Rau kev lag luam xws li ceramics manufacturing thiab steel ntau lawm, yuav ua li cas zoocov ntaub ntawv refractoryua nyob rau hauv huab cua kub tsis yog ib qho kev nthuav dav me xwb- nws yog ib qho tseem ceeb rau kev nyab xeeb ntawm kev ua haujlwm, kev siv hluav taws xob, thiab cov khoom zoo. Ntawm qhov dav ntawm qhov siab - qhov kub thiab txias kev xaiv,ceramic fiber rwb thaiv tsevyog ib qho kev mus- rau kev xaiv rau ntau tus engineers thiab tus thawj tswj kev yuav khoom.
Tab sis tsuas yog qhov zoo npaum li cas cov khoom no sawv mus rau huab cua kub? Cia peb rhuav tshem cov kev tshawb fawb, cov ntaub ntawv ua tau zoo, thiab qhov tiag - ntiaj teb siv uas ua rau nws ua tus thawj coj hauvcub refractorythiab industrial rwb thaiv tsev.
Kev Tshawb Fawb Tom Qab Ceramic Fiber Rwb Thaiv Tsev Siab -Tsub Ua Haujlwm
Qhov zais cia tom qabceramic fiber rwb thaiv tsev's zoo heev tshav kub kuj nyob rau hauv nws cov cim pleev thiab qauv. Nws yog tsim los ntawm siab-purity alumina (Al₂O₃) thiab silica (SiO₂) - cov ntaub ntawv melted ntawm qhov kub siab heev (feem ntau tshaj 2000 degree) thiab ces tig mus rau hauv zoo, interlocking fibers siv txoj kev xws li tshuab los yog spinning. Cov qauv fibrous no tsim ntau lab lub hnab ntim cua me me uas ntsuas cua sov, thaum lub alumina -silica puag ib txwm tiv thaiv kev puas tsuaj los ntawm qhov kub thiab txias.
Tsis zoo li cov pob zeb refractory uas vam khom qhov ceev los thaiv cov cua sov, ceramic fiber ntau lub teeb yuag, ntxeem tau tsim muaj ob qhov zoo: nws txo qis ntawm kev hloov hluav taws xob los ntawm kev sib txuas thiab hluav taws xob, thiab nws txo qhov hnyav ntawm cov khoom siv xws li kilns thiab furnaces. Dab tsi ntxiv, siab -zooceramic fiber rwb thaiv tsevtsis muaj cov organic binders, yog li nws yuav tsis tso cov pa roj los yog poob lub zog ntawm cov qauv txawm tias raug kub kub tas li.
Tiag -Kev Ua Haujlwm Kub Kub Ntiaj Teb: Tus lej Qhov Tseem Ceeb
Thaum ntsuascov ntaub ntawv refractory, "siab-kub tsis kam" tsis yog qhov kev thov khoob - nws tau txhais los ntawm kev ntsuas ntsuas tau zoo li kev siv qhov kub thiab txias siab siab.Ceramic fiber rwb thaiv tsevua tau zoo heev nyob rau ntau qib:
- Standard qib (1260 degree):Feem ntau siv hom, zoo meej rau kev lag luam kilns thiab kho cua sov qhov cub. Cov khoom no nyob ruaj khov thaum siv tsis tu ncua ntawm qhov kub thiab txias txog 1260℃thiab tuaj yeem ua haujlwm luv luv -lub sij hawm peaks ntawm 1400℃. Qhov ntawd ua rau lawv zoo tagnrhocub refractoryxaiv rau ceramic thiab iav manufacturing.
- High- qib kev ua tau zoo (1400℃-1649 degree):Rau ib puag ncig hnyav dua - xws li kev sim tshuaj aerospace lossis qib siab steel smelting - qib nrog cov ntsiab lus alumina siab dua (txog 72%) ua haujlwm tsis tu ncua ntawm 1400℃txog 1500℃. Qee qhov tshwj xeeb versions txawm tias qhov kub siab tshaj plaws txog 1649 degree. Cov qib no feem ntau suav nrog cov khoom siv ntxiv xws li zirconia (ZrO₂) los txhawb kev ruaj ntseg thermal.
- Thermal shock resistance:Tshaj li ruaj khov-kev ua haujlwm kub,ceramic fiber rwb thaiv tsevtswj kev kub ceev hloov pauv (los ntawm kev pib txias mus rau 1000℃+ nyob rau hauv cov xuab moos) tsis muaj cracking lossis tev. Qhov no yog qhov tseem ceeb rau cov cuab yeej uas ua kom sov thiab txias tsis tu ncua, xws li batch- txheej txheem kilns.
Ceramic Fiber Blanket: Ib Lub Hnub Qub Ntau Yam hauv High -Tsuas Siv Tau
Ntawm cov ntawv sib txawv ntawmceramic fiber rwb thaiv tsev, ceramic fiber daim pamsawv tawm rau kev sib npaug ntawm kev ua tau zoo thiab kev ua tau zoo. Ua nrog ob npaug -sab koob xuas nrig ntaus, nws tau txhim kho tensile lub zog thiab tiv thaiv txheej txheej sib cais - uas ua rau nws yooj yim rau nruab rau ntawm qhov nkhaus lossis qhov tsis sib xws xws li kiln linings thiab phab ntsa rauv.
Cov txiaj ntsig tseem ceeb ntawmceramic fiber daim pamnyob rau hauv siab - qhov kub thiab txias muaj xws li:
- Tsawg thermal conductivity:Ntawm 800 degree, nws cov thermal conductivity tsawg li 0.16 W / mK - qis dua li ib txwmcov ntaub ntawv refractory. Qhov ntawd txhais tau 20-30% kev txuag hluav taws xob rau kev lag luam.
- Durability:Nws tiv taus cov tshuaj corrosion (xws li cov kua qaub thiab alkalis) thiab kev vibration, tswj kev ua tau zoo rau 5-10 xyoo nyob rau hauv ib puag ncig muaj kev lag luam - ntev tshaj li ntau qhov kev sib tw rwb thaiv tsev.
- Kev kho yooj yim:Nws qhov yooj yim tso cai rau kev kho sai lossis hloov pauv, txo qis sijhawm rau cov khoom siv tseem ceeb xws li petrochemical reactors thiab steel furnaces.
