Nyob rau hauv niaj hnub kev lag luam toj roob hauv pes, kev siv hluav taws xob tau dhau los ua ib qho tseem ceeb tshaj plaws rau cov tuam txhab lag luam hauv steel, ceramics, iav, thiab petrochemical industries. Nrog rau kev nce nqi roj thiab nruj dua cov qauv ntawm cov pa roj carbon monoxide, qhov kev xav tau ntawm cov khoom siv thermal rwb thaiv tsev siab tshaj qhov qub. Ntawm tag nrho cov kev daws teeb meem refractory,mullite rwb thaiv tsev cibstands raws li ib tug txhim khu kev qha, lub teeb yuag, thiab lub zog - txuag cov ntaub ntawv tsim tshwj xeeb rau siab - kub daim ntawv thov.
Mullite Insulation Cib yog dab tsi?
Rwb thaiv tsev Mullite cib yog lub teeb yuag refractory cib tsim feem ntau ntawm alumina (Al₂O₃) thiab silica (SiO₂), nrog mullite (3Al₂O₃·2SiO₂) ua lub ntsiab crystalline theem. Cov cib yog tsim los ntawm kev kub siab - kub hnyiab los yog los ntawm sintering siab - purity raw khoom xws li bauxite, kaolin, los yog alumina hmoov.
Tsis zoo li cov firebricks ntom ntom, mullite insulating cib muaj qhov ntom ntom ntom (0.6-1.2 g / cm³) thiab siab porosity, uas txo cov cua sov thiab thermal conductivity thaum tswj cov khoom zoo ntawm qhov kub siab.
Cov khoom tseem ceeb ntawm Mullite Rwb thaiv tsev cib
Zoo heev Thermal rwb thaiv tsev
Qhov qis thermal conductivity ntawm mullite insulating cib txo qis thaum tshav kub kub poob, kom ruaj khov rauv kub thaum txo lub zog noj.
High Refractoriness thiab Structural Strength
Cov cib no tuaj yeem tiv taus qhov kub thiab txias mus txog 1650 degree, ua rau lawv zoo tagnrho rau siv nyob rau hauv siab -kub rauv, kilns, thiab reactors.
Tsawg Kub Cia
Ua tsaug rau lawv cov qauv sib sib zog nqus, mullite cib ua kom sov thiab txias sai sai, ua kom muaj kev ua haujlwm zoo thaum lub qhov cub pib-ups thiab shutdowns.
Zoo Thermal Shock Resistance
Mullite qhov tshwj xeeb microstructure tso cai rau lub cib los tiv thaiv kev tawg thiab tawg los ntawm kev hloov kub ceev.
Tshuaj Stability
Mullite rwb thaiv tsev firebricks tiv thaiv corrosion los ntawm feem ntau cov kua qaub thiab alkalis, kom ntseeg tau ntev -lub sij hawm durability txawm nyob rau hauv ib puag ncig txhoj puab heev.
Daim ntawv thov ntawm Mullite Rwb thaiv tsev Cib hauv Industrial Furnaces
Ceramic Kilns:Siv raws li hauv ob sab phlu thiab thaub qab rwb thaiv tsev kom ruaj khov firing kub.
Iav Furnaces:Siv nyob rau hauv cov yas yas thiab regenerator rwb thaiv tsev zones kom txo tau kub.
Kev lag luam hlau:Zoo tagnrho rau reheating rauv, ladle npog, thiab cua sov-chamber kho mob.
Cement thiab Lime Kilns:Muab kev rwb thaiv tsev zoo nyob rau hauv preheating thiab calcination zones.
Petrochemical Rauv:Siv nyob rau hauv kev hloov kho thiab tawg rauv vim nws thermal stability.
Vim li cas Mullite Rwb thaiv tsev Cib Txhim Kho Zog Efficiency
Lub zog efficiency nyob rau hauv industrial furnaces feem ntau nyob ntawm seb yuav ua li cas cov cua sov yog khaws cia nyob rau hauv lub system. Cov tsoos firebricks muaj kev ruaj khov tab sis kuj nqus cov cua kub ntau, uas ua rau lub zog pov tseg thaum lub sij hawm cua sov.
Los ntawm qhov sib txawv, lub teeb yuag mullite rwb thaiv tsev firebricks ua raws li thermal barrier - reflecting cua sov rov qab rau hauv lub cub tawg chamber. Qhov no txo qis zog poob thiab tuaj yeem txuag tau li 10-30% ntawm tag nrho cov roj siv, nyob ntawm qhov tsim ntawm lub cub tawg.
Tsis tas li ntawd, lawv lub teeb yuag txo qhov hnyav ntawm cov txheej txheem ntawm cov phab ntsa ntawm lub cub tawg thiab kev txhawb nqa, txo qis kev tsim kho thiab kho cov nqi.
Kev sib piv: Mullite rwb thaiv tsev cib vs. Fireclay cib
| Khoom | Mullite rwb thaiv tsev cib | Fireclay Cib |
|---|---|---|
| Ua haujlwm kub | Mus txog 1650 degree | Mus txog 1400 degree |
| Qhov ntom ntom (g / cm³) | 0.8–1.2 | 1.8–2.2 |
| Thermal conductivity (W / m · K) | 0.20–0.35 | 1.0–1.3 |
| Zog Efficiency | Siab | Nruab nrab |
| Daim ntawv thov Focus | Rwb thaiv tsev txheej | Txheej Txheej |
