Zirconia Ball with Low Porosity for Preventing Material Absorption During Grinding Processes

2025-10-27

在化工、陶瓷、新能源等工业领域的研磨环节,物料吸附现象常导致研磨效率下降、物料纯度降低及设备维护成本增加。传统研磨介质因表面孔隙或化学活性,易使物料在其表面附着残留,成为制约工艺优化的突出问题。低孔隙率氧化锆球作为新型研磨填料,凭借其独特的材料设计与性能优势,有效破解了这一难题,成为提升研磨工艺稳定性与经济性的重要选择。



低孔隙率设计:从源头减少吸附位点

低孔隙率氧化锆球的核心优势在于其微观结构的精准调控。通过先进的干压成型与高温烧结工艺,产品将孔隙率严格控制在2%-3%的极低范围,远低于普通陶瓷或金属研磨介质。这种致密的微观结构大幅减少了表面吸附位点,使物料分子难以在其表面附着或渗透。同时,氧化锆本身的化学惰性确保了表面光滑无活性基团,与极性、非极性等不同性质物料均不发生强相互作用,从根本上抑制了物料吸附的发生,保障研磨后介质表面洁净如新。

高硬度与耐磨性:保障长期稳定运行

该产品采用高纯度氧化锆原料,经特殊工艺烧结形成稳定的四方晶相结构,莫氏硬度达8.5,硬度仅次于金刚石,远超传统氧化铝球(莫氏硬度9级以下)。在研磨过程中,即便承受高频冲击与摩擦,球体仍能保持优异的结构稳定性,不易发生破碎或磨损。这种高耐磨性避免了因介质磨损产生的微小颗粒混入物料,而这些颗粒往往会成为新的吸附中心,加剧物料吸附问题。长期使用中,低孔隙率氧化锆球始终维持初始的致密结构,持续发挥防吸附作用,延长设备运行周期,降低更换成本。

化工行业应用:提升研磨工艺综合效益

目前,低孔隙率氧化锆球已在涂料、陶瓷浆料、锂电池材料、电子陶瓷等领域得到广泛应用。在涂料生产中,颜料与树脂的研磨若存在吸附问题,会导致色浆分散不均、光泽度下降,而使用该产品后,颜料颗粒分散更均匀,研磨时间缩短25%,且无物料残留,提升了涂料的稳定性与质量;在锂电池正极材料研磨中,其低吸附特性可有效避免物料因吸附导致的粒径分布异常,保障电极性能一致性;在陶瓷浆料研磨中,能减少杂质引入,提高浆料纯度,降低后续烧制缺陷率。综合来看,该产品通过降低物料损耗、提升研磨效率、延长设备寿命,为化工企业带来显著的降本增效价值。
