In the process of building construction, the importance of steel bars is unquestionable. The safety of buildings is also closely related to the corrosion resistance of steel bars. As energy-saving and environmental protection policies begin to extend to the construction field, powder coatings begin to appear in the research plan for corrosion-resistant steel bars. Steel bars will rust when they are wrapped in highly alkaline concrete for a long time, shortening the service life of the steel bars.

Powder coating bring change

Among them, epoxy resin coated steel bars have attracted market attention due to their simplicity and effectiveness. Epoxy resin coated steel bars are electrostatically sprayed with epoxy powder coating on the surface of steel bars, and then cured at high temperature to form a uniform epoxy powder coating film protective layer that can cover the entire surface of the steel bars. The epoxy powder coating film protective layer can effectively slow down the corrosion rate of steel bars, improve the corrosion resistance of steel bars, and extend the service life of buildings.
