Copper foil chinhu chakaonda kwazvo chemhangura.Inogona kupatsanurwa nemaitiro mumhando mbiri: yakakungurutswa (RA) yemhangura foil uye electrolytic (ED) foil yemhangura.Copper foil ine yakanakisa magetsi uye yekupisa conductivity, uye ine midziyo yekudzivirira magetsi nemagineti masaini.Foil yemhangura inoshandiswa muhuwandu hukuru mukugadzirwa kwemaitiro emagetsi emagetsi.Nekufambira mberi kwekugadzirwa kwemazuva ano, kudiwa kwezvigadzirwa zvemagetsi zvakatetepa, zvakareruka, zvidiki uye zvinotakurika zvakakonzera kuwanda kwekushandiswa kwefoiri yemhangura.
Foil yemhangura yakakungurutswa inonzi RA copper foil.Icho chinhu chemhangura chinogadzirwa nekukunguruka kwemuviri.Nekuda kwemaitiro ayo ekugadzira, RA copper foil ine denderedzwa chimiro mukati.Uye inogona kugadziridzwa kune yakapfava uye yakaoma hasha nekushandisa annealing maitiro.RA copper foil inoshandiswa mukugadzirwa kwezvigadzirwa zvemagetsi zvemhando yepamusoro, kunyanya izvo zvinoda imwe dhigirii yekuchinjika muzvinyorwa.
Electrolytic copper foil inonzi ED copper foil.Iyo isimbi yemhangura foil inogadzirwa nekemikari deposition process.Nekuda kwechimiro chemaitiro ekugadzira, electrolytic copper foil ine columnar chimiro mukati.Maitiro ekugadzira e electrolytic copper foil ari nyore uye anoshandiswa muzvigadzirwa zvinoda huwandu hukuru hwemaitiro akareruka, senge mabhodhi edunhu uye lithium bhatiri negative electrodes.
RA copper foil uye electrolytic copper foil ine zvayakanakira nezvayakaipira mune zvinotevera zvinhu:
RA foil yemhangura yakachena maererano nemhangura yemukati;
RA copper foil ine zvirinani kuita kwese pane electrolytic copper foil maererano nehunhu hwemuviri;
Pane musiyano mudiki pakati pemhando mbiri dzemhangura foil maererano nemakemikari properties;
Panyaya yemutengo, ED copper foil iri nyore kugadzira yakawanda nekuda kwekuita kwayo kuri nyore kugadzira uye haina kudhura pane calendered copper foil.
Kazhinji, RA yemhangura foil inoshandiswa mumatanho ekutanga ekugadzirwa kwechigadzirwa, asi sezvo maitiro ekugadzira anowedzera kukura, ED copper foil ichatora nzvimbo kuitira kuderedza mutengo.
Copper foil ine yakanaka magetsi uye yekupisa conductivity, uye zvakare ine yakanaka yekudzivirira zvimiro zvemagetsi nemagineti masaini.Naizvozvo, inowanzo shandiswa sechisviniro chemagetsi kana chekupisa muzvigadzirwa zvemagetsi nemagetsi, kana sechinhu chinodzivirira kune zvimwe zvinhu zvemagetsi.Nekuda kwekuonekwa uye kwemuviri zvimiro zvemhangura nemhangura alloys, ivo vanoshandiswawo mukushongedza kwekuvaka uye mamwe maindasitiri.
Iyo yakasvibira yemhangura foil imhangura yakachena, asi zvigadzirwa zviri mumatunhu akasiyana nekuda kwemaitiro akasiyana ekugadzira.Foil yemhangura yakakungurutswa kazhinji inogadzirwa kubva kune electrolytic cathode mhangura mapepa anonyungudutswa obva akungurutswa;Electrolytic copper foil inoda kuisa mbishi mu sulfuric acid solution yekunyungudika semhangura-yekugezera, zvobva zvanyanya kuda kushandisa mbishi semhangura yekupfura kana waya yemhangura yekunyungudika zvirinani ne sulfuric acid.
Maoni emhangura anoshanda zvakanyanya mumhepo uye anogona kuita zviri nyore nemaoni eokisijeni ari mumhepo kuumba copper oxide.Isu tinobata pamusoro pefoiri yemhangura nekamuri tembiricha anti-oxidation panguva yekugadzira, asi izvi zvinongononotsa nguva iyo foil yemhangura inoiswa oxidation.Nokudaro, zvinokurudzirwa kushandisa foil yemhangura nokukurumidza sezvinobvira mushure mokusunungura.Uye chengetedza iyo foil yemhangura isingashandiswe munzvimbo yakaoma, isina chiedza-isingabvumirwe kure nemagasi anoputika.Iyo inokurudzirwa tembiricha yekuchengetera foil yemhangura ingangoita 25 degrees Celsius uye mwando haufanire kudarika 70%.
Copper foil haingori chinhu chinoitisa, asiwo inodhura-inoshanda maindasitiri zvinhu zviripo.Foil yemhangura ine zvirinani magetsi uye ekupisa conductivity pane zvakajairwa simbi zvinhu.
Mhangura foil tepi inowanzo fambisa padivi remhangura, uye divi rekunamira rinogonawo kuitwa conductive nekuisa conductive poda mune inonamira.Naizvozvo, iwe unofanirwa kusimbisa kana iwe uchida single-sided conductive copper foil tepi kana kaviri-sided conductive copper foil tepi panguva yekutenga.
Copper foil ine zvishoma pamusoro oxidation inogona kubviswa nedoro sponge.Kana iri nguva yakareba oxidation kana nzvimbo yakakura oxidation, inoda kubviswa nekuchenesa ne sulfuric acid solution.
CIVEN Metal ine tepi yemhangura foil yakanangana negirazi yakasvibiswa iri nyore kushandisa.
