The role of waterborne rust inhibitors in the steel market

The water-based rust inhibitor is a water-based rust-proof solution. The products that can be used are steel, iron and other materials to prevent them from rusting. We need to mix the rust inhibitor and water in a certain proportion according to the requirements of the rust prevention period, so that the rust prevention period can reach several days or several months. If the packaging condition of the product is better, use the moistureproof outside. The packaging conditions are stored in a dry environment, and our anti-rust effect can be more than one year.

In the process of production, storage and transportation of steel materials, if anti-rust treatment is not carried out, rust will occur in a short period of time, which will adversely affect the appearance and function of the steel products. If the corrosion is serious, the steel may be directly scrapped. The rust of steel has caused huge losses to the national economy, and the annual steel scrapped by rust in the world amounts to tens of millions of tons.

China's economic losses caused by corrosion in 2000 reached 500 billion yuan, so the discussion of anti-rust liquid plays an important role in the maintenance of steel materials. Most of the metal water-based anti-rust liquids used in the past contain sodium nitrite. The nitrite-based water-based anti-rust liquid has obvious advantages such as low cost, excellent effect, convenient use and easy removal, so it is widely used, but it is proved Nitrite can be converted into carcinogens and its use and emissions are severely restricted.

Due to environmental protection and other reasons, people have been working on non-nitrite environmentally friendly water-based rust inhibitors for many years and have made great progress. Although the anti-rust oil has good rust resistance, it has high cost and brings difficulties to the post-processing of steel products. In recent years, the research on environmentally friendly water-based rust inhibitors has received extensive attention at home and abroad, especially the development of long-acting water-based rust inhibitors has become a trend.
