Powerful magnets to put for a long time after surface will appear bright white or other color spots, gradually will become rusty spot, usually under normal circumstances, powerful magnets plating surface coating is not easy to rust spots, generally the cause of rust spots will usually have the following categories: 1.
Powerful magnet store place is too wet, poor indoor and ventilated sex, big temperature difference between the floating of the site;
Powerful magnet before plating the surface layer of dirt, without a clear;
Surface plating or production process the length of the insufficient;
Powerful magnet or damaged caused by bad packaging sealing magnet oxidation;
High-temperature magnet conform to the standards of electroplating products, under normal circumstances, magnet for electroplating coating surface layer should not be rust spots.
The sentence pseudo original deposit ndfeb strong magnet should prevent the following forms: in too humid, indoor and ventilated not too good place;
Temperature changes a lot, even the salt fog test standard products for a long time store in the bad environment can form a rusty spot.
When plating products stored in harsh environment, base layer more reaction with water, can lead to a base layer and the adhesion strength of the coating is reduced, serious when still can cause local pulverization, basal and natural peeling.
Electroplating products are placed in high humidity for a long time, should be placed in a cool, dry place.
