8011 Al Foil Roll Food Grade
Mos Temper Aluminium Ntawv Nyiaj RollsFeem ntau siv rau hauv cov khoom ntim vim tias lawv cov khoom zoo khaws cia, noo noo tsis kam thiab corrosion kuj.8011 Al Foil 10 Micronfeem ntau tsim ntau pinholes. Thaum txoj kab uas hla ntawm cov pinholes ntau dua 5 thiab nce mus txog 1, 000 ib square meter, nws yuav cuam tshuam ncaj qha rau qhov zoo ntawm lub ntim. Pinholes yog qhov taw qhia tseem ceeb ntawm qhov zoo ntawm aluminium ntawv ci thiab yuav tsum tau tswj nyob rau hauv ib tug tej yam ntau yam. GNEE siv cov tshuab ua haujlwm siab tshaj plaws los tsim cov kab ci ntsa iab yam tsis muaj pinholes.

The Fe and Si content in the aluminum foil material will directly affect the generation of pinholes. If Fe>2.5, A1 thiab Fe yuav yooj yim tsim coarse intermetallic tebchaw. Pinholes yuav yooj yim tshwm nyob rau hauv cov ntawv txhuas thaum dov. Raws li tus naj npawb ntawm Si nce, Fe thiab Si yuav cuam tshuam los tsim cov khoom sib xyaw.
The number of pinholes in the pure aluminum consumable material of grade 1060 will be far more than that of 1035 foil. This is due to the Fe and Si content in pure aluminum of grade 1035. Much higher than 1060. However, when the Ti content in the aluminum foil is >0.05, nws yog ib qho yooj yim los tsim ib qho nyuaj TiB2 compound, uas yog nkig thaum dov thiab tuaj yeem ua rau ntau lub pinholes.
Raws li tus thawj coj hauv kev lag luam txhuas, GNEE siv cov khoom lag luam ruaj khov, kev muag khoom thoob ntiaj teb thiab tus nqi tsim nyog raws li nws qhov kev sib tw tseem ceeb. Peb cov khoom tau siv dav hauv ntau tshaj 70 lub teb chaws thiab cheeb tsam suav nrog Tebchaws Meskas thiab European Union.
