Problems solved by technology

[0003] In the process of traditional low-emissivity glass processing, in order to achieve a better U value and selectivity coefficient Lsg, it is necessary to increase the thickness of the silver layer in the film layer to reduce the emissivity of the glass film layer to obtain an ideal selectivity coefficient, but Increasing the thickness of the silver layer means that the transmittance of visible light decreases, and the appearance color presents an interference color, which affects the use of glass

Description

【Technical field】 [0001] The invention relates to the field of special glass, in particular to a silver-containing low-emissivity glass and a manufacturing method thereof. 【Background technique】 [0002] Low-emissivity glass is a layer of infrared reflective material deposited on the surface of the glass, so that the visible light in the sunlight can pass through, and like an infrared reflector, it excludes the infrared rays in the sunlight and reflects the secondary radiant heat of the object back. special glass. Through the use of low-e glass, the effects of controlling sunlight, saving energy, controlling heat and improving the environment can be achieved. [0003] In the process of traditional low-emissivity glass processing, in order to achieve a better U value and selectivity coefficient Lsg, it is necessary to increase the thickness of the silver layer in the film layer to reduce the emissivity of the glass film layer to obtain an ideal selectivity coefficient, but ...
