INA bearing corrosion main points of the hands of metal corrosion and sweat, accounts for the vast majority of metal corrosion, in many cases are inevitable.
Corrosion and hand sweat can also cause INA bearing, mainly sweat will produce sweat film on its surface contact, interaction can produce electrochemical reaction caused by corrosion, but can be avoided, such as the professional take parts of tools such as gloves.
Metal corrosion mainly include: (1) surface finish;
(2) chemical structure of metal materials and components;
(3) the metal surface composition and PH value of solution;
(4) environmental medium;
(5) the surrounding humidity and temperature.
Rust pretreatment method: keep the surface clean, clean and must use the appropriate method.
General chemical treatment methods such as cleaning, mechanical cleaning, and a solvent cleaning.
Available after surface clean, dry compressed air blow dry, also can use 120 ~ 170 ℃ dryer to dry, then dry with a clean cloth.
(
1)
Spray method such as some heavy rust can't use oil soak method, mainly is suitable for the thin layer of anti-rust oil or solvent XiShiXing anti-rust oil, but should pay attention to labor and fire protection.
(
2)
Brush brush method not only avoid does not produce accumulation, also want to prevent leakage caused by the coating.
Generally applies to not share soaking or spraying some special shape products or outdoor building equipment.
(
3)
Soak method of oil film thickness can be controlled by the antirust oil temperature or viscosity to achieve.
Some small items by soaking in antirust oil, make its surface adhesion on a layer of anti-rust oil.
