Dab tsi yog cov ntsiab lus ntawm txhuas ntawm mullite cib, thiab dab tsi yog qhov txawv ntawm sintering thiab electrofusion?
Mullite bricksfeem ntau muaj li ntawm 55% mus rau 80% txhuas oxide (Al2O3), tab sis cov ntsiab lus txhuas tshwj xeeb yuav txawv nyob ntawm txoj kev tsim khoom, raw khoom zoo thiab cov txheej txheem tsis.
Qhov txawv ntawm sintering thiab electrofusion:
Sintering: Qhov no yog ib txoj hauv kev los npaj cov khoom siv, xws li ceramics, hlau, alloys, thiab lwm yam. Thaum lub sij hawm sintering txheej txheem, hmoov los yog granular raw cov ntaub ntawv yog rhuab mus rau ib tug kub txaus, tab sis tsis tag melted, los tsim ib tug kev sib raug zoo ntawm cov khoom. cov khoom. Kev sib xyaw ua ke ntawm cov khoom no yog hu ua lub caj dab. Lawv tsim ib qho kev sib txuas pore network ntawm lub caj dab, muab cov khoom muaj zog thiab cov duab. Cov txheej txheem ntau lawm ntawm sintered mullite cib zoo ib yam li ntawmsiab alumina refractory cib.
Hluav taws xob Fusion: Qhov no yog ib txoj hauv kev siv hluav taws xob hluav taws xob los ua kom sov cov ntaub ntawv mus rau qhov kub thiab txias. Nyob rau hauv cov txheej txheem electrofusion, ib tug loj npaum li cas ntawm tshav kub lub zog yog generated los ntawm kev dhau ib tug hluav taws xob tam sim no los ntawm ib tug kuj nyob rau hauv cov khoom, ua rau cov khoom yaj. Txoj kev no feem ntau siv los npaj cov khoom siv purity siab, ua haujlwm siab vim tias nws tso cai rau kev tswj xyuas ntau dua ntawm cov khoom siv tshuaj lom neeg thiab cov qauv. Fused mullite cib yog tsim los ntawm high-alumina bauxite los yog muaj alumina, av nplaum los yog silica, yaj nyob rau hauv ib tug hluav taws xob arc rauv, ces cam khwb cia thiab annealed los ua refractory cib. Lub ntsiab mineral tivthaiv yog mullite.
Sintered mullite cib yog cov txheej txheem uas cov hmoov nyoos los yog cov ntaub ntawv granular tau rhuab los ua ib daim ntawv cog lus ntawm cov khoom, thaum fused mullite refractory bricks yog txheej txheem uas hluav taws xob siv hluav taws xob siv los ua kom sov cov khoom mus rau qhov kub thiab txias. Kev xaiv ntawm ob yog nyob ntawm cov khoom siv. Nyob ntawm cov xwm txheej xws li qhov xwm txheej, cov qauv tsim nyog thiab kev ua tau zoo, kev ua haujlwm ntawm cov cib mullite no txawv. Thov xaiv cov khoom tsim nyog raws li koj xav tau.
