Ceramic fiber refractories, feem ntau hu ua "ceramic fiber," yog ib hom khoom siv hluav taws xob kub kub uas siv dav hauv ntau yam kev siv. Lawv tau tsim los muab cov thermal rwb thaiv tsev zoo heev, ua rau lawv yog ib qho tseem ceeb hauv cov txheej txheem kub xws li cov hlau, petrochemical, thiab iav kev lag luam.
Cov yam ntxwv tseem ceeb thiab cov khoom ntawm ceramic fiber refractories muaj xws li:
Thermal rwb thaiv tsev: Ceramic fiber refractories muaj cov thermal conductivity tsawg heev, uas txhais tau hais tias lawv muaj txiaj ntsig zoo ntawm kev tuav cov cua sov thiab tiv taus qhov kub thiab txias. Lawv tuaj yeem muab kev txuag hluav taws xob tseem ceeb los ntawm kev txo cov cua sov.
Kev Ua Haujlwm Kub Kub: Cov ntaub ntawv no muaj peev xwm tiv taus qhov kub siab tshaj 2300 degree F (1260 degree) thiab, qee zaum, txawm tias siab dua. Lawv tswj hwm lawv cov qauv kev ntseeg siab ntawm qhov kub siab, ua rau lawv zoo tagnrho rau hauv ob sab phlu, kilns, thiab lwm yam khoom siv kub.
Lub teeb yuag: Ceramic fiber ntau refractories yog lub teeb yuag, uas ua rau lawv yooj yim los lis thiab nruab. Lawv qhov ntom ntom qis kuj tseem ua rau lawv cov thermal rwb thaiv tsev zoo heev.
Tsawg Thaum Tshav Kub Cia: Lawv muaj peev xwm khaws cov cua sov tsawg, uas txhais tau tias lawv ua kom sov thiab txias sai sai. Cov yam ntxwv no tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv cov ntawv thov uas hloov pauv sai sai.
Chemical Resistance: Ceramic fiber refractories feem ntau resistant rau tshuaj corrosion, uas tso cai rau lawv siv nyob rau hauv hnyav industrial cheeb tsam.
Flexibility: Lawv tuaj yeem tsim ua ntau yam duab thiab qhov ntau thiab tsawg, suav nrog cov pam vov, boards, modules, thiab lwm yam kev cai rau cov ntawv thov tshwj xeeb.
Tsawg Thermal Expansion: Ceramic fiber ntau cov ntaub ntawv nthuav tawm tsis tshua muaj thermal expansion, uas pab tswj lawv cov qauv kev ntseeg siab ntawm qhov kub thiab txias.
Zog Efficiency: Lawv cov khoom zoo heev insulating ua rau kev txuag hluav taws xob, vim tias tsis tshua muaj cua sov poob thaum cov txheej txheem kub kub, txo cov nqi ua haujlwm.
Non-Toxic and Safe: Ceramic fiber refractories yog non-toxic thiab nyab xeeb siv, thiab lawv tsis tsim cov pa phem los yog off-gases thaum siv.
Cov refractories no feem ntau yog siv rau daim ntaub ntawv xws li hauv ob sab phlu, furnaces, thiab ncu, thiab nyob rau hauv kev tsim cov khoom xws li insulating bricks, boards, thiab gaskets. Lawv muaj nuj nqis rau lawv lub peev xwm los txhim kho kev siv hluav taws xob, tswj qhov kub thiab txias ib puag ncig, thiab txhim kho kev ua haujlwm tag nrho hauv ntau yam lag luam.
