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 [...]

Introduction of various types phosphorescent materials

Phosphor types use a phosphor “phosphor” “Inorganic powder material at a certain excitation conditions can be light, sometimes also called light pink, crystalline phosphors or phosphor according to the type of excitation mode can be divided into organic light-emitting phosphor, the electroluminescent phosphor, cathode ray luminescent phosphors and phosphor luminescence radiation and so on. 2 photoluminescent phosphors “photo luminescent phosphor” Emitting excitation light can be an inorganic powder material. Excitation light can be ultraviolet, visible, near-infrared bands. 3 fluorescent high pressure mercury lamp phosphors [...]

Use of invisible mural materials, production methods and tools

Methods and tools for making invisible murals Invisible murals (also known as fantasy invisible murals, magic invisible murals, fantasy angels, etc.) The method of making it is the same as the tools needed for making it. It’s just different levels The tools and raw materials are not the same as haotian space technology as the domestic invisible murals production technology Technology, professional development of r & d team has been developed according to the market needs of the first two After the third and [...]

Examples and formulations of application of luminous powder in coatings and inks

May be mixed with a variety of transparent resin coatings and ink to make the glow in dark paint or inks. Such resins include acrylic resins, urethane resins, epoxy resins, amino resins, polyvinyl butyral resins, polyamide resins, etc., in coatings used in a proportion of 10% -50%, the proportion of the ink is 30% to 60% as well, the above-mentioned resin is dissolved with an appropriate solvent, adding luminescent pigment, and then adding a suitable anti-settling agents, antifoaming agents, [...]

Screen printing photoluminescent safety sign Caution

photoluminescent safety sign need to use photoluminescent printing ink, photoluminescent printing ink used in the signage industry, manufacturers are generally used according to their intended use and signage products themselves formulated to get the best use of effects and economic costs. Usually adding a certain percentage of the ordinary transparent ink photoluminescent materials by simple mixing process can be made luminous ink use, if stored for a period of time sufficient to facilitate wetting photoluminescent materials inks, printing products resulting [...]

How to distinguish luminous powder and fluorescent powder

Luminous and phosphor are the two products, but many people think that is luminous phosphors and think they are following the same substance, small to give you how to distinguish luminous powder and phosphor.: 1 luminous powder: Yes absorbance – STORING – a self-luminous light emitting material, which is a kind of luminous material can be made visible in the dark, called luminous powder, luminous powder it into long-term, short-acting luminous, radioactive luminous, but they are of a material glowing [...]
