Ihe gbasara Bricks Mullite
Brick dị iche iche bụ ihe nkwụghachi azụ aluminom dị elu yana mullite dị ka akụkụ kristal bụ isi.N'ozuzu, ọdịnaya nke alumina dị n'etiti 65% na 75%.Na mgbakwunye na mullite, mineral ndị nwere alumina dị ala nwekwara obere akụkụ nke vitreous na cristobalite.Ọdịnaya alumina dị elu nwekwara obere corundum.
Brick dị iche iche nwere nnukwu refractoriness, nke nwere ike iru n'elu 1790 Celsius.Ibu ibu nro mmalite okpomọkụ bụ 1600 ℃ 1700 ℃.Ike mkpakọ na ụlọ okpomọkụ bụ 70-260MPa.Ezigbo nguzogide ujo thermal.
Enwere ụdị brik mullite abụọ gbakọtara na brik mullite jikọtara ọnụ.
A na-eji brik mullite dị elu mee ihe dị elu nke alumina bauxite clinker dị ka isi ihe eji eme ihe, na-agbakwunye obere ụrọ ma ọ bụ raw bauxite dị ka ihe nkedo, na-etolite ma gbaa ya ọkụ.A na-eji blọk mullite fused nke bauxite dị elu, alumina mmepụta ihe na ụrọ refractory, na unyi ma ọ bụ coke dị mma na-agbakwunye dị ka onye na-ebelata ihe.Mgbe akpụzichara, a na-emepụta ha site na ibelata electrofusion.
Ntucha nke mullite fused buru ibu karịa nke sintered mullite, na nguzogide okpomọkụ ya dị mma karịa nke ngwaahịa ndị na-esighị ike.Ọrụ okpomọkụ ha dị elu na-adabere na ọdịnaya nke alumina na ịdị n'otu nke nkesa nke oge mulite na iko.
A na-eji brik dị iche iche eme ihe maka stovu na-ekpo ọkụ na-ekpo ọkụ, ahụ ọkụ na-agbawa ọkụ na ala, igwe ọkụ ọkụ ọkụ, ceramic kiln, mkpuchi nkuku nwụrụ anwụ nke sistemu mgbawa mmanụ, wdg.
Banyere Sillimanite
Brick sillimanite nwere ezigbo nkwụsi ike na okpomọkụ dị elu, iguzogide mmiri mmiri mmiri mmiri, obere mmetọ na mmiri mmiri iko.
Ọtụtụ dabara adaba maka ọwa nri, igwe nri, igwe na-adọkpụ tube na akụrụngwa ndị ọzọ na ụlọ ọrụ iko, nke nwere ike melite nrụpụta.
