Technical Field

The invention belongs to the technical field of hollow glass, and particularly relates to suspended membrane hollow glass, a manufacturing method, continuous production equipment and application.

Background

At present, 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 original single-cavity hollow glass is gradually developed into three-glass two-cavity hollow glass 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 that the glass cannot replace, the hollow glass of the suspended membrane has 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). However, the processing technology is too complex, and the difficulty in laminating and packaging the glass is high, so that the production efficiency is not high, the quality is not stable, and the like.

The structural characteristics of the existing suspension membrane hollow glass determine that the structure is too complex, the production process is complicated, and the manufacturing and processing difficulty is large. Therefore, since the commercial production of the hollow glass with suspended membrane, the insertion of the elastic element, the fixing and tensioning of the optical plastic film and the encapsulation of the inner and outer sheets of glass become technical bottlenecks that restrict the automatic continuous production. Meanwhile, in order to ensure that the film suspension has pretension, the film surface is smooth, the stability of the spacing frame and the requirements on the bonding strength and the sealing property of the glass are met, the packaging width of the film suspension at the edge of the glass is too wide, and the problem of cold edge is caused, so that the heat insulation effect is influenced. Thus, although the hollow glass with suspended membrane has a promising prospect, it has not been widely used due to its high cost, low productivity, high price, and long supply time.

Through the above analysis, the problems and defects of the prior art are as follows: the structural characteristics of the existing suspension membrane hollow glass determine that the structure is too complex, the production process is complicated, and the manufacturing and processing difficulty is large.

The difficulty in solving the above problems and defects is:

firstly, how to utilize simple structure will hang the membrane fixed with tighten, secondly how to fix the interval frame fast, prevent that the interval frame from moving at the membrane in-process that tightens to cause and hang the membrane and produce the fold, thirdly, how to improve product structure and production technology and realize mechanized, serialization production.

The significance of solving the problems and the defects is as follows:

the existing production process of the hollow glass with the suspended membrane adopts an elastic element to fix and tension the suspended membrane, the installation of the elastic element and the suspended membrane needs a complex frame structure, and the tensioning of the suspended membrane needs manual adjustment of a tensioning bolt, so that the mechanical and automatic production cannot be realized, the frame width is too wide, the cold edge problem is caused, the heat insulation effect is influenced, and the light transmittance of the glass is reduced; when the membrane is stretched, the frame is only adhered by butyl rubber, and the butyl rubber is not solidified, and the frame can creep under the action of the tension force of the suspended membrane, so that the unbalanced surface tension of the suspended membrane and the uneven surface of the suspended membrane are easily caused, and the qualification rate and the production efficiency of products are influenced. The significance of solving the problems and the defects is as follows: if a new product structure and a new production process are adopted, the assembly time and the membrane stretching period are shortened, the energy consumption can be greatly reduced, and the continuous and automatic production can be realized, so that the production efficiency can be greatly improved, the production cost is reduced, the productivity is increased, the performance is improved, the market price and the supply time are further reduced, and the suspended membrane hollow glass and related products are popularized and applied in a large range.
