Macro-molecular leakage-free self-adhering aluminum foil and manufacturing method thereof
A macro-molecular leakage-free self-adhering aluminum foil has two layers of aluminum foil compounded using a PET film, and the other surfaces of each layer coated with a modified PE adhesive layer respectively; or air gaps in one surface or two surfaces are filled with nano-aluminum to form a permeable air gap-free surface. The foil has advantages: 1, high folding resistance, fatigue resistance and strength 2, wrapping self-adhering performance is good, and stripping strength formed after adhesion is several times as high as that of the prior art; 3, air gaps in the surface of the aluminum foil filled with nano-aluminum powder result in improved compactness; manufacture from low-grade aluminum foil, and so that rolling precision requirements are lowered, and manufacturing cost reduced; 4, insulating strength is high, shielding effect is good, the return loss phenomenon is avoided, and tensile strength is good.
Systems and methods for controlling flatness of a metal substrate with low pressure rolling
A flatness control system includes a work stand of a finishing line, a plurality of actuators, a flatness measuring device, and a controller. The work stand includes a pair of vertically aligned work rolls. A first work roll of the pair of work rolls includes a plurality of flatness control zones configured to apply a localized pressure to a corresponding region on a substrate. Each actuator corresponds with a one of the plurality of flatness control zones. The flatness measuring device is configured to measure an actual flatness profile of the substrate. The controller is configured to adjust the plurality of actuators such that the localized pressures modify the actual flatness profile to achieve the desired flatness profile at the exit of the stand. The thickness and a length of the substrate remain substantially constant when the substrate exits the work stand.
