Feem ntau yog hais txog cov khoom siv tawv tawv refractory fiber ntau uas muaj cov khoom siv tsis zoo lossis cov organic binders. Lub binder yog ib yam khoom ntxiv rau cov khoom tsis yog yas los yog cov khoom siv fiber ntau los muab kev ua haujlwm zoo, lub zog loj lossis lub zog ziab.
Lub npe hu ua refractory fiber yog hais txog cov khoom siv dag zog uas tsim nyog rau ntau tshaj 800 degree raws li cov khoom siv hluav taws xob. Fiberglass board muaj cov yam ntxwv hauv qab no:
1. Classification kub.
Kev faib tawm qhov kub yog hais txog qhov kub siab tshaj plaws uas cov kab shrinkage tsawg dua tus nqi muab, qhia nyob rau hauv degree C thiab sib cais los ntawm 50 degree C. Cov cua sov mus tas li hloov kab ntawm refractory fiber ntau yog txiav txim los ntawm GB / T{{1} }. Lub shrinkage tus nqi ntawm refractory fiber board thiab tshwj xeeb-zoo li cov khoom nyuaj yog tsis ntau tshaj 2 feem pua, uas yog, kev faib ua feem kub. Hauv GB / T3003-2006 "Refractory Ceramic Fibers thiab cov khoom", qhov kev faib tawm kub ntawm ceramic fibers thiab cov khoom muab faib ua 19 qib, los ntawm 850 degree mus rau 1750 degree .
Qhov kev faib tawm kub sawv cev rau qhov ntsuas kub tsis kam ntawm cov khoom siv hluav taws xob refractory, uas yog qhov kev ua tau zoo tshaj plaws los xyuas kom meej tias kev siv cov khoom siv hluav taws xob refractory ceramic fiber board.
2. Ntim ceev.
Volume density yog hais txog qhov sib piv ntawm qhov ziab ntawm cov fiberboard rau nws qhov ntim tag nrho. Raws li ib txwm muaj, qhov ntim ceev ntawm fiberboard nyob rau hauv thaj tsam ntawm 200kg / m3, GB / T 3003-2006 "Refractory ceramic fibers thiab cov khoom", lub ntim ntom ntom ntawm fiberboard nominal 260, 280, 300, 320, 340, 360 380, 400kg / m3.
3. Compressive zog.
Hais txog qhov kawg thauj khoom uas cov khoom siv fiber ntau tuaj yeem dais ib cheeb tsam ntawm chav tsev kub. Compressive zog yog ib qho tseem ceeb Performance indexes los ntsuas qhov zoo ntawm cov khoom siv fiber ntau, uas tuaj yeem cuam tshuam ncaj qha rau lub koom haum cov qauv ntawm cov khoom, xws li compactness, uniformity, sinter, thiab lwm yam.
Hloov cov cua sov mus tas li.
Cov ntaub ntawv refractory nyob rau hauv qhov tsis muaj sab nraud quab yuam, cua sov rau qhov ntsuas kub, tuav rau ib lub sijhawm, txias rau chav tsev kub tom qab residual linear expansion lossis contraction. Cov txiaj ntsig ntawm kev tshawb fawb hauv tsev thiab txawv teb chaws qhia tau hais tias qhov kev ntsuam xyuas hluav taws xob hloov hluav taws xob ntawm cov khoom siv fiber ntau yuav tsum tau rwb thaiv tsev rau 24 teev, thiab qhov shrinkage tus nqi ntawm cov khoom fiber ntau tom qab 24 teev ntawm kev ntsuas rwb thaiv tsev mus txog ntau dua 75 feem pua ntawm cov shrinkage tus nqi. cov khoom siv fiber ntau tom qab siv mus ntev. Cov kev ntsuas shrinkage ntawm cov cua sov xaim rau 24 teev tuaj yeem siv los sawv cev rau kev hloov pauv ntawm cov khoom siv hluav taws xob mus tas li thaum siv cov khoom siv mus ntev.
