Description
(54) СПОСОБ ПОЛУЧЕНИЯ ПОРОШКОВ ФЕРРИТОВ(54) METHOD FOR OBTAINING FERRITE POWDERS
риодически контролиру рН среды. При рН 7 реакци считаетс законченной и перемешивание прекращаетс . После оседани ферритового порс ка остаточную жидкость сливают, внос т 5 л 10%-го раствора поливинилового спирта, влажность суспензии доводитс до 30-40%, после чего суспензи готова дл получени пресс-порошка методом распылительной сушки. Перед распылением суспензию перемешивают в течение 1-2 ч дл установлени адсорбционного равновеси .Periodically monitors the pH of the medium. At pH 7, the reaction is considered complete and mixing is stopped. After the ferrite powder has settled, the residual liquid is drained, 5 liters of 10% polyvinyl alcohol solution are added, the moisture content of the suspension is adjusted to 30-40%, after which the suspension is prepared to obtain a spray powder. Before spraying, the suspension is stirred for 1-2 hours to establish adsorption equilibrium.
При вы снении вли ни хлористого aivIмoни в модифицированном порошке, на фо1 4рвочные свойства установлено, что при сушке ,C.u легко разлагаетс и вли ни на формовочные свойства пресс-порошка ; не оказывает. Это позволило исключить операцию отмывки отWhen determining the effect of chloride aivI in modified powder, on the base of the filler properties, it was found that during drying, C.u easily decomposes and influences the molding properties of the press powder; does not render. This allowed to exclude the operation of washing from
, в результате чего выход модифицированного порошка увеличилс на 0,1% при внесении 1,26 г . на 500 г ферритового порошка и на 1% при внесении 12,6 г на то же количество порошка феррита.whereby the yield of the modified powder increased by 0.1% with the addition of 1.26 g. 500 g of ferrite powder and 1% when making 12.6 g of the same amount of ferrite powder.
В таблице приведены формовочные свойства пресс-порошка марганёц-цин-кового .феррита и электромагнитные параметры готовых изделий, полученных из него.The table shows the molding properties of manganese-zinc ferrite press powder and the electromagnetic parameters of finished products obtained from it.
Как видно из данных таблицы, формовочные свойства пресс-порошка повышаютс , (к пластичности 0,920 ,93), улучшаетс качество прессовок , в результате чего почти полностью исключаетс брак на стадии прессовани . Это особенно важно при формовании изделий сложной конфигурации .As can be seen from the table, the molding properties of the press powder increase (to plasticity of 0.920, 93), the quality of the compacts is improved, as a result of which the scrap at the pressing stage is almost completely eliminated. This is especially important when forming items of complex configuration.
