Indima Entsha yeWhite Corundum kwiNguquko yeTekhnoloji yezonyango
Ngoku, ayizukuqhekeka nokuba iwisiwe—imfihlo ikwisigqubuthelo ‘sesafire emhlophe’.” “Isafire emhlophe” awayethetha ngayo yayiyii-corundum emhlopheisetyenziswa ekupolisheni ngentsimbi yemizi-mveliso. Xa le kristale ye-aluminium oxide, enobunzima be-Mohs obuyi-9.0 kunye nobunyulu beekhemikhali obuyi-99%, yangena kwicandelo lezonyango, kwaqala utshintsho oluzolileyo kwizixhobo zonyango.
1. Ukusuka kumavili okuGrila kwiMizi-mveliso ukuya kumajoyinti abantu: uguquko olunqamlezileyo kwiSayensi yezinto eziphathekayo
Usenokuba uzibuza ukuba isikrufu esasisetyenziswa ekuqaleni ukusika isinyithi siye saba yinto entsha ethandwayo kwicandelo lezonyango. Ngamafutshane, eyona nto iphambili kubuchwepheshe bezonyango yi-"biomimeticism" - ukufumana izinto ezinokudibana nomzimba womntu kwaye zikwazi ukumelana nokuguga kwamashumi eminyaka.I-corundum emhlophekwelinye icala, inesakhiwo "esiqinileyo":
Ubulukhuni bayo buphikisana noboidayimani, kwaye ukumelana kwayo nokuguguleka kudlula kathathu kunokwamalungu esinyithi emveli.
Ukungangeni kwayo kwiikhemikhali kunamandla kakhulu, oko kuthetha ukuba ayiboli, ayigqwali, okanye ayibangeli ukwaliwa emzimbeni womntu.
Umphezulu wayo ofana nesipili wenza kube nzima ukuba iintsholongwane zinamathele kuwo, nto leyo enciphisa umngcipheko wokosuleleka emva kotyando.
Kwangowama-2018, iqela lezonyango eShanghai laqala ukuhlola ukusetyenziswa kwei-corundum emhlophe egqunywe nge-corundumamalungu omzimba. Utitshala womdaniso owafakelwa isinqe ngokupheleleyo wabuyela eqongeni emva kweenyanga ezintandathu emva kotyando. “Amalungu am esinyithi ayendidinisa kakhulu kangangokuba inyathelo ngalinye lalivakala ngathi liqhekeza iglasi. Ngoku, ndiphantse ndilibale ukuba akhona xa ndidanisa.” Okwangoku, ubomi bezii-corundum-ceramic emhlopheIijoyinti ezidityanisiweyo zidlule iminyaka engama-25, phantse ziphindwe kabini kunezo zezixhobo zemveli.
II. “Umgcini Ongabonakaliyo” kwiNcam yeScalpel
Uhambo lwezonyango lweWhite corundum luqale ngotshintsho olukhulu lwezixhobo zonyango. Kwiworkshop yokwenza izixhobo zonyango, uMlawuli wezobuGcisa uLi wakhomba uthotho lwee-forceps zotyando ezikhazimlayo waza wachaza, “Emva kokupolisha izixhobo zentsimbi engagqwaliyo ngeumgubo omncinci we-corundum omhlophe, uburhabaxa bomphezulu buncitshiswa bube ngaphantsi kwe-0.01 microns—buthambile kune-10000 leekhilogram ubukhulu beenwele zomntu.” Le ndlela yokusika egudileyo kakhulu yenza ukusika ngotyando kube bushelelezi njengemela eshushu ngokusebenzisa ibhotolo, kunciphisa umonakalo wezicubu ngama-30% kwaye kukhawulezise kakhulu ukuphiliswa kwesigulana.
Enye indlela entsha ngakumbi kunyango lwamazinyo. Ngokwesiko, xa kusetyenziswa izinyo ezirhabaxa zedayimani xa kusiliwa amazinyo, ubushushu obuveliswa kukungqubana okuqhelekileyo bungonakalisa i-pulp yamazinyo. Nangona kunjalo, ipropati yokuzilola ngokwayoi-corundum emhlophe(ukuhlala kuphuhliswa imiphetho emitsha ngexesha lokusetyenziswa) kuqinisekisa ukuba i-bur ihlala ibukhali rhoqo. Idatha yeklinikhi evela kwisibhedlele samazinyo saseBeijing ibonisa ukuba ngexesha lonyango lweengcambu kusetyenziswa i-white corundum burs, ubushushu be-pulp yamazinyo bunyuka nge-2°C kuphela, ngaphantsi kakhulu komda wokhuseleko lwamazwe ngamazwe we-5.5°C.
III. Iingubo zokufakelwa: Ukunika amalungu okwenziwa “isikrweqe sedayimani”
Eyona ndlela ibalaseleyo yokusebenzisa i-corundum emhlophe kwezonyango kukukwazi kwayo ukunika amalungu okwenziwa "ubomi besibini." Isebenzisa ubuchwepheshe bokutshiza nge-plasma, i-corundum micropowder emhlophe itshizwa nge-melt-spray kumphezulu we-titanium alloy joint kubushushu obuphezulu, yenze umaleko okhuselekileyo oxineneyo onobukhulu obuyi-10-20 microns. Ubuchule bale sakhiwo bulele koku kulandelayo:
Umaleko ongaphandle oqinileyo uyamelana nokungqubana kwemihla ngemihla.
Isiseko esiqinileyo sangaphakathi siyayifunxa imiphumo engalindelekanga.
Ulwakhiwo lwe-microporous lukhuthaza ukukhula kweeseli zamathambo ezijikelezileyo.
Iimodeli kwilebhu yaseJamani zibonise ukuba emva kwemizila yokuhamba ezizigidi ezi-5, ukuguguleka kwedolo eligqunywe nge-corundum emhlophe kwakuyi-1/8 kuphela ye-titanium ecocekileyo. Ilizwe lam lifake obu buchwephesha kwinkqubo yalo ethi "Green Channel for Innovative Medical Devices" ukusukela ngo-2024. Amalungu esinqe amhlophe aveliswe ekhaya axabisa ngama-40% kuneemveliso ezingeniswe kwamanye amazwe, nto leyo enceda amakhulu amawaka ezigulana ezinezifo zamathambo.
IV. I-White Corundum "I-High-Tech" kwiKliniki yeXesha elizayo
Ezonyango Phakathi kwenguquko yetekhnoloji, i-white corundum ivula imida emitsha:
Isikali esincinciukupolisha kwe-corundum emhlophe Iiarhente zisetyenziswa ekwenzeni iitships zokulandelelanisa izakhi zofuzo, nto leyo enyusa ukuchaneka kokufunyanwa ukusuka kwi-99% ukuya kwi-99.99%, nto leyo enceda ekuhlolweni komhlaza kwangethuba.
I-vertebrae yokwenziwa eprintiweyo nge-3D equka ulusu olumhlophe oluqinisiweyo lwe-corundum inika amandla okucinezelwa kabini kunamathambo endalo, nto leyo enika ithemba kwizigulana ezine-spinal tumor.
Iingubo ze-biosensor zisebenzisa iipropati zokukhusela ze-corundum emhlophe ukuze kufezekiswe ukuhanjiswa kwemiqondiso ye-interface yengqondo nekhompyutha ngaphandle kokuphazamiseka.
Iqela lophando laseShanghai lide laphuhlisa izikrufu zamathambo e-corundum ezimhlophe ezibolayo—eziqala ngokubonelela ngenkxaso eqinileyo kwaye zikhuphe kancinci ii-ion ze-aluminium ezikhuthaza ukukhula njengoko ithambo liphola. “Kwixesha elizayo, utyando lokuqhekeka lunokuphelisa imfuneko yotyando lwesibini lokususa isikrufu,” utshilo uGqr. Wang, inkokeli yeprojekthi, ngelixa enika idatha yovavanyo evela kwi-rabbit tibias: emva kweeveki ezisibhozo, umthamo wesikrufu wehle ngama-60%, ngelixa uxinano lwethambo elitsha lwaluphindwe kabini kunolweqela lolawulo.
