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 [...]

Progress has been made in the study of luminescence mechanism of long-afterglow luminescent materials

Source: powder circle (www.360powder.com) – the circle of business and life of people in the powder industry! Long afterglow materials commonly known as noctilucent materials or light-storage luminescent materials, in the visible or ultraviolet light excited, can maintain dozens of minutes to dozens of hours of continuous luminescence. This kind of material has wide application value in the fields of low-light lighting, emergency instruction, information storage and display, energy-saving building, intelligent transportation and so on. CaAl2O4:Eu,Nd is a typical blue-purple [...]

Crystal growth and luminescence characteristics of powder electroluminescent materials

The effect of Cu~+ on the luminescence characteristics of ZnS: Cu electroluminescent materials was studied. The effects of burning temperature and flux on the structure, particle size and luminescence characteristics of luminescent materials were discussed. The luminescence properties of powder electroluminescent materials were improved by phase change technology and doping of two activators. The study shows that the luminance of the materials increases with the increase of the doping amount of Cu+. When the doping concentration of Cu+ is [...]

Manufacturing method of luminous acrylic switch

The switch installed in the 86 box on the wall is widely used as a control operation facility to control the lighting and extinguishing of indoor lamps. The disadvantage of the wall switch that is commonly used now is that it is not easy to find without other auxiliary light sources in the night, and because the pressure plate of the wall switch that is commonly used now is small, it is easy to fall or collide in the [...]

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 [...]
