Bearing anti-rust primer

In the use of the bearing, in addition to routine maintenance needs to prevent its damage, also need to prevent bearing rust, so bearing rust? More to cure treats, bearing made of metal, so let's start from the metal rust. '01 selecting corrosion-resistant materials mainly is to use non-ferrous metal alloy and stainless steel, the second is the choice of surface layer. Metal surface prefabricated metal ( Alloy) Or non-metallic coating: 1. Black conversion film: ( Blue) , phosphating, anodic oxidation; 2. Surface alloying nitriding, zinc impregnation, siliconizing, aluminized, chromizing, etc; 3. Metal coating: spray plating metal, metal, hot dip plating, electroless plating, etc. ; 4. Non-metallic coating, enamel, ceramics, paint, plastic, rubber, etc. ; 5. Coating antirust materials: anti-rust water, cutting fluid, the gas phase inhibitor, can peel plastic, rust-proof oil, antirust grease, etc. 02 other anticorrosion method of cathodic protection: in a sacrificial anode and cathodic protection of electrochemical method. Magnesium in sea water, as well as its block as anode with associated steel plate, make steel plate with current cathodic protection. Underground pipelines and chemical equipment, but also outside another anode and current steel ( The cathode) Be protected. Control environment corrosion: 1. Dehumidifier and humidification are adopted to decrease the temperature, relative humidity control in less than 60 ~ 70%, metal corrosion slow; Relative humidity under 60% when, non-metallic not gone mouldy; 2. Nitrogen charging or vacuum packing seal can delay the rust; 3. Packing internal corrosion inhibitor; 4. Iron and steel products in electric furnace heating ( High temperature) , form a protective atmosphere in the furnace or home heating. To sum up, a lot of methods to prevent rust bearing. In addition to the above methods should consider many factors after judgment, such as: parts of the work environment, the parts service condition, production security, etc. ( Professional motor bearing application solutions provider) Focus on miniature high speed, low noise, long life motor bearing telephone: fax: an article on the sales @ : bearing roller and roller processing!
