Ho utloisisa mokhoa oa ho bala oa ho teteana ha refractory castable, lesoba la moea ke eng?
1. Ho na le mefuta e meraro ea li-pores:
1. Lehlakore le leng le koetsoe 'me le leng le buisana le ka ntle, le bitsoang pore e bulehileng.
2. Pore e koetsoeng e koetsoe ka sampuli mme ha e kopane le lefatše le ka ntle.
3. Likoti li bitsoa ka mekoti.
Kakaretso ea porosity, e leng porosity ea 'nete, e bolela peresente ea palo eohle ea li-pores ka kakaretso ea molumo oa sampuli;Ka kakaretso, sekoti se phunyeletsang se kopantsoe le lesoba le bulehileng, 'me sekoti se koetsoeng ha se bonolo ebile se thata ho lekanya ka ho toba.Ka hona, porosity e bontšoa ke porosity e bulehileng, ke hore, e bonahalang eka ke porosity.Porosity e bonahalang e bolela peresente ea palo eohle ea li-pores tse bulehileng ka sampuli ho palo eohle ea sampuli.
Bongata bo boholo bo bolela karo-karolelano ea molumo o ka lahloang oa sampuli e omisitsoeng ho kakaretso ea molumo oa eona, ke hore, karo-karolelano ea molumo oa 'mele oa porous ho ea ho kakaretso ea eona, e hlahisoang ka Kg/m3 kapa g/cm3.The bonahalang porosity le bongata density ke e 'ngoe ea metheo ea ho laola bongata ba refractory castable kaho.Li-index tse peli tsa ts'ebetso li ka lekanyetsoa ka sampole e tšoanang.Lintlha tse latelang ke bongata bo bongata le porosity e hlakileng ea li-castable tse sebelisoang hangata.
2. Tse latelang ke bongata bo bongata le porosity e bonahalang ea li-castable tse sebelisoang ka tloaelo.
