Zirconia Fiber Description

Zirconia fiber ntau cov khoom muaj qhov kub thiab txias zog thiab muaj zog tiv thaiv cov tshuaj lom neeg. Zirconia fiber muaj qhov thermal conductivity qis tshaj plaws ntawm cov khoom siv refractory fiber ntau muaj nyob rau hauv khw. Qhov siab tshaj plaws ua haujlwm kub yog 2,200 degree thiab melting pib ntawm 2,500 degree (nyob ntawm cov khoom). Cov ntaub yog tsim los ntawm ib tus neeg tsis tu ncua filaments thiab tsis tas yuav cov organic binders.

Muaj ob txoj kev tsim khoom rau zirconia refractory fibers, uas yog txoj kev colloid thiab txoj kev ua ntej.

1. Txoj kev Colloid

Ntxiv glacial acetic acid rau cov tshuaj zirconium oxychloride ua rau nws hnov mob dawb zirconium acetate nag lossis daus, dehydrate thiab qhuav los ua ib tug zirconium acetate tov, ces ntxiv ib tug stabilizer (feem ntau yog YCl3), evaporate thiab mloog zoo kom lub viscosity nyob rau hauv lub Colloid. ntau yam ntawm 5-35Pa·s, qhov colloid no tuaj yeem fiberized los ntawm centrifugal spinning txoj kev los yog tshuab kom tau fiber ntau dawb paug, qhov dawb paug yog qhuav ntawm 100-110 degree kom solidify fiber, thiab ces kub-kho ntawm qhov kub thiab txias. Zirconia fiber ntau lub cev tau txais kev hloov pauv ntawm lub cev thiab tshuaj lom neeg thaum lub sijhawm kho cua sov: dej lub cev raug tshem tawm ntawm 100-110 degree ; chemically khi dej thiab organic teeb meem volatilization raug tshem tawm ntawm 200-300 degree ; zirconium ntsev pib decompose ntawm 420 degree; lub crystal transformation ntawm ZrO2 tshwm sim ntawm 800-1000 degree ; qhov kawg kub ntawm kev kho cua sov yog 1500-1600 degree .

2. Pioneer txoj kev

Soak viscose fibers (los yog saponified acetate fibers, polyester fibers, polyamide fibers, thiab lwm yam) nyob rau hauv ib tug tej yam concentration ntawm dilute hydrochloric acid los yog ethylenediamine tov kom nthuav cov fibers. Nws yog soaked nyob rau hauv ib tug aqueous tov ntawm zirconium oxychloride (los yog zirconium acetate, zirconium oxalate) muaj YCl3 stabilizer, thiaj li hais tias cov zirconium ntsev nkag mus rau hauv molecular "kav" ntawm cov organic fiber, thiab cov nto adsorption kua yog tshem tawm los ntawm centrifugation los yog extrusion. Cov organic fiber ntau lub cev ntawm zirconium ntsev yog muab tso rau hauv lub cub tawg nyob rau hauv tej yam kev mob rau kev kho cua sov, kom cov organic teeb meem yog carbonized thiab volatilized tsis hlawv. Zirconium ntsev yog decomposed rau hauv ZrO2, thiab ua nrog lub stabilizer kom stabilize ZrO2. Stable polycrystalline ZrO2 fibers tau txais.

Polycrystalline ZrO2 fiber ntau muaj hluav taws kub zoo (ZrO2 melting point yog 2590 degree), thermal conductivity tsawg, zoo tshuaj stability, thiab muaj zog corrosion kuj. Yog li ntawd, nws yog ib qho zoo heev kub thermal rwb thaiv tsev cov ntaub ntawv.

ZrO2 fiber ntau tuaj yeem ua tiav rau hauv ntau yam khoom siv fiber ntau refractory, uas tuaj yeem siv los ua cov khoom kub thiab cov khoom siv thermal rwb thaiv tsev zoo. Piv txwv li, nws yog siv rau hauv ob sab phlu ntawm ntau yam high-temperature electric furnaces, lub lim ntawm molten hlau, lub carrier ntawm high-temperature catalyst, cov khoom tiv thaiv ntawm dav hlau aircraft thiab missiles, thiab lwm yam. Qhov siab tshaj plaws kev pab cuam kub ntawm txhuas oxide refractory fiber ntau yog 1600 degree

Yttria stabilized zirconia yog ib qho hluav taws xob semiconductor ntawm qhov kub thiab txias. Cov conductivity no tshwm sim los ntawm qhov sib txawv valences ntawm ionic Zr4 ntxiv thiab Y3 ntxiv. Hluav taws xob yog ua los ntawm qhov kub siab ({2}} degree) raws li cov pa oxygen ions raug ntxias kom ntws los ntawm cov qauv zirconia ruaj khov. Qhov tshwm sim no tsim lub hauv paus ntawm zirconia oxygen sensors.

Lwm cov ntaub ntawv xws li Zirconia Felt, Zirconia Board, Zirconia Lub tog raj kheej, Zirconia Powder, Zirconia Fabric thiab Zirconia Knit kuj muaj. Thov hu rau peb kom paub meej ntxiv.
