The difference between long-lasting color luminous powder and short-acting color luminous powder

The long-lasting color luminous powder has more than ten times of afterglow time than the short-acting (ordinary) luminous powder. The main component is rare earth aluminate, which is stable in physical and chemical properties, so it has good weather resistance and can be used indoors and outdoors.

 The taboos for long-lasting luminous powder use the following three points:

 1. Prevent contact with water, and the luminous powder that has not been treated with water is decomposed by water, which affects performance.

 2. Prevent direct contact with metals, and do not come into contact with metals, especially iron, which can cause blackening.

 3. Prevent excessive high temperature and direct friction. Normal type luminous powder has no such contraindications.

The long-acting color luminous powder has a specific gravity of 3.2-3.6, the material is rare earth element, the material itself, does not contain radioactive substances, has long absorption time and long light-emitting time.

The short-acting (ordinary) luminous powder has a specific gravity of 4.1 and the material is zinc sulfide: copper (ZnS: Cu), and the light absorption and light-emitting time are short.

Long-lasting color luminous powder can be used to display night objects, clocks, phone buttons, buttons, field instruments or indicators, radios, camera theater seat numbers, traffic signs, general decorations, clothing products, power switches, fishing equipment, construction Decor, fire emergency escape system identification, military equipment, aircraft and other transportation tools use... and so on, long-lasting luminous powder is used more.
