The Preparation Of Flake Zinc Powder And Its Research

Zinc chrome coating technology and DACRO technology, is a kind of process is simple and convenient, the protective effect of good surface coating technology. Widely used in automobiles, civil building, ships, Bridges, railways, subway, electrical appliances, etc. Flake zinc powder is DACROMET paint main raw material, the domestic research on DACROMET paint, this technology has digested and localization, but the research on flake zinc powder international level is quite big difference. Preparation of flake zinc powder widespread flake, have the degree of globular zinc powder, osteoporosis, surface can be large enough, quality defects. In the use of flake zinc powder, domestic most in use of DACROMET Coatings home is imported flake zinc powder. Therefore, the breakthrough of flake zinc powder, grasp the key technologies for reducing the production process of domestic DACROMET paint cost, promotion to replace electroplating, thus protecting the environment is of significance. This article mainly discusses on the preparation of flake zinc powder and performance.In this paper the preparation of flake zinc powder and research have been done, the main contents of the paper is as follows:(1) Use dry ball mill to prepare flake zinc powder, and carries on the characterization.(2) Single factor and orthogonal test preparation of flake zinc powder into the optimization of process.(3) In the process of exploring the products under optimal preparation, application of test, check product quality and performance.
