Description

一种陶瓷粉末球磨混料罐及其使用方法
技术领域
本发明属于工业陶瓷加工领域，具体涉及一种陶瓷粉末球磨混料罐及其使用方法。
背景技术
陶瓷的高强度、高硬度、高弹性模量以及热化学性稳定等优异性能是使其成为众多学者研究的热点复合材料之一，如氧化铝、氧化锆的陶瓷粉末，可以用于生产手机背板。陶瓷粉末的制备一直是工业陶瓷生产的重要环节，陶瓷粉末的制造效率以及质量都会直接影响工业陶瓷产品的生产质量以及生产效率。球磨是利用利用研磨体，如钢球的冲击作用以及研磨体与球磨内壁的研磨作用而将物料粉碎并混合。当球磨转动时，由于研磨体与球磨内壁之间的摩擦作用，将研磨体依旋转的方向带上后再落下，这样物料就连续不断地被粉碎。
现有球磨混料罐由罐体和封盖组成，封盖通过连接件与罐体形成紧连接，在罐体和封盖的内部形成一个内腔，球磨混料罐由难熔金属的硬质化合物和粘结金属通过粉末冶金工艺制成。具有硬度高、耐磨、强度高，韧性好，耐热耐腐蚀等一系列优点。其中高硬度和高耐磨性尤其突出，即使在500℃的温度下也基本保持不变。硬质合金球磨混料罐应用在行星球磨机中，配硬质合金磨球，用于研磨硬质合金粉末、金刚石，金刚砂等高硬度粉末。
现有的球磨混料罐存在以下不足：
1、罐体内为标准圆柱内腔，存在无法研磨的死角，造成研磨不充分，罐底为平面，球磨球与陶瓷颗粒为点接触，研磨效率欠佳；
2、罐体和封盖接触面容易使混料粉末泄露，造成行星式球磨机损坏。
发明内容
针对现有技术所存在的上述不足，本发明的目的是提供一种陶瓷粉末球磨混料罐及其使用方法，提升研磨效率和质量，避免陶瓷粉末的泄露。
为了实现上述目的，本发明提供一种陶瓷粉末球磨混料罐，包括罐体、封盖，所述封盖包括突起的柱塞，柱塞伸入罐体内部，封盖使罐体保持内腔密闭，所述罐体内放置有多种直径的球磨球，
所述罐体、封盖、球磨球采用氮化硅材料，所述罐体的侧壁与底部设置有倒圆，所述罐体底部内侧均匀设置有多个弧形凹坑，所述弧形凹坑之间通过圆角过渡，
所述封盖外圈底部设置有台阶，所述罐体顶部也设置有台阶，组成第一接触面、第二接触面，所述第一接触面和第二接触面之间设置有空腔，所述第一接触面、第二接触面分别设置有沟槽，沟槽内填充密封圈。
进一步地，所述球磨球选择半径1mm、半径2.5mm与半径5mm的小球。
进一步地，所述倒圆半径大于5mm。
相应地，提供一种陶瓷粉末球磨混料罐的使用方法，包括以下步骤：
S1.称量原料：参照已设计的配方，使用型号为精密天平称量所需原料，严格按照所设计配方数据称量，过程中需要保证实验台和天平的干净整洁，门窗处于关闭状态，以免造成数据误差；
S2.球磨混料：打开封盖，按照球料比，选择合适数量和规格的球磨球放入罐体中，
S3.陶瓷混料：按照配方组成称取适量主料、氧化钙、氧化镁、氧化硅、碳酸钠，加入适量氧化镧和氧化锰为着色添加剂，加入球磨罐中；
S4.按照配方组成加入适量的酒精与粘结剂，搅拌混合均匀；
S5.调整两个密封圈的安装，关闭封盖；
S6.将球磨罐放入行星式球磨机中球磨10小时以上。
进一步地，所述主料为氧化铝或氧化锆。
本发明的有益效果：
1、本发明所述的陶瓷粉末球磨混料罐和球磨球，采用氮化硅材料制成，在不同浓度、不同温度的有机酸和无机酸中，尤其是在氧化性介质中具有良好的耐磨蚀性能，同时具有优异的高温应力破断性能及高温抗蠕变性能，适用于氧化铝和氧化锆。
2、罐壁和罐底采用倒圆过渡，避免球磨混料罐中存在无法研磨到的死角，防止研磨不充分，同时设置弧形凹坑，增大球磨球和陶瓷颗粒的接触面积，提高研磨效率；
3、球磨混料罐设置有双层密封，避免混料粉末的泄露。
