A Special Synthetic Polymer-Photoluminescent Tumbled Gravel

Realglow glow gravels is a synthetic polymer, based on Realglow photoluminescent paint and synthetic resin. When exposed to light, the gravel of luminous pigment chemical became excited, will get (a e. luminous), the original is very strong, then slowly lower overnight. Glow in the dark place, where the environment light source, such as street lamps and miss the most clearly see the moonlight.

Due to the long afterglow luminescent Photoluminescent Gravel

Due to the long afterglow luminescent material removal can be light illumination in the dark a long time, so people will this material colloquially known as "luminous." Traditional luminous two categories: sulfur Compound-and radiation-excited type. photoluminescent paint‍ Sulfide including ZnS, CaS, etc., and chemical properties of these materials are relatively less stable in water and ultraviolet light easily hydrolyzed or photolysis, Afterglow time is generally two to three hours, life is also shorter. Excitation radiation type is incorporated into radiant energy emitted by radioactive substances within the material as an excitation source, excitation and emission center Glow. Because such materials containing radioactive substances harmful to the environment and human health, Photoluminescent Ceramic‍ has been banned in most countries use. 

photoluminescent paint and screen printing inks

Neutral or alkaline transparent resin should be used.
Photoluminescent pigment avoid using metal containers and processing equipment.
Coatings should be noted that the finished product and the moisture content of the ink , the higher the moisture content , the shorter the storage time .
Use high- viscosity resin , and add anti-settling agent to prevent precipitation occurs .
Stir before using uniform finished product that can be used to adjust the viscosity of the diluent , but can not use heavy metal compounds as additives.
Printing is recommended to use a white or reflective background color , can increase the brightness of the printed pattern .
Screen printing is photoluminescent pigment mesh 80 to 120 mesh .
Paint or ink when the coating thickness 120μm best.
Luminous recommended dosage is 20 % to 40%
Printed material is different , you should choose a suitable base paint or ink .

Different colors are used to distinguish the luminous device features

The signs are clear, unified ensure electrical safety is an important initiative , but because of the many wires , the color is not uniform , Photoluminescent Gravel , is apt to cause electrical accidents, therefore, to standardize operations , to protect the personal safety of staff . Signs are divided into color logo and graphic signs . Color flag used to distinguish the different nature of different uses wires , or to indicate somewhere safe. Graphic signs are generally used to warn people not to  photoluminescent paint  to dangerous places. To ensure the safe use of electricity , must be in strict accordance with the relevant standards using color logo and graphic signs. Standard color used in our national security , essentially draft international (ISD) the same standard .

Long luminous emission time

Long-lasting luminous rare earth materials by a non-toxic environmentally friendly , save by absorbing visible light for 10-20 minutes , or more light emitted up to 12 hours in the dark , Photoluminescent Sand up to 15 years . Good weather resistance, can be used indoor and outdoor , resistant to temperature 400 ℃ -1000 ℃, widely used : watches, toys , photoluminescent paint, fire logo , injection products, silicone rubber, printing or spraying.
◆ Ink Application: Screen \ offset \ transfer \ printing \ spraying , ( paper \ fabric \ metal \ glass \ ceramics \ plastic ) .
◆ Powder Application: Injection PP \ PE \ PVC \ PC \ ABS \ AS \ PU \ EVA \ PMMA and silica gel .

kinds of luminous color

The new light-emitting materials can be used as a luminescent pigment evenly distributed in a variety of transparent media such as paints , inks, plastics , rubber, paper, film , glass, ceramics, printing paste , used in clothing, footwear, stationery , watches, Photoluminescent Sand , signs, fishing gear and other consumer goods , but also can be used for architectural decoration, transport military measures , fire signs mark the import and export system , escape , rescue route signs , with the role of a good indication of the Fire .
Luminous range of applications :Long-lasting luminous powder luminous powder luminous powder luminous green color Type: luminous yellow-green , blue-green luminous , sky blue light luminous , luminous purple colored luminous , fluorescent luminous ,photoluminescent paint chart long-term thinking luminous high brightness, long lighting time , environmental adaptability, by absorbing various visible light automatic light, and can be recycled an unlimited number of permanent use , a very wide range of applications . The product is detected by the China Institute of Metrology , non-toxic , harmless , non-radioactive , lead, phosphorus and other harmful metals or chemicals , light new product is a new generation of environmental protection , safety, energy-saving luminous, bright light-emitting Si diagram pink highest emission time up to 12 hours.
