Cenosphere (Microsphere)
Kev Taw Qhia Txog Khoom
Cenosphere yog ib hom pob zeb uas muaj cov tshauv ya uas ntab tau saum dej. Nws yog xim dawb greyish, nrog cov phab ntsa nyias thiab khoob, lub teeb, qhov hnyav ntawm cov khoom loj yog 250-450kg / m3, thiab qhov loj ntawm cov khoom me me yog li 0.1 hli.
Qhov saum npoo yog kaw thiab du, tsis tshua muaj thermal conductivity, hluav taws tsis kam ≥ 1700 ℃, Nws yog ib qho zoo heev thermal rwb thaiv tsev refractory, dav siv nyob rau hauv kev tsim cov teeb pom kev zoo castable thiab roj drilling.
Cov tshuaj lom neeg tseem ceeb yog silica thiab txhuas oxide, nrog cov khoom me me, hollow, lub teeb yuag, lub zog siab, hnav tsis kam, kub tsis kam, thermal rwb thaiv tsev, rwb thaiv tsev hluav taws kub retardant thiab lwm yam haujlwm, tam sim no dav siv hauv ntau yam lag luam.
