Hollow glass, invented by Americans in 1865, is a new type of building material that has excellent insulation, sound insulation, aesthetic applicability, and can reduce the weight of buildings， Glass product .
It is a high-efficiency soundproof and heat-insulating glass made by bonding two (or three) pieces of glass with a high-strength and high airtightness composite adhesive to an aluminum alloy frame containing a desiccant. Hollow glass has multiple superior properties compared to ordinary double-layer glass, which has been recognized by various countries around the world. Hollow glass is a glass product that effectively supports and evenly separates two or more pieces of glass, and is bonded and sealed around, forming a dry gas space between the glass layers. The main materials are glass, warm edge spacer, corner bolt, Butyl rubber, polysulfide rubber and desiccant.
structure
Hollow glass is composed of two or more layers of flat glass. Use high-strength and high airtightness composite adhesive around to bond and seal two or more pieces of glass with sealing strips or glass strips. Fill the middle with dry gas and the frame with desiccant to ensure the dryness of the air between the glass sheets. According to the requirements, various glass pieces with different properties can be selected, such as colorless transparent Float glass embossed glass, heat absorbing glass, heat reflecting glass, wired glass, tempered glass, etc., and frames (aluminum frames or glass strips, etc.), which are made by cementation, welding or fusion.
The structure is shown in the cross-sectional view of the double-layer insulating glass. Hollow glass can be made of 3, 4, 5, 6, 8, 10, and 12mm thick sheet glass, and the air layer thickness can be spaced at 6, 9, and 12mm intervals.
The thermal conductivity of glass is 27 times that of air, and as long as the insulating glass is sealed, it has the best insulation effect.
There is a certain amount of space left between the glass and the insulating glass. Fill the frame with desiccant to ensure the dryness of the air between the glass sheets. The spacing between the two layers of insulating glass is generally 8mm.
High performance insulating glass is different from ordinary insulating glass. In addition to sealing dry air between the two layers of glass, a special metal film with good thermal performance should also be coated on the side of the middle air layer of the outer glass. It can cut off the considerable amount of energy emitted from the sun into the room, providing greater insulation effect.
