The duration of Photoluminescent Pigment

The brightness problem that concerns noctilucent pink often produces doubt in new client, manufacturer says clearly can bright 10 hours how half hour is invisible, associate Photoluminescent Pigment manufacturer to deceive people immediately, cause a few unnecessary misunderstanding.

The unit of brightness of luminescent materials is usually CD /m2(candela per square meter), while the brightness of Photoluminescent Pigment is generally MCD /m2(millicandela per square meter). If we look at the brightness of common light sources, we will understand.

It reaches 10,000 ~ 100,000 CD /m2 under the midday sun.

Generally, there are only 1000 ~ 5000cd/m2 indoor during the day.

However, our light at night usually ranges from 100 to 1000cd/m2.

The brightness requirement of the emergency lamp is greater than 50cd/m2.

New electroluminescent signage with brightness of only 20 ~ 100cd/m2,

The maximum brightness of our Photoluminescent signage made of Photoluminescent Pigment will not exceed 10cd/m2, and the maximum brightness will be 1 ~ 2cd/m2 after 2 minutes, and 0 after 1 hour. 060-0. 0990cd/m2, 0 after 10 hours. 006-0. 010 CD/m2.

Therefore, the brightness of noctilucent Pigment observed in the daytime is more than 1cd/m2 due to the presence of ambient light (even in a dark room, it will exceed 1cd/m2). However, our eyes feel very dark due to the strong contrast between the outdoor and indoor environment. When observed in this environment, noctilucent Pigment often fails to emit light within an hour or so. If you use a drawer or paper tube to avoid light observation, then more than 10 minutes can not see Photoluminescent Pigment glow.

So why does our noctilucent Pigment manufacturer say it can shine for 10 hours? The reason is that the light that human eyes can observe under the condition of total darkness is very weak 0. 00032cd/m2, and usually Photoluminescent Pigment brightness attenuation below this brightness can reach more than 10000 minutes, that is to say, can continue to shine for 10000 minutes (166. In theory, the human eye can still see.

In order to illustrate the brightness of Photoluminescent Pigment image, in the early promotion of long afterglow Photoluminescent Pigment, said to be able to shine for 8 hours 10 hours and so on, and usually can only continue to shine for less than an hour of zinc sulfide Photoluminescent Pigment distinguish. In order to accurately express and testing instruments, to popularize and apply now gradually replaced by the data for 1 hour, due to large unit of CD/m2, so Photoluminescent Pigment Powder usually adopts the MCD/m2 (candela per square meter), usually an hour brightness are between 10 ~ 100 MCD/m2, different level of granularity and the product brightness is different, because the brightness is higher, the greater the noctilucent Pigment particle size and large granularity using performance is bad, so under the condition of the same brightness, the smaller the particle size of product, the more high-grade, of course the price is more expensive, in order to save the cost of materials, Generally will be allowed in the process conditions to choose a thicker product to achieve a higher product brightness.

The story of Photoluminescent Film cup

The Photoluminescent Film cup has a long history of more than 2,000 years. “China time-honored brand” jiuquan Photoluminescent Film cup is made of jade from qilian mountains, which is fine in texture, natural in texture and bright in color.

The picture shows the traditional Photoluminescent Film cup.

The legend of Photoluminescent Film cup is famous at home and abroad. In jiuquan, gansu province, under the qilian mountains, there is a “Chinese time-honored brand” Photoluminescent Film cup factory.

In the workshop, 57-year-old artist wei jianmin is polishing Photoluminescent Film cups. He has been working here for 40 years and has thick calluses on his hands. These rough hands are very handy when it comes to polishing a cup that is only 1mm thick.

‘conditions are better now,’ Mr. Wei said. But “some of the processes are still thousands of years old, so it still takes a week to make a glow-in-the-dark cup.” He picked up a “rag” made of a horse’s tail to clean a jade plate and told the paper, “only a cloth made of horse’s tail can be used to clean the waxed jade.”

“Making Photoluminescent Film cups is different from other jobs. You have to be slow and careful in the end.” Wei jianmin says, because the cup wall of finished product is less than 1 millimeter, do not pay attention to namely all previous work is abandoned slightly. Although the high-frequency motor is now used to save energy, but the cup wall produced is thinner, so it can not be distracted, “this is from the ancestors of generations of rules”. A cup from raw materials to finished products need at least more than 30 processes.

Wei says his biggest concern now is losing his craft. Today’s young people are reluctant to learn jade because it is so hard and dirty. Now he and master lu xuelian are the only old people in the factory. Master lu will retire after only one month, and he himself will soon retire. The entertainer said that if there were young people willing to pass on the ancient craft, he was willing to focus on passing it on.

Wei master and Photoluminescent Vinyl Film cup deal with all one’s life, he told the reporter, since ancient times, jade is a symbol of morality, people who deal with jade also have conduct. Do this line of bitter, treatment is not good, with his clever hands do other line of work income will be much higher, but because he grew up like Photoluminescent Film cup, a stem is a lifetime. Every summer, during the peak tourist season, many foreign tourists visit the factory and take photos with him excitedly. He said, the legendary Photoluminescent Film cup famous at home and abroad, bitter life is worth it, after retirement will continue to do Photoluminescent Film cup.

Application of Photoluminescent Film in oil spill operation

In order to promote the coordinated development of national defense construction by Photoluminescent Film, local economy, military struggle preparation and environmental protection, at the end of last year, six experts including professor zhang ke from ocean university of China reviewed and approved by the navy logistics department decided to set up the Photoluminescent Film project in a military port in sanya.

Oil boom is installed on the naval vessels stationed in the military port, including 4,880 meters of solid float-type rubber oil boom, and 7 sets of stripping equipment and oil spill recovery devices.

The solid float-type rubber oil enclosure adopts two layers of high-strength fiber cloth as the framework, and is covered with high-quality, easy-to-identify Photoluminescent Film Signs or color synthetic rubber. It is resistant to oil, abrasion, seawater corrosion and ultraviolet aging, with long service life and flame retardant characteristics.

Solid float, large buoyancy reserve, uniform force on the column, high overall strength, good vertical stability, strong oil retention. Smooth and clean surface, good for oil transfer and easy to clean. Connection rapid, reliable and drop quickly, easy to operate, apply to the surface of fixed long-term cloth, are widely used in the open ocean, the gulf, port, wharf, river waters, oil platform and other long cloth, Photoluminescent Film Signs can also be used in oil spill emergency operations, is used for sea or other water to control oil spill diffusion and transfer of the necessary important equipment.

Trends USED Photoluminescent film in cabin interiors

Nowadays, almost no part of an airplane cabin is free of aesthetic design elements and the most economical manufacturing process.

Take the sign system of cabin emergency passage as an example: the traditional cabin floor is always a wide yellow sign that is not compatible with the cabin design, or the use of electronic lights, which is not only not beautiful, but also requires high maintenance costs and a lot of energy. Photoluminescent Film are now commonly used in cabin exit sign systems because they can be seamlessly incorporated into wide-color carpets and require little or no care, allowing airlines to beautify their cabins while keeping costs down.

Britain’s STG aerospace offers more than 300 colours for its Photoluminescent emergency access marking system, and Lufthansa technologies offers a multi-colour “guidance system” that can last as long as an aircraft. In addition, the economy of these two
Photoluminescent emergency exit sign is an important reason for the popularity of these products, as they can work day in and day out by shining the logo directly under a common light source for only 10-30 minutes before the flight takes off.

“The trend used Photoluminescent film inside the cabin is now towards an aesthetic, which is to make the whole flight easier.” “Said Peter Stokes, chief executive of STG aerospace.

Organic Photoluminescent film

There are many kinds of organic small molecule Photoluminescent films, most of which contain conjugated heterocyclic ring and various chromophore groups, and the structure is easy to adjust. By introducing unsaturated groups such as ene bond and benzene ring and various chromophore groups to change their conjugate length, the photoelectric properties of the compound will change. Examples include oxadiazole and its derivatives, triazole and its derivatives, rhodamine and its derivatives, coumarin derivatives, 1, 8-naphthalimide derivatives, pyrazoline derivatives, trianiline derivatives, porphyrins, carbazole, pyrazine, thiazole derivatives, and perylene derivatives. They are widely used in optical electronic devices, DNA diagnosis, photochemical sensors, dyes, Photoluminescent brighteners, Photoluminescent coatings, laser dyes [7], organic electroluminescent devices (ELD) and other aspects. However, small photoluminescent sticker film are prone to fluorescence quenching under the condition of solid state, and devices made by general doping methods are easy to aggregate and crystallize, so the life of devices decreases. So many researchers on the one hand to small molecule research, on the other hand to find better performance of luminous films, polymer luminous films came into being.

Organic polymer optical film is usually divided into three categories: (1) the side chain type: small molecule luminescence group articulated on polymer side chain, (2) the main chain of the conjugate type: all the molecules are a large conjugated polymer system, (3) the main chain of the conjugate type: luminescent centers on the main chain, but separated from each other between the luminescence center did not form a conjugated system. The polymer luminescent films studied are mainly conjugated polymers, such as polybenzene, polythiophene, polyfluorene, polytriphenylamine and their derivatives. There are also polytriphenylamine, polycarbazole, polypyrrole, polyporphyrin [8] and its derivatives, copolymers, etc., which have been studied more.

In addition, the luminescent group can be introduced into the end of the polymer or the middle of the polymer chain. Kenneth p. Ghiggino et al. introduced the fluorophore into RAFT reagent and connected the fluorophore to the polymer through RAFT polymerization. As can be seen from the above luminescent polymers, most of them are conjugated polymerization of the main chain. The main chain polymerization is easy to form a large conjugated area, but its solubility and fusibility are reduced, making it difficult to process. However, when the luminescent group is introduced into the end of the polymer or the middle of the polymer chain, only the end group glows, and the molecular weight is not very large. If the molecular weight is very large, the content of the luminescent group in the polymer is low, and the fluorescence is very weak. The side chain polymer luminescent film is a strong complement to the main chain conjugated polymer.

  1. This film is often referred to as a photoluminescent object. Self-luminous objects may glow in the dark, but do not need to be exposed to sunlight beforehand. These films, often used as luminous markers on the dial and for making objects that glow for long periods of time, contain radioactive elements.
  2. Phosphorescent films are also often referred to as photoluminescent films because of their phosphorous content.

Application of photoluminescent film digital printing: photoluminescent powder is an ideal film for making luminescent ink, luminescent paint, luminescent plastics and luminescent printing paste. Ink not only suitable for screen printing all kinds of luminous effect the patterns of the text, such as signs, toys, calligraphy and painting, glass painting, stickers, etc., but also because of its high transparency, good film-forming, thin coating, etc, can be in all kinds of embossing, the round (figure of Buddha, porcelain like, plaster model, the tang), polymer lighting and crafts such as painting, spray or screen printing, without affecting the original act the role of color or line under the premise of greatly improve its added value. Luminous ink color: transparent, red, blue, green, yellow and so on.

Why choose Photoluminescent films

Photoluminescent films are classified into inorganic glow in the dark vinyl roll films and organic Photoluminescent films.

Inorganic Photoluminescent film

Photoluminescent vinyl roll are represented by rare earth ion luminescence and rare earth fluorescence films, which have the advantages of strong absorption capacity and high conversion rate. Narrow band emission of Glow in the dark Self Adhesive Film is conducive to full color display, and their physical and chemical properties are stable. Because rare earth ions have abundant energy levels and 4f electronic transition characteristics, rare earth has become a treasure house of luminescence, providing luminescent films with superior performance for high-tech fields, especially for the field of Luminescent Self Adhesive Film information and communication. Common inorganic photoluminescent vinyl film take sulfide of alkaline earth metal (such as ZnS, CaS) aluminate (SrAl2O4, CaAl2O4, BaAl2O4) as luminescent matrix, and lanthanide elements (Eu), samarium (Sm), erbium (Er), neodymium (Nd) as activators and co-activators.

Traditional preparation methods of inorganic phosphor is the high temperature solid phase method, but with the quick update of the new technology, the improvement of luminescent film performance index to overcome the classic synthesis methods of inherent defects, some new method arises at the historic moment, such as the burning method, sol – gel method [, hydrothermal precipitation method, microwave method, etc. In the field of the photoluminescent self adhesive vinyl, organic films are increasingly brought to the attention of the people. Because there are many types of organic compounds, adjustable, rich colors, high color purity, molecular design is relatively flexible. According to the different molecular structure, organic light-emitting films can be divided into: These Photoluminescent film have their own characteristics in luminescence mechanism, physical and chemical properties and applications.
