Why does the hollow glass crack after closing the piece?

With the emphasis on energy saving in Chinese construction, hollow glass hollow laminated glass is more and more common as an energy saving product on building doors and Windows. Due to the low technical threshold of insulating glass production and broad market prospects, the number of insulating glass production enterprises has been increasing in recent years, and most of them are enterprises with relatively small scale and relatively low technical management level.

The lack of equipment in small enterprises is often easy to lead to unstable product quality, among which the problems often encountered in the production of insulating glass are cracks after closing the piece.

At this time, the production enterprise should check whether there is a problem with the hollow plate press at the first time, and see whether the crux is here.

First, check whether the pressure of the plate press is uniform. This can be confirmed by observing whether the pressing of butyl glue is uniform and consistent, and whether there is sometimes whitening phenomenon.

Second, check the inner wall of the plate press to see if there is any impurities, and clean it up if found.

Third, check the high-density plate or stainless steel plate of the plate press to see if the surface is flat, because the long-term use of the plate press panel will appear deformation and uneven condition, which will also lead to cracks after the hollow glass is closed.

Insulating glass is regarded as a kind of product with high safety in the curtain wall glass of high-rise buildings and is chosen by people. But once the product cracks, it will not only become unsafe, but also buried a major hidden danger to the safety. Therefore, the production enterprises should strictly check the quality, and the consumers should also try to see whether the glass has cracks when buying.
