热镀(铝)锌板表面钝化现状与紫外光固化技术应用趋势的分析

Current Status of Surface Passivation in Hot-Dip Aluminum-Zinc Steel Plate and Analysis on the Application Trend of UV-Curable Technology

随着人们生活水平的不断提高,对环保的要求也越来越严格,热镀(铝)锌板因用传统方法热镀处理后处理液气味异常、环境污染严重,并且对人体危害大,因而其使用将受到严格的限制。而紫外光固化涂料作为一种环保涂料,近年来受到了涂料行业的广泛关注,本文通过对热镀(铝)锌版表面钝化现状的简要介绍和对紫外光固化技术的可行性分析,发现紫外光固化涂料具有固化速度快、固化程度高、室温固化、无溶剂配方等优点,能够在现有工艺系统中得到广泛使用。

With the continuous improvement of people’s living, the requirement standards for environmental protection are becoming more and more stringent. Due to the abnormal smell of the treatment solution after the traditional hot plating treatment, serious environmental pollution, and great harm to the human body, the use of hot-dip aluminum-zinc steel plate will be strictly restricted. As an environmentally friendly coating, UV-curable coatings have received extensive attention of the coating industries in recent years. Through a brief introduction to the current status of the surface passivation in hot-dip aluminum-zinc steel plate and analysis on the application tread of UV-curable technology, we have found that UV-curable coatings have the advantages of fast curing speed, high curing degree, room-temperature curing, solvent-free formulation. As a result, it can be widely used in the existing process system.
