Annealing Rolled Copper Foil: Gufungura imikorere Yongerewe Kumikorere Yambere

Mu nganda zikoranabuhanga cyane nko gukora ibikoresho bya elegitoroniki, ingufu zishobora kubaho, hamwe n’ikirere,umuringani ihebuje kubera ubwitonzi buhebuje, ubworoherane, n'ubuso bworoshye. Ariko, utabanje gufatana neza, umuringa uzengurutswe urashobora kubabazwa nakazi gakomeye hamwe nihungabana risigaye, bikagabanya imikoreshereze yacyo. Annealing ninzira ikomeye itunganya microstructure yaumuringa, kuzamura imitungo yayo yo gusaba porogaramu. Iyi ngingo iracengera mu mahame ya annealing, ingaruka zayo kumikorere yibintu, hamwe nuburyo bukwiye kubicuruzwa bitandukanye byo mu rwego rwo hejuru.

1. Inzira ya Annealing: Guhindura Microstructure kubintu byiza cyane

Mugihe cyo kuzunguruka, kristu y'umuringa irahagarikwa kandi ikaramburwa, igakora imiterere ya fibrous yuzuye dislokasiyo hamwe na stress isigaye. Uyu murimo ukomora ibisubizo bituma ubukana bwiyongera, kugabanuka guhindagurika (kurambura 3% -5% gusa), no kugabanuka gato kwimikorere igera kuri 98% IACS (International Annealed Copper Standard). Annealing ikemura ibyo bibazo ikoresheje "gushyushya-gufata-gukonjesha" ikurikiranwa:

1. Icyiciro cyo gushyushya:.umuringaashyutswe nubushyuhe bwayo, mubisanzwe hagati ya 200-300 ° C kumuringa usukuye, kugirango ukore atome.
2. Gufata Icyiciro: Kugumana ubu bushyuhe bwamasaha 2-4 bituma ibinyampeke bigoramye byangirika, kandi ibinyampeke bishya, bingana kugirango bibe, hamwe nubunini buri hagati ya 10-30 mm.
3. Icyiciro gikonje: Igipimo cyo gukonja gahoro cya ≤5 ° C / min birinda kwinjiza imihangayiko mishya.

Gushyigikira Amakuru:

• Ubushyuhe bwa Annealing bugira uruhare runini mubunini bw'ingano. Kurugero, kuri 250 ° C, ingano zingana na 15 mm ziragerwaho, bikavamo imbaraga zingana na 280 MPa. Kongera ubushyuhe kuri 300 ° C byongerera ingano kuri 25 mm, bikagabanya imbaraga kuri 220 MPa.
• Gufata umwanya ukwiye ni ngombwa. Kuri 280 ° C, gufata amasaha 3 bituma hejuru ya 98% byongera kugarurwa, nkuko byagaragajwe nisesengura rya X-ray.

2. Ibikoresho bigezweho bya Annealing: Kwirinda neza na Oxidation

Gufata neza bisaba itanura ryihariye ririnzwe na gaz kugirango harebwe ubushyuhe bumwe kandi birinde okiside:

1. Igishushanyo cy'itanura: Igice kinini cyigenga kugenzura ubushyuhe (urugero, ibice bitandatu bya zone) byemeza ko ubushyuhe butandukanye mubugari bwa foil buguma muri ± 1.5 ° C.
2. Ikirere gikingira.
3. Sisitemu yo Gutanga: Ubwikorezi bwa roller butagira impagarara bugumana uburinganire bwa file. Itanura rihanitse rya annealing itanura rishobora gukora ku muvuduko wa metero 120 kumunota, hamwe nubushobozi bwa buri munsi bwa toni 20 kuri buri ziko.

Inyigo: Umukiriya ukoresha itanura ya gaz itagira inert yahuye na okiside itukura kuriumuringahejuru (ogisijeni igera kuri 50 ppm), biganisha kuri burrs mugihe cyo kurira. Guhindukira ku itanura ryikirere gikingira byaviriyemo uburibwe (Ra) bwa ≤ 0.4 mm kandi byongera umusaruro wa etching kugera kuri 99,6%.

3. Kuzamura imikorere: Kuva "Inganda Zibikoresho Byinganda" kugeza "Ibikoresho Bikora"

Urupapuro rw'umuringayerekana iterambere ryinshi:

Ibi byongeweho bituma feza yumuringa ifata neza kuri:

1. Inzira zicapuwe zoroshye (FPCs): Hamwe no kuramba hejuru ya 20%, fayili ihangana ninzitizi zirenga 100.000 zigenda zunama, byujuje ibyifuzo byibikoresho bigendanwa.
2. Amashanyarazi ya Litiyumu-Ion: Impapuro zoroshye (HV <90) zirwanya gucikamo mugihe cyo gutwika electrode, kandi ultra-thin 6μm foil igumana uburemere muri ± 3%.
3. Ibihe Byinshi-Byinshi: Ubuso bwubuso buri munsi ya 0.5μm bugabanya gutakaza ibimenyetso, kugabanya igihombo cyo kwinjiza 15% kuri 28 GHz.
4. Ibikoresho bya Shitingi ya Electromagnetic: Imikorere ya 101% IACS itanga uburyo bwo gukingira byibuze 80 dB kuri 1 GHz.

CIVEN METAL yageze ku iterambere ryinshi mu buhanga bwa annealing:

1. Kugenzura Ubushyuhe Bwubwenge: Gukoresha PID algorithms hamwe nibitekerezo bitagira ingano, kugera kubushyuhe bwo kugenzura ubushyuhe bwa ± 1 ° C.
2. Ikidodo cyongerewe: Inkuta zibiri zikozwe hamwe nindishyi zingutu zigabanya gukoresha gaze 30%.
3. Kugenzura Ibinyampeke.

Kwemeza.

5. Umwanzuro: Akamaro k'ingamba za Annealing mu musaruro w'umuringa

Annealing ntabwo arenze "ubushyuhe-bukonje"; ni uburyo bukomeye bwo guhuza ibikoresho siyanse nubuhanga. Mugukoresha microstructural ibiranga nkimbibi zintete na dislocations,umuringainzibacyuho kuva "akazi gakomeye" ikajya muri "imikorere", ishimangira iterambere mu itumanaho rya 5G, ibinyabiziga byamashanyarazi, hamwe nikoranabuhanga ryambarwa. Mugihe ibikorwa bya annealing bigenda byiyongera mubwenge no kuramba - nko CIVEN METAL guteza imbere itanura rikoreshwa na hydrogène rigabanya imyuka ihumanya ikirere cya CO₂ ku kigero cya 40% - ifu yumuringa yateguwe yiteguye gufungura ubushobozi bushya mubikorwa byambere.
