Qhov teeb meem no peb yuav qhia ntxiv txog cov khoom siv hluav taws xob refractory uas siv rau hauv kev tsim kho rauv taws
1) Refractory fiber ntau
Refractory fiber, tseem hu ua ceramic fiber, yog ib yam ntawm cov txiv neej tsim inorganic non-metallic khoom, uas yog ib tug iav los yog crystalline theem binary compound muaj li ntawm Al2O3 thiab SiO2 ua lub ntsiab Cheebtsam. Raws li cov khoom siv hluav taws xob hluav taws xob sib sib zog nqus, nws tuaj yeem txuag hluav taws xob los ntawm 15-30% thaum siv rau hauv cov khoom siv hluav taws xob. Refractory fiber ntau muaj cov yam ntxwv zoo hauv qab no:
(1) Kub kub kuj. Kev ua haujlwm kub ntawm qhov zoo tib yam aluminium silicate refractory fiber yog 1200 ° C, thiab kev ua haujlwm kub ntawm qhov tshwj xeeb refractory fiber xws li alumina fiber thiab mullite yog siab li 1600-2000 ° C, thaum lub refractory kub ntawm cov ntaub ntawv fiber ntau xws li asbestos thiab pob zeb ntaub plaub tsuas yog hais txog 650 ° C.
(2) Thermal rwb thaiv tsev. Lub thermal conductivity ntawm refractory fiber yog tsawg heev ntawm qhov kub thiab txias, thiab thermal conductivity ntawm zoo tib yam aluminium silicate refractory fiber ntawm 1000 ° C yog 1/3 ntawm lub teeb av nplaum cib, thiab nws lub peev xwm kub yog me me, thermal rwb thaiv tsev efficiency siab. Lub thickness ntawm cov tsim rauv hauv ob sab phlu tuaj yeem raug txo los ntawm ib nrab piv nrog rau kev siv cov cib sib sib zog nqus refractory.
Qhov teeb meem tom ntej no peb yuav qhia ntxivrefractory fiber rwb thaiv tsev cov ntaub ntawvsiv rau hauv kev tsim kho rauv. Thov nyob twj ywm!
