INA bearing main points metal corrosion and corrosion of the hand of the sweat, metal corrosion account for most part, many cases can avoid. And hand sweat can cause the INA bearing corrosion, mainly is the sweat on the surface contact will produce sweat membrane, interaction will happen electrochemical reactions and causes corrosion, but can avoid, such as take professional take part gloves tools.
Metal corrosion mainly has:
(1) surface finish;
(2) the chemical structure of metal materials and components;
(3) the metal surface solution composition and PH value;
(4) the environment medium;
(5) surrounding the humidity and temperature.
Rust pretreatment methods:
Keep clean surface, and clean must use an appropriate method. General chemical dealing with cleaning, mechanical cleaning and have solvent such as cleaning method. Face clean compressed air can be used after drying blow dry, also can use 120 ~ 170 ℃ dryer for dry, then use clean dry gauze.
(1) spray method
Some big things such as antirust cannot take soaking method with oil, mainly is suitable for the thin layer or solvent XiShiXing oily-type temporary, but be aware that labor and fire protection measures.
(2) brush besmear of
When brushing besmear not only to avoid do not produce accumulation, also want to prevent result with the leak. Generally applied in not share or spray some special for the products of the shape or outdoor building equipment.
(3) soaking method
Oil film thickness can control the temperature of the rust or viscosity oil to achieve. Some small items by soaking in the rust of oil, make its surface adhesion on a layer of rust grease.
