1) use solvent-free paints whenever possible.
(2) if possible, use a non-oxidizing impregnating paint, such as epoxy-urethane or Epoxy- based impregnating paint.
(3) using melamine alkyd varnish, should adjust the curing temperature and curing time and curing temperature slightly higher than 130 ℃ (135 ℃) and curing time is more than 180 min advisable, and must be strictly implemented process, especially in high temperature and wet season, because from the perspective of the concept of rust, paint factory samples of paint drying (curing) prescribed by the time, is not necessarily sufficient, motor have specific inner shape.
(4) paint without volatile acid.
(5) choose a paint with good resistance to hydrolysis.
(6) use mineral oil bearing grease as far as possible.
(7) motor factory inject grease on their own, in order to avoid water vapor in the air and dust into the bearing noise and may cause a corrosion factors, grease container should be sealed, even so should note fat and fat injection quantity according to the standard should be certain, such as using 6202 bearing, reference, within the range of 0.60 ~ 0.80 g fat injection process should be kept clean and dry.
(8) choose plastic film packaging with micro holes, so that the motor can breathe freely before use.When sealed with plastic film, the paint gas will remain in the bearing and the water will dew.
(9) the grease may deteriorate under the influence of high temperature when the motor cover is sprayed powder or painted and solidified.
(10) negotiate with bearing manufacturers to use more effective anti-rust agent in bearing production.
(11) in order to completely solve the paint rust, can consider by the motor factory, bearing factory and paint production unit to discuss together, comprehensive capabilities to solve the bearing rust.
