| titleOfInvention | METHOD FOR PRODUCING MAGNETIC GRANULES FOR ELECTROMAGNETIC APPARATUS |
| abstract | 1. A method of producing magnetic granules for electromagnetic apparatus with a magneto-boiling layer, characterized in that an aerosil additive is introduced into the strontium or barium powder hexaferrite, mixed in an electromagnetic alternating field of 50-60 kA / m, then sodium or potassium liquid glass is introduced into the resulting mixture and polyvinyl acetate emulsion and subjected to granulation, dried and fired at a temperature of 1200 ± 20 ° C for 5-15 minutes, after which the granules are cooled to room temperature and subjected to magnetization until saturation in thawed electromagnetic field with a strength of 100-120 kA / m. ! 2. The method according to claim 1, characterized in that the granulation process of the initial powder of strontium or barium hexaferrite is carried out using an aqueous solution containing 1.0-1.2 wt.% Aerosil; 1.8-2.2 wt.% Sodium or potassium water glass; A 10-12% solution of polyvinyl acetate emulsion in an amount of 15-20 wt.% Of the mass unit of the initial powder of strontium or barium hexaferrite. |
