Hollow glass was invented by the Americans in 1865. It is a new type of building material with good heat insulation, sound insulation, aesthetic application, and can reduce the weight of the building. It uses two (or three) glass and uses high strength and high strength. Air-tight composite adhesive, the glass sheet and the aluminum alloy frame containing the desiccant are bonded to form a high-performance sound-insulating and heat-insulating glass. The main materials thereof are a glass, an aluminum spacer, an angle bolt, and a butyl rubber. , polysulfide rubber, desiccant. Hollow glass has a variety of properties superior to ordinary double-glazed glass and has therefore been recognized by various countries in the world.
Insulating glass is a new type of building material with good thermal insulation, aesthetic application, and can reduce the weight of the building. If environmental protection, heat insulation, sound insulation, and beautiful materials are used in home decoration, they can certainly play a different role. effect.
Hollow glass can be selected according to the requirements of a variety of different properties of the original glass, such as colorless transparent float glass embossed glass, heat-absorbing glass, heat reflective glass, wire glass, tempered glass and frame (aluminum frame or glass, etc. ), made by cementing, welding or welding.
Hollow glass has the following characteristics:
First, there is a larger energy-saving effect, high-performance hollow glass, due to a special layer of metal film, can achieve 0. 22-0. 49 shielding factor, so that indoor air conditioning cooling load, heat transfer coefficient better than ordinary insulating glass, To reduce the indoor air conditioning load can play a great efficiency. Therefore, the larger the window is opened, the more obvious the energy saving effect.
The second is to improve the indoor environment. High-performance hollow glass can intercept the heat emitted by the sun to the room, thereby preventing the discomfort caused by radiant heat and reducing the dizziness caused by sunlight.
The third is rich in color and artistic, high-performance insulating glass has a variety of colors, you can use colors as needed to achieve a more ideal artistic effect.
Fourth, the use of high-performance hollow glass is applicable to public buildings such as office buildings, exhibition rooms, and libraries, and special buildings such as computer rooms, precision instrument workshops, and chemical factories that require constant temperature and humidity. It can also be used for sun protection and anti-glare areas.
The use of hollow glass should be noted that due to the dry air sealed in the hollow glass, the internal air pressure will change according to the change of temperature and air pressure, but only a small deformation will occur on the glass surface. In addition, slight warpage may occur during manufacture, and distortion may also occur during construction. Therefore, due to the presence of such factors, sometimes the light reflection of the insulating glass will also change accordingly, and attention should be paid to it. With different colors, reflections are not the same.
