PTP tshuaj txhuas ntawv ci tau dhau los ua ib qho ntawm cov ntaub ntawv tseem ceeb ntawm kev ntim tshuaj vim tias txhuas ntawv nyiaj tsis muaj tshuaj lom., tsw tsw, lub teeb nyob rau hauv qhov hnyav thiab muaj zoo shading zog, high noo noo kuj thiab barrier zog.

PTP aluminium ntawv ci substrates tuaj yeem muab faib ua tawv aluminium ntawv ci thiab mos aluminium ntawv ci. Cov qub feem ntau yog siv rau lub hlwv ntim ntawm cov tshuaj ntsiav tshuaj thiab tshuaj ntsiav, thaum lub sij hawm tom kawg yog feem ntau yog siv los ua cov ntim sab nrauv ntawm cov hmoov granules thiab hmoov rau cov tshuaj hauv cov ntim khoom sib xyaw. Nrog rau txoj kev loj hlob ntawm kev lag luam kws tshuaj, cov kev xav tau zoo rau cov tshuaj foils tau nce sai. Piv txwv li, raws li hom luam ntawv xim nce thiab hom xim sau npe nce, qhov zoo ntawm qhov yuav tsum tau muaj ntawm aluminium foils tau txais ntau dua thiab siab dua; nrog rau kev nce ceev ntawm gluing thiab cov khoom siv xim, Cov kev xav tau siab dua yog muab tso rau pem hauv ntej ntawm cov khoom siv kho tshuab ntawm aluminium foils; txhawm rau kom ntseeg tau tias cov khoom ntim tshuaj muaj kev nyab xeeb, txhawm rau tiv thaiv kev siv tshuaj tsis ua haujlwm lossis tsis zoo, thiab cov kev cai rau lub pinhole ntawm cov ntawv ci tshuaj tau dhau los ua nruj dua.

Cov khoom siv hauv paus ntawm PTP cov ntawv kho mob hauv tsev thiab txawv teb chaws yeej ib txwm siv cov ntshiab txhuas. Nws ntseeg tias qhov siab dua qhov purity, tsawg pinholes. Txog rau xyoo tas los no, 8 series aluminium alloys tau siv ntau dua thiab dav hauv PTP cov ntawv ci, feem ntau yog vim lawv cov khoom siv kho tshuab. Zoo, zoo heev pinhole yam ntxwv, roughness thiab gloss yog zoo dua li cov ntshiab aluminium ntawv ci, uas yog qhov zoo rau kev luam ntawv thiab kho kom zoo nkauj. Xws li 8011, 8021, 8079, lwm.

Daim ntawv no siv 8011 aluminium alloy raws li cov khoom tshawb fawb, siv nruam casting thiab dov billets los tsim 8011-H18 lub xeev cov ntawv nyiaj, thiab tsim ib tug series ntawm PTP tshuaj foil substrates nrog txawv thickness, kev ua haujlwm siab, siab flatness thiab zoo nto zoo. Tom qab raug tsim nyob rau hauv me me batch, tag nrho lawv ua tau raws li cov neeg siv khoom xav tau, thiab tam sim no lawv tau muab rau hauv cov khoom siv.

Lub cam khwb cia dov billet yog tsim los ntawm kab rov tav casting thiab dov zeb, thiab qhov luaj li cas ntawm cov cam khwb cia-dov billet yog 6.8 mm × 1280 mm × C, thiab nws cov tshuaj muaj pes tsawg leeg tau tswj raws li Table 1. Lub thickness ntawm cov ntawv ua tshuaj yog 0.02mm.
Raws li lub internal tswj muaj pes tsawg leeg ntawm 8011 alloy ntawv ci, aluminium ingot thiab master alloy yog alloyed thiab smelted nyob rau hauv lub qhov cub smelting, thiab aluminium alloy yaj yog degassed thiab impurity-refined nyob rau hauv lub qhov cub zoo li qub.

Los ntawm kev nruam hauv qab tshuab ntawm high-purity N2 thev naus laus zis hauv qab ntawm qhov cub, qhov tseeb tswj technology ntawm alloy muaj pes tsawg leeg, kev nruam online degassing ntawm yaj thiab ob-theem filtration technology, qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg ntawm aluminium yaj yog tswj nyob rau hauv 0.09%, thiab cov ntsiab lus hydrogen hauv cov yaj yog tswj tau. Hauv qab no 0.12 mL/kg, cov kev suav sau saum toj no 5 μm tau lim tawm, feem ntau ntawm cov roj thiab cov khoom siv hauv cov yaj raug tshem tawm, cov ntsiab lus ntawm impurity ntsiab raug txo, thiab lub hom phiaj ntawm kev txhim kho cov theem hlau faib thiab kev ua tiav ntawm cov cam khwb cia dov billet tau tiav.

Thaum casting, siv high-zoo Al-Ti-B hlau refiner, tswj qhov tsim nyog ntau yam ntawm casting thiab dov cheeb tsam thaum lub sij hawm casting thiab dov, nruj me ntsis tswj lub sab sauv txwv ntawm casting thiab dov ceev, thiab sim cam khwb cia raws li qhov tsawg kawg nkaus txwv ntawm pouring kub [5]. Nws tau ua kom ntseeg tau tias cov qauv qis-magnification ntawm cov cam khwb cia-dov aluminium billet yog me me thiab zoo ib yam, thiab cov nplej loj yog thawj-chav kawm equiaxed nplej. Thiab lub koom haum yog uniform, tsis muaj kev sib cais thiab lwm lub koom haum sab hauv.

Ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem txias dov thiab cov txheej txheem annealing ntawm PTP aluminium foil substrate.
Noj cov khoom ntawm 8011-H18 xeev thiab 0.020mm tuab cov ntawv ci ua piv txwv, cov txheej txheem ntws yog: Kev tshuaj ntsuam xyuas → txias dov → nruab nrab annealing → ntug trimming → ob dov → tiav cov khoom slitting → annealing → tshuaj xyuas, ntim, khaws cia .

Vim tias tus neeg siv tau nruj dua cov kev xav tau ntawm cov khoom siv kho mob ntawm cov ntawv ci tshuaj, thiab cov kev xav tau siab dua ntawm qhov zoo, Nws yuav tsum tau hais tias cov roj yuav tsum huv si thiab tus nqi deg dyne yuav tsum yog saum toj no 32 × 10-3N / m. Cov ntawv 6.8mm tuab cam khwb cia-dov tau txias-kub rau 2.5mm thiab 1.5mm, raws, thiab raug rau nruab nrab annealing nyob rau hauv txawv systems. Tom qab trimming, ob-coated ntawv ci tau dov mus rau ib qho khoom tiav ntawm 0.02mm.
