Kwimveliso ye-ceramic capacitor, ii-electrode ziveliswa ngokuprinta i-silver paste kulandele ukomisa kunye nokusila. Ngenxa yokuba i-silver paste inesixa esikhulu sesilivere kwaye ivelisa iileya ze-electrode ezixineneyo, ukusetyenziswa kwesilivere iyonke kukhulu, okwenza ukuguquguquka kwamaxabiso esilivere kube yinto echaphazela ngqo iindleko zezinto ze-electrode.
Kwiminyaka engamashumi amabini edlulileyo, ukunyuka okuqhubekayo kwamaxabiso esilivere kube yinto engenakuphepheka kubavelisi be-ceramic capacitor. Ngokusekelwe kumaxabiso esilivere aphakathi ngonyaka ehlabathi, ixabiso lesilivere eliphakathi lalimalunga ne-RMB 3,350/kg ngo-2008, lanyuka laya kuthi ga kwi-RMB 9,190/kg ngo-2025—ukwanda okumalunga namaxesha angama-2.7 kwiminyaka eli-17.
Ngaphaya kweendleko eziphezulu zesilivere, imida yenkqubo yesiqhelo yokuncamathisela isilivere nayo iye yabonakala ngakumbi. Ukuprinta, ukomisa, kunye nokucocwa kwenkunkuma kubandakanya amanyathelo amaninzi enkqubo, ukuphathwa kwezinto ngokunzulu kunye nokusebenza ngesandla. Kwangaxeshanye, iimfuno ezingqongqo zokusingqongileyo kunye nemfuno yokwenziwa okuzenzakalelayo ziqhuba abavelisi ukuba baphinde bahlole izixhobo ze-electrode kunye neenkqubo zokubeka, begxile ekunciphiseni ukusetyenziswa kwesilivere, ukunciphisa ikhonkco lenkqubo, kunye nokufezekisa imveliso yobuninzi ezenzekelayo kakhulu.
Nangona eli shishini lisaxhomekeke kakhulu ekucutshungulweni kwentlama yesilivere, iZhenhua Vacuum kunye nomthengi wayo babesele beqalile ukuhlola indlela "yokufaka isilivere endaweni yobhedu".
Ukucinga Ngaphambili: Imfuno Yabathengi Yayiphambili Kwimarike
Ngowama-2008, njengoko ingxaki yezemali yehlabathi yayisasazeka kwiimarike kwaye ukungaqiniseki kwanda, umenzi ophambili wasekhaya wee-capacitors zeseramikhi eziphezulu waqala ukuvavanya impembelelo enokubakho yexesha elide evela kukuguquguquka kwamaxabiso ezinto eziluhlaza kunye nokuguqulwa kwenkqubo yokuvelisa ngaphambi kokuba ukunyuka kwamaxabiso esilivere kudale uxinzelelo lweendleko ngqo.
Ngoko ke umthengi ufake ulungelelwaniso lwenkqubo ye-electrode kwisicwangciso sakhe sokuvelisa ixesha elide: ukunciphisa ukuxhomekeka kwisilivere kunye nokuvezwa kukuguquguquka kwexabiso lesilivere ngelixa kugcinwa ukusebenza kwemveliso kunye nokuthembeka; kwaye kwangaxeshanye, ukutshintsha imveliso ye-electrode ukusuka kwimisebenzi yesandla neyesandla ukuya kwimveliso yobuninzi ezenzekelayo, esemgangathweni ukuphucula ukuhambelana kwemveliso, uzinzo lwenkqubo, kunye nokukwazi ukubonelela ixesha elide.
Umthengi uye kwiZhenhua Vacuum ukuze badibane bahlole indlela entsha yobugcisa: Ngaba ezinye izinto zingasetyenziselwa ukuvelisa ii-electrode ze-ceramic capacitor, ngelixa inkqubo entsha yokufaka kunye nezixhobo zokwenza ngokuzenzekelayo zingenza ukuba kwenziwe imveliso yexesha elide, ezinzileyo, neyomthamo ophezulu?
Uphando Lwasekuqaleni: Ukwakha ngokutsha iNkqubo ye-Electrode ngeCopper
Ekuqaleni kwale projekthi, bekungekho sisombululo sikhoyo. Kwakufuneka ezinye izinto ukuze kubekho umbane oqhuba kakuhle kunye neenzuzo zeendleko, ngelixa kukwafuneka kunikezelwe ukunamathela okugqwesileyo kokugquma kunye nokuthembeka kwexesha elide. Le nkqubo intsha kwakufuneka ihambelane nemveliso ezenzekelayo.
Emva kovavanyo lobuchwephesha oluphindaphindeneyo, i-copper yavela njengokhetho olufanelekileyo. Ukuqhuba kwayo umbane kusondele kweyesilivere kwaye ixabiso layo lezinto liphantsi kakhulu. Nangona kunjalo, i-copper ithambekele ekutshisweni yi-oxidation kumaqondo obushushu aphezulu, oko kuthetha ukuba inkqubo yesiqhelo yokuncamathisela isilivere ayinakuphindwa nje. Indlela yokufaka, iiparameter zenkqubo, kunye nezixhobo zemveliso zonke kwafuneka zenziwe ngokutsha.
Ngelo xesha, bekungekho mizekelo yasekhaya emiselweyo yemveliso yobuninzi bee-electrode zobhedu kwii-capacitors ze-ceramic. Izixhobo, iteknoloji yenkqubo, kunye nophuhliso lwezixhobo zonke kwakufuneka ziqale ukusuka ekuqaleni. Endaweni yokulinda isisombululo sezinto ukuba sigqitywe, i-Zhenhua Vacuum yabandakanyeka ukususela kwinqanaba lokuqala leprojekthi yaza yasebenzisana ngokusondeleyo nomthengi ukuseka indlela yobugcisa. Uvavanyo lweesampulu, ukuqinisekiswa kokugquma, kunye nophuhliso lwenkqubo yokuvelisa ngobuninzi lwenziwe ngaxeshanye nobunjineli bezixhobo, okwenza inkqubo yokufaka kunye nomgca wemveliso ziguquke kunye.
Ekugqibeleni, omabini amaqela akhethe i-magnetron sputtering (PVD) njengetekhnoloji ephambili. Ifilimu efakweyo inika ukunamathela okuqinileyo kwi-substrate kwaye ivumela ukuba umaleko we-electrode yobhedu ufakwe ngqo kumphezulu we-ceramic ngaphandle kwe-organic binder esetyenziswa kwi-silver paste. Oku kususa imfuneko yezinyibilikisi kunye nokuphuma kwazo emanzini, ngelixa kususa inyathelo lokusila elinobushushu obuphezulu, okubangela inkqubo ecocekileyo neyomileyo enobuhlobo nokusingqongileyo xa kuthelekiswa nokusetyenzwa okumanzi okuqhelekileyo.
Ukuphucula ukusebenza kakuhle kokufakwa kunye nokuveliswa kwemveliso, iZhenhua yenze umgca wemveliso yokutshiza oqhubekayo onamacala amabini. Nje ukuba izinto zeseramikhi zingene kwinkqubo yokutshiza, omabini amacala anokugqunywa ngaphandle kokujikwa ngesandla, ngelixa ukudluliselwa kwezinto okuqhubekayo kudibanisa amanqanaba enkqubo nganye. Esi sisombululo senkqubo eyomileyo sithatha indawo yamanyathelo amaninzi enkqubo emanzi "yokuprinta ipeyinti yesilivere → ukomisa → ukutshiza," okwenza kube lula inkqubo iyonke ngelixa kuphucula ukuhambelana kwebhetshi ukuya kwibhetshi kunye nokusebenza kakuhle kwemveliso.
Ngowama-2012, izixhobo zaziswa ngempumelelo. Ukususela kwiingxoxo zokuqala zobugcisa kunye nophuhliso lwenkqubo ukuya ekuqalisweni nasekuphunyezweni komgca wemveliso, le projekthi ithathe malunga neminyaka emibini.
Ukuqinisekiswa Kwexesha Elide: Iminyaka Eli-14 Yokuveliswa Kobuninzi Okuqhubekayo
Ukusukela ngoSeptemba 2026, umgca wokutshiza oqhubekekayo omacala amabini owaziswa ngo-2012 usasebenza kwiziko lomthengi kwaye uxhasa imveliso yobuninzi ezinzileyo. Ngelixa ihlangabezana neemfuno zokufana kwengubo, ukuzenzekela kwenkqubo, kunye nokuveliswa komthamo ophezulu, isisombululo "sesilivere esithatha indawo yobhedu" sinciphisa kakhulu ukuxhomekeka kwisilivere yesinyithi esixabisekileyo kwaye sinciphisa iindleko zezinto ze-electrode, ngelixa sikwahambelana neemfuno zemveliso ecocekileyo nenoxanduva lokusingqongileyo. Emva kweminyaka eli-14 yokusebenza ngokuqhubekayo, izixhobo zibonelele ngokuqinisekiswa kwexesha elide kwesisombululo senkqubo kunye nezixhobo ngokubhekiselele ekusebenzeni kakuhle kweendleko, umgangatho wengubo, ukuthembeka kwemveliso, kunye nokuzinza kwemveliso yobuninzi.
Ngelo xesha, ishishini lasekhaya lalisekwinqanaba lokuqala lokuqonda nokwamkela indlela ye-copper-electrode, uninzi lwabavelisi luqhubeka nokuxhomekeka ekucutshungulweni kwe-silver paste. Nangona kunjalo, kwiminyaka yakutshanje, uxinzelelo olukhulayo lweendleko oluvela kwi-silver paste lukhawulezise utshintsho lweshishini oluya "kwi-copper replacement silver," okwenza izixhobo zokutshiza zibe sisisombululo esifunwa kakhulu kwimveliso ye-ceramic capacitor electrode. Ulwalathiso olufanayo lobuchwephesha luye lwavela ekuhloleni kwangaphambili ukuya ekugxileni kushishino olukhulu namhlanje—kunye neminyaka eli-14 yokuqinisekiswa kwemveliso phakathi.
Kumthengi, iingenelo bezihlala ixesha elide. Ukongeza ekunciphiseni ngokuthe ngqo iindleko zezinto eziphathekayo, inkqubo yemveliso iye yasusa ubuthathaka bayo ekutshintsheni kwamaxabiso esilivere kwiminyaka eli-14 ngaphambi kweshishini elikhulu. Umthengi ukwafumene ithuba lokuqala ekuthobeleni imimiselo yendalo kunye nokwenza izinto ngokuzenzekelayo. Nangona abavelisi abaninzi beqale ukujongana noxinzelelo olukhulayo oluvela kumaxabiso esilivere kunye nokuguqulwa kwenkqubo, lo mthengi sele egcine imveliso ezinzileyo ngetekhnoloji kangangeminyaka eli-14.
Le projekthi yayiyenye yeendlela zokuqala zokusetyenziswa kweteknoloji yokutshiza eqhubekayo emacaleni amabini kwimveliso ye-capacitor ye-ceramic ye-chip. Xa kujongwa imeko-bume yemizi-mveliso yasekhaya ngo-2012, ukuphunyezwa kwayo ngempumelelo kobunjineli kwabonisa impumelelo yokuqala ekuthengisweni kwetekhnoloji ye-copper-electrode. Yabonisa indlela ye-Zhenhua Vacuum ejonge phambili ekuphuhlisweni kwenkqubo kunye nokusasazwa kwetekhnoloji. Ngophuhliso lwezixhobo, ukuhanjiswa ngempumelelo, kunye neminyaka eli-14 yokuqinisekiswa kokuveliswa okuzinzileyo, le projekthi yaseka isikhundla esomeleleyo sokuqala se-Zhenhua Vacuum kwizicelo zokugquma i-capacitor ye-ceramic, ngelixa ibonelela ngamava axabisekileyo exesha elide ophuhliso lwezixhobo ezilandelayo, ukwenziwa ngcono kwenkqubo, kunye nokuphuculwa okuqhubekayo.
