    Influence hollow glass qualitative factor energy-saving durability seal life

    Hollow glass must meet two basic requirements: that is energy saving, durability and the seal life. If a hollow glass effect of energy saving is very poor, even if the durability and the seal life long again, is also a low grades of hollow glass. Back, if hollow glass energy saving performance is good, but the durability and the seal life short, also is not desirable. Obviously, the ideal hollow glass should be at the same time with the best energy saving effect and the longest seal durability.

    Influence hollow glass energy-saving performance of the main factors are: glass, article interval (box) and gas. In glass aspects choose to have white glass or low radiation glass, article interval have cold side (aluminum spacing bar) or warm edge, gas have air or inert gases such as argon. In other conditions remain unchanged, using the white glass, air and cold side of the hollow glass effect of energy saving is one of the worst, and with low radiation glass, filled with argon warm side of the hollow glass effect of energy saving is the best.

    Influence of the durability of the hollow glass seal life and the main factors are: insulating glass sealant, seal structure, the article interval, desiccant (molecular sieve) and manual operation quality and so on. It has shown that the double sealing, continuous interval bar and 3 a molecular sieve of the hollow glass sealing the longest life expectancy, and use single channel seal, quadrilateral inserted Angle aluminum spacing bar and 4 a molecular sieve of the hollow glass sealing life is short. North American hollow glass association of hollow glass the usage of 20 years tracking results also proved this point. In addition, hollow glass accelerated aging test (PI detection) the results show that the different structure of the article interval sealing hollow glass expectations are the seal life is great, short just for 2 months, long as high as more than 100 years.

    In other conditions the same situation, different interval of article by directly influence the hollow glass energy saving performance and durable sealing. But for quite a long time, people commonly used aluminum spacing bar (mainly for the quadrilateral inserted Angle) making hollow glass although the seal life longer, but the thermal conductivity is high, the energy saving effect is poor, direct performance in hollow glass edge appear condensation.

    But in the 1970 s, the existence of a composite strip (solid d high strip) has the low heat conduction performance, saving energy is use aluminum article interval making hollow glass has been improved, but unfortunately but at the same time reduce the seal life.

    This kind of unfortunate is manifested in the fact that, in the traditional thinking frame, no matter how people work and improve, improve the hollow glass effect of energy saving and improving the seal life durability, it is not possible.

    In the late 1980 s, two enterprising spirit challenging spirit of the Canadian scientists first developed at the same time solve the hollow glass energy saving and durability of a pair of contradiction method, namely super article interval, in the hollow glass field caused a revolution. Super article interval is to use a without any metal, containing 3 a molecular sieve of silicone microporous structure materials article continuous interval. Its characteristic is minimum thermal conductivity, can greatly improve the hollow glass around the edge of the temperature up to 200 ~ 300% to low radiation glass energy saving effects of 40%, greatly reducing glass around the edge of the condensation degree. Use the article interval making hollow glass with reverse double sealing side method, so that the hollow glass has excellent durability and seal life, for more than 100 years. According to north American use super article interval making hollow glass of the situation, the article use super interval made hollow glass not only energy saving the best performance, and because of its excellent durability and seal life and minimize the after-sales service (complaints). In North America, use the article interval making hollow glass manufacturers to end users to travel the longest period of 20 years of written commitment, and other manufacturers warranty given only for 5 ~ 15 years. To improve the durability of the hollow glass and the seal life significance is, hollow glass energy saving is not only a short-term, static behavior, but a long-term and dynamic concept. In the numerous interval system, super spacing bar is the only can make hollow glass in use period maintained for a long time the best energy saving state article interval. Thus, it to the manufacturer with a direct and indirect economic effect is beneficial to reduce the huge cost of the after-sales service, because product outstanding sex makes its price increase profit margins and increased. From the end user perspective, although its purchase cost is higher, but because of its remarkable energy conservation effect and the seal life brought about by the long-term benefit, make the long-term investment from the comprehensive benefit is very considerable.
