Copper foil, iyi inoratidzika kunge yakapfava yekupedzisira-yakatetepa pepa remhangura, ine yakanyanya kutetepa uye yakaoma kugadzira maitiro.Kuita uku kunonyanya kusanganisira kucherwa nekunatswa kwemhangura, kugadzirwa kwefoiri yemhangura, uye matanho epashure pekugadzirisa.
Danho rekutanga kubviswa nekunatswa kwemhangura.Zvinoenderana nedata kubva kuUnited States Geological Survey (USGS), kugadzirwa kwepasi rose kwemhangura ore kwakasvika mamirioni makumi maviri ematani muna 20 (USGS, 2021).Mushure mekubviswa kwemhangura ore, kuburikidza nematanho senge kupwanya, kukuya, uye kutenderera, mhangura inonangana neinenge 30% yemhangura yemukati inogona kuwanikwa.Mhangura iyi inonangana yobva yaitwa nzira yekunatsa, kusanganisira kunyungudutswa, kushandurudza kukwenenzverwa, uye electrolysis, pakupedzisira ichiburitsa mhangura ye electrolytic nekuchena kwakakwira se99.99%.
Kunotevera kunouya nzira yekugadzira yemhangura foil, iyo inogona kukamurwa kuita mhando mbiri zvichienderana nekugadzira nzira: electrolytic copper foil uye yakakungurutswa foil yemhangura.
Electrolytic copper foil inogadzirwa kuburikidza ne electrolytic process.Musero re electrolytic, anode yemhangura inonyungudika zvishoma nezvishoma pasi pekuita kwe electrolyte, uye ayoni emhangura, inosundwa nezvino, inofamba ichienda kune cathode uye inoita madhipoziti emhangura pane cathode pamusoro.Ukobvu hwe electrolytic copper foil kazhinji hunobva pa5 kusvika ku200 micrometer, iyo inogona kunyatsodzorwa zvinoenderana nezvinodiwa zveakadhindwa redunhu board (PCB) tekinoroji (Yu, 1988).
Foil yemhangura yakakungurutswa, kune rumwe rutivi, inogadzirwa nemichina.Kutanga kubva papepa remhangura mamirimita anoverengeka gobvu, inoderedzwa zvishoma nezvishoma nekukunguruka, pakupedzisira ichigadzira foil yemhangura ine ukobvu pachiyero che micrometer (Coombs Jr., 2007).Mhando iyi yefoiri yemhangura ine nzvimbo yakatsetseka kupfuura electrolytic copper foil, asi maitiro ayo ekugadzira anopedza simba rakawanda.
Mushure mekugadzirwa kwemhangura yemhangura, inowanzoda kupinda mushure mekugadzirisa, kusanganisira annealing, kurapa kwepamusoro, nezvimwewo, kuti ivandudze kushanda kwayo.Semuyenzaniso, annealing inogona kuwedzera ductility uye kuoma kwefoiri yemhangura, nepo kurapwa kwepamusoro (senge oxidation kana coating) kunogona kukwidziridza kusaonda nekunamira kwefoiri yemhangura.
Muchidimbu, kunyangwe kugadzirwa uye kugadzirwa kwefoiri yemhangura kwakaoma, kuburitswa kwechigadzirwa kune chekuita zvakanyanya pahupenyu hwedu hwazvino.Uku kuratidzwa kwekufambira mberi kwetekinoroji, kushandura zviwanikwa zvechisikigo kuita zvigadzirwa zvemhando yepamusoro kuburikidza nehunyanzvi hwekugadzira.
Zvisinei, nzira yekugadzira foil yemhangura inounzawo mamwe matambudziko, kusanganisira kushandiswa kwesimba, kukanganisa kwezvakatipoteredza, nezvimwewo. Maererano neshumo, kugadzirwa kwe1 toni yemhangura kunoda anenge 220GJ yesimba, uye inogadzira 2.2 matani e carbon dioxide emissions (Northey). nevamwe, 2014).Nokudaro, tinofanira kutsvaga nzira dzakanyanyisa uye dzakapoteredza dzekugadzira foil yemhangura.
Imwe mhinduro inogona kushandiswa kushandisa mhangura yakadzokororwa kugadzira foil yemhangura.Zvinonzi kushandiswa kwesimba kwekugadzira mhangura yakadzokororwa inongova 20% yeiyo yekutanga mhangura, uye inoderedza kushandiswa kwemhangura ore zviwanikwa (UNEP, 2011).Pamusoro pezvo, nekufambira mberi kwetekinoroji, tinogona kugadzira nzira dzekugadzira mhangura dzemhangura dzinoshanda uye dzinochengetedza simba, zvichiwedzera kudzikisira kukanganisa kwadzo kwezvakatipoteredza.
Mukupedzisa, kugadzira uye kugadzira maitiro emhangura foil inzvimbo yetekinoroji izere nematambudziko nemikana.Kunyange zvazvo tafambira mberi zvikuru, kuchine basa rakawanda rinofanira kuitwa kuti tive nechokwadi chokuti foil yemhangura inogona kuzadzisa zvatinoda zuva nezuva tichichengetedza zvakatipoteredza.
