Ego ole ka mullite brik mkpuchi mkpuchi dị mfe nwere ike ịnagide?
Brick mkpuchi mkpuchi Mullite bụ ụdị ihe na -agbanwe agbanwe, nke nwere ike ịkpọtụrụ ọkụ ozugbo. Ọ nwere njirimara nke iguzogide oke okpomọkụ, ịdị elu dị elu, conductivity thermal dị ala, yana mmetụta ịchekwa ike. Bricks mkpuchi mkpuchi dị mfe Mullite nwere njirimara nke arụmọrụ dị elu na ọnụ ala dị ala. Enwere ike iji ha maka ịkwa akwa, nke nwere ike ọ bụghị naanị belata ogo ọkụ ahụ, chekwaa mgbanye ọkụ, kamakwa ịgbatị ndụ ọrụ nke mkpuchi ọkụ ma belata mmezi mmezi.
A na-eji brik, ụrọ, “okwute atọ”, wdg eme brik mkpuchi mkpuchi mullite dị mfe, site na nguzobe nke pores na-ejikọ ma ọ bụ mechiri emechi na ịkpụzi ihe ma ọ bụ usoro ịkpa oke ọkụ.
Atụmatụ nke brik mkpuchi mkpuchi dị mfe:
Ego ole ka mullite brik mkpuchi mkpuchi dị mfe nwere ike ịnagide? Nnukwu nguzogide nke brik mkpuchi mkpuchi mullite nwere ike iru karịa 1790 ℃. Ibu mmalite nro dị nro bụ 1600-1700 ℃, ike mkpakọ ọkụ na-adịkarị bụ 70-260MPa, nguzogide ujo dị mma, ike dị elu, ọnụego mgbago dị elu dị ala, ọnụọgụ mgbasa dị ala, ọnụọgụ ọnụọgụ. dị obere, acid slag na -eguzogide. Ọ nwekwara ike belata ịdị arọ nke ahụ ọkụ na-ekpo oke ọkụ, gbanwee usoro ahụ, chekwaa ihe, chekwaa ike, ma melite arụmọrụ nke ọma.
Ngwa ngwa nke brik mkpuchi mkpuchi dị mfe:
A na-ejikarị brik mkpuchi mkpuchi dị larịị nke Mullite maka nnukwu ọkụ dị elu karịa 1400 ℃, elu ụlọ ọkụ dị elu, isi ala, arche regenerator, nnukwu ihe ọkụ ọkụ na-agbaze iko, seramiiki sintering kilns, seramiiler roller kilns, ọwa mmiri ọkụ, Ihe mkpuchi dị n’ime. Ebe a na -adọba ihe, ebe a na -enwu ọkụ nke ihe na -esi na mmanụ gbawara agbawa, nnukwu ite ọkụ na ite ọkụ eletrik dị iche iche nwere ike ịkpọtụrụ ọkụ ahụ ozugbo.
