NdFeB materials because of the straightforward oxidation and corrosion,as a way to make sure the magnets beneath the cruel enviroment security.SUNS MAGNET steady floor safety expertise analysis and improvement to enhance the extent of floor safety.
The floor coatings are typically Ni, Cu, Cr, Au, black and blue ZN, and so forth.The magnet floor of the colour will likely be completely different rely on the completely different electroplating, the size of save time will likely be completely different..
The comparative examine of the Ni, Zn, epoxy resin, PARYLENE-C coating of neodymium iron boron magnet in three sorts of answer on the magnetic properties of the affect, we discovered: in acid, alkali and salt, polymer coating on the magnetic protecting impact finest, epoxy resin has a comparatively poor, Ni coating instances, Zn coating is comparatively poor.
Zinc: appear on the floor to be silver white, do 12 – 48 hours salt spray, with the usage of some glue, resembling AB glue, adhesive, resembling electroplating could be saved for two to five years.
Nickel: seemingly stainless-steel shade, set to remain within the air floor is tough to be oxidized, and the looks of handsome, good gloss, plating could be over 12 – 72 hours salt spray check. The drawback is that it cannot be used for bonding with some glue, which can trigger the coating to fall off. Now available on the market for nickel – Copper – nickel plating on the way in which, do 200 – 120 hours salt fog.
Copper: appeared within the business, NdFeB magnetic business isn’t used, the looks of yellow.
Chromium: chromium electroplating business is comparatively uncommon, the associated fee may be very excessive, the Peculiar Firm cannot settle for. However its capability to rot may be very sturdy, it’s tough to react with different substances. Primarily used within the sturdy acidity of the place.
Black zinc: in keeping with buyer necessities could be neodymium iron boron magnetic merchandise floor remedy to black, in electroplating course of is especially within the foundation of galvanized by chemical remedy with a layer of black protecting movie, this movie will also be to safety merchandise do use, development within the salt fog time, extended oxidation between. However its floor is straightforward to be scratched, lose its protecting impact. Now use the particular person may be very little, and many of the resin as an alternative of.
Kim: Yellow Gold jewellery we see most Shangjie some stalls for gold or copper. Gold makes the product appears to be like like gold may be very stunning, typically used for the ornament business, our merchandise will also be utilized in gold plating, used for magnetic jewellery.
Epoxy resin is: after the nickel plated product once more on the skin with a layer of resin paint, the business lately is the market, its improvement velocity may be very quick, now every kind of electroplating merchandise for many individuals, its greatest benefit is can do the colour you need.
In selecting what materials to make use of, must be primarily based on the completely different use of the atmosphere to pick out the suitable coating. With out the coating producers haven’t the identical, which is the principle motive for chamfering and plating time size. Within the case of magnetic plating will not be perceive, we must always distinguish the standard of the coating is sweet or unhealthy, in reality, there is likely one of the simplest and environment friendly manner is to take a look at the coating, the coating, the higher the standard of the higher.
