Adkaynta ugu Fiican ee Miraha Brown ee Aluminium Fused, Ku habboon Abrasives iyo Refractorie

Aluminium oxide brown
BFA
Corundum Brown

Sharaxaad Gaaban

Brown Fused Alumina waxa soo saara dhalaalinta Calcined Bauxite oo ku jirta foorno koronto ah oo heerkul ka weyn 2000°C. Nidaam adag oo tartiib tartiib ah ayaa raacaya isku-dhafka, si ay u soo saaraan crystals blocky. Kaarboonku wuxuu ka caawiyaa ka saarida haraaga baaruudda iyo kaarboonka, Xakamaynta adag ee heerarka Titania inta lagu jiro habka fiyuuska waxay hubisaa adkaanta ugu fiican ee badarka.

Dabadeed cayriin la qaboojiyey ayaa la sii jajabiyaa, laga nadiifiyaa wasakhda birlabeedka ee xoogga sare ee kala-soocida magnetka waxaana loo kala saaraa jajabyo cabbir cidhiidhi ah si ay ugu habboonaato isticmaalka dhammaadka. Khadadka go'an waxay soo saaraan alaabooyin loogu talagalay codsiyada kala duwan.

Codsiga

Brown Fused Alumina waa alumina adag, fiiqan oo fiiqan kaas oo aad ugu habboon in lagu shiido biraha xoogga cufan ee sarreeya. Qalabka kulaylka ayaa ka dhigaya wax aad u fiican oo loo isticmaalo soo saarista alaabada refractory. Qalabkan waxa kale oo loo isticmaalaa codsiyada kale sida qarxinta iyo adkaynta dusha sare.

Fasalka BFA-Brick/ Vitrified: Waxaa lagu soo saaray iyadoo la adeegsanayo heerka Bauxite ee gaarka ah ee cabbirrada fiyuuska la kantaroolay. Darajadani waxa ay ku haboon tahay bulukeeti/alaabooyin kala duwan oo ka hortagaya dildilaacyada/fisyada, godadka iyo dhibco madow ee alaabta dhamaadka.
