The low-shading-coefficient single-silver low-radiation coated glass disclosed by the utility model has the characteristics of low radiation, low shading coefficient, and moderate light transmittance.
Description
Technical field
The utility model relates to a kind of coated glass, particularly relates to a kind of single silver low-radiation coated glass of the low shading coefficient that contains six tunic structures.
Background technology
Low radiation coated glass refers at Float Glass Surface deposition layer of metal silver as functional layer, near infrared ray in sunshine and the far infrared in living environment are played to reflex, thereby reduce glass to ultrared absorption and radiance, so be referred to as low radiation coated glass.Preparing low-emissivity coated hollow glass is the glass for building purposes of current generally acknowledged energy-saving effect the best.On market popular low radiation coated glass take pursue low heat transfer coefficient namely u (k) value be target, the in fact pursuit to heat transfer coefficient, has met the energy-conservation needs in high latitude area more fully., sunshine-duration abundant at the sunlight low latitudes of looking, shading coefficient Sc is definitely one and does not allow the factor of ignoring.
Low sunshade type Low-E glass, due to thermal insulation, the heat insulating ability of Low-E glass, makes it not be only applicable to southern area, is also applicable to northern area, summer it can effectively to stop that solar thermal energy enters indoor, and reflection is from outdoor far-infrared thermal radiation.Although winter, it limited entering of part solar thermal energy, it will stop more too and can heat energy enter indoorly in summer, and because the solar energy intensity in winter is only 1/3 left and right in summer, so its heat-insulating property is not affected yet.The multiple reflection colour that sunshade type Low-E glass has and moderate light transmittance, make it have abundanter decorative effect and outdoor sight line screening effect.This feature makes it obtain at home application more widely.
The low radiation coated glass shading coefficient of producing is now higher, cannot meet design requirement, and researches and develops low sunshade type low radiation coated glass, can meeting the market requirement, extend volume growth.
As can be seen here, above-mentioned existing low radiation coated glass, in structure and use, obviously still has inconvenience and defect, and is urgently further improved.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but have no for a long time applicable design always, by development, completed, and common product does not have appropriate structure to address the above problem, this is obviously the problem that the anxious wish of relevant dealer solves.Therefore how to found a kind of novel low radiation coated glass, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
Summary of the invention
The purpose of this utility model is, overcome the defect that existing low radiation coated glass exists, and provide a kind of low radiation coated glass that contains six tunic structures, the rete that wherein crome metal forms can effectively reduce shading coefficient, and this product has the advantages that radiance is low, shading coefficient is low, light transmittance is moderate.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.Single silver low-radiation coated glass according to the low shading coefficient the utility model proposes, it has glass substrate, at glass substrate surface, from bottom, is upwards disposed with the first tin oxide rete, the second tin oxide rete, chromium rete, silver film, nickel chromium triangle rete and silicon nitride film layer.
The purpose of this utility model and solve its technical problem and also can be applied to the following technical measures to achieve further.
Single silver low-radiation coated glass of aforesaid low shading coefficient, the thickness of wherein said the first tin oxide rete is 20-40 nanometer, the thickness of the second tin oxide rete is 20-40 nanometer, the thickness of chromium rete is 6-8 nanometer, the thickness of silver film is 9-12 nanometer, the thickness of nickel chromium triangle rete is 3-6 nanometer, and the thickness of silicon nitride film layer is 40-50 nanometer.
By technique scheme, the utility model at least has following advantages and beneficial effect: single silver low-radiation coated glass of low shading coefficient of the present utility model has the advantages that radiance is low, shading coefficient is low, light transmittance is moderate.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, and for above and other object of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

The specific embodiment
For further setting forth the utility model, be to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, its specific embodiment of single silver low-radiation coated glass, structure, feature and effect thereof to the low shading coefficient according to the utility model proposes, be described in detail as follows.
As shown in Figure 1, single silver low-radiation coated glass of low shading coefficient of the present utility model has glass substrate 1, on glass substrate 1 surface, from bottom, be upwards coated with successively the first tin oxide rete 2, the second tin oxide rete 3, chromium rete 4, silver film 5, nickel chromium triangle rete 6 and silicon nitride film layer 7, thereby form single silver low-radiation coated glass of six tunic structures.
In one embodiment, the utility model is under high vacuum environment, with magnetron sputtering coater, on Float Glass Surface, be coated with the method for six layers of nano material film, produce a kind of low radiation coated glass that low-E, low shading coefficient, natural daylight perspectivity are moderate, comprise a silver layer that has.
In one embodiment, on low sunshade type list silver low-radiation coated glass Shi described in the utility model factory coating machine, complete as follows: first coating chamber is evacuated to base vacuum degree 5 * 10
- 4below Pa, be filled with process gas (argon gas, nitrogen, oxygen), make the interior process gas pressure stability of coating chamber 2.5 * 10
