The Manufacturing Method of Glow-in-the-Dark Paint

Night-lit paint is produced through a series of processes involving luminescent pigments, organic resins, organic solvents, and additives. The performance of night-lit paint is determined by its components, and the selection criteria for these components are crucial. 1. Selection of Resin and Varnish: A) After the luminescent paint forms a film, the particles of luminescent pigments achieve the light absorption function. Due to the light transmission requirement, the resin bonding the luminescent color material should have good transparency and no...

Preparation and application of photo luminescence ceramic glaze

The photoluminescent pigments can be directly used to make photoluminescent ceramic glaze.The following content provides some information on the preparation methods of photoluminescent ceramic glaze for reference. 1.The basic normal transparent ceramic glaze.The glaze should be ground thin and pass through 250 mesh sieve. 2.The photo-emissive pigment and the ceramic glaze were mixed in the ratio of 4:6 to make the luminous ceramic glaze. 3.During production, avoid contact between the luminescent pigment and metal materials, as it may affect the luminescence effect. The...

Configuration and Usage Instructions for Luminescent Plastics

1. Selection of resin: It is preferable to use powdered resin and one with a slightly higher melt index. 2. Selection of luminescent pigments: Type C or D are more effective. If the particle size is too large or too small, dispersion will be poor. 3. Selection of lubricants: For polyolefin resins (such as PE and PP), stearic acid amide should be used as the lubricant. For resins like ABS, PS, PC, AS, and PMMA, stearic acid salts should be selected, mainly including stearic...

Luminescent Ink Mixing Method and Usage Instructions

These are the guidelines for making photo-luminescent inks. Your application may require some adjustments to the following technical materials. Mix the photo-luminescent pigments into the transparent carrier. Any other pigments in the medium will blur the brightness. This type of photo-luminescent ink is suitable for various surfaces such as paper, textiles, wood, plastic, metal, ceramics, etc. The PL ink is composed of PL pigments, organic resins, organic solvents and solvent additives. How to make photo-luminescent ink: 1. The choice of resin. (1)Apply...

Contrast of zinc sulfide and strontium aluminate phosphor luminescent powder

What is traditional Zinc Sulphide pigment? Some of the first phosphors to be developed were inorganic zinc sulphide compounds. (German submarine commanders during World War I reportedly rubbed these compounds on their hands to read documents during blackout conditions.) These phosphors typically absorb energy from deep blue and ultraviolet light and emit it as yellow-green light.This is useful in that the peak spectral distribution of the emitted light roughly coincides with the peak spectral sensitivity of the human visual system...
