2 . The Feature of 95 zirconia beads :
High grinding efficiency: Due to the high density of zirconium oxide balls, it has a higher grinding kinetic energy at the same moving speed, and the grinding efficiency is 2-3 times higher than that of ordinary ceramic beads. You can get better results.
Impact resistance, low wear: Due to the high content of ZrO2, high density, high toughness, low abrasion, no broken ball, peeling, etc., the dispersion of the abrasive is less polluted. The abrasion is 4-10 times lower than that of ordinary ceramic beads.
Good stability: good stability, acid and alkali corrosion resistance.
Good fluidity: good circularity, smooth surface, no pores, reflective gloss, easy to clean. The fluidity between the microbeads and the microbeads is good, and the wear on the equipment is small.
Low cost of use: Zirconium oxide ball wear is the lowest in all grinding media. Zirconium oxide balls are high-strength, inert, hard, perfect, fine spherical particles.
3 . The application scenarios of 95 zirconia beads :
1. In the field of new energy materials: In the production of lithium batteries, this bead is used for ultrafine grinding of positive electrode materials such as ternary lithium and lithium iron phosphate. By precisely controlling the particle size distribution (0.3-3.0mm optional), the positive electrode material particles can be refined to the sub micron level, improving the material's compaction density and ion conductivity, thereby enhancing battery energy density and cycle life. According to actual test data from a leading battery company, the first discharge specific capacity of the positive electrode material increased by 8% and the capacity decay rate decreased by 12% after using 95 zirconia beads.
2. High end chemical and electronic fields: In precision chemical production such as photoresist and nano coatings, this bead body, with its low wear characteristics, can avoid the introduction of metal impurities and ensure product purity meets electronic grade standards (impurity ions ≤ 10ppm). For example, in the grinding of dielectric ceramic slurry for 5G communication devices, 95 zirconia beads can control the dispersion of ceramic particles within ± 5%, ensuring the stability of dielectric constant and helping to improve the performance of high-frequency electronic components.
3. Medical and food industry fields: In the production of pharmaceutical intermediates grinding and food additives, its non-toxic and corrosion-resistant characteristics meet strict hygiene standards. After using the bead processed raw materials, a certain vitamin manufacturer improved the particle size uniformity of the product to over 99%, and the heavy metal residue was below the detection limit (<0.1ppm), successfully passing FDA certification. In addition, in the cell lysis process of biopharmaceuticals, high hardness beads can efficiently break down cell walls while avoiding damage to active ingredients by metal ions, thereby improving extraction efficiency.
