Kedu ihe bụ usoro ịgba egbe nke brik refractory?
Gịnị bụ igba egbe nke brik na -agbanwe agbanwe?
The igba egbe nke refractory brik bụ tumadi usoro nke akpịrị ịkpọ nkụ na-aga n’ihu na decomposition nke kaolin iji mepụta kristal mullite (3Al2O3 · 2SiO2). SiO2 na Al2O3 na brik refractory na-etolite silicate dị ala na-agbaze eutectic na adịghị ọcha n’oge usoro ịgba egbe, nke gbara kristal mullite gburugburu. A na-achịkwa okpomọkụ kachasị elu n’oge usoro ịgba ọkụ na 1350 ° C ruo 1380 ° C. Ọ bụrụ na ọkụ ọkụ nke brik ụrọ dị ala na-abawanye nke ọma (1420 Celsius C), nkwụsị nke brik ndị na-atụgharị ga-abawanye ntakịrị, nke mere na njupụta nke brik ndị na-atụgharị ga-abawanye ntakịrị, na obere porosity nwere ike nweta. belata.
