Luminous powder for printing

To reduce the paint , luminous powder luminous powder precipitation problems , you can use the high-viscosity resin , and add anti-settling agent , to be stirred before use , can be used to glow in the dark pebbles viscosity diluents , do not use heavy metal compounds do additives.
Use white or reflective print background color based, can improve brightness and lighting time printed pattern.
Paint and ink coating thickness is preferably greater than 100μ, such as up to 130μ ~ 150μ, its best, ( with a 80 mesh screen printing, twice to achieve this thickness ) .
Luminous recommended dosage is 10% of the total weight to 70% , the more luminous the better usage . Phosphorescent Ceramics the printing material, choose different types of transparent substrates , such as printed metal, the metal should choose special inks , such as printing pvc material, we must choose pvc special inks , transparency, the higher the better.
For use water-based paints and inks, luminous microencapsulated subject to special treatment .

Considerations when using luminous printing paste

( 1 ) selection of 80 to 100 mesh screen cloth plate printing better.
( 2 ) storing luminous should now use the existing printing paste , paste in the distribution process should be taken to avoid mixing strong electrolyte and heavy metal ions in order to ensure the quality of the slurry .
( 3 ) deployment of good luminescent light emitting printing paste should endeavor to run out within eight hours , not long put .
( 4 ) If the dye or paint and other powdered paint pigments, printing paste flowers should be noted that the color bit version or spendthrift Priorities , general dye or paint color bit first , storing luminous after printing paste , printing paste can not be storing luminous superimposed on other printing paste , or affect the glow.
( 5 ) colored fabric has a great influence on the light. As to the brightness of white, luminescent color printing is 100 , the brightness of a light colored printing only about 80 to 90 range, deep in color printing will be in 80 or less of the brightness . The main reason is the light reflecting white or light colored fabric was stronger than the dark colored fabrics , dark colored part of the luminescent material absorbs light , so the light emission luminance decrease . When non- white printed material substrates should be printed in the issuance of a layer of white printing paste should be glow in the dark material by a light layer of the substrate to do , so you can guarantee glow.
( 6 ) printed on the fabric , by adjusting the viscosity of the printing paste storing luminous reasonable printing method and a light emitting layer to control the minimum film thickness of not less than 100 microns to about 130 microns is appropriate , therefore, the thickness can also be used thick colored plastic version version version to ensure the film thickness, can achieve the best lighting effects .

Phosphorescent luminescent pigment characteristics

Afterglow luminescent pigments can maintain visible 1-2 hours. But that depends on the type of excitation light source type and brightness , as well as luminescent pigments , outside light , dark adaptation of the eye , the coating area and visual distance and other factors.
* Excitation light in the ultraviolet content , Photoluminescent Masterbatch the excitation efficiency .
For example: a light source with the same illumination inspired brightness set to 100 units , then tungsten , white fluorescent light , compared with 180 units , and the black lights for 220 units.
* Luminescent pigment excitation time is basically not limited to stimulate the type and brightness of the light irradiation for about 2 --- 3 minutes to reach its saturation excited .
* Luminous pigment because of its brightness powdered paint pigments varies.
Initial luminescent brightness and afterglow luminescent pigment time is about 1.2-1.3 times the GB-U 's .
* Brightness phosphorescent pigment and its particle size increases with increased hiding power and dispersibility but its decline. Optimal particle size and dispersion of light emission efficiency and workability of 19 --- 25um.

Temperature change powder material uses

Coating: surface coating for all types of products, including PMMA paint , ABS paint , PVC paint , etc. ;
Ink: various types of printed materials , including fabric, paper , synthetic film, glass , etc. ;
Plastic products : Photoluminescent Masterbatch all types of plastic PP, PVC, ABS, silicone rubber and other materials of injection, extrusion molding .
Temperature change powder has a variety of low to high temperature range , depending on the temperature of different color can be divided into low temperature (10 ℃, 20 ℃), feel discoloration ( about 30 ℃) cheap gravel change color (40 ℃, 50 ℃, 60 ℃, 70 ℃, 80 ℃) and other materials ; temperature change pink colored to colorless , colorless to colored series.

Luminous powder preparation methods

  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 and the like ;
     2 , contradiction dispersion and Photoluminescent Ceramic, the luminous particle 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 , coating of total controlling the amount of powder in 20% -50% (wt).
     3 , luminous best equipment without metal grinding ( so will pollute the luminous black ) optional high-speed dispersion method , or with a non-metallic liner milling equipment ;
     4 , the choice of 2000-5000 poise photochromic sheets 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 .

Velcro will be posted on the clothes cold tablets

1 Velcro -type cold tablets with Velcro to stick on clothes , can easily washable , washable advantage of convenient, Phosphorescent Ceramics, you can only buy clothes , buy a few of their favorite patterns, free replacement patterns, the disadvantage is that there is no overall effect sewn nice , cold tablets prominent part in outside clothes.
2 is a fully integrated sewn cold tablets and clothes , cold tablets can not be removed . Advantage overall effect is photoluminescent exit signs, like an ornament in the chest, hand wash only drawback is that when washable , cold tablets part can not be immersed in water .
