A surface cleaning: cleaning must be according to the nature of the surface to be rust-proof and the conditions at the time, selected the appropriate method. Commonly used solvent cleaning met hod, chemical processing, cleaning and mechanical cleaning method.ball bearing suppliers
Available surface is dry and clean the filter dry compressed air, or 120 ~ 170 ℃ dryer to dry clean gauze can also be used dry.ball bearing companies
Why hand sweat can cause metal corrosion
Sweating is inevitable to prevent the hand sweat corrosion caused by the production staff should wear gloves, gloves, pick up parts or special tools, applications. They Do not hand contact with the product.
Human sweat is a clear, colorless or pale yellow with a salty taste was mildly acidic liquid, its pH value of 5 to 6. Sweat, contact with the metal to form a layer of sweat film on the metal surface metal of sweat film will cause electrochemical reaction and corrosion of metal. In addition to containing sodium, potassium, calcium, m agnesium, it also contains a small amount of urea, lactic acid, citric acid.

Coated with rust preventive oil
3 spray some large rust-proof material can not be used immersion coated with oil, usually with about 0.7Mpa pressure filtration of compressed air to spray the air clean place. The spray application of diluted anti-rust oil or thin layer of anti-rust oil, but must be used to improve fire safety and labor protection measures.
4 soak method: some small items soaked in anti-rust grease, let adhesion layer antirust oil. Film thickness can be achieved by controlling the temperature or viscosity of the antirust oil
5 brushing method used for outdoor construction equipment, or special shapes NA soak or spray products, we should pay attention to the brush does not produce accumulation and pay attention to prevent leakage Tu.

What are the main factors that affect metal corrosion
1 with the metal surface in contact with the various envir onmental media.ceramic ball bearing
2 metal material chemical composition and structure;
3 Ambient temperature and humidity;
Metal corrosion is caused by a variety of intrinsic and extrinsic factors, summarized in:
4 metal surface finish (the difference of oxygen concentration cell corrosion);
Contact with the metal surface, the solution composition and pH;
