Hom firebricks muaj? Thiab cov yam ntxwv ntawm ntau yam firebricks!
(1) Tsawg creep av nplaum cib, qhov kev ua tau zoo ntawm cov av nplaum hluav taws no yog qhov qis qis, nyob rau hauv qhov kub thiab txias, qhov ntim ruaj khov dua.
(2) phosphoric acid impregnated av nplaum cib, av nplaum cib impregnated los ntawm phosphoric acid tov, alkali slag yaig kuj muaj zog, siab compressive zog.
(3) Tsawg-Porosity Clay Cib, tseem ceeb tshaj plaws ntawm porosity thaum ua, nce ntom ntom pob zeb, kom nws qhov ceev yog qhov zoo, zoo dua lub zog compressive.
(4) Lub teeb ci av nplaum, feem ntau yog siv los ua hluav taws cib rau cov hluav taws kub rwb thaiv tsev ntawm cov kilns, muaj lub teeb ntim, me me ntom ntom, ntau qhov hws thiab zoo rwb thaiv tsev zoo.
