Guang Hua Technology Co., Ltd.

Brief introduction on photoluminescet metal coating technology In the world, we are the unique manufacturer who can coat photoluminescent(pl) powder on metal surfaces, such as aluminum, steel, stainless steel, copper... With 10 minutes'' being irradiated in the sunlight, it can remain luminous at least 12 hours! Class d passed, the highest class in pspa I would like to show you our test method and result. If possible, would you please run the test by your local authorized institution? Light source:3 pcs toshiba fl20t9d119 wattbrghte daylight(insteadof sunlight) Distance from the light source to the pl metal plate:2.3 meter Time of exposure:20 min(ifexposed in sunlight,10 min is enough. ) The letter size on pl metal plate:2 x 1 ** in dark room without any light,20 hours latter. Human eyes can identify the direction of arrowhead and all the letters can be read without any mistake. Please note that human pupils need 1~2 minutes to fit the sudden darkness. In the darkness, at first, eyes can see nothing. When we enter a cinema, we can not see anything at the beginning. It is the same reason. In the sudden darkness and urgent situation human pupils will automatic enlarge to obtain light. ** in dark room without any light,48 hours latter... On a white wall, there are a pl alu. Plate and a white a4 paper. A white halo can be found around the pl alu. Plate, while the white paper can not be found on the wall. Also we can combine photoluminescent function and reflective function on one metal plate(prsign, photoluminescent&reflective sign). When there is strong light at night(suchas car light), the plate can reflect the light. It is normal function of car/road/street signs. In the dark room or at night, the pl plate can emit light without power(after-glowingluminescent sign). On the other hand, our product can also be applied in architectural decoration. Since it is luminescent feature, it can not be explored by any infrared ray detection instrument. This makes our photoluminescent product lines can be widely applied in military use, such as in air force(spaceship)navy and army. Furthermore, because its basic material is aluminum plate, which is anticorrosive and can be used at any outdoor places, even in jungles, mountain. Plastic photoluminescent products can never have this characteristic, since it is well known that, even in the indoor places, plastic can not endure strong sunshine. It will peel, and the plastic foil will crinkle, too. Our product lines make it come to true that photoluminescent products can be applied indoor and outdoor with perfect and unique characteristic. Even though we use rare earth element and aluminum plate, with unique and the most advanced patent technology in the world, our price is close to the plastic one. Meanwhile, it is well known that the rare earth element reserves in China are abundant, and China restricts the export of rare earth element. This makes our cost be lower than overseas manufacturers, which makes it possible for us to act as OEM manufacturer in China, if feasibility. Hope the above information can be useful for you to know more about our product lines. With any question, please feel free to tell us.
