Luminous powder is a special pigment that glows in the dark. It has a unique crystal structure and excellent light absorption, energy storage and luminescent properties. It absorbs visible light and stores light energy under natural or artificial light, then slowly releases it as fluorescent light in darkness to achieve persistent luminescence.

Characteristic

1. Light absorption and light storage ability: Luminous powder can absorb and store light energy under light conditions, and then continuously release it in the form of visible light in the dark. The luminous time can reach more than 8 hours or even more than 12 hours.

2. Luminous life: The luminous life of luminous powder can be as high as more than 20 years, and it has an extremely long service life.

3. Environmental protection characteristics: luminous powder does not contain any radioactive substances, is non-toxic, harmless, non-burning, does not contain phosphorus, lead and other harmful elements, is safe for human body and conforms to the concept of green life.

4. Physical and chemical stability: Luminous powder has stable physical and chemical properties, adapts to various environments, and ensures high brightness display and long-term luminous effect.

Application Fields

Luminous powders are widely used in a variety of fields, including but not limited to:

Plastics, Rubber & Leather Industry: Used in the production of luminous switches, buttons, handles, toys, crafts etc.

Ceramics, Enamel & Glass Industry: Used for fire prevention, safety warning signs, road signs and etc.

Paints & Coatings Industry: Used for traffic road markings, interior and exterior decoration of buildings etc.

Crafts Industry: Used in luminous art paintings, luminous glass products etc.

Special Printing Industry:   Luminous ink, printing paste etc.

Making Methods and Application Skills

Luminous powder can be combined with a variety of varnishes and resins to make luminous paint. When using, you can mix the luminous powder with varnish, then shake it vigorously and then spray it or apply it by hand on the surface of the machine. The proportion of luminous powder in the varnish is 20%-60%, and the concentration can be adjusted as needed. In addition, the precipitation rate of luminous powder is fast, and it is necessary to operate quickly during spraying to avoid blocking the nozzle.

Afterglow test method:

The luminous powder is placed under a D65 light source with a height of 15cm; Irradiation for more than 10 minutes. Then put it in a dark place, and the afterglow is slowly released. The time for the naked eye to see the bright light is 8-12 hours, which is about 0.25mnd/㎡
