Annealing Rolled Copper Foil: Kuvhura Kuwedzeredzwa Kwekuita kweMapurogiramu Epamusoro

Mumaindasitiri epamusoro-tekinoroji akadai sekugadzira zvemagetsi, simba rinogoneka, uye aerospace,yakakungurutswa yemhangura foilinokosheswa nekuita kwayo kwakanakisa, kusagadzika, uye nzvimbo yakatsetseka. Nekudaro, pasina kuvharirwa kwakaringana, foil yemhangura yakakungurutswa inogona kutambudzika nekuoma kwebasa uye kusara kunetseka, ichidzikamisa kushandiswa kwayo. Annealing inzira yakakosha inonatsa iyo microstructure yefoil yemhangura, inovandudza zvivakwa zvayo zvekukumbira zvikumbiro. Ichi chinyorwa chinotarisa mukati memisimboti yeannealing, maitiro ayo pakuita kwezvinhu, uye kukodzera kwayo kune akasiyana-ekupedzisira zvigadzirwa.

1. The Annealing Process: Kushandura Microstructure kune Superior Properties

Munguva yekukunguruka, makristasi emhangura anomanikidzwa uye akareba, achigadzira chimiro chefibrous chakazadzwa nekutsemuka uye kusara kunetseka. Iri basa rinoomesa rinoguma nekuwedzera kuoma, kuderedzwa ductility (kurebesa kwe3% -5 chete%), uye kuderera kudiki kwemaitiro kune anenge 98% IACS (International Annealed Copper Standard). Annealing inogadzirisa nyaya idzi kuburikidza neinodzorwa "kupisa-kubata-kutonhora" kutevedzana:

1. Kupisa Phase:Thefoil yemhangurainodziiswa kune yayo tembiricha recrystallization, kazhinji pakati pe200-300 ° C yemhangura yakachena, kumutsa kufamba kweatomu.
2. Kubata Phase: Kuchengetedza tembiricha iyi kwemaawa 2-4 kunobvumira zviyo zvakakanganiswa kuti zviore, uye zvitsva, zviyo zvakaenzana kuti zviumbe, nehukuru hunobva ku10-30μm.
3. Kutonhora Phase: Kunonoka kutonhora kwe ≤5 ° C / min kunodzivirira kuiswa kwezvitsva zvitsva.

Kutsigira Data:

• Annealing tembiricha inokanganisa zvakananga saizi yezviyo. Semuenzaniso, pa250 ° C, zviyo zvingangoita 15μm zvinowanikwa, zvichikonzera simba rekusimba re280 MPa. Kuwedzera tembiricha kusvika 300 ° C kunowedzera zviyo kusvika pa25μm, kuderedza simba kusvika 220 MPa.
• Nguva yekubata yakakodzera yakakosha. Pa280 ° C, 3-awa inobata inovimbisa pamusoro pe98% recrystallization, sezvakasimbiswa neX-ray diffraction analysis.

2. Advanced Annealing Equipment: Precision uye Oxidation Prevention

Kushanda annealing kunoda mavira akadzivirirwa gasi kuti ave nechokwadi chekugovera tembiricha yakafanana uye kudzivirira oxidation:

1. Furnace Design: Multi-zone yakazvimirira tembiricha yekudzora (semuenzaniso, nhanhatu-zone kumisikidzwa) inova nechokwadi chekusiyana kwetembiricha pahupamhi hwefoiri inoramba iri mukati me ± 1.5 ° C.
2. Inodzivirira Atmosphere: Kuunza high-purity nitrogen (≥99.999%) kana nitrogen-hydrogen mix (3% -5% H₂) inochengetedza mazinga eokisijeni pasi pe5 ppm, kudzivirira kuumbwa kwemhangura oxides (oxide layer thickness <10 nm).
3. Conveyance System: Tension-isina roller yekufambisa inochengetedza iyo foil flatness. Mavira epamusoro akatwasuka anogona kushanda nekumhanya kusvika 120 metres paminiti, aine simba rezuva nezuva rematani makumi maviri pachoto.

Nyaya Yokudzidza: Mutengi anoshandisa choto chisina-inert gasi chekumisikidza akawana reddish oxidation pafoil yemhangurapamusoro (okisijeni yemukati inosvika 50 ppm), inotungamira kune maburrs panguva yekucheka. Kushandura kune imwe nzvimbo yekudzivirira yevira yakakonzera kuoma kwepamusoro (Ra) ye ≤0.4μm uye yakagadziridzwa etching goho kusvika 99.6%.

3. Kuwedzera Kwekuita: Kubva ku "Industrial Raw Material" kuenda ku "Functional Material"

Annealed mhangura foilinoratidza kuvandudzwa kwakakosha:

Izvi zvinowedzera zvinogadzira annealed copper foil yakanakira:

1. Flexible Printed Circuits (FPCs): Nekurebesa pamusoro pe20%, iyo foil inomira pamusoro pe100,000 inoshanduka inopeta kutenderera, ichisangana nezvinodiwa zvezvishandiso zvinopeteka.
2. Lithium-Ion Battery Current Collectors: Mapepa akapfava (HV<90) anoramba kuputika panguva yekuputira electrode, uye ultra-thin 6μm mapepa anochengetedza uremu hunoenderana mukati me ± 3%.
3. High-Frequency Substrates: Kushata kwepasi pazasi 0.5μm kunoderedza kurasikirwa kwechiratidzo, kuderedza kurasikirwa kwekuisa ne15% pa28 GHz.
4. Electromagnetic Shielding Materials: Conductivity ye101% IACS inova nechokwadi chekudzivirira kushanda kweinenge 80 dB pa1 GHz.

4. CIVEN METAL: Pioneering Industry-Leading Annealing Technology

CIVEN METAL yakawana kufambira mberi kwakati wandei mu annealing tekinoroji:

1. Intelligent Temperature Control: Kushandisa PID algorithms ine infrared mhinduro, kuwana tembiricha kutonga chaiko kwe ± 1°C.
2. Enhanced Chisimbiso: Dual-layer furnace madziro ane dynamic pressure compensation inoderedza kushandiswa kwegasi ne30%.
3. Grain Orientation Control: Kuburikidza ne gradient annealing, ichigadzira mafoil ane kuomarara kwakasiyana-siyana pakureba kwawo, ane simba rakasiyana-siyana rinosvika 20%, akakodzera zvinhu zvakaoma zvakadhindwa.

Validation: CIVEN METAL's RTF-3 reverse-treated foil, post-annealing, yakasimbiswa nevatengi kuti ishandiswe mu5G base station PCBs, kuderedza dielectric kurasikirwa kusvika 0.0015 pa 10 GHz uye kuwedzera kutengesa kwekutengesa ne12%.

5. Mhedziso: Iyo Strategic Kukosha kweAnnealing muCopper Foil Production

Annealing inopfuura "kupisa-kutonhorera" maitiro; iko kubatanidzwa kwakaoma kwezvinhu zvesainzi uye engineering. Nekugadzirisa ma microstructural maficha akadai semiganho yezviyo uye dislocation,foil yemhangurashanduko kubva ku "basa-rakaomeswa" kuenda kune "inoshanda" nyika, ichitsigira kufambira mberi mu5G kutaurirana, mota dzemagetsi, uye inopfekeka tekinoroji. Sezvo maitiro ekuvhara achishanduka akananga kuhungwaru hukuru uye kuenderera mberi - senge CIVEN METAL kuvandudza kwehydrogen-powered furnaces kuderedza CO₂ emissions ne40% - yakakungurutswa yemhangura foil yakagadzirira kuvhura zvitsva zvinogona mukucheka-kumucheto maapplication.
