Luminous powder
Luminous powder is a light-storing self-illuminating material that realizes the automatic light-emitting function in the dark by absorbing various visible light in a bright place, and can be recycled indefinitely. The product can be evenly distributed as an additive in various transparent media, such as rubber, plastic, ink, printing paste, paint, resin, glass, ceramic glaze, etc., to achieve the self-luminous function of the medium, showing good low-level illumination, indication Labeling and decorative landscaping effects. Luminous powder is environmentally friendly material, non-toxic, harmless and non-radioactive.

Luminous powder is environmentally friendly material, non-toxic, harmless and non-radioactive. Luminous powder is divided into two categories: short-acting luminous powder and long-lasting luminous powder:
1. Short-acting luminous powder (zinc sulfide luminous powder)
Chemical composition: ZnS.Cu
Product features: "Come fast, go fast". The so-called "getting fast" means that it is sensitive to the light source (short-time, weak light source can be effectively excited), and soon shows the luminous effect; "going fast" means that the rest of the glow time is short. It is easy to express the luminous effects, making it widely used in many industries and many products.
●Main varieties:
Ordinary powder: ordinary brightness
Envelope powder: It is effective against UV rays. The difference between the coated product and the non-coated product is that it is exposed to sunlight, and after a few hours, the non-encapsulated product will turn black.
High-gloss powder: all indicators reach the best level of the world's similar luminous powder
● Particle size: average particle size: 25-30um
● Color: Appearance color and illuminating color are yellow-green.
●Product quality (luminous brightness, stability) has reached the international top level. It has been OEM for the global distributor of zinc sulfide luminous powder. The company provides advanced testing equipment and staff to stay in the factory, which is stable to the quality of the company's products. Improvement has a positive effect.
● Compared with the long afterglow luminous powder, it has two remarkable features: it can be used in plastic products without blackening; it can be directly used in aqueous solvents.
2, long-lasting luminous powder (rare earth luminous powder)
Chemical composition: mixture AL2O3.SrO.Eu2O3.Dy2O3.B2O3.SiO2
Product features: "Come slow, go slow", the so-called "slow" means that it takes a long time to illuminate the light, in order to better express its luminous effect; "going slow" means that the rest of the glow time is long and the longest Up to ten hours. The high brightness and long time of the light make it extremely practical. In addition to decorative applications, it is also widely used in safety, fire, military, electrical and other fields.
●Main varieties:
Conventional luminous powder: the appearance color is yellow-green, and the corresponding luminous colors are yellow green light, blue green light and sky blue light. Among them, the luminous effect of yellow-green light is the best, followed by blue-green light. Long-lasting luminous powder has various subdivisions according to brightness level and particle size.
Color luminous powder: It is a derivative of conventional luminous powder, which is prepared by adding fluorescent pigment to conventional luminous powder. After coloring, the appearance color of the conventional luminous powder is changed, but the luminous color cannot be fundamentally changed. After adding color, the luminous effect will be greatly reduced, and the heavier the color, the more the drop. It is recommended to use blue-green light or sky blue luminous powder to prepare blue luminous powder, and other colors to choose yellow-green luminous powder.
● Brightness: There are many grades according to the brightness.
● Average particle size: There are various particle size divisions in the range of 3-165 um.
●Color: The appearance of conventional luminous powder is yellow-green, and the luminous colors are yellow-green, blue-green and sky-blue. Color luminous powder is a derivative of primary color luminous powder, which is orange red, peach red, yellow, blue, green and purple.
●The quality of domestic long-lasting luminous powder (luminous brightness, stability) is in an international leading position.
●Long-term luminous powder can not be directly used in aqueous solvents. If it is necessary, please declare it, and it can be used after micro-encapsulation treatment.
● Long-lasting luminous powder used for injection molding will have blackening phenomenon and is inevitable. Reasonable application can alleviate this phenomenon.
