Several methods of LongYe bearing rust

Surface cleaning: cleaning must depend on be antirust surfaces of the nature and the condition, select the appropriate method. General common have solvent cleaning method, chemical processing cleaning and mechanical cleaning method.

2) surface drying after rinsing available filter dry compressed air blow dry, or use 120 ~ 170 ℃ drying device for drying, also can use clean dry gauze.

Coating anticorrosive oil method

1) infusion method: some small items by soaking in the antirust oil, let the surface adhesion on a layer of antirust oil method. Oil film thickness can be through the control antirust oil temperature or viscosity to achieve.

2) brush coating used in do not apply for or spraying outdoor construction equipment or special shape of the products, brush besmear should pay attention to both do not produce accumulation, also want to pay attention to prevent leak painting.

3) spray method some large antirust things can't by soaking method oil, general use approximately 0.7 Mpa pressure filtering compressed air in the air clean place spraying. Spray method suitable solvent XiShiXing rust-preventative oil or thin layer rust-preventative oil, but must use perfect fire and labor protection measures.

The main factors affect metal corrosion have?

Metal corrosion is composed of internal and external factors arising out of, to sum up mainly include:

(1) the metal material itself chemical composition and structure;

(2) the metal surface finish (oxygen concentration difference cell corrosion);

(3) and metal surface contact solution composition and pH value;

(4) the environment temperature and humidity;

(5) and metal surface phase contact with various environmental medium.
