Ceramic hais yog lub teeb yuag aggregates tsim los ntawm foaming nyob rau hauv teb kilns. Nws muaj ib tug kheej kheej, ib tug du thiab tawv nto, thiab ib tug honeycomb zoo li sab hauv, tus yam ntxwv ntawm tsawg ceev, tsawg thermal conductivity, thiab siab zog. Hauv kev lag luam khoom siv refractory, cov khoom siv ceramic feem ntau yog siv los ua cov khoom sib xyaw rau cov khoom siv thermal rwb thaiv tsev refractory.
Lub stacking ceev ntawm cov khoom ceramic yog tsawg dua 1100kg/m3, feem ntau yog li ntawm 300-900kg/m3. Qhov ntom ntawm cov pob zeb ua nrog cov khoom siv ceramic raws li kev sib sau ua ke yog 1100-1800kg / m3, thiab qhov sib xyaw ua ke ntawm cov pob zeb sib xyaw yog 30.5-40.0Mpa. Cov yam ntxwv ntawm cov khoom siv ceramic yog tias lawv muaj qhov tawv tawv thiab ntau micropores sab hauv. Cov micropores no tso cai rau cov khoom siv ceramic nrog cov yam ntxwv ntawm kev sib sib zog nqus. Qhov ntom ntawm No. 200 ya tshauv ceramic aggregate pob zeb yog li 1600kg / m3. Tam sim no, cov xuab zeb ceramic feem ntau yog siv los ua cov roj av hauv Suav teb thiab tseem yog ib qho ntawm cov kev thov siab ceramic xuab zeb ntau yam, tseem hu ua roj av fracturing proppant ceramic xuab zeb.
Qhov laj thawj yog vim li cas cov khoom siv ceramic tau tsim sai heev thoob ntiaj teb yog vim lawv muaj ntau yam khoom zoo heev uas lwm cov ntaub ntawv tsis muaj, uas ua rau lawv lub luag haujlwm tsis tuaj yeem hloov los ntawm lwm cov ntaub ntawv. Cov kev ua tau zoo tshaj plaws no muaj cov hauv qab no.
1, Thermal rwb thaiv tsev: Cov khoom siv ceramic yog muab los ntawm cov khoom siv ceramic muaj cov thermal rwb thaiv tsev zoo vim lawv cov ntxeem tau sab hauv. Lub thermal conductivity ntawm pob zeb npaj nrog lawv feem ntau yog 0.3-0.8W/(m · k), uas yog 1-2 npaug qis dua li cov pob zeb zoo tib yam. Yog li, cov tuam tsev ceramic muaj qhov chaw zoo thermal.
2, Kev tiv thaiv hluav taws zoo heev: Ordinary ya tshauv ceramic aggregate pob zeb lossis ya tshauv ceramic aggregate blocks ua ke rwb thaiv tsev, av qeeg tsis kam, Frost tsis kam, hluav taws kub thiab lwm yam khoom, tshwj xeeb tshaj yog qhov hluav taws kub tiv taus ntau tshaj plaub npaug ntawm cov pob zeb zoo tib yam. Rau tib lub sijhawm tiv thaiv hluav taws, lub thickness ntawm cov pob zeb ceramic aggregate yog 20% thinner dua li cov pob zeb zoo tib yam. Tsis tas li ntawd, ya tshauv ceramic hais tuaj yeem siv los npaj cov pob zeb refractory nrog hluav taws kub qis dua 1200 degree. Ntawm qhov kub ntawm 650 degree, ceramic aggregate pob zeb tuaj yeem tswj tau 85% ntawm nws lub zog ntawm chav tsev kub. Ordinary pob zeb tsuas tuaj yeem tswj tau 35% mus rau 75% ntawm nws lub zog ntawm chav tsev kub.
