Composition and luminous phosphors What are the main ingredients

First, the main composition and characteristics of luminous;
1. Material ingredient statements luminous mixture 4SrO.7AL2O3: Eu (Eu for rare earth elements).
2. The most important non-toxic non-radioactive luminous, no burning, no explosion, without other harmful heavy metals or chemicals.
3. powdered paint pigments with a very stable physical and chemical properties, strong environmental adaptability and extremely long service life, the effect can be achieved using the longest 20 years. The density of luminous ρ≈3.6gcm3 7. maintain good stability under conditions of -60 ℃ -600 ℃.
The luminous STORING short time, high brightness, long afterglow time, rich color variety, color and more.
5. luminous powder can be used as an additive or a pigment. Evenly distributed in a variety of transparent or translucent medium, such as paint, oil, black, plastic, rubber, printing glass, ceramics, chemical composition, to achieve self-stones for driveway media functions, showing a good indication of low lighting and decorative landscaping should effect. The crystalline structure of the material has a stable luminescent properties under the premise of the crystal structure can not be destroyed permanently extinction - Storage - light, performance in general life of up to 20 years. The material is in the range of -20 ℃ -1080 ℃. Luminescent properties of fundamental change. 300W high pressure mercury lamp at 1000 hours, no change of character and luminescent properties so you can use outdoors.
Second, the composition and characteristics of the phosphor;
1. Phosphor good heat resistance: maximum temperature of 600amp # 176C, suitable for high-temperature processing of various treatments. Good solvent resistance, acid, alkali, high stability. No color shift (MIGRATION), does not pollute.
2. Phosphor non-toxic, does not overflow when heated formalin (FORMALDEHYDE), can be used on colored toys and food containers. Color body will not overflow, when in the injection molding machine for mold, you can save cleaning procedures.
3. Fluorescence bright color, good hiding power (opacity can be added free agent).
Fine spherical particles, easily dispersed, 98% of the diameter of about 1-10u.
4. Phosphor plastic injection and extrusion of the application:
Applicable to a variety of plastics such as PE, PS, PP, ABS, acrylic, urea, melamine, polyester, resin, the fluorescent color. Recommended dosage of 0.05% to 0.5%, usually 0.05-0.1%, compounding should add a certain percentage of additives to enhance its stability and oxidation resistance
