With the development of green energy-saving buildings, higher and higher requirements are put forward on the heat insulation performance of the used glass, and the glass is gradually developed from the original single-cavity hollow glass to three-glass two-cavity or even four-glass three-cavity hollow glass. The increase of the hollow cavity brings about the problems that the thickness and the weight of the hollow glass are increased by times, the cost of frame materials and hardware is increased, and the cost of doors and windows is also increased by times; and the technology of replacing the middle glass of the double-cavity or multi-cavity hollow glass by the optical plastic film is gradually accepted by users and markets. Since the optical plastic film has the same optical characteristics as the ultra-thin glass, and has the flexibility characteristics and ultraviolet and infrared ray blocking properties that the glass cannot replace, the hollow suspension film glass has a huge market application space.
A processing technique of suspending an optical plastic film in a cavity composed of two glass sheets and applying a certain pre-tension to the optical plastic film by an elastic member has been commercially produced (see patent application nos. 2013104899426, 2013104899939, 2013104901017, 2015104784099, and 2017101860437).
