Yog tias koj tab tom nrhiav cov ntaub ntawv rwb thaiv tsev kub uas sib npaug rau kev ruaj khov, kev siv hluav taws xob zoo, thiab kev siv tau ntau yam, cov cib mullite sib dua yog koj qhov kev xaiv zoo tshaj plaws. Tsis zoo li cov cib refractory hnyav ib txwm muaj, cov ntaub ntawv siab heev no zoo heev hauv ntau yam kev lag luam - ua tsaug rau lawv qhov kev sib sau ua ke tsawg, kev ruaj khov thermal zoo heev, thiab kev tiv taus thermal shock zoo. Hauv qab no, peb rhuav tshem cov kev siv tseem ceeb ntawm cov cib mullite sib dua thoob plaws cov lag luam tseem ceeb, pab koj nkag siab tias lawv daws koj cov teeb meem rwb thaiv tsev uas nyuaj tshaj plaws li cas.
1. Siv Lub Hauv Paus: Siv Rau Qhov Cub Kub Siab (Hetallurgy & Kev Kho Kub)
Cov chaw tsim hlau thiab cov chaw kho cua sov vam khom cov cub tawg ua haujlwm ntawm 1200–1600 ° C (2192–2912 ° F) - thiab cov cib mullite sib dua yog qhov siv tau rau kev txhim kho cov kab ke tseem ceeb no.
Cov Xwm Txheej Thov:Kev siv cov ntaub thaiv ntawm cov cub tawg annealing, cov cub tawg hardening, thiab cov cub tawg sintering rau cov hlau, txhuas, thiab cov hlau uas tsis yog hlau ua.
Vim Li Cas Nws Ua Haujlwm:Lawv qhov kev ua kom sov qis (≤0.6 W/(m·K) ntawm 1000°C) txo qhov poob cua sov txog li 30% piv rau cov cib refractory txheem, txiav cov nqi roj ntau heev. Tsis tas li ntawd, lawv qhov kev tiv thaiv siab (tsis muaj kev hloov pauv hauv qhov kub siab ntev) ua kom lub cub tawg muaj sia nyob 5-8 xyoo, txo qis lub sijhawm txij nkawm.
2. Tseem ceeb rau Cov Qhov Cub Uas Ua Los Ntawm Pob Zeb Thiab Iav
Kev hlawv cov khoom siv ua los ntawm cov av nplaum thiab cov iav yaj yuav tsum tau tswj qhov kub kom raug (1300–1550°C) thiab tiv taus cov pa roj uas ua rau lub qhov cub puas. Cov cib mullite uas tsis hnyav tau tsim los ua kom tau raws li cov kev xav tau no:
Cov Qhov Cub Uas Ua Los Ntawm Cov Khoom Siv Ua Los Ntawm Cov Khoom Siv Uas Muaj ...Siv ua daim ntaub sab hauv rau cov qhov cub tunnel thiab cov qhov cub shuttle. Lawv qhov thermal mass qis ua rau lub voj voog cua sov/txias sai dua (txo lub sijhawm tua hluav taws los ntawm 15–20%), ua kom cov vuas, cov khoom siv huv, thiab cov khoom siv ceramics hauv kev lag luam zoo dua.
Cov Qhov Cub Iav:Muaj txheej rau hauv lub hau thiab sab ntawm cov cub tawg iav. Lawv cov alumina siab (65–75% Al₂O₃) tiv taus kev yaig los ntawm cov iav yaj thiab cov pa alkaline, tiv thaiv kev ua qias tuaj ntawm cov khoom iav. Qhov no ua kom cov iav zoo ib yam thiab ua kom lub cub tawg siv tau ntev li 2–3 xyoos.
3. Kev rwb thaiv cua sov hauv Petrochemical & Chemical Reactors
Cov chaw tsim roj av (piv txwv li, cov khoom tawg ethylene) thiab cov chaw tsim tshuaj lom neeg ua haujlwm hauv qab qhov xwm txheej hnyav: kub siab (1000–1400 ° C) thiab ib puag ncig tshuaj lom neeg hnyav. Cov cib mullite sib dua muab kev rwb thaiv tsev txhim khu kev qha ntawm no:
Kev rwb thaiv tsev ntawm lub reactor:Siv ua cov khoom rwb thaiv tsev rau cov reactor reactor thiab cov catalytic crackers. Lawv qhov porosity kaw (≤20% dej nqus) tiv thaiv kev nkag mus ntawm cov kua / roj corrosive, tiv thaiv lub reactor lub plhaub hlau los ntawm xeb.
Kev rwb thaiv tsev ntawm cov yeeb nkab thiab cov kav dej:Qhwv ib ncig ntawm cov kav dej kub siab (piv txwv li, cov uas nqa roj kub lossis syngas) kom tswj tau qhov kub ntawm cov kua dej thiab tiv thaiv kev poob cua sov. Qhov no tsis yog tsuas yog txhim kho kev ua haujlwm zoo xwb tab sis kuj txhim kho kev nyab xeeb hauv chaw ua haujlwm los ntawm kev txo qhov kub ntawm cov kav dej.
4. Ib feem tseem ceeb hauv lub zog rov ua dua tshiab (Lub hnub ci thermal & biomass)
Thaum lub ntiaj teb hloov mus rau lub zog rov ua dua tshiab, cov cib mullite sib dua ua lub luag haujlwm tseem ceeb hauv cov txheej txheem hluav taws xob kub siab:
Cov Chaw Fais Fab Thermal Hnub Ci:Muaj cov thoob ntim ntsev uas yaj thiab cov khoom txais, uas khaws cua sov ntawm 565°C rau kev tsim hluav taws xob. Lawv qhov kev ruaj khov thermal ua kom tsis muaj kev puas tsuaj thaum lub sijhawm cua sov/txias, thaum qhov ceev qis txo cov khoom hnyav ntawm cov thoob ntim.
Cov Boilers Biomass:Siv ua cov khoom rwb thaiv tsev rau cov chav hlawv thiab cov kav dej roj flue. Lawv tiv taus cov tshauv thiab xeb los ntawm cov roj biomass (piv txwv li, cov ntoo chips, straw), ua kom lub boiler ua haujlwm tau zoo thiab txo cov nqi kho.
5. Kev Siv Tshwj Xeeb: Cov Khoom Siv Kub Siab Rau Chav Kuaj Mob Thiab Aerospace
Tshaj li qhov ntsuas kev lag luam, cov cib mullite sib dua tau ntseeg siab rau cov ntawv thov raug:
Cov Cub Hluav Taws Xob Hauv Chav Kuaj Mob:Muaj cov khoom siv muffle furnaces thiab tube furnaces rau kev sim khoom siv (piv txwv li, kev tshawb fawb txog ceramic, kev tshuaj xyuas cov hlau alloy). Lawv qhov kev faib tawm thermal sib npaug (qhov kub sib txawv ≤ ± 5 ° C) ua kom ntseeg tau tias cov txiaj ntsig xeem raug.
Kev Ntsuas Huab Cua:Siv rau hauv cov chaw kuaj hauv av rau cov khoom siv ntawm lub cav dav hlau. Lawv tiv taus qhov kub thiab txias heev rau lub sijhawm luv luv (txog li 1800 ° C) thaum lub sijhawm kuaj lub cav hlawv, muab kev rwb thaiv tsev zoo rau cov chav kuaj.
