摘要
锌片是化工行业的一种功能性金属粉体材料,呈鳞片粉末状,是通过对70-200μm的球形锌粉进行球磨、表面改性而制备的,具有较大的径厚比和超细超薄的特点,有良好的附着力、显著的防腐抗氧化效果、高强活性以及优良的导电性能,是生产水溶性无机盐涂料、无机富锌涂料、达克罗涂覆液的重要原料,在金属防腐领域具有球形锌粉无法比拟的优势。介绍了锌片项目的知识产权,制备技术,产品技术指标、技术水平以及锌片的应用领域和前景。
Flaky zinc powders are functional metal powder materials in chemical industry, which are prepared by ball-milling and surface modification of spherical zinc powders with diameters of 70-200 μm. In addition, zinc flakes are ultra-thin and ultra-fine powders with large diameter-thickness ratio, which possess good adhesion strength, remarkable effects of anti-corrosion and anti-oxidant, high activity and excellent conductivity. Zinc flakes are important raw materials for the production of water soluble inorganic salt coating, inorganic zinc-rich coating and dacromet coating. Compared with spherical zinc powders, zinc flakes have incomparable advantages in the field of metal anti-corrosion. The zinc flakes project′ s intellectual property rights, the preparation technologies, the technical indexes and technical level of products, as well as the application fields and prospects of zinc flakes are introduced.
