Hauv kev tsim khoom lag luam thiab kev ua neej nyob txhua hnub, qhov kev thov rau siab - cov ntaub ntawv tiv thaiv kub thiab thermal rwb thaiv tsev ib txwm muaj. Raws li qhov siab -kev ua tau zoo refractory thiab thermal rwb thaiv tsev cov ntaub ntawv, ceramic fiber pam yog maj mam nyiam ntau thiab ntau xim.
Tsis ntev los no, ntawmZibo Long Keter Tshiab Khoom Co., Ltd.. nyob rau hauv Zibo, Shandong xeev, nws cov ceramic fiber pam ntau lawm kab yog ua hauj lwm ntawm tag nrho cov muaj peev xwm. Nws tau nkag siab tias cov khoom siv fiber ntau ceramic ntawm cov tuam txhab no muaj ntau yam khoom zoo heev.
Ceramic fiber ntau daim pam, tseem hu ua aluminium silicate fiber ntau daim pam, feem ntau muaj cov khoom xws li txhuas oxide. Lawv feem ntau muab faib ua ob hom: ceramic fiber tshuab pam thiab ceramic fiber spun pam. Ntawm lawv, ceramic fiber spun pam muaj ntev fiber ntau filaments, me me thermal conductivity coefficient, thiab zoo thermal rwb thaiv tsev kev ua tau zoo, thiab yog dav siv nyob rau hauv kev tsim kho ntawm feem ntau thermal rwb thaiv tsev pipelines.
Nyob rau hauv cov nqe lus ntawm cov txheej txheem ntau lawm, ceramic fiber pam yog ua los ntawm tshwj xeeb ua aluminium silicate ceramic fiber filaments thiab tsim los ntawm ib tug tshwj xeeb ob -sided needling txheej txheem. Cov txheej txheem no zoo heev txhim kho qhov kev sib tshuam ntawm cov fibers, kev tiv thaiv - delamination kev ua tau zoo, lub zog tensile, thiab qhov chaw tiaj tus. Ntxiv mus, cov pam fiber ntau tsis muaj cov organic binders, kom ntseeg tau tias zoo formability thiab stability nyob rau hauv ob qho tib si siab - kub thiab qis - kub ua hauj lwm tej yam kev mob.
Cov khoom no muaj qhov pom tseeb zoo ntawm kev ua haujlwm. Firstly, nws muaj ib tug tsawg thermal conductivity coefficient thiab tsis muaj cua sov muaj peev xwm, uas muaj peev xwm txo tau tshav kub hloov thiab lub zog noj. Thib ob, nws muaj kev ruaj ntseg tshuaj zoo heev thiab thermal stability, thiab tuaj yeem tswj kev ua haujlwm ruaj khov hauv ntau qhov chaw tshuaj lom neeg thiab siab - qhov kub thiab txias. Tsis tas li ntawd, nws muaj zog seismic tsis kam, siab tensile zog, thiab zoo heev suab haum zog, ua rau nws yog ib qho zoo heev cov khoom ntawm thermal rwb thaiv tsev thiab cov ntaub ntawv refractory. Nyob rau hauv cov nqe lus ntawm qhov kub thiab txias, nws feem ntau yuav siv tau rau lub sij hawm ntev nyob rau hauv qhov kub ntawm 950℃mus rau 1400 degree.
Nyob rau hauv daim ntawv thov teb, ceramic fiber pam tuaj yeem pom nyob txhua qhov chaw. Hauv thaj chaw aerospace, lawv tuaj yeem siv los ua cov ntaub ntawv thermal rwb thaiv tsev kom ntseeg tau tias muaj kev nyab xeeb ntawm lub dav hlau nyob hauv qhov chaw kub siab -; nyob rau hauv cov hlau thiab hlau thiab petrochemical industries, lawv yuav siv tau rau lub thermal rwb thaiv tsev ntawm high - cov khoom kub thiab kav dej; nyob rau hauv industrial furnaces, lawv yuav siv tau raws li phab ntsa linings thiab backing cov ntaub ntawv, raws li zoo raws li rau thermal rwb thaiv tsev thiab sealing ntawm expansion pob qij txha, lub qhov rooj rauv, thiab lub cub tawg sab saum toj ntawm lub cub tawg masonry; nyob rau hauv kev tsim kho kev lag luam, lawv tuaj yeem siv rau cov khoom siv hluav taws xob xws li lub qhov rooj hluav taws thiab cov ntaub thaiv hluav taws los muab kev lees paub rau lub tsev hluav taws kub nyab xeeb; nyob rau hauv automotive teb, lawv yuav siv tau raws li lub tshav kub shields rau automotive xyaw, thiab lwm yam, los txhim kho kev ua tau zoo thiab kev nyab xeeb ntawm tsheb.
Nrog rau kev nce qib ntawm cov thev naus laus zis tsis tu ncua thiab kev loj hlob tsis tu ncua ntawm kev lag luam xav tau, txoj kev loj hlob zeem muag ntawm cov ntaub pua plag ceramic yog qhov dav heev. Nyob rau hauv lub neej yav tom ntej, nws ntseeg tau hais tias ntau lub tswv yim tshiab yuav siv rau kev tsim thiab kev tshawb fawb thiab kev loj hlob ntawm ceramic fiber pam, ua rau lawv cov kev ua tau zoo tshaj thiab lawv daim ntawv thov teb ntau dua, muab kev txhawb zog rau txoj kev loj hlob ntawm ntau yam industries.
