Refractory fiber, tseem hu ua ceramic fiber, yog ib hom tshiab ntawm fiber ntau zoo li cov khoom siv kub-resistant.Txawm li cas los xij, cov ntxhia hmoov av ntawm ntau cov fibers tuaj yeem tsim cov tshuaj biochemical muaj zog nrog cov kab mob lom, uas tsis yog tsuas yog ua rau tib neeg noj qab haus huv xwb, tab sis kuj ua rau muaj kev phom sij rau ib puag ncig.
Nyob rau hauv xyoo tas los no, tib neeg tau txuas qhov tseem ceeb rau kev tsim cov fiber ntau tshiab, thiab qhia cov khoom xws li Cao, Mgo, BZo3, thiab Zr02 rau hauv cov khoom siv fiber ntau.Raws li kev sim ua pov thawj, alkaline ntiaj teb silicate fiber ntau nrog Cao, Mgo, thiab Site02 raws li cov khoom tseem ceeb yog cov fiber ntau soluble.Bio-soluble refractory fiber muaj qee yam solubility hauv tib neeg lub cev kua, txo kev puas tsuaj rau tib neeg kev noj qab haus huv, thiab tuaj yeem siv tsis tu ncua ntawm qhov kub siab dua.Cov khoom siv fiber ntau.Txhawm rau txhim kho cov cua sov ua haujlwm ntawm cov kuab tshuaj fiber ntau, cov txheej txheem ntawm kev qhia Zr02 Cheebtsam yog saws los txhim kho cov tshav kub tsis kam ntawm soluble fiber.
Nyob rau hauv tus txheej txheem ntawm kev tshawb fawb bio-soluble ceramic fibers, ntau lub teb chaws muaj lawv tus kheej patents ntawm cov muaj pes tsawg leeg.soluble ceramic fibers.Kev sib txuas ntau yam patents ntawm Tebchaws Meskas thiab Lub Tebchaws Yelemees ntawm cov khoom siv hluav taws xob soluble ceramic, cov hauv qab no muaj pes tsawg leeg (los ntawm qhov hnyav feem pua) yog featured:
①Si02 45-65% Mg0 0-20% Ca0 15-40% K2O + Na2O 0-6%
②Si02 30-40% A1203 16-25% Mg0 0-15% KZO+NazO 0-5% P205 0-0.8%
Los ntawm cov patents thiab cov muaj pes tsawg leeg ntawm ntau yam soluble fibers nyob rau hauv kev ua lag luam, peb paub tias tam sim no soluble refractory fiber yog ib yam tshiab ntawm refractory fibers.Nws cov khoom tseem ceeb yog txawv heev los ntawm cov tsoos fibers.Nws lub ntsiab Cheebtsam yog nyob rau hauv lubmagnesium-calcium-silicon system, magnesium-silicon system thiab calcium-aluminium-silicon system.
Kev tshawb fawb txog bio-degradable cov ntaub ntawv feem ntau tsom rau ob qhov kub kub:
① Kev tshawb fawb txog bio-compatibility thiab bio-activity ntawm biodegradable cov ntaub ntawv;
② Kev tshawb fawb ntawm cov txheej txheem degradation thiab cov txheej txheem metabolic ntawm biodegradable cov ntaub ntawv hauv lub cev.
Soluble ceramic fiber ntautuaj yeem hloov qee cov tsoos ceramics fibers.Kev siv tas li kub ntawm soluble ceramic fiber tuaj yeem ncav cuag 1260 ℃.Nws kuj muaj kev ua haujlwm zoo thermal rwb thaiv tsev thiab kev nyab xeeb siv dav dav.Yog tias nqus tau rau hauv lub ntsws, nws tuaj yeem yaj sai sai hauv lub ntsws cov kua dej thiab yooj yim tawm ntawm lub ntsws, uas yog, nws muaj kev pheej hmoo tsawg heev.
Soluble ceramic fiberstau ua rau ntau yam duab thiab siv nyob rau hauv ntau qhov chaw kub.Lub tshuab nqus tsev tuaj yeem ua rau cov fibers rau hauv ntau yam duab nrog rau cov raj, rings, composite molding combustion chambers, thiab lwm yam. Txhawm rau ua kom zoo dua qhov kev ua tau zoo ntawm cov ceramic fibers hauv kev siv, cov khoom siv fiber ntau tuaj yeem txiav lossis tsis tau.Soluble ceramic fiber felts thiab fiber blocks tau siv nyob rau hauv ntau qhov chaw kub kub, xws li ceramic kilns, hlau thiab txhuas rauv, thiab lwm yam. Lawv tuaj yeem siv rau hauv ethylene furnaces hauv kev lag luam petrochemical, thiab muaj kev siv zoo tib yam li cov tsoos. ceramic fibers.
