Suspended film hollow glass, manufacturing method, continuous production device and application

Abstract

The invention belongs to the technical field of hollow glass, and discloses suspended film hollow glass, a manufacturing method, a continuous production device and application. Spacer frames are bonded to corresponding peripheral positions of front glass and rear glass, the edge of the upper end of a suspended film is fixed between every two adjacent spacer frames in a bonding or welding or clamping manner, the lower end of each suspended film is fixedly connected with a bottom rod with the length matched with the width of the suspended film, and the bottom rods are fixed to the lower ends ofthe spacer frames. Cavities are formed between the suspended films and the front and rear glass and between the suspended films respectively. Spaces formed by the front glass, the rear glass and the outer sides of the spacer frames are fully covered with a structural adhesive, and the double-cavity or multi-cavity suspended film hollow glass is formed after solidification of the structural adhesive. The suspended film hollow glass can be conveniently manufactured by a simple process at a low cost and high productivity and has good heat insulation and sound insulation effects, the packaging width of the glass edge is equivalent to that of existing hollow glass, and the inherent breathing phenomenon of the hollow glass can be effectively relieved.

Description

technical field [0001] The invention belongs to the technical field of hollow glass, and in particular relates to a hanging film hollow glass, a manufacturing method, continuous production equipment and application. Background technique [0002] At present, with the development of green and energy-saving buildings, higher and higher requirements are put forward for the thermal insulation performance of the glass used. It has gradually developed from the original single-cavity insulating glass to three-glass two-cavity or even four-glass three-cavity insulating glass. . The increase of the hollow cavity brings the problem that the thickness and weight of the insulating glass are doubled, and the cost of the frame and hardware is also increased, so the cost of the door and window is also doubled; The technology of the intermediate glass of multi-cavity insulating glass has been gradually accepted by users and the market. Since the optical plastic film has the same optical pr...

AI Technical Summary

Problems solved by technology

[0008] The existing production process of suspended film insulating glass is to use elastic elements to fix and tension the suspended film. Mechanized and automated production cannot be realized, and the width of the frame is too wide, which brings about the problem of "cold edge", which not only affects the heat insulation effect, but also reduces the light transmittance of the glass; when the film is stretched, the frame only relies on butyl rubber Bonding, but the butyl glue is not cured, and the frame will creep under the tension of the suspension film, which will easily cause the surface tension of the suspension film to be uneven and the surface of the suspension film to be uneven, which will affect the qualified rate and production efficiency of the product
