxiv tuaj yeem ua tiav los ntawm cov khoom siv ntxiv thiab cov khoom sib xyaw matrix tom qab cov txheej txheem thev naus laus zis tau txiav txim siab.
1. Cov txheej txheem ntau lawm ntawm magnesia dolomite cib
Tag nrho cov txheej txheem ntawm cov khoom siv refractory suav nrog cov qauv tsim, kev npaj av nkos, molding, ziab thiab kho cua sov, tua hluav taws thiab tom qab ua tiav, tab sis tsis yog tag nrho cov txheej txheem ntawm cov khoom siv refractory suav nrog tag nrho cov txheej txheem saum toj no. Ntxiv nrog rau kev tsim qauv, kev npaj av nkos, kev ziab thiab kev kho cua sov yog tsim nyog, lwm cov txheej txheem tsis tsim nyog rau txhua yam khoom.
Tam sim no, cov txheej txheem tsim khoom ntawm magnesia dolomite cib hauv Suav teb yog raws li hauv qab no: magnesia calcium xuab zeb lossis dolomite xuab zeb, fused magnesia, sintered magnesia li raw khoom, thiab anhydrous resin lossis paraffin ua tus neeg sawv cev. Tom qab qhov kev ntsuas particle raug txiav txim siab, magnesia calcium xuab zeb yog siv los ua aggregate, fused magnesia yog siv los ua hmoov zoo, kub sib tov yog siv, kub molding yog siv, thiab raug rho tawm haujlwm hauv qhov cub. Cov cib raug rho tawm haujlwm feem ntau yog kho nrog impregnated asphalt thiab impregnated ciab nyob rau hauv lub tshuab nqus tsev, txhawm rau muab cov qauv cib thiab txhim kho nws cov dej tsis kam.
2. Tswj cov yam ntxwv ntawm waterproofing nyob rau hauv cov txheej txheem zus tau tej cov magnesia dolomite cib
Txhua yam ntawm cov txheej txheem tsim cov magnesium-calcium cib yuav tsum tiv thaiv hydration, pib los ntawm kev khaws cia cov ntaub ntawv raw, cov ntaub ntawv raw yuav tsum muaj kev txuag dej kom zoo, xws li kev siv cov thoob ntim, cov hnab yas ntau txheej thiab lwm yam kev ntsuas. Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev khaws cov hmoov zoo, xws li dolomite hmoov zoo, magnesium calcium xuab zeb hmoov zoo thiab txawm tias magnesia hmoov zoo yuav tsum tau ua tib zoo khaws cia cov dej tsis zoo, vim tias cov dej ua haujlwm ntawm cov hmoov zoo dua, nws yooj yim dua rau kev ua haujlwm. nrog dej vapor los ua kom hydration hnyav, tshwj xeeb tshaj yog nyob rau hnub los nag thiab av noo caij nyoog. Vim hais tias ib zaug cov khoom siv raw yog hydrated, qhov kev ua tau zoo ntawm cov npaj magnesia-calcium cib yog qhov loj, qhov kev ua tau zoo ntawm cov cib yooj yim yuav poob mus rau ib nrab ntawm qhov qub lossis tseem phem dua. Hauv kev sib xyaw thiab molding txheej txheem yog tsim rau ib puag ncig qhuav, cov khoom sib xyaw tsis tuaj yeem muab tso rau ntev heev yuav tsum tau tsim nyob rau lub sijhawm luv luv. Rau molding zoo cib qauv kuj yuav tsum tau calcined sai li sai tau, calcined zoo magnesia dolomite cib ntau xav tau kev ntsuas dej tsis zoo, kev siv ntau txoj kev yog impregnated paraffin siv quav ciab txoj kev, kaw ntim txoj kev thiab hais txog.
