Effect of the selection of zirconia beads on grinding:
1. The hardness of zirconia beads. Generally, the higher the hardness of the zirconia beads, the lower the abrasion resistance of the beads. From the perspective of the wear of the zirconia beads on the contact parts of the grinding machine, The wear of the contact is slightly larger, but the bead with smooth surface wears relatively little to the barrel and the grinding disc. At the same time, the parameters such as the filling amount of the grinding beads and the viscosity and flow of the material can be adjusted to achieve a better optimization point.
Second, the density, the higher the density of zirconia beads, the greater the kinetic energy generated by the rotation of the grinder, the higher the grinding efficiency, but on the other hand the greater the density of the grinding medium contact (grinding the inner cavity wall, grinding Disk, etc.) wear is relatively large, so the viscosity and flow of the material become the key. Low density zirconia beads are suitable for low viscosity materials, and high density zirconia beads are suitable for high viscosity materials.
Precautions for using zirconia beads:
First, according to the viscosity, hardness, grinding size and grinding requirements of the grinding material, select the corresponding variety, size and number of zirconium beads;
Second, before grinding, clean the zirconium beads and the inner wall of the grinder barrel;
3. Put the material to be ground into the barrel of the grinder first, and then put the appropriate amount of zirconium beads. After the mill was running, the zirconium beads were gradually added. The filling volume is generally 70% to 85% of the inner volume of the barrel of the grinder;
Fourth, do not let the zirconium beads run for a long time in the absence of material in the mill. Otherwise the grinder is easily damaged;
Fifth, after the mill runs for a period of time, it is necessary to replenish the zirconia beads in an appropriate amount to ensure the quality and efficiency of the grinding.
The above is how zirconia beads are used in the formation of coatings, so when you do n’t do it, don't say so simple, you won't feel that zirconia beads are just for grinding when you fight for a long time.
