Description

technical field [0001] The invention belongs to the technical field of chemical rust removal treatment on the surface of steel plates, and in particular relates to a rust remover. Background technique [0002] The surface of the steel plate has a galvanized layer or other protective layer when it is produced to prevent it from being corroded and rusted by the air. The steel plate often needs to be cut in daily use, and the cutting place is prone to rust, which needs to be derusted in time. The strong acid of the agent is very corrosive to the galvanized layer and destroys the protective effect of the galvanized layer. Contents of the invention [0003] The object of the present invention is to provide a rust-removing and anti-rust agent with reasonable formula, good anti-rust and rust-removing properties, and no damage to the galvanized layer of the steel plate. [0004] Technical solution of the present invention is: [0005] A rust remover and antirust agent is charact...
