Double zero aluminium foil sticky phenomenon

Double zero aluminium foil sticky phenomenon

Double zero foil is a foil with two zeros after the decimal point when its thickness is measured in mm, usually foil with a thickness of less than 0.0075 mm. Double-zero foils are sometimes sticky. The phenomenon of double-zero foil stickiness contains two layers of meaning, which we describe in detail next.

The mechanical properties of the aluminium foil do not meet the requirements of use and the surface of the aluminium foil is not well degreased, resulting in difficulties in peeling the aluminium foil during use. By improving the finished annealing process and controlling the amount of rolling oil and its physical and chemical properties in the rolling process, and by adjusting the tension parameters for slitting and slitting, the aluminium foil stickiness defect is eliminated. There are two types of aluminium foil according to the production state, soft and hard. Most of the double-zero foils are used after softening and annealing, which is not only to control the mechanical properties of the aluminium foil, but also to eliminate the residual oil on the surface of the foil, to obtain a flat and bright surface, and to be able to unfold freely. The degree of oil removal required differs for different uses of aluminium foil, e.g. aluminium foil for lamination and aluminium foil for capacitors must not have residual lubricating oil on the surface. In recent years, however, the quality of double-zero foil has become more and more demanding for users. Aluminum foil sticky become one of the main defects, soft state double zero foil sticky phenomenon is mainly manifested as: double zero foil feel "soft", the user is not easy to maintain a flat board type in the process; double zero foil volume layer and layer adhesion between, serious formation of "plate knot", in the unrolling process In the process of unrolling, it is difficult to peel off the foil, resulting in the foil not being used normally. This has a serious impact on the production and sale of aluminium foil.
