Pores nyob rau hauv refractories tau muab faib ua peb pawg
1. Kaw qhov, kaw hauv cov khoom thiab tsis txuas nrog lub ntiaj teb sab nrauv
2.Open pore ， ib kawg tau kaw thiab lwm qhov kawg txuas nrog lub ntiaj teb sab nrauv
3.Txhua lub qhov cua thiab ob sab ntawm cov khoom. Qhov porosity ntawm cov khoom siv refractory ntom yog hais txog qhov pom porosity P, uas yog, feem pua ntawm qhib qhov hws thiab los ntawm qhov hws hauv tag nrho cov pore ntim. Pom qhov porosity yog qhov tseem ceeb cuam tshuam rau cov khoom ntawm cov khoom siv hluav taws xob ntom ntom ntawm chav sov thiab kub. Tshwj xeeb tshaj yog nyob rau qhov kub thiab txias, nws yuav txo qis qhov tsis kam ntawm cov khoom mus rau sab nrauv. Qhov laj thawj rau kev tsim cov pores yog: huab cua hauv cov khoom tsis raug tshem tawm tag nrho thaum tsim cov khoom, qhov chaw seem tom qab cov dej noo ntawm cov khoom raug tshem tawm, cov calcination ntawm cov ntaub ntawv tsis txaus, cov khoom uas yuav tsum tau hlawv tsis yog kub hnyiab tag, cov khoom siv sib xyaw ua ke tsis sib xws, qhov ntsws tsis sib xws thaum kub kub, thiab lwm yam
