Description

电磁炉加热板用磁泥粉及其制备方法
技术领域
本发明涉及一种锰锌铁氧体磁泥粉的制备方法，具体地说，涉及一种利用电磁炉加热板用磁泥粉及其制备方法。
背景技术
电磁炉作为一种新型炊具，与传统气体火焰加热、电阻加热相比，具有能效更高、加热快、环境友好、安全可靠等优点。自20世纪60年代发展至今，电磁炉在外观、控制系统、加热能效上有了长足的进步。目前，我们国内生产的电磁炉能效普遍在80％-90％之间。MnZn铁氧体磁条是电磁炉内的重要部件，作为一种常见的软磁材料，它汇集和引导磁力线，使更多的磁力线进入锅具产生更多的涡流，继而提高能效，但是目前关于电磁炉内MnZn铁氧体磁条研究很少，生产量也不大，各大电磁炉制造商在磁条选材方面也尚无具体标准，磁条供应商多而杂，供应磁条磁性能也大不相同，多因制备工艺不稳定自身一致性差，电磁炉加热过程中经常出现应力差造成磁条炸裂现象，引发事故。另外磁条由于采用高纯氧化铁、氧化锰、氧化锌及较贵的微量元素制成，因此成本相对较高。
发明内容
为解决上述问题，本发明提供一种电磁炉加热板用磁泥粉及其制备方法，其采用废旧锰锌铁氧体磁心作为基础材料，降低了成本，且所述方法制得得磁泥粉一致性高。
本发明所述的电磁炉加热板用磁泥粉，包括功能性组分和辅助性组分，其中功能性组分为Fe2O3、Mn3O4和ZnO，且该三种功能性组分的摩尔比为：Fe2O3:Mn3O4:ZnO＝52-53:35-36:11-12；辅助性组分包括CaO、Y2O3、TiO2以及V2O5,辅助性组分含量占功能性组分含量的600-1500ppm。本发明中所述的ppm均是指质量浓度。所述辅助阻性组分中，CaO、Y2O3、TiO2的总量与V2O5添加量的重量比为100-500:500-1000。其中CaO、Y2O3、TiO2的质量比满足：0.5-2:0.5-2:0.5-2。上述组分配料比例，能够提高产品的一致性，促进研磨过程更加充分。
本发明的另一个目的是提供一种利用废旧锰锌铁氧体磁心制备电磁炉加热板用磁泥粉的方法，具体而言，包括以下步骤：
(1)将废旧锰锌铁氧体磁心进行脱硅、脱铝处理；
(2)将经过脱硅、脱铝处理的锰锌铁氧体磁心粉碎后，补加Fe2O3、Mn3O4和ZnO，使配方中各组分满足下述摩尔比：Fe2O3:Mn3O4:ZnO＝52-53:35-36:11-12(经脱硅、脱铝处理后的锰锌铁氧体粉碎后其中的Fe2O3、Mn3O4和ZnO含量可以通过荧光分析仪等常规的技术手段进行分析获得，该技术手段为现有的已经非常成熟的技术手段，补加的Fe2O3、Mn3O4、ZnO用量根据测得的数据确定)；继续粉碎、混合均匀后进行造球或压片处理，然后经回转窑预烧，添加辅助性成分后研磨破碎，经喷雾造粒得到所述磁泥粉。
进一步的，步骤(1)中脱硅处理所使用的脱硅溶液为：苛性碱浓度为100-400g/L、氢氧化铝浓度50-200g/L、氧化钙浓度10-100g/L的溶液。其中具体的处理条件为：将废旧锰锌铁氧体磁心置于上述溶液中，在90-105℃陈放1-3小时后搅拌30-60分钟完成脱硅步骤。
进一步的，步骤(1)中脱铝处理步骤为：将脱硅处理后的磁心放到苛性碱浓度为100-400g/L的碱性溶液中浸泡10-30小时，强烈搅拌30-60分钟，后经纯水过滤完成脱铝步骤。
优选的，经过脱硅、脱铝处理后，得到的硅铝总含量小于200ppm，本发明中所述的ppm均是指质量浓度。
进一步的，步骤(2)中回转窑预烧温度为900-1000℃。
进一步的，步骤(2)中功能性组分和辅助性组分混合，破碎研磨至颗粒尺寸为1-3μm，经喷雾造粒后其颗粒尺寸优选为不超过2μm。
与现有技术相比，本发明的有益效果是：
(1)原料采用回收的废旧锰锌铁氧体磁心，既能够解决废旧铁氧体磁心的去向问题，更能够极大的降低电磁炉加热板用磁泥粉的生产成本；
(2)各组分用量、及脱硅、脱铝工艺，能够将影响产品性能的硅、铝元素出去，能够提高磁泥粉的合格率和一致性，减少使用过程中的炸裂现象；
(3)废旧锰锌铁氧体磁心惰性较高，在回收过程中产生的磁心应力较小，而本发明中辅助性组分的加入，能够提高材料的耐热性能和强度，避免电磁炉加热过程中出现安全事故。
