Three advantages for the scattering of magnifying glaas curtain wall in insulation glass

The coated insulating glass can be an insulating glass composed with one coated glass and one piece of other tumbler. In order to shield the film from atmospheric erosion and raise the service life, the sprayed surface should face inward.

Coated insulating glass is mostly used for glass drape walls of buildings. As a possible architectural ornament, it brings an incredible, generous and bright image into the building, enhancing the beauty with the building. However, in true use, we often realize that some buildings using coated insulating glass show impression scattering. Make the beauty of the building disappear and even employ a negative impact. The author conducted a close study on this concern, and conducted a selection of investigations and experiments to check on relevant data at house and abroad, and obtained data for analysis.
The basic principle of scattering on the coated tempered glass for sale image is always that the glass cannot form an integral plane around the curtain wall or the area part is not any plane, but is curved, which causes the photo to scatter, even right into a mirror shape. The reasons for this phenomenon are difficult and multifaceted:

First, the issues for design and installment:

With the rise in addition to increase of high-rise complexes, people's requirements for this aesthetic appearance of complexes have increased, and the very use of glass panels is now larger and larger. The wind pressure load within the glass itself also boosts. There are two types of wind pressure loads to the glass: internal wind stress and external wind force load. When the external wind pressure of the insulating glass is above the internal wind strain, the glass surface is usually curved inward, and the surface from the glass is concavely bent; and when the bodily wind pressure is higher than the external wind strain, the surface of the glass is outwardly curved to be convex; only when inside and outside When the compressive loads are identical or close, the a glass can form a aircraft. Therefore, in the style and installation, the wind pressure load in the glass should be entirely considered. This wind load is not only the external wind pressure load within the glass itself, but also the mixture of the wind pressure weight inside and outside this hollow glass.

The change of heap inside and outside the particular insulating glass varies considering the change of the ambient temperature and the installation area. The difference in strain between the regions is quite large, especially in this plains and plateaus. When the products produced in the plain area are utilized in the plateau community, the inside of the particular insulating glass is positively pressed as well as the glass is drummed outward. On the contrary, it becomes a negative pressure and the cup is concave inward. For that reason, when designing the insulating glass that they are installed in different locations, the structure and specifications on the insulating glass product ought to be designed according to the several regions and the highest possible wind pressure. The influence belonging to the change of the ambient temperature within the load change of the insulating glass is mainly manifested by the change from the volume of the dry air sealed included in the hollow glass with the change with the temperature, thereby causing this internal load to switch, and the glass area is bent inward in addition to outward. After repeated experiments by HotTag, pertaining to 550mmx1100mm (5+9+5) mm square coated insulating glass, the displacement of the biggest market of the single-sided glass area changes about 0. 03mm for every 1 °C change with ambient temperature. It sometimes appears that the change in temperature features a considerable influence on the flatness from the insulating glass.

Insulating cup has unique installation plus construction conditions. During the construction with the glass curtain wall, regarding construction within the assembly and construction specifications, once the glass is sealed, the thickness belonging to the peripheral sealant is uniform, and the metal shape plus itself has deflection and also joint connection, so the glass cannot be while in the same plane or although the whole In the same plane, there is any local variation, which can also cause image scattering.
Minute, the reason for your processing of glass, development methods

As we all know, most of the insulating glass produced in China is vertical laminated and horizontally sealed. During the particular splicing process, the glass itself is just not affected by the force and won't deform. However, when that glue is sealed, top of the glass is bent by a gravity, and the lower glass is bent up, and the air that presses the inner space overflows outward. Although it truly is only a trace total, after the sealant, a slight negative pressure is generated in the insulating glass. The a pair of pieces of glass could bend inward. Especially when the two pieces of tumbler are thin, the product specifications become more obvious. When the ambient temperature is lowered plus the external air pressure is actually increased, the curvature of the glass is also increased until the two pieces of glass usually are bonded together, and the energy saving effect in the insulating glass is shed.

Third, the inevitable bring about

In order to ensure the airtightness of the window during installation, it's generally necessary to seal the glass and the metal frame with your sealant. However, as the temperature changes, the coefficient of development between the glass and the frame is different. Tensile or compressive stress is generated across the glass. Although there is a sealant as a stream, this stress cannot become completely eliminated. If that ambient temperature changes, the stress is likewise increased. As a result belonging to the stress, the deformation on the edge of the magnifying glaas is increased, and possibly the glass is broken. This situation is frequently found on monolithic tumbler.

In the actual generation process, the selection belonging to the original glass piece is known for a great influence on the bending resistance on the glass. Generally, in tempered goblet, heat-strengthened glass and everyday glass, from the aspect of wind pressure level of resistance, tempered glass is the largest, and heat enhancement is actually second. These two eyeglasses are better to resist external stress than ordinary glass. Therefore, we recommend to apply tempered coating or heat-enhanced coated glass as the original film when generating coated insulating glass; the product variety need to use inflatable glass whenever you can, and it is suitable to lessen the specification of glass and reduce the glass deformation brought on by various reasons.
