AI Technical Summary
The lack of effective methods in the prior art to prepare irregular columnar array zinc sheets makes it difficult to obtain this highly purified, non-toxic side effects, scientifically inspiring and artistically ornamental material.
By using zinc electrolyte containing 20 to 60 g/L of zinc, 120 to 190 g/L of sulfuric acid, and 5 to 40 mg/L of gelatin as the base liquid, and adding an appropriate amount of sodium silicate to the base, and electrolyzed by the traditional zinc electrolysis process, zinc sheets with irregular columnar arrays were prepared.
This method realizes irregular columnar array zinc sheets with simple process, low cost and large-scale production. The zinc sheets have high purity and no toxic side effects, and have rich three-dimensional structure and natural and smooth appearance.

Abstract
Description
Technical Field
[0001] The present application relates to the field of preparation of new metallurgical materials, and in particular to a method for preparing irregular columnar array zinc sheets. Background Art
[0002] The electrolytic irregular columnar array zinc sheet, on the one hand, has high purity, no toxic side effects, is easy to preserve in the air, has a rich, staggered three-dimensional structure, a natural and smooth morphology, and has certain scientific enlightenment and artistic appreciation; on the other hand, it can also be used as a template. When it is placed in a solution containing iron ions or copper ions, it can replace other metal models with irregular columnar arrays; in addition, it can also be used as a teaching aid for mass transfer models in replacement reactions (the irregular columnar top that is in full contact with the solution has a fast replacement reaction rate - more metal is replaced, while the root has a slow replacement reaction rate - less metal is replaced).
[0003] At present, there are few methods for preparing zinc sheets with irregular columnar arrays. Therefore, developing a new method for preparing zinc sheets with irregular columnar arrays has certain practical significance. Summary of the invention
[0004] The object of the present invention is to provide a method for preparing an irregular columnar array zinc sheet, which is specifically achieved through the following technical scheme.
[0005] A method for preparing an irregular columnar array zinc sheet, the steps of which are as follows:
[0006] A production zinc electrolyte containing 20-60 g / L zinc, 120-190 g / L sulfuric acid, and 5-40 mg / L gelatin is used as the base liquid, and 0.05-2 g of sodium silicate is added to each liter of the base liquid. After sufficient dissolution and mixing, the conventional zinc electrolysis process is used for electrolysis to prepare irregular columnar array zinc sheets.
[0007] The parameters of the conventional zinc electrolysis process are as follows: electrolyte temperature 37-44°C, cathode aluminum plate, anode lead-silver alloy plate, current density 300-600A / m 2 , the same inter-electrode distance is 5 to 7 cm, and the electrolysis cycle is 16 to 48 hours.
[0008] The beneficial effects of the present invention are as follows: the method has the advantages of simple process, low cost and large-scale production; the prepared zinc sheet has high purity, no toxic side effects, has a rich three-dimensional structure visible to the naked eye, and has a natural and smooth appearance.
