Low-end ceramic fiber ntau daim ntawv thov
Ceramic fiber yog cov khoom siv hluav taws xob zoo thiab cov khoom siv thermal rwb thaiv tsev, uas ua tau raws li cov kev xav tau ntawm cov kev lag luam hauv qab rau "ntau zog-txuag, ntau tus phooj ywg ib puag ncig, thiab kev nyab xeeb dua". Tam sim no, cov khoom tsim tawm txhua xyoo ntawm cov khoom siv hluav taws xob hauv tsev yog li 700, 000 tons, suav txog li 2.9 feem pua ntawm cov khoom siv refractory. Lub hauv paus yog me me, thiab yav tom ntej Kev nthuav dav ntawm txhua daim ntawv thov subdivided yuav ua rau muaj kev loj hlob ntau dua. Cov khoom siv fiber ntau ceramic tsis yog cov khoom lag luam tsim nyog. Nws yog ib qho tsim nyog los kho cov khoom xyaw, txheej txheem thiab kev txhawb nqa thaum siv hauv ntau qhov chaw. Yog li ntawd, daim ntawv thov ntawm qhov tsis yog tus qauv tau nthuav dav nrog txoj kev loj hlob ntawm tag nrho cov kev lag luam.
A: Cov khoom siv hluav taws xob kub kub
Ceramic fiber ntau yog cov khoom siv hluav taws xob txuag hluav taws xob zoo. Cov khoom siv nws tus kheej muaj cov yam ntxwv ntawm cov fibers zoo tib yam, thiab tib lub sijhawm muaj qhov kub thiab txias, tiv thaiv corrosion thiab oxidation tsis kam uas zoo tib yam fibers tsis muaj. Qhov tseem ceeb tshaj, nws zam qhov brittleness ntawm cov khoom siv refractory. Rau qee qhov, nws hloov cov tsoos hnyav refractory cib thiab siv los ua cov khoom siv hauv ob sab phlu rau kev lag luam kilns. Qhov txiaj ntsig loj tshaj plaws ntawm kev lag luam kiln ua nrog ceramic fiber ntau li cov phab ntsa kiln yog lub zog txuag. Piv txwv li: Polycrystalline mullite fiber ntau cov khoom siv tuaj yeem siv los ua cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob kub hauv qab 1600 degree ntev, xws li silicon carbide hluav taws xob furnaces, molybdenum silicide electric furnaces, ntau yam steel cua sov furnaces, mechanical forging furnaces, thiab lwm yam, uas tuaj yeem txhim kho Lub thermal efficiency ntawm cov cuab yeej siv tau zoo heev txuag lub zog, ua kom cov khoom tsim tau thiab txhim kho cov khoom zoo. Nws tuaj yeem siv rau kev rwb thaiv tsev kub ntawm ntau yam kub-kub industrial kilns; ceramic kiln; mechanical thiab metallurgical cua sov rauv; Thaum tshav kub kub kho rauv thiab lwm yam muaj kiln kub nto linings; hluav taws kub kub thiab hluav taws kub rwb thaiv tsev; kiln qhov rooj, kiln tsheb, expansion pob qij txha, thiab lwm yam ntaub ntawv rwb thaiv tsev; iav kiln rwb thaiv tsev.
B lim khoom
Vim nws lub zog siab, zoo thermal poob siab tsis kam, thiab tshuaj tiv thaiv corrosion, cov ntaub ntawv fiber ntau ceramic tau dav siv hauv huab cua purification, high-temperature flue gas filtration, diesel engine exhaust microfiltration capture, chemical filtration, and molten metal filtration. Ceramic fiber ntau lim tuaj yeem muab faib ua cov khoom siv fiber ntau hauv cov khoom siv, cov ntaub ntawv fiber ntau ceramic, ceramic inner net (dawb), thiab ceramic fiber lim lub cev.
C suab-absorbing thiab suab-insulating cov ntaub ntawv
Cov khoom siv fiber ntau yog cov ntxeem tau ntawm cov fibers zoo, uas muaj suab nrov zoo thiab lub suab rwb thaiv tsev. Ua ntej tshaj plaws, vim tias cov khoom fiber ntau nws tus kheej muaj ntau qhov me me txuas ntawm cov fibers, thaum lub suab nthwv dej yog qhov tshwm sim ntawm cov khoom siv fiber ntau thiab nthuav tawm hauv nws, qhov viscous tsis kam ntawm huab cua hauv qhov pores thiab kev sib txhuam ntawm cov fibers yuav Ib feem ntawm lub suab zog yog hloov mus rau hauv lub zog hluav taws xob los ua qhov poob.
D Daim ntawv thov ntawm cov khoom siv fiber ntau ceramic
Daim ntawv thov ntawm advanced ceramic fiber yog txawv ntawm cov tsoos ceramic fiber. Lub ntsiab lus tseem ceeb yog tias raws li cov yam ntxwv ntawm fiber ntau nws tus kheej, ntxiv rau kev siv nws qhov kub thiab txias tsis kam, rwb thaiv tsev kub thiab hluav taws kub, nws kuj tseem ua rau nws cov yam ntxwv ua haujlwm zoo, xws li nws tus kheej yoj nqus. kuj, corrosion kuj, huab cua tsis kam, thiab lwm yam.
Ceramic fiber nws tus kheej yog ib qho khoom siv hluav taws xob thiab yog cov khoom tseem ceeb rau radar yoj nqus. Nws kuj muaj cov khoom siv zoo tshaj plaws xws li lub cev nyhav, lub zog siab, siab kub tsis kam, thiab oxidation kuj. Los ntawm kev hloov cov qauv siv lead ua los ntawm cov txheej txheem kev npaj, qhov kev tiv thaiv ntawm fiber ntau tuaj yeem hloov kho, thiab tom qab ntawd ntau txheej kom ua tiav lub hom phiaj ntawm kev nqus thiab xa cov nthwv dej. Ceramic fiber reinforced composites tuaj yeem ncaj qha npaj stealth structural qhov chaw, uas muaj zog dua thiab kub tsis kam tshaj qhov stealth txheej. F-22 siv cov khoom siv hauv cov khoom siv zais cia nyob ze ntawm tus Tsov tus tw; tus Tsov tus tw ntawm Fabkis APTGD missile yog tsim los ntawm hexagonal me me ntawm ceramic yoj-absorbing khoom, uas muaj ib tug zoo yoj-absorbing nyhuv; US Air Force tau tsim Si3N4 broadband pob tshab Wave radome.
