Thaum peb mus xaiv cov khoom siv fiber ntau ceramic, peb yuav nkag siab qee cov ntaub ntawv ntawm cov khoom thiab xyuas cov ntaub ntawv txheeb xyuas cuam tshuam. Ntawm lawv, cov ntsiab lus ntawm cov pob slag ua lub luag haujlwm zoo hauv kev siv cov khoom siv fiber ntau, tab sis dab tsi yog cov pob slag?
PART1 Dab tsi yog pob slag
In the process of spinning ceramic fibers into fibers, the vigilant particles that are not fibrillated are called shot. Generally speaking, those with particle size >0.212mm thiab bulk ntom ntawm 2800-3200kg/m3 yuav muab faib ua slag pob.
Judging los ntawm cov txheej txheem tam sim no ceramic fiber ntau lawm, slag pob ntawm cov khoom siv fiber ntau yog inevitable. Ntev npaum li cov ntsiab lus ntawm cov pob slag tsis tshaj tus qauv, cov thermal conductivity ntawm cov khoom siv fiber ntau hauv cov thermal rwb thaiv tsev txheej ntawm cov khoom siv hauv cov khoom siv hluav taws xob twb tau coj los cuam tshuam cov pob slag rau hauv tus account. Yog li ntawd, tsis tas yuav txhawj xeeb ntau dhau ntawm qhov cuam tshuam ntawm cov pob slag ntawm thermal rwb thaiv tsev kev ua haujlwm.
PART2 Slag pob cov ntsiab lus txheem
Lub teb chaws tus txheej txheem teev tseg tias cov ntsiab lus ntawm slag npas nyob rau hauv ceramic fiber pam nrog ib tug kub kuj nyob rau theem qis dua 1000 degree yog tsawg tshaj li los yog sib npaug rau 25 feem pua, cov ntsiab lus ntawm slag npas nyob rau hauv ceramic fiber pam nrog ib tug kub tsis kam. Qib qis dua 1450 degree tsawg dua lossis sib npaug li 20 feem pua, thiab cov ntsiab lus ntawm cov pob slag hauv cov khoom siv fiber ntau hauv qab 1700 degree yog Tsawg dua lossis sib npaug li 5 feem pua, txawv teb chaws tswj cov ntsiab lus ntawm cov pob slag nrog qhov loj me> 0.25mm Tsawg dua los yog sib npaug li 5 feem pua, thaum nyob hauv tsev, vim muaj kev txwv ntawm kev tsim cov tshuab fiber ntau, cov ntsiab lus ntawm cov pob slag raug tswj kom tsawg dua lossis sib npaug li 15 feem pua, uas yog, ze li ntawm 1/8 ntawm cov khoom fiber ntau yog cov pob slag. . Nws yog ob zaug siab dua li ntawm txawv teb chaws. Yog li ntawd, thaum txiav txim siab qhov ntom ntom ntawm cov khoom siv fiber ntau, cov ntsiab lus ntawm cov pob slag yuav tsum tau txiav txim siab tag nrho.
SUNTHERM's ceramic fiber khoom tswj cov ntsiab lus ntawm cov pob slag nrog qhov ntsuas kub ntawm 1450 degree qis dua 7 feem pua los ntawm kev siv tshuab siab heev. Qhov saum npoo yog huv si thiab dawb, thiab cov ntsiab lus ntawm slag pob yog tsawg.
PART3 Kev cuam tshuam ntawm cov ntsiab lus slag ntawm cov khoom siv fiber ntau ceramic
Qhov zoo ntawm cov khoom siv fiber ntau yog txiav txim siab los ntawm cov tshuaj muaj pes tsawg leeg, fiber ntau txoj kab uas hla, fiber ntau ntev, cov ntsiab lus txhaj tshuaj, cua sov xaim shrinkage thiab thermal conductivity, cov ntsiab lus txhaj tshuaj yog qhov tseem ceeb ntawm kev ua tau zoo.
a. Txo cov thermal rwb thaiv tsev kev ua tau zoo ntawm ceramic fiber module;
Cov ntsiab lus siab ntawm slag npas txhais tau hais tias muaj ntau lub lens hais nyob rau hauv ceramic fiber module, uas ua rau lub deterioration ntawm cov qauv ntawm cov paj rwb fiber ntau, qhov loj ntawm cov kab noj hniav, qhov nce ntawm convective tshav kub hloov ntawm huab cua, thiab qhov nce ntawm tag nrho cov thermal conductivity thiab txo qhov thermal rwb thaiv tsev kev ua tau zoo.
b. Txo lub zog ntawm ceramic fiber module;
Lub hav zoov ntawm cov pob slag hloov pauv cov txheej txheem qub ntawm cov paj rwb fiber ntau, ua rau qhov sib txawv ntawm lawv loj dua, txo lub zog ntawm ceramic fiber module, thiab hnav tsis kam thiab hluav taws xob rwb thaiv tsev ntawm cov khoom yuav ua phem dua.
c. Cov nyhuv txuag hluav taws xob tsis zoo, uas ua rau cov neeg siv khoom puas tsuaj;
Cov ntsiab lus ntau dhau ntawm cov pob slag yuav txo qis lub zog txuag kev ua haujlwm ntawm cov khoom siv fiber ntau ceramic, nce kev siv hluav taws xob sab hauv, thiab kev puas tsuaj rau cov neeg siv khoom.
