Motor injection magnet wholesale generally put today's strong magnet glue do "permanent magnet ", although it is called permanent magnet, electronic pump plastic magnetic wholesale must also have a strong life. In fact, although it is a permanent magnet, it will disappear to the end of the life, so how to do can increase the life of the magnet cost less, and then increase the life of the magnet to reduce and reduce the cost.

Precision plastic magnetic wholesale in the use of the link must be through a long working time will cause magnetic weakening, in this site before the above has detailed introduction of the "magnet in the work will not be easy to magnetic weakening ", on the magnet has explained some applications when the life is not easy to reduce the cause. So the key to detail how to increase the life of the magnet as the dominant. The surface magnetic field strength of a strong magnet is positively correlated with the size of a very small case that can be adsorbed by activated carbon. Strong magnets should be stored in conditions that have no other adverse effects on magnetism, so the temperature and humidity of the natural environment will interfere with its magnetism. Superstrength mostly refers to Ndfeb, a chemical element that is so easily corroded and oxidized by air that it must be coated. Ndfeb is stored according to surface treatment, even if there is no direct influence of the natural environment, the application life of the magnet will be longer under the condition of drying.

It is very easy to rust the magnet, or the information of electroplating process is not very good, generally can not be used for a year will delamination. The internal structure of powder metallurgy commodities is different from that of forged commodities. The internal structure is loose and fused. There is high thermal stress inside the magnet, so the particles tend to disperse. With the chemical action, it's likely to become a powder in a short time. There is also high temperature demagnetization. Even adding magnetism again won't fix the original magnetism.
