After special treatment, the 9-micron microporous aluminum foil with a pore structure is formed. Its main features include high specific surface area, high air permeability, good electrical conductivity and high mechanical properties.
The preparation method of 9 micron microporous aluminum foil is similar to the preparation method of ordinary microporous aluminum foil, and is usually prepared by electrochemical corrosion method or chemical corrosion method. However, preparing 9-micron microporous aluminum foil requires more precise process control and reaction conditions to ensure that the final product has the specified pore size, pore accuracy and uniformity.
Preparation by electrochemical corrosion method: This method has higher preparation cost and greater process difficulty, but it can produce products with smoother surfaces and uniform pore size distribution. In this process, it is crucial to strictly control the parameters of electrochemical corrosion.
Preparation by chemical etching method: This method is relatively low in preparation cost, but it requires strict control of process parameters during the preparation process to ensure the pore size and distribution uniformity of the product. In the preparation of chemical corrosion methods, accurate control of reaction conditions is particularly important.
