锌铝伪合金、金属铝和无机富锌涂装体系比较研究

Comparison and Study of Pseudo Zn-Al Alloy, Metal Aluminum and Inorganic Zinc-rich Coating Systems

我国已连续7a钢产量居世界之首,因此我国各项建设必然会纠正以前用混凝土代替钢材的局面。广泛地、正确地推广使用钢结构,必然会引起对钢结构防腐蚀的迫切关注。如何选用长效防腐蚀系统成为至关重要问题。现在在现有的典型防腐蚀系统的基础上发展出效果更好的喷"锌—铝伪合金"底层的长效防腐蚀系统。该文对锌-铝伪合金、金属铝、无机富锌涂装这三个系统作了对比研究。

The steel output of China has continuously placed the first of the world for 7a. Therefore, various constructions in China must correct the former phase of the concrete replacing the steel. Widely and exactly to spread the use of steel structure must bring the urgent attention for the corrosive resistance of steel structure. How to select the long-efficient anti-corrosive system becomes the important issue. Now the long-efficient anti-corrosive system to spray the better effect of'pseudo Zn-Al alloy'coating has been developed on the basis of the existing typical anti-corrosive system. The article contrasts and studies these three systems of pseudo Zn-Al alloy, metal aluminum and inorganic zinc-rich coating.
