According to the hollow glass place of use difference, the use goal is different, the hollow glass uses raw material and the structure are also different.If in the south area, the whole year temperature is high, the illumination time is long, when use hollow glass in, many considerations are control exterior quantity of heat to be able little to enter enter the inner rooms, when choice hollow glass prototype, can more consider the use coating glass; In the northern area, in the use the hollow glass main purpose is the heating and the heat preservation, therefore can many consider selects the clear glass to make the spatial glass prototype.But in needs to control the noise the place, needs to use three or the gasification.
Along with the economical development, the hollow glass product variety also had many development, uses raw material variety also along with increase.If curtain wall with hollow glass; Automobile, train with hollow glass; Electric appliance with spatial glass; For decorative or ornamental purpos the hollow glass (including crustification with the hollow glass, color crystal sets up in line hollow glass) and so on.All these products, because although the use is different, use raw material is different, but the basic composition is same, namely:
Glass - - all plate glass and the intensive processing product, are in the constitution the hollow glass fundamental component;
The aquaseal - - to the hollow glass, side carries on the seal, guarantees the few steam to enter hollow glass in as far as possible, the expiration time which in the extension gets off work spatially;
The drying agent - - guarantee will seal in the hollow glass interior all steam adsorption is clean, and will adsorb along with the time the passage will enter the hollow glass internal steam, in the guarantee the hollow glass life;
Separates in the strip - pneumatic control the hollow glass inside and outside two glass spacing, and controls exterior steam to isolate completely in this part, guaranteed the hollow glass has the reasonable hollow level thickness and the service life.
We may see from above: In constitution in hollow glass all raw materials, aquaseal and drying agent performance the quality, affects in a big way to the hollow glass product service life; When consideration energy conservation question, the space stop bar and the sealant heat conduction performance quality directly will affect the hollow glass side heat insulation performance, thus influence windows and doors whole heat insulation performance.
The hollow glass production technology passes through several dozens year development courses, its itself unceasingly is also consummating, the product heat insulation, the sound-insulated performance, from the earliest process of welding, the fusion law to the cemented aluminum strip law, the product heat insulation, the sound-insulated performance had the very big enhancement.After after 70's petroleum crises, the people discovered that, the aluminum strip law product side heat insulation performance is bad, must perform to improve, can enhance the hollow glass whole heat insulation performance.To the 80's initial period, in the world first warm side systematic hollow glass being published, this is in the solid only high (Swiggle) block glue system the hollow glass.This kind of hollow glass, the edge heat insulation performance was improved, because the block glue sealing property obtained the enhancement, the service life is longer, the hollow glass whole heat insulation effect was better, enable the hollow glass product market application to have a broader prospect.
