The reason why the brightness of the luminous powder is not high after injection molding

Luminous powder is a kind of luminous pigment that can emit light automatically. It can be used in various plastic products, clothing printing, chemical fibers, and indicator signs, etc. However, some customers reported that after buying the luminous powder and using it on the plastic, they found that the brightness of the luminous powder was not as good as expected, and even the situation was not bright. Today, I will analyze the reasons why the brightness of the luminous powder is not high after injection molding.

1. One of the reasons for the low brightness of luminous powder is that it may be exposed to acid, water, and metal during use, which will cause the brightness of luminous powder to be greatly reduced after the sun millet.
In order to avoid this situation, we should pay attention to the following matters when using luminous powder:
1. We should avoid using it in an acidic environment (Al2O3 will neutralize with acid).
2. Avoid contact with water, try to keep it sealed; (it will absorb moisture in the air, so that the luminous powder will turn black and not glow and agglomerate).
3. Avoid contact with metal (it will affect the unsaturated state of the luminous powder and affect the luminescence).
4. Avoid high temperature and high speed friction (it will change the existing structure of luminous powder).
2. In the injection molding process, the plastic material we use is not very transparent, which will also cause the luminous powder to not absorb light or emit light. So first weigh the luminous powder according to the proportion, add an appropriate amount of paraffin oil (diffusion oil is available), adjust it into a paste, and then pour it into the weighed rubber and mix well to produce. The materials that can be injected are: PP, PE, PVC, PU, ​​PS, ABS, TPR, EVA, PMMA, nylon, etc. The more transparent the plastic material is, the better the luminous effect.
