Luminescent plastic configuration and instructions for use

1. Selection of resin:
Had better choose powdery form resin, with the resin with melting index a bit taller relatively.
2. Selection of luminous pigments:
Type C or D is more effective, and the particle size is too large or too small for dispersion.
3. Selection of lubricant: stearate amide should be used as lubricant for polyolefin resin (such as PE, PP).
ABS, PS, PC, AS, PMMA and other resins should choose stearate, mainly zinc stearate and magnesium stearate.
4. Selection of dispersant:
The choice of powder PE wax can improve the dispersing effect of luminous pigments and improve the appearance and color of products.
5. Selection of coupling agent:
Luminescent pigment should be treated with coupling agent before adding resin, and then mixed with resin and auxiliary agent to increase luminescence
Mechanical properties of plastic products. Both titanates and silanes are available.
6. Selection of stabilizer:
Antioxidant stabilizers are mainly used.
In the process
1. Equipment with relatively small length and diameter should be selected. If the equipment cannot be changed, the feeding section and conveying section of the host can be appropriately increased
Temperature (2-3 ℃)
2. The speed of the main engine should be 15-20% higher than that under normal conditions to improve the speed of material operation.
3. When materials are premixed, do not allow the luminous pigment to be subjected to any strong shear and friction in the high mixing machine or the high mixing machine. with
When mixing, try to use plastic or ceramic containers.
