Advantages of glowing sheets

Glowing sheets has very low friction properties which are some of the best within the engineering plastics range and the Sheet helps produce low friction components. Photoluminescent Ceramic also has excellent abrasion resistance which helps provide components that are suitable for high abrasion applications. The sheet will absorb very low amounts of moisture which help creates components that are stable over a long period of time.

Phosphorescent Ceramic For Use

Photoluminescent Ceramic Tile can produce any shape or size to achieve the specified maximum and information/instruction display can all design will be needed for each application, such as "runners" way safety photoluminescent signs, export orientation and distance, disaster warning and similar stairs. The photoluminescence of color only two alternatives, at present, for the green and yellow and blue-green.

Function of Photoluminescent Ceramic

Photoluminescent Ceramic Tiles can be used floors, walls and ceilings where the use of paint, low location strips or other is not feasible. The photoluminescent sheet can also be used in already existing tile arrangements where the tiles will show the way out if power black-outs occur or smoke starts to fill the room/area.

Photoluminescent Ceramic Tiles and Photoluminescent Sign

The new Photoluminescent Ceramic Tiles can be produced to any shape or size up to a specified maximum, and information/instruction displays can incorporate any designs required for individual applications, such as photoluminescent signs 'running man' way out/safety exit, exit direction and distance, staircase hazard warning and similar. The Photoluminescent colors are limited to two alternatives at present, being yellow-green and blue-green.

Photoluminescent Ceramic Tiles application areas

Photoluminescent Ceramic Tiles can be used floors, walls and ceilings where the use of paint, low location strips or other is not feasible. The tiles can also be used in already existing tile arrangements where the tiles will show the way out if power black-outs occur or smoke starts to fill the room/area.

Here are some application areas:

1. Ceramic tiles are already in use or are planned so that the esthetic value is maintained.

2. The surface is subject to wear and tear that ordinary signages are not suitable.

3. The surface need flashing or is even under water.

4. They as a photoluminescent sign decorate to toilet and washroom, natatorium and aquarium, etc.

people use luminous glow characteristic Phosphorescent Ceramic

Luminous Applications 

Application in life 

In real life, people use luminous glow characteristic long, made of weak light source, in particular the usefulness of the military sector, to put this material is coated on aviation instruments, watches and clocks, windows, machine various switches signs, door handles, etc., can also be used together with a variety of translucent plastic pressed into a variety of symbols, parts, supplies (such as power switches, sockets, fishing hooks, etc.). Photoluminescent Ceramic‍ These light-emitting components after irradiation, or unexpected power outages at night, after getting up and so it continues lightning light, so that people around discernible direction, bring convenience to work and life. The ultrafine particles mixed with luminous material in textiles, the color more vivid, luminous textile children wear can reduce traffic accidents. 

Application in industry 

With luminous in various handicraft industry and the toy industry applications, more and more customers began to change using the luminous performance of their products, but many features luminous itself is most customers do not know, for example, now There are many on the market luminous, not only a difference of quality, price is also very different, a lot of customers to buy their favorite luminous difficult. Mainly because there is no industry standard yet luminous, but not our traditional understanding of the consumer in the price of the product, there must be high relative good performance, especially crafts and toy industry, less demanding on the luminescence time for body color and the absorption rate is higher demands, if some users choose luminous, luminous without understanding some of a performance, it will take some detours in the selection and use of luminous in the final analysis, we must first understand After some simple features luminous powder, luminous choose their own processes and requirements best, do not blindly pursue AlliGHT long, all luminous in two hours after the light is very weak, said light emitting 10 hours, 20 hours is just test results theory, in practice the effect is not obvious. 

Previous articles have said the problem absorbance response time, phosphorescent pigment‍ which is the point of application of crafts and toy industry is important, but the length of time has not emitting very important, signs and other directions industries emitting time is important, so I hope customers Select the luminous time, to choose their own rational company's products luminous, luminous willing to give you a broader application of the product.

Luminous usage is according photoluminescent river rock

Luminous how to use 

Luminous usage is according to their actual situation, different requirements, luminance and different uses has a different use, can be summed up their own solutions to fit in the actual production process according to the product. Photoluminescent Tape‍ The following content is for reference 

??Luminous powder for injection: the ratio of luminous and plastic materials, generally is around 4% -10%, depending on the color depth of the product, plus less light color, dark color principle to pay more may be. A Ingredients: first spread of oil added to the raw stir for one minute, then add the luminous stir one minute, two minutes plus toner stirring, mixing time should not be too long, pay attention! Luminous very sensitive to long-term iron friction material will darken too long. Second, the injection molding machine: Injection confidential clean, temperature should be transferred to a minimum, can be injection molded, the material in the injection molding machine time not too long, to avoid burning, injection molding machines of different products, there are also differences between the new and old machines machine, machine-made and imported machines, which require debugging slowly resolved. Third, the luminous: In injection molding, the long-term luminous various reasons, injection molding, injection molding machine, melting temperature of the material may cause darkening short luminous efficiency (luminous ZnS) good performance in terms of black Photoluminescent Ceramic‍ injection point. If there are no special requirements for selection of short-acting luminous. 

???Luminous powder for printing: To reduce the paint, luminous powder luminous precipitation problems, you can use the high-viscosity resin, and add anti-settling agent, to be stirred before use, can be used to adjust the viscosity diluents, do not use heavy metal compounds do additives. Use white or reflective print background color based, can improve brightness and lighting time printed pattern. 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. 

Fluorescent paint application luminescent sheets

Fluorescent paint application 

Fluorescent paint luminous principle: 

Daylight fluorescent paint usually colored fluorescent pigment, and an acrylic resin prepared from a fluorescent material and a solvent is made. It can absorb in driveway stone‍ the light irradiation, sun light and forwarded another similar color of light itself, so the color looks very bright light, brightness up to about three times the general paint. Fluorescent paint is not our own light shine, we must have a light source. When the light source is terminated, the fluorescence phenomenon will disappear. 

Fluorescent paint Product Features: 

Fluorescent paint film is smooth, natural drying, bright colors. When subjected to some form of stimulation light, converting the absorbed energy into thermal radiation than visible light. Has good adhesion and good mechanical and physical properties. Fluorescent paint is mainly used water diluted aqueous coating, when used with water as a diluent, can brush, can be sprayed, must be applied only on the underlying white fluorescent effect. The higher the underlying whiteness, the better the fluorescent effect. 

Fluorescent paint Scope: 

Fluorescent paint mainly used in wall construction field, and is suitable for surface coating of metal, wood, ABS plastic and other substrates. Commonly used in Photoluminescent Tape‍ advertising, decoration, instrument manufacturing, transportation and other industries painting. 

Fluorescent paint Construction Description: 

1, before the fluorescent spray paint, hit a layer of white at the end, the best results; 

2, two different colors of fluorescent paint, do not be confused, so as not to reduce the fluorescent effect; 

3, in order to ensure quality, please use matching fluorescent paint special curing agents, diluents; 

4, for outdoor use fluorescent paint: hardener = 2: 1, indoor spraying directly, without curing agent. 

Storage and precautions: 

Fluorescent paint should be stored in a cool dry place and away from sources of ignition. General shelf life is 12 months, be sure to pay attention to see when using the production date. 

Also contraindicated in use with variegated mixed, so reducing the fluorescent effect. Excellent product quality with qualified construction quality in order to achieve Photoluminescent Ceramic‍ excellent light fastness properties and other application effect.
