Description
Technical Field
The utility model belongs to the technical field of magnetron sputtering coating film, concretely relates to two silver low-emissivity coated glass of panorama grey.
Background
As a novel building and decoration material, the Low-E glass has the characteristics of high visible light transmission and high mid-far infrared ray reflection of a coating layer, so that compared with common glass and traditional coating glass for buildings, the Low-E glass has the following obvious advantages: 1) the heat loss of the outer door and window glass is the main part of the energy consumption of the building, and accounts for more than 50 percent of the energy consumption of the building. Compared with a common-structure white glass door and window, the low-emissivity coated glass can reduce the energy loss of the part by 60-90% according to different film layer structures. 2) Good optical performance. The Low-E glass has high transmittance of visible light in sunlight, and can reach more than 80%. And the reflectance is very low, which makes the optical performance of the coated glass much improved compared with the traditional coated glass. The appearance is more transparent and clear when the glass is seen from the outside. Not only ensures good lighting of buildings, but also avoids the phenomenon of light pollution caused by light reflection of the traditional large-area glass curtain wall and hollow glass door and window, and creates a softer and more comfortable light environment.
According to the analysis of the recent market sales situation, the gray low-emissivity coated glass is more and more approved by the market at present, and the demand of gray products is more and more vigorous. However, with the gradual mature and popularization of the technology, homogenization competition is more and more obvious, and the requirement of customers on the appearance color of the curtain wall is higher and higher. In terms of the actual installation effect of curtain wall glass, because the wall area is large, the building floor is high, the observation angles of the glass at different positions of the curtain wall are different when the curtain wall is observed in a close range, and for double-silver low-radiation coated glass, because of the interference of multilayer films and the influence of transmission colors, the colors of the glass are different when the glass is observed at different angles, the integral color of the curtain wall is inconsistent, the decoration effect is influenced, and meanwhile, the indoor color decoration is poor due to excessive pursuit of outdoor colors of many products, and the difference with the outdoor color exists. The prior art has the following disadvantages:
1) the existing double-silver low-emissivity coated glass mainly deflects to the blue system and the green system.
2) The existing double-silver film system generally has the phenomena of small-angle color change and large difference of indoor and outdoor colors.
