Isingeniso, inqubo yokusetshenziswa kanye nokukhiqiza i-corundum emhlophe
I-Alumina Ehlanganisiwe Emhlophe (i-WFA)iyisithambisi sokwenziwa esenziwe ngempuphu ye-alumina yezimboni njengezinto eziyinhloko zokusetshenziswa, ezipholiswa futhi zicwebezeliswe ngemva kokuncibilika kwe-arc yokushisa okuphezulu. Ingxenye yayo eyinhloko yi-aluminium oxide (Al₂O₃), enokuhlanzeka okungaphezu kuka-99%. Imhlophe, iqinile, iqinile, futhi inokumelana okuhle kakhulu nokushisa okuphezulu, ukumelana nokugqwala kanye nezakhiwo zokuvikela. Ingenye yezithambisi ezisetshenziswa kakhulu.
1. Isingeniso Somkhiqizo
I-corundum emhlophe uhlobo lwe-corundum yokwenziwa. Uma iqhathaniswa ne-corundum ensundu, inokuqukethwe okuphansi kokungcola, ubulukhuni obuphezulu, umbala omhlophe, ayinayo i-silica yamahhala, futhi ayinangozi emzimbeni womuntu. Ifaneleka kakhulu ngezikhathi zenqubo ezinezidingo eziphezulu zokuhlanzeka okubukhali, umbala kanye nokusebenza kokugaya. I-corundum emhlophe inobulukhuni be-Mohs obufika ku-9.0, obulandela idayimane ne-silicon carbide kuphela. Inezakhiwo ezinhle zokuzilola, akulula ukunamathela endaweni yokusebenza ngesikhathi sokugaya, futhi inokushisa okusheshayo. Ifanele kokubili izindlela zokucubungula ezomile nezimanzi.
2. Izicelo Eziyinhloko
Ngenxa yezakhiwo zayo eziyingqayizivele zomzimba nezamakhemikhali, i-corundum emhlophe isetshenziswa kabanzi emikhakheni eminingi ephezulu, kufaka phakathi kodwa kungagcini kulezi zici ezilandelayo:
Amathuluzi okugaya kanye nokugaya
Isetshenziselwa ukukhiqiza amasondo okugaya e-ceramic, amasondo okugaya e-resin, indwangu ye-emery, i-sandpaper, ama-scouring pads, ama-grinding pastes, njll. Iyinto yokugaya efanelekile yensimbi enekhabhoni ephezulu, insimbi ye-alloy, insimbi engagqwali, ingilazi, izinto zobumba nezinye izinto.
Ukuqhumisa isihlabathi nokupholisha
Ifanele ukuhlanza ubuso bensimbi, ukususa ukugqwala, ukuqinisa ubuso kanye nokwelashwa okungabonakali. Ngenxa yokuqina kwayo okuphezulu kanye nokungabi nobuthi futhi okungenangozi, ivame ukusetshenziselwa ukubhula ngesihlabathi kanye nokupholisha isikhunta esinembile kanye nemikhiqizo yensimbi engagqwali.
Izinto ezivuselelayo
Ingasetshenziswa njengempuphu ehlanganisiwe noma ecolekile yezitini ezisezingeni eliphezulu eziphikisayo, izinto eziphonswayo, nezinto zokubumba. Isetshenziswa kabanzi ezindaweni ezishisa kakhulu njengensimbi, izinki ze-oven ezincibilikisa insimbi ezingenayo i-ferrous, izinki zeglasi, njll.
Imboni ye-elekthronikhi/yokukhanya
Isetshenziselwa ukukhiqiza izinto zobumba ezihlanzekile kakhulu, ukugaya ingilazi ebonakalayo, ukupholisha i-LED sapphire substrate, ukuhlanza nokugaya i-silicon wafer ye-semiconductor, njll., kanye ne-high-purity ultrafine white corundum powder kuyadingeka.
Ukugcwalisa okusebenzayo
Kusetshenziswa enjolobeni, epulasitikini, embozweni, e-ceramic glaze nakwezinye izimboni ukuthuthukisa ukumelana nokuguguleka, ukuzinza kokushisa kanye nokusebenza kokushisa kwezinto.
3. Inqubo yokukhiqiza
Inqubo yokukhiqiza i-white corundum inzima futhi isayensi, ikakhulukazi ifaka phakathi izinyathelo ezilandelayo ezibalulekile:
Ukulungiswa kwezinto ezingavuthiwe
Khetha i-alumina powder yezimboni ehlanzekile kakhulu (Al₂O₃≥99%), hlola bese uhlola ngamakhemikhali izinto zokusetshenziswa ukuqinisekisa ukuthi okuqukethwe kokungcola kuphansi kakhulu nokuthi usayizi wezinhlayiya uyafana.
Ukuncibilika kwe-arc
Faka i-alumina powder esithandweni se-arc esinezigaba ezintathu bese uyincibilikisa ekushiseni okuphezulu okungaba ngu-2000℃. Ngesikhathi senqubo yokuncibilikisa, ama-electrode ayashiswa ukuze ancibilikise ngokuphelele i-alumina futhi asuse ukungcola ukuze kwakheke i-corundum melt emsulwa.
Ukupholisa i-crystallization
Ngemva kokuba ukuncibilika sekupholile, ngokwemvelo kuyaqina ukuze kwakheke amakristalu amhlophe e-corundum aqinile. Ukupholisa kancane kusiza ukuthuthukiswa kokusanhlamvu nokusebenza okuzinzile, okuyisixhumanisi esibalulekile sokuqinisekisa ikhwalithi ye-corundum emhlophe.
Ukuchoboza kanye nokuhlukaniswa kwamagnetic
Amakristalu e-corundum apholile ayachotshozwa futhi achotshozwe kahle ngemishini yemishini, bese ukungcola okufana nensimbi kususwa ngokuhlukaniswa okunamandla kwamagnetic ukuqinisekisa ubumsulwa bomkhiqizo oqediwe.
Ukuchoboza nokuhlola
Sebenzisa izigayo zebhola, izigayo zokugeleza komoya kanye neminye imishini ukuze uchoboze i-corundum emhlophe ibe usayizi wezinhlayiya ezidingekayo, bese usebenzisa imishini yokuhlola enembile kakhulu ukuze ulinganise usayizi wezinhlayiya ngokwezindinganiso zomhlaba wonke (njenge-FEPA, i-JIS) ukuze uthole isihlabathi noma i-micro powder enezincazelo ezahlukene.
Ukuhlunga kahle kanye nokuhlanza (kuye ngokuthi kuhloswe ngani)
Kwezinye izinhlelo zokusebenza ezisezingeni eliphezulu, njengempuphu ye-corundum emhlophe yebanga le-elekthronikhi kanye ne-optical grade, ukuhlukaniswa kokugeleza komoya, ukucola kanye nokuhlanzwa kwe-ultrasonic kuyenziwa ukuze kuthuthukiswe ukuhlanzeka kanye nokunemba kokulawula usayizi wezinhlayiya.
Ukuhlolwa kwekhwalithi kanye nokupakishwa
Umkhiqizo oqediwe udinga ukudlula ochungechungeni lwezinqubo zokulawula ikhwalithi njengokuhlaziywa kwamakhemikhali (Al₂O₃, Fe₂O₃, Na₂O, njll.), ukutholwa kosayizi wezinhlayiya, ukutholwa kobumhlophe, njll., futhi ngemva kokudlula ukuhlolwa, upakishwa ngokwezidingo zamakhasimende, ngokuvamile ezikhwameni ezingama-25kg noma ezikhwameni zamathani.
Njengezinto zezimboni ezisebenza kahle kakhulu, i-corundum emhlophe idlala indima engenakuphindwa emikhakheni eminingi. Akuyona nje into ebalulekile yokubhula okuphezulu, kodwa futhi iyinto ebalulekile eyisisekelo emikhakheni yobuchwepheshe obuphezulu njengomshini wokulungisa ngokunemba, izinto zobumba ezisebenzayo, nezinto ze-elekthronikhi. Ngokuthuthuka okuqhubekayo kobuchwepheshe bezimboni, izidingo zekhwalithi yemakethe ye-corundum emhlophe nazo ziyathuthuka njalo, okuphinde kukhuthaze abakhiqizi ukuthi baqhubeke nokwenza ngcono izinqubo, bathuthukise ukusebenza komkhiqizo, futhi bathuthuke ngendlela yobumsulwa obuphezulu, usayizi wezinhlayiya ezincane, kanye nekhwalithi ezinzile.
