Waa sifada sanduuqa aluminiumka rogida in dhumucda dhumucda ay adagtahay in la xakameeyo. Farqiga dhumucda 3% ma adka in la xakameeyo wax soo saarka saxan iyo xariijimo, laakiin way adag tahay in la xakameeyo wax soo saarka aluminium foil.
Marka dhumucda sanduuqa aluminiumku uu noqdo mid khafiif ah, Xaaladihiisa yaryar ayaa saameyn kara, sida heerkulka, filim saliid, and oil and gas concentration. A roll of aluminum foil can be rolled up to hundreds of thousands of meters, and the rolling time is as long as about 10 saacadood, and the error of thickness measurement is easy to form with time.
The only way to adjust the thickness of aluminum foil is tension and speed.
These factors have caused difficulties in thickness control of aluminum foil rolling.
Sidaa darteed, to truly control the thickness difference of the aluminum box within 3%, many conditions are needed to ensure: use the aluminum foil blank of the qualified thickness; adjust and control the reduction and roll shape during rolling, and the roll is ground according to the specified parameters ; Stabilize the rolling process; frequently measure the thickness of the aluminum box during the rolling process, so as not to be undetected when the side thickness system fails.
