Photoluminescent pigment (normal called noctilucent pigment/glow in the dark pigment) is a kind of luminous pigment with special crystal structure.
1 . Main classification:
The Photoluminescent Pigment usually divided into light energy storage Photoluminescent Pigment and radioactive Photoluminescent Pigment. Light energy storage Photoluminescent Pigment can store the light energy after exposuring to the natural light, solar lights, uv irradiation. And after exposuring,it will released in the form of fluorescence slowly. So at night or in the dark, you can still see the light glowing for couple to more than ten hours.
2. Material properties
1.The firing time is short, the glow time is long, and the brightness s high.
2.The physical and chemical properties are very stable , the environment adaptability is pretty good,and the service life is very long.
3.Safe ,reliable, energy saving, environmental protection.
4.The particle size is small , the fineness and particle size distribution evenly.
3. Main Application
People in normal life using long light-emitting characteristics of Photoluminescent Pigment to make the weak lighting source.
(1) Special use in military departments .
(2) Spread this kind of material on the aircraft instruments, clocks, windows, all kinds of switches on machine , the door handles.
(3) Can also compressed into various symbols, components, supplies(such as the power switch, socket, fish hook, etc.)with all kinds of transparent plastic . Those light-emitting devices after irradiation,when power outage at night or weak up after the lightning it continues shining,it can make people identify direction around.It brings a lot of convenience for people’s work and life.
(4) Adding the luminous material ultrafine particle into the textile, make the color be more bright-coloured. If kids put on the luminous fabrics, can reduce the traffic accidents.
As the application of photolumincsent pigment widely using in the Handicraft and Toy industry. More and more customers start using photolumincsent pigment to alter the performance of their products.But many features of it still unknow by most customers .Now there are many kinds of photolumincsent pigment in the market, both of the quality and the have the big difference.Many customers are hard to get thier desired photolumincsent pigment. The biggest reason is the photolumincsent pigment market still do not have the industry standard.But it different from our traditional understanding that the products with the higher price will have the better performance.Especially in the handcrafts and toys industry.The requirement of glow time is not so long. But have the higher requirements of the body color and light absorption speed .So when some users choosing the photolumincsent pigment,do not understand the one-time performance situation of some of the photolumincsent pigment .Will get some problem in using and selecting the photolumincsent pigment.So you should understand some simple properties of photolumincsent pigment , then choose the most suitable one which meet your process and requirements .
At the previous articles we have already said the problem of the response time of light absorption.This is particularly important to the application of handicraft and the toy industry.Instead,the length of glowing time be no more important at all.The Indicating industry like Signs etc. attaches great importance to the shining time.So I hope when customers selecting the photolumincsent pigment,should choose rational to the .Hope the photolumincsent pigment can give your products the wider application .
4. Attention notes:
(1) Avoid use in acidic conditions (Al2O3 will have the neutralization reaction of with acid .
(2) Avoid contact with water, seal save as far as possible; (it will absorb moisture in the air, photolumincsent pigment will get black,no longer shine and agglomerate).
(3) Avoid contact with the metal (will affect the unsaturated state of the photolumincsent pigment, effect shining).
(4) Avoid high-speed friction under the high temperature (will change the existing structure).
The radioactive photolumincsent pigment is adding the radioactive material in the fluorescent pigment, using the rays from radioactive material inspire the phosphor glows. This kind of photolumincsent pigment have a long time shine, but poisonous ,harmful and environmental pollution , so the application range is samll.
