How to use colored luminous powder?

The ability of the colored luminescent powder to absorb radiation is related to the degree of dispersion of the phosphor, so the size of the granule has a great influence on the luminescence brightness. The particle size of the calcium halophosphate phosphor is determined by the particle size of the raw material CaHPO4. Therefore, by obtaining the crystal CaHPO4 of the necessary size and crystal lattice, the particle size of the color luminous powder can be controlled to a certain size (5 to 10 μ), so the invention of reading high is obtained. brightness. Among the rare earth trichromatic phosphors, yttrium activated yttrium oxide (Y2O3:Eu), green powder is lanthanum and cerium activated aluminate (MgAl11O19:Ce, Tb), and blue powder is low yttrium activated yttrium magnesium aluminate ( BaMg2Al16O27: Eu).

In order to allow the color luminous powder to be fully integrated into the material to select the lubricant is a good choice, PP, PE resin can choose ammonium stearate, the amount of about 0.2% of the resin. Some manufacturers will also add some PE wax to improve the smoothness of the color luminous powder, and the dispersion effect is also good. If it is a luminescent pigment, adding a coupling agent and a resin mixture can add brightness and mechanical properties. The amount may be 1.3% or 1.5% of the pigment, and the equipment used in the process is slightly smaller in length. When stirring the substance mixed with the luminescent powder, pay attention to the strength and avoid excessive friction.

How to use color luminous powder 1, short excitation time, long time of luminescence and afterglow, high brightness. 2, extremely stable physical and chemical properties, strong environmental adaptability, and ordinary service life. 3, safe and reliable, energy saving, green and environmental protection. 4. The particles are small, the fineness and the particle size distribution are uniform. Color luminous powder equipment: electric furnace, crucible, ball mill, drying equipment. Formula: Red luminous powder: 55 g of barium sulfate, 40 g of magnesium sulfate, 2 g of lithium phosphate, 3 g of copper luminous powder: 63 g of calcium sulfide, 5 g of sodium sulfate, 5 g of potassium sulfate, 10 g of barium sulfate, chlorine Sodium 6 g, silver 1 g, magnesium sulfide 10 g.
