Kedu ụdị brik silica alumina refractory agụnyere?
Kedu ụdị silica alumina refractory brik gụnyere?
(1) brik silica: na-ezo aka na brik ndị na-emegharị emegharị nwere ihe karịrị 293% SiO, na bụ isi ụdị brik na-emegharị acid. A na-eji ya eme ihe maka iwu ọkụ coke, a na-ejikwa ya maka oghere na akụkụ ndị ọzọ na-ebu ibu nke ọkụ ọkụ maka iko dị iche iche, seramiiki, carbon calciners, na brik na-atụgharị. A na-ejikwa ya na akụkụ dị elu nke na-ebu ibu nke stovu na-ekpo ọkụ, ma a naghị eji ya na ngwa okpomọkụ dị n’okpuru 600 Celsius C yana nnukwu mgbanwe okpomọkụ.
(2) brik ụrọ: brik ụrọ na-abụkarị nke mullite (25%-50%), iko iko (25%-60%), cristobalite na quartz (ruo 30%). A na-ejikarị ụrọ siri ike mee ihe dị ka ihe eji eme ihe, a na-edozi ihe ndị tozuru okè, wee gwakọta ya na ụrọ dị nro, nke a na-emepụta site na ọkara-akọrọ ma ọ bụ plastik, na okpomọkụ bụ 1300 ~ 1400 C iji gbaa ngwaahịa brik ụrọ ọkụ. Ị nwekwara ike ịgbakwunye obere iko mmiri, ciment na ihe ndị ọzọ na-ekekọta iji mee ngwaahịa na-adịghị ọkụ na ihe amorphous. Ọ bụ brik na-ekpugharị nke a na-ejikarị n’ọkụ ọkụ, stovu na-ekpo ọkụ ọkụ, ọkụ ọkụ, ọkụ ọkụ, ọkụ lime, rotary kiln, ceramics na brik na-agbapụ ọkụ.
(3) Brick alumina dị elu: Ngwakọta ịnweta nke brik alumina dị elu bụ corundum, mullite na oge iko. Ọdịnaya ya dabere na nha AL2O3/SiO2 yana ụdị na oke adịghị ọcha. Enwere ike ịkewa brik ndị na-emegharị ahụ dịka ọdịnaya nke AL2O3 si dị. Akụrụngwa ndị a bụ nnukwu alumina bauxite na sillimanite eke eke, yana ndị agwakọta na corundum fused, sintered alumina, sịntetik mullite, na clinker calcined na alumina na ụrọ dị iche iche. A na-emepụta ya nke ukwuu site n’usoro sintering. Mana ngwaahịa ndị a gụnyekwara brik nkedo agwakọtara, brik ọka agwakọtara, brik na-adịghị ọkụ na brik na-enweghị ụdị. A na-eji brik dị elu alumina refractory eme ihe na ụlọ ọrụ nchara, ụlọ ọrụ igwe anaghị agba nchara na ụlọ ọrụ ndị ọzọ.
(4) Brick corundum refractory: brik Corundum na-ezo aka n’ụdị brik na-atụgharị na ọdịnaya nke AL2O3 na-erughị 90% na isi akụkụ nke corundum. Enwere ike kewaa ya ka ọ bụrụ brik corundum sintered na brik corundum jikọtara ya.
