Uv fluorescent ink product introduction

Ultraviolet fluorescent ink is one of the most mature anti – counterfeiting inks in the market, in the ink to add the corresponding visible fluorescent compounds and made. The ink is printed with a fluorescent color that can be excited by ultraviolet light at 365nm (long wave) or 254nm (short wave) wavelengths. According to the different excitation light source, can be divided into long wave fluorescent ink, short wave fluorescent ink and double band fluorescent ink. According to the form [...]

The difference between long-acting luminous powder and short-acting luminous powder

Many friends should have used or heard of overnight luminous powder, but don’t know the difference between long-acting luminous powder and short-acting luminous powder. In order to make it easier for everyone to distinguish, choose the product that suits you for the following reasons Advantages and disadvantages of short-acting luminous powder 1. Zinc sulfide short-acting luminous powder has a short luminescence time, and it can only emit light for half an hour at most once it is stored. 2. Zinc sulfide short-acting [...]

Application scope and production status of reflective powder

Reflective powder: it is produced from a glass based powder material. Its main components are SiO2, CaO, Na2O,TiO2 and BaO. The product can be added directly to a coating or resin to give the product a retro-reflective effect and can be used on a variety of complex shaped surfaces. It is the production of reflective cloth, reflective film, reflective coating, reflective signage, advertising materials, clothing materials, standard racing track, shoes and hats, school bags, water, land and air life-saving [...]

LED phosphors: a brief introduction of several phosphors

Ⅰ. Yellow phosphor powder Yellow Phosphors 1. Introduction: YAG phosphor is the fluorescent material of white LED. A blue light chip is coated with a layer of fluorescent substance, and a blue light LED is used to illuminate the fluorescent substance to generate complementary yellow light with blue light. Then the complementary yellow light and blue light are mixed with the principle of lens, and the white light required by the naked eye can be obtained. 2. Product Performance 2.1 The Appearance [...]

Which watchmaking brands have glow-in-the-dark watch patents

Originally used in watches, noctilucent materials were invented by Panerai. At this time panerai will also be the invention of the patent named their own watch series. There are a lot of friends private message we said before the network spread the kind of watch luminous material, is it true that the radioactive statement, let us take this question together to discuss about the watch luminous material behind the story. Noctilucent material is the most comfortable application in the diving [...]

There are three common forms of electroluminescence

Gas discharge light source has the following common characteristics: (1) high luminous efficiency. D4101da-r is 2 to 10 times more efficient than incandescent lamps of the same wattage, so it has the characteristics of energy saving. (2) compact structure. The electrodes can be made strong, compact, vibration-resistant, and shock-resistant because they do not emit light from the filament itself. (3) long life. General than incandescent lamp life 2 ~ 10 times longer. (4) strong light and color adaptability. Can vary over a wide [...]

Market demand analysis of rare earth luminescent materials in China

(a) the change of market demand for energy-saving lamps 1. The trend of energy-saving lamps replacing incandescent lamps and halogen powder lamps is significant In view of the outstanding functions of energy-saving lamps in terms of light efficiency and longevity, a number of countries and regions around the world have successively launched programs to stop the use of incandescent lamps and promote the use of energy-saving lamps in recent years under the background of global response to climate change and power [...]

Luminous “toxic”? Talk about the knowledge of luminous watches

The difference between pearl powder and onion powder

1. The pearl powder The unique soft pearl luster of pearl powder has incomparable effect. Special surface structure, high refractive index and good transparency make it in transparent medium, creating the same effect as pearl luster. The excellent chemical, thermal and mechanical properties of pearly powder make it possible to be widely used in paints, inks, plastics and many other fields. They provide a whole new color quality for these products. Pearl powder is harmless to human body. So it can [...]

What is the form and material classification of the signs

Signs are very common in our daily life, but signs can be divided into wood signs, plastic signs and metal signs because of the different materials of production, dazzling, so how are signs classified? And what forms does it have? Material classification: (1) smooth logo: the picture or board surface is oily and very smooth. (2) acrylic marking: acrylic material as the main material on the board. (3) noctilucent material signage: noctilucent material signage (that is, we usually say the neon light) (iv) electric [...]
