Refractory tej yam khoom yog ib hom khoom siv tsis tu ncua nrog cov qauv siv hluav taws xob ntau. Cov stacking ntawm fibers yog random thiab tsis sib haum, thiab tus qauv geometric no ua rau muaj kev sib txawv ntawm lawv lub cev.
Fiber ntau
Ib tus refractory tej hub melting txheej txheem, qhov ceev ntawm cov fibers tuaj yeem raug suav tias yog tib yam li qhov tseeb ntom ntom. Thaum lub qhov kub qhia kub yog 1260, qhov ceev ntawm refractory fibers yog 1400 ℃, qhov ceev ntawm refractory tej hub fiber yog 2.8g / cm3. Cov polycrystalline ua los ntawm txhuas oxide muaj qhov sib txawv tiag tiag vim muaj micro pores ntawm lub microcrystalline tshaj tawm sab hauv cov fibers.
Fiber diam
Cov co cheeb tsam ntawmRefractory Ceramic Fiberstsim los ntawm kev kub ntxhov yaj txhaj tshuaj moulding txoj kev sib xws los ntawm 2.5 txog 3.5 μ m. Cov cheeb tsam ntxig ntawm cov refractory tej hub fibers tsim los ntawm kev kub ceev ceev spinning txoj kev yog 3-5 μ m. Txoj kab uas hla tsis yog ib txwm nyob hauv cov kab no, thiab feem ntau cov fibers yog ntawm 1-8 μm. Txoj kab uas cov cheeb tsam sib xyaw ua ke cuam tshuam rau lub zog thiab thermal condactivity ntawm refractory fiber ntau cov khoom lag luam. Thaum cov cheeb tsam uas muaj fiber ntau yog qhov loj, lub refractory fiber ntau cov khoom siv nyuaj thaum kov lub zog kuj tseem nce cov thermal conductivity. Hauv refractory fiber ntau cov khoom, lub thermal conductivity thiab lub zog ntawm cov fibers yog qhov tseem ceeb tshaj tawm. Qhov nruab nrab lub taub ntawm Alumina Polycrystalline feem ntau yog feem ntau 3 μ m. Txoj kab uas hla ntawm feem ntau ntawm cov refractory tej hub txhuv yog ntawm 1-8 μ.
