Application of luminous powder rolling process

Calendering A method of forming a luminescent powder continuously into a film or sheet. In the rubber processing process, the luminous powder and the rubber compound can be calendered into a film of a certain thickness and width, or the pattern can be pressed on the film for the formation of the next product. The calendering method is also used to hang the fabric and the steel cord, and to bond the film to the film, the film and [...]

Inkjet printing luminous film instructions

Inkjet printing luminous film (luminous paper, luminous photo printing film) Is a new generation of luminous digital output material, high resolution can be directly printed photos. This product has been tested by the relevant departments of the state, and it is non-radioactive, non-toxic and harmless. It is the only green energy-saving high-tech product that can emit light at night and display its contents without consuming electricity. After 5-15 minutes of visible light, the product can spontaneously light in the dark for [...]

Luminescence mechanism of long afterglow luminescent materials

Hole transport model For this type of material, the earliest model was the hole transport model proposed by Matsuzawa et al. in the SrAl2O4:Eu, Dy system. Based on this model, Matsuzawa believes that in the long afterglow materials SrAl2O4:Eu, Dy, Eu is the electron capture center and Dy is the hole trapping center. When the material is excited by UV, Eu can capture electrons to become Eu, and the resulting holes are captured by Dy through the valence band to [...]

Luminous powder silica coating modification treatment

Water-based luminescent powder is modified by silica cladding on SrAl2O4: Eu2+ and Dy3+ long afterglow luminescent powder by chemical precipitation method, which can effectively improve the water resistance of luminescent powder, but has little effect on the long afterglow luminescence characteristics of luminescent powder. Emulsion paint with modified luminescent powder has the advantages of storage stability and good water resistance. Luminescence performance before and after modification of luminescent powder: the peak types and peak positions of the excitation and [...]

From the aristocracy to the common people – new captain afterglow luminous materials

Long Persistent Luminescence (LPL) material is also known as luminescent Luminescence material, commonly known as luminous powder or Long afterglow powder. Its luminescence principle is photoluminescence, that is, when excited by the light source, the excitation energy is stored in the excited state. When the excitation stops, the energy is slowly released in the form of light. In 1996, Matsuzawa et al. published a strontium aluminate (SrAl2O4) system doped with europium (Eu) and dysprosium (Dy), with a decay time [...]

Invisible mural paint, invisible photoreceptive murals have broad market prospects

UV phosphors, UV powders, and invisible photo murals are the latest in the entertainment industry. Invisible paintings are popular in Europe, America, Japan, South Korea, etc., and are still blank in the domestic market. Such a large Chinese entertainment and leisure venue and home decoration market, the prospect of invisible painting is extremely attractive. At present, the entertainment industry in mainland China is developing rapidly, the decoration grades are constantly improving, and the customers’ requirements for the atmosphere of [...]

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 [...]
