Shanghai Wannan electric motor bearing on anti rust treatment methods are described
(1) use of solvent free paint as much as possible.
(2) the use of cyanohydrin trimer acid dipping paint, adjusting the curing temperature and curing time, curing temperature to slightly more than 130 DEG C (such as 135 DEG C) and the curing time is larger than 180 minutes is appropriate, and must be strictly implement process, especially in hot and humid season, because from the point of view of the concept of rust, stipulated in the samples of paint plant paint drying (curing) time, not necessarily fully motor specific intrinsic shape.
(3) if there is a possibility that the use of a non oxidizing component of a dip coating, such as an epoxy (Epoxy-urethane) or an unmodified epoxy (Epoxy-) - based varnish.
(4) choose a good paint.
(5) the use of non volatile acid paint.
(6) motor factory in self injected grease, to avoid water vapor in the air and dust from entering the bearing noise and may cause corrosion factors, lubricating grease container should be sealed, even in the grease should also be the case, and the amount of grease according to the standard should be certain, such as adopting 6202 bearing, the reference value in the range of 0.60 to 0.80g, grease injection process should be kept clean and dry.
(7) use of mineral oil as far as possible the bearing grease.
(8) the effect of high temperature grease in the motor cover after the curing of the paint or powder may deteriorate.
(9) the use of a microporous plastic film packaging, so that the motor has a certain air permeability before. Sealed with plastic film, the paint will stay in gas bearing, water condensation, should try to avoid.
(10) for the complete solution of paint rust, can be considered by the motor manufacturers, bearing production plant and paint production units to discuss, comprehensive ability to solve the bearing of the corrosion.
(11) in consultation with the bearing manufacturer, using more effective anti rust agent in the production of bearings.
