Hengdian Kim Dae-magnetic NdFeB magnet factory ---- cleaning problems before plating, there is a part of the preliminary work in question is not in place, then, will be to follow the NdFeB magnet NdFeB plating defects adverse effect magnets price, plating may NdFeB magnets wholesale prices blistering, peeling, etc. Defective product is no bad market value. If defective products once they are applied to the NdFeB magnet strength on important equipment, it will cause the machine failure. Have serious consequences. Before plating, preliminary work NdFeB: NdFeB magnetic materials belong microporous materials. Because of the porous so before plating process to bring a lot of trouble. The first product on the surface of the alkaline and acid substances and processing outside to clean up the dirt, but also clean the pores of dirt, which is the hardest. Hengdian Kim Dae-magnetic Factory ----- magnet manufacturers briefly thni magnet magnet-type crystal structure is what the manufacturers tell you, Th2Ni17 crystal structure is an important type of rare earth permanent magnet material structure, and it belongs to the hexagonal system space group P63 / mmc. A single cell by two Th2Ni17 molecules, a total of 38 atoms. Two of Th (or R) atoms occupy b crystal sites, the other two magnets. 4f crystal which is dumbbell-bit, which consists of Ni or B or Fe atoms to occupy, equivalent Kyoko was rare bit CaCu5 Go c crystal structure on or Ni, Fe and other atoms of needle exchange results.
