Jade-like stone light rare earth long-term Photoluminescent Film producing plastic pigment factory belongs to the type alkaline earth aluminate long afterglow luminescence materials, components can be expressed as: Al2O3 · (Sr, Mg, Ca) O: (Eu, La, Dy) B, can be in the sun or light absorbance 5-20 minutes later, will absorb the light energy stored in the crystal lattice, after can convert the energy into light energy in the dark and light, which can effectively sustained glow (luminescence brightness is more than 10 MCD/m2) to 8 to 16 hours, Photoluminescent intensity attenuation to the lower limit of the human eye observation (0. 32mcd/m2) can be up to more than 70 hours, stable chemical properties, light absorption, storage, luminescence process can be repeated, the service life of up to 20 years. This company produces the long effect Photoluminescent Film non-toxic harmless does not have the radioactivity, the brightness is high, the luminescence time is long, the afterglow time is long, the price is cheap, the quality is stable, welcome to inquire to order!
Huizhou jade-like stone light plastic pigment factory production of noctilucent Film because of the above characteristics, so that it can be widely used in many different fields, can be made into coating, silica gel, printing ink, plastic, rubber, paper, film, etc., the application of safety in consumer goods, such as: in the clothing, shoes and hats, stationery, watches and clocks, switches, panels, fishing paraphernalia, decorations, crafts and sports goods, in architecture decoration, transportation, military installations, fire emergency system, such as: The sign indicating system of entrance sign, escape sign and lifesaving route has a good and reliable function.
Main technical indexes of glistening long-acting Photoluminescent Film:
A. The main ingredients of this product are: strontium aluminate (SrO) ·(MgO)0. 1 · Al2O3 (EuO, Dy2O3) 0. 01 b.
- Specific gravity of long-acting Photoluminescent Film
The density of the product is 3.4-3.6, and the bulk density is about 1.5-3.5, different models are different
- Long-acting Photoluminescent Film process
The main manufacturing processes of this product are: purification of raw materials, batching, sintering, crushing, grading, testing, packaging and so on.
Four. Long – term Photoluminescent Film excitation and emission wavelength: visible light.
Five. Measure the afterglow of night glower
(see product standard)
Six. Long Photoluminescent Film excitation time
Under different illuminations, the excitation time required is different. Under D65 illumination of 500-1000lux, the time required is about 15-30 minutes. Different types of products are also slightly different.
Seven. Long-term Photoluminescent Film light resistance
No significant change was observed for 200 hours under daily strong light and ultraviolet light.
Eight. Long-term Photoluminescent Film water resistance
The untreated Photoluminescent product was immersed in water for 1 hour without obvious change, and then it was hydrolyzed gradually and oxidized with europium bivalent, turning white and losing its afterglow characteristics. (different models have slightly different water resistance time).
(blue light and red noctilucent Film belong to another system, and immersion water does not change the Photoluminescent performance.)
Nine. Long-acting Photoluminescent Film radioactivity
By the relevant state departments testing, non – radioactive, non – toxic.
Ten. Heat resistance of long-acting Photoluminescent paper Film
The oxidation atmosphere of 800K for 0.5 h showed no obvious change in performance.
800K oxidation atmosphere for 0.5 h, with the increase of temperature, the performance decreased significantly. > 1273K, almost no residual luminescence 0-1600k reduction atmosphere 0.5 hours, no significant change in performance.
