Hauv cov xwm txheej kub siab xws li kev txuag cua sov hauv kev lag luam thiab kev rwb thaiv tsev kub hauv qhov cub, qhov zoo ntawmCov ntaub pua plag fiber ntauncaj qha txiav txim siab qhov kev nyab xeeb ntawm kev ua haujlwm ntawm cov khoom siv thiab cov nqi siv hluav taws xob. Txawm li cas los xij, qhov zoo ntawm cov khoom lag luam hauv khw sib txawv heev. Yuav ua li cas thiaj li txiav txim siab sai thiab raug qhov zoo ntawm cov pam vov ceramic fiber? Ua 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 seb qhov tsos thiab qhov ceev npaum li cas—cov pam vov ua los ntawm cov khoom siv fiber zoo yog "cov khoom zoo thaum pom thawj zaug". Cov khoom zoo muaj qhov chaw tiaj tus thiab sib npaug, tsis muaj qhov pom tseeb, tawg lossis qhov chaw tsis huv, thiab qhov faib ntawm cov fiber zoo yam tsis muaj kev sib sau ua ke. Thaum kov tes, nws zoo li mos thiab ywj, thiab tsis yooj yim rau cov khoom seem lossis tawg. Tib lub sijhawm, koj tuaj yeem piv qhov ceev los ntawm kev ntsuas qhov hnyav yooj yim—rau cov khoom uas muaj tib lub tuab, cov uas muaj qhov ceev tsim nyog (feem ntau 96-128kg / m³, nyob ntawm qhov xwm txheej ntawm daim ntawv thov) yog cov khoom ruaj khov dua thiab muaj kev ua haujlwm rwb thaiv tsev kub ruaj khov dua. Yog tias cov khoom zoo li sib dua, nyias dhau lossis muaj cov fiber xoob, nws yuav yog cov khoom tsis zoo nrog cov ces kaum txiav, uas yooj yim rau kev hloov pauv thiab poob tom qab siv ntev.
Qhov thib ob, sim qhov kev ua tau zoo tseem ceeb thiab xyuas kom tseeb tias yog qhov tseeb nrog "cov txheej txheem ua tau zoo". Kev tiv taus kub siab yog qhov qhia tseem ceeb. Cov pam vov ua los ntawm cov khoom siv fiber zoo tuaj yeem tiv taus qhov kub siab ntawm 1000-1400 ℃ (sib raug rau cov qauv khoom). Thaum yuav khoom, koj tuaj yeem thov tus neeg muag khoom kom muab cov qauv thiab ci ntug luv luv nrog lub teeb. Yog tias tsis muaj nplaim taws qhib, tsis muaj ntxhiab tsw phem, thiab tsis muaj qhov pom tseeb shrinkage lossis deformation tom qab txias, qhov kev tiv taus kub siab yeej tsim nyog. Ntawm qhov tsis sib xws, yog tias muaj pa luam yeeb, yaj lossis ntxhiab yas, nws yog cov khoom tsis tsim nyog. Tsis tas li ntawd, kev ua haujlwm rwb thaiv tsev thermal tuaj yeem txiav txim siab nrog txoj kev "ntsuas kub tes": kov daim pam uas npog qhov chaw ntawm qhov chaw cua sov nrog koj txhais tes. Yog tias qhov kub sab nraud qis thiab tsis muaj qhov pom tseeb nkag mus rau hauv cua sov, nws qhia txog kev ua haujlwm rwb thaiv tsev thermal zoo. Tib lub sijhawm, cov khoom zoo qhuav yooj yim tom qab nqus dej, thiab lawv cov kev ua tau zoo tseem tsis hloov pauv tom qab ziab, thaum cov khoom tsis zoo yuav raug kev puas tsuaj vim dej nqus.
Thaum kawg, xyuas cov ntawv pov thawj thiab cov npe kom tsis txhob muaj kev pheej hmoo nrog "kev pom zoo los ntawm cov kws tshaj lij". Cov pam vov ua los ntawm cov khoom siv fiber ntau uas tsim los ntawm cov chaw tsim khoom ib txwm muaj cov ntawv pov thawj zoo thoob ntiaj teb, xws li daim ntawv pov thawj CE thiab daim ntawv pov thawj ISO. Cov khoom hauv tsev kuj yuav tsum muaj cov ntawv qhia kev xeem GB / T. Thaum yuav khoom, koj tuaj yeem thov tus neeg muag khoom kom qhia cov ntawv pov thawj no kom tsis txhob yuav cov khoom "peb-tsis muaj" (tsis muaj chaw tsim khoom, tsis muaj hnub tsim khoom, tsis muaj daim ntawv pov thawj zoo). Tib lub sijhawm, muab qhov tseem ceeb rau cov npe uas muaj ntau xyoo ntawm kev paub txog kev lag luam. Cov lag luam zoo li no tsis yog tsuas yog muaj cov txheej txheem tsim khoom tiav, tab sis kuj muab cov khoom lag luam meej (xws li cov khoom sib xyaw, qhov kub thiab txias, kev ua haujlwm thermal) thiab kev pabcuam tom qab muag. Yog tias muaj teeb meem tshwm sim thaum siv tom qab, lawv tuaj yeem daws tau raws sijhawm. Txawm li cas los xij, cov khoom lag luam los ntawm cov chaw ua haujlwm me me feem ntau muaj cov kev cai tsis meej thiab tsis muaj kev lees paub tom qab muag. Txawm hais tias lawv zoo li pheej yig, cov nqi kho tom qab ntawd yeej siab dua.
Kev xaiv cov pam vov uas ua los ntawm cov khoom siv fiber zoo tuaj yeem txuag tau ntau dua 30% ntawm cov nqi siv hluav taws xob rau kev tsim khoom lag luam thiab ua kom lub neej ua haujlwm ntawm cov khoom siv ntev dua. Kawm paub txog cov txheej txheem ntawm kev sib txawv ntawm qhov zoo thiab qhov tsos, txheeb xyuas kev ua tau zoo, thiab xyuas kom muaj kev ntseeg siab los ntawm kev lees paub, kom txhua qhov peev nyiaj siv rau "cov ntsiab lus tseem ceeb" thiab tsim kom muaj kev nyab xeeb thiab kev rwb thaiv cua sov rau cov xwm txheej kub siab.
