Lub zog tensile σb thiab elongation δ tau kuaj los ntawm kev kuaj los ntawm cov ntawv txhuas tiav. Cov txheej txheem kuaj tau ua tiav ntawm WDW-10 hluav taws xob universal kuaj tshuab. Cov txheej txheem sim yog ua raws li cov kev cai cuam tshuam ntawm GB / T228-2002, tensile ceev yog 5.0mm / min, thiab tus nqi nruab nrab ntawm 3 cov qauv raug coj mus kuaj rau txhua tus nqi ntsuas; Qhov kev ntsuas lub zog tawg yog ua tiav ntawm BT-6 xuas nrig ntaus khob ntsuas tshuab raws li lub teb chaws tus qauv . Tshawb xyuas qhov loj thiab pes tsawg tus pinholes hauv cov ntawv txhuas tiav.

Tib lub sijhawm, coj mus kuaj los kuaj tus nqi dyne ntawm qhov chaw ntawm cov khoom tiav. Lub phaj zoo yuav tsum tiaj tus tsis muaj warping, thiab qhov dav yuav tsum ua tau raws li cov neeg siv khoom xav tau. Cov txiaj ntsig kev ua tau zoo thiab cov kev ntsuam xyuas saum npoo tau raug txheeb xyuas, thiaj li los soj ntsuam qhov zoo ntawm cov PTP aluminium ntawv ci substrate ua los ntawm kev siv cov cam khwb cia-dov billet, thiab thaum kawg txiav txim siab cov txheej txheem tsim khoom zoo tshaj plaws.

Cov khoom siv kho tshuab ntawm PTP aluminium foil substrate yuav tsum muaj σb siab dua 180Mpa thiab lub zog tawg ntawm ntau dua 300Kpa. Lub hom phiaj ntawm intermediate annealing yog tshem tawm kev ua hauj lwm hardening thiab sab hauv kev nyuaj siab thiab restore plasticity. Tib lub sijhawm, kub annealing tuaj yeem ua kom zoo dua cov nplej recrystallized ntawm kev lag luam ntshiab txhuas ntawv thiab strips, redistribute cov precipitated compounds, thiab muaj kev cuam tshuam tseem ceeb rau cov khoom siv kho tshuab ntawm cov khoom kawg.

Txawm li cas los, yog tias qhov kub ntawm annealing siab dhau lawm, cov nplej yuav coarsened. Los ntawm kev hloov cov txheej txheem annealing nyob rau hauv txoj kev npaj, uas yog, txo cov annealing kub los ntawm 480 rau 500 °C rau 450 rau 470 °C, lub zog tensile yog nce mus rau ntau tshaj 180Mpa. Hauv cov txheej txheem txheej txheem, Lub thickness thaum lub sij hawm nruab nrab annealing tau hloov ntawm 2.5mm mus rau 1.5mm. Los ntawm qhov pom ntawm kev ua tus nqi, nce tag nrho cov txheej txheem tom qab annealing tuaj yeem txhim kho lub zog tensile ntawm aluminium ntawv ci los ntawm kev ua haujlwm hardening. Txawm li cas los, nyob rau hauv cov txheej txheem ntau lawm, vim qhov nce hauv kev ua tiav thaum cov ntawv txhuas thiab ntawv ci dov, nws txhais tau hais tias kev ua haujlwm deformation nce. Txog 80% ntawm kev ua haujlwm deformation yuav hloov mus rau hauv deformation tshav kub, uas yog txaus kom cov ntawv ci ncav cuag qhov kub thiab txias. Lub sijhawm no, lub aluminium foil Hloov, nws softened.

Cov kev xav tau rau lub zog tensile ntawm cov ntawv ci tshuaj yog feem ntau hauv cov txheej txheem tsim khoom ntawm PTP aluminium ntawv ci, yog tias lub zog tsawg dhau, daim ntawv yuav tawg. Yog tias cov ntawv ci tawg yog nyob rau hauv lub qhov ziab kom qhuav, reconnection yog ib qho teeb meem ntau dua, yog li nws yuav muaj kev cuam tshuam ntau dua rau kev tsim khoom.

Txij li thaum cov tshuaj yuav txo cov kev ua tau zoo los yog deteriorate vim nkag mus ntawm oxygen, dej vapor thiab lub teeb, qhov yuav tsum tau rau lub pinhole degree ntawm PTP aluminium foil substrate yog qhov nruj. Muaj peb yam tseem ceeb uas cuam tshuam rau pinhole degree, metallurgical zoo, impurity cov ntsiab lus thiab compound loj. Kev txheeb cais qhia tau hais tias tus naj npawb ntawm pinholes hauv aluminium ntawv nyiaj nce nrog kev nce ntawm cov ntsiab lus suav nrog thiab qhov sib xyaw loj., thiab nce exponentially nrog lub thickness ntawm aluminium ntawv ci.

Lub metallurgical zoo thiab impurity cov ntsiab lus yog tswj los ntawm cov txheej txheem smelting thiab yaj purification ua ntej casting, thaum qhov loj ntawm cov tebchaw yog tswj los ntawm casting, txias dov thiab kev kho cua sov. Thaum qhov kub thiab txias tau qis dua, qhov loj ntawm tag nrho cov thawj crystal compound maj mam txo, cov ces kaum ntse tau yaj, tus naj npawb ntawm du thiab elongated tebchaw txo, thiab qib ntawm spheroidization tau nce ntau. Thaum PTP tshuaj foil hauv paus ntawv ci yog dov mus rau qee qhov tuab, qhov loj thiab tus naj npawb ntawm cov pinholes yuav txo qis raws li qhov txo qis ntawm qhov sib xyaw ua ke thiab qhov sib faib ntawm cov khoom sib xyaw.

Nyob rau hauv tus txheej txheem ntawm aluminium foil ntau lawm, ib tug loj npaum li cas ntawm cov roj lubricating yuav tsum tau siv kom txias thiab lubricate lub txhuas phaj. Cov txheej txheem muab khoom ntawm PTP tshuaj foil yog 8011 H18, thiab nws yog xa raws li tawv aluminium ntawv ci, yog li cov kev cai tswj cov roj nyob rau saum npoo ntawm aluminium ntawv ci yog nruj heev. Kev ntsuas qhov nro ntawm txhuas ntawv ci ua ntej tawm hauv lub Hoobkas yuav tsum ncav cuag 32 × 10-3N / m kom tau raws li qhov xav tau ntawm cov roj luam ntawv.

Cov txiaj ntsig tau pom tias cov khoom siv zoo PTP aluminium foil puag tuaj yeem tsim los ntawm kev siv 8011 aluminium alloy casting thiab dov billets, thiab nruab nrab annealing yog nqa tawm thaum nws txias dov mus rau 1.5 hli, thiab cov txheej txheem annealing yog 450 ~ 470 ℃ / 11 ~ 13h. Kev sib xyaw ua ke ntawm dov thiab ntawv ci dov txheej txheem tuaj yeem tau txais PTP aluminium foil substrates nrog cov khoom zoo thiab cov khoom siv kho tshuab..
