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 [...]

The scientists obtained highly doped up-conversion nanoparticles

Recently, led by Australia’s Macquarie university professor da-yong jin advanced cell instrument laboratory and engineering college of Beijing university department of biomedical engineering XiPeng research joint research, found the new nano photonics light-emitting mechanism, and implements the high concentration of doping on the conversion of nanoparticles (Upconversionnanocrystals) technology, which shows the most sensitive nano fluorescent material yet. The paper was published in Nature Nanotechnology by Nature publishing group. Up-conversion nanoparticles, a new type of fluorescent material, are promising for a [...]

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 [...]
