light-absorbing sunlight or under light irradiation

Luminous material non-toxic , non- radioactive , the production process also produces no harmful substances , is a new type of environmentally friendly materials, are rapidly replacing driveway gravels extensive use of luminous powder , luminous powder in the production and use of the process will produce H2S, SO2 pollution of the environment , materials in the presence of toxic heavy metal ions , the future will gradually reduce and even eliminate the use .

The main features luminous powder is available in sunlight or light irradiation light absorbing 5 to 20 minutes later, after the absorption of light energy into stored in the crystal lattice , Photoluminescent Masterbatch in the dark energy into light energy and light, can be effective continuous light (light emitting brightness greater than 10 mcd/m2) reached 8-10 hours , brightness decay to the lower limit of the human eye to observe (0.32mcd/m2) of time up to 70 hours, chemical stability, absorption , STORING , emission process can be repeated , stable product performance, service life up to 20 years .
