Luminescent plastic configuration and instructions for use

1. Selection of resin: Had better choose powdery form resin, with the resin with melting index a bit taller relatively. 2. Selection of luminous pigments: Type C or D is more effective, and the particle size is too large or too small for dispersion. 3. Selection of lubricant: stearate amide should be used as lubricant for polyolefin resin (such as PE, PP). ABS, PS, PC, AS, PMMA and other resins should choose stearate, mainly zinc stearate and magnesium stearate. 4. Selection of dispersant: The choice of...

How to make photoluminescent printing paste?

These are the guidelines to making photoluminescent printing pastes. Your application may require some adjustments to the technical material below. Mix the Photoluminescent pigment into clear vehicles. Any other pigment in the medium will obscure the luminosity. Choose neutral or alkalescent clear/transparent printing paste and the suitable photoluminescent pigment, the percentage of the photoluminescent pigment is normally 10-50%, making it well proportioned by mixing and churning up. You can use relevant thinner to adjust the viscosity. Before printing the...

Luminous Printing Ink Mixing Method and Direction for Use

These are the guidelines to making photoluminescent printing ink. Your application may require some adjustments to the technical material below. Mix the photoluminescent pigment into clear vehicles. Any other pigment in the medium will obscure the luminosity. Such photoluminescent printing ink is suitable for many surfaces such as paper, textile, wood, plastic, metal, ceramic, etc. The PL printing ink comprises PL pigment, organic resin, organic solvent and solvent assistant. How to make photoluminescent printing ink: 1. The choice of resin. (1)Apply...

Experiment of preparing long afterglow materials by combustion method

Experiment part: Objective: Learn to use the combustion method to rapidly grow the afterglow materials. Understand long afterglow material and its long afterglow principle. Learn to rapidly synthesize inorganic oxides and nanomaterials by combustion method. The synthesis method of long afterglow materials and the related steps of combustion synthesis experiment Experiment principle: Combustion is also called self - propagating high - temperature synthesis. It is a kind of chemical system with high exothermic heat induced local chemical ignition through external energy, forming frontier...

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...

Photoluminescent Pigment Production Technic Process

Phosphor is a special crystal structure luminescent material, which has a strong absorbance - STORING - luminous ability, when illuminated by natural light and the light, that part of the light energy is absorbed and stored, and then in the form of visible light in the dark Slowly release the luminescent material after five minutes after the light in the dark can automatically light for more than 12 hours of light absorption process can be repeated countless times glowing,...
