Glow powder can be in the dark automatically glow material, the main component is rare earth, belongs to the inorganic class of materials. First absorb all kinds of light and heat, converted into light energy storage, and then in the dark automatically glow, by absorbing all kinds of visible light to achieve the glow function, and can be used for an unlimited number of cycles. So how should you identify the quality of glow powder? Here is a small introduction to everyone.
1. First take out the glow powder, placed on the desktop, carefully look at whether there is no plus actually impurities in it, you can use a magnifying glass to see more obvious.
2. Glow powder particle size and glow powder brightness is directly related to the glow powder, the larger the glow powder particles, the brighter the glow effect, the smaller the glow powder particles, the darker the glow effect, so the choice of glow powder also depends on what industry they use, there is no great requirement for the particle size, no then it is recommended to choose a thicker glow powder so that the glow effect is more obvious.
3. Several particles of relative size of the glow powder laid flat on a black plate or desktop (so that the test can be a closed room or night test). Put in the daylight under close light (it is recommended to use violet light) for about 10 seconds. Then turn off the light to compare the brightness. See which light absorption effect is fast. Good glow powder absorb light faster than ordinary glow powder, absorb light effect is very obvious.
Glow powder is a very small diameter of the substance, the powder is relatively soft, so commonly used in the processing and production of paint spray paint, many people worry about glow powder is not toxic, in fact, modern processing and production of glow powder after testing are non-toxic and harmless, and will not produce explosive substances.
We can choose a variety of colors to match other substances to deploy glow powder, absorb light source is also very wide, light and sunlight or scattered light after irradiation itself material absorption can be achieved after the storage of light and issued. This is a cycle of absorption and release of light process.
According to the nature of glow powder, the larger the general glow powder particles also means that the glow powder glow brightness is better, the surface is also more shiny, but the key to choosing glow powder does not lie in the brightness, to combine the specific manufacturing process to choose glow powder. Because the nature of the glow powder itself can be soluble in water, and in acidic substances are easier to decompose, in order not to destroy its own nature recommended glow powder do not randomly into the mixed water and acidic substances.
