What glass is better for the light box of the bus shelter? Today, the intelligent bus shelter will share with you what glass is better for the light box of the bus shelter.
It belongs to safety glass. Toughened glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass bears external force, it first offsets the surface stress, so as to improve the bearing capacity and enhance the wind pressure resistance, cold and heat resistance and impact resistance of the glass. Pay attention to distinguish it from FRP.
When the glass is damaged by external force, the fragments will form small obtuse angle particles similar to honeycomb, which is not easy to cause serious harm to human body.
The impact strength of tempered glass with the same thickness is 3 ~ 5 times that of ordinary glass, and the bending strength is 3 ~ 5 times that of ordinary glass.
Tempered glass has good thermal stability, can withstand 3 times the temperature difference of ordinary glass, and can withstand the temperature difference change of 300 ℃.
Plexiglass is a popular name, abbreviated as PMMA. The chemical name of this polymer transparent material is polymethylmethacrylate, which is a polymer compound polymerized by methyl methacrylate. It is an important thermoplastic developed earlier. Plexiglass is divided into colorless transparent, colored transparent, pearlescent and embossed plexiglass. Plexiglass is commonly known as acrylic, Zhongxuan acrylic and acrylic. Plexiglass has the advantages of good transparency, chemical stability, mechanical properties and weather resistance, easy dyeing, easy processing and beautiful appearance. Plexiglass is also called gelatin glass, acrylic, etc.
Pearlescent plexiglass: it is made by adding pearlescent powder or phosphor to ordinary plexiglass. This kind of plexiglass has bright color and high surface finish. After the external form is hot pressed by the mold, even if it is polished, it still maintains the molded pattern, forming a unique artistic effect. It can be used to make figures, animal shapes, trademarks, decorations and publicity and exhibition materials.
Embossed plexiglass: it is transparent, translucent, colorless, brittle and easy to break. It is used in indoor doors and windows and other decoration. It has the characteristics of both light transmission and shape impermeability. It is usually used in indoor partition or doors and windows separating indoor rooms.
