What Should We Pay Attention To When Using Zirconia Beads? 80% Of People Do Not Fully Play Its Role

1、 Confirm whether zirconia beads are suitable

Selecting zirconia beads is a key step. Zirconia beads have different hardness, surface smoothness, particle size distribution, wear, chemical properties (do not react with materials), etc. Therefore, appropriate zirconia beads should be selected according to the type and target particle size of their own grinding materials and the target particle size of grinding.

2、 Pre grinding

When using zirconia beads for the first time, it is necessary to pre grind zirconia beads in slurry with certain viscosity for 30 minutes. If the slurry concentration is relatively low, reduce the rotating speed, and then the time shall not exceed 15 minutes.

3、 Clean

When grinding paint, it is best to take resin to clean zirconia beads. If solvent is to be used, reduce the speed, and the time shall not exceed 10 minutes. It is recommended to clean zirconia beads intermittently, and then shut down and restart after starting the machine for a period of time.

4、 Catch up

After grinding for a period of time, zirconia beads will collide with each other, resulting in wear of zirconia beads. Therefore, after using for a period of time, some zirconia beads need to be added as supplement. Note that before supplement, the broken zirconia beads should be screened off with a screen, and then put in zirconia beads with the same weight as the broken zirconia beads.

5、 Other time to make up the ball

If the grinding time is prolonged or the grinding fineness cannot achieve the desired effect under the condition that the grinding fineness requirements remain unchanged, a certain amount of zirconia beads need to be added
