The rust removal methods to improve the anti-rust performance of non-ferrous metal forging parts are as follows:
(1) Immerse the oil of forging parts into the mixture after treatment;
(2) Pretreatment of forging parts;
(3) preparation of treatment fluid;
(4) Dip the pre-treated forging parts treated with silane coupling agent into the treatment solution for later use;
(5) Dip the spare forging parts into the prepared treatment agent, and wash them repeatedly with deionized water after taking them out. After drying, the rust removal of the forging parts can be completed.
This derusting method can not only quickly remove the rust stains on the surface of the forging parts, but also effectively improve the anti-rust performance of the non-ferrous metal forging parts, so that the non-ferrous metal forging parts can maintain long-term anti-rust performance after derusting.
