1. The wear of zirconia beads
Put the zirconia bead sample into the grinding machine for self-grinding. Using the control variable method, put the two kinds of zirconia beads into the same environment for grinding. The parameters such as time and machine are unchanged.
Finally, the wear data of two kinds of zirconia beads are obtained, and the difference can be seen by comparing the results.
2. Smoothness
Good quality zirconia beads have better performance in terms of smoothness and roundness, and the screening accuracy directly affects the particle size distribution of zirconia beads.
3. Appearance
The color of zirconia beads can be seen 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 separate the two colors of zirconia beads and do experiments respectively and find that the hardness of the two kinds of zirconia beads is different, and the white zirconia beads have higher hardness.
Zirconia beads with smooth surface can reflect light, so the quality of zirconia beads can be judged by looking at the reflectance. In addition, some zirconia beads with larger particle size can easily see defects, so the appearance of 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 guaranteed. Some zirconia beads will appear hollow inside. If the inside and outside of the zirconia beads are uniform, it is difficult to break during the grinding process. If the zirconia beads are broken, the probability of breaking If it is too large, it will cause equipment damage, and at the same time, the wear of 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 pros and cons of your own products with the parameter table provided by the manufacturer, 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 high-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.
