What is the form and material classification of the signs

Signs are very common in our daily life, but signs can be divided into wood signs, plastic signs and metal signs because of the different materials of production, dazzling, so how are signs classified? And what forms does it have? Material classification: (1) smooth logo: the picture or board surface is oily and very smooth. (2) acrylic marking: acrylic material as the main material on the board. (3) noctilucent material signage: noctilucent material signage (that is, we usually say the neon light) (iv) electric [...]

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 [...]

Types and development trends of commonly used water-based coatings

Water-based paint is a kind of paint with water as diluent. 70% -90% of the composition is water that is not harmful to human body and the environment. No organic solvent (such as benzene, ketone, ester, ether, etc.) is needed during the production process. Substances.) And formaldehyde, lead, chromium and other harmful substances. Water-based paint uses water as a dispersion medium. During the construction, water volatilizes and returns to nature in a vaporized state, without causing harm to human [...]

The main applications of rare earth luminescent materials

The use of rare-earth light-emitting materials will bring the effects of environmental protection and energy saving, good color rendering function and long life number to the light source, which is conducive to promoting the upgrading of products in the current significant area. Therefore, once the rare-earth light-emitting materials are created, they are quickly used in the production of color television picture tubes (CRTs) and fluorescent lamps. The industrial use of rare-earth light-emitting materials in China also began in the [...]

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 [...]
