Nws yog feem ntau siv acid-resistant lightweight castables rau hauv ob sab phlu chimneys. Tab sis yog tias cov castables tseem tsis muaj zog ob peb hnub tom qab tau nchuav, los yog muag muag thaum nias ntawm tes tom qab condensation, yog vim li cas?
1. Ua ntej, ua ib qho kev sim me me ntawm cov khoom seem ntawm lub teeb acid-resistantrefractory castable. Koj tuaj yeem siv lub raj mis dej ntxhia. Ntxiv cov khoom siv rau hauv cov ntawv khi thiab siab alumina cement hauv kev faib ua feem, thiab hliv rau hauv lub raj mis. Nws muaj ib tug kov los tuav cov khoom nyob rau hauv lub raj mis. Muab cov khoom tso rau hauv av ob peb zaug thiab muab tso rau hauv qhov chaw uas nws tsis tuaj yeem raug los nag. Saib seb nws condenses li cas tom qab 4-12 teev? Yog tias tsis muaj teeb meem nrog kev teeb tsa thawj zaug, nws txhais tau hais tias tsis muaj teeb meem nrog cov kua qaub-resistant lightweight castables.
2. Tsis tas li ntawd, cov dej haus yuav tsum tau siv thaum lub sij hawm tsim kho, thiab tus nqi ntawm cov dej ntxiv yuav tsum ua raws li cov neeg tsim khoom castable cov lus qhia. Tsis txhob ntxiv dej ntau dhau. Yog tias muaj dej ntau ntxiv, qhov chaw ceev ntawm lub castable yuav raug cuam tshuam thiab lub zog yuav raug cuam tshuam.
3. Nws nyob ntawm qhov kev tsim kho thaum lub sij hawm, seb qhov kub thiab txias yog qis heev. Yog tias qhov ntsuas kub qis, kev ntsuas yuav tsum tau ua kom ntseeg tau tias qhov kev tsim kho kub tsis tuaj yeem qis dua 5 degree.
Yog tias qhov kev tsim kho kub thiab kev tsim kho nyob rau hauv qhov zoo li qub, lub teeb acid-resistant castable tseem yuav tshwm sim tsis yog condensing lossis tsis muaj zog. Nws nyob ntawm seb puas tsis muaj huab cua ncig tom qab kev tsim kho tiav. Yog tias tsis muaj huab cua ncig, lub castable yuav poob lub zog rau ob peb hnub tom qab kev tsim kho.
Yog tias tsis muaj zog, ua ntej xyuas seb cov kua qaub-resistant lub teeb castables tuaj yeem pib teeb tsa. Nias nrog koj txhais tes saib seb puas muaj cov ntiv tes rau ntawm lub castable. Yog tias muaj cov ntiv tes rau ntawm lub castable txawm tias nws tau condensed, nws txhais tau hais tias lub zog tsawg. Hauv qhov no, xyuas seb ob qhov kawg ntawm lub chimney ntawm qhov chaw tsim kho puas raug thaiv thiab tsis muaj qhov cua. Yog tias ob qhov kawg raug thaiv thiab tsis muaj qhov cua, qhov pib condensation yuav tshwm sim, tab sis yuav tsis muaj zog.
Tom qab qhov tshwm sim no tshwm sim, tshem tawm cov blockage ntawm ob qho kawg ntawm lub chimney thiab cia nws ua pa. Lwm txoj kev yog ci nws. Tom qab ci, nws yuav muaj zog, qhia tias lub teeb acid-resistant castable tsis muaj cua ncig tom qab kev tsim kho.
