1. Use powdered luminescent powder, and the higher the melt index, the better. Because the higher the melt index of the resin, the more it can fully play the role of the luminescent material.

2. The selection of luminous material luminous powder: the effect of the smaller luminous powder below 300 mesh.

3. Process: The equipment with a relatively small length and diameter 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 degrees). The rotation speed of the main engine should be 15% to 20% higher than the rotation speed under normal conditions to increase the material running speed. When the materials are premixed, do not allow the long-lasting luminescent powder to be subjected to any strong shear and friction on the high mixer and high mixer. At the same time, ceramic or plastic containers should be used as much as possible when mixing

4. Lubricant selection: Polyester hydrocarbon (such as PE, PP) resin should use stearic acid amide as the lubricant, and the amount is 0.2% of the resin.

For ABS, PS, PC, AS, PMMA and other resins, stearic acid amide is used as the lubricant, and the amount is 0.5%-3% of the resin,--generally 1%.

5. Selection of dispersant: Choose powdered PE wax to improve the dispersion effect of Yaodexing's luminescent powder and improve the appearance and color of the product.
