Adkaanta sare ee adkaysiga leh ee Brown Fused Alumina

Bauxite-ka buniga ah ee alumina ee la isku daray sida walxaha ceeriin, dhuxusha, birta, heerkulka sare ee ka sarreeya 2000 darajo ee ku dhaca dhalaalka qaansada, balaastikada shiididda ee warshadda, kala soocidda birlabta ilaa birta, shaashadda waxaa loo qaybiyaa noocyo kala duwan oo cabbir ah, qaab-dhismeed cufan, adkeysi sare, walxaha loo sameeyay globular, isku-darka sare wuxuu ku habboon yahay sameynta dhoobada, xoqidda resin iyo shiididda, nadiifinta, ciidda lagu buufiyo, shubidda, iwm., sidoo kale waxaa loo isticmaali karaa soo saarista kuwa difaacaya horumarsan.

Corundum-ka buniga ah shaqadiisa ugu weyn:
1.Sababtoo ah xooggeeda sare iyo sifooyin kale, waxaa loo isticmaalaa in lagu shubo biraha simbiriirixan, lagu dhalaaliyo biraha naadirka ah, biraha gaarka ah, dhoobada, dahaarka foornada qaraxa (derbiga iyo tuubada); Qalabka jirka iyo kiimikada, qalabka dabka dhaliya, oksaydhka u adkaysta kulaylka - dahaarka u adkaysta.
2.Sababtoo ah astaamaha adkaanta, galmada wanaagsan, xoogga sare, ee nidaamka kiimikada, oo loo isticmaalo noocyo kala duwan oo weelal falcelin ah iyo tuubooyin, qaybaha bamka kiimikada; Samee qaybaha farsamada, dhammaan noocyada caaryada, sida caaryada sawiridda siligga, cadaadi afka caaryada qalinka, iwm.; Samee qalabka, xoqidda caaryada, walxaha aan xabadda karin, kala-goysyada aadanaha, giraanta shaabadaynta iyo wixii la mid ah.
3.Qalabka dahaarka Corundum, sida lebenka iftiinka corundum, kubbadda godka corundum iyo alaabada fiber-ka, oo loo isticmaalo derbiyada foornada heerkulka sare leh iyo dusha sare, labadaba ilaalinta kulaylka. Ciidda cabbirka walxaha Emery waxaa laga sameeyay baloog macmal ah oo emery ah, iyadoo la adeegsanayo duub, shiidid kubbadda, calaamadda barmark iyo qalabka kale, cabbirka walxaha F8-F325. Inta badan waxaa loo isticmaalaa nadiifinta, shiididda, shiididda warshadaha, iwm., sidoo kale waa la dhaqi karaa iyadoo loo eegayo shuruudaha macaamiisha, shiididda iyo habaynta kale, si loo daboolo baahiyaha kala duwan ee macaamiisha.

Korundum bunni ah oo kaarboon yar leh ka dib foornada iyo hab gaar ah oo dib-u-habayn ah, yaree kaarboonka haraaga ah ee ku jira korundum bunni ah, si badeecada la isticmaalayo aan loo burburin, aan loo qarxin, adkaysigu waa warshadaha xoqidda, warshadaha ceeriin ee aan la adkeyn karin. Inta badan waxaa loo isticmaalaa abrades dhoobada ah, abrades, abrades dabiici ah, suumanka, abrades dahaarka leh, iwm., iyadoo loo eegayo kaarboonka haraaga ah waxaa loo qaybiyaa: corundum bunni ah oo calcined C ≤0.05%, corundum bunni ah oo kaarboon yar C ≤0.10%, corundum bunni caadi ah C ≤0.15%.
