Alkali pov thawj castable muaj siab liquidity thiab yog haum rau unshaped refractory ntaub ntawv ua nrog pouring hom. Alkali pov thawj refractory castable muaj ntau yam ntxwv ntawm qhov kub thiab txias tsis kam, siab mechanical zog thiab muaj zog acid yaig tsis kam rau txhua yam ntawm qhov cub thiab daim ntawv thov kilns. Alkali pov thawj castable tuaj yeem hnov mob nrog cov hlau oxide ntawm qhov kub thiab txias ua rau cov khoom siv viscosity siab, uas tsim cov txheej glaze kom tsis txhob nkag mus thiab yaig ntawm alkali melting hlau.
Alkali pov thawj refractory castable yog ua los ntawm refractory aggregates, binders thiab alkali tsis kam hmoov. Nws cov aggregates yog ceramsite, nplaum av clinker, khib nyiab porcelain khoom, siab zog nthuav perlite, thiab lwm yam nrog calcium aluminate cement thiab sodium silicate li binders.
Raws li cov xwm txheej sib txawv thiab ib puag ncig, alkali pov thawj castable tuaj yeem muab faib ua lub teeb alkali pov thawj castable thiab hnyav alkali pov thawj castable. Cov uas muaj porosity ntau dua 45% yog lub teeb alkali pov thawj castable thiab cov porosity tsawg dua 45% yog hnyav alkali pov thawj castable. Qhov hnyav zoo alkali pov thawj castable tuaj yeem muab faib ua nruab nrab kub alkali pov thawj castable thiab kub alkali pov thawj castable.
