Deep groove ball bearings are increasingly welcomed by industry

The corrosion of deep groove ball bearings is mainly divided into metal corrosion and human hand sweat. Metal corrosion accounts for most of them, and it is unavoidable in many cases. Hand sweat can also cause deep groove ball bearings to rust, which is mainly caused by the sweat film on the surface of the sweat. The interaction will cause electrochemical reactions and cause corrosion, but it can be avoided, such as wearing gloves that take professional parts. tool.

Metal corrosion mainly includes:

① Surface finish;

② Chemical structure and composition of metal materials;

③ solution composition and pH value on metal surface;

④ environmental media;

⑤Ambient humidity and temperature.

Anti-rust pretreatment method:

Keep the surface clean and use proper methods for cleaning. General chemical treatment cleaning, mechanical cleaning and solvent cleaning methods. After the surface is cleaned, it can be blown with dry compressed air, or it can be dried with a dryer at 120 ~ 170 ℃, and then wiped with clean gauze.

(1) Spray method

For example, some large-scale rust-proof materials cannot be oiled by soaking. It is mainly suitable for thin-layer rust-proof oil or solvent-diluted rust-proof oil, but pay attention to labor and fire protection measures.

(2) Brush coating method

When brushing, not only to avoid no accumulation, but also to prevent missed coating. Generally suitable for some special shaped products or outdoor construction equipment that are not suitable for immersion or spraying.

(3) Soaking method

The thickness of the oil film can be achieved by controlling the temperature or viscosity of the anti-rust grease. Some small items are immersed in anti-rust grease, so that the surface is coated with anti-rust grease.
