I-foil yobhedu yinto enqabileyo kakhulu yobhedu.Inokwahlulwa ngokwenkqubo ibe ziindidi ezimbini: i-rolled (RA) ifoyile yobhedu kunye ne-electrolytic (ED) yobhedu yobhedu.I-foil ye-Copper ine-conductivity egqwesileyo yombane kunye ne-thermal, kwaye inepropati yokukhusela iimpawu zombane kunye nemagnethi.Ifoyile yobhedu isetyenziswa ngobuninzi xa kusenziwa izinto ezichanekileyo zombane.Ngenkqubela phambili yokwenziwa kwanamhlanje, imfuno yeemveliso ze-elektroniki ezincinci, ezikhaphukhaphu, ezincinci kunye eziphathwayo zikhokelele kuluhlu olubanzi lwezicelo zefoyile yobhedu.
Ifoyile yobhedu eqengqelekayo ibizwa ngokuba yiRA yobhedu.Yimpahla yobhedu eyenziwa ngokujikeleza ngokomzimba.Ngenxa yenkqubo yokwenziwa kwayo, ifoyile yobhedu yeRA inesakhiwo esingqukuva ngaphakathi.Kwaye inokulungelelaniswa kumsindo othambileyo kunye nobunzima ngokusebenzisa inkqubo ye-annealing.I-RA yobhedu ye-foil isetyenziselwa ukuveliswa kweemveliso ze-elektroniki eziphezulu, ngakumbi ezo zifuna iqondo elithile lokuguquguquka kwizinto eziphathekayo.
Ifoyile yobhedu ye-Electrolytic ibizwa ngokuba yi-ED copper foil.Yimpahla yefoyile yobhedu eyenziwa yinkqubo yokubeka imichiza.Ngenxa yobume benkqubo yokuvelisa, i-copper ye-electrolytic foil inesakhiwo sekholomu ngaphakathi.Inkqubo yokuvelisa i-electrolytic copper foil ilula kwaye isetyenziswa kwiimveliso ezifuna inani elikhulu leenkqubo ezilula, ezifana neebhodi zeesekethe kunye ne-lithium battery negative electrode.
Ifoyile yobhedu yeRA kunye nefoyile yobhedu ye-electrolytic ineengenelo kunye nokungalunganga kwezi zinto zilandelayo:
I-RA ye-copper foil ihlambulukile ngokubhekiselele kumxholo wobhedu;
I-RA ye-copper foil inomsebenzi ongcono jikelele kune-foil yobhedu ye-electrolytic ngokweempawu zomzimba;
Kukho umahluko omncinci phakathi kweentlobo ezimbini zefoyile yobhedu ngokweempawu zeekhemikhali;
Ngokwendleko, i-ED yefoyile yobhedu kulula ukuyivelisa ngobuninzi ngenxa yenkqubo yayo yokwenziwa ilula kwaye ayibizi kakhulu kune-calendered copper foil.
Ngokuqhelekileyo, i-RA ye-copper foil isetyenziswe kwizigaba zokuqala zokwenziwa kwemveliso, kodwa njengoko inkqubo yokuvelisa ikhula ngakumbi, i-ED ye-copper foil iya kuthatha ukuze kuncitshiswe iindleko.
Ifoyile yobhedu inombane kunye ne-thermal conductivity elungileyo, kwaye ineempawu ezintle zokukhusela imiqondiso yombane kunye nemagnethi.Ke ngoko, ihlala isetyenziswa njengento ephakathi kumbane okanye i-thermal conduction kwiimveliso zombane kunye nezombane, okanye njengesixhobo sokukhusela izinto ezithile zombane.Ngenxa yezinto ezibonakalayo kunye nezinto ezibonakalayo zobhedu kunye ne-alloys zethusi, nazo zisetyenziselwa ukuhlobisa izakhiwo kunye namanye amashishini.
Izinto ezikrwada zefoyile yobhedu lubhedu olusulungekileyo, kodwa izinto eziluhlaza zikwimeko ezahlukeneyo ngenxa yeenkqubo ezahlukeneyo zokuvelisa.Ifoyile yobhedu eqengqelekisiweyo ngokuqhelekileyo yenziwe kumaphepha obhedu e-electrolytic cathode anyibilikiswayo aze aqengqeleke;Ifoyile yobhedu ye-Electrolytic kufuneka ibeke imathiriyeli ekrwada kwisisombululo se-asidi ye-sulfuric ukuze inyibilike njengebhafu yobhedu, emva koko ityekele ngakumbi ekusebenziseni imathiriyeli ekrwada efana nokudutyulwa kobhedu okanye ucingo lobhedu ukunyibilika ngcono nge-asidi yesulfuric.
Iiyoni zobhedu zisebenza kakhulu emoyeni kwaye zinokusabela lula ngeeyoni zeoksijini ezisemoyeni zenze icopper oxide.Siphatha umphezulu we-copper foil kunye ne-anti-oxidation yegumbi lokushisa ngexesha lenkqubo yokuvelisa, kodwa oku kulibazisa kuphela ixesha apho i-foil yobhedu i-oxidation.Ngoko ke, kucetyiswa ukuba usebenzise i-foil yobhedu ngokukhawuleza emva kokukhupha.Kwaye gcina ifoyile yobhedu engasetyenziswanga kwindawo eyomileyo, engenakukhanya kude neegesi eziguqukayo.Ubushushu obucetyiswayo bokugcinwa kwefoyile yobhedu bumalunga nama-25 degrees celcius kwaye ukufuma akufuneki kudlule kwi-70%.
I-foil ye-Copper ayiyona nje into eqhubayo, kodwa kunye neyona nto ingabizi kakhulu kwimizi-mveliso ekhoyo.I-foil ye-Copper ine-conductivity engcono yombane kunye ne-thermal kunezixhobo eziqhelekileyo zetsimbi.
Iteyiphu ye-copper ye-copper iyaqhuba ngokubanzi kwicala lobhedu, kwaye icala lokuncamathela linokwenziwa liqhube ngokubeka umgubo wokuqhuba kwi-adhesive.Ke ngoko, kufuneka uqinisekise ukuba ufuna iteyiphu yefoyile yobhedu enecala elinye okanye icala eliphindwe kabini elinobhedu ngexesha lokuthenga.
I-foil yobhedu ene-oxidation encinci yendawo inokususwa ngesiponji sotywala.Ukuba i-oxidation ixesha elide okanye i-oxidation yendawo enkulu, kufuneka isuswe ngokucoca ngesisombululo se-sulfuric acid.
I-CIVEN Metal ine-tape ye-foil yobhedu ngokukodwa kwiglasi ecocekileyo ekulula kakhulu ukuyisebenzisa.
