Glow in the dark materials type

Glow in the dark materials luminescence is varied, the main types are: photoluminescence,Glow in the dark pebbles cathodoluminescence, electroluminescence, thermoluminescence, optically stimulated luminescence, radiation luminescence.glow in the dark materials and different from incandescent. Since the material but cold objects chemical reaction energy,Photoluminescent Aluminum Sheet subatomic movement or stress caused by intracrystalline radiation.
Glow in the dark materials in addition to the heat radiating material is in the form of light emitted from the excess energy, the emission process has certain duration.
Glow in the dark materials can form a powder, crystal, or amorphous thin films, such as the use of, the main component is a compound semiconductor materials and rare earth metals, a very close relationship with the non-ferrous metals.

Luminous and unsaturated polyester resin formulations

The above formulation has a poor quality of raw material problems , such as when a large amount of work , with a good first luminous paste, once a trial to identify the optimal ratio of raw materials to achieve the best results.
The first time the product is expected to produce 191 cups of the amount of the amount of resin into the container quasi then added 191 resin , 20 parts per 100 parts of luminous powder , stir together glow in the dark stone , stir well , add accelerator 1-2 parts by sufficient stirring , the above preparation process can not be reversed .Pvc construction materials in the winter may be appropriate to give a little to make it thickens some , the summer powdered paint pigments should be appropriate cyclohexanone Cadogan some thinning otherwise make poor scraping.

The material used for the signal

The material used for the signal , note writing , emergency evacuation routes , subway stations , underpasses , civil air defense projects , karaoke ok hall, dance hall, theater , supermarket stores , pp masterbatch, railway stations , airports , docks , shelter , etc., may play a role in preventing dangerous occurrence .
Three buildings : the building of the material applied to the walls , ceramic tile, the inner surface of elevators, bridges, roads , such as road signs, road studs , roadblocks , ports , outdoor advertising is not only beautiful and practical value. Other: If Crafts: amber , photoluminescent pigment, glass , painting ; toys: plastic toys , puzzles , building blocks ; clothing : hats , gloves , overalls , t-shirts , shirt, helmet , printing clothing ; calendars , fishing and so on.
4 . The best use of its long-lasting luminous scope and conditions of use, please refer to the specific luminous manual or technical advice.

Mainly because there is no industry standard yet luminous

Mainly because there is no industry standard yet luminous , but not our traditional understanding of the consumer in the price of the product , there must be high relative good performance, especially crafts and toy industry , less demanding on the luminescence time for body color and glow in the dark dye rate is higher demands
Problem absorbance response time for the application of crafts and toy industry is particularly important , but the length of time has not emitting very important, signs and other directions industries emitting time is important , so I hope that when customers choose luminous , where to buy glow powder choice the company's products for their luminous , luminous willing to give you a broader application of the product .

Brightness light-emitting phosphor coating

As the coating thickness increases, the coating also increases the emission brightness , but when the coating thickness reaches a certain value, the coating rate of increase brightness becomes smaller, because the light intensity is contained within the light emitting unit area determines the number of powder , as the coating thickness increases , glow pigment powders includes a number of phosphor increases. However, when the thickness reaches a certain value, the force of the coating covering the bottom of the glow powder suppliers on the light emission luminance contribution coating is reduced, so as to increase the coating thickness increases the brightness of the luminous paint is no longer apparent.

Luminescent material particle size on coating application

Luminescent material particle size on coating application and the luminous intensity has a great influence . If the luminous powder particle size is large, the paint easy precipitation , distributed unevenly affect workability , glow powder suppliers ; if the particle size is too small luminous powder , luminous nature may be destroyed, afterglow time is not long lasting. However, coating processing performance, the luminous powder particle size finer the better , preferably greater than 360 mesh . Luminous powder dosage on the coating properties also have a great impact , luminous powder with less, its total luminous intensity is weak , with the increasing amount of luminous powder , coating significantly increased brightness , but the luminous glowing stone pebbles a certain amount , the then light emission luminance of stable coating . In addition, the luminous powder expensive, its excessive use , will increase the cost of paint . Based on the above considerations, luminous powder dosage of 10% to 20 % is appropriate.

luminous pigment molecules

Rare earth doped alkaline earth aluminates attenuation mechanism exponential decay with temperature , the lower the temperature , the weaker intensity , temperature, light intensity increases rapidly , the decay time is much shorter.
When the coating is lighting conditions , the part of the light is reflected , another portion of the light into the coating interior. Into the glow gravels emitting pigments are partially absorbed by the pigment in the light-emitting molecules are excited , when these molecules will return to the ground state by radiation in the form luminescence . Therefore, the luminous paint luminous paint luminous performance depends . Rare earth doped glow pigment powders aluminate photoluminescent process can be divided into three main stages: light absorption , energy transfer , the emission of light . Absorption and emission of light occurs in the transition between energy levels , have been excited state . Excited state of motion is the energy transfer process .
