Amasimu okusetshenziswa kanye nezinzuzo zesihlabathi esinsundu se-corundum
Isihlabathi se-corundum esinsundu, eyaziwa nangokuthi i-brown corundum nomai-corundum ensundu ehlanganisiwe, uhlobo lokuhudula okwenziwe okwenziwe nge-bauxite esezingeni eliphezulu njengezinto eziyinhloko zokusetshenziswa, ezincibilikisiwe futhi zapholiswa ekushiseni okuphezulu okungaphezu kuka-2000℃ esithandweni sikagesi se-arc. Ingxenye eyinhloko yi-aluminium oxide (Al₂O₃), futhi okuqukethwe ngokuvamile kungaphezu kuka-95%. Ngenxa yobulukhuni bayo obuphezulu, ukuqina okuhle, ukumelana nokuguguleka okunamandla kanye nokumelana okuhle kakhulu nokushisa okuphezulu, isetshenziswa kabanzi emikhakheni eminingi yezimboni. Ngokuthuthuka okuqhubekayo kwezidingo zokunemba kokucubungula izinto, ukusetshenziswa kwesihlabathi se-corundum esinsundu ezintweni ezihudulayo, izinto eziphikisayo, ukwelashwa kwendawo, ukwenziwa kwe-casting kanye nezinto ezigcwalisayo ezisebenzayo kuya ngokuya kuba kubaluleke kakhulu.
1. Ukusetshenziswa okubanzi kuma-abrasives
Ama-abrasives angenye yezinkambu zokusetshenziswa zendabuko nezibalulekile ze-corundum ensundu. Ngenxa yobunzima bayo be-Mohs obufika ku-9.0, obulandela idayimane ne-silicon carbide kuphela, i-corundum ensundu isetshenziswa kabanzi ekukhiqizweni kwemikhiqizo ehlukahlukene yokuhuzuka, njengamasondo okugaya, indwangu ye-emery, iphepha lesihlabathi, amatshe kawoyela kanye namakhanda okugaya. Kungakhathaliseki ukuthi kusetshenzwa ngensimbi, ukupholisha ingilazi noma ukugaya nge-ceramic, i-corundum ensundu inganikeza amandla okusika asebenzayo kanye nokumelana okuhle nokuguguleka. Ikakhulukazi ezimweni zezimboni ezidinga ukusika okuqinile nokugcinwa kwesimo okuzinzile, ama-abrasives e-corundum ensundu asebenza kahle kakhulu.
2. Njengezinto zokusetshenziswa ezibalulekile zezinto eziphikisayo
I-corundum ensundu inokushisa okuphezulu kakhulu okuphikisayo kanye nokuqina okuhle kakhulu kokushisa, ngakho-ke isetshenziswa kabanzi ukukhiqiza imikhiqizo ehlukahlukene yokuphikisa esebenza kahle kakhulu.izitofu zezimboni ezishisa kakhulunjenge-metallurgy, insimbi, usimende, kanye nengilazi, i-corundum ensundu ingasetshenziswa ukukhiqiza izitini eziphikisayo zezinga eliphezulu, izinto eziphothwayo, amapulasitiki, izinto zokumisa kanye neminye imikhiqizo ephikisayo, ikakhulukazi ezingxenyeni ezinokuguguleka okukhulu kwezinga lokushisa eliphezulu kanye nokushaqeka okuvamile kokushisa. Uma kuqhathaniswa nezinto zendabuko ze-aluminium ephezulu, izinto eziphikisayo ze-corundum ensundu zinokuguguleka okungcono kwe-slag kanye nokumelana nokuqhekeka, okwandisa ngempumelelo impilo yenkonzo yemishini futhi kunciphisa izindleko zokugcinwa kwebhizinisi.
3. Isicelo kuukuqhuma kwesihlabathikanye nokwelashwa kwendawo
Isihlabathi se-corundum esinsundu sisetshenziswa kabanzi ekuqhumiseni isihlabathi sensimbi ngenxa yobukhulu baso obufanayo bezinhlayiya, ubulukhuni obuphezulu kanye nobukhulu obuthile obuphezulu. Ngesikhathi senqubo yokuqhumisa isihlabathi, i-corundum ensundu ingasusa ngempumelelo ukugqwala, isikali, ungqimba lopende oludala, njll. ebusweni bento yokusebenza, futhi ithuthukise ukuhlanzeka kobuso kanye nokunamathela. Ngesikhathi esifanayo, ngenxa yokuzilola kwayo okuhle futhi akulula ukuyithulisa, ingaphinde isetshenziswe futhi isetshenziswe izikhathi eziningi, okunciphisa kakhulu izindleko zezinto. Ngaphezu kwalokho, i-corundum ensundu iphinde ibonise imiphumela ehlukile ekwelashweni kwe-matte kanye nokucubungula ukuthungwa kobuso kwezinto ezifana nensimbi engagqwali, amaphrofayili e-aluminium, ingilazi, kanye ne-ceramics.
4. Ukusetshenziswa ekubunjweni ngokunemba
Eminyakeni yamuva nje, ngentuthuko eqhubekayo yobuchwepheshe bokuphonsa ngokunemba, kuye kwabekwa phambili izidingo eziphakeme zokuhlanzeka nokuzinza kokushisa kwezinto zokuphonsa.I-corundum ensundu isibe yinto efanelekile yegobolondo yokwenza izinto ngokunemba njenge-alloys yokushisa okuphezulu, insimbi engagqwali, kanye ne-carbon steel ngenxa yokwakheka kwayo kwamakhemikhali okuzinzile, ukuqhuba kahle kokushisa, kanye ne-coefficient yokukhulisa ukushisa ephansi. Isihlabathi sokugaya i-corundum esinsundu singathuthukisa ngempumelelo ikhwalithi yobuso bezinto ezisetshenziswayo futhi sinciphise amaphutha okukhiqiza. Sisetshenziswa kabanzi emikhakheni yokukhiqiza ephezulu njengezindiza, izimoto, kanye namandla.
5. Ukusetshenziswa okwengeziwe njengokugcwalisa okusebenzayo
I-corundum ensundu ingasetshenziswa futhi njengenhlanganisela esebenzayo emikhiqizweni efana nezitezi ezingasheleli, izindawo zokupaka ezingagugi, izimbotshana ze-resin, nezinto zokwakha ezisezingeni eliphezulu. Ubulukhuni bayo obuhle kakhulu kanye nokumelana nokucindezela kusiza ekuthuthukiseni ukumelana nokuguguleka kanye nokuphila kwesikhathi senkonzo yezinto ezihlanganisiwe. Emikhakheni ye-elekthronikhi, izinto zobumba, irabha, njll., i-micropowder ye-corundum ensundu ivame ukusetshenziswa njengesigcwalisi ukuthuthukisa ukumelana nokushisa, ukuqhuba ukushisa, kanye namandla esakhiwo somkhiqizo.
Isiphetho
Isihlabathi se-corundum esinsundu sidlala indima ebalulekile embonini yanamuhla ngezakhiwo zaso ezinhle kakhulu zomzimba kanye nokuqina kwamakhemikhali. Ngokuthuthuka kobuchwepheshe bezinto ezibonakalayo kanye nezidingo zokucubungula izimboni, amathuba emakethe esihlabathi se-corundum esinsundu azoba maningi futhi azoletha nezixazululo ezisebenzayo nezinobungani nemvelo ezimbonini eziningi.
