About photoluminescent inkjet paper

The ideal superior photo quality glossy paper for digital photos and color print-outs Most suitable for high-resolution printers. Photo quality printing in dazzling and strongly contrasting. Excellent ink absorption, quick drying, perfect reproduction of small characters, more real and clear. Photo quality printing in dazzling and glowing in the dark. Directions for use Do not touch the printable side of paper. Moisture and oil from your skin can affect print quality. Hold paper by the edges. Only suitable for ink...

Phosphorescent Injection Molding Recommendations

Avoid exposing product to strong acids and or heavy metal compounds as they will react with the glow component and destroy the phosphorescent effect. Keep Moisture content of product to a minimum. Moisture content should be no greater than 00.05 – 0.10%. Minimum Drying time should be 2- 4 hours at 180℉(Fahrenheit) in either a dehumidifier or hopper dryer. It is recommended that a dew point of -20℉(Fahrenheit)   be achieved for the inlet air Phosphorescent master batches or compound material...

Experiment of preparing long afterglow materials by combustion method

Experiment part: Objective: Learn to use the combustion method to rapidly grow the afterglow materials. Understand long afterglow material and its long afterglow principle. Learn to rapidly synthesize inorganic oxides and nanomaterials by combustion method. The synthesis method of long afterglow materials and the related steps of combustion synthesis experiment Experiment principle: Combustion is also called self - propagating high - temperature synthesis. It is a kind of chemical system with high exothermic heat induced local chemical ignition through external energy, forming frontier...

Contrast of zinc sulfide and strontium aluminate phosphor luminescent powder

What is traditional Zinc Sulphide pigment? Some of the first phosphors to be developed were inorganic zinc sulphide compounds. (German submarine commanders during World War I reportedly rubbed these compounds on their hands to read documents during blackout conditions.) These phosphors typically absorb energy from deep blue and ultraviolet light and emit it as yellow-green light.This is useful in that the peak spectral distribution of the emitted light roughly coincides with the peak spectral sensitivity of the human visual system...

Photoluminescent Pigment Production Technic Process

Phosphor is a special crystal structure luminescent material, which has a strong absorbance - STORING - luminous ability, when illuminated by natural light and the light, that part of the light energy is absorbed and stored, and then in the form of visible light in the dark Slowly release the luminescent material after five minutes after the light in the dark can automatically light for more than 12 hours of light absorption process can be repeated countless times glowing,...

Photo luminescent pigment important function in industry

With the photoluminescent pigment in the handicraft industry and the toy industry applications, the use of innovative design, reasonable selection, fine production, in order to a better understanding of the relevant knowledge, and we explain below small explain luminous powder in industry Application: Now more and more customers start using photoluminescent pigment to change the performance of their products, but many of its own characteristics photoluminescent pigment is most customers do not know, for example, there are a variety of...
