Explosion-proof construction heat insulation foil techniques:
(1) building explosion-proof insulating films using magnetron sputtering process (more advanced or magnetron sputtering process), on the metallized Mylar surface treated with another layer of polyester film, on the front of the coating layer, back coating adhesives and coating anti-sticking protection film feature films. Posted film on the glass surface to reduce glare, control heat of solar radiation and shade and blocking ultraviolet rays, and other functions, to enhance reflection in the glass and insulation characteristics.
(2) explosion-proof construction heat insulation energy conservation membrane of the outer packaging should be marked: foil types, specification and thickness, performance indicator, color, manufacturer, production technology and production date. Among them, the film thickness is expressed in number of units for a mil or mm.
(3) the construction of explosion-proof energy-saving insulation foil detection sample glass uniform used meets the requirements of GB11614 standard of the float glass 5mm preparation of test specimens for glass-development of colorless transparent glass (glass pastes the membrane preparation of test samples by detecting unit or the Enterprise prepared upon request).
Explosion-proof and heat insulation foil is used to enhance common security application of energy-saving glass dates back to 1960. Development goal for the film at that time, in order to control solar load caused by uneven heating, refrigeration, early film has only the reflection of solar radiation outside the Windows to prevent heat increases the performance of the inner surface of the glass.
With the development of manufacturing technology, a new generation of tinted window film was born, its rich colours for the architect to provide a wide range of design space. Main color: Brown, grey, gold, Grand, blue, green, and so on. 1970 United States energy crisis leads to a film on the performance of development to reduce Interior heat loss ("heat"). Study finds that polyester film not only for transparent media, has more capacity for absorption and inverse long wave infrared radiation. Through trial and error. Big changes in membrane materials and structures to improve film "heat" also had a "low-e film" Low e coating.
