Worldwide Corrosion Day

World Corrosion Day is observed every year on April 24. What do you know about corrosion and corrosion prevention? Actually, what you think may not be what you think...

The "advent" of steel has brought a lot of convenience to people, and also brought people to see a more wonderful world, such as cross-sea bridge, bullet train, automobile and so on. From then on, life has entered a new era. Steel is almost indispensable in daily life, but people often ignore corrosion, although the pace of the slow but serious consequences of major problems.

Corrosion, which is a common problem facing all mankind, involves resource consumption, environmental pollution, human health damage and so on. The 2013 pipeline explosion in Qingdao, Shandong province, was caused by a leak caused by corrosion. The heavy metal ions produced by corrosion can contaminate soil, plants and water, as well as threaten human health. According to statistics, the total cost of corrosion in China was about 5% of GDP in 2017, and the cost of corrosion was greater than the total loss of all natural disasters. Natural disasters cannot be controlled, but corrosion is different.

Corrosion is a universal problem, and the good news is that there is a solution. Scientists point out that at least 30% of the losses caused by corrosion can be reduced through science popularization, research and technology application to reduce the loss, resource consumption and pollution. To solve this problem, the government, enterprises and the whole people need to pay attention to it, and start from understanding corrosion and paying attention to corrosion.
