Nyob rau lub Yim Hli 58 tons Jm26 Insulating Fire Bricks tau ntim khoom xa tuaj rau peb cov neeg siv khoom hauv Romania. Zaj lus no Topower Refractory yuav tham txog Alumina cov ntsiab lus ntawm lub teeb yuag mullite cib (Jm26 Insulating Fire Brick).
Cov khoom siv raw ntawm lub teeb mullite cib (Jm26 Insulating Fire Brick) feem ntau yog siv cov khoom siv refractory nrog kyanite ua cov khoom siv tseem ceeb, vim tias ntau cov micropores yog tsim los ntawm cov particle skeletons ntawm kyanite nyob rau hauv tus txheej txheem ntawm decomposition thiab expansion. Lub xub ntiag ntawm cov pores no txo cov erosion tsis kam ntawm cov khoom refractory uas yog nyob rau hauv kev sib cuag nrog cov yaj. Lub teeb yuag mullite cib (Jm26 Insulating Fire Cib) yog siv rau hauv ob sab phlu ntawm cov kub kub uas tsis sib cuag nrog cov yaj. Lawv tsis tsuas yog xav tau kev pabcuam siab kub, tab sis kuj xav tau thermal conductivity tsawg. Rau lub teeb yuag refractories (Jm26 Insulating Hluav Taws Cib), nyob rau hauv ib tug tej yam ntau yam, qhov me me qhov pore loj, qhov qis thermal conductivity. Yog li ntawd, cov micropores tsim los ntawm decomposition thiab nthuav dav ntawm kyanite yog qhov zoo rau kev txhim kho thermal rwb thaiv tsev kev ua tau zoo ntawm lub teeb mullite cib (Jm26 Insulating Fire Brick).
Qhov zoo tshaj plaws tshuaj muaj pes tsawg leeg ntawm mullite yog 3AL2O3 2SiO2, uas AL2O3 suav rau 71.8 feem pua thiab SiO2 suav rau 28.2 feem pua. Nws cov ntsiab lus melting yog 1910 degree, uas yog cov ntxhia theem thib ob rau corundum (melting point 2050 degree) hauv aluminium silicate system. Yog li ntawd, lub teeb mullite cib (Jm26 Insulating Fire Brick) nrog mullite raws li lub ntsiab siv lead ua theem muaj qhov kub thiab txias. Yog tias kyanite tau hloov mus rau mullite tag nrho thaum lub sij hawm decomposition, alumina yuav tsum tau ntxiv rau cov hmoov av kyanite.
Txhawm rau ua kom lub teeb mullite cib (Jm26 Insulating Fire Cib) muaj cov ntsiab lus siab txaus mullite thiab tib lub sijhawm ua rau cov khoom ncav cuag qhov txaus ntawm sintering nyob rau hauv qhov kub thiab txias, AL2O3 cov ntsiab lus ntawm lub teeb mullite cib ( Jm26 Insulating Fire Cib) raug xaiv los ua 67.1, me ntsis qis thiab zoo tagnrho muaj pes tsawg leeg nrog mullite.
Lub teeb yuag mullite refractory cib (Jm26 Insulating Fire Cib) muaj cov yam ntxwv ntawm kev pabcuam siab kub, tsis muaj peev xwm kub, tsis tshua muaj thermal conductivity, siab zog, thiab zoo thermal shock resistance. Lub teeb mullite cib (Jm26 Insulating Fire Brick) nrog AL2O3 cov ntsiab lus ntawm 67.1 feem pua tsim los ntawm kyanite thiab industrial alumina hmoov yog tsuas yog siv nyob rau hauv ntau yam kilns ntawm niaj hnub ceramics, architectural ceramics thiab tshwj xeeb industrial ceramics, thiab ntau yam kub kub nyob rau hauv lub petrochemical kev lag luam. Furnaces, ntau yam high-qib cua sov rauv thiab loj-scale kub blast furnaces nyob rau hauv lub metallurgical kev lag luam yog siv rau ncaj refractory hauv ob sab phlu. Nyob rau hauv cov kilns, thaum ua hauj lwm kub siab tshaj qhov kub uas lwm yam khoom siv yuag (Jm26 Insulating Fire Cib) tuaj yeem tiv taus (xws li refractory fibers), thiab muaj cov khoom siv uas yuav tsum tau siv, ntau yam khoom ntawm lub teeb yuag refractory cib ( Jm26 Insulating Fire Cib) tuaj yeem siv tau tag nrho.
