Background technique

In order to make people's living environment more comfortable and healthy, and at the same time adapt to the sustainable development of the world, make full use of effective energy, low-radiation energy-saving glass with low visible light reflectivity and no reflected light pollution is gradually being recognized and used by people. Energy-saving glass has a high reflectivity for far infrared rays, which can achieve good thermal insulation performance; high visible light transmittance can maintain a good indoor lighting effect.

As we all know, the heat energy in nature is mainly the direct heat of the sun and the radiant heat of surrounding objects. Among them, 98% of the energy of the direct solar heat is distributed in the light region with a wavelength of 0.3 to 3 μm. In addition, there is a large amount of far-infrared thermal radiation energy, and its energy is distributed in the light region with a wavelength of 3-40 μm. Outdoors, far-infrared radiant energy is radiated by the sun irradiated on the object and then absorbed by the object, which is one of the main heat sources from outdoors in summer; indoors, far-infrared thermal radiant energy is generated by heating and sunlight. Furniture and objects such as the human body are the main energy sources in the interior. Low-emissivity energy-saving glass can transmit outdoor solar energy and visible light like ordinary float glass, and can also reflect the radiant heat of objects back like an infrared reflector, so as to achieve the purpose of energy saving.

The energy-saving glass in the prior art mainly uses the silver layer as the functional layer, which is divided according to the number of silver layers, and is mainly divided into single-silver energy-saving glass, double-silver energy-saving glass and triple-silver energy-saving glass. Among them, triple-silver energy-saving glass is difficult to process, but its energy-saving effect is obviously stronger than that of single-silver energy-saving glass and double-silver energy-saving glass. However, the common triple-silver energy-saving glass cannot be used after tempering, resulting in the arc part in some buildings cannot be used. , to a certain extent, restricts the use of Sanyin energy-saving glass products. In addition, the non-temperable double-silver energy-saving glass can only be cut and ground before coating. Due to the different sizes of different engineering products, it is impossible to maximize the loading rate of coating equipment during production, resulting in high equipment energy consumption. ; Furthermore, the non-temperable double-silver products can only be transported to the installation site after the original factory lamination is completed, and the transportation cost is high.

In addition, energy-saving glass has a wide range of applications, and different applications have different requirements for colors. However, the common three-silver energy-saving glass is mostly blue and green, which cannot meet the market demand for gray series three-silver low-amplitude energy-saving glass. need.
