Kusintha Siliva ndi Mkuwa mu Ceramic Capacitor Electrodes: Mzere Wothira Magazi wa Zhenhua Vacuum Wakhala Wokhazikika Kwa Zaka 14

Pakupanga ma capacitor a ceramic, ma electrode amapangidwa mwachizolowezi kudzera mu kusindikiza phala la siliva kutsatiridwa ndi kuumitsa ndi kusungunula. Popeza phala la siliva lili ndi siliva wambiri ndipo limapanga zigawo zokhuthala za electrode, kugwiritsa ntchito siliva konse kumakhala kwakukulu, zomwe zimapangitsa kusinthasintha kwa mitengo ya siliva kukhala chinthu chomwe chimakhudza mtengo wa zinthu za electrode.

Kwa zaka makumi awiri zapitazi, kukwera kwa mitengo ya siliva kosalekeza kwakhala chinthu chosapeŵeka kwa opanga ma capacitor a ceramic. Kutengera mitengo yapakati pa siliva yapadziko lonse lapansi, mtengo wapakati wa siliva unali pafupifupi RMB 3,350/kg mu 2008, kukwera kufika pafupifupi RMB 9,190/kg mu 2025—kuwonjezeka kwa pafupifupi nthawi 2.7 pazaka 17.

Kupatula mtengo wokwera wa siliva, zofooka za njira yodziwika bwino yopangira siliva zawonekeranso kwambiri. Kusindikiza, kuumitsa, ndi kupukuta kumaphatikizapo njira zingapo zogwirira ntchito, kusamalira zinthu mozama komanso kugwira ntchito ndi manja. Nthawi yomweyo, zofunikira kwambiri pa chilengedwe komanso kufunikira kwa kupanga zinthu zokha zikulimbikitsa opanga kuti ayang'anenso zinthu za electrode ndi njira zosungiramo zinthu, poganizira kwambiri kuchepetsa kugwiritsa ntchito siliva, kufupikitsa unyolo wa njira, komanso kukwaniritsa kupanga zinthu zambiri zokha.

Ngakhale kuti makampaniwa ankadalira kwambiri kukonza phala la siliva, Zhenhua Vacuum ndi kasitomala wake anali atayamba kale kufufuza njira ya "kulowetsa mkuwa m'malo mwa siliva".

Kuganizira Patsogolo: Kufunika kwa Makasitomala Kunali Patsogolo pa Msika

Mu 2008, pamene mavuto azachuma padziko lonse lapansi adafalikira m'misika komanso kusatsimikizika kudakula, wopanga wamkulu wamakampani opanga ma ceramic capacitor apamwamba adayamba kuwunika momwe zinthu zingakhudzire nthawi yayitali chifukwa cha kusinthasintha kwa mitengo ya zinthu zopangira ndi kusintha kwa njira zopangira zinthu asanakwere mitengo yasiliva.

Chifukwa chake kasitomala adaphatikiza kukonza njira zama electrode mu njira yake yopangira zinthu kwa nthawi yayitali: kuchepetsa kudalira siliva ndi kusokonezeka kwa mitengo ya siliva pamene akusunga magwiridwe antchito ndi kudalirika kwa zinthu; komanso nthawi yomweyo, kusintha kupanga ma electrode kuchoka pa ntchito zamanja ndi zamanja kupita ku kupanga zinthu zodziyimira pawokha komanso zokhazikika kuti akonze kusinthasintha kwa zinthu, kukhazikika kwa njira, komanso kuthekera kopereka zinthu kwa nthawi yayitali.

Kasitomala adapita ku Zhenhua Vacuum kuti afufuze pamodzi njira yatsopano yaukadaulo: Kodi chinthu china chingagwiritsidwe ntchito popanga ma electrode a ceramic capacitor, pomwe njira yatsopano yoyikamo ndi zida zopangira zokha zingathandize kupanga zinthu kwa nthawi yayitali, kokhazikika, komanso kokwera mtengo?

Kufufuza Koyambirira: Kukonzanso Njira ya Electrode ndi Mkuwa

Poyamba ntchitoyi, panalibe njira yodziwika bwino yopezera njira yothetsera vutoli. Zida zina zinkafunika kuti pakhale magetsi abwino komanso ubwino wa mtengo wake, komanso kuti pakhale kulimba kwabwino kwambiri komanso kudalirika kwa nthawi yayitali. Njira yatsopanoyi iyeneranso kugwirizana ndi kupanga zinthu zokha.

Pambuyo poyesa ukadaulo kangapo, mkuwa unapezeka ngati njira yabwino. Mphamvu yake yamagetsi ndi yofanana ndi ya siliva ndipo mtengo wake wa zinthu ndi wotsika kwambiri. Komabe, mkuwa umakhala ndi okosijeni kutentha kwambiri, zomwe zikutanthauza kuti njira yachikhalidwe yopangira phala la siliva singathe kungobwerezedwanso. Njira yoyikamo, magawo a njira, ndi zida zopangira zonse zinayenera kupangidwa mwatsopano.

Panthawiyo, panalibe zitsanzo zodziwika bwino za kupanga ma electrode amkuwa ambiri a ma capacitor a ceramic. Zipangizo, ukadaulo wa njira, ndi chitukuko cha zida zonse zinayenera kuyambira pansi. M'malo moyembekezera kuti yankho la zinthuzo limalizidwe, Zhenhua Vacuum inayamba kugwira ntchito kuyambira pachiyambi cha polojekitiyi ndipo inagwira ntchito limodzi ndi kasitomala kuti akhazikitse njira yaukadaulo. Mayeso a zitsanzo, kutsimikizira utoto, ndi chitukuko cha njira zopangira zinthu zambiri zinachitika limodzi ndi uinjiniya wa zida, zomwe zinathandiza kuti njira yoyikamo ndi mzere wopanga zinthu zisinthe pamodzi.

Pomaliza, onse awiri adasankha magnetron sputtering (PVD) ngati ukadaulo waukulu. Filimu yoyikidwayo imapereka kukanikiza kwamphamvu ku substrate ndipo imalola kuti gawo la electrode yamkuwa liyikidwe mwachindunji pamwamba pa ceramic popanda chomangira chachilengedwe chomwe chimagwiritsidwa ntchito mu siliva. Izi zimachotsa kufunikira kwa zosungunulira ndi kusungunuka kwawo, komanso kuchotsa sitepe yotenthetsera kutentha kwambiri, zomwe zimapangitsa kuti njira youma ikhale yoyera komanso yosawononga chilengedwe poyerekeza ndi njira yonyowa yachikhalidwe.

Pofuna kupititsa patsogolo ntchito yoyika zinthu komanso kupanga zinthu, Zhenhua idapanga njira yopangira zinthu zopitirira mbali ziwiri. Zinthu zadothi zikalowa mu vacuum system, mbali zonse ziwiri zimatha kuphimbidwa popanda kusinthidwa ndi manja, pomwe kusamutsa zinthu mosalekeza kumalumikiza magawo osiyanasiyana a ntchito. Njira yowuma iyi imalowa m'malo mwa njira zambiri zonyowa za "kusindikiza siliva → kuumitsa → kusinja," zomwe zimapangitsa kuti ntchito yonse ikhale yosavuta komanso kukonza kusinthasintha kwa ntchito komanso kugwira ntchito bwino kwa ntchito.

Mu 2012, zidazo zinaperekedwa bwino. Kuyambira kukambirana koyamba zaukadaulo ndi chitukuko cha njira mpaka kukhazikitsa ndi kukhazikitsa mzere wopanga, ntchitoyi inatenga pafupifupi zaka ziwiri.

Kutsimikizika Kwa Nthawi Yaitali: Zaka 14 Zopanga Zinthu Mosalekeza

Kuyambira mu Seputembala 2026, chingwe cholumikizira cha mbali ziwiri chomwe chinaperekedwa mu 2012 chikugwirabe ntchito pamalo a kasitomala ndipo chikuthandizira kupanga zinthu zambiri mokhazikika. Ngakhale kuti chikukwaniritsa zofunikira pakuphimba zinthu mofanana, kupanga zinthu zokha, komanso kupanga zinthu zambiri, yankho la "siliva wolowa m'malo mwa mkuwa" limachepetsa kwambiri kudalira siliva wachitsulo chamtengo wapatali ndikuchepetsa ndalama zogulira zinthu zama electrode, komanso likugwirizana ndi zofunikira pakupanga zinthu zoyera komanso zosamalira chilengedwe. Pambuyo pa zaka 14 zogwira ntchito mosalekeza, zidazi zapereka chitsimikizo cha nthawi yayitali cha njira ndi njira yothetsera zinthu malinga ndi momwe zimagwirira ntchito bwino, mtundu wa utoto, kudalirika kwa kupanga, komanso kukhazikika kwa kupanga zinthu zambiri.

Panthawiyo, makampani akunyumba anali akadali kumayambiriro kwa kumvetsetsa ndikugwiritsa ntchito njira ya mkuwa ndi ma electrode, ndipo opanga ambiri akupitiliza kudalira kukonza ma phala asiliva. Komabe, m'zaka zaposachedwa, kukwera kwa kukakamizidwa kwamitengo kuchokera ku phala lasiliva kwathandizira kusintha kwa makampaniwo kukhala "olowa m'malo mwa siliva," zomwe zapangitsa kuti zida zothira madzi zikhale njira yofunidwa kwambiri yopangira ma electrode a ceramic capacitor. Njira yomweyi yaukadaulo yasintha kuchoka pa kufufuza koyambirira kupita ku cholinga chachikulu chamakampani lerolino - ndi zaka 14 zotsimikizira kupanga pakati.

Kwa kasitomala, ubwino wake wakhala wa nthawi yayitali. Kuwonjezera pa kuchepetsa mwachindunji ndalama zogulira zinthu, njira yopangira zinthu yachotsa kukhudzidwa kwake ndi kusinthasintha kwa mitengo ya siliva zaka 14 patsogolo pa makampani ambiri. Kasitomala adapezanso mwayi woyambirira wotsatira malamulo okhudza chilengedwe komanso kupanga zinthu zokha. Ngakhale opanga ambiri ayamba kukumana ndi kukakamizidwa kwakukulu kuchokera ku mitengo ya siliva ndi kusintha kwa njira, kasitomala uyu wakhala akusunga kale kupanga kokhazikika ndi ukadaulowu kwa zaka 14.

Pulojekitiyi inali imodzi mwa ntchito zoyambirira za Zhenhua Vacuum zaukadaulo wophatikizana wopitilira mbali ziwiri popanga ma capacitor a ceramic. Poganizira za malo opangira mafakitale am'nyumba mu 2012, kukhazikitsidwa kwake bwino kwa uinjiniya kunayimira kupita patsogolo koyambirira pakugulitsa ukadaulo wa mkuwa ndi ma electrode. Inawonetsa njira yoyang'ana patsogolo ya Zhenhua Vacuum pakupanga njira ndi kugwiritsa ntchito ukadaulo. Kudzera mu kupanga zida, kutumiza bwino, komanso zaka 14 zotsimikizira kupanga zinthu zambiri, pulojekitiyi idakhazikitsa malo olimba oyamba a Zhenhua Vacuum mu ntchito zophimba ma capacitor a ceramic, pomwe ikupereka chidziwitso chamtengo wapatali cha nthawi yayitali pakupanga zida pambuyo pake, kukonza njira, komanso kusintha kosalekeza.
