Can the rusty silicon steel sheet be used?
1, the appearance is ugly;2, short circuit between the pieces, serious iron will cause fever;3, affect the insulation and life of the motor, serious fire may occur;4, easy to produce eddy current, magnetic permeability decreased, decreased efficiency, high temperature rise transformer, easy to burn out.
No, but generally, the silicon steel sheet is not very rusty, because the surface of the silicon steel sheet has a coating, and the semi organic coating and insulating paint can effectively prevent rust. But if exposed to the air for a long time, the side is easy to rust.
In view of the above, when necessary, should also be good rust prevention:1, painted antirust oil;2, packaging, try not to touch the water;3, place, try not to place in damp place.
