钕铁硼的镀层Neodymium iron boron coating
Because the matrix of Nd-Fe-B magnetic steel is easy to be oxidized and corroded, different coatings are generally required to protect the magnetic steel. The commonly used coatings are: nickel copper nickel, blue white zinc, color zinc, epoxy, phosphating, Teflon
镍铜镍镀层磁钢Nickel copper nickel coated magnetic steel
Nickel copper nickel coating has excellent corrosion resistance, hardness, wear resistance and other comprehensive physical and chemical properties. It is exposed to complex atmospheric environment to ensure long-term stability of appearance and internal performance and long service life. Neodymium iron boron is one of the most common coatings.
蓝白锌镀层磁钢Blue white zinc coated magnetic steel
The zinc coating is generally thin and has relatively good corrosion resistance. After passivation, the coating has a beautiful appearance and beautiful color. The "bone effect" of the coating at the center and corners of magnetic steel is not obvious, which can also be met for products with tight product tolerance. It can be used in limited corrosive occasions with resistance to short-term pollution and discoloration.
彩锌镀层磁钢Color zinc coated magnetic steel
Color zinc coating has the characteristics of ordinary blue and white zinc coating, and has higher corrosion resistance than blue and white zinc coating. It can be used in harsh atmosphere.
环氧树脂镀层磁钢Epoxy resin coated magnetic steel
Epoxy resin has good physical and chemical properties, excellent bonding strength to the surface of metal and non-metallic materials, good dielectric properties, small variable shrinkage, good dimensional stability, high hardness, good flexibility, and stable to alkali and most solvents. Our company adopts the process of electroplating nickel copper and then coating epoxy resin. The products have excellent bonding ability and corrosion resistance.
磷化镀层磁钢Phosphate coated magnetic steel
Phosphating is used to protect the base metal and prevent the metal from corrosion to a certain extent. It has the characteristics of no coating thickness. Priming before painting can improve the adhesion and anti-corrosion ability of the paint film.
特氟龙镀层磁钢Teflon coated magnetic steel
Teflon has unique and excellent heat resistance (180 ~ 260 ℃), low temperature resistance (- 200 ℃) and dielectric properties. It has the highest working temperature (260 ℃) and the best chemical stability. Except for molten alkali metal, high temperature and difluorination atmosphere, no other chemical substances can erode it. It also has excellent weather resistance and can be used outdoors for more than 10 years. It has low friction coefficient and its lubricity, especially self lubrication
