Tab sis koj yuav txiav txim siab li cas qib ntawm mullite cib zoo tshaj plaws rau koj daim ntawv thov? Kab lus no piav qhia txog qhov sib txawv ntawm cov qib no thiab muab cov lus qhia ua tau zoo rau cov neeg yuav khoom thiab cov kws tsim khoom siv refractory.
Dab tsi yog Mullite Insulation Bricks?
Mullite rwb thaiv tsev refractory cib yog cov khoom sib sib zog nqus refractory ua los ntawm siab -purity alumina thiab silica. Qhov tseem ceeb crystalline theem yog mullite (3Al₂O₃·2SiO₂), uas muab cov cib zoo thermal stability thiab txhua yam muaj zog ntawm qhov kub siab.
Lawv tau tsim los nrog kev tswj cov porosity thiab tsis tshua muaj qhov ntom ntom kom ua tiav cov thermal conductivity tsawg thaum tswj kev ua haujlwm zoo. Feem ntau qhov ntom ntom yog li ntawm 0.6 txog 1.2 g / cm³, ua rau lawv sib zog dua li cov pob zeb tawg.

| JM 23 | 1260 | 46–48 | 0.6–0.9 | 0.16–0.20 | Kiln rwb thaiv tsev, thaub qab hauv ob sab phlu, cua sov-kho qhov cub |
| JM 26 | 1400 | 55–57 | 0.8–1.0 | 0.18–0.22 | Ceramic kilns, iav furnaces, petrochemical heaters |
| JM 28 | 1500 | 65–68 | 1.0–1.2 | 0.20–0.25 | High -kub muaj rauv taws, teb kilns, steel reheating rauv |
Qhov txawv ntawm JM23, JM26, thiab JM28
Kub Resistance
JM23 cib yog qhov zoo tagnrho rau kev rwb thaiv tsev qis rau nruab nrab.
JM26 ua haujlwm kub siab txog li 1400 degree.
JM28 yog qhov zoo tshaj plaws rau kev thov siab - qhov chaw kub txog li 1500℃.
Zog Efficiency
JM23 muaj cov thermal conductivity qis tshaj plaws, ua rau nws xaiv qhov zoo tshaj plaws qhov kev ua haujlwm rwb thaiv tsev yog qhov tseem ceeb.
JM28, ua denser, muaj cua sov me ntsis cia tab sis muab lub zog zoo dua thiab ua haujlwm ntev.
Mechanical Strength thiab Durability
JM28 cib muaj lub zog crushing siab tshaj plaws thiab zoo dua rau kev thauj khoom -cov cheeb tsam ntawm lub cub tawg.
JM23 thiab JM26 feem ntau yog siv tsis yog -load- cov kab hluav taws xob rwb thaiv tsev.
Kev txiav txim siab nqi
JM23 yog qib qis tshaj plaws.
JM28, nrog ntau dua alumina cov ntsiab lus thiab lub zog, tuaj ntawm tus nqi tab sis muaj kev pab cuam ntev dua.

Yuav Ua Li Cas Xaiv Txoj Cai Mullite Cib rau Koj Lub Rauv
Thaum xaiv cov qib uas tsim nyog, xav txog cov ntsiab lus tseem ceeb no:
Ua haujlwm kub:
Ib txwm xaiv ib lub cib nrog qhov siab tshaj plaws ua haujlwm kub ntawm 10-15% siab tshaj qhov cub ua haujlwm li niaj zaus.
Rwb thaiv tsev Efficiency:
Rau lub zog-txuag rauv, ua qhov tseem ceeb ntawm cov thermal conductivity qis dua li JM23 lossis JM26 rau txheej thaub qab.
Mechanical Load thiab Position:
Cov cheeb tsam uas muaj kev ntxhov siab ntau dua (xws li cov plag tsev hauv tsev lossis chaw thau khoom-cov phab ntsa) yuav tsum siv JM28.
Atmosphere thiab roj hom:
Furnaces nrog fluctuating oxidizing / txo cov cua tau txais txiaj ntsig los ntawm kev ruaj ntseg ntawm JM26 lossis JM28.
Nqi vs. Ntev:
Thaum JM28 raug nqi ntau dua, nws muab lub neej ntev dua thiab txo - cov nqi tu lub sijhawm.
Peb cov mullite rwb thaiv tsev cib tau ntseeg los ntawm cov neeg siv khoom thoob plaws hlau, iav, ceramic, thiab petrochemical kev lag luam thoob ntiaj teb.
Xaiv txoj cai mullite cib qib yog nyob ntawm qhov ntsuas kub qhov xav tau, lub zog, thiab kev ua haujlwm rwb thaiv tsev.
JM23: Qhov zoo tshaj plaws rau qis- rwb thaiv tsev kub thiab lub zog- txuag daim ntawv thov.
