The coated insulating glass is surely an insulating glass composed associated with one coated glass and one piece of other a glass. In order to safeguard the film from atmospheric erosion and raise the service life, the painted surface should face back to the inside.

Coated insulating glass is normally used for glass curtain walls of buildings. Being an architectural ornament, it brings a beautiful, generous and bright image to the building, enhancing the beauty belonging to the building. However, in true use, we often find that some buildings using covered insulating glass show photograph scattering. Make the beauty of the building disappear and even use a negative impact. The author conducted an in depth study on this matter, and conducted a various investigations and experiments to check on relevant data at property and abroad, and obtained data for analysis.
The basic principle of scattering belonging to the coated insulated glass factory image could be that the glass cannot form an integral plane to the curtain wall or your regional part is not a plane, but is bent, which causes the image to scatter, even proper mirror shape. The reasons why you are this phenomenon are intricate and multifaceted:

First, the causes for design and set up:

With the rise in addition to increase of high-rise houses, people's requirements for your aesthetic appearance of homes have increased, and the exact use of glass panels has grown larger and larger. The wind pressure load within the glass itself also boosts. There are two varieties of wind pressure loads within the glass: internal wind strain and external wind pressure load. When the external wind pressure on the insulating glass is a lot more than the internal wind stress, the glass surface is actually curved inward, and the surface of the glass is concavely bent; and when the internal wind pressure is higher than the external wind strain, the surface of the glass is outwardly curved to get convex; only when inside and outside When the compressive loads are equal or close, the glass can form a planes. Therefore, in the design and installation, the wind pressure load from the glass should be totally considered. This wind load isn't just the external wind pressure load for the glass itself, but also the combined the wind pressure weight inside and outside the particular hollow glass.

The change of place inside and outside your insulating glass varies using the change of the ambient temperature as well as the installation area. The difference in stress between the regions is very large, especially in this plains and plateaus. Once the products produced in the plain area are employed in the plateau place, the inside of the particular insulating glass is positively pressed and also the glass is drummed facing outward. On the contrary, it becomes a poor pressure and the magnifying glaas is concave inward. Hence, when designing the insulating glass to get installed in different regions, the structure and specifications with the insulating glass product must be designed according to different regions and the highest wind pressure. The influence of the change of the ambient temperature for the load change of the insulating glass is mainly manifested by the change belonging to the volume of the dry air sealed inside hollow glass with the change of the temperature, thereby causing the actual internal load to alter, and the glass area is bent inward and also outward. After repeated experiments by HotTag, for 550mmx1100mm (5+9+5) mm square coated insulating glass, the displacement of the center of the single-sided glass floor changes about 0. 03mm for every 1 °C change inside ambient temperature. It sometimes appears that the change in temperature carries a considerable influence on the flatness in the insulating glass.

Insulating tumbler has unique installation and construction conditions. During the construction from the glass curtain wall, in the matter of construction within the setting up and construction specifications, when the glass is sealed, the thickness with the peripheral sealant is gi, and the metal mode plus itself has deflection as well as joint connection, so that the glass cannot be inside same plane or even though the whole In the very same plane, there is your local variation, which can also cause image scattering.
2nd, the reason for the processing of glass, creation methods

As we just about all know, most of the insulating glass produced within China is vertical laminated and also horizontally sealed. During the splicing process, the glass itself is just not affected by the force and would not deform. However, when the glue is sealed, the upper glass is bent by its own gravity, and the reduced glass is bent further up, and the air that will presses the inner area overflows outward. Although it is only a trace total, after the sealant, a slight negative pressure is generated in the insulating glass. The a couple pieces of glass will probably bend inward. Especially if the two pieces of glass are thin, the product specifications are definitely obvious. When the ambient temperature is lowered as well as external air pressure is definitely increased, the curvature belonging to the glass is also increased until the two pieces of glass tend to be bonded together, and the energy saving effect of the insulating glass is lost.

Third, the inevitable trigger

In order to ensure the airtightness on the window during installation, it really is generally necessary to seal the glass as well as metal frame with the sealant. However, as the temperature changes, the coefficient of development between the glass as well as frame is different. Tensile or compressive stress is generated surrounding the glass. Although there is often a sealant as a barrier, this stress cannot possibly be completely eliminated. If this ambient temperature changes, the stress is likewise increased. As a result from the stress, the deformation on the edge of the cup is increased, and also the glass is shattered. This situation is frequently found on monolithic a glass.

In the actual manufacturing process, the selection on the original glass piece features a great influence on the bending resistance in the glass. Generally, in tempered a glass, heat-strengthened glass and regular glass, from the factor of wind pressure level of resistance, tempered glass is the largest, and heat enhancement can be second. These two a pair of glasses are better to resist external stress than ordinary glass. Therefore, we recommend to utilize tempered coating or heat-enhanced coated glass because original film when generating coated insulating glass; the product variety ought to use inflatable glass as much as possible, and it is suitable to scale back the specification of a glass and reduce the glass deformation due to various reasons.
