Ceramic fiber board yog cov khoom siv refractory uas tswj cov khoom siv zoo tom qab cua sov. Tso nws mus rau hauv lub tank tsim thiab do nrog compressed cua. Muab cov pwm tso rau hauv lub tank tsim, thiab siv lub hauv paus ntsiab lus ntawm lub tshuab nqus tsev rau adsorb fiber ntau slurry ntawm pwm. Nws dabtsi yog khoov tsis kam?
Thaum peb kawm txog cov ceramic fiberboard, peb soj ntsuam cov pob txha micro morphology ntawm cov silica sol plhaub ntxiv tom qab khoov pob txha. Lub sijhawm no, kev txhim kho cov txiaj ntsig ntawm matrix tsis pom tseeb, tsuas yog 0.28 MPa thiab 0.45 MPa, nce li ntawm 12 mus rau 19%. Raws li cov ntsiab lus fiber ntau nce mus rau 0.6% thiab 0.8%, tus naj npawb ntawm cov fibers ntawm qhov tawg ntawm cov ceramic fiberboard maj mam nce thiab sib npaug sib npaug hauv lub plhaub pwm. Qhov no qhia tau hais tias cov fibers tau zoo dispersed thaum lub sij hawm txheej txheej txheej txheej txheej txheej, yog li cov fibers uas koom rau hauv kev ntxiv dag zog rau tus naj npawb tau nce, yog li qhia txog kev txhim kho ntawm tag nrho cov kev txhawb zog.
Lub sijhawm no, txoj kab uas hla shrinkage tuaj yeem pom ntawm cov fibers uas twb muaj lawm ntawm qhov tawg ntawm cov khoom, uas yog tshwm sim los ntawm elastic deformation nyob rau hauv cov txheej txheem ntawm fiber ntau puas thiab debonding. Los ntawm kev nce tus naj npawb ntawm cov fibers, lub plhaub seem tuaj yeem pom los ntawm cov fibers ntawm qhov tawg ntawm cov ceramic fiberboard, uas qhia tau hais tias cov ceramic fiberboard zoo bears lub load thaum lub sij hawm debonding txheej txheem, uas qhia tau hais tias qhov kev soj ntsuam soj ntsuam tau pab txhim kho. khoov kev ua tau zoo ntawm fiberboard.
