Metal powder can be obtained through three preparation methods.
The following table is the three different methods and the differences between them:
| Method | Squeeze out | Dry mix | Bonding |
|
Difference |
• The color will be dim • Addition limit • Special effects(coarse texture) |
• Easy to implement and small investment • Construction is difficult, when the high proportions • Recycled powder is not easy to control,Easy to produce chromatic aberration |
• High construction requirements and large investment • Easy to control construction • High recycling rate and controllable color difference |
principle:
The temperature of the base material mixture is increased by mechanical method frictional heat generation,
which is slightly lower than the glass transit temperature of the resin, and then a metal pigment (such as aluminum powder) is added,
after holding for a certain period of time, the bonding effect of the material is generated,
which results in a bonding effect, as shown in the following reaction picture:
