Andalusite cib

Andalusenite cib yog ib cov khoom siv refractory nrog thiab cov khoom siv cov khoom nyoos. Cov ntaub ntawv raw tseem corundum thiab Andalusite, thiab lwm yam. Nws tau npaj los ntawm cov txheej txheem tshiab ntws nrog ntau-theem batching, matrix homogenization, thiab kev txiav txim siab ntawm kev ua kom sov siab. Nws muaj cov kub siab ua tsis tau zoo, hnav tsis kam thiab corrosion tsis kam, raws li tau zoo heev rau cov cua sov ua hauj lwm zoo. Lub cib no tuaj yeem nyob ruaj khov nyob rau ib puag ncig kub thiab tsis yooj yim rau deform lossis tawg. Thaum lub sijhawm cov txheej txheem ntau lawm, nws yog tsim los ntawm kev ntxiv additives xws li mullite thiab yog tsim los ntawm kev kub siab moulding, kom qhuav thiab tua hluav taws ntawm 1500 degree. Nws qhov refactoriness tuaj yeem ncav cuag ntau dua 1800 degree, thiab nws tuaj yeem hloov dua siab tshiab mus rau mullite ntawm qhov kub thiab txias, ntxiv kev txhim kho nws cov refactoriness. Tsis tas li ntawd, nws tseem muaj cov kev siv tshuab lub zog Cov ntaub ntawv no yog feem ntau yog siv hauv kev lag luam kom tiv thaiv kom muaj qhov kub thiab txias, tshwj xeeb tshaj yog cov ua kom sov sov xws li cov cua sov kub heev xws li cov hluav taws kub tawg.

Hauj lwm lawm

Andalususite cib yog ua los ntawm Andalusite, Sillimanite xuab zeb, ua kom Alumina hmoov thiab nplua-alumina hmoov. Ua ntej, 4 {0% ntawm Andalusite nrog ib qho loj me ntawm {4 5}} mm thiab 20 {mm} mm yog noj. Lub {120- mesh activated alumina liab thiab cov cib regractory yuav hloov mus rau mullite tom qab cua sov. Tom qab hloov dua siab tshiab, lawv muaj kev ua haujlwm ntau dua. Kev ua refactoriness tuaj yeem ncav cuag saum toj 1800 degree. Muaj tsawg heev impurities nyob rau hauv Andalusite cib, thiab lub zog siab txo qis tsawg me ntsis. Nws tseem muaj cov yam ntxwv ntawm kev tiv taus sai thiab cua sov, muaj zog dua rau hauv hydrofluoric acid) thiab muaj zog heev rau tshuaj corrosion.

Andalusite muaj cov kub ua hauj thiab ruaj khov. Thaum rhuab rau 1350 degree nyob rau hauv ib txwm siab, Andalusite pib hloov mus rau rab koob mullite. Mullite siv lead ua yog tsuas yog qhov ruaj khov ntawm alleosilicate nyob rau hauv kub siab.

Andalusenite cib Siv Cornundum, Andalusite thiab lwm yam ntaub ntawv raws li cov ntaub ntawv sib tw thiab nruj me ntsis tswj cov khoom nyoos. Cov thev naus laus zis tshiab yog siv, thiab ntau qib kev sib tw, matrix homogenization, kev txiav txim siab ntawm kev saib ntsuas kub zoo thiab lwm yam kev ntsuas kev ntsuas tau los. Andalususite cib ua tau zoo tau tuaj yeem sib ntsib kev siv ntau qhov chaw thiab cov hluav taws ua haujlwm sib txawv ntawm cov hluav taws kub.

Tus yam ntxwv ntawm Andalusite C cib yog tias tus ntsuas kev nthuav dav hluav taws xob feem ntau yog qis thaum lub sijhawm hloov dua siab tshiab. Andalusite cib tau muab faib ua ob hom, ib qho yog cov thwv cib tau rho tawm, thiab lwm tus ua thwv cib tsis muaj txiaj ntsig.
