Copper foil yog dab tsi?
Copper foil yog hais txog ib qho tsis tshua muaj tooj liab strip los yog daim ntawv nrog lub thickness tsawg dua 200μm ua tiav los ntawm electrolysis thiab calendering, uas yog siv dav hauvhluav taws xob circuits, lithium-ionroj teebthiab lwm yam kev lag luam.
Cov ntawv ci tooj liab tuaj yeem muab faib ua ob hom raws li cov txheej txheem ntau lawm: electrolytic copper foil thiab dov tooj liab ntawv ci.
Electrolytic copper foil yog hais txog hlau tooj liab ntawv ci ua los ntawm electrolysis nrog cov khoom siv tooj liab ua cov khoom siv tseem ceeb.
Rolled tooj liab ntawv ci yog hais txog ib yam khoom ua los ntawm kev rov dov thiab annealing rau siab precision tooj liab sawb nrog lub hauv paus ntsiab lus ntawm cov yas ua.
Raws li daim ntawv thov sib txawv, nws tuaj yeem muab faib ua cov ntawv ci tooj liab rau lithium-ion roj teeb thiab cov ntawv ci tooj liab.
Copper foil rau lithium-ion roj teeb feem ntau yog siv los ua anode tam sim no sau ntawm lithium-ion roj teeb, thiab yog ib qho tseem ceeb ntawm cov qauv electrode.
Cov ntawv ci tooj liab yog txheej nyias ntawm cov ntawv ci tooj liab tso rau hauv qab txheej ntawm lub rooj tsav xwm hauv Circuit Court, uas yog ib qho tseem ceeb ntawm cov ntaub ntawv tseem ceeb ntawm tooj liab clad laminate (CCL) thiab luam tawm Circuit Board (PCB), thiab ua lub luag haujlwm ntawm tus neeg xyuas pib.
Copper foil rau lithium-ion roj teeb ua raws li tus neeg nqa khoom ntawm cov khoom siv anode, nrog rau cov khoom siv thiab cov neeg xyuas pib ntawm anode electron ntawm lithium roj teeb. Vim muaj kev ua tau zoo, kev ntxhib los mos, kev tsim technology, thiab tus nqi qis, nws tau dhau los ua cov khoom siv rau cov khoom siv tam sim no ntawm cov roj teeb lithium-ion.
Txawm li cas los xij, raws li cov tsoos anode tam sim no collector ntawm lithium-ion roj teeb, tooj liab ntawv ci muaj qee qhov teeb meem uas nyuaj los daws, nrog rau cov nqi tsim khoom siab thiab kev nyab xeeb kev nyab xeeb los ntawm cov khoom siv raw.
Yog li ntawd, txoj kev loj hlob tam sim no ntawm cov ntawv ci tooj liab yog qhov tseeb - kom nyias nyias thiab lub teeb nrog qhov ntom ntom. Yog tias cov ntawv ci tooj liab muaj cov tuab tuab, nws yuav muaj qhov hnyav dua ntawm nws qhov chaw nyob ib cheeb tsam, me me tsis kam, thiab roj teeb lub zog ntau dua.
Raws li lub thickness ntawm cov ntawv ci tooj liab siv rau lithium-ion roj teeb ua thinner, lub peev xwm tensile thiab tsis kam rau compressive deformation txo. Nyob rau hauv lwm yam lus, cov ntawv ci tooj liab yog ntau inclined rau tawg los yog tawg, uas yuav cuam tshuam rau kev nyab xeeb ntawm lithium-ion roj teeb. Tsis tas li ntawd, cov yam tseem ceeb xws li thickness uniformity, tensile zog, thiab nto wettability muaj kev cuam tshuam ncaj qha rau lub peev xwm, yield tus nqi, tsis kam, thiab kev pab cuam lub neej ntawm tooj liab ntawv ci. Yog li ntawd, lub thickness ntsuas ntawm tooj liab ntawv ci yog ib qho tseem ceeb txheej txheem ntawm tooj liab foil ntau lawm.
Raws li lub thickness ntawm tooj liab ntawv, nws yuav muab faib ua:
Thinner tooj liab ntawv ci (≤6μm)
Ultra-nyias tooj liab ntawv ci (6-12μm)
Nyias tooj liab ntawv ci (12-18μm)
Cov ntawv ci tooj liab tsis tu ncua (18-70μm)
Thick tooj liab ntawv ci (> 70μm)
X-ray on-line thickness (thaj tsamdensity) ntsuasgauge rautooj liab ntawv citsim los ntawm Dacheng Precision tuaj yeem siv rau kev tshuaj xyuas tuab ntawm cov ntawv ci tooj liab hauv lub cav tsis zoo thiab cov txheej txheem slitting. Nws qhov siab precision tuaj yeem pab kov yeej cov teeb meem ntawm kev ua haujlwm siab ultra-thin tooj liab ntawv ci.
Qhov zoo ntawm X-ray on-line thickness (thaj tsamdensity) ntsuasgauge rautooj liab ntawv ci
- Lub scanning ncej tuaj yeem kho raws li qhov loj me.
- Nws tuaj yeem ua tiav on-line Nrhiav tau ntawm Tooj Liab Sensity, thiab muaj cov haujlwm ntawm cov ntaub ntawv tiag tiag ua tiav kaw-voj nyaj. Nws tuaj yeem cuam tshuam qhov kev hloov pauv ntawm thaj chaw ceev, thiab tswj kev hloov pauv ntau ntawm +0.3um.
- Tus kheej-calibration system tshem tawm txhua yam cuam tshuam los ntawm kev ua haujlwm kom ruaj khov thiab raug ntawm kev ntsuas qhov system.
Lub kaw-voj system ntawm xoo hluav taws xob on-line thickness (gaure ceev) ntsuas ntsuas ntawm cov ntaub ntawv tuab lossis ua yeeb yaj kiab cov ntaub ntawv tuab, tswj hwm valve qhib. Lub kaw lus ntsuas tuaj yeem ntsuas qhov sib txawv ntawm txhua qhov ntsuas qhov ntsuas, tswj qhov ntws valve raws li PID tswj txoj cai, txhawm rau tswj qhov tuab lossis qhov ntom ntom.
