Hollow glass invented by americans in 1865, is a kind of good heat insulation, sound insulation, beautiful and applicable, and can reduce the building self-respect of new building materials.
It is to use two pieces of glass (or three), the use of high strength and high air tightness composite binder, the glass and containing desiccant bonding of aluminum alloy frame, highly efficient noise insulation made of glass. A variety of hollow glass performance is superior to the ordinary double deck glass, therefore recognised by the countries all over the world, hollow glass is two or more pieces of glass in order to effectively support evenly separated and peripheral bond seal, with dry gas is formed between the glass layer space of glass products. Its main material is glass, warm edge article interval, corner bolt, butyl rubber, polysulfide rubber, desiccant.
structure
Hollow glass is made up of two layer or multilayer flat glass. Use with high strength and high air tightness around composite binder, two or more pieces of glass and article sealing strip, glass glue, seal. Filling the middle dry gas, box filled with desiccant, to ensure the dryness of the air between the glass. Can choose according to the different performance of glass glass, float glass such as colorless transparent glass, figured glass, absorption heat reflective glass, wired glass, toughened glass and frame (article aluminum frame or glass, etc.), made by cementing, welding or welding.
Its structure is shown in figure double hollow glass section. Hollow glass can be used 3, 4, 5, 6, 8, 10, 12 mm thick piece of glass glass, air layer thickness can be used 6, 9 and 12 mm intervals.
Glass thermal conductivity is 27 times in the air, as long as the insulating glass is sealed, the insulating glass in the best effect of heat insulation.
Hollow glass between glass and glass, leave some space. Box filled with desiccant, to ensure the dryness of the air between the glass. Hollow glass of two layer spacing is commonly 8 mm.
High-performance hollow glass is different from ordinary insulating glass, except in the middle of the two layers of glass sealed in dry air, and air layer between the outer glass side, special metal film coated with a layer of thermal performance is good. It can be as from the sun shoot to indoor considerable energy, play a greater heat insulation effect.
