Isi mmalite nke brik ụrọ refractory

Brick ụrọ na-ezo aka na ngwaahịa ụrọ nwere ọdịnaya Al2O3 nke 30% -40% aluminum silicate. A na-eji ụrọ ụrọ 50% mee brik ụrọ na 50% ụrọ clinker siri ike, nke a na-agbakọ dịka ihe ụfọdụ chọrọ. Mgbe ịkpụzi na ihicha, ha na-chụọ n’ọrụ na a elu okpomọkụ nke 1300 ~ 1400 ℃. Ngwakọta ịnweta nke brik ụrọ bụ kaolinite (Al2O3 · 2SiO2 · 2H2O) na 6% ~ 7% adịghị ọcha (oxides nke potassium, sodium, calcium, titanium, na ígwè). Usoro ịgba egbe nke brik ụrọ bụ usoro nke mmiri na-aga n’ihu na-aga n’ihu na nbibi nke kaolin iji mepụta kristal mullite (3Al2O3 · 2SiO2). SiO2 na Al2O3 na brik ụrọ na-etolite eutectic silicate dị ala na-agbaze na adịghị ọcha n’oge usoro ịgba egbe, nke gbara kristal kristal gburugburu.

Brick ụrọ bụ ngwaahịa na-eme ka acid na-adịghị ike, nke nwere ike iguzogide mbibi nke slag acid na gas acid, ma nwee ntakịrị ike ọgwụgwụ na ihe ndị alkaline. Brick ụrọ nwere ezigbo ihe na-ekpo ọkụ ma na-eguzogide oyi ngwa ngwa na okpomọkụ ngwa ngwa.
