Basa Idzva reWhite Corundum muKuchinja kweTekinoroji yeMishonga
Zvino, harizotsemuki kunyangwe rikadonhedzwa—chakavanzika chiri mujira iri re'safire chena'.” “Safire chena” yaaitaura nezvayo yaivecorundum chenainoshandiswa mukupukuta simbi yeindasitiri. Apo iyi kristalo yealuminium oxide, ine kuomarara kweMohs kwe9.0 uye kuchena kwemakemikari kwe99%, yakapinda mubazi rezvekurapa, shanduko yakanyarara muzvinhu zvekurapa yakatanga.
1. Kubva paMavhiri ekukuya eIndasitiri kusvika paMajoini eVanhu: Kuchinja-chinja kweSainzi yezvinhu
Ungave uchishamisika kuti chigunwe chakamboshandiswa pakucheka simbi chave sei chinhu chitsva chinodiwa mune zvokurapa. Zvichitaurwa zviri nyore, chinangwa chikuru chehunyanzvi hwekurapa i "biomimeticism" - kutsvaga zvinhu zvinogona kubatana nemuviri wemunhu uye kutsungirira makumi emakore ekusakara.Corundum chena, kune rumwe rutivi, ine "chimiro chakasimba":
Kuoma kwayo kunokwikwidzana nekwedhaimani, uye kusakara kwayo kunopfuura katatu kupfuura majoini esimbi echinyakare.
Kusashanda kwayo kwemakemikari kwakasimba zvikuru, zvichireva kuti haiori, haikanganisi, kana kukonzera kurambwa mumuviri wemunhu.
Nzvimbo yayo yakaita segirazi inoita kuti zviomere mabhakitiriya kubatana, zvichideredza njodzi yehutachiona mushure mekuvhiyiwa.
Kubva mugore ra2018, timu yezvekurapa muShanghai yakatanga kuongorora kushandiswa kweyakaputirwa necorundum chenamajoini. Mudzidzisi wekutamba akagadziriswa hudyu zvachose akadzokera pachikuva mwedzi mitanhatu mushure mekuvhiyiwa. "Majoini angu esimbi aimbondinetsa zvekuti nhanho imwe neimwe yainzwa sekunge girazi riri kupwanyika. Iye zvino, ndinenge ndakanganwa kuti aripo pandinotamba." Parizvino, hupenyu hweizvichena corundum-ceramicMajoini akasanganiswa adarika makore makumi maviri nemashanu, anenge akapetwa kaviri pane echinyakare.
II. "Murindi Asingaonekwi" ari pamucheto weScalpel
Rwendo rwekurapa rweWhite corundum rwakatanga nekushanduka kukuru kwezvishandiso zvekurapa. Mumusangano wekugadzira zvishandiso zvekurapa, Mutungamiriri weTechnical Li akanongedzera kumutsara wemagetsi ekuvhiya anopenya ndokutsanangura kuti, “Mushure mekupukuta midziyo yesimbi isina ngura neupfu hwe corundum chena, kuomarara kwemusoro kunoderedzwa kusvika pasi pe 0.01 microns—kunopfava kupfuura 1.5000 paukobvu hwebvudzi remunhu.” Iyi nzira yekucheka yakapfava zvikuru inoita kuti kucheka kwekuvhiya kuve kwakapfava sebanga rinopisa kuburikidza nebota, zvichideredza kukuvara kwenyama ne30% uye zvichikurumidzisa kuporesa kwemurwere zvakanyanya.
Imwe nzira inochinja zvakanyanya ndeyekurapa mazino. Kazhinji, kana uchishandisa dhayi remadhaimani rinokwesha mazino, kupisa kunokonzerwa nekukweshana kwemazino kunogona kukuvadza pulp yemazino. Zvisinei, hunhu hwekuzvirodza hwecorundum chena(kugara uchigadzira mipendero mitsva panguva yekushandisa) zvinoita kuti bundu rirambe rakapinza nguva dzose. Ruzivo rwekiriniki kubva kuchipatara chemazino cheBeijing runoratidza kuti panguva yekurapwa kwemidzi yegumbo uchishandisa mabundu machena ecorundum, tembiricha yepulp yemazino inokwira ne2°C chete, iri pasi pemuganhu wekuchengetedzwa kwenyika we5.5°C.
III. Mapendi ekuisa mudumbu: Kupa Nhengo dzekugadzira "Dhaimondi Yekudzivirira"
Kushandiswa kwakanyanya kwe white corundum pakurapa ndiko kugona kwayo kupa nhengo dzekugadzira "hupenyu hwechipiri." Ichishandisa tekinoroji yekupfapfaidza plasma, white corundum micropowder inonyungudutswa-inopfapfaidzwa pamusoro petitanium alloy joint pamusoro pekupisa kwakanyanya, zvichiita kuti pave nechikamu chakasimba chekudzivirira chine ukobvu hwe 10-20 microns. Unyanzvi hwechivakwa ichi huri mu:
Chikamu chekunze chakaoma chinodzivirira kukweshana kwezuva nezuva.
Hwaro hwakasimba hwemukati hunotora migumisiro isingatarisirwi.
Maumbirwo emapfupa ari mukati memasero aya anobatsira kukura kwemasero emapfupa akapoteredza.
Kufungidzira kwakaitwa murabhoritari yekuGermany kwakaratidza kuti mushure mekufamba kwemamiriyoni mashanu, kupfeka kwebvi rakaputirwa necorundum chena kwaingova 1/8 chete yetitanium chaiyo. Nyika yangu yakaisa tekinoroji iyi muchirongwa chayo che "Green Channel for Innovative Medical Devices" kubvira 2024. Majoini ehudyu machena akagadzirwa necorundum akachipa ne40% pane zvigadzirwa zvinotengeswa kunze kwenyika, zvichibatsira mazana ezviuru zvevarwere vane zvirwere zvemapfupa.
IV. White Corundum "High-Tech" muKliniki yeRamangwana
Zvekurapa Pakati pekuchinja kwetekinoroji, corundum chena iri kuvhura miganhu mitsva:
Chikero cheNanokupukuta kwecorundum chena Mishonga iyi inoshandiswa mukugadzira machipisi ekuongorora majini, zvichiwedzera kururama kwekuonekwa kwechirwere kubva pa99% kusvika pa99.99%, zvichiita kuti kuongororwa kwegomarara kutange.
Mafupa emusana akadhindwa ne3D ane mapfupa machena akasimbiswa necorundum anopa simba rekudzvanya rakapetwa kaviri kupfuura mapfupa chaiwo, zvichipa tariro kune varwere vane bundu remusana.
Mapurasitiki ebiosensor anoshandisa hunhu hwekudzivirira hwewhite corundum kuti asatapurirane zviratidzo zve brain-computer.
Chikwata chekutsvagisa cheShanghai chakatogadzira masikuruu emapfupa machena ecorundum anogona kuora—ayo pakutanga anopa rutsigiro rwakasimba uye anoburitsa zvishoma nezvishoma maayoni ealuminium anokurudzira kukura sezvo pfupa richipora. "Munguva inotevera, kuvhiyiwa kwekutyoka kunogona kubvisa kudiwa kwekuvhiyiwa kwechipiri kubvisa sikuruu," akadaro Dr. Wang, mutungamiriri wepurojekiti, achipa ruzivo rwekuyedza kubva kutsuro tibias: mushure memavhiki masere, huwandu hwesikuruu hwakaderera ne60%, nepo huwandu hwepfupa idzva hwaive hwakapetwa kaviri kupfuura hweboka rekutonga.
