As an important material in battery manufacturing, zinc plates for batteries have broad market prospects and development potential. By continuously optimizing the manufacturing process and improving product quality, the battery industry’s demand for high-performance, high-stability and environmentally friendly materials can be met.
Zinc is the second type of Fu group element in the periodic table. Its metallic state is silver-white. It is easily oxidized in air to form “white” (2ZnCo3.Zn(OH)2). Zinc is easily corroded in acid or lye.
The recrystallization temperature of zinc is very low, and blunt zinc (99.995%) can be carried out below 10″C, so that the processed zinc material is naturally annealed at room temperature, and the serious situation is easy to re-crystallize. Zinc has a temperature rise in the processing process. Trace impurities have a great influence on the properties of zinc.
(1) The alloy is hot rolled after casting, then cut into small pieces and rolled in the middle, and then in the finishing rolling will be multiple sheets of semi-finished rolled together, repeatedly through the roll, rolled into the final product.
(2) The castings are rolled in the same direction from the beginning of hot rolling, without cutting in the middle. Therefore, in the rolling process, the length of the zinc material will become longer and longer, and it needs to be rolled into a roll shape by the coiler. Because the coiler has a certain tension, the zinc strip is subjected to a certain tension during the rolling process, and sometimes a certain post-tension is also given before the material enters the roll, so that the material is subjected to tension before and after.
The basic process of both methods is the same, and the production process is as follows:
Ingredients (alloys)→Smelting (adding alloy)→Ingot casting→Hot Rolling→intermediate rolling→Finish rolling→Finished cutting→Inspection→packing
As a professional zinc plates manufacturer, IBC Group has been able to show through many years of practice that changes in organizational structure caused by changes in specifications during the process and their impact are far less than those caused by changes in composition. However, when the zinc plate composition is fixed, the battery made of a very uniform organization is indeed much superior to the corrosion resistance of an uneven organization.
At present, the zinc plate for dry battery is still improving from the composition to the processing method, and the quality is gradually improved. With the continuous expansion of the whole zinc cylinder, the stability of its quality is much greater than that of the zinc cylinder welded with zinc plate.
