Production process of two-glass three-cavity hot mirror film hollow glass

Abstract

The invention relates to a production process of two-glass three-cavity hot mirror film hollow glass. The production process of the two-glass three-cavity hot mirror film hollow glass has the beneficial effects that two layers of hot mirror films are arranged between two pieces of glass; the weight of the obtained hollow glass with three air layers is far smaller than that of the common four-glass three-cavity glass, so the energy saving problem can be solved to a greater extent and the wastage of the material (sheet glass) is also reduced to a great extent; the three air layers have the effect of improving the properties of the hollow glass to a greater extent; by designing customized auxiliary tools, namely positioning blocks and fixing rods, spacing bars are positioned accurately, are convenient to construct and are also not easy to misplace or incline; by forming balancing holes in the hot mirror films, the air pressures of hollow cavities at the two sides are consistent, thus eliminating the phenomena of unevenness in spreading, edge wrinkle, etc.

Description

technical field [0001] The invention relates to the preparation of an insulating glass, in particular to a production process of a two-glass three-cavity thermal mirror film insulating glass. Background technique [0002] At present, the most popular and market-recognized energy-saving glass in the market is Low-E insulating glass. However, as the construction market has higher and higher requirements for the thermal insulation performance of glass systems, glass has changed from single silver to double silver to Sanyin... Step by step, until today, the energy saving effect can only be improved by increasing the cavity. However, the thickness and weight of ordinary insulating glass will be greatly increased, and a series of new requirements for building structure and load will be put forward. How to achieve better thermal insulation effect without increasing the weight and obviously increasing the thickness, the thermal mirror film insulating glass provides an option for thi...

Problems solved by technology

[0004] Since the hot mirror film is a kind of soft polyester film, its hardness is equivalent to that of ordinary photographic film. Generally only two glasses and two cavities can be achieved

We all know that to realize two-glass three-cavity, there are two layers of hot mirror film in the middle, and the weight of the insulating glass with three air layers is far lighter than that of ordinary four-glass three-cavity glass, which can be more Solve the problem of energy saving, and also greatly reduce the loss of materials (original glass). These three air layers have improved the performance of the insulating glass to a greater extent, but the main technical difficulty lies in the placement of the spacer when assembling the sheets. , because of the three hollow cavities, it is necessary to place three layers of spacers. How to solve the problem that after the spacers are superimposed, they are not easy to tilt, and after the glass is placed, the spacers will not be subjected to external pressure; including the straightness of the spacer frame placement; The control of the depth of the secondary sealant and the avoidance of wrinkles in the film laying are the main problems in the lamination operation.
