Udindo Watsopano wa White Corundum mu Medical Technology Revolution
Tsopano, sichingaphwanyike ngakhale itagwetsedwa—chinsinsi chagona pa zokutira ‘zoyera za safiro’ zimenezi.” “Safiya woyera” amene anali kunena analiwhite corundumntchito mafakitale zitsulo kupukuta. Pamene aluminium oxide crystal iyi, ndi kuuma kwa Mohs kwa 9.0 ndi chiyero cha mankhwala a 99%, adalowa m'chipatala, kusintha kwachete kwa zipangizo zamankhwala kunayamba.
1. Kuchokera ku Magudumu Akupera Mafakitale kupita ku Malumikizidwe a Anthu: Kusintha kwa Border mu Sayansi Yazinthu
Mutha kukhala mukuganiza kuti abrasive yomwe idagwiritsidwa ntchito podula zitsulo idakhala bwanji chida chatsopano chachipatala. Kunena mwachidule, cholinga chachikulu chaumisiri wamankhwala ndi “biomimeticism” —kupeza zinthu zomwe zimatha kuphatikizana ndi thupi la munthu komanso kupirira kuwonongeka kwazaka zambiri.White corundum, kumbali ina, ili ndi "cholimba cholimba":
Kuuma kwake kumatsutsana ndidiamondi, ndipo kukana kwake kuvala kumaposa katatu kuposa zolumikizira zachitsulo zachikhalidwe.
Kusakhazikika kwake kwamankhwala kumakhala kolimba kwambiri, kutanthauza kuti sikuwola, kudzimbirira, kapena kuchititsa kukanidwa m'thupi la munthu.
Malo ake ngati galasi amachititsa kuti mabakiteriya asamagwirizane, kuchepetsa chiopsezo cha matenda a postoperative.
Kumayambiriro kwa 2018, gulu lachipatala ku Shanghai linayamba kufufuza kugwiritsa ntchitowoyera corundum-wokutidwazolumikizana. Mphunzitsi wovina yemwe adasinthidwa m'chiuno chonse adabwerera ku siteji miyezi isanu ndi umodzi pambuyo pa opaleshoni. “Maluni anga achitsulo ankandigwira mwamphamvu kwambiri moti poyenda pang’onopang’ono ndinkamva ngati ndikuphwanyika magalasi.” Panopa ndimangoiwala kuti pamene ndimavina alipo. Pakali pano, moyo wa iziwoyera corundum-ceramiczolumikizana zophatikizika zadutsa zaka 25, pafupifupi kuwirikiza kawiri zomwe zidapangidwa kale.
II. "Invisible Guardian" pa Tip ya Scalpel
Ulendo wachipatala wa White corundum unayamba ndi kusintha kwakukulu kwa zida zachipatala. Pamsonkhano wopanga zida zachipatala, Technical Director Li adalozera pamzere wa zida zonyezimira zopangira opaleshoni ndipo adalongosola, "Atapukuta zida zachitsulo zosapanga dzimbiri ndiwhite corundum micropowder, kukhwinyata kwake kumachepetsedwa kukhala ma microns ochepera 0.01—osalala kuposa kukhuthala kwa tsitsi la munthu limodzi ndi 10,000.” Kudulira kosalala kumeneku kumapangitsa kudula kwa maopaleshoni kukhala kosalala ngati mpeni wotentha kudzera batala, kuchepetsa kuwonongeka kwa minofu ndi 30% ndikufulumizitsa machiritso a odwala.
Ntchito yosintha kwambiri ili muudokotala wamano. Mwachizoloŵezi, pogwiritsira ntchito miyala ya diamondi popera mano, kutentha kobwera chifukwa cha kugundana kwakukulu kumatha kuwononga zamkati. Komabe, kudziletsa kunola katundu wawhite corundum(Kupanga m'mphepete mwatsopano nthawi zonse) kumatsimikizira kuti bur imakhalabe yakuthwa nthawi zonse. Zambiri zachipatala kuchokera ku chipatala cha mano ku Beijing zikuwonetsa kuti pochiza mizu pogwiritsa ntchito zoyera za corundum, kutentha kwa zamkati kwa mano kumakwera ndi 2 ° C kokha, kutsika kwambiri kuposa malire achitetezo apadziko lonse a 5.5 ° C.
III. Zopaka Zopangira: Kupatsa Zida Zopangira "Zida Za diamondi"
Kugwiritsa ntchito bwino kwachipatala kwa white corundum ndiko kuthekera kwake kupatsa ziwalo zopanga "moyo wachiwiri." Pogwiritsa ntchito umisiri wa plasma kupopera mbewu mankhwalawa, white corundum micropowder imasungunuka-sprayed pa titaniyamu aloyi olowa pamwamba pa kutentha kwambiri, kupanga wandiweyani zoteteza wosanjikiza 10-20 microns wandiweyani. Luso lakapangidwe kameneka lagona mu:
Chosanjikiza chakunja cholimba chimalimbana ndi mikangano ya tsiku ndi tsiku.
Kulimba kwamkati mkati kumatengera zosayembekezereka.
Mapangidwe a microporous amalimbikitsa kukula kwa maselo ozungulira mafupa.
Zofananira mu labotale yaku Germany zidawonetsa kuti pambuyo pa ma 5 miliyoni oyenda mozungulira, kuvala kwa prosthesis ya bondo yokutidwa ndi corundum yoyera kunali 1/8 yokha ya titaniyamu yoyera. dziko langa laphatikiza ukadaulo uwu mu pulogalamu yake ya "Green Channel for Innovative Medical Devices" kuyambira 2024. Zolumikizana zam'chiuno zoyera za corundum zokhala ndi chiuno ndi 40% zotsika mtengo kuposa zogulitsa kunja, zomwe zimapindulitsa mazana masauzande a odwala omwe ali ndi matenda a mafupa.
IV. White Corundum "High-Tech" mu Clinic ya Tsogolo
Medical Pakati pa kusintha kwaukadaulo, white corundum ikutsegula malire atsopano:
Nano-scalekupukuta korundum woyera Othandizira amagwiritsidwa ntchito popanga tchipisi ta jini, ndikuwonjezera kulondola kuchokera pa 99% mpaka 99.99%, ndikuwongolera kuyezetsa koyambirira kwa khansa.
Mafupa opangidwa ndi 3D opangidwa ndi 3D ophatikiza mafupa oyera a corundum amapereka kuwirikiza kawiri mphamvu ya mafupa achilengedwe, kupereka chiyembekezo kwa odwala chotupa cha msana.
Zovala za Biosensor zimakulitsa mphamvu zoteteza za white corundum kuti zitheke kusokoneza zero-kusokoneza ma siginecha amtundu waubongo-makompyuta.
Gulu lofufuza ku Shanghai lapanganso zomangira zoyera za corundum zowola, zomwe poyamba zimapereka chithandizo cholimba ndikutulutsa pang'onopang'ono ma ayoni a aluminiyamu omwe amalimbikitsa kukula fupa likachira. "M'tsogolomu, opaleshoni ya fracture ikhoza kuthetsa kufunikira kwa opaleshoni yachiwiri kuti achotse wononga," adatero Dr. Wang, mtsogoleri wa polojekiti, pamene akuwonetsa deta yoyesera kuchokera ku kalulu tibias: pambuyo pa masabata asanu ndi atatu, voliyumu ya screw inachepa ndi 60%, pamene kuchuluka kwa fupa lopangidwa kumene kunali kawiri kawiri kuposa gulu lolamulira.
