The coated insulating glass is usually an insulating glass composed with one coated glass then one piece of other glass. In order to guard the film from atmospheric erosion and improve the service life, the coated surface should face inward.

Coated insulating glass is mostly used for glass drape walls of buildings. Being a architectural ornament, it brings an attractive, generous and bright image into the building, enhancing the beauty with the building. However, in exact use, we often know that some buildings using covered insulating glass show impression scattering. Make the beauty in the building disappear and even use a negative impact. The author conducted an in depth study on this matter, and conducted a variety of investigations and experiments to measure relevant data at home and abroad, and amassed data for analysis.
The basic principle of scattering in the coated hollow glass image could be that the tempered Laminated Glass cannot form an integral plane on the curtain wall or the area part is not any plane, but is curved, which causes the photograph to scatter, even right mirror shape. The reasons why you are this phenomenon are intricate and multifaceted:

First, why they broke up for design and installing:

With the rise and increase of high-rise homes, people’s requirements for the particular aesthetic appearance of houses have increased, and the actual use of glass panels happens to be larger and larger. The wind pressure load within the glass itself also raises. There are two types of wind pressure loads about the glass: internal wind pressure and external wind stress load. When the external wind pressure on the insulating glass is greater than the internal wind pressure, the glass surface is usually curved inward, and the surface on the glass is concavely curved; and when the central wind pressure is above the external wind strain, the surface of the particular glass is outwardly curved to become convex; only when inside and outside Should the compressive loads are identical or close, the goblet can form a aeroplanes. Therefore, in the design and installation, the wind pressure load in the glass should be totally considered. This wind load isn’t just the external wind pressure load around the glass itself, but also the combination of the wind pressure heap inside and outside the hollow glass.

The change of fill inside and outside the actual insulating glass varies when using the change of the ambient temperature along with the installation area. The difference in demand between the regions is extremely large, especially in the actual plains and plateaus. If the products produced in the plain area are employed in the plateau region, the inside of the insulating glass is positively pressed as well as the glass is drummed facing outward. On the contrary, it becomes a negative pressure and the a glass is concave inward. As a result, when designing the insulating glass to be installed in different regions, the structure and specifications of the insulating glass product needs to be designed according to the several regions and the greatest wind pressure. The influence from the change of the ambient temperature about the load change of the insulating glass is especially manifested by the change belonging to the volume of the dry air sealed included in the hollow glass with the change with the temperature, thereby causing the internal load to adjust, and the glass area is bent inward as well as outward. After repeated experiments by HotTag, regarding 550mmx1100mm (5+9+5) mm square coated insulating glass, the displacement of the center of the single-sided glass surface changes about 0. 03mm for every 1 °C change with ambient temperature. It is so visible that the change in temperature has a considerable influence on the flatness on the insulating glass.

Insulating a glass has unique installation as well as construction conditions. During the construction of the glass curtain wall, individual construction within the assembly and construction specifications, once the glass is sealed, the thickness from the peripheral sealant is gi, and the metal shape plus itself has deflection or joint connection, so which the glass cannot be within the same plane or but the whole In the exact same plane, there is your local variation, which can cause image scattering.
Following, the reason for this processing of glass, creation methods

As we almost all know, most of the actual insulating glass produced with China is vertical laminated as well as horizontally sealed. During the splicing process, the glass itself isn’t affected by the force and won’t deform. However, when that glue is sealed, the upper glass is bent by a gravity, and the decrease glass is bent up, and the air which presses the inner living space overflows outward. Although its only a trace amount, after the sealant, a slight negative pressure is generated inside insulating glass. The a couple of pieces of glass can bend inward. Esp
