[0002] Rust conversion liquid is a kind of chemical agent for converting the rust on the surface of metal into a protective film, so as to achieve the purpose of rust removal and rust prevention. Specifically, rust conversion liquid combines with iron ions in rust through chemical reaction to form a stable conversion film. This conversion film not only effectively isolates moisture to prevent further corrosion of the metal surface, but also can be used as a primer to improve the rust prevention effect of the workpiece.
