Description

Technical field

[0001] The invention relates to the technical field of neodymium iron boron production equipment, in particular to a method for manufacturing a pneumatic sealing gasket. Background technique

[0002] Neodymium iron boron magnetic material, as the latest result of the development of rare earth permanent magnet materials, is called "magnet king" due to its excellent magnetic properties. NdFeB magnetic material is an alloy of praseodymium, neodymium, boron and iron, also known as magnet steel. Neodymium iron boron has extremely high magnetic energy product, coercivity and energy density. It has been widely used in modern industry and electronic technology, making instrumentation, electro-acoustic motors, magnetic separation magnetization and other equipment miniaturized, lightweight, Thinning becomes possible.

[0003] NdFeB contains a large amount of rare earth elements neodymium, iron and boron, and its characteristics are hard and brittle. The advantages of neody...
