Novel process for producing pressure-resistant ferrite powder
The invention discloses a novel process for producing pressure-resistant ferrite powder, which comprises the following steps: weighing the following raw materials in percentage by weight: 40-80wt% of ferric oxide, 15-30wt% of manganese oxide, 10-20wt% of zinc oxide and 1-5wt% of auxiliary materials, pouring the raw materials prepared in the previous step into a dispersion machine, then adding deionized water, and uniformly mixing, and pouring the slurry obtained in the previous step into a spherical grinding machine for grinding, controlling the rotating speed of the grinding machine to be 1000-2000r/min, controlling the grinding time to be 0.5-3h, pouring the ground slurry into a filter press for filter pressing dehydration, and controlling the water content of the dehydrated powder to be 5-10wt%. By adopting the production process designed by the invention, the pressure-resistant ferrite powder can be prepared, the energy-saving effect is realized by reducing the air flow rate in the rotary kiln and reducing the heat consumption during production, and the resistivity of the pressure-resistant ferrite powder produced by the process is much larger than that of metal and alloy magnetic materials, so that the pressure-resistant ferrite powder is more stable in performance. And the dielectric property is relatively high.
本发明公开了一种耐压铁氧体料粉生产新工艺，包括如下步骤：将原材料按下述配比称重：氧化铁40‑80wt%、氧化锰15‑30wt%、氧化锌10‑20wt%、辅料1‑5wt%，将上述步骤配制好的原料倒入分散机中，然后加入去离子进行混合均匀，将上述步骤获得的浆料倒入球形研磨机中进行研磨，研磨机的转速控制在1000‑2000r/min，研磨时间控制在0.5‑3h，将研磨好的浆液倒入压滤机中进行压滤脱水，脱水后的粉料含水量控制在5‑10wt%。通过采用本发明设计的生产工艺，能够制备耐压的铁氧体料粉，而且在生产的时候，通过降低回转窑内风流速，减少热量消耗，来实现节能的效果，而且通过本工艺生产的耐压铁氧体料粉的电阻率比金属、合金磁性材料大得多，而且还有较高的介电性能。
