Mullite rwb thaiv tsev bricksyog cov ntaub ntawv refractory feem ntau yog tsim los ntawm mullite (3Al₂O₃·2SiO₂), cov ntxhia paub txog nws cov thermal stability thiab tsis tshua muaj thermal conductivity. Cov cib no yog tsim los muab cov rwb thaiv tsev zoo nyob rau hauv siab - qhov kub thiab txias ib puag ncig, ua kom muaj zog ua haujlwm thiab kev nyab xeeb.
Cov txheej txheem tsim khoom suav nrog kev tswj hwm cov ntaub ntawv raw, suav nrog siab -purity hluavtaws mullite, hwm kaolin, thiab ua tib zoo xaiv cov khoom siv alumina. Qhov kev ua kom zoo zoo no ua kom muaj kev sib raug zoo thiab kev ua tau zoo thoob plaws cov khoom sib txawv -tseem ceeb rau cov ntawv thov kev lag luam uas tsis muaj kev ntseeg siab - sib tham tau.
Superior Thermal Shock Resistance
Tsis zoo li cov pa hluav taws xob cib, mullite rwb thaiv tsev cib ua tau zoo hauv cov ntawv thov uas muaj kev kub ceev ceev. Lawv cov thermal expansion coefficient tsis tshua muaj kev tiv thaiv kev tawg thiab tawg thaum lub sij hawm cua sov thiab cua txias, ncua kev pab cuam lub neej. Cov yam ntxwv no ua rau lawv zoo tagnrho rau batch- hom furnaces thiab kev ua haujlwm tsis sib xws hauv cov khoom siv ceramic, iav, thiab metallurgical industries.
Zoo zog Efficiency
Cov thermal conductivity tsawg ntawm mullite lub teeb ci ci- feem ntau 0.3-0.5 W/m·K ntawm 1000℃- txhais ncaj qha rau hauv kev txuag hluav taws xob. Los ntawm kev txo qis cua sov los ntawm cov phab ntsa hauv lub cub tawg, cov cib no pab cov neeg ua haujlwm hauv kev lag luam txo cov roj noj los ntawm 15-25% piv rau cov khoom siv hluav taws xob. Nyob rau hauv ib lub sij hawm ntawm kev nce nqi zog thiab ib puag ncig cov cai, qhov no efficiency kom zoo dua muab ntau yam nqi mus sij hawm ntev.
Cov khoom muaj zog kub zoo heev
Txawm hais tias lawv lub teeb yuag, mullite rwb thaiv tsev cib tuav cov khoom siv dag zog zoo ntawm qhov kub siab. Kub crushing lub zog qhov tseem ceeb tshaj 3.5 MPa ntawm 1400℃kom muaj kev ncaj ncees nyob rau hauv load, tiv thaiv deformation los yog vau ntawm lub cub tawg linings thaum lub sij hawm ua hauj lwm.
Chemical Stability hla ntau qhov chaw ib puag ncig
Lub siab -purity muaj pes tsawg leeg ntawm rwb thaiv tsev mullite refractory cib muab kev tiv thaiv zoo rau ob qho tib si acidic thiab yooj yim slags. Lawv cov ntsiab lus tsis tshua muaj hlau oxide (<0.5%) prevents reduction reactions in reducing atmospheres, making them suitable for various industrial processes including steel heat treatment, ceramic firing, and glass melting.
Kev hloov pauv thoob ntiaj teb mus rau lub zog- cov txheej txheem kev lag luam tau zoo thiab cov kev cai ib puag ncig nruj dua tseem ua rau muaj kev xav tau siab - cov ntaub ntawv rwb thaiv tsev ua haujlwm. Mullite rwb thaiv tsev cib sawv cev rau cov pov thawj kev daws teeb meem uas muab cov txiaj ntsig rov qab los ntawm kev siv hluav taws xob tsawg, kev pab lub neej ntev, thiab txhim kho cov txheej txheem kev ntseeg siab.
Rau cov neeg yuav khoom thoob ntiaj teb nrhiav cov neeg muag khoom txhim khu kev qha, koom tes nrog cov tuam txhab tsim muaj kev txhawb nqa dav dav, cov ntawv pov thawj zoo, thiab cov ntaub ntawv pov thawj kev xa tawm ua kom cov txiaj ntsig tau zoo. Kev sib xyaw ua ke ntawm cov khoom siv zoo tshaj plaws thiab cov nqi sib tw ua rau mullite rwb thaiv tsev firebricks qhov kev xaiv ntse rau pem hauv ntej-xav txog kev lag luam thoob ntiaj teb.
Txawm hais tias kho dua tshiab cov cuab yeej uas twb muaj lawm lossis tsim tshiab siab -kub tshuab, xaiv mullite rwb thaiv tsev cib muab cov thermal kev ua tau zoo, txhua yam kev ntseeg siab, thiab cov txiaj ntsig kev lag luam uas niaj hnub siv kev lag luam xav tau.
