I-copper foil iyinsimbi encane kakhulu yethusi. Ingahlukaniswa ngenqubo ibe izinhlobo ezimbili: ucwecwe lwethusi olugoqiwe(RA) kanye necwecwe lethusi le-electrolytic(ED). I-copper foil ine-conductivity enhle kakhulu kagesi kanye ne-thermal, futhi inendawo yokuvikela amasignali kagesi kanye namagnetic. I-foil yethusi isetshenziswa ngobuningi ekwenzeni izingxenye ze-elekthronikhi ezinembayo. Ngokuthuthuka kokukhiqizwa kwesimanje, isidingo semikhiqizo ye-elekthronikhi emincane, elula, emincane futhi ephathwayo siholele ezinhlobonhlobo zezicelo zefoyili yethusi.
I-foil yethusi egoqiwe ibizwa ngokuthi i-RA ye-copper foil. Kuyimpahla yethusi eyenziwe ngokugoqa ngokomzimba. Ngenxa yenqubo yokukhiqiza, ucwecwe lwethusi lwe-RA lunesakhiwo esiyindilinga ngaphakathi. Futhi ingalungiswa ukuze ilulame futhi iqine ngokusebenzisa inqubo yokudonsa. I-RA ye-copper foil isetshenziswa ekwenzeni imikhiqizo ye-elekthronikhi ephezulu, ikakhulukazi leyo edinga izinga elithile lokuguquguquka kwezinto.
I-Electrolytic copper foil ibizwa ngokuthi i-ED copper foil. Kuyimpahla ye-copper foil eyenziwe ngenqubo yokubeka amakhemikhali. Ngenxa yemvelo yenqubo yokukhiqiza, i-electrolytic copper foil inesakhiwo sekholomu ngaphakathi. Inqubo yokukhiqiza ye-electrolytic copper foil ilula futhi isetshenziswa emikhiqizweni edinga inombolo enkulu yezinqubo ezilula, njengamabhodi wesifunda kanye nama-electrode e-lithium negative battery.
Ucwecwe lwethusi lwe-RA kanye necwecwe lethusi le-electrolytic linezinzuzo kanye nokungalungi kwazo kulezi zici ezilandelayo:
I-RA i-copper foil ihlanzekile ngokwezinto zethusi;
Ucwecwe lwethusi lwe-RA lusebenza kangcono kunabo bonke ucwecwe lwethusi lwe-electrolytic ngokwezakhiwo ezibonakalayo;
Kunomehluko omncane phakathi kwezinhlobo ezimbili zefoyili yethusi ngokwezakhiwo zamakhemikhali;
Mayelana nezindleko, ucwecwe lwethusi lwe-ED kulula ukulukhiqiza ngobuningi ngenxa yenqubo yalo yokukhiqiza olula futhi lubiza kancane kune-calendered copper foil.
Ngokuvamile, ucwecwe lwethusi lwe-RA lusetshenziswa ezigabeni zokuqala zokwenziwa komkhiqizo, kodwa njengoba inqubo yokukhiqiza ivuthwa kakhulu, ucwecwe lwethusi lwe-ED luzothatha izintambo ukuze kwehliswe izindleko.
I-copper foil ine-conductivity enhle kagesi kanye ne-thermal, futhi inezindawo ezinhle zokuvikela amasignali kagesi kanye namagnetic. Ngakho-ke, ivamise ukusetshenziswa njengendawo yokwenziwa kukagesi noma eshisayo emikhiqizweni ye-elekthronikhi nekagesi, noma njengento evikelayo kwezinye izingxenye ze-elekthronikhi. Ngenxa yezakhiwo ezibonakalayo nezingokomzimba ze-alloys zethusi nezethusi, nazo zisetshenziselwa ukuhlobisa izakhiwo nezinye izimboni.
Impahla eluhlaza ye-foil yethusi iyithusi elimsulwa, kodwa izinto zokusetshenziswa zisezifundeni ezihlukene ngenxa yezinqubo ezahlukene zokukhiqiza. Ucwecwe lwethusi olugoqiwe ngokuvamile lwenziwa ngamashidi ethusi e-electrolytic cathode ancibilika bese agoqwa; I-Electrolytic copper foil idinga ukufaka izinto ezingavuthiwe kusisombululo se-sulfuric acid ukuze incibilike njenge-copper-bath, bese ithambekele kakhulu ekusebenziseni izinto ezingavuthiwe ezifana ne-copper shot noma i-copper wire ukuze incibilike kangcono nge-sulfuric acid.
Ama-ion ethusi asebenza kakhulu emoyeni futhi angasabela kalula ngama-ion omoya-mpilo emoyeni ukuze akhe i-copper oxide. Siphatha ingaphezulu le-copper foil ngezinga lokushisa legumbi eliphikisana ne-oxidation phakathi nenqubo yokukhiqiza, kodwa lokhu kubambezela kuphela isikhathi lapho i-foil yethusi ikhishwa nge-oxidation. Ngakho-ke, kunconywa ukusebenzisa i-foil yethusi ngokushesha ngangokunokwenzeka ngemva kokukhipha. Futhi gcina ucwecwe lwethusi olungasetshenzisiwe endaweni eyomile, engenakukhanya kude namagesi aguquguqukayo. Izinga lokushisa elinconywayo lokugcina ucwecwe lwethusi lingaba ngu-25 degrees Celsius kanti umswakama akufanele udlule ku-70%.
I-copper foil ayiyona nje into eqhubayo, kodwa futhi iyimpahla yezimboni engabizi kakhulu etholakalayo. I-foil yethusi ine-conductivity kagesi kanye ne-thermal engcono kunezinto ezijwayelekile zensimbi.
Itheyiphu ye-foil ye-Copper ngokuvamile i-conductive ohlangothini lwethusi, futhi uhlangothi lokunamathisela lungenziwa futhi lube oluhambisayo ngokubeka i-powder conductive ku-adhesive. Ngakho-ke, udinga ukuqinisekisa ukuthi udinga itheyiphu ye-foil ye-copper conductive ohlangothini olulodwa noma i-double side conductive copper foil tape ngesikhathi sokuthenga.
I-foil yethusi ene-oxidation encane yendawo ingasuswa ngesipontshi sotshwala. Uma kuyi-oxidation yesikhathi eside noma i-oxidation yendawo enkulu, idinga ukususwa ngokuhlanza ngesisombululo se-sulfuric acid.
I-CIVEN Metal ine-copper foil tape eqondene ngqo nengilazi enemibala okulula kakhulu ukuyisebenzisa.
Ngokombono, yebo; nokho, njengoba ukuncibilika kwempahla akwenziwa endaweni engenalutho futhi abakhiqizi abahlukene basebenzisa amazinga okushisa ahlukahlukene kanye nezinqubo zokwakha, kuhlanganiswe nokwehluka kwezindawo zokukhiqiza, kuyenzeka ukuthi izakhi zokulandelela ezihlukene zixutshwe entweni ngesikhathi sokwenza. Ngenxa yalokho, ngisho noma ukwakheka kwezinto kuyafana, kungaba khona umehluko wemibala ezintweni ezivela kubakhiqizi abahlukene.
Ngezinye izikhathi, ngisho nasezintweni ze-foil zethusi ezihlanzekile, umbala ongaphezulu we-foil yethusi okhiqizwa abakhiqizi abahlukene ungahluka ebumnyameni. Abanye abantu bakholelwa ukuthi ama-foil ethusi amnyama anobumsulwa obuphakeme. Nokho, lokhu akulungile ngempela ngoba, ngaphezu kokuqukethwe kwethusi, ubushelelezi obungaphezulu becwecwe lethusi bungabangela nokwehluka kombala okubonwa iso lomuntu. Isibonelo, i-foil yethusi enobushelelezi obuphezulu izoba nokubukeka okungcono, okwenza umbala ongaphezulu ubonakale ulula, futhi ngezinye izikhathi ube mhlophe. Eqinisweni, lokhu kuyinto evamile ye-foil yethusi enobushelelezi obuhle, okubonisa ukuthi indawo engaphezulu ibushelelezi futhi inobulukhuni obuphansi.
I-Electrolytic copper foil ikhiqizwa kusetshenziswa indlela yamakhemikhali, ngakho-ke indawo yomkhiqizo oqediwe ayinawo uwoyela. Ngokuphambene, ucwecwe lwethusi olugoqiwe lukhiqizwa kusetshenziswa indlela yokugoqa ngokomzimba, futhi ngesikhathi sokukhiqiza, uwoyela wokugcoba ngomshini ovela kuma-roller ungahlala phezu nangaphakathi komkhiqizo oqediwe. Ngakho-ke, ukuhlanza ubuso obulandelayo kanye nezinqubo zokwehlisa amafutha kuyadingeka ukuze kukhishwe izinsalela zamafutha. Uma lezi zinsalela zingasuswa, zingathinta ukumelana ne-peel ebusweni bomkhiqizo ophelile. Ikakhulukazi ngesikhathi sokushisa okuphezulu kwe-lamination, izinsalela zamafutha zangaphakathi zingase zidlulele phezulu.
Lapho iphezulu ubushelelezi obungaphezulu be-foil yethusi, kuyanda ukubukeka, okungase kubonakale kumhlophe ngeso lenyama. Ubushelelezi obuphezulu bendawo bubuye buthuthukise kancane ukuhanjiswa kukagesi nokushisayo kwento. Uma inqubo yokugqoka iyadingeka kamuva, kuhle ukukhetha ukugqoka okusekelwe emanzini ngangokunokwenzeka. Izembatho ezisekelwe kuwoyela, ngenxa yokwakheka kwazo okukhulu kwamangqamuzana angaphezulu, cishe zizoxebuka.
Ngemuva kwenqubo yokuthungatha, ukuguquguquka okuphelele kanye ne-plasticity ye-copper foil material iyathuthukiswa, kuyilapho ukuphikiswa kwayo kuncishisiwe, kuthuthukisa ukuqhutshwa kwayo kagesi. Kodwa-ke, izinto ezifakwe emanzini zingenwa kalula imihuzuko namabombo uma zihlangana nezinto eziqinile. Ukwengeza, ukudlidliza okuncane ngesikhathi sokukhiqiza kanye nenqubo yokudlulisa kungabangela ukuthi impahla yonakale futhi ikhiqize ukugqama. Ngakho-ke, ukunakekelwa okwengeziwe kuyadingeka ngesikhathi sokukhiqiza nokucubungula okulandelayo.
Ngenxa yokuthi izindinganiso zamazwe ngamazwe zamanje azinazo izindlela zokuhlola ezinembile nezifanayo kanye namazinga ezinto ezinogqinsi olungaphansi kuka-0.2mm, kunzima ukusebenzisa amanani obulukhuni bendabuko ukuze kuchazwe isimo esithambile noma esiqinile sefoyili yethusi. Ngenxa yalesi simo, izinkampani ezikhiqiza ucwecwe lwekhopha zisebenzisa amandla aqinile kanye nobude ukuze zibonise isimo esithambile noma esiqinile sale nto, esikhundleni samanani wobulukhuni bendabuko.
