Background
Neodymium magnet (Neodymium magnet), also known as NdFeB magnet, is a generic name for powerful magnets having the chemical formula Nd2Fe14The neodymium iron boron permanent magnet has the advantages of high cost performance, good mechanical characteristics, small volume, light weight and strong magnetism, and the magnetic force can reach about 3500 gauss in a bare magnetic state, so that the neodymium iron boron permanent magnet is the magnet with the best cost performance at present, and the neodymium iron boron permanent magnet material has wide application in modern industry and electronic technology due to the advantage of high energy density, such as hard disks, mobile phones, earphones, tools powered by batteries and the like. The general preparation process of the neodymium iron boron magnet can be divided into bonding neodymium iron boron and sintering neodymium iron boron, wherein the bonding is actually injection molding, and the sintering is vacuum pumping and high-temperature heating molding.
The neodymium magnet raw material powder is put into a sintering furnace in batches after being subjected to dry pressing forming for sintering, and because the neodymium magnet blocks after being subjected to dry pressing forming are extremely easy to oxidize in the air, the non-sintered neodymium magnet blocks must be stored in vacuum, while inert gas is often filled in a simple plastic bag in the prior art, and then the non-sintered neodymium magnet blocks are put into the plastic bag for storage. The existing storage mode is very easy to bring air into the plastic bag when the non-sintered neodymium magnet blocks are placed in the plastic bag, and the neodymium magnet blocks cannot be effectively stored in vacuum.
SUMMERY OF THE UTILITY MODEL
