APPLICATION
LED Sealing Material
Problems
- check_boxIt is difficult to mix powders such as phosphors and dispersants uniformly.
- check_boxThe materials are expensive, but improving the yield is difficult.
- check_boxMixing and defoaming process is time-consuming.
Solution
- check_boxHigh shear force enables uniform defoaming and improved performance (brightness).
- check_boxThe yield rate can be improved by non-contact manner.
- check_boxDefoaming can be done simultaneously with mixing, which shortens the processing time.
Test Result
Uniform mixing when the revolution speed is set at 1:1.
There is a few phosphor precipitates.
No phosphor precipitates.
Recommended models
2 axis 350g×2 cups
2 axis 1kg×2 cups
Independently variable revolution/rotation speed (2 axis)
Independently variable revolution and rotational ratio are advantageous for mixing materials with large differences in specific gravity, such as silicone resin/epoxy resin and phosphor.
Vacuum model
Prevents degradation in quality due to fine bubbles.
