The hollow glass is formed by uniformly separating two or more pieces of glass by effective support and bonding and sealing the periphery, so that a cavity of dry gas is formed between glass layers, and a gas layer with certain thickness and limited flow is formed inside the cavity.

The present invention is further described with reference to specific embodiments, however, it will be understood by those skilled in the art that the detailed description given herein with respect to the drawings is for better explanation and that the present invention is necessarily to be construed as limited to those embodiments, and equivalents or common means thereof will not be described in detail but will fall within the scope of the present application.
Example 1
As shown in fig. 1: outer glass 1 and interior glass 3 are parallel and the interval sets up, are provided with space bar 5 between outer glass 1 and the interior glass 3, and in this embodiment, space bar 5 is the aluminium space bar, and 5 intervals of space bar are provided with many. The spacing bar 5 is densely distributed with a plurality of micropores to form a plurality of channels.
The outer glass coating layer 2 of the outer glass 1 is arranged between the outer glass 1 and the inner glass 3, and the outer glass coating layer 2 of the outer glass 1 is connected with the corresponding side of the outer glass 1. The outer glass 1 is an off-line low-e glass.
The off-line low-e glass is prepared by leaving a float glass production line, and uniformly plating metallic silver and other metals and metal compounds with extremely low emissivity on the surface of the glass by a vacuum magnetron sputtering method according to a certain sequence. Therefore, the outer glass film coating layer 2 is soft and is easy to damage due to collision, and in addition, the material of the outer glass film coating layer 2 is metal silver and other metals and metal compounds, so that the outer glass film coating layer 2 is easy to oxidize to reduce the light transmission and energy-saving performance of the glass, and therefore, the outer glass film coating layer 2 can only be arranged between the inner glass 3 and the outer glass 1 for protection.
The inner glass coating layer 4 of the inner glass 3 is arranged on one side of the inner glass 3 facing the indoor, the inner glass coating layer 4 is a fluorine-doped tin oxide film, and the inner glass coating layer 4 is connected with the corresponding side of the inner glass 3. The inner glass 3 is an on-line low-e glass.
In the production process of float glass, chemical solution with tin salt as main component is sprayed onto the surface of hot glass, and the glass is heated to react on the surface of the glass to form low-radiation fluorine-doped tin oxide film, which is combined with the glass and integrated with the glass, so that the inner glass film layer 4 connected to the inner glass 3 has high hardness and is not damaged by collision.
Example 2
The inner glass 3 is still on-line low-e glass, the inner glass coating layer 4 of the inner glass 3 is arranged on the side of the inner glass 3 facing the indoor, the inner glass coating layer 4 is a fluorine-doped tin oxide film, the outer glass 1 is on-line low-e glass, and the outer glass coating layer 2 of the outer glass 1 is arranged between the outer glass 1 and the inner glass 3 and is connected with the corresponding side of the outer glass 1.
Compared with the traditional hollow glass, the energy-saving hollow glass composite structure has the following heat preservation and insulation parameters as shown in the following table:
in the table, experiment 1 is example 1, i.e. the inner glass 3 is on-line low-e glass, the outer glass 1 is off-line low-e glass, the inner glass coating layer 4 faces the indoor side, and the outer glass coating layer 2 is located between the inner glass 3 and the outer glass 1 and connected with the corresponding side of the outer glass 1; experiment 2 is a control group of example 1, i.e. the inner glass 3 is on-line low-e glass, the outer glass 1 is off-line low-e glass, and the inner glass coating layer 4 and the outer glass coating layer 2 are both positioned between the inner glass 3 and the outer glass 1 and are respectively connected with the corresponding sides of the inner glass 3 and the outer glass 1; experiment 3 is example 2, i.e. both the inner glass 3 and the outer glass 1 are on-line low-e glasses, the inner glass coating layer 4 faces the indoor side, and the outer glass coating layer 2 is located between the inner glass 3 and the outer glass 1 and connected with the corresponding side of the outer glass 1; experiment 4 is a control of example 2, i.e. both the inner glass 3 and the outer glass 1 are on-line low-e glasses, and both the inner glass coating 4 and the outer glass coating 2 are located between the inner glass 3 and the outer glass 1 and connected to the corresponding sides of the inner glass 3 and the outer glass 1, respectively.
Comparing experiment 1 and experiment 2, it can be seen that: no matter in winter or summer under the prerequisite that does not influence visible light transmissivity, experiment 1's heat transfer coefficient (U value) will be less than experiment 2's U value, and it is better to show experiment 1's heat preservation thermal-insulated effect, compares with experiment 2, and the heat of outside is difficult for getting into indoorly, and indoor temperature receives outdoor temperature's influence less. The above points are confirmed by the SC (solar shading coefficient) of experiment 1 being smaller than that of experiment 2 and the SHGC (solar heat gain coefficient) of experiment 1 being smaller than that of experiment 2. Therefore, the heat insulating and heat insulating effect of the glass structure of experiment 1 is superior to that of the glass structure of experiment 2.
Comparing experiment 3 and experiment 4, it can be seen that: on the premise of not influencing the visible light transmittance, no matter in winter or summer, the heat transfer coefficient (U value) of experiment 3 is less than the U value of experiment 4, which shows that the heat preservation and insulation effect of experiment 3 is better, compared with experiment 4, the heat outside is not easy to enter the room, and the indoor temperature is less influenced by the outdoor temperature. The results of experiment 3, in which SC (solar shading coefficient) was smaller than that of experiment 4 and experiment 3, in which SHGC (solar heat gain coefficient) was smaller than that of experiment 4, collectively demonstrate the above viewpoints. Therefore, the heat insulating and heat insulating effect of the glass structure of experiment 3 is superior to that of the glass structure of experiment 4.
From the above, the inner glass coating layer 4 is arranged on one side of the inner glass 3 facing the indoor, so that the heat preservation effect and the heat insulation effect are improved on the premise of not influencing the visible light transmittance, and the use effect is good.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical substance of the present invention still belong to the protection scope of the technical solution of the present invention.
