ag is used as the silver layers I and II, and the thickness of the film layer is 5-15 nm;

the protective layers I, II, III and IV are NiCr, and the thickness of the film layer is 1-5 nm.

Each film layer is a film layer prepared by adopting a vacuum magnetron sputtering coating process.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

the utility model discloses a two silver low emissivity coated glass of face neutral colour, this two silver low emissivity coated glass pass through each level structure setting, through the transmission of dielectric layer and silver layer, make face colour have more neutral effect, go into many two-layer metal protection layers, make the rete more firm. The surface of the steel double-silver coated glass film is close to the external reverse color, and no visual deviation is generated.
