Indima entsha ye-White Corundum kwi-Revolution yeTekhnoloji yezoNyango
Ngoku, ayisayi kugqabhuka nokuba iye yawa—imfihlelo ikule ‘safire emhlophe’ yokwaleka.” “Isafire emhlophe” awayebhekisela kuyo yayiyicorundum emhlopheesetyenziswa kwishishini lokupholisha intsimbi. Xa le crystal ye-aluminium oxide, enobunzima be-Mohs ye-9.0 kunye nokuhlanjululwa kweekhemikhali ze-99%, yangena kwintsimi yezonyango, i-revolution ethule kwizinto zonyango yaqala.
1. Ukususela kwi-Industrial Grinding Wheels ukuya kwiZidibaniselwano zoMntu: I-Revolution ye-Cross-Border kwiNzululwazi yezinto
Usenokuba uyazibuza ukuba i-abrasive ekuqaleni yayisetyenziselwa ukusika isinyithi ibe yinto entsha yecandelo lezonyango. Ukuyibeka ngokulula, eyona nto iphambili kusukelo lweteknoloji yezonyango “yi-biomimeticism”—ukufumana izinto ezinokudityaniswa nomzimba womntu kunye nokumelana namashumi eminyaka yokuguga.I-corundum emhlophe, kwelinye icala, ino "isakhiwo esomeleleyo":
Ubunzima bayo bukhuphisana noboidayimani, kwaye ukuxhathisa kwayo ukunxiba kudlula amaxesha amathathu eentsimbi zemveli zentsimbi.
I-inertness yayo yeekhemikhali yomelele kakhulu, ithetha ukuba ayiboli, ayirusi, okanye ibangele ukwaliwa emzimbeni womntu.
Indawo yayo efana nesipili yenza kube nzima ukuba ibhaktheriya inamathele, ukunciphisa umngcipheko wokosuleleka emva kokuhlinzwa.
Kwangoko ngo-2018, iqela lezonyango eShanghai laqala ukuhlola ukusetyenziswa kwecorundum-coated emhlopheamalungu. Utitshala womdaniso oye watshintshwa inyonga ngokupheleleyo wabuyela eqongeni emva kweenyanga ezintandathu emva kotyando. “Amalungu am entsimbi ayedla ngokundinxibisa kangangokuba inyathelo ngalinye lalingathi liqhekeza iglasi. Okwangoku, ixesha lokuphila kweziwhite corundum-ceramicAmalungu adityanisiweyo adlule iminyaka engama-25, phantse aphindwe kabini kunalawo enziwe ngezinto eziqhelekileyo.
II. "Umgcini ongabonakaliyo" kwiNgcebiso yeScalpel
Uhambo lwezonyango lwe-White corundum lwaqala ngokuguqulwa kwayo ngokukhawuleza kwezixhobo zonyango. Kwindibano yocweyo yokwenziwa kwezixhobo zonyango, uMlawuli woBugcisa uLi walatha kuluhlu lwezixhobo zotyando ezibenyezelayo kwaye wachaza, “Emva kokupolisha izixhobo zentsimbi engenakutyiwa.i-white corundum micropowder, uburhabaxa bomphezulu buncitshiswe bube ngaphantsi kwe-0,01 microns—enobugudileyo kunobungqingqwa beenwele zomntu omnye wamawaka alishumi.” Lo mphetho wokusika ogudileyo wenza utyando lube mtyibilizi njengemela eshushu ngebhotolo, ukunciphisa umonakalo wezicubu ngama-30% kwaye kukhawulezisa ukuphiliswa kwesigulana.
Isicelo esiguqukayo ngakumbi kukugqirha wamazinyo. Ngokwesiqhelo, xa usebenzisa i-diamond abrasive burs ukucola amazinyo, ubushushu obuveliswa kukukhuhlana okuphakamileyo kunokonakalisa intlama yamazinyo. Nangona kunjalo, ipropathi yokuzilola yecorundum emhlophe(ukuphuhlisa imiphetho emitsha rhoqo ngexesha lokusetyenziswa) iqinisekisa ukuba i-bur ihlala ibukhali. Idatha yezonyango evela kwisibhedlele samazinyo saseBeijing ibonisa ukuba ngexesha lokunyangwa kweengcambu kusetyenziswa i-corundum burs emhlophe, iqondo lokushisa le-pulp yamazinyo liyenyuka nge-2 ° C kuphela, ngaphantsi komda wokhuseleko lwamazwe ngamazwe we-5.5 ° C.
III. Iingubo zokufakelwa: Ukunika amalungu enziweyo "Isikrweqe sedayimane"
Esona sicelo sicingelwayo sonyango se-white corundum kukukwazi ukunika amalungu okwenziwa "ubomi besibini." Ukusebenzisa iteknoloji yokutshiza iplasma, i-white corundum micropowder inyibilika-itshizwe kwindawo edibeneyo ye-titanium alloy kwiqondo lobushushu obuphezulu, yenze umaleko oshinyeneyo okhuselayo oyi-10-20 microns. Ubuchule besi sakhiwo bulele koku:
Umaleko onzima wangaphandle uxhathisa ukukhuhlana kwansuku zonke.
Isiseko sangaphakathi esiqinileyo sifunxa iimpembelelo ezingalindelekanga.
Isakhiwo se-microporous sikhuthaza ukukhula kweeseli zethambo ezijikelezileyo.
Ukulinganisa kwibhubhoratri yaseJamani kubonise ukuba emva kwe-5 yezigidi zemijikelezo ye-gait, ukunxiba kweprosthesis yamadolo ehlanganiswe ne-corundum emhlophe yayiyi-1/8 kuphela ye-titanium ecocekileyo. ilizwe lam lifake le teknoloji kwiprogram yayo "I-Green Channel ye-Innovative Medical Devices" ukususela kwi-2024. Iingqungquthela ze-hip ezifakwe ekhaya ezimhlophe ze-corundum zifakwe kwi-40% ziphantsi kuneemveliso ezithunyelwa ngaphandle, zixhamla amakhulu amawaka ezigulane ezinezifo zamathambo.
IV. I-White Corundum "i-High-Tech" kwiKliniki yekamva
Unyango phakathi kwenguqu yetekhnoloji, i-white corundum ivula imida emitsha:
Nano-scaleukugulisa icorundum emhlophe ii-arhente zisetyenziselwa ukwenziwa kweetshiphusi zolandelelwano lwemfuza, ukwandisa ukuchaneka kokuchongwa ukusuka kwi-99% ukuya kwi-99.99%, ukuququzelela ukuhlolwa komhlaza kwangoko.
I-3D-eshicilelwe i-vertebrae eyenziweyo ebandakanya i-skeleton emhlophe ye-corundum inikezela ngokuphindwe kabini amandla acinezelayo ethambo lendalo, enika ithemba kwizigulane zomgogodla.
Iingubo ze-Biosensor ziphakamisa iipropati ezikhuselayo ze-corundum emhlophe ukufezekisa ukuhanjiswa kwe-zero-interference ye-brain-computer interface signals.
Iqela lophando laseShanghai lide laphuhlisa izikrufu zethambo le-corundum ezimhlophe ezinokuthi ziqale zibonelele ngenkxaso eqinileyo kwaye zikhulule ngokucothayo ukukhula-okukhuthaza ii-ion ze-aluminium njengoko ithambo liphilisa. "Kwixesha elizayo, utyando lokuphuka lunokuphelisa imfuno yokuhlinzwa okwesibini ukususa isikrufu," watsho uDkt Wang, inkokeli yeprojekthi, ngelixa ebonisa idatha yovavanyo kwi-rabbit tibias: emva kweeveki ezisibhozo, umthamo we-screw wehla nge-60%, ngelixa ubuninzi bethambo esanda kwakhiwa buphindwe kabini kwiqela lolawulo.
