粘结钕铁硼磁铁是快淬钕铁硼磁粉制得的塑胶磁铁.熔化的钕铁硼合金在压力下流到高速旋转的冷却轮上,并在高达106度/S的冷却速度下冷却，进而形成钕铁硼薄带，将薄带粉粹成200微米的颗粒，即快淬磁粉，将快淬磁粉与粘结剂均匀混合后，通过压铸成型或注射成型分别制成压铸成型磁铁和注射成型磁铁。压铸成型磁铁所用粘结剂为环氧树脂，注射成型磁铁所用结剂为尼龙。注射成型磁铁相对压铸成型磁铁的密度小，其相应磁性能也低。粘结磁铁的尺寸精密度很高，且不再需要二次加工。磁铁表面经树脂涂或镀镍处理后，可有效地提高其耐腐蚀性。环氧树脂涂层的厚度大约在10-25微米,表面光滑,有灰色和黑色两种.
Bonded NdFeB magnets are plastic magnets made of fastened NdFeBmagnetic powder.the molten NdFeB alloy flows to a high-speed rotatingwheel under pressure,and cooled at a cooling rate of up to 106/S,and then the formation of NdFeB boron ribbon,using striped powder to crumble into 200 microparticles,it can get fast quenching magnetic powder.And then afterhomogeneous mixing fast quenching the magnetic powder and binder,by die casting or injection molding made of die-casting magnets and injection molding magnets.Die-casting magnets used in the adhesive for the epoxy resinand injection molding magnets used for nylon.Injection molding magnets density is smaller than Die-cast magnets and its corresponding magnetic properties are also low.
粘结钕铁硼磁铁特性:
1) 一次成型并可达到精密的尺寸精度；
2) 易于直接加工成薄壁环型、瓦型等形态；
3) 可幅向充磁、多极充磁；
4) 比烧结磁铁更耐腐蚀；
5) 可开发具有更高磁性能的各向异性粘结磁铁；
Characteristics of bonded NdFeB magnets
> One molding and can achieve precision dimensional accruacy;
> Easy to be processed directly into thin-walled ring, tile and other shapes;
> Can be magnetized, multi-polar magnetization;
> It is more resistant to corrosion than sintered magnets;
> An anisotropic bonded magnets with higher magnetic properties can be
developed.
