　　Application of zirconia bead dye grinding

　　1. pH value of grinding slurry

　　The initial pH value of the slurry is 5.25. After 20 hours of grinding, the slurry pH using zirconium beads is 5.78, while the slurry pH using glass beads is 10.22

　　It can be seen that the use of zirconium beads can avoid a significant increase in the pH value of dye slurry, which can have varying degrees of negative effects on the further processing and future application of dyes. The advantages of zirconium beads come from their chemical composition, high strength, and wear resistance.

　　2. Viscosity of slurry

　　After a long period of grinding, we found that the viscosity of the slurry ground with glass beads has significantly increased Under the same grinding conditions, the increase in viscosity of it is 1-4 times that of zirconium beads.

　　The main reason for the increase in viscosity of grinding slurry is the evaporation of moisture caused by the heat generated during grinding The establishment of a slurry dispersion system and the wear of grinding media (such as glass beads or zirconium beads) into the slurry can cause an increase in the dryness of the slurry with a certain solid content during the grinding process of dispersed dyes and reducing dyes. This will be detrimental to the kinetic energy transfer of the grinding media and significantly reduce the grinding efficiency.

　　3 beads stained with color

　　Dyes will stain the grinding medium during grinding. In production and testing, the ideal grinding medium should be stained as little as possible. This performance has significantly different jue values for different dyes. But if several dispersed dyes are used to grind glass beads and zirconium beads separately, after full grinding, the glass beads and zirconium beads are washed with water and dried, and then the quantified glass beads and zirconium beads are treated to compare the optical density values of the measured liquid. We can observe that The staining of glass beads is 15 to 30 times that of zirconium beads.. The application characteristics of zirconium beads are also due to their high mechanical strength and smooth surface.

　　Wear and tear of 4 beads

　　Under normal grinding conditions, zirconium beads and glass beads are used as grinding media, and after grinding is completed Measure the weight loss percentage of the grinding medium separately to evaluate the wear of the beads. After multiple experiments, we found that the wear rate of zirconium beads is less than 1/5 of that of glass beads.

　　The wear and tear of beads not only increases production costs It also increases the gray in the dye due to its chemical composition, high strength, and wear resistance.

　　5 Grinding efficiency

　　Compared to glass beads, zirconium beads have the characteristics of higher density and strength. In our application, we found that for slurries with high solid content and viscosity, using zirconium beads can significantly improve grinding efficiency; If glass beads are used at this time, it will significantly reduce the grinding efficiency, increase the grinding time, and sometimes even make grinding impossible.

　　6 Grinding Xiao fruit

　　The purpose of grinding and processing dispersed and reduced dyes is to obtain dyes with particle diameters between 0.2 and 0.8 μ m. We used zirconium beads and glass beads separately in the experiment and found that the particle distribution of the dye was much better when grinding with zirconium beads than with glass beads.
