Phosphorescent ceramic in swimming pool and washinng room

Phosphorescent Ceramic are made from powdered paint pigments and high quality ceramic tiles. After 10 to 30 minutes of absorbing visible light, phosphorescent ceramics will glow in the dark for more than 12 hours, and phosphorescent ceramic tiles are suitable for swimming pools and bathrooms.

About Realglow Luminescent Sheets

Realglow luminescent sheets is made from the powdered paint pigments and high quality PVC materials. Absorption of visible light 10 to 30 minutes, Realglow photochromic piece will glow in the dark over 12 hours of darkness in light yellow during the day, night yellow-green, glowing piece of non-toxic, no radioactive It is very suitable for use solvent ink for digital printing, screen printing.

luminescent sheets three main reasons

First, the current impact of the European debt crisis is still the continuation of debt recovery and development of the manufacturing sector will take time , domestic housing market is still sluggish , realglow photochromic pigments market will have a direct impact ; second affected domestic raw materials , rising energy prices , the slowdown in the steel industry , the material needed for the production of iron oxide reduction in scrap metal , will result in raw material prices . Coal , electricity and other energy prices and acid, alkali and other chemical products prices, will make the product costs continue to increase ; Third , continue to release new capacity in the return of U.S. manufacturing background , some domestic companies are implementing new , expanded production projects . The new incremental continue to gush , realglow powdered paint pigments difficult to fall in business inventories , short-term domestic and foreign markets is difficult to recover, market competition will continue to intensify.

luminescent sheets when heated process

Luminous plastic luminescent material when heated process , they often turn black , affecting play its luminescent properties .realglow luminous masterbatch by equipment selection and process conditions to control both . Choose one with improved processing equipment. By adjusting the screw configuration , so that the processing of reducing the shear and friction material , to reduce the degree of blackening of the material. (I) reduce the aspect ratio of the screw to screw the best selection of aspect ratio 20 / 1 , can reduce powdered paint pigments time in the barrel , reducing the likelihood of products blackened . (Ii) Reduction of the form of adjustment screw engaging a screw block module , remove the five pairs of engagement blocks , the block into the thread and re- combining element arranged to reduce friction on the luminescent material .

luminescent sheet simple features luminous

Absorb foreign advanced technology , specializing in manufacturing luminous , well-equipped , strong technology, excellent quality , excellent stability .
If some users in the choice of luminous , without knowing the luminous performance of some time , it will photoluminescent signs detours in the selection and use of luminous in the final analysis is to understand after some simple features luminous , and select the appropriate own processes and requirements luminous , do not blindly pursue AlliGHT long as all luminous light two hours after the already very weak, said light emitting 10 hours , 20 hours is just theory test results , practically meaningless.
With luminous in various handicraft industry and the toy industry applications, more and more customers powdered paint pigments luminous to change the performance of their products, but many of the characteristics of luminous powder itself is most customers do not know , for example, now there are many on the market luminous , not only a difference of quality, price is also very different .

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.

Light emission intensity can be increased coating

The need for surface modification or coating materials processing , change surface properties of the pigment , improve the water resistance and weather resistance , and to improve the photoluminescent pigment dispersion in the coating , compatibility . Photoluminescent Masterbatch or aluminosilicate particles surface-coated nano waterproof layer ( titanium dioxide , zinc oxide , nano-alumina , nano- silica ), the luminous intensity of the luminous paint can be increased by 20 % or more, afterglow time extend more than 40% , water scrubbing more than 5000 times . Common luminous paint exists for the current poor impact resistance , abrasion resistance good , powdered paint pigments slower and other issues , the author uses environmentally friendly energy saving light-cured coating technology system, just a few seconds can be completely cured , add special plasticizer, may effectively address the issue.
