What are rust inhibitors? It is an inhibitor used to inhibit chemical corrosion of steel bars. There are two types of rust inhibitors. One is the spray type, which is often used in structural reinforcement. One is the incorporated type, which is used when re-pouring concrete.
Rebar corrosion affects the durability and safety of buildings, causing damage to reinforced concrete structures and has become a worldwide problem. The main cause of steel corrosion is chlorine salts , On the one hand, chlorine salt comes from concrete raw materials, such as mixing water, sea sand, anti-icing salt, salt spray and chlorine salt (or chlorine-containing salt) admixtures, etc.;
On the other hand, due to the use environment, chloride ions can penetrate the concrete and reach the surface of the steel bars, destroying the oxide passivation film on the surface of the steel bars. When the steel bars are corroded by sodium chloride ions or sulfate ions, the steel bars will quickly rust and As it ages, the steel bars will break irregularly, and the concrete will also crack, affecting its own strength and the quality of the entire building.
