Most modern buildings have begun to use large-area glass lighting, which gives us brighter rooms and wider views. On the other hand, the heat energy transmitted through the glass is farther than the surrounding walls, resulting in energy consumption of the entire building. Significantly increased. After decades of development, low-emission (Low-E) coated glass has been widely used in the construction field.
Low-E glass, also known as low-emission glass, is a film-based product that is coated with multiple layers of metal or other compounds on the surface of the glass. The coating layer has high transmission of visible light and high reflection of mid-range infrared rays, and has excellent heat insulation effect and good light transmittance compared with ordinary glass and conventional architectural coated glass.
UV targets used in the large-area coating industry are as follows:
