afterglow and infrared

Luminescence materials both at home and abroad mainly zinc sulfide, SRS cas, luminous ceramic light green and yellow. SrS, CaS the deliquescence of materials, difficulty in widespread application. So the main ZnS luminescent material administered on the market as the base photoluminescent pigment. Persistence, but it is only 1 to 3 hours, and the light (the sun), ultraviolet light and black perishable wet air, so that in many applications is restricted. Adding cobalt and copper activation of ZnS luminescent administered with long afterglow, the photoluminescent pigments quenching with infrared phenomenon, luminous aluminum light (including red) radiation, afterglow quickly extinguished. 

The use of luminous paint spraying

Flat paint covered large area demand does not recommend the use of spray (spray air pressure gun, the better). When using air spray can be used directly, without dilution or depends on the discretion to add thinner, need to spray viscosity (with BAC or toluene can be), glow in the dark dye glow in the dark pebble should join the amount of thinner ≦ 5% advisable, in order to avoid reducing its covering force. Luminous paint (oil painting since the dry), containing elastic coating paint water-based paint and doubt erosion generally polar solvent mixture system, please to be on a small scale before use prudent or hide in the first instance. Should be taken before spraying the surface cleaning, if not flat first maintenance will smooth suspension; And after waiting for it to dry completely, then pre spray acrylic series (ordinary) white photoluminescent pigment primer is better. In order to better optical storage luminescent paint advice is below before coating acrylic coating white primer (normal). To spray primer is dry, spray on luminescent paint spraying, please distance on the surface of the coating for 15 to 25 centimeters advisable, gush about 5-10 minutes or so, a thin layer, and then spraying the second channel. Each channel 5-10 minutes advisable, injection time should be sprayed at least three minimum benchmark, even after, such as spray; Spray can be coupled or above, the fourth channel (night better brightness) its optical storage stronger thickening of coating film thickness. Luminous paint dry time about 15 to 20 minutes (table), spray paint spraying again after the completion of visual demand, to make more beautiful and bright luminous pigment use time more durable paint surface. 

luminescent sheetis a kind of energy-saving products

Luminescent plate and light, electric, magnetic, and many other features of the particularity of the luminescent sheet structure. This material has a long afterglow time, high brightness, chemical stability, etc. New research and development of rare earth decorative gravel luminescence, not only promote the rare earth luminescent material resources of the comprehensive utilization ratio of resources advantages into economic advantages, but it doesn't need power supply can shine, so it is a kind of energy-saving products. Glow in the dark stone intermediaries, factors and trends.

photoluminescent pigment

Material glow in the dark can improve the luminous light lacquer paint better. The stability of the luminescent sheets tumbled rubble and 1 standard mix proportion of varnish: 1 weight. The brightness of the luminous pigment content is higher for transparent varnish who. The Luminescent coating (excitation light transmittance of light release) the higher brightness is used in Luminescent paint must not contain any heavy metals glow in the dark dye higher due to chemical reactions of luminous pigment. Varnishes and thinner, and heavy metals can make its deterioration and the standard thickness of 0.1 mm light failure. The Phosphorescent paint coating, the higher brightness, the thicker the coating pigment photoluminescence at about 0.3 mm. 1 gram of Phosphorescent pigment and a mixture of 1 g varnish coating can be applied in the background (thickness) X10X300mm. 0.1 the When the area of the part after coating painted white, the best effect of brightness.

Photo-luminescent material is defined

After the light-emitting material inside is in some way to absorb energy in the form of optical radiation outside the thermal radiation emitted from the excess energy in the process. Excitation light emitting material generated phenomenon, known as photochromic masterbatch. Photoluminescent material is a major application area lighting, including low-pressure mercury lamp, high pressure mercury lamp, fluorescent color, three-color lights and UV lights. Another important field of application of its plasma display.
