In industrial processing, the surface of brass parts is prone to oxidation and corrosion, which seriously affects the quality, appearance and price of brass parts. The brass rust prevention process is an essential process in the brass surface treatment process. So, how to deal with brass parts to prevent rust?

At present, in the brass surface treatment process, the anti-rust processes include passivation, chemical plating, electroplating, sealing,   painting, etc. Due to the mature, simple and easy-to-use brass passivation process, it has been widely used in the protection of brass parts.

  In general, the brass passivation treatment process includes degreasing cleaning, rust cleaning, bright cleaning, passivation treatment and other processes.

Degreasing and cleaning of brass parts:

Immerse the brass parts to be washed in the tank solution of the prepared brass degreasing cleaning agent to achieve the purpose of degreasing and decontamination on the brass surface. The degreasing time needs to be adjusted according to the serious oil contamination on the surface.

At present, in the brass degreasing and cleaning process, environmentally friendly copper degreasing agents are generally used for cleaning operations. The environmentally friendly brass degreaser has no corrosion inhibitor component, which greatly reduces the probability of brass parts being corroded during the cleaning process.

Rust removal of brass parts:

The cleaned brass parts are immersed in the tank solution of the prepared brass rust remover to achieve the purpose of removing rust and scale on the brass surface.

At present, the brass rust removal process generally uses an environmentally friendly copper rust remover for rust removal and cleaning operations. The environmentally friendly brass rust remover has the advantages of strong rust removal ability, fast rust removal speed, good environmental protection performance and wide application range.

Chemical Polishing of Brass Parts:

Immerse the washed brass parts in the bath of the prepared brass polishing agent to achieve a bright brass surface.

At present, in the brass polishing process, the environmentally friendly brass rust remover used does not contain strong oxidizing acids such as sulfuric acid, nitric acid, chromic acid, and hydrochloric acid, and does not contain heavy metal ions. It is simple and practical, and the polishing effect is better than that of traditional pickling. . During the polishing process, no irritating gas or yellow smoke will be produced.

Brass parts passivation protection:

The washed brass parts are immersed in the tank solution of the prepared brass passivator to achieve the purpose of long-term rust and oxidation prevention of brass parts.

The brass passivation agent used in the passivation protection of brass parts has the advantages of stable physical and chemical properties, non-toxic, odorless, non-volatile, non-deliquescent, non-decomposing, non-sublimating, non-absorbing dust and harmful gases such as H2S and SO2.

Brass parts after passivation treatment can effectively resist the erosion of hot and humid salt spray and bacteria, and the passivation film has good wettability and high corrosion resistance.

Brass passivation agent has triple functions of dehydration, discoloration and rust prevention.
