Cov txheej txheem txheej txheem aluminium foil feem ntau yog nyob ntawm kub dov. Txoj kev no ua ntej smelts raw aluminium rau hauv cov khoom loj, thiab tom qab ntawd sib xyaw ua kom sov thiab kub-yob rau hauv daim ntawv billets. Tom qab ntawd, los ntawm kev ntxhib dov, ua tiav dov thiab lwm cov kauj ruam, nws yog thaum kawg ua tiav rau hauv cov ntawv txhuas tiav. Txawm hais tias cov txheej txheem no tau siv dav, nws tseem muaj ntau qhov tsis txaus. Tag nrho cov txheej txheem ntau lawm yog cumbersome thiab koom nrog ntau cov txheej txheem, uas yog siv sij hawm thiab siv zog, ua rau muaj kev ua haujlwm tsawg. Tsis tas li ntawd, kev ntxhov siab loj deformation yog yooj yim tsim thaum lub sij hawm kub dov txheej txheem, uas cuam tshuam rau cov khoom zoo stability thiab cov khoom qauv uniformity. Vim yog tus nqi siab, qhov no kuj txwv kev tsim thiab nce qib ntawm ultra-nyias aluminium ntawv ci.
