Qhov piv ntawm tus nqi thiab concentration ntawm cov ntawv khi rau phosphoric acid refractory castables yog qhov txuas tseem ceeb los xyuas kom meej qhov kev ruaj ntseg ntawm kev ua tau zoo thiab kev tsim kho zoo ntawm cov castables refractory. Yuav ua li cas yog qhov tsim nyog piv ntawm tus nqi thiab concentration ntawm binder rau phosphate bondedsiab alumina refractory castables?
1. Tus qauv piv txwv
Tus nqi thiab qhov sib piv ntawm cov binder rau phosphoric acid refractory castables yuav tsum ua raws li qee cov qauv. Ua ntej, qhov tsim nyog hom thiab qhov sib piv ntawm cov binder yuav tsum raug xaiv raws li hom, siv cov xwm txheej thiab kev ua tau zoo ntawm cov castables refractory. Qhov thib ob, kev sib koom ua ke ntawm cov binder thiab cov khoom sib xyaw refractory yuav tsum tau txiav txim siab los xyuas kom meej tias cov castable muaj lub zog siab thiab ua haujlwm ntev. Thaum kawg, kev tsim kho ib puag ncig thiab cov txheej txheem yuav tsum tau txiav txim siab los kho tus nqi thiab qhov concentration ntawm cov ntaub ntawv kom ua tiav cov txiaj ntsig zoo tshaj plaws.
2. Muaj feem cuam tshuam
Qhov piv ntawm tus nqi thiab concentration ntawm cov ntaub ntawv rau phosphoric acid refractory castables yog cuam tshuam los ntawm ntau yam. Ntawm lawv, hom, particle loj tis thiab nto thaj chaw ntawm refractory aggregate muaj ib qho tseem ceeb cuam tshuam rau lub adsorption thiab binding muaj peev xwm ntawm lub binder. Tsis tas li ntawd, qhov kub, av noo thiab kev sib xyaw ntawm kev tsim kho ib puag ncig kuj yuav muaj qee yam cuam tshuam rau qhov piv. Yog li ntawd, hauv kev ua haujlwm tiag tiag, nws yog ib qho tsim nyog yuav tsum tau hloov kho kom tsim nyog raws li qhov xwm txheej tshwj xeeb kom ntseeg tau tias qhov sib piv tsim nyog thiab kev ua haujlwm ruaj khov.
3. Kev ua haujlwm tshwj xeeb
Hauv kev ua haujlwm tiag tiag, hom thiab tus nqi ntawm cov ntaub ntawv yuav tsum tau txiav txim siab raws li cov khoom siv los yog cov qauv tsim. Tom qab ntawd, qhov yuav tsum tau binder concentration yog xam raws li qhov hnyav los yog ntim ntawm refractory aggregate. Thaum lub sij hawm sib tov, cov binder thiab dej yuav tsum sib tov sib npaug ntawm ib qho kev faib ua feem, thiab tom qab ntawd cov refractory aggregate yuav tsum maj mam ntxiv thiab tag nrho stirred kom txog thaum ib tug uniform castable yog tsim. Thaum kawg, nchuav thiab kho yog ua raws li kev tsim kho.
Qhov piv ntawm tus nqi thiab concentration ntawm binder rau phosphoric acid refractory castables yog qhov txuas tseem ceeb los xyuas kom meej qhov kev ua haujlwm ruaj khov thiab kev tsim kho zoo ntawm refractory castables. Hauv kev ua haujlwm tiag tiag, kev faib ua feem yuav tsum tau ua raws li, qhov cuam tshuam cuam tshuam yuav tsum raug txiav txim siab, thiab txoj kev ua haujlwm raug yuav tsum raug coj los ua kom ua tiav cov txiaj ntsig zoo tshaj plaws.
