1. Look at the wear of zirconia beads
Put the zirconia bead sample into the grinding machine for self-grinding. Using the controlled variable method, put the two zirconia beads into the same environment for grinding, and the time and machine parameters remain unchanged. Finally, the wear data of the two zirconia beads are obtained. , The comparison result shows the difference.
2. Smoothness
The zirconia beads of good quality have relatively good performance in smoothness and roundness, and the precision of screening directly affects the particle size distribution of the zirconia beads.
3. Appearance
The color of the zirconia beads can be observed visually. Some zirconia beads have mixed colors. In this case, different colors may have different properties. After understanding, one supplier has experienced yellow and white color mixing. , We separated the two colors of zirconia beads for experiments and found that the hardness of the two zirconia beads is different, and the white zirconia beads have a higher hardness.
Zirconia beads with a smooth surface can reflect light, so the quality of zirconia beads can be judged by the degree of reflectance. In addition, some zirconia beads with a relatively large particle size can be easily seen with flaws, so the appearance of the zirconia beads can be preliminarily judged quality.
4. Internal situation
If the inside and outside of the zirconia beads are consistent, a better grinding effect can be ensured. Some zirconia beads will appear hollow inside. If the zirconia beads are uniform inside and outside, they are difficult to break during the grinding process. If the zirconia beads are broken, there is a chance If it is too large, it will cause damage to the equipment. At the same time, the wear of the zirconia beads will be very high, which will eventually lead to high grinding costs.
5. Reference parameter table
Each zirconia bead manufacturer will have a product parameter table as a reference. You can compare the parameters of your own products with the parameter table provided by the manufacturer to compare the pros and cons of their own products, and then see if it is necessary to purchase samples for further testing.
6. Quality of raw materials
Good zirconia bead materials can often be made into good quality zirconia beads. The fineness of the raw materials directly affects the smoothness, hardness and wear resistance of the finished zirconia beads, and ultimately affects the cost performance.
