Cov khoom siv tseem ceeb ntawm cov khoom siv hluav taws xob yog txhuas ua cov khoom siv roj muag, uas yog ib qho khoom siv hluav taws xob refractory. Raws li nws cov ntxhia muaj pes tsawg leeg, nws tuaj yeem faib ua ob pawg: gymy fibers thiab polycrystalline fibers. Cov iav fiber yog cov amorphous muaj zog fiber ntau tsim los ntawm cov kua dej ua kua thaum txias thaum txias; Cov hmoov av polycrystalline feem ntau tsim los ntawm kev txau colloidal (lossis kiv) thiab kub-reccher. Ceramic fiber ntau cov khoom tau siv dav ua rwb thaiv tsev thiab kub-resistant cov ntaub ntawv hauv ntau lub thermal kilns. Vim yog lawv lub peev xwm qis dua piv rau lwm cov ntaub ntawv regractory, lawv muaj cov khoom tso cia kub thiab pom tseeb. Ua li hauv cov ntaub ntawv hauv cov khoom siv, lawv tuaj yeem txo lub zog hauv cov hluav taws kub hauv thilns, nqa lub kiv puag ncig hauv kev txuag hluav taws xob rau thermal kilns. Ntawm qhov tod tes, nws cov ntawv thov thev naus laus zis thiab cov hau kev no tau coj tus kiv kev hloov pauv ntawm Masonry ntawm thermal kilns.
Cov xwm txheej siv tam sim no
Tej hubers thawj zaug tau tshwm sim hauv xyoo 1941, thaum cov tuam txhab Asmeskas babu thiab Wilcox Melted thiab tshuab ntuj kaolin rau hauv fibers siv hluav taws xob arc. Nyob rau lub sijhawm xyoo 1940, ob lub tuam txhab Asmeskas tau tsim txhuas silicate series fibers, uas tau ua ntej thov kev lag luam aviation; Nyob rau xyoo 1960, Tebchaws Meskas tau tsim muaj ntau yam khoom muaj fiber ntau thiab siv lawv rau cov khoom siv hauv ob sab phlu. Hauv xyoo 1970, tej hub nplej tau pib tsim thiab siv nyob rau hauv Suav teb, thiab lawv daim ntawv thov tshuab tau nce qib hauv xyoo 1980. Txawm li cas los xij, lawv qhov ntsuas kub nyob hauv qab 1000 degree, thiab cov ntawv thov thev naus laus zis yog qhov yooj yim thiab rov qab los. Tom qab nkag mus rau xyoo 1990, nrog rau kev nce qib thiab kev siv ntawm zirconium uas muaj fibers thiab polycrystalline alumers, kev ua haujlwm kub nce mus rau 1400 degree. Txawm li cas los xij, vim cov khoom ua tau zoo tsis xws luag thiab txheej txheej ua haujlwm qub, daim ntawv thov thiab cov hau kev tau txwv. Polycrystalline alumina fibers tsis tuaj yeem ua rau hauv cov pam vov pob tw, thiab cov khoom lag luam tshwj xeeb yog ib leeg, feem ntau yog cov paj rwb xoob thiab cov xaim hluav taws xob. Txawm hais tias qhov kub tau nce, lub zog yog neeg pluag, uas txwv qhov ntau ntawm kev siv thiab luv lub neej pabcuam.
Zirconium muaj cov fiber ntau yog cov siv dav dav thiab muaj tsawg tus nqi aluminium siicate fiber ntau tsim los ntawm cov txheej txheem melting. Nws tuaj yeem yog qhov dav siv los ua tag nrho cov fiber ntau hauv ob sab phlu rau qhov kub ntawm ntau yam thermal kilns. Tam sim no, qhov zoo thiab kev siv cov khoom lag luam hauv tsev hauv thaj chaw no yog qhov rov qab. Chromium muaj fiber ntau tau tshwm sim txawv teb chaws, nrog rau kev ua haujlwm siab dua li zirconium muaj cov fiber ntau, tab sis tsis muaj kev tshaj tawm hauv thaj chaw no hauv Suav teb.
