Introduction to the classification principle of thermochromic paint

Most of the products around us are classified according to color or specifications, but the performance characteristics of thermochromic paints explained today are more prominent, and the performance effects are more characteristic, because they can change colors according to different temperatures. . For example, in places where the temperature difference between day and night is large, or where the requirements for personalization are more stringent, you can find that thermochromic paint can have a decorative effect. For example, some [...]

Up-conversion process and mechanism of up-conversion luminescent materials

Its principles include excited state absorption (ESA), energy transfer up conversion (ETU), and photon avalanche (PA). Energy transfer refers to the coupling of two excited ions with similar energy through a non-radiative process, one of which transfers energy to the other and returns to a low energy state, and the other ion receives energy and transitions to a higher energy state. Energy transfer upconversion can occur between the same ions, or between different ions. Therefore, energy transfer up-conversion can [...]

What factors will affect the luminous effect of glow in dark powder printing

Glow in the dark powder printing has become very popular in recent years. Many clothing printing factories have luminous powder printing technology, and luminous clothes are also very popular in the market. Some manufacturers’ technology is not enough, so the printed products have unsatisfactory results. So what are the factors that affect the luminous powder printing effect? Some factors that determine the luminous effect of luminous powder 1.Transparency of ink The luminous effect of the luminous powder of the luminous ink depends on [...]

Application of thermosensitive color change powder in ink

1 selection of connecting material (resin) : 1.1 influence of viscosity and solid content of binder (resin) on color concentration and surface gloss: The choice of resin in ink oil has a very important effect on the color concentration and surface gloss of temperature-varying ink, which is more significant for black ink. Because the content of pigment in the color changing ink is much higher than ordinary ink, if the resin modulation of ordinary ink color changing ink will lead to [...]

The difference between electroluminescence and photoluminescence

1. Electroluminescence is different from photoluminescence in that electroluminescence refers to electroluminescence and photoluminescence refers to the luminescence of photoluminescence materials. The principles of electroluminescence and photoluminescence are different. 2. Electroluminescence, also known as electric field luminescence, or EL for short, is a physical phenomenon in which the electrons excited by the electric field hit the light center by the electric field generated by the voltage applied to the two electrodes, resulting in the transition, change and compound of electrons [...]
