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 [...]
