(1) Use solvent-free paint as far as possible for vibration machinery.
(2) It is best to use impregnating varnishes that do not contain oxidizing components , such as Epoxy-urethane -based or unmodified epoxy -based impregnating varnishes.
(3) When using cyanuric alkyd varnish , should be adjusted to the curing temperature and curing time , curing temperature slightly higher than 130. deg.] C ( such as 135 deg.] C ) and the curing time is greater than 180min appropriate , and the process must be strictly enforced , in particular in hot and humid season , vibration sieve as rust from the concept point of view , the paint in the paint sample of a predetermined drying ( curing ) time , it is not necessarily sufficient , the motor has a specific internal shape.
(4) Use paint without volatile acid.
(5) Choose paint with good hydrolysis resistance.
