Yog vim li cas Electronic Aluminium Foil Demand yog nce
Electronic aluminium ntawv ci, tseem hu ua cov ntawv ci hluav taws xob lossis cov ntawv ci ci, yog tsim los ntawm siab -purity aluminium ingots los ntawm kev tswj ib ntus ntawm dov, tu thiab slitting. Nws yog qhov kev txiav txim siab raw khoom rau txhuas electrolytic capacitors, vim hais tias qhov etched nto ntawm cov ntawv ci txiav txim siab npaum li cas capacitance ib qho tuaj yeem xa tuaj. Kev thov rau cov khoom siv yog li ntawd taug qab lub khw muag khoom capacitor, thiab lub khw muag khoom capacitor taug qab cov hluav taws xob hluav taws xob: inverter, converters, hloov- hom khoom siv hluav taws xob, photovoltaic hlua inverters, roj teeb chargers, lub cev muaj zog tsav thiab DC - txuas theem ntawm cov tsheb fais fab.
Peb tus qauv tsav tsheb piav qhia txog kev loj hlob ruaj khov. Kev siv hluav taws xob ntxiv cov theem hloov pauv mus rau yuav luag txhua qhov system, thiab txhua theem xav tau ntau qhov peev xwm. Kev hloov pauv ntau dua thiab cov dej ntws ntau dua thawb cov neeg tsim qauv mus rau qis -ESR capacitor cov tsev neeg uas siv cov ntawv ci ntau dua rau ib chav tsev ntawm qhov muaj peev xwm. Miniaturization force capacitor makers yuav cov ntawv ci nrog thaj chaw siab dua etched thiab ntau lub zog zoo ib yam, ob qho tib si nyuaj rau tsim thiab yog li nqa tus nqi hwm.
Txoj kev tsim khoom los ntawm Ingot mus rau Capacitor Foil
Kev tsim khoom pib nrog siab -purity aluminium, ib txwm ua kom zoo li tsawg kawg 99.99 feem pua ntawm txhuas rau anode ntawv ci kom cov hlau seem, silicon thiab tooj liab tsis degrade anodic oxide txheej. Lub ingot yog kub dov rau slab, ces txias dov rau ntawm ib tug reversing zeb nrog dua passes, intermediate annealing thiab ntug trimming. Rolling oil thiab metallic nplua raug tshem tawm hauv ntau -theem tu kab ua ntej slitting rau qhov dav txiav txim.
Melt quality: siab -purity ingot nrog nruj tswj cov hlau, silicon thiab tooj liab cov ntsiab lus
Rolling: ntau-hloov txo qis mus rau qhov ntsuas kawg, nrog rau nruab nrab annealing los tswj cov nplej loj thiab kev ntxhib los mos
Ntxuav: degreasing thiab pickling kom tshem tawm cov roj dov, aluminium nplua thiab nto oxide
Slitting: dav, camber thiab ntug zoo matched rau automated winding kab
Etching thiab tsim: electrochemical etching ua raws li anodic re-oxidation uas tsim cov dielectric
Foil Hom thiab lawv cov Etched Structures
Cov qauv etch yuav tsum phim qhov ua haujlwm voltage ntawm lub capacitor. Tsawg-voltage thiab siab-voltage anodes yog etched nyob rau hauv txawv electrolyte chemistry, tam sim no ceev thiab waveform, thiab qhov tshwm sim geometry teeb tsa ob qho tib si capacitance nce thiab tiv taus voltage.
| Foil Hom | Lub luag haujlwm hauv Capacitor | Hom Etched Structure |
|---|---|---|
| High -voltage anode ntawv ci | Anode ntawm siab -voltage, loj- tuaj yeem ua tus capacitor | Qhov qhov-zoo li lossis ncej- zoo li lub qhov dej, ntxhib thiab tob, tso cai rau cov oxide tuab kom loj hlob yam tsis muaj kev puas tsuaj |
| Tsawg-voltage anode ntawv ci | Anode ntawm qis-voltage thiab nto-mount capacitor tsev neeg | Daim txhuam cev ntom ntom- zoo li cov qhov dej zoo uas ua kom thaj chaw loj tshaj plaws ntawm qhov tsim hluav taws xob tsawg |
| Nruab nrab-voltage anode ntawv ci | Anode rau nruab nrab voltage ntsuas | tawg, npauj -noj qhov qauv ntsuas qhov chaw nce tiv thaiv qhov muaj peev xwm |
| Cathode ntawv ci | Counter electrode ntawm winding element | Lub teeb etch los yog qhov chaw tiaj kom ua rau muaj kev tiv thaiv qis |
Corrosion foil yog cov khoom etched ua ntej tsim, thiab tsim cov ntawv ci, tseem hu ua chemical foil, yog cov khoom etched tom qab re-oxidation. Capacitor manufacturers uas khiav lawv tus kheej tsim kab yuav cov ntawv ci corrosion; cov uas outsource lub dielectric kauj ruam yuav tsim ntawv ci.
Dab tsi cov neeg yuav khoom yuav tsum txheeb xyuas ua ntej kev tsim nyog
Tshwj xeeb capacitance tom qab tsim, ntsuas ntawm tus neeg yuav khoom tus txheej txheem, tsis yog ntawm daim ntawv pov thawj tus neeg muag khoom nkaus xwb
Tensile lub zog thiab elongation nyob rau hauv qhov kev npau taws thiab ntsuas, vim hais tias tsis muaj zog foil kua muag ntawm siab -ceev winders
Thickness thiab dav kam rau ua, camber thiab burr qhov siab
Deg qib: dej stains, roj cim, khawb, pinholes, folds thiab ntug puas
Tsim qhov ntsuas hluav taws xob thiab kev coj tus cwj pwm ntawm cov ntawv ci tsim
Moisture -cov ntaub ntawv pov thawj, vim tias qhov chaw hydrated degrade etch thiab tsim cov txiaj ntsig
Kev sib pauv ntawm cov neeg muag khoom tsis yog qhov tsis tseem ceeb. Ob daim foils nrog cov qib nominal zoo ib yam thiab ntsuas ntsuas tseem tuaj yeem sib txawv hauv etch morphology thiab yog li ntawd nyob rau hauv capacitance thiab kev coj cwj pwm. Cov qauv tsim nyog yuav tsum tau khiav los ntawm tus neeg yuav khoom etching, tsim, winding thiab kev laus ua haujlwm ua ntej ntim tawm.
Cov qauv, Kev tshuaj xyuas thiab muab khoom Outlook
GB / T 3615 npog aluminium ntawv ci rau electrolytic capacitors thiab txhais cov tshuaj muaj pes tsawg leeg, qhov ntev, txhua yam khoom thiab qhov zoo ntawm qhov chaw, thaum GB / T 22638 series muab cov kev sim rau txhuas thiab aluminium ntawv ci. Capacitor- theem kev ua tau zoo yog tsim los ntawm IEC 60384 series rau cov khoom siv hluav taws xob ruaj khov rau siv hauv cov khoom siv hluav taws xob.
Kev tshuaj xyuas tuaj ib txwm sib txuas nrog daim ntawv pov thawj kev tshuaj xyuas nrog cov qauv rau cov tuab, dav, tensile zog, tshwj xeeb capacitance thiab pom qhov pom ntawm qib. Rau lub hom phiaj ntawm kev npaj, qhov kev txwv ntawm cov khoom siv tsis yog dov lub peev xwm tab sis tus naj npawb ntawm cov tsim nyog etching thiab tsim kab, uas yog vim li cas cov sij hawm txhuas rau siab -voltage anode foil yuav ncab ua ntej cov khoom ntim ntawv. Cov neeg yuav khoom nrog ntau- cov kev pab cuam xyoo yuav tsum khaws ob qhov chaw tsim nyog thiab pom zoo ntawm qhov muaj peev xwm-ib -square-meter specification es tsis yog lub ntsuas ntsuas -tsuas yog specification.
Cov lus nug nquag
Q: Dab tsi yog qhov txawv ntawm corrosion foil thiab formed foil?
Corrosion foil tau raug electrochemically etched kom loj nws qhov chaw zoo. Cov ntawv ci tsim tau ntxiv rau anodically re-oxidized, yog li cov txheej txheem aluminium oxide dielectric twb npog lub etched nto.
Q: Vim li cas 99.99 feem pua purity siv rau cov ntawv ci anode?
Residual hlau, silicon thiab tooj liab nce to tam sim no thiab tsis muaj zog anodic oxide. High purity nce lub peev xwm tawm los thiab qhov hluav taws xob tiv taus, txawm hais tias nws kuj nce nqi, yog li cathode foil tolerates qis purity.
Q: Yuav ua li cas yog foil thickness xaiv?
Thinner foil nce capacitance ib chav tsev ntim tab sis txo cov neeg kho tshuab lub zog thiab etched cheeb tsam tuav. High- cov qib hluav taws xob feem ntau yog tuab dua los txhawb cov qhov sib sib zog nqus thiab qhov tsim hluav taws xob ntau dua, thaum qis- cov qib voltage khiav nyias.
Q: Cov tsev neeg capacitor twg siv cov ntawv ci hluav taws xob ntau tshaj plaws?
High-voltage loj- tuaj yeem capacitors rau inverters thiab lub cev muaj zog tsav siv qhov loj tshaj plaws ntawm cov ntawv ci, ua raws li snap-hauv thiab ntsia hlau- hom davhlau ya nyob twg. Nto-mount tsev neeg siv me me tab sis siab dua - ntim qhov tsawg-voltage foil.
Q: Puas tuaj yeem tau txais ib daim ntawv foil hloov lwm qhov?
Tsuas yog tom qab cov txheej txheem tsim nyog. Etch morphology, tsim voltage thiab txhua yam khoom sib cuam tshuam, yog li nominal gauge match tsis tuaj yeem lav qhov kev sib tw lossis kev sib tsoo.
Q: Dab tsi ua rau stains thiab pinholes ntawm xa ntawv?
Moisture condensation nyob rau hauv ntim, residual dov roj, paug huv huv da dej thiab txhua yam kev sib cuag thaum slitting yog ib txwm ua. Qhuav, ntim ntim thiab ceev faj tuav tswj thaum lub sij hawm unwinding tiv thaiv lawv feem ntau.
