Description

一种制备超细硅酸锆的方法
技术领域
本发明属于陶瓷技术领域,具体涉及一种制备超细硅酸锆的方法。
背景技术
超细硅酸锆粉是利用锆英砂作为原料,通过研磨将锆英砂粉碎到一定的细度,经物理方法除杂后烘干收集,得到超细硅酸锆产品。
超细硅酸锆粉体的生产可以分为干法和湿法两种。干法生产过程中粉尘和噪音较大,产品质量控制难度大,因此此种方法较少使用。湿法工艺是将锆英砂与水、助磨剂、研磨介质按一定比例加入球磨机,处于研磨介质之间的锆英砂受冲击、研磨、剪切等作用而被粉碎制备成硅酸锆粉体。湿法生产过程中质量如颗粒细度、杂质含量等容易控制,产品稳定性较好。
硅酸锆生产过程中,要将电能先转换为机械能再进而转化为破碎功。在电能转化为机械能的过程中,球磨机的有效转化率一般仅在30-40%,大多数能量被用于自身消耗。
发明内容
本发明提供一种制备超细硅酸锆的方法,克服了超细磨时高能耗过程问题。
为了实现上述目的,本发明通过以下技术方案实现:
具体技术方案为:
一种制备超细硅酸锆的方法,按照以下物料配比和参数:
锆砂加入量:5吨 ;
刚玉球加入量:25吨,其中直径3mm球石15吨、直径4mm球石5吨、直径5mm球石2.5吨、直径6mm球石2.5吨;
料浆浓度:57%-60%;
球磨机转速:30转/min;
按以上参数,球磨时间20小时。
本发明提供的一种制备超细硅酸锆的方法,克服了超细磨时高能耗过程,通过工艺优化,关键是如何缩短磨矿时间、降低磨矿能耗、提高磨矿效率,有效地降低产品的粒径,降低加工能耗。
具体实施方式
下面结合实施例对本发明的具体实施方式进行描述,以便本领域技术人员的更好的理解。
影响球磨效率的主要因素有以下几点:球磨机的转速;研磨介质填充率与研磨介质和磨矿的比值;料浆的浓度;研磨介质的直径和材质。
一种制备超细硅酸锆的方法,按照以下物料配比和参数:
锆砂加入量:5吨 ;
刚玉球加入量:25吨,其中直径3mm球石15吨、直径4mm球石5吨、直径5mm球石2.5吨、直径6mm球石2.5吨;
料浆浓度:57%-60%;
球磨机转速:30转/min;
按以上参数,球磨时间20小时,粉体颗粒细度可达到d50:0.75-0.8um、d90:0.9-1.0um。
生产实践证明该工艺具有技术参数确定合理,产品质量稳定,产量大,能耗低,直接加工成本降低等显著特点。
