Analysis of luminance and duration of luminous powder

rare earth photoluminescent pigment because of its long-lasting, non-radiation characteristics are more and more accepted by the industry and customers, but about the rare earth luminescent pigments brightness problems are often puzzled in new customers, the manufacturers say can clearly lit 10 hours, how a few hours out of sight, might think of a lie is not a manufacturer or product quality problems, which may cause some unnecessary misunderstanding. In this pair of glow in the dark pigment brightness [...]

Uv anti – counterfeiting phosphors use technical instructions, product characteristics

About uv anti-counterfeiting phosphors: L the special phosphor powder of this series of products presents white or nearly transparent color under the light source of visible light, and one or more fluorescent colors, including organic, inorganic, afterglow and other special effects, appear under the light source of different wavelengths (254nm, 365nm, 850nm), with bright and beautiful colors. L this series of products have a variety of colors including blue, red, yellow, green, purple, orange and pink. Product features: 1, inorganic phosphor l [...]

Luminous ink, paint preparation and use methods

When using luminous powder to mix paint and ink, in order to achieve the best luminous effect, the choice of paint or ink is very important. Choice of paint and ink: Has colorless and transparent, good light transmittance, especially good uv transmittance (i.e. no uv resistance). Varnish of organic solvent series. Resistant to light and weather and stable chemical properties. The surface adhesion of products to be painted is good (depending on the base material). In accordance with the above characteristics of paint or [...]

Rare earth long after glow in the dark powder knowledge

REE-activated alkaline earth aluminate, silicate and other high-tech self-luminous products. Their outstanding characteristics are: a variety of visible light absorption at 10 to 20 minutes, you can continue to light at night in the dark more than 12 hours, the luminous brightness and duration is 30 to 50 times the traditional ZnS glow materials. Glow in the dark powders main technical parameters: 1 initial brightness: glow powder under a certain light brightness (1000LUX), instrumentation brightness value between 0 (typically 3 seconds [...]

Photoluminescent pigment and polyvinyl chloride resin formulation

Polyvinyl chloride (PVC) 16-18% plus ring has 0%, hot melt after as puree. Wataru first ring B into the container, then add PVC. And with the added with partners. Upon completion of the addition, this container does not exceed 50 ℃ in hot water and dissolved with stirring 15 minutes, until the PVC fully dissolved, which is puree puree Photoluminescent pigment30% plus 100% stir for 30 minutes Become a luminous plasma, the other plus glow in dark powder varnish [...]

Ultraviolet invisible paint material pigment market prospect is broad

Invisible pigment is a kind of pigment: its characteristic is optical pigment material, light structure color matching principle. There are 18 colors. All the colors are in white shape. Under the irradiation of the purple lamp, all kinds of colors appear immediately and brightly. draw a pattern, day and wall a color, at night in the light, a vivid picture will appear! What is invisible illusory pigment? Invisible illusory pigment is a new high-tech pigment in today’s world. It has been applied in some [...]

Method for synthesis of long persistence materials

High temperature solid phase reaction method Long afterglow which was prepared by using high temperature solid instead should process is: according to the calculation of the mole ratio of says take spectrum pure co: A120, sr – and Eu203 raw material, and after a certain amount of canadians flux blending fine grinding, first by 1500 ℃ calcination 3 hours, then in the reduction of gas and 1200 ℃ 1400 ℃ roasting 2 one 4 hours, only made larger phosphor, hardness [...]

Instructions for the use of long-acting luminous powder, main technical indicators

Long-term luminous powder soil type belong to alkaline earth aluminate long afterglow luminescence materials, components can be expressed as: Al2O3 · (Sr, Mg, Ca) O: (Eu, La, Dy) B, can be in the sun or light absorbance 5-20 minutes later, will absorb the light energy stored in the crystal lattice, after can convert the energy into light energy in the dark and light, which can effectively sustained glow (luminescence brightness is more than 10 MCD/m2) to 8 to 10 [...]

Common USES of rare earth elements

Here we will talk about the timing of the application of various rare earth elements in order to make a better distinction between light rare earth and heavy rare earth: Promethium (Pm) : promethium is a man-made radioactive element produced in nuclear reactors. For vacuum detection and satellite to provide auxiliary energy. Pm147 gives off rays of low energy to make promethium batteries. Power for missile guidance instruments and clocks. The batteries are small and can last for years. Promethium [...]
