Kev tsim technology ntawm taphole av nplaum

Kev tsim technology ntawm taphole av nplaum:

Qhov sib xyaw ntawm cov av nplaum uas tsis muaj dej tuaj yeem muab faib ua ob ntu - refractory aggregate thiab binder. Refractory aggregate yog hais txog cov khoom siv refractory xws li corundum, mullite, coke gem thiab hloov cov ntaub ntawv xws li coke thiab mica. Lub binder yog dej los yog tar pitch thiab phenolic resin thiab lwm yam ntaub ntawv organic, tab sis kuj tov nrog SiC, Si3N4, expansion agents thiab admixtures. Sib sau ua ke raws li ib qho me me thiab qhov hnyav ntawm cov matrix, nyob rau hauv kev sib xyaw ntawm cov ntaub ntawv kom nws muaj qee yam plasticity, kom cov av nkos tuaj yeem raug tsav mus rau hauv lub qhov ncauj hlau los thaiv cov hlau kub.
