When it comes to luminous powder, many people think of fluorescent brighteners, but they are actually different. Below, fluorescent brightener manufacturers will introduce what luminous powder is.
Luminous powder, also known as luminous powder or night light powder, is called night light powder because its luminous intensity is much weaker than that of sunlight and light, but it will be "brighter" in darker environments.
The luminous powder can be divided into two types:
1. Self luminescent luminous powder, which does not require illumination and is excited by particles released during the transformation of some chemical elements it contains, can emit uninterrupted, uniform, and stable light, and generally last for more than six months.
2. Light storage luminous powder, which requires light sources such as sunlight and long wavelength ultraviolet light to shine for a short period of time and then turn off the light source to continuously emit light for a period of time.
The cost of self luminescent luminous powder is high, and radioactive elements can cause certain harm to the human body, which has gradually faded out of the market.
