Inquire

When using zirconia beads, there are many things to pay attention to. In order to ensure the grinding efficiency and smooth grinding of products, it is necessary to select appropriate zirconia beads, pre grind and clean zirconia beads. The following will introduce the precautions of zirconia beads in use.

1、 Confirm zirconia beads are suitable 

The selection of zirconia beads is a key step. Zirconia beads have different hardness, surface smoothness, particle size distribution, abrasion, chemical properties and other characteristics. Therefore, it is necessary to select appropriate zirconia beads according to the type of grinding material and target particle size, combined with the target particle size.

2、 Pre grinding

When using zirconia beads for the first time, it is necessary to put zirconia beads in a slurry with a certain viscosity for pre grinding for 30 minutes. If the slurry concentration is relatively low, it is necessary to reduce the rotation speed, and the time should not exceed 15 minutes.

3、 Cleaning

When grinding the paint, it is better to clean the zirconia beads with resin. It is recommended to clean the zirconia beads intermittently, that is, close and start again after a period of time.

4、 Supplement zirconia beads

After a period of grinding, zirconia beads will collide with each other, resulting in wear of zirconia beads. At this time, the crushed zirconia beads should be screened out with a screen, and then the zirconia beads with the same weight as the crushed zirconia beads should be put in.
