Application of photoluminescent powder proportioning

Photoluminescent powder is more and more widely used, new luminescent materials can be used in a variety of transparent or translucent media, such as plastic, silicone rubber, POLY resin, paint, glaze, ink, chemical fiber, etc. It can be used to prepare toys, craft ornaments, silica gel bracelets, artificial flowers, display objects at night and so on. The following is the application of Photoluminescent powder proportioning.

1, the proportion of Photoluminescent powder and plastic material is generally in 2%-10%. According to the color of the product, less light color, more dark color. Too much glow-in-the dark powder will make it brittle during injection molding.

2, glow-in-the-dark powder for coating is generally in 10%-50%, the more the effect is better, pay attention not to exceed 1:1 ratio.

3, the selection of Photoluminescent powder with smaller particles under 300 mesh luminous powder effect is good. Selection of lubricants polyoleic hydrocarbons (such as PE, PP) resin should be selected stearate amide as lubricant, the amount of resin 0. 2%. Abs, PS, PC, AS, PMMA and other resins choose stearate amide as lubricant, the amount of resin is 0. 5%-3%, usually 1%.

4, for polyolefin resin can be added 0. 6% antioxidant, and the synergistic effect of at168 and at1010 antioxidant. For ABS resin can also be appropriate to add antioxidant, adding amount can be less than 0. 6%.

5, the selection of plastic can choose powder, and the higher the melting index, the better. Because the resin melt index is higher, the more can give full play to the role of luminescent materials.
