Luminescent paint application methods

* Luminescent paint
Phosphorescent paint phosphorescent pigment is mixed into paint and varnish -like coating . Varnish must be highly transparent , and selection of the material to be coated and the coating method ( brushing , injection , spraying , coating machinery , etc.) is also necessary.
In addition , we must take into glow in the dark stones and other coating properties , if the choice can improve the stability of the luminescent light lacquer paint better.
Phosphorescent paint and varnishes standard mixing ratio of 1:1 by weight . Luminescent pigment content the higher the brightness is also higher.
Luminescent coatings for transparent varnish ( excitation light transmittance of light release ) the higher the brightness is higher .
Varnishes and thinners used in luminescent paint must not contain any heavy metals because of chemical reactions luminescent pigments and heavy metals will make it degenerate and luminous failure.
Phosphorescent paint coating of standard fluorescent pigments 0.1mm, brightness higher the thicker the coating , when saturated at about 0.3mm.
1 g phosphorescent pigment and 1 g of a mixture of varnish coating may be applied in the area of 0.1 ( thickness ) X10X300mm.
When part of the background painted white , brightness effect after coating the best .
For example, the coating thickness of 0.1mm phosphorescent paint on a white background of light attenuation rate is set to 0 , then the silver is 10 - 15% 30 --- 35% green , and black on the dimming rate of up to 45 --- 50%.

for luminous paint luminous powder production technology

Is a luminous paint luminous paint ( luminous ) , resins, solvents and additives by a certain percentage by special processing technology made ??. Each of the light emitting component determines the performance of the coating , simply described as follows :
A resin varnish : fluorescent paint should have a good transparency, and because the light emitting substance is alkaline pigment , the resin is preferably neutral or alkaline, if the aqueous resin aqueous coating , the light emitting pigment surface water treatment needs . <BR> Resin varnish can be selected varieties : Epoxy (E440), a polyurethane resin ( or varnish ) , amino varnish , polyester resins , acrylic resins , hydroxy acrylic resin, polyurethane varnish ( two-component ) , color shallow alkyd varnish , glow in the dark resin.
2 additives choice: luminous paint main dispersant additives , anti-settling agent composition, heavy metal compounds can not be used as additives.
3 luminous paint : You can use alkaline earth aluminate , silicate , zinc sulfide system , etc., the amount is generally 15 to 50 %.

At low temperatures lower luminous intensity

Captured by the trap level ( in the course of the external excitation light source , electron transitions from the ground state to the excited state (process 1 ) , a part of the electronic transitions back to a low energy level of Eu2 + to produce a light decorative aggregate ( Process 2 ) , through another portion of the electronic relaxation 3 ) . When electrons are stored in the trap energy absorption and re- excited by the excited state back , then transitions to the ground state and light is emitted . When the low temperature trap level is not conducive to the electron from the fluorescent paint  back to the excitation , the emission intensity is low at low temperatures , when the ambient temperature is increased in favor of traps electrons excited by the excitation back , so the higher the temperature emission intensity .
