Indima Entsha ye-White Corundum ekuGuqukeleni Kwezobuchwepheshe Bezokwelapha
Manje, ngeke iqhekeke ngisho noma iwiswe—imfihlo ikule ngubo ‘yesafire emhlophe’.” “Isafire emhlophe” ayekhuluma ngayo kwakuyii-corundum emhlopheisetshenziswa ekupholisheni insimbi yezimboni. Lapho le kristalu ye-aluminium oxide, enobunzima be-Mohs obungu-9.0 kanye nobumsulwa bamakhemikhali obungu-99%, ingena emkhakheni wezokwelapha, kwaqala inguquko ethule ezintweni zezokwelapha.
1. Kusukela Emasondo Okugaya Ezimbonini Kuya Emajoyintini Abantu: Uguquko Olunqamula Imingcele Kwesayensi Yezinto Eziphathekayo
Ungase uzibuze ukuthi isihluthulelo esasisetshenziswa ekuqaleni ukusika insimbi sesibe kanjani isithandwa esisha emkhakheni wezokwelapha. Kalula nje, ukuphishekela okuyinhloko kobuchwepheshe bezokwelapha “i-biomimeticism”—ukuthola izinto ezingahlangana nomzimba womuntu futhi zikwazi ukumelana namashumi eminyaka okuguga nokudabuka.I-corundum emhlopheNgakolunye uhlangothi, inesakhiwo "esiqinile":
Ubulukhuni bayo buphikisana noboidayimane, futhi ukumelana kwayo nokuguguleka kudlula kathathu kunalokho okwenziwa yizihlanganisi zensimbi zendabuko.
Ukungangeni kwayo kwamakhemikhali kunamandla kakhulu, okusho ukuthi ayiboli, ayigqwali, noma ibangele ukwenqatshwa emzimbeni womuntu.
Ubuso bayo obufana nesibuko benza kube nzima ngamabhaktheriya ukunamathela, okunciphisa ingozi yokutheleleka ngemva kokuhlinzwa.
Kusukela ngo-2018, ithimba lezokwelapha eShanghai laqala ukuhlola ukusetshenziswa kweokumbozwe nge-corundum emhlopheamalunga. Uthisha womdanso owashintshwa ngokuphelele emathangeni wabuyela esiteji ezinyangeni eziyisithupha ngemuva kokuhlinzwa. “Amalunga ami ensimbi ayevame ukungikhathaza kakhulu kangangokuthi isinyathelo ngasinye sasizwakala sengathi siphula ingilazi. Manje, cishe ngiyakhohlwa ukuthi akhona lapho ngidansa.” Njengamanje, isikhathi sokuphila salezii-corundum-ceramic emhlopheIzihlanganisi ezihlanganisiwe sezidlule iminyaka engama-25, cishe kabili kunezezinto zendabuko.
II. “Umqaphi Ongabonakali” Osesicongweni Se-Scalpel
Uhambo lwezokwelapha lwe-White corundum lwaqala ngokuguqulwa kwalo okukhulu kwamathuluzi ezokwelapha. Emsebenzini wokukhiqiza amadivayisi ezokwelapha, uMqondisi Wezobuchwepheshe uLi wakhomba umugqa wezinsimbi zokuhlinzwa ezikhazimulayo wabe esechaza, “Ngemuva kokupholisha amathuluzi ensimbi engagqwali ngei-white corundum micropowder, ukugoba kobuso kuncishiswe kube ngaphansi kwama-micron angu-0.01—okubushelelezi kunobukhulu obuyinkulungwane eziyishumi bonwele lomuntu.” Lo mphetho wokusika obushelelezi ngendlela emangalisayo wenza ukusika ngokuhlinzwa kube bushelelezi njengommese oshisayo ngebhotela, kunciphisa ukulimala kwezicubu ngo-30% futhi kusheshise kakhulu ukuphulukiswa kwesiguli.
Ukusetshenziswa okuguquguqukayo nakakhulu kusekuguleni amazinyo. Ngokwesiko, uma kusetshenziswa ama-burs abrasive edayimane ekugayeni amazinyo, ukushisa okubangelwa ukungqubuzana okuvama kakhulu kungalimaza i-pulp yamazinyo. Kodwa-ke, isici sokuzilola salokhui-corundum emhlophe(ukuthuthukisa njalo imiphetho emisha ngesikhathi sokusetshenziswa) kuqinisekisa ukuthi i-bur ihlala ibukhali njalo. Imininingwane yezokwelapha evela esibhedlela samazinyo saseBeijing ikhombisa ukuthi ngesikhathi sokwelashwa kwezimpande kusetshenziswa ama-white corundum burs, izinga lokushisa le-dental pulp likhuphuka ngo-2°C kuphela, ngaphansi kakhulu komkhawulo wokuphepha wamazwe ngamazwe ongu-5.5°C.
III. Ukufakwa Kwezimbozo: Ukunikeza Izitho Zokwenziwa “Isivikelo Sedayimane”
Ukusetshenziswa kwezokwelapha okucatshangwa kakhulu kwe-corundum emhlophe yikhono layo lokunikeza izitho zokwenziwa "impilo yesibili." Kusetshenziswa ubuchwepheshe bokufafaza nge-plasma, i-corundum micropowder emhlophe ifafazwa ngokuncibilika ebusweni be-titanium alloy joint ekushiseni okuphezulu, yakha ungqimba oluqinile lokuvikela olunobukhulu obuyi-10-20 microns. Ubuhlakani balesi sakhiwo bulele ku:
Ingqimba yangaphandle eqinile imelana nokungqubuzana kwansuku zonke.
Isisekelo sangaphakathi esiqinile sibamba imithelela engalindelekile.
Isakhiwo esinezimbobo ezincane sikhuthaza ukukhula kwamangqamuzana amathambo azungezile.
Ukulingisa elabhorethri yaseJalimane kubonise ukuthi ngemva kwemijikelezo yokuhamba eyizigidi ezi-5, ukuguguleka kwe-prosthesis yamadolo embozwe nge-corundum emhlophe kwakuyi-1/8 kuphela ye-titanium emsulwa. Izwe lami lifake lobu buchwepheshe ohlelweni lwayo lwe-"Green Channel for Innovative Medical Devices" kusukela ngo-2024. Amalunga e-hip amhlophe akhiqizwe ngaphakathi ashibhile ngo-40% kunemikhiqizo engenisiwe, okuzuzisa amakhulu ezinkulungwane zeziguli ezinezifo zamathambo.
IV. I-White Corundum “High-Tech” eKliniki Yesikhathi Esizayo
Ezokwelapha Phakathi kwenguquko yezobuchwepheshe, i-white corundum ivula imingcele emisha:
Isikali se-Nanoukupholisha kwe-corundum emhlophe Ama-ejenti asetshenziswa ekwenziweni kwama-chip okulandelana kwezakhi zofuzo, okwandisa ukunemba kokutholwa kusuka ku-99% kuya ku-99.99%, okwenza kube lula ukuhlolwa komdlavuza kusenesikhathi.
Ithambo lomgogodla eliprintiwe nge-3D elinohlaka oluqiniswe yi-corundum elimhlophe linikeza amandla okucindezela aphindwe kabili kunamathambo emvelo, okunikeza ithemba kubantu abanesimila somgogodla.
Izembozo ze-biosensor zisebenzisa izakhiwo zokuvikela ze-corundum emhlophe ukuze kufezwe ukudluliselwa kwezimpawu zokuxhumana kobuchopho nekhompyutha ngaphandle kokuphazamiseka.
Ithimba locwaningo laseShanghai lize lakha nezikulufo zamathambo ezimhlophe ze-corundum ezibolayo—eziqala ngokusekela okuqinile futhi zikhulule kancane kancane ama-ion e-aluminium akhuthaza ukukhula njengoba ithambo liphola. “Esikhathini esizayo, ukuhlinzwa kokuphuka kungase kuqede isidingo sokuhlinzwa kwesibili ukuze kususwe isikulufo,” kusho uDkt. Wang, umholi wephrojekthi, ngenkathi ethula idatha yokuhlola evela kuma-rabbit tibias: ngemva kwamasonto ayisishiyagalombili, ivolumu yesikulufo yehle ngo-60%, kuyilapho ubuningi bethambo elisanda kwakheka babuphindwe kabili kunobeqembu lokulawula.
