New technology for building glass film and energy-saving building materials

New technology of energy-saving building materials for building glass film. In building energy-saving, building glass doors and windows are a very weak and important link that is often overlooked. However, it is also an area with great potential to be tapped in building energy-saving work. At present, many old buildings in our country use a large number of steel windows and aluminum windows equipped with ordinary transparent glass. Even in new buildings in recent years, especially the doors and windows of residential buildings, ordinary transparent glass is still widely used.
In the long summer in the south, there is abundant sunshine and the temperature is often above ℃. During the day, most of the outdoor solar heat radiation enters the room through glass doors and windows, causing the room temperature to rise. It is necessary to increase the cooling load to offset the heat. Most of the indoor cooling energy at night is lost through glass doors and windows, which greatly increases energy consumption. This is the direct reason for the high energy consumption of buildings. One of the effective solutions is to use new energy-saving glass doors and windows to minimize the transmittance of solar radiation.
People may have noticed that the glass used in doors and windows of buildings in our country is undergoing a development process from ordinary white glass to darker heat-absorbing glass (commonly known as brown glass) to light green heat-absorbing glass and coated glass to light green insulating glass. . Because light green glass is cheap and has a certain thermal insulation effect, it is being widely used in doors and windows of ordinary residential buildings. Insulated glass is gradually being used in the doors and windows of newly built high-end luxury homes because of its good sound insulation and heat insulation properties. However, Its high price also restricts popularization and promotion. Moreover, the above-mentioned types of glass all have the most fatal weakness of ordinary glass, which is that it is brittle and fragile, that is, the safety performance of the glass is low.
How can buildings adopt effective, economical and convenient methods to solve the problem of heat insulation and energy saving of building glass doors and windows and improve their safety performance?
Multifunctional glass film is a high-tech energy-saving product that can effectively control solar thermal radiation and increase the strength of glass. It is a new type of energy-saving building material.
This kind of film is made of a special polyester film as the base material. The middle of the polyester film is coated with various high-reflectivity metal or metal oxide coatings using magnetron sputtering and other methods. A functional glass film that is both light-transmitting and highly heat-insulating, made of composite lamination using a special process. It can transform cheap ordinary transparent flat glass into safety insulating glass with multiple colors and functions.
For example, a film can be directly attached to ordinary transparent glass to resemble coated glass to form safety insulating glass with multiple colors and functions. For example, a film can be directly attached to ordinary transparent glass to turn it into insulating glass like film glass, and ordinary transparent glass can be turned into safety insulating glass with both heat insulation and safety and explosion-proof functions. A colored or colorless transparent safety film can also be added to the curtain wall glass to make the coating layer of the coated glass less likely to oxidize, fade and fall off, and increase its ability to resist wind pressure and acid and alkali erosion. According to tests, ordinary glass with two layers of safety bulletproof film can prevent the shooting of micro submachine guns without penetrating and without splashing objects, which shows its reliable impact resistance. Safety glass made of ordinary glass with a safety film has reliable safety performance, is low-priced and can significantly reduce the weight of the glass. Explosion-proof glass is made by pasting a special safety film on ordinary glass of a certain thickness. In the event of an explosion, it can effectively withstand direct damage from the explosion and damage caused by flying glass fragments. It can also reduce the risk of damage to the bombed facilities and facilities near the explosion center. Repair costs.
