Use method of reflective powder and reflective glass microbeads

Is the use of the reflective glass beads according to the actual needs of customers, according to different purposes, luminous intensity and the different requirements, in the actual production summary for its technical solutions, in the process of reflective glass beads is according to its luminous intensity, the length of the afterglow time, and determine its quality and cost, the following content is for reference only. Usage of reflective glass microbeads: Water-based screen printing method 1: Reflective glass beads can be directly [...]

Research status of fluorescent materials

1. Doping modification: Other ions are added to the traditional fluorescent materials to increase the conversion efficiency and enhance the fluorescence intensity. For example, add the sensitized Yb3+ ions to the fluorescent material. Yb3+ ion has a strong absorption cross section near 980nm, and only has two energy levels, so it will not lose the excitation light energy due to the up-conversion process. Therefore, it is an ideal sensitizer. In particular, lithium ions enhance the fluorescence of rare earth [...]

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 [...]

Intaglio master years of work summary

Preparation of gravure printing press Check whether there is dust, garbage and other things not related to printing around the printing press, and check whether the ventilation and exhaust facilities are in good condition. Check whether the raw and auxiliary materials are fully prepared and meet the printing requirements. The printing of plastic film, the requirements of the substrate film to be printed in accordance with the following requirements: smooth and flat surface, no obvious stiff block, yellow and black spots, [...]

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 [...]

Characteristics of zinc sulfide short – acting noctilucent powder

Zinc sulfide short – acting luminous powder: product features: “come quickly, go quickly”. The so-called “coming fast” refers to the light absorption time is short and sensitive to the source of light, quickly show a luminous effect: “going fast” refers to its short afterglow time. It is easy to show the characteristics of luminous effect, which makes it widely used in many industries and products. Advantages of short-acting noctilucent powder: easy to perform noctilucent effect, the initial brightness is [...]

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

In the dark night, a shiny watch can save a lot of trouble. Many watches will be coated with luminous paint on the hands and scales, so that people can watch at night. After more than a hundred years of evolution, the luminous material of the watch has undergone earth-shaking changes. Do you know if these materials are harmful to the human body? Today, let’s take a look at the paint of luminous watches. Rolex uses the innovative Chromalight luminous display on the new [...]

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 [...]
