Aluminum Foil Roll A Grade Quslity
Aluminum Foil Roll A Grade Quslity According to the production status, there are two types of aluminum foil, soft and hard. Double zero foil is mostly used after softening and annealing
Double zero aluminum foil is relatively thin and is mainly used in the packaging industry, such as food packaging and cigarette packaging.
There are two types of aluminum foil, soft and hard according to the production state. Most of the double zero foils are used after softening annealing. The soft annealing is not only to control the mechanical properties of the aluminum foil, but also to eliminate the residual oil on the surface of the aluminum foil to obtain a smooth and bright surface. Unfold freely. Different aluminum foils require different levels of degreasing. For example, there must be no residual lubricating oil on the surface of composite aluminum foil and capacitor aluminum foil. But in recent years, users have put forward higher and higher requirements for the quality of double zero foil. The stickiness of aluminum foil has become one of the main defects. The sticky phenomenon of the double zero foil in the soft state is mainly manifested as: the touch of the double zero foil is "soft", and the user is not easy to maintain a flat shape during use; the double zero foil roll and layer In the process of uncoiling, it is difficult to peel off, causing the aluminum foil to not be used normally. Seriously affected the production and sales of aluminum foil.
However, the annealing process of our company has been improved. The main parameter of the annealing process is the annealing time, which mainly depends on the furnace load, the width of the foil coil and the coil diameter. The larger the furnace load, the larger the coil diameter and the wider the foil, the longer the annealing time. Under the premise of ensuring the degreasing effect, the lower the annealing temperature, the better, regardless of whether the aluminum foil is fully recrystallized. Satisfying user requirements is the basis for formulating new annealing.
Aluminum Foil Roll for Insulation The aluminum foil tape adopts pressure-sensitive adhesive, which has good texture and good anti-aging effect.
