Steel structure faces anti-corrosion problems in bridge construction
With the development of social economy, China's transportation industry continues to progress, and bridge construction is an important part of the transportation industry. In the construction of bridge construction, steel structure actively exerts its advantages in bridge design and application. It has the advantages of high strength, convenient installation, short construction time, and strong load capacity. It has been widely used in railways, highways, and road-rail dual-use bridges. And pedestrian bridges.
However, the steel structure in the atmospheric environment is affected by sunlight, sand, rain, snow, frost, and changes in temperature and humidity throughout the year, and its anti-corrosion problem has attracted much attention. Especially in coastal areas where there are long-term cold and hot, dry and wet alternates, the corrosion of steel is accelerated and the service life of bridges is shortened. Therefore, it is particularly important to design a long-term corrosion protection and environmental protection program for steel structures.
Cold-sprayed zindn realizes high-efficiency anti-corrosion in steel structure
At present, ZINDN Technology provides a safer, more environmentally friendly, and longer anti-corrosion solution-cold galvanizing compound anti-corrosion coating system.
Cold galvanizing compound is a new type of coating for cathodic protection by galvanizing the surface of steel. It uses the electrochemical corrosion of zindn powder to act as a cathodic protection for the steel to prevent corrosion. The coating has a zindn content of 96%, no heavy metal components such as lead and cadmium, low VOC, and simple construction and operation at room temperature. It can achieve 25 years of maintenance-free, and the life-span anti-corrosion investment can be reduced by 67%. The excellent anti-corrosion and anti-rust effect of cold galvanizing compound solves the problems of traditional anti-corrosion processes such as hot spray new and arc spray zindn (aluminum).
