Cenosphere (Microsphere)
Khoom Taw Qhia
Cenosphere yog ib hom ya tshauv hollow pob uas tuaj yeem ntab saum dej.Nws yog greyish dawb, nrog nyias thiab hollow phab ntsa, lub teeb yuag, tej hnyav 250-450kg / m3, thiab particle loj txog 0.1 hli.
Qhov saum npoo yog kaw thiab du, tsis tshua muaj thermal conductivity, hluav taws kub ≥ 1700 ℃, Nws yog ib qho zoo heev thermal rwb thaiv tsev refractory, dav siv nyob rau hauv zus tau tej cov hnyav castable thiab roj drilling.
Lub ntsiab tshuaj muaj pes tsawg leeg yog silica thiab aluminium oxide, nrog cov khoom zoo, hollow, lub teeb yuag, siab zog, hnav tsis kam, kub tsis kam, thermal rwb thaiv tsev, rwb thaiv tsev nplaim hluav taws thiab lwm yam dej num, tam sim no dav siv nyob rau hauv ntau yam lag luam.
