Description

Technical Field

[0001] The utility model relates to a three-silver plus silver-free hollow glass, belonging to the technical field of functional glass. Background Art

[0002] Recently, with the improvement of national policies and energy-saving requirements, the change of designers' concepts, people's requirements for energy saving and low carbon are getting higher and higher. Then the glass deep processing industry launched three-silver products, high transmittance, low shading products to match national policies and design concepts. In order to reduce the cost of owners and curtain wall companies, it is necessary to change from the original three-glass two-cavity to a single-cavity hollow, and it must also meet the thermal insulation effect of the overall curtain wall. The K value of the single-cavity filled with argon relying solely on the three-silver technology can only reach about 1.35W / ㎡.K, which still cannot meet the designer's K value requirements for the overall curtain wall. The K value of the glass single cavity is only around 1.0W / ㎡.K to meet the overall insulation effect. Utility Model Content

[0003] The utility model aims to provide a triple-silver plus silver-free hollow glass to solve the above technical problems.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A triple silver and silver-free insulating glass comprises an outer layer of triple silver coated glass and an inner layer of silver-free coated glass; a warm edge spacer is provided between the triple silver coated glass and the silver-free coated glass;

[0006] The triple-silver coated glass comprises a first float substrate and three silver film layers coated on the surface of the float substrate, wherein the structure of the three silver film layers is as follows: the second layer is SiNx, the third layer is a dielectric layer NiCr, the fourth layer is a metal conductive layer ZnAlOX, the fifth layer is a functional layer Ag, the sixth layer is a metal conductive layer ZnAlOX, the seventh layer is a dielectric layer NiCr, the eighth layer is SiNx, the ninth layer is a dielectric layer NiCr, the tenth layer is a metal conductive layer ZnAlOX, the eleventh layer is a functional layer Ag, the twelfth layer is a dielectric layer NiCr, the thirteenth layer is a metal conductive layer ZnAlOX, the fourteenth layer is a functional layer Ag, the fifteenth layer is a metal conductive layer ZnAlOX, the sixteenth layer is a dielectric layer NiCr, and the seventeenth layer is a ceramic top layer ZrO;

[0007] The silver-free coated glass comprises a first float substrate and a silver-free film layer coated on the surface of the float substrate, wherein the structure of the silver-free film layer is as follows: a second SiNx film layer, a third niobium oxide film layer, a fourth TiO2 film layer, a fifth ZrO layer, and a sixth graphite carbon layer.

[0008] A further improvement of the technical solution of the utility model is that the triple-silver coated glass includes a first layer of a float substrate which is an ultra-white float substrate.

[0009] A further improvement of the technical solution of the utility model is that the film layer of the triple-silver coated glass and the film layer of the non-silver coated glass are both located on the indoor side of the float substrate.

[0010] Due to the adoption of the above technical solution, the technical effects achieved by the utility model are:

[0011] First of all, the outer side of the glass is triple-silver coated glass, which has the effect of high light transmittance and low sunshade, which ensures sufficient light indoors and extremely low sunshade. When the sun is shining brightly outside, the indoor room is warm like spring without any burning feeling. The film layer is fully utilized to block the incident sunlight, which not only meets people's needs for lighting, but also meets people's needs for sunshade.

[0012] Secondly, the inner side of the glass is silver-free coated glass, which has the advantage of high transmittance of visible light, ensuring sufficient light entering the room after passing through the three-silver coating. At the same time, it has a very good emissivity, reducing heat conduction. What's more advantageous is that it can be exposed to the outside when used as a indoor surface (that is, it can be used as a single piece). Since the three-silver itself has an extremely low emissivity and the addition of silver-free lowe, the two pieces of glass combined together have an extremely low K value, achieving excellent thermal insulation and heat preservation effects.

[0013] In summer, visible light enters the room through the film layer, and the double-layer functional layer shields the near-infrared and ultraviolet rays in the sunlight, achieving an excellent sunshade effect. People do not feel any burning sensation under the sunlight, greatly saving the indoor air conditioning costs. In winter, visible light enters through the double film layer into the room, and the long-wave heat energy emitted by indoor objects, walls, heating and human bodies is reflected back into the room by the double-layer Low-E film layer, effectively isolating the indoor heat from dissipating through the glass to the cold outdoors, greatly reducing heating costs.
