8021 saj zawg zog ntim aluminium ntawv ci tam sim no muaj ntau yam teeb meem tseem tsis tau daws.
● Lub uniformity ntawm lub xeev nto ntawm 8021 saj zawg zog ntim aluminium ntawv nyiaj yog kim heev yuav tsum tau ib tug zoo nto, cov nqi ntau lawm yuav nce ntau, thiab txog tam sim no tsis muaj kev daws teeb meem zoo.
● 8021 txhuas ntawv ci raws li cov khoom tuab heev, uas siv yuav luag tag nrho nws cov plasticity. Lub reprocessability ntawm aluminium foil rau saj zawg zog ntim yog tsis siab, txawm siv cov tshiab alloys thiab cov txheej txheem, (xws li 8011, 8079). Plasticity tseem tsis yog txoj hauv kev zoo los txhim kho ntau yam. Cov txheej txheem ntim cov hnab ntim khoom siv tau yooj yim los txiav txim siab qhov no tsawg dua, yog li feem ntau qhov tshwm sim tawg.

● Kev ntsuas ntawm plasticity ntawm 8021 aluminium foil qhia tsis yog kev tshawb fawb, tsis tuaj yeem qhia qhov tseeb ntawm plasticity ntawm aluminium ntawv ci. Qhov kev ua tau zoo ntawm cov khoom ntim tau yooj yim aluminium foil tseem nyob rau theem sim. Yog tsis muaj kev ntsuas kev tshawb fawb los ntsuas, kev tshuaj xyuas ntau lawm tsis tuaj yeem ua tiav.
Kev xaiv ntawm cov tuab, tsim nyog txheej txheem laminating, cov ntaub ntawv sib txuam yog qhov tseem ceeb raws li kev ua haujlwm ntawm aluminium ntawv ci nws tus kheej. Kev sib txuam tsim nyog tuaj yeem tsis tsuas yog ua kom cov khoom zoo ruaj khov tab sis kuj txo tus nqi.
