Efficient and energy-saving hollow film glass

Abstract

The invention discloses efficient and energy-saving hollow film glass. A plastic film bag with the sealed periphery is placed in sealed space formed by two pieces of glass, a tensioning frame is arranged in the plastic film bag, the sealed space is formed by the two pieces of glass and a structure frame sealed between the two pieces of glass, the plastic film bag is fixed in the structure frame in a suspension manner, so that an internal hollow thermal insulating layer consisting of two plastic films is formed, two external hollow thermal insulating layers are formed among the plastic film bag and the two pieces of glass, and the internal hollow thermal insulating layer and the external hollow thermal insulating layers are communicated with each other through ventilating tube nozzles and are communicated with the outside through breather valves and breather tubes according to a ventilating sequence. The efficient and energy-saving hollow film glass has a low U value, optical functions of the films and the glass are set flexibly, and a sealing effect is reliable. Besides, a production and processing process can be simplified, and manufacturing cost is optimized.

Description

technical field [0001] The invention relates to the field of green building energy saving, in particular to a high-efficiency and energy-saving glass with a hollow film layer for glass doors, windows and curtain wall systems. Background technique [0002] According to the research results of the Lawrence Berkeley National Laboratory in the United States, it is shown that zero-emission buildings require the U value of the heat transfer coefficient of the energy-saving glass window system to be below 0.57W / m2-K (0.10Btu / h-ft2-℉). For this reason, multiple insulation layers are usually used and filled with inert gas, and one of the hollow insulation layers needs to be realized with a low-emissivity coating (Low-e). [0003] As we all know, many patented technologies are based on the above principles to realize the invention of more efficient and powerful energy-saving glass. In the airtight space formed by two pieces of glass, a non-structural intermediate layer is built, such...

Problems solved by technology

[0005] 2. The impact of the added intermediate layer on the overall weight and size (thickness) of the glass unit can be controlled to a minimum. If the weight increases, it means that the construction installation cost increases. If the size, especially the thickness, also means that the doors and windows And the need to change the curtain wall structure brings about the increase in the cost of design and processing

[0006] 3. The added intermediate layer should provide a more reliable sealing structure for the overall sealing of the glass unit. Usually, the installation of the intermediate layer will increase the difficulty of sealing and the negative factors that the sealing effect is difficult to guarantee.

[0007] 4. The added intermediate layer will increase the complexity of the overall manufacturing process of the glass unit, and the complexity of the manufacturing process will increase the difficulty of product quality control

[0008] 5. The added intermediate layer will increase the overall manufacturing cost of the glass unit, such as the structure and material of the intermediate layer will increase the cost of components and construction materials

Although there are fundamental improvements in the overall function, especially in terms of reducing U value and weight, there are still problems that need to be improved in terms of sealing requirements, processing technology difficulty and manufacturing cost
