Dimming glass for building exterior wall decoration materials

Abstract

The invention discloses a dimming glass for building exterior wall decoration materials. The dimming glass comprises a near-light layer glass and a far-light layer glass; a closed layer is formed between the near-light layer glass and the far-light layer glass at intervals; cylindrical strips are arranged in the closed layer from top to bottom, and the cylindrical strips are connected sequentially; the cylindrical strips are arranged horizontally, and the cylindrical strips are tangent to the near-light layer glass and the far-light layer glass; the closed layer is in a vacuum state; the side walls of the cylindrical strips are provided with grooves; the grooves are parallel to the axis lines of the cylinder strips. The dimming glass can effectively regulate the light transmittance rate and reduce the sunlight intensity which is too high in summer, and the installation of a vacuum cavity can have good effects of thermal insulation and sound insulation, thereby improving the thermal insulation performance of the dimming glass, so that the dimming glass can meet the use of building exterior walls.

Description

technical field [0001] The invention relates to a switchable glass, in particular to a switchable glass used as a building exterior wall decoration material. Background technique [0002] Dimming glass, also known as atomized glass, electronically controlled glass, intelligent dimming color-changing glass, electric curtain, atomized glass is a kind of intelligent high-end functional glass. The structure of the dimming glass mainly includes a liquid crystal dimming film (also called PDLC) and transparent glass fixed on both sides of the liquid crystal strip light film. By energizing the liquid crystal dimming film, the power can be cut off, and the scattering of the dimming glass can be controlled ( Transmissive (opaque) state and transmissive (transparent) state, this change achieves the dual requirements of glass permeability and privacy protection, making it widely used. Switchable glass itself not only has all the characteristics of safety glass, but also has the privacy...

AI Technical Summary

Problems solved by technology

Due to the dual constraints of float glass and PDLC on its light transmittance, there is a problem that the visible light transmittance is generally lower than 70% in the electrified state, which greatly limits the popularization and application of dimming glass

At the same time, the existing dimming glass has poor heat insulation performance, especially in summer, when the outdoor temperature is high, the existing dimming glass cannot prevent heat from entering the room.
