Xa abantu besiva igama elithi White Fused Alumina Micropowder, abaninzi abangaphandle kweshishini lokurhawuzelela banokulifumanisa lingaqhelekanga. Sekunjalo le powder emhlophe icocekile ibandakanyeka ngokuzolileyo kwiinkalo ezininzi zobomi bemihla ngemihla—ukusuka kwizikrini zefowuni kunye neelensi zeglasi ukuya kwizinto zeemoto kunye neendawo zeenqwelo moya. Njenge-abrasive yokwenziwa ecocekileyo kakhulu, eqinileyo kakhulu, i-alumina micropowder emhlophe edibeneyo ixatyiswa ngenkqubo yayo yokuvelisa echanekileyo kunye noluhlu olubanzi lwezicelo zoshishino.
Ukusuka kwiMpahla eluhlaza ukuya kwiMicropowder: Inkqubo yoMveliso eNgqongileyo
Abaninzi bacinga ukuba i-micropowder yenziwa ngokutyumza iinkozo ezinkulu ezimhlophe ze-alumina ezixutyiweyo, kodwa inyani inzima kakhulu.
1. Ukukhethwa kwezinto eziluhlaza kunye nonyango lwangaphambi kwexesha
Umgubo we-alumina omhlophe oxutywe kakuhle okumgangatho ophezulu uqala ngomgubo we-alumina we-industrial ophambili, onobunyulu be-Al₂O₃ obungaphezulu kwe-99.5%. Izinto ezicocekileyo eziphantsi zinokuchaphazela ubulukhuni, ubumhlophe, kunye nokuzinza kweekhemikhali. Ngaphambi kokunyibilikisa, umgubo oluhlaza uyahluzwa kwaye uhlelwe ngomoya ukuze kususwe amasuntswana arhabaxa kwaye kuqinisekiswe ubungakanani obufanayo bamasuntswana ukuze kunyibilike kakuhle.
2. Ukunyibilika kunye nokuKristalwa kwesithando somlilo se-Arc yoMbane
Umgubo we-alumina ocociweyo kwangaphambili uyanyibilikiswa kwisithando sombane esinezigaba ezintathu kumaqondo obushushu angama-2050–2150°C kangangeeyure ezi-4–6. Kobu bushushu bugqithisileyo, i-alumina iyanyibilika ngokupheleleyo ibe lulwelo, ngelixa ukungcola kuyahlukana kwaye kuhlala ngenxa yokwahluka koxinano.
Ulawulo lobushushu lubaluleke kakhulu ngeli nqanaba. Ii-electrode zifakwa nzulu echibini elinyibilikisiweyo ukuqinisekisa ukufudumeza okufanayo. Ngexesha lokuphola, kufakwa ukupholisa ngokukhawuleza kumaqondo obushushu aphezulu, kulandele ukupholisa okucothayo kumaqondo obushushu aphantsi, okuvumela iikristale ze-α-Al₂O₃ ezizinzileyo ukuba zenzeke. Nje ukuba zipholile, izinto ziyaqina zibe ngamaqhuma e-alumina axineneyo, amhlophe adityanisiweyo anobunzima obubalaseleyo kunye nokuqina.
3. Ukutyumza, ukuGcoba, kunye nokuHlela ngokuchanekileyo
Iibhloko ze-alumina ezidityanisiweyo ziqala zityunyuzwe zizitshizi zemihlathi, emva koko zincitshiswe kakuhle zii-roller mills, kwaye ekugqibeleni zicutshungulwe zibe ngumgubo we-micron kusetyenziswa ii-jet mills.
Ukuze kufezekiswe ukusasazwa kobukhulu beesuntswana ngokuchanekileyo, ukuhlelwa kobuninzi be-hydraulic kunye neenkqubo zokuhlelwa kokuhamba komoya zisetyenziselwa ukwahlula amanqanaba ahlukeneyo afana ne-W5, i-W10, kunye ne-W20, ezinye iimveliso zifikelela kumanqanaba e-submicron.
Emva kokuhlelwa, umgubo uhlanjwa nge-asidi, uhlanjwe ngamanzi, womiswe, kwaye wahlulwe ngemagnethi ukuze kususwe i-iron eseleyo, i-sodium, kunye nezinye izinto ezingcolileyo. Ukuhlolwa kokugqibela komgangatho kubandakanya ukuvavanywa nge-microscopic kunye nohlalutyo lobungakanani bamasuntswana ngaphambi kokupakishwa.
