Paint and ink coating thickness is preferably greater than 100μ, such as up to 130μ ~ 150μ, its best, (with a 80 mesh screen printing, twice to achieve this thickness). Luminous recommended dosage is 10% of the total weight to 70%, the more luminous the better usage. Depending on the printing material, choose different types of transparent substrates, such as printed metal, the metal should choose special inks, such as printed PVC material, PVC is necessary to choose a dedicated ink, the higher the better transparency. For use water-based paints and inks, decorative gravels‍ luminous microencapsulated subject to special treatment. 

Play a luminous paint performance Phosphorescent Ceramic

Precautions 

Play a luminous paint performance, must be complete and correct construction. The following are considerations on construction: 

(1) understand the performance of the luminous pigment‍ required luminous paint method of construction: the case of professional construction time: We recommend spraying a polymer coated agents on the ground floor to the second floor and the completion of the film, so can enhance adhesion, weather resistance and paint life. 

(2) to do a complete surface treatment: Surface treatment of the appropriate or not, has a great influence on the performance and life of the film, it is necessary to completely remove the rust, grease, and other foreign matter to be constructed and fully dried after brushing. 

(3) luminous paint should stir: pigment, resin mixture of liquid and luminous luminous paint department, from manufacture to use, there may be a period of time, and it is inevitable that the separation and precipitation pigment, or luminous of, so before use should stir. 

(4) once the brush thickness should not be too thick: driveway stone‍ once when the thickness of the brush if too thick, prone to diarrhea flow, wrinkles and other phenomena. So do proper control, multi-layered coating to do construction. 

(5) should be lower laminate coating paint dry before construction: do the laminated coating, the paint is not dry when the following layers, it is prone to wrinkling occurs even infiltrating the underlying paint peeling. It should be lower to the upper layer of paint applied after the paint dry. 

(6) at low temperatures and wet weather to avoid construction: When the temperature drops below 5 ℃, will reduce the paint to dry extreme, while in humidity over 85RH%, will produce nebula fog, dimmer, and even affect adhesion, and should therefore be avoid construction in such cases. 

(7) try to remove dust: dust will not only affect film properties, can also damage the appearance, so clear and clean as possible. 

(8) angle iron screws, plus Tu link at work should be done: at the angle iron links, welding or screws and other parts, easy to do because they do not complete the construction, plus painted the work should be done to make up for, Photoluminescent Tape‍ and pay attention to avoid holidays, brushing unequal circumstances occur. 

(9) the amount of attention Thinner driers shall be arbitrarily added: paint as too strong, when adding Thinner need to pay attention to the amount of its allocation, shall not affect the opacity and the film thickness, the general situation is not more than 5% in principle. Although they driers can promote drying of the paint, but excessive driers easily lead to quit phenomenon is dry inside, while leaving the film after drying to continue to promote the film of aging. 

(10) Fast Drying: heated drying 65 ℃ ± 5 ℃, drying time is about 6-10 minutes.‍

What is the principle of luminous road photo photo luminescent powder

Questions: 

What is the principle of luminous road? What's the difference with the traditional road reflective logo? It really can save energy and replace street lights? 

Answer: 

According to media reports, the nature of the road is the photoluminescent powder‍ use of light-emitting a glow in the dark fluorescent powder to make signs, the roads automatic light. 

Road use light-emitting phosphors are long afterglow luminescent powder." Recently, Professor of Shanghai Jiaotong University Daide Chang told reporters that this material can absorb sun light during the day, at night and gradually release the green light. 

The material is sent only light in a dark environment, the eyes can be felt during the day feel." Professor of Chemistry and Molecular Engineering, East China University of Technology Shen Yongjia further explained to reporters, also called afterglow luminescent powder luminescent materials, in natural light irradiation, or other artificial light sources that can store energy of the external optical radiation, and at a temperature (room temperature) and for a long period of time to slowly release the stored energy in the form of visible light luminescent materials. 

It is understood that since has good luminescent properties, since the 1990s, luminous paint‍ long afterglow luminescent powder began to receive widespread attention, and began to apply at night signs, emergency lighting and light-emitting ceramic. 

In China, the ground reflective logo has been an important means of auxiliary lights. By car lights, the driver can generally see the road. Then, add the mark compared to the way long afterglow luminescent powder, both of which have anything different? 

Daide Chang said that the main difference between the two is that one is self-luminous, a passive reflector. "Active glowing effect to be significantly better than conventional reflective effect, traffic safety has been significantly improved." 

In addition, the effect of long afterglow luminescent powder, the report Photoluminescent Pebble‍ pointed out that it can continue to light in the dark eight hours, in order to protect the lighting needs of the night, you can replace the lights.
