PET copper foil yog micron-scale composite tooj liab ntawv ci nrog "sandwich" qauv. PET copper foil yog cov ntawv ci tooj liab sib xyaw, uas muaj "sandwich" qauv ntawm "copper-polymer (PET)-copper" composite. Piv nrog rau cov ntawv ci tooj liab, tam sim no muaj plaub qhov zoo
Kev Nyab Xeeb: Hais txog kev nyab xeeb, cov txheej txheem ntawm cov ntawv sib xyaw tooj liab yog nyias thiab feem ntau yuav raug fused thaum muaj qhov luv luv hauv zos tshwm sim, ua rau lub zos tam sim no raug txiav tawm thiab txo cov cua sov uas tsim los ntawm luv luv Circuit Court.
Txhim kho roj teeb lub zog ceev: Qhov ceev ntawm PET polymer cov ntaub ntawv yog qhov qis dua ntawm tooj liab. PET copper foil siv PET los hloov qee cov khoom siv tooj liab hlau, yog li PET tooj liab ntawv ci yog qhov hnyav dua. Piv nrog rau cov ntawv ci tooj liab hauv kev lag luam, lub thickness ntawm cov ntaub ntawv tooj liab sib xyaw yog txo los ntawm 25%-40%, muab ntau qhov chaw rau cov khoom siv hauv lub roj teeb. Hauv cov roj teeb lithium, qhov txo qis ntawm qhov hnyav ntawm cov ntaub ntawv tooj liab sib xyaw thiab qhov nce ntawm qhov hnyav ntawm cov khoom siv tuaj yeem ua kom cov roj teeb lub zog ntom ntom ntawm 5% -10%.
Lub neej ntev: Raws li 2021 cov ntaub ntawv tshaj tawm txhua xyoo ntawm Dongwei Technology, lub voj voog lub neej ntawm lub roj teeb tuaj yeem nce 5% los ntawm kev siv cov ntawv ci tooj liab.
Tus nqi qis: Hauv ib txwm muaj lithium roj teeb tooj liab ntawv nyiaj, cov khoom siv ncaj qha suav rau feem ntau ntawm tag nrho cov nqi ntawm lithium roj teeb tooj liab ntawv ci, ncav cuag 83%. Kev siv PET tooj liab ntawv yuav txo tus nqi los ntawm 50%.
