Luminescent pigment luminous brightness and visibility

We often have this experience at the cinema, from the bright outside suddenly into a dark room will not see anything, you can see when your eyes adjust to the darkness of the surrounding objects . Glow in the dark pebble may have optic nerve from the eye to bright light and darkness to light two different neural systems are explained . This is also called the eye of the dark adaptation.
Brightness luminescent pigment belongs to a weak light , even in the same light conditions , also due to the adaptability of the dark eyes and a considerable visual difference . Moreover, the visual is also affected by external light , the darker the surrounding The higher visibility brightness , visibility longer .
Typically, the sound can be seen to the naked eye brightness of 0.01mcd/m2, but brightness is not unconditional can glow in the dark sand and visibility of its time visibility on dark adaptation by the eye , outside light , shape, size , distance restrictions.
Phosphorescent pigment of the special light stability of the treatment , but also due to long-term use in outdoor combined action of humidity, temperature , ultraviolet light and dark .

Luminous use

The luminous paint luminous ( light pink ) , an organic resin , an organic solvent and additive composition , in order to avoid damage during the preparation luminous crystal structure , resulting in attenuation of the light-emitting performance , using a metal Glow in the dark pebble can not be other processing methods , taking into account the the luminous dispersion in the resin , i.e., preferably with the box.
  Usage:
     1 , can be carried out using luminous paint brush, roller , spray coating , curtain coating and other processes
     2, luminous coating reaches more than 150um thickness , in order to obtain a more desirable emission brightness ;
     3, in the luminous white primer decorative aggregate the bottom below , can improve the luminous brightness ;
     4 , the above white light-emitting -clear coating can improve the coating gloss and weather resistance ;
     5 , the coating can be adjusted according to construction methods.

color materials that tell you about the knowledge Dreaming

One , Dreaming principle : the use of UVA energy photosensitive molecules key to open , making it jump from the low energy stage stage . That is never visible jump visible . Thereby producing Glow in the dark pebble. When the loss of ultraviolet radiation or temperature rises above 45 ℃ , the light-sensitive molecules to close . Is restored to its original color
Second, the application form and color photographic materials: light-sensitive microcapsule powder as core , plus Malamine heyday as the shell material to form 1-10UM photosensitive pigment color , moisture content of 0.3% or less to heat 280 ℃. 1 , light pink base color with glow in the dark stone , blue, yellow , red. And good color stability . High mobility , easy to uniformly dispersed , can be mixed with each other , and can also other pigments, fluorescent pigments share. 2, due to the different base colors and materials with time .

Paint soft fluorescent pigment production Precautions

Fluorescent pigments are pigments based on thermoplastic resins , one of the most widely used fluorescent pigment series , need not be applied to a wide variety of uses solvent resistant ; Glow in the dark pebble  be used for a long time is not stored in an aqueous system . Such as: paper coatings , textile printing paste , A-type gravure inks, paints, screen printing ink , PVC plastic and PVC organic sol , but it also can be injected molded vinyl , polyolefin , and all kinds of plastic below the operating temperature of 193 ℃ . Model and color: pink . Red . Red . Orange . Orange . Lemon . Green . Blue . Purple .glow in the dark stones
Physical and chemical properties : the proportion of the average diameter of the softening point of the thermal stability of the material absorbing the amount recommended dosage.

phosphorescent light-emitting material

Luminous , long-lasting luminous luminescent material emitting a light-emitting material Si network has chemical stability, high brightness, non-toxic and non-radioactive and other advantages. Glow in the dark pebble strong light absorption ability by absorbing ultraviolet light or visible light , so the conversion of light energy stored in the lattice , in the dark turn energy into light energy and light. With the characteristics of its products are products with a luminescent powder made glow pigment powders  a variety of visible light absorption in the light after a few minutes , you can continue to light in the dark night more than three hours, the luminance and duration is 10 times that of traditional luminous material above ; think a light-emitting material is waterproof luminous obviously good water resistance , more versatile .

Use luminous with ceramics and precautions

1 , general use 150 luminous body is the best. 2 , and can be used as phosphors used as an ordinary toner , the actual time of the production process , to select suitable additives for the oily ink sufficient stirring ( refrain metal melting device , in order to avoid decorative aggregate time will be black ) , fully dissolved combined with a 80 mesh screen after printing ( pre- sifted better ) , to luminous intensity and a long time, you can print more than a few times , usually two to three times for the best. 3, if required , and dissolve blocks or transparent glaze mix , luminescent powder dissolved in blocks or transparent glaze ratio is generally 1:1 or 6:4 or 6:10 , so that the body can be debugged according to the occasion want to achieve results. 4 , burning out the finished ceramic frequently encountered problem is : glow in the dark pebbles of bubbles, this problem is usually combined with each other additives or transparent glaze frit and chemical stability problems , change the scale or replace with additives. Defoamer can also be eliminated. 5 , luminescent materials and ceramic pigment mixed into use .

aluminate luminescent material is water-resistant

Rare earth aluminate long afterglow luminescent paint storage as an efficient , energy-saving "green" materials are widely used. Glow in the dark pebble characteristic is mainly given by the light-emitting materials , the development of a rare earth aluminate luminescent material poor water resistance , light color monotone , the study of the luminescence mechanism still remain in the speculative level, its organic - inorganic glow powder suppliers modification is still in the exploratory stage . But is moving to improve the luminous intensity , prolonged afterglow time , environment-friendly , light color diversity direction.
