General highlighted pink around 20000-25000 . Since the initial rapid reduction sad moment ,garden decorative stones , capturing moments error greater impact on the general brightness with one minute to more appropriate time . Highlighting powder is generally 3500 (med/m2) above , the glitter around 2800 , Cape glitter around 2300.

Printing equipment and flower choice

When printing paste printing luminous applicable more widely available equipment manual cold platen , flat screen, screen printing machine park . Since the printing paste screen printing on fabric surface pile volume, brightness is good ; while the use of screen printing Photoluminescent Ceramic be appropriately Fangmanjusu and select the appropriate network pressure scraping scraper lip and , in short, to strive to achieve a higher plasma volume , can printed fabrics have a higher emission luminance . For general selection screen mesh cloth 60 to 80 mesh is appropriate, pattern flower design to the point and small area or in the 0.3 ~ 0.5cm wide grid lines as well. Patterns in a variety of small animals such as printed animal 's eyes luminous luminous photoluminescent pigments after nightfall eyes sparkling, increased fabric artistic charm. For plants pattern in the core of its small flowers or floral printed luminescent paste at night the effect is also very interesting.

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 .

Storage temperature change powder

Storage: reversible temperature change color pigment itself is an unstable system ( stable it is difficult to change ) , so its light, heat, anti-aging properties far less common pigment in use should be noted.
( 1 ) Photoluminescent Gravel , temperature change pigment lightfastness poor, under the strong sun exposure will soon fade fail, so it is only suitable for indoor use. Avoid strong sunlight and ultraviolet light irradiation , this will help prolong the life of color pigments .

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 .

fluorescent leak detection

Obviously, the human eye alone is difficult to accomplish such an arduous task. In this case , the operation is simple , reliable and economical fluorescent leak detection method for its efficient , speedy and accurate advantages widely accepted by the market . glow in the dark stone , fluorescent leak detection in the promotion process , but also often hear people complain about poor use of fluorescent leak sound effect class . After analysis found that most of the improper operation or due to improper use of the product pigment powder suppliers . Epica technology company with many years experience in the field leak we explore how to properly use the phosphors on the dust bag leak detection . Here's a brief introduction to fluorescent leak .

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 .

Preparation method

1 , the selection of good transparency neutral organic resins such as acrylic resins , epoxy resins, polyurethane resins, polyester resins , PVC resins, polyvinyl butyral resins , SBS resins ; 2 , the effect of dispersion of the light-emitting contradictions , garden decorative stones should use powder of 200 mesh or 300 mesh , and the other based on different paint types , for different purposes and requirements of the customer to choose the brightness of the powder particle size , with the total amount of powder coatings to 20% -50 % (wt).3 , luminous best equipment without metal grinding ( so will pollute the luminous black ) optional high-speed dispersion photoluminescent paint , or with a non-metallic liner milling equipment ;4 , the choice of 2000-5000 poise viscosity resin coating prevents light pink precipitate , or additives added to adjust the viscosity of the mediation ;5, can not use additives containing heavy metal compounds .

Luminous ink preparation method

1 , transparent ink ;
2 , resolve conflicts and dispersion of light effects , luminous powder particle size should be selected more than 300 mesh powder material, some printing inks require a higher particle size of glow in the dark material  should be selected according to the actual situation of particle size , powder substance content of 20-50 % ( by weight ) ;
3 , luminescent ink grinding metal equipment can not be used , if necessary, can be plastic or enamel -lined ball mill or sand mill equipment using high-speed dispersion best way ;
4 , may be appropriate to add a photoluminescent films of transparent paint , tinting , but the afterglow indicators have different degrees of decline ;
5 , depending on the choice of different types of substrates such as transparent ink : metal substrates should be used metallic inks ; substrates PVC PVC inks should be used.
