Raw Materials Rau Refractory Materials
Refractoriesxa mus rau cov ntaub ntawv uas muaj siab hnav tsis kam, slag kuj, erosion kuj, kub stability thiab tshuaj yaig kuj nyob rau hauv hnyav ib puag ncig xws li kub thiab muaj zog acid thiab alkali. Refractories yog ua los ntawm silicon, txhuas, magnesium, calcium, zirconium thiab lwm yam ntaub ntawv tseem ceeb los ntawm batching, molding, sintering thiab lwm yam txheej txheem. Cov ntaub ntawv raw ntawm refractories yuav qhia kom ntxaws hauv qab no.A, silicate raw khoomSilicate raw khoom yog lub ntsiab ntawm silica hauv refractories. Lawv suav nrog quartz xuab zeb, wollastonite, siliceous pob zeb, thiab lwm yam. Quartz xuab zeb yog feem ntau siv ntawm lawv. Silicate raw cov ntaub ntawv muaj cov yam ntxwv ntawm qhov kub thiab txias stability, kev ua haujlwm zoo heev thiab kev ua haujlwm zoo sintering.
Qhov thib ob, alumina raw cov ntaub ntawvAlumina raw khoom yog cov feem ntau siv alumina qhov chaw nyob rau hauv refractories. Lawv suav nrog aluminium oxide hmoov, dawb corundum, mullite, iav ballast, thiab lwm yam. Ntawm lawv, aluminium oxide hmoov yog feem ntau siv, tab sis vim nws cov nqi siab, lwm cov khoom siv alumina pheej yig yog siv ntau dua.
Thib peb, magnesium raw khoomMagnesium raw cov ntaub ntawv feem ntau suav nrog lub teeb hlawv magnesium, magnesite, lens pob zeb, ntshiab xuab zeb magnesite thiab lwm yam. Lub teeb hluav taws xob magnesia yog ib qho ntawm cov khoom siv magnesia feem ntau siv. Magnesium raw cov ntaub ntawv muaj cov yam ntxwv ntawm zoo kub stability, siab mechanical zog, zoo heev yaig kuj thiab thiaj li nyob.
Plaub,silicon pob zeb diamond raw cov ntaub ntawv
Silicon pob zeb diamond khoom yog ib yam tshiab ntawm cov khoom siv refractory. Lawv suav nrog microcrystalline silicon pob zeb diamond, crystalline silicon pob zeb diamond thiab polycrystalline silicon pob zeb diamond. Silicon pob zeb diamond raw cov ntaub ntawv muaj qhov zoo ntawm hluav taws kub tsis kam, corrosion kuj thiab siab mechanical zog.
Tsib, lwm yam khoom siv raw
Ntxiv rau cov ntaub ntawv tseem ceeb saum toj no, cov khoom siv raw ntawm cov refractories kuj suav nrog kev ua quartz, calc pob zeb, lead pyroxene, pob tshab ceramics, silicon nitride thiab lwm yam. Cov khoom siv raw no muaj cov yam ntxwv sib txawv thiab cov peev txheej ntawm daim ntawv thov, dav siv hauv kev tsim khoom ntawm txhua yam khoom siv refractory.Nyob rau hauv cov ntsiab lus, cov ntaub ntawv raw ntawm cov ntaub ntawv refractory feem ntau muab faib ua silicate, alumina, magnesium, silicon pob zeb diamond thiab lwm yam ntaub ntawv raw. Kev xaiv thiab siv cov khoom siv raw no yuav tsum ua kom haum raws li qhov xwm txheej tshwj xeeb kom tau raws li qhov xav tau ntawm ntau lub sijhawm. Nrog rau kev siv dav hauv qhov chaw hnyav xws li qhov kub thiab txias thiab muaj zog acid thiab alkali, qhov kev thov rau cov khoom siv refractory kuj nce ntxiv, thiab kev ruaj ntseg, zoo thiab tus nqi ntawm cov khoom siv raw kuj tau txais ntau thiab ntau xim los ntawm cov tuam txhab.
