Refractory fiber, tseem hu ua ceramic fiber, yog tam sim no cov khoom siv refractory nrog qis tshaj thermal conductivity thiab thermal rwb thaiv tsev zoo tshaj plaws thiab lub zog txuag hluav taws xob ntxiv rau cov khoom siv nano.Nws muaj ntau yam zoo, xws li lub teeb yuag, kub tsis kam, zoo thermal rwb thaiv tsev nyhuv, yooj yim siv, thiab lwm yam.Piv nrog rau cov tsoos refractory bricks, refractory castables thiab lwm yam ntaub ntawv, ceramic fiber folding blocks muaj cov nram qab no kev ua tau zoo:

a) Lub teeb yuag (txo kom lub cub tawg thiab txuas lub neej ntawm lub cub tawg): refractory fiber yog ib hom fiber ntau refractory khoom.Feem ntau siv refractory fiber ntau daim pam muaj qhov ntim ceev ntawm 96 ~ 128kg / m3, thaum lub ntim ntim ntawm refractory fiber ntau quav los ntawm daim pam fiber ntau yog nruab nrab ntawm 200 ~ 240kg / m3, thiab qhov hnyav yog 1/5 ~ 1 / 10 ntawm lub teeb refractory cib los yog amorphous khoom, thiab 1/15 ~ 1/20 ntawm cov khoom hnyav refractory.Nws tuaj yeem pom tias cov khoom siv hluav taws xob hluav taws xob refractory tuaj yeem paub lub teeb yuag thiab ua haujlwm siab rau cua sov, txo cov khoom siv hluav taws xob thiab ua kom lub neej ntev.

b) Tsawg tshav kub muaj peev xwm (tsawg tshav kub nqus thiab ceev kub nce): Lub peev xwm kub ntawm lub cub tawg yog feem ntau proportional rau qhov hnyav ntawm lub qhov cub hauv ob sab phlu.Tsawg tshav kub muaj peev xwm txhais tau hais tias lub cub tawg absorbs tsawg dua thaum lub sij hawm reciprocating ua hauj lwm, thiab cov cua kub ceev yog ceev.Lub peev xwm kub ntawm ceramic fiber tsuas yog 1/10 ntawm lub teeb hluav taws xob tiv thaiv hauv ob sab phlu thiab lub teeb refractory cib, uas zoo heev txo cov kev siv hluav taws xob hauv qhov cub ua haujlwm kub tswj.Tshwj xeeb tshaj yog rau cov cua sov rauv nrog kev ua haujlwm tsis sib xws, nws muaj kev txuag hluav taws xob tseem ceeb heev

c) Tsawg thermal conductivity (tsawg tshav kub poob): thaum nruab nrab kub ntawm cov khoom siv fiber ntau ceramic yog 200C, thermal conductivity tsawg dua 0. 06W / mk, tsawg dua 0 ntawm 400 ° ntawm qhov nruab nrab.10W / mk, txog 1/8 ntawm cov khoom siv hluav taws kub-resistant amorphous, thiab txog 1/10 ntawm lub teeb ci ci, thaum lub thermal conductivity ntawm ceramic fiber ntau thiab cov khoom hnyav hluav taws kub-resistant tuaj yeem tsis quav ntsej.Yog li ntawd, thermal rwb thaiv tsev nyhuv ntawm refractory fiber cov ntaub ntawv tseem ceeb heev.

d) Kev tsim kho yooj yim (tsis tas yuav tsum muaj kev sib koom ua ke): cov neeg ua haujlwm tsim kho tuaj yeem ua haujlwm tom qab kev cob qhia yooj yim, thiab kev cuam tshuam ntawm kev tsim kho cov yam ntxwv ntawm cov thermal rwb thaiv tsev cov nyhuv ntawm lub qhov cub hauv ob sab phlu.

e) Kev siv ntau yam: Nrog rau kev tsim khoom thiab kev siv thev naus laus zis ntawm cov khoom siv hluav taws xob refractory, cov khoom siv hluav taws xob refractory ceramic tau pom tau hais tias serialization thiab functionalization, thiab cov khoom tuaj yeem ua tau raws li qhov yuav tsum tau siv ntawm cov qib sib txawv ntawm 600 ° C txog 1400 ° C. Los ntawm cov yam ntxwv ntawm morphology, nws tau maj mam tsim ntau yam kev ua haujlwm thib ob lossis cov khoom siv sib sib zog nqus los ntawm cov tsoos ceramic fiber paj rwb, ceramic fiber pam, fiber ntau cov khoom rau refractory fiber module, ceramic fiber board, ceramic fiber profiled khoom, ceramic fiber ntawv, fiber ntau textiles thiab lwm yam ntaub ntawv.Nws tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob sib txawv hauv ntau qhov kev lag luam rau cov khoom siv hluav taws xob refractory ceramic.

f) Thermal shock resistance: fiber ntau folding module muaj kev tiv thaiv zoo heev rau qhov kub thiab txias hloov pauv.Ntawm qhov chaw uas cov khoom siv cua sov tuaj yeem dais nws, fiber ntau folding module rauv hauv ob sab phlu tuaj yeem ua kom sov lossis txias ntawm txhua qhov ceev.

o) Kev ua haujlwm tsis zoo rau kev sib txhuam (nrog kev yooj yim thiab elasticity): daim pam fiber ntau lossis daim pam fiber ntau yog hloov tau thiab elastic, thiab tsis yooj yim rau kev puas tsuaj.Tag nrho lub cub tawg tom qab kev teeb tsa tsis yooj yim rau kev puas tsuaj thaum nws cuam tshuam los yog vibrated los ntawm kev thauj mus los

h) Tsis muaj qhov cub kom qhuav: yam tsis muaj qhov cub kom qhuav cov txheej txheem (xws li kev kho, ziab, ci, txheej txheem ziab kom qhuav thiab tiv thaiv kev tiv thaiv hauv huab cua txias), lub tshuab hluav taws xob tuaj yeem siv tom qab tsim kho.

1) Lub suab rwb thaiv tsev zoo (txo qis suab nrov): ceramic fiber ntau folding thaiv tuaj yeem txo cov suab nrov nrov nrog zaus tsawg dua 1000 Hz.Rau lub suab tsis muaj zaus tsawg dua 300 Hz, lub suab rwb thaiv tsev muaj peev xwm zoo dua rau cov khoom siv suab rwb thaiv tsev, thiab tuaj yeem txo cov suab nrov nrov.

j) Muaj zog tsis siv neeg tswj muaj peev xwm: lub siab thermal rhiab heev ntawm ceramic fiber hauv ob sab phlu tuaj yeem hloov mus rau qhov tsis siv neeg tswj cov cua sov cua sov.

k) Kev ruaj ntseg tshuaj: cov khoom siv tshuaj lom neeg ntawm ceramic fiber folding thaiv yog ruaj khov.Tsuas yog phosphoric acid, hydrofluoric acid thiab muaj zog alkali, lwm yam acids, alkalis, dej, roj thiab chav tsis eroded.
