Lub luag haujlwm tseem ceeb ntawm kev lag luam chimney yog tshem tawm cov pa taws pov tseg ntawm lub qhov cub, thiab tib lub sijhawm, nws tseem tiv thaiv cov nplaim taws ntawm qhov cub. Thaum qhov kub ntawm cov pa khib nyiab nkag mus rau hauv lub chimney siab, cov phab ntsa sab hauv feem ntau ua nrog cov txheej txheem ua haujlwm. Yog tias cov pa roj flue yog acidic, acid refractory bricks yog tsim, thiab lub teeb yuag refractory castables kuj siv. Lub chimney yog ib qho khoom siv tseem ceeb hauv kev tsim khoom. Nws ua txoj haujlwm tseem ceeb ntawm kev tso cov pa khib nyiab pov tseg. Nws tsis tsuas yog ua kom lub cev ua haujlwm ntawm kev lag luam, tab sis tseem cuam tshuam rau kev nyab xeeb ntawm kev ua haujlwm ntau lawm. Yog li ntawd, kev tsim kho ntawm lub chimney tseem ceeb heev. Ntxiv rau qhov muaj peev xwm Nws tuaj yeem tiv taus qhov kub thiab txias thiab tiv taus cov pa ya yaig hauv qhov chaw ua haujlwm hnyav. Yuav kom ua tau raws li qhov chaw ua haujlwm zoo li no, nws yog ib qho tseem ceeb heev uas yuav tsum tsim cov chimney refractory fire bricks rau chimneys.
Txij li thaum chimney refractory bricks yog ib qho tseem ceeb heev rau kev tsim kho ntawm chimneys, peb yuav tsum xyuam xim rau tej yam thaum yuav khoom. Ua ntej tshaj plaws, thaum yuav khoom, peb yuav tsum xaiv raws li ib puag ncig siv. Peb yuav tsum saib cov cim qhia lub cev thiab tshuaj lom neeg ntawm chimney refractory hluav taws cib, acid resistance A series ntawm lub cev thiab tshuaj ntsuas ntsuas xws li tshuaj tiv thaiv, alkali tsis kam thiab refractory kub. Qhov tseeb, thaum yuav khoom, peb yuav tsum tshuaj xyuas cov chaw tsim khoom lag luam, cov cuab yeej tsim khoom, cov qauv khoom, kev pab cuam tom qab muag thiab lwm yam, kom peb tuaj yeem yuav cov khoom siv hluav taws xob zoo refractory cib.
Qhov muaj pes tsawg leeg ntawm chimney refractory bricks yog tsuas yog ua los ntawm alumina, silica thiab lwm yam ntaub ntawv uas muaj siab melting ntsiab lus. Cov ntaub ntawv no tau ua ke nrog cov ntawv khi, tuag-cam khwb cia nrog cov tshuab ua haujlwm siab, thiab thaum kawg raug rho tawm haujlwm nyob rau hauv qhov chaw kub kub. Nws tuaj yeem ua rau lub chimney muaj hluav taws kub. Nyob rau tib lub sijhawm, lub chimney refractory hluav taws cib yuav raug calcined ntawm qhov kub thiab txias thaum lub sij hawm tsim cov txheej txheem kom nws denser thiab muaj cov thermal rwb thaiv tsev zoo, yog li tiv thaiv cov qauv sab hauv ntawm lub chimney los ntawm qhov kub thiab txias. Thaum tshav kub kub puas.
Hluav taws kub yog ib hom cib uas tuaj yeem tiv taus qhov kub thiab txias. Nws tsis tsuas yog yuav tsum tau tiv thaiv qhov kub ntawm cov pa luam yeeb, tab sis kuj yuav tsum muaj lub cev ruaj khov thiab tshuaj lom neeg ntawm qhov kub thiab txias. Nws tsis yooj yim rau hlawv, corroded, los yog tawg. Cov txiaj ntsig no yog Qhov no ua rau nws zoo tshaj plaws hauv kev tsim kho chimney, tab sis cov cib zoo tib yam nyuaj kom ua tau raws li cov kev ua haujlwm zoo li no. Xws li kub kub tsis tuaj yeem zam los ntawm cov cib tsoos. Thermal expansion thiab contraction yuav ua rau cov cib tawg thiab txawm ua rau lub chimney puas.
Qhov zoo ntawm chimney brickwork thiab kev nyab xeeb kev tsim kho yuav tsum yog tus yuam sij kom ntseeg tau tias kev nyab xeeb thiab kev pab lub neej ntawm lub chimney. Thaum lub sij hawm bricklaying txheej txheem, yuav tsum tau ua raws li nruj me ntsis raws li cov kev cai ntawm bricklaying thiab txhim kho kev ruaj ntseg ntawm lub chimney. Tsis tas li ntawd, cov neeg ua haujlwm tsim kho yuav tsum muaj kev txawj ntse thiab kev paub dhau los, thiab kev kawm txog kev nyab xeeb thiab kev cob qhia yuav tsum tau ntxiv dag zog los txhim kho kev paub txog kev nyab xeeb thiab kev txawj ntawm cov neeg ua haujlwm tsim kho.
Yog li ntawd, thaum siv refractory bricks nyob rau hauv chimneys, tshwj xeeb yuav tsum tau them nyiaj mloog mus rau lub siab kub kuj, corrosion kuj, thiab thermal conductivity ntawm refractory hluav taws cib. Txhawm rau kom muaj kev nyab xeeb thiab kav ntev ntawm lub chimney.
