技术领域technical field
本发明属于研磨介质技术领域，具体涉及一种耐磨硅酸锆介质球及其制备方法。The invention belongs to the technical field of grinding media, and in particular relates to a wear-resistant zirconium silicate media ball and a preparation method thereof.
背景技术Background technique
研磨介质球因其具有高强度、高硬度、耐磨、耐腐蚀的特性，现作为研磨介质被广泛应用于陶瓷、电子、建材、新材料等领域。现有技术的陶瓷球通常采用等静压成型的方式制成，例如：《材料导报》2000年10月第14卷专辑，贾光耀、张伟儒等《低成本氧化锆研磨球的研制》公开了一种研磨介质的制法，采用湿法球磨及喷雾造粒制备超细粉体，然后在0.1～0.16GPa压力下采用冷等静压成型，最后经过高温烧成制备氧化锆研磨球，其公开的内容引用于此。Due to its high strength, high hardness, wear resistance and corrosion resistance, grinding media balls are widely used as grinding media in ceramics, electronics, building materials, new materials and other fields. Ceramic balls in the prior art are usually made by isostatic pressing. For example, in the 14th volume album of "Materials Herald" in October 2000, Jia Guangyao, Zhang Weiru, etc. "The Development of Low-Cost Zirconia Grinding Balls" disclosed a A grinding medium preparation method, using wet ball milling and spray granulation to prepare ultra-fine powder, then adopting cold isostatic pressing under a pressure of 0.1 to 0.16GPa to form, and finally firing at a high temperature to prepare zirconia grinding balls, which is disclosed The content is cited here.
现有技术中的滚球成型方法，一般是将超细粉体原料泥浆挤出切断造粒，然后滚动成型，其存在的缺点是：1）该方法需要的设备多，一次性投入大；2）该方法操作复杂，且由于制得的种球粒径均一性不佳，导致滚动时间越长，陶瓷球的粒径差别越大，从而使该方法只适用于小粒径陶瓷球的制备，特别适用于小于8mm陶瓷球。The rolling ball forming method in the prior art is generally to extrude the ultrafine powder raw material slurry, cut off and granulate, and then roll forming. The disadvantages are: 1) This method requires a lot of equipment and a large one-time investment; 2. ) This method is complicated to operate, and due to the poor particle size uniformity of the prepared seed balls, the longer the rolling time, the greater the difference in particle size of the ceramic balls, so that this method is only suitable for the preparation of small particle size ceramic balls. Especially suitable for ceramic balls smaller than 8mm.
