(1) Try to use solvent-free paint.
(2) Where possible, choose a impregnated paint without oxidation, such as epoxy-urethane or unmodified epoxy-base.
(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) Use paint without volatile acid.
(5) Choose a good hydrolyzable paint.
(6) Try to use mineral oil bearing grease.
(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) Plastic film with micro holes is selected to make the motor breathable before starting.When packing sealed with plastic film, paint air will stay in the bearing and moisture will dew, so try to avoid it.
(9) The grease may deteriorate under the influence of high temperature when the motor cover is cured after spraying powder or painting.
(10) Consult with the bearing manufacturer to use more effective anti-rust agent in the bearing production.
(11) In order to solve the rust completely, we can consider the motor factory, bearing factory and paint production unit to discuss together, comprehensive all aspects of the ability to solve the corrosion of the bearing.
