Cov capacitors ceramic yog cov khoom siv hluav taws xob uas siv cov khoom siv ceramic ua cov dielectric thiab cov hlau electrodes los khaws cov nqi hluav taws xob. Lawv siv dav hauv cov khoom siv hluav taws xob, kev sib txuas lus, cov khoom siv hluav taws xob hauv tsheb, thiab cov ntawv thov tswj kev lag luam, qhov twg lawv ua cov haujlwm tseem ceeb xws li decoupling, filtering, coupling, resonance, thiab energy storage.
Yuav kom khaws tau cov nqi hluav taws xob thiab tsim kom muaj kev sib txuas hluav taws xob nrog cov voj voog sab nraud, cov electrodes yog ib feem tseem ceeb ntawm cov qauv capacitor. Cov electrodes hlau tau muab faib rau ob sab ntawm cov ceramic dielectric lossis hloov pauv nrog cov txheej dielectric hauv cov qauv ntau txheej, ua ke tsim cov qauv capacitor yooj yim. Thaum muaj hluav taws xob, cov nqi hluav taws xob sib sau ua ke ntawm ob lub electrodes thiab txuas nrog lub voj voog sab nraud los ntawm cov qauv electrode.
1. Vim li cas tus nqi ntawm Cov Hluav Taws Xob Nyiaj-Paste rau Cov Capacitors Ceramic thiaj li tseem nce ntxiv?
Cov txheej txheem tsim cov electrode ib txwm muaj rau cov capacitors ceramic feem ntau siv cov txheej txheem luam ntawv thiab tua hluav taws xob. Cov txheej txheem feem ntau muaj kev npaj cov khoom siv ceramic, luam ntawv nyiaj, ziab, tua hluav taws kub siab, tshuaj xyuas electrode, thiab kev ua tiav tom qab. Cov thev naus laus zis no tau siv dav rau ntau xyoo, nrog rau cov qauv tshuaj pleev xim nyiaj laus, cov thev naus laus zis luam ntawv, cov txheej txheem luam ntawv, thiab cov txheej txheem tua hluav taws. Nws cov khoom siv tsim khoom thiab cov khoom siv txhawb nqa tau tsim zoo, nrog rau qhov tsis tshua muaj teeb meem rau kev siv cov kab ntau lawm thiab kev hloov pauv zoo rau cov khoom nrog cov lus qhia sib txawv.
Tib lub sijhawm, cov tshuaj nplaum nyiaj siv cov hmoov nyiaj ua nws cov khoom tseem ceeb thiab tsim cov electrode los ntawm cov txheej txheem tuab. Yog li ntawd, cov txheej nyiaj tuab dua, ua rau muaj kev siv nyiaj ntau dua rau ib yam khoom.
Thaum tus nqi nyiaj qis dua, qhov cuam tshuam ntawm tus nqi uas cuam tshuam nrog kev siv nyiaj ntau tsis tseem ceeb. Txawm li cas los xij, vim tias tus nqi nyiaj tau txuas ntxiv nce siab mus ntev, cov qauv nqi no tau pom tseeb dua. Raws li tus nqi nyiaj nruab nrab txhua xyoo hloov mus rau hauv RMB, tus nqi ntawm cov nyiaj yog kwv yees li RMB 1.9 / g hauv xyoo 2005, piv rau kwv yees li RMB 9.2 / g hauv xyoo 2025, sawv cev rau kev nce ntxiv ntawm kwv yees li 4.8 npaug dhau 20 xyoo.
Rau cov chaw tsim khoom siv capacitor ceramic uas muaj ntau, qhov cuam tshuam ntawm tus nqi nyiaj nce siab zuj zus thaum cov khoom tsim tawm loj hlob tuaj. Kev siv nyiaj ntau dua ib chav, muab ntau dua los ntawm cov khoom tsim tawm txhua xyoo ntawm lab, kaum tawm lab, lossis ntau dua, tuaj yeem txhais ua cov nqi khoom siv tag nrho. Thaum tus nqi nyiaj tseem nyob ntawm qib siab, cov txheej txheem electrode nyiaj-paste ib txwm muaj thiab tau tsim zoo ntsib kev nyuaj siab ntau ntxiv los ntawm cov nqi hlau muaj nqis.
Nyob rau hauv qhov teeb meem no, txo kev siv nyiaj thiab txo kev vam khom rau cov hlau muaj nqis thiab lawv cov nqi hloov pauv tau dhau los ua qhov tseem ceeb rau cov chaw tsim khoom siv capacitor ceramic.
2. Zhenhua Vacuum Txoj Kev Txo Nqi: Los ntawm "Tooj Liab Hloov Nyiaj" mus rau Kev Tsim Khoom Loj tas mus li
Vim yog kev siv cov hlau muaj nqis ntau, ntau kauj ruam ntawm cov txheej txheem, thiab kev raug rau kev hloov pauv ntawm tus nqi nyiaj uas cuam tshuam nrog cov electrodes nyiaj-paste ib txwm muaj, Zhenhua Vacuum tau tshawb nrhiav txoj hauv kev siv magnetron sputtering-based "tooj liab hloov nyiaj" rau cov electrodes ceramic capacitor thiab tau nrhiav kev txo tus nqi los ntawm kev ua kom zoo dua qub thiab kev hloov khoom siv.
Es tsis txhob cia siab rau kev tsim cov electrode uas muaj cov nyiaj nplaum ib txwm muaj, Zhenhua Vacuum siv cov thev naus laus zis magnetron sputtering. Raws li cov txheej txheem physical vapor deposition (PVD), magnetron sputtering tso cov khoom siv hlau ncaj qha rau ntawm qhov chaw ntawm cov khoom siv ceramic hauv qhov chaw nqus tsev kom tsim cov zaj duab xis electrode.
Piv nrog rau kev luam ntawv siv nyiaj nplaum, cov txheej txheem no tshem tawm ntau kauj ruam ib txwm muaj, suav nrog kev npaj nyiaj nplaum, kev luam ntawv, kev ziab, thiab kev hlawv kub siab, yog li ua rau cov txheej txheem luv luv thiab txo cov kev tuav thiab kev ua haujlwm tes. Vim tias cov nyiaj nplaum thiab nws cov organic binders thiab cov neeg nqa khoom tsis tas yuav tsum muaj, cov txheej txheem kuj tseem tuaj yeem txo cov pa phem organic thiab cov txheej txheem pov tseg uas cuam tshuam nrog kev tsim cov electrode raws li nplaum, muab lub peev xwm ntau dua rau kev tsim khoom huv dua thiab ntau dua.
Los ntawm qhov pom ntawm cov khoom siv, tooj liab yog siv ua cov khoom siv hluav taws xob tseem ceeb los hloov nyiaj. Tooj liab muaj kev coj hluav taws xob zoo heev thaum nws cov nqi khoom siv qis dua li nyiaj. Qhov no ua rau muaj kev txo qis ntawm kev siv hlau muaj nqis ntawm cov khoom siv. Rau kev tsim khoom ntau, kev hloov pauv khoom siv no tuaj yeem txo cov nqi khoom siv hluav taws xob thaum txo qis qhov cuam tshuam ntawm kev hloov pauv ntawm tus nqi nyiaj rau tag nrho cov nqi tsim khoom.
Txawm li cas los xij, kev hloov nyiaj nrog tooj liab tsis yog ib qho teeb meem ntawm kev hloov ib qho khoom siv electrode mus rau lwm qhov. Tooj liab yog qhov yooj yim rau oxidation ntawm qhov kub siab, thiab cov txheej txheem luam ntawv thiab hlawv tooj liab ib txwm xav tau kev tswj hwm nruj ntawm cov qauv nplaum, cua hlawv, thiab qhov rai txheej txheem. Magnetron sputtering, los ntawm qhov sib piv, ua rau cov yeeb yaj kiab tooj liab raug tso ncaj qha rau hauv qhov chaw nqus tsev. Los ntawm kev tsim cov txheej txheem nplaum, cov txheej txheem conductive, thiab lwm cov txheej txheem ua haujlwm, cov txheej txheem tuaj yeem txhim kho cov yeeb yaj kiab nplaum, qhov ceev, thiab kev ua haujlwm hluav taws xob, muab lwm txoj hauv kev rau kev siv kev lag luam ntawm "tooj liab hloov nyiaj."
2.1 Txij li Kev Txhim Kho Txheej Txheem mus rau Kev Tsim Khoom Loj: Zhenhua Vacuum's Double-Sided Continuous Magnetron Sputtering Production Line
Magnetron sputtering tuaj yeem muab txoj hauv kev rau "tooj liab hloov nyiaj," tab sis rau kev tsim cov capacitor ceramic ntau ntau, kev tsim cov qauv coated ib leeg tsis txaus. Qhov kev sib tw tseem ceeb yog ua tiav kev tsim khoom loj mus sij hawm ntev, ruaj khov, thiab txuas ntxiv mus.
Yuav kom daws tau qhov teeb meem no, Zhenhua Vacuum tau tsim ib txoj kab ntau lawm magnetron sputtering ob sab rau cov electrodes ceramic capacitor, uas sib xyaw cov thev naus laus zis nqus tsev nrog kev tsim khoom tsis siv neeg. Tom qab nkag mus rau hauv txoj kab ntau lawm, cov khoom raug xa mus tas li ntawm cov chav ua haujlwm sib txawv, thaum cov yeeb yaj kiab electrode raug tso rau ob sab hauv tib lub tshuab tsim khoom. Qhov no txo qhov xav tau kev tig tes, kev thauj khoom thiab tshem tawm ntau zaus, thiab kev tuav nruab nrab ntawm cov txheej txheem.
Cov khoom siv no siv cov kab ntau lawm uas txuas ntxiv mus tas li, ua rau cov txheej zaj duab xis sib txawv, suav nrog cov txheej nplaum lossis cov txheej hloov pauv thiab cov txheej hluav taws xob, kom muab tso rau hauv tib lub kaw lus sib xyaw. Los ntawm kev hloov cov khoom siv tsis siv neeg, kev tswj cov txheej txheem kom meej, thiab kev tswj hwm cov txheej txheem ntau lawm, lub kaw lus no txhim kho qhov tuab ntawm zaj duab xis thiab kev ruaj khov ntawm cov txheej txheem thaum lub sijhawm tsim khoom ntau.
Txoj kev ua no kuj tau dhau los ua qhov kev txheeb xyuas ntev hauv kev tsim khoom loj. Xyoo 2012, Zhenhua Vacuum tau xa cov kab ntau lawm magnetron sputtering ob sab rau cov electrodes capacitor ceramic rau tus neeg siv khoom. Txij li xyoo 2026, cov kab ntau lawm tau nyob ruaj khov rau 14 xyoos, muab kev txheeb xyuas ntev ntawm kev ntseeg tau ntawm cov khoom siv, kev sib xws ntawm cov txheej txheem ob sab, thiab kev ua tau ntawm cov txheej txheem magnetron sputtering "tooj liab hloov nyiaj".
Kev hloov pauv ntawm cov electrodes nyiaj-paste ib txwm mus rau magnetron sputtering-based "tooj liab hloov nyiaj" tsis yog tsuas yog hloov cov khoom siv xwb. Nws sawv cev rau kev ua kom zoo dua ntawm cov ntaub ntawv, cov txheej txheem tso tawm, thiab cov txheej txheem tsim khoom. Los ntawm kev siv tshuab magnetron sputtering thiab cov kab ntau lawm ob sab, Zhenhua Vacuum tau coj lub tswv yim "tooj liab hloov nyiaj" dhau ntawm kev daws teeb meem kev siv tshuab thiab mus rau hauv kev tsim khoom loj, ruaj khov thiab txuas ntxiv mus.
Rau kev tsim cov capacitor ceramic ntau, tus nqi kev lag luam ntawm "tooj liab hloov nyiaj" tsuas yog tuaj yeem paub tag nrho thaum cov nqi khoom siv raug txo qis, cov txheej txheem tsim khoom raug ua kom yooj yim, thiab kev ruaj khov ntawm kev tsim khoom mus sij hawm ntev tau ua tiav tib lub sijhawm.
