glow in the dark tape electroluminescent principle

One plastic light-emitting light-emitting principle agents are crystalline phosphor or π electron organic coloring substances , they are due to the transition of electrons generated by realglow gravels for sales after excitation . Similar light-emitting materials with photoluminescence , electroluminescence mechanism of general polymer mainly in the electricity, respectively, from the positive and negative injected holes and electrons migrate these two carriers occur in the electric field , which in the polymer exciton complexes into one place , then the occurrence of exciton luminescence decay . Exciton luminescence process can be divided into exciton formation and decay realglow yellow green steps , which injected carriers ( electrons and holes ) through migration within the polymer semiconductor encounter, or the formation of singlet excitons triplet excitons , singlet exciton recombination radiation decay by emitting photons, triplet exciton energy ratio due to its much lower singlet excitons , which decay basic non- radiation. EL wire is extruded layer of the outer conductor luminous light-emitting materials , the insulated conductors realglow blue green copper or high -intensity tightly twisted together. In use, the inner conductor is energized , the outer conductor is grounded, a potential difference exists on such an insulating material , these two carriers migrate in the electric field occur , they are combined into excitons in a polymer , and then the exciton decay occurs and light.

glow in the dark tape surrounding environment

Traditional fluorescent coating materials can be divided into self-luminous and phosphorescent two. Self-luminous fluorescent agents are mostly carried by its own trace of radioactive material realglow pigments in paint ray excited luminescence fluorescent agent . The storage agent is basically fluorescent light does not contain radioactive materials , but requires advance and reserve sufficient strength to absorb external light, the electrons from their high energy level to a lower energy level transitions and stored . When darkness surrounding environment , and then gradually slow release realglow decorative stone absorption of energy from the high energy level at this time electronic transitions to the low-level , fluorescent agents began to glow. Because of photoluminescent material itself does not carry ray excitation , so the degree of temporary inferior afterglow lasting self-luminous .

glow in the dark material in the production

Since the electrons are bound by the trap at ambient temperature disturbance gradually out of the trap , the light-emitting performance of a long process , thereby forming a long afterglow . realglow decorative stone in the production , should choose ; afterglow luminous powder , luminous powder luminous green varieties can be selected ; luminous white luminous yellow green realglow stone gravel and green luminous sky blue luminous . Because there is no other color luminous powder luminous powder brightness over . So try to use caution.

glow in the dark pebbles inhalation of tritium

Containing material is generally present excitation tritium (3H or T), promethium (Pm) and radioactive radium sulfate (Ra) , fluorescent agents and fluorescent agents , mostly zinc sulfide, strontium sulfide , calcium or zinc , and other alkylene sulfates. Tritium realglow glow in the dark pigments and promethium (Pm) , though still radioactive , but the potential damage to the human body is much smaller. Tritium (3H or T) is an isotope of hydrogen , the nucleus consists of a proton and two neutrons , with radioactivity occurs β decay half-life of 12.43 years . Although tritium photoluminescent pigment suppliers also manufacture thermonuclear weapons , but its β decay will release the fast-moving electrons, does not penetrate the human body, only a lot of contact with and inhalation of tritium (3H or T) will cause the human body injury.

glow in the dark pebbles and technology

In addition , with tritium (3H or T) similar fluorescence excitation radioactive agents there promethium (Pm), the half-life of 17.7 years . Since the 1990s, with the development and progress of science and technology , the emergence of new storage afterglow light rare glow pigment powders  alkaline earth aluminate phosphor material does not contain radioactive material. It differs from the traditional nature of the sulfide -and radiation- excited type luminous material , completely free of any harmful elements , chemically more stable, high brightness, long afterglow time . Long-lasting storage realglow photoluminescent paint suppliers is a light-induced luminescence (Photoluminescence) material by ambient light , such as any kind of daylight , lighting and other energy excitation .

There are three main glow in the dark stones

 First, the current impact of the European debt crisis is still the continuation of debt recovery and development of the manufacturing sector will take time , domestic housing market is still sluggish , on the iron market will have a direct impact ; second , affected by domestic realglow photoluminescent exit signs , rising energy prices , the slowdown in the steel industry , the material needed for the production of iron oxide reduction in scrap metal , will result in raw material prices . Coal , electricity and driveway gravels prices and acid, alkali and other chemical products prices, will make the product costs continue to increase ; Third , continue to release new capacity in the return of U.S. manufacturing background , some domestic companies are realglow photoluminescent paint suppliers , expanded production projects . The new incremental continue to gush , making it difficult to fall in business inventories , short-term domestic and foreign markets is difficult to recover, market competition will continue to intensify.

glow in the dark material particle size

However, due to the specific gravity of 4.1 luminescent pigment particle size is 19 --- 25um, it is necessary to be made ??of synthetic resin granules or pellets, and then used in processing . Standard ratio storing pigment incorporated into the resin is 10 to 20% by weight --- . The higher the amount of the phosphorescent pigment is realglow where to buy glow powder in the brightness . The ratio can be set depending on a use , cost, and other conditions . Phosphorescent pigment is the main component of the phosphor ZnS (ZnS: Cu). Avoid the use of resins and additives containing lead, cadmium , iron and other heavy metal ingredients. Since the phosphorescent pigment is pigments in paint a high temperature close to 1300 ℃ , so its thermal stability is relatively high . However, if they contain heavy metals described earlier , when there may be heat molded suffered accelerate its deterioration. In addition, the high acid value , then , over time , luminescent pigment will degenerate.

The higher the content of glow in the dark film

The phosphorescent pigment content of the aqueous ink luminous , the higher the light emission luminance of the ink printed pattern , the longer the light emission time . Luminous pigment can not grind ,Realglow luminous masterbatch pe plastic containers or glass, driveway stone container with high-speed dispersion stirring.Do not use a heavy metal compound additives .Depending on the selection of different types of substrates and transparent ink formulation . Such as: metal substrate material should be used in metallic ink , driveway stone should be selected for the pvc pvc ink. Luminous ink for use:    Ink viscosity of about 3000-5000 cps.    When printing, the printing speed according diluent to adjust the ink viscosity.

 Polymer electroluminescent material also has a number of advantages can be applied to various fields of industry sectors . realglow glow in the dark pigments wire and cable manufacturing, using its luminescent properties, you can create an alert or have decorative products . Environments such as airports , decorative street environment. Especially in cable tunnels photoluminescent pigment suppliers external light source , electroluminescent products to better show its "active " feature.
