Configuration and Usage Instructions for Luminescent Plastics

1. Selection of resin:
It is preferable to use powdered resin and one with a slightly higher melt index.
2. Selection of luminescent pigments:
Type C or D are more effective. If the particle size is too large or too small, dispersion will be poor.
3. Selection of lubricants: For polyolefin resins (such as PE and PP), stearic acid amide should be used as the lubricant.
For resins like ABS, PS, PC, AS, and PMMA, stearic acid salts should be selected, mainly including stearic acid zinc and stearic acid magnesium.
4. Selection of dispersants:
Using powdered PE wax can enhance the dispersion effect of the luminescent pigments and improve the appearance and color of the products.
5. Selection of coupling agents:
Before adding the luminescent pigments to the resin, they should be treated with a coupling agent first, and then mixed with the resin and additives. This can increase the mechanical properties of the luminescent plastic products. Titanium azide and silane compounds can both be used.
6. Selection of stabilizers:
The main stabilizers used are antioxidant types.
In terms of the process:
1. Equipment with a smaller length-to-diameter ratio should be selected. If the equipment cannot be changed, the temperature of the feeding section and the conveying section of the main machine can be appropriately increased (2-3℃ is sufficient).
2. The rotational speed of the main machine should be 15-20% higher than the normal speed to increase the running speed of the materials.
3. During the pre-mixing of the materials, do not allow the luminescent pigments to be subjected to any strong shearing and friction on high stirring machines or high mixing machines. With
At that time, when mixing the ingredients, try to use plastic or ceramic containers.
