Nyob rau hauv high-temperature scenarios xws li industrial tshav kub preservation thiab kiln tshav kub rwb thaiv tsev, qhov zoo ntawmceramic fiber pamncaj qha txiav txim siab txog kev nyab xeeb ntawm cov khoom siv thiab cov nqi siv hluav taws xob. Txawm li cas los xij, qhov zoo ntawm cov khoom ntawm kev ua lag luam txawv heev. Yuav ua li cas sai thiab raug txiav txim zoo ntawm ceramic fiber pam? Tus tswv 3 qhov tseem ceeb hauv qab no kom yooj yim zam kev nkag siab yuam kev hauv kev yuav khoom ..
Ua ntej, xyuas cov tsos thiab qhov ntom ntom-cov ntaub pua tsev zoo nkauj ceramic yog "cov khoom zoo thaum pom thawj zaug". Cov khoom lag luam zoo muaj qhov tiaj tus thiab tsis sib xws, tsis muaj qhov pom tseeb, tawg lossis qhov chaw tsis huv, thiab cov khoom siv fiber ntau yog qhov zoo yam tsis muaj agglomeration. Thaum kov los ntawm tes, nws zoo nkaus li mos thiab elastic, thiab tsis yooj yim rau tso cov residues los yog tawg. Nyob rau tib lub sijhawm, koj tuaj yeem sib piv qhov ceev los ntawm kev hnyav yooj yim - rau cov khoom ntawm tib lub thickness, cov uas muaj peev xwm ceev (feem ntau 96-128kg / m³, nyob ntawm seb daim ntawv thov scenario) yog ntau ruaj thiab muaj kev ruaj ntseg thermal rwb thaiv tsev kev ua tau zoo. Yog tias cov khoom xav tias lub teeb dhau, nyias dhau los yog muaj cov fibers xoob, nws yuav yog cov khoom tsis zoo nrog cov fab txiav, uas yog qhov ua rau deformation thiab poob tawm tom qab siv mus ntev.
Qhov thib ob, sim qhov tseem ceeb ntawm kev ua tau zoo thiab txheeb xyuas qhov tseeb nrog "cov tswv yim siv tau". High-temperature resistance yog ib qho tseem ceeb qhia. High-zoo ceramic fiber pam tuaj yeem tiv taus qhov kub thiab txias ntawm 1000-1400 ℃ (raws li cov qauv khoom). Thaum yuav khoom, koj tuaj yeem nug tus neeg muag khoom kom muab ib qho qauv thiab luv luv ci ntawm ntug nrog lub sib dua. Yog tias tsis muaj nplaim taws, tsis muaj ntxhiab tsw, thiab tsis muaj qhov pom tseeb shrinkage lossis deformation tom qab txias, qhov kub-kub kuj yog qhov tsim nyog. Ntawm qhov tsis sib xws, yog tias muaj pa luam yeeb, yaj lossis ntxhiab tsw ntxhiab, nws yog cov khoom tsis tsim nyog. Tsis tas li ntawd, kev ua haujlwm thermal rwb thaiv tsev tuaj yeem raug txiav txim nrog "kev ntsuas kub ntawm tes" txoj kev: kov daim pam npog qhov chaw ntawm lub tshav kub nrog koj txhais tes. Yog hais tias qhov kub ntawm sab nraud yog tsawg thiab tsis muaj qhov pom tseeb thaum tshav kub kub nkag, nws qhia tau hais tias zoo thermal rwb thaiv tsev nyhuv. Nyob rau tib lub sijhawm, cov khoom lag luam zoo qhuav yooj yim tom qab nqus dej, thiab lawv qhov kev ua tau zoo tsis hloov pauv tom qab ziab, thaum cov khoom tsis zoo tuaj yeem raug kev puas tsuaj vim kev nqus dej.
Thaum kawg, tshawb xyuas cov ntawv pov thawj thiab cov npe kom tsis txhob muaj kev pheej hmoo nrog "kev pom zoo tshaj lij". Ceramic fiber ntau daim pam tsim los ntawm cov tuam txhab tsis tu ncua yuav muaj cov ntawv pov thawj zoo thoob ntiaj teb, xws li daim ntawv pov thawj CE thiab ISO daim ntawv pov thawj. Cov khoom lag luam hauv tsev kuj tseem yuav tsum muaj GB / T cov ntaub ntawv ntsuas tus qauv. Thaum yuav khoom, koj tuaj yeem nug tus neeg muag khoom kom qhia cov ntawv pov thawj no kom tsis txhob yuav "peb-tsis muaj" (tsis muaj chaw tsim khoom, tsis muaj hnub tsim khoom, tsis muaj daim ntawv pov thawj zoo) cov khoom. Nyob rau tib lub sijhawm, ua qhov tseem ceeb rau cov hom lag luam nrog xyoo dhau los ntawm kev lag luam. Xws li kev lag luam tsis tsuas yog muaj cov txheej txheem tsim khoom lag luam, tab sis kuj muab cov khoom lag luam tsis meej (xws li muaj pes tsawg leeg, qhov kub thiab txias, thermal conductivity) thiab kev pab cuam tom qab muag. Yog tias muaj teeb meem tshwm sim thaum siv tom ntej, lawv tuaj yeem daws tau raws sijhawm. Txawm li cas los xij, cov khoom lag luam los ntawm kev cob qhia me me feem ntau muaj qhov tsis meej thiab tsis muaj kev lees paub tom qab muag. Txawm hais tias lawv zoo li pheej yig, cov nqi kho mob tom qab tau siab dua.
Xaiv cov pam zoo nkauj ceramic fiber ntau tuaj yeem txuag tau ntau dua 30% ntawm cov nqi siv hluav taws xob rau kev tsim khoom thiab txuas ntxiv lub neej kev pab cuam ntawm cov khoom siv. Master cov txheej txheem ntawm kev paub qhov txawv ntawm qhov zoo li, txheeb xyuas qhov ua tau zoo, thiab ua kom muaj kev ntseeg siab los ntawm cov ntawv pov thawj, yog li txhua qhov peev nyiaj siv rau "cov ntsiab lus tseem ceeb" thiab cov khoom muaj kev nyab xeeb thiab cov rwb thaiv tsev kub yog tsim rau cov xwm txheej kub.
