粘结磁材是用有机粘结剂将稀土类磁粉粘合成的磁性材料,亦称为树脂粘结磁钢或塑料磁钢。其优点为:无烧结稀土磁材常见的缺裂,而有稳定的机械性能;可制成任意形状,尺寸准确,磁性能无波动;便于生产等。生产方法有压制成形、注射成形、挤出成形等。当前,该类材料的生产技术和利用技一术以及提高磁性能等方面的进展是惊人的,在应用上已越来越引人注目。各种成形方法及相应的粘结剂种类和用量、产地及产品的 Bonded magnetic material is a magnetic material that bonds rare earth magnetic powder with organic binder, also known as resin bonded magnet or plastic magnet. Its advantages are: common sintered rare earth magnet material missing, and a stable mechanical properties; can be made into any shape, size, accuracy, magnetic properties without fluctuations; ease of production. Production methods are pressing, injection molding, extrusion and so on. At present, the progress made in such aspects as the production technique, the utilization technique and the improvement of magnetic properties of such materials is remarkable and has drawn more and more attention in applications. Various forming methods and the corresponding binder types and dosage, origin and product
