Kafukufuku ndi Kugwiritsa Ntchito Zinthu Zatsopano za Mchenga wa Zirconia
Ponena za zipangizo zamafakitale, anthu wamba ambiri angaone nkhaniyi kukhala yosasangalatsa, koma kwenikweni pali zovuta zambiri.zirconiaMwachitsanzo. Kale, anthu ankaganiza kuti imagwiritsidwa ntchito pazinthu monga mipeni yadothi ndi mano opangidwa ndi dothi, chinthu cholimba komanso chowala. Koma kwa ife omwe timagwira ntchito yofufuza ndi kupanga zinthu komanso kugwiritsa ntchito mafakitale, ndi chuma chamtengo wapatali. Zinthu zatsopano zopangidwa ndi mchenga wa zirconia zomwe zatuluka m'zaka zaposachedwa, makamaka, zathetsa mavuto akuluakulu ndipo zimapereka mwayi wogwiritsa ntchito bwino.
Ndikukumbukira kupita ku chiwonetsero cha mafakitale zaka ziwiri zapitazo ndikucheza ndi mainjiniya waluso yemwe adagwira ntchito pazinthu zosagwira ntchito kwa zaka zambiri. Anamenya ntchafu yake nati, "Hei, m'bale, sukumvetsa! Makampani opanga zitsulo tsopano akuika zinthu zofunika kwambiri! Kutentha kukukwera kwambiri, ndipo chilengedwe chikukulirakulira. Zipangizo zachikhalidwe sizingathe kuzisamalira. Mwachitsanzo, tenga zirconia. Aliyense amadziwa kuti ndi yabwino kwambiri—yolimba kutentha kwambiri komanso yokhazikika pa mankhwala. Koma mchenga wa zirconia wopangidwa pogwiritsa ntchito njira zachikhalidwe ulibe chiyero, kusafanana kwa tinthu tating'onoting'ono, kapena kusakhazikika. Ndi wokwera mtengo kwambiri, zomwe zimapangitsa kuti zikhale zovuta kugwiritsa ntchito. Nthawi zambiri, zimakhala ngati 'chifuniro chilipo, luso sililipo.'"
Iye anafika pachimake. Ichi ndiye cholinga choyambirira cha kafukufuku wathu watsopano wa mchenga wa zirconia ndi chitukuko—kodi si kuthetsa mavuto akale awa?
Ndiye kodi luso lamakono lili kuti kwenikweni? Ndiloleni ndifotokoze.
Choyamba, "pakati" payenera kusintha. Zirconia yakale inali ndi vuto: kapangidwe kake ka kristalo kanali kosakhazikika. Kutentha kukasinthasintha, kumatha "kulimbana" mkati, ndikupanga mikwingwirima yaying'ono. Pakapita nthawi, magwiridwe antchito adachepa. Njira yathu yatsopano ikuphatikiza kusintha kwakukulu pakupanga ndi kukonza. Mwa kuyambitsa zokhazikika zapamwamba kwambiri, monga yttrium, kuphatikiza ndi sintering yotentha kwambiri komanso njira zamakono zophwanya ndi kugawa magulu, tapeza chinthu chodabwitsa ichi: "zirconia yokhazikika pang'ono." Mwanjira ina, zili ngati kupanga "chigoba chachitsulo" mkati mwa tinthu ta zirconia, kuonetsetsa kuti ndi zolimba zikafunika komanso zopindika zikafunika, mosiyana ndi zinthu zofooka, zomwe zimawonongeka mosavuta zakale. Kuphatikiza apo, chiyero chikuwonjezeka pang'onopang'ono, ndi kuchuluka kwa zodetsa kumasungidwa pamlingo wotsika kwambiri.
Kachiwiri, chisamaliro chiyenera kuperekedwanso pa mawonekedwe ndi mawonekedwe. Mchenga wa zirconia watsopano umagogomezera kwambiri mawonekedwe—osati pa mpikisano wokongoletsa kokha, komanso pankhani ya mawonekedwe a tinthu ndi kugawa kwa kukula. Tinthu tating'onoting'ono tomwe kale tinkaoneka ngati "opanda kukula," tinali vuto lalikulu pakugwiritsa ntchito molondola. Tsopano, kudzera mu njira zamakono monga kugaya mpweya ndi magulu a centrifugal, titha kupanga ufa wa zirconia wozungulira wokhala ndi tinthu tating'ono tofanana kwambiri. Tengani pang'ono ndipo umamveka ngati ufa wabwino kwambiri, koma kuuma kwake ndi kwakukulu kwambiri. Kufanana kumeneku kumapereka zabwino zambiri: kaya kugwiritsidwa ntchito ngati chophimba kapena chopopera, zotsatira zake zimakhala zokhazikika komanso zofanana, popanda kugwiritsa ntchito kosagwirizana.
Kulankhula zinthu zazikulu n'kopanda phindu; chitukuko chiyenera kugwiritsidwa ntchito moyenera. Zinthu zatsopanozimchenga wa zirconiatsopano akufunidwa kwambiri m'magawo osiyanasiyana apamwamba.
Choyamba, kupangira molondola ndikofunikira kwambiri, makamaka pazigawo zopyapyala komanso zovuta kwambiri monga mabala a injini ya ndege ndi mabala a turbine ya gasi. Kutentha kwa kupangira kumafika madigiri Celsius oposa 1,000, zomwe zimapangitsa kuti chipolopolo cha nkhungu chikhale chofunikira kwambiri. Ma topcoat opangidwa ndi mchenga watsopano wa zirconia awa azikhala olimba komanso kutentha koyenera. Izi zimathandizira kwambiri kukongoletsa pamwamba pa kupangira, zomwe zimapangitsa kuti zolakwika monga kunyamula mchenga ndi ma burrs zisawonekere, zomwe zimachepetsa kwambiri mtengo womaliza pambuyo pake. Akatswiri odziwa bwino ntchito amati, "Pogwiritsa ntchito mchenga watsopanowu, ntchitoyi ndi yodabwitsa kwambiri!"
Ntchito ina ndi yapamwamba kwambirikupera ndi kupukuta. Magalasi athu a foni yam'manja, lenzi ya kamera, ndi ma wafer osiyanasiyana a semiconductor amafuna malo osalala kwambiri; ngakhale kukanda pang'ono kungapangitse kuti zigwe. Zirconium oxide micropowder yatsopano, yokhala ndi kuuma kwake kwakukulu, kukula kwa tinthu tofanana, komanso mphamvu zabwino kwambiri zamakemikolo ndi makina, ndi madzi opukutira ogwira ntchito kwambiri. Kuchuluka kwa kuchotsedwa kumayendetsedwa bwino, ndipo kukana kukanda ndi kochepa, zomwe zimapangitsa kuti malo osalala akhale olimba kwambiri pamlingo wa nanoscale kapena atomiki. Mwachidule, chophimba cha foni yanu chimamveka chosalala kwambiri chifukwa cha ichi.
Palinso zokutira zotchingira kutentha. Kodi injini zamlengalenga ndi ma turbine a gasi zingapirire bwanji kutentha kotereku? Zigawo zazikulu zimapopedwa ndi "jekete loteteza kutentha." Chimodzi mwa zinthu zazikulu zomwe zimagwiritsidwa ntchito mu jekete iyi ndi zirconium oxide-based ceramics. Mchenga watsopano wa zirconium oxide, wokhala ndi kukana kutentha kwambiri komanso kukhazikika kwa gawo, ndiye chinthu chofunikira kwambiri pokonzekera ufa wapamwamba kwambiri wa zokutira uwu, womwe umagwirizana mwachindunji ndi magwiridwe antchito a injini komanso moyo wake.
Kuphatikiza apo, imapezeka mu zoumba zadothi zomwe zimagwiritsidwa ntchito popanga malo ovuta, zinthu zotsutsana ndi chilengedwe, komanso zinthu zina zamankhwala. Ntchito zake zikuchulukirachulukira.
M'tsogolomu, ndikukhulupirira kuti njira yatsopano yopangira mchenga wa zirconia idzakhala yokulirapo. Ndi kupita patsogolo mwachangu m'mafakitale monga photovoltaics, semiconductor chips, ndi aerospace, zofunikira pakugwira ntchito kwa zipangizozi zidzakhala zovuta kwambiri. Zinthu za mchenga wa zirconia zokhala ndi makhalidwe oyera, abwino, ofanana, komanso magwiridwe antchito owongolera mosakayikira zidzapangidwa. Mwina tsiku lina, zidzawala m'malo omwe sitingathe kuwaganizira pakadali pano.
Choncho, musanyoze tinthu tating'onoting'ono ta mchengati. Tili ndi nzeru zambiri ndipo tingalimbikitse mafakitale akuluakulu. Kufunika kwa luso lamakono kuli pakugwiritsa ntchito mphamvu zonse za zinthu kuti zikwaniritse zofunikira za nthawi yathu ino.
