Sintered ndfeb magnets to join the changes of the performance of the lubricant
To join the changes of the performance of the lubricant of sintered ndfeb magnet ndfeb magnet magnetic powder particles were more bad of the liquid, if add the appropriate lubricant and words in the powder.
Can reduce friction, prevent powder particles bonded together, can effectively improve the liquidity of powder.
In the stress and the magnet magnetic field intensity under the same conditions, to add antioxidants 0.
04% of the magnetic powder for sample, carries on the experiment on the influence of magnetic can lube.
The result shows that when adding 0.
3% of the lubricant, because the magnetic particles rotational resistance decrease, powder orientation degree increase, increase the performance of permanent magnet of magnetic magnet;
When too much lubricant additives, the magnet in the lubricant, zinc stearate, residues too much, cause the loss of the permanent magnet performance of magnets.
