Product overview: 

luminous powder is a kind of powder photoluminescence material, which can realize the luminescent function by absorbing various visible light, especially for the short wave visible light below 450 nm, and can be recycled for many times. As an additive, it can be widely used in various transparent media such as coatings, inks, paints, plastics, printing pastes, ceramics, glass, fibers, etc. The pigment presents its own appearance color in the bright place, while it emits light of different colors in the dark place, showing good functions of low-level emergency lighting, indication signs and decoration. All kinds of luminous products made of the pigment can be safely used in daily consumer goods such as clothing, shoes and hats, stationery, clocks, switches, signs, fishing gear, toys, handicrafts and sports goods. And in building decoration, transportation, military facilities, fire emergency system, such as: import and export signs, escape route indication system has a good role.

Phosphor (commonly known as luminous powder), luminous energy storage luminous powder is phosphor in the natural light, sunlight light, ultraviolet light, etc., after the light is stopped, slowly released in the form of fluorescence, so at night or in the dark, can still see light, lasting for several hours to more than ten hours.

Luminous powder is a kind of luminescent material with special crystal structure. It has the ability of absorbing light, storing light and emitting light. When it is irradiated by natural light and light, it absorbs and stores part of light energy, and then slowly releases it in the form of visible light in the dark. After 5 minutes of illumination, the luminescent material can automatically emit light for more than 12 hours in the dark. The process of light absorption and luminescence can be repeated countless times, and the lifetime of luminescence is more than 20 years.

characteristic:

1. The excitation time is short, the luminescence and afterglow time are long, and the brightness is high.

2. Extremely stable physical and chemical properties, strong environmental adaptability, long service life.

3. The particle size is small, and the fineness and particle size distribution are uniform.

Attention:

1. Avoid using in acidic environment (Al2O3 will react with acid in neutralization).

2. Avoid contact with water and keep it sealed as far as possible; (it will absorb moisture in the air, making luminous powder black, not luminous and caking).

3. Avoid contact with metal (it will affect the unsaturated state of luminous powder and affect the luminescence).

4. Avoid high temperature and high speed friction (which will change the existing structure of luminous powder).

5. The pigment ratio is large, so attention should be paid to mixing well when using, and easy to precipitate.

6. The hardness of luminous powder is relatively high. Friction occurs between luminous powder and metal in the process of mixing. The oxide layer on the metal surface is black. After friction, it is mixed in the ink and printing paste to make it black. Therefore, it is necessary to avoid contact with metal in use.

7. Luminous powder is composed of fine particles with various particle sizes, which can not be dissolved in ink and printing paste.

8. The particle size of luminous powder should be selected for printing. The thicker the luminous powder of the same brightness level, the better the luminous effect. However, when the particles are coarse, the coating surface will be rough and the coating surface is relatively thick, which will have a certain impact on the fastness. Fine patterns need to use a bit thinner luminous powder.

The more transparent the resin is, the better the luminous effect is.

Application fields:

In real life, people make use of the characteristics of luminous powder for a long time to make weak light source, which has special use in military departments. This material can be applied to aviation instruments, clocks, windows, machines, various switch signs, door handles, etc., and can also be pressed into various symbols, components and articles (such as power switch, socket, fishing hook, etc.) with various transparent plastic materials. After being illuminated by light, these light-emitting parts still emit light continuously at night or after accidental power failure or lightning, so that people can distinguish the direction around them and bring convenience to work and life.
