Tuam Tshoj yog lub teb chaws uas muaj ntau tshaj plaws ntawm 6um-7um txhuas ntawv ci nyob rau hauv lub ntiaj teb no. Hauv 2009, nws tsim ntau tshaj 150kt ntawm txhuas ntawv ci nyob rau hauv no thickness ntau, ntawm uas ntau tshaj 70kt tau exported. Tam sim no, ntau tshaj 90% ntawm 6um-7um txhuas ntawv ci tsim nyob rau hauv kev lag luam hauv tsev yog ua los ntawm 1235 hlau alloy, thiab qee qhov chaw tsim khoom ntawm ob-zero foil tau pib siv 8079 hlau alloy, thaum European thiab Asmeskas kev lag luam feem ntau siv 8079 hlau alloy.

Cov tshuaj muaj pes tsawg leeg ntawm ?1235 hlau alloy thiab?8079 hlau alloy yog tib yam tshwj tsis yog cov ntsiab lus ntawm Fe element. Cov ntsiab lus ntawm Fe 1235 alloy yog 0.5-0.6, thaum ntawd 8079 alloy yog 0.85-0.95, thiab Si cov ntsiab lus ntawm ob qho tib si alloys yog 0.07-0.09.

Cov billets yog tsim los ntawm ingot kub dov. Ob lub alloys txais tib txoj kev ingot homogenization, thiab ces dov rau 1+4 kub dov khoom. Lub thickness ntawm cov khoom kub dov tiav yog 2.8mm-3mm.

Nyob rau hauv cov txheej txheem txias dov, nws yog dov mus rau ib tug tuab ntawm 0.28mm-0.30mm ib 3 hla, thiab tib cov txheej txheem annealing nruab nrab yog saws thaum dov mus rau lub thickness ntawm 0.5 hli, thiaj li thaum kawg tau lub thickness ntawm 0.28mm-0.30mm nyob rau hauv lub xeev H14. Aluminium ntawv ci khoom. Nyob rau hauv lub foil dov txheej txheem, Nws yog dov mus rau 0.015mm-0.017mm ib 3 hla, ces cov coils raug kaw, thiab qhov kub nruab nrab nruab nrab annealing yog ua, thiab cov txheej txheem qis-kub intermediate annealing yog tib yam.

Tom qab ntawd nqa tawm qhov kawg dhau ntawm dov mus rau cov khoom tiav tuab ntawm 0.006mm-0.007mm. Tom qab slitting rau cov khoom tiav specifications, qhov kawg khoom annealing yog nqa tawm, thiaj li thaum kawg tau ib tug degreased thiab huv si txhuas ntawv ci nyob rau hauv lub O lub xeev, thiab cov khoom kawg annealing txheej txheem ntawm ob alloys kuj yog tib yam.

(1) Rau 6um aluminium ntawv ci, qhov nruab nrab pinhole tus naj npawb ntawm 8079 alloy yog ho tsawg dua li ntawm 1235 hlau alloy; qhov nruab nrab tus naj npawb ntawm tawg xaus nyob rau hauv cov ntawv ci dov txheej txheem yog ho ntau dua li ntawm 1235 hlau alloy. Nyob rau hauv cov nqe lus ntawm Performance index, qhov nruab nrab tensile lub zog ntawm 8079 alloy yog ntau tshaj 10MPa siab tshaj li ntawm 1235 hlau alloy, thiab qhov elongation yog me ntsis siab dua li ntawm 1235 hlau alloy.

(2) Rau 7um aluminium ntawv ci, tus naj npawb ntawm pinholes ntawm 8079 alloy yog me ntsis ntau dua li ntawm 1235 hlau alloy, tab sis qhov sib txawv ntawm ob yog tsis pom tseeb; hos qhov nruab nrab tus naj npawb ntawm tawg xaus nyob rau hauv cov ntawv ci dov txheej txheem tseem yog li ntawd 8079 alloy yog siab dua li ntawm 1235 hlau alloy. Nyob rau hauv cov nqe lus ntawm Performance index, muaj tib yam tsis tu ncua li ntawm 6um txhuas ntawv ci.
Qhov sib txawv tseem ceeb ntawm 6um-7um txhuas ntawv ci tsim los ntawm 1235 alloy thiab 8079 alloy yog tias qhov Performance index ntawm 8079 alloy yog ho siab tshaj qhov ntawm 1235 hlau alloy, thiab tus naj npawb ntawm pinholes ntawm 6um txhuas ntawv ci tsim los ntawm 8079 alloy kuj tseem ceeb tsawg dua li ntawm 1235 hlau alloy.
