Application of environmental protection long Photoluminescent film in resin

  1. Resin and varnish

The selected resin should have better light transmittance, and at the same time, because the Photoluminescent FILM is weakly alkaline for a long time, so the resin is better for neutral or weakly alkaline.

Available resins and varnishes: epoxy resin (e440), polyurethane resin (or varnish), amino varnish, polyester resin, acrylic resin, hydroxyl acrylic resin, acrylic acid

Polyurethane varnish (two components), light colored alkyd varnish, fluorocarbon resin, etc.

  1. Selection of auxiliary agent for sceneway Photoluminescent film

Light-emitting coatings are mainly composed of dispersants and anti-settling agents. Heavy metal compounds cannot be used as additives.

Photoluminescent pigments

Alkaline soil aluminate system, silicate system, zinc sulfide system can be used, the amount of general 15~50%

Photoluminescent film production technology

The preparation of coating should use glass or enamel containers, Photoluminescent material particle size as small as possible, when the preparation of coating, not grinding, should use high-speed mixing method, the relative proportion of Photoluminescent material is 3.6~4.0, when the preparation of coating is very easy to sink, through the use of anti-settling agent, can improve the storage life of Photoluminescent coating.

Screen printing Photoluminescent signs, signs note

Photoluminescent signs need to use Photoluminescent ink, Photoluminescent ink used in the signage industry is generally the use of manufacturers according to their own signage products use purposes and requirements of their own to get better use effect and economic cost.

Usually is in the ordinary transparent ink with a certain proportion of Photoluminescent materials through simple mixing processing can be made into Photoluminescent ink use, if stored for a period of time to facilitate the ink of the full wetting Photoluminescent materials, the surface of the printed product smooth will be better. The specific selection of transparent ink and silk-screen substrate, simply choose the appropriate substrate for transparent ink.

Amount of environment-friendly long-effect long-afterglow: generally 30-50% of the total amount (luminescent material and transparent ink 1:1 ~ 1:2), according to the brightness requirements of printed matter to determine the amount of luminescent pigment. The higher the content of the ink, the higher the Photoluminescent brightness of the printed products with it, the longer the Photoluminescent time. The viscosity of the processed luminescent ink is about 300 ~ 500pa·s.

When, should control the printing speed, with thinner to adjust the ink viscosity, in order to adapt to the requirements of printing

When using luminescent ink for screen printing pattern and logo, generally choose polyester mesh below 200 mesh, in order to achieve better Photoluminescent effect can choose larger particles of high brightness PHOTOLUMINESCENT FILM Sign (such as gl-2 sl-2, etc.) with 80 ~ 100 mesh screen printing.

Photoluminescent ink is better printed on the white substrate, the use of the bottom reflective effect to improve the printing pattern or logo Photoluminescent brightness and afterglow time. If the substrate is not white or light color, need on the substrate with white or light color of the ink screen, the thickness of 0. 1 ~ 1. 0 mm. Printing Photoluminescent ink coating thickness control at 130 ~ 150 m, Photoluminescent effect is good, such as 80 mesh screen printing twice, you can achieve this thickness.

General in the field of sign requirements such as blinking effect is good, more use of 80 ~ 100 mesh, while the light effect is good, but the printing of the apparent effect is poorer, the surface is rough, sometimes need to use 160 to screen printing on the surface again a finer products (such as 8 c – a) get good effect of the surface smooth, brightness can be guaranteed, but the process is relatively complex, need to consider the cost effect and other factors.

The amazing “Photoluminescent Film path” is completed

The Photoluminescent Film path is more than 560 meters long and can emit light and graffiti

Nightlight walk is located at the west end of the bike path from shanhoucun, baoshan community, donghai street, green road of mountain line to about 2.5 km of forest park (located in shanhoucun, close to daping mountain community). Last night at 9 o ‘clock, the reporter came to the scene, and found that the side of the bike path is different, this Photoluminescent Film road issued soft light.

“Photoluminescent Film road” more than 560 meters in length, 3 meters wide road, head and tail of 65 meters light mapping on the road, the middle section of the fluorescent road semicircle pattern. During the day, the “noctilucent path” absorbs sunlight and emits a charming soft light at night.

In the interview, the reporter and the staff discovered unintentionally, “night light diffuse path” also can write: write down “quanzhou”, “mountain line green path”, “hello” and so on with the flashlight on this road surface, again after the flashlight turns off, these words actually shine, the font is clearly visible.

“It’s funny how the glow-in-the-dark rambling becomes a ‘confession’ wall.” A citizen walking up the mountain Mr. Li said with a smile, I heard that the mountain line greenway has a road that will give off light, I came up specially, I could not think of the road will not only give off light, but also write on it.

It glows for 8 hours at night with sufficient light during the day

Project department relevant personage xiao told reporters that in the original design, and no Photoluminescent Film’, then the city of mountain line green way of locating the ascension, and again please Shanghai landscape design institute according to the nature, the humanities environment surrounding the mountain line the greenway design, such as design institute put forward “Photoluminescent Film’, usually go there on special trip for the sea, the sky road” concept. It is reported that the domestic has been built in the municipal leisure road, quanzhou first use of this high-tech materials, “can also say that this section of quanzhou” Photoluminescent Film road “in the domestic is the first.

“It absorbs light during the day and it glows at night. If it absorbs enough light during the day, it glows for more than 8 hours at night. Then it gradually fades. Lu said there are three colors in the luminescent Film path, namely blue, yellow-green and dark gray.

Although design is a circle, but want to do very difficult, above all “drawing board” — the dry degree requirement of the ground is very high, want to make sure the ground does not have water above 7 days, and cannot have dirt, worker besides wipe water vapor with cloth, still must use drying equipment to blow sometimes dry, encounter rainy day, have to spend a lot of time to deal with the ground. In addition, because there are many rings, the color should be pure, so the construction should be slow, and the next step can only be carried out when the color is dry.
