                                                 Spontaneous Glass Breakage ReportSpontaneous glass breakageSpontaneous glass breakage is a phenomenon by which toughened glass (or tempered) may spontaneously break without any apparent reason.

Laminated glass, also known as laminated glass and vacuum glass, is a composite glass product made of two or more pieces of glass with one or more layers of organic polymer interlayer sandwiched between them, and after special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure process, the glass and interlayer are permanently bonded as one. Laminated glass commonly used interlayer PVB, SGP, EVA, PU, etc., colored interlayer laminated glass, SGX class printed interlayer laminated glass, XIR class LOW-E interlayer laminated glass, etc.

    Safety performance: Laminated glass for architecture can resist the penetration of accidental impact, even if the glass is destroyed, the fragments will still be with PVB film, reducing the risk of breaking or falling glass, it can avoid personal injury or property damage caused by falling glass.PVB film has the function of damping sound waves, so that laminated glass for construction can effectively control the propagation of sound and play a good sound insulation effect.

1, look at the glass markLook at the glass corners to see whether there is a tempered 3C mark, playing 3C mark (the kind that can not be scraped off) is basically tempered glass. Tempered glass processing procedures are first cut into the required size of ordinary float glass, then grinding, cleaning, with ink to play the national mandatory certification ccc mark, into the tempering furnace firing products after the glass is not cut or in the processing. And the ink is generally not scraped off after passing the high temperature.

Even if the glass is broken, the fragments will be stuck to the film, and the broken glass surface will remain clean and smooth. This effectively prevented the occurrence of debris stabbing and penetrating accidents, and ensured personal safety. In Europe and the United States, laminated glass is used for most building glass, which is not only to avoid injury accidents, but also because laminated glass has excellent anti-seismic intrusion capability.

Glass is an item that we often touch and use in our daily life, from household items such as glass to architectural decorative materials such as glass curtain walls, glass has made a great contribution to the development of world civilization. For example, we often hear about tempered glass, which is often used to make various safety and protection products with outstanding performance.

EVA safe glassAlso known as: laminated safety glass evasafe, laminated E.V.A. (ethylene cinyl acetat), laminated evasafe, laminated stadip protect evasafe, laminated stratobel eva creation.Laminated glass with EVA foilRecently, the laminated glass with EVA film used. EVA stands for Etyleen Vinyl Acetate. This film is less sensitive to moisture and is therefore more suitable for outdoor applications of laminated glass.Depending on the required protection, a package can be composed which consists of several thicknesses glass and foil.

The answer is yes, tempered glass is required for buildings over seven stories. When tempered laminated glass is subjected to external forces, it is restricted to resist surface stresses, thus increasing the resistance of the laminated glass itself to air pressure. When this glass encounters external forces, instantly smashed, the fragments will not cause harm to humans, is a relatively high safety factor.About the daily cleaning of tempered glass, just wipe it with a wet cloth, you can also buy a brush to clean the glass, so that the dust on the glass can be wiped clean.

Insulating glass (IG) is separated by two or more glass panes through a vacuum or gas filled space to reduce part of the enclosure through which heat transfer passes. Insulating glass for windows A is commonly referred to as double glazing or double pane windows, triple glazing or triple pane windows, or quadruple or quadruple pane windows, depending on how many panes are used for their construction.The insulating glass unit (IGU) is usually made of glass with a thickness of 3 to 10 mm. Thicker glass is used for special applications.

Thickness of the glass: The heat transfer coefficient of insulating glass is directly related to the product of the thermal resistance of the glass (the thermal resistance of the glass is 1mK/W) and the thickness of the glass. When increasing the thickness of the glass, it will inevitably increase the blocking ability of the piece of glass to heat transfer, thereby reducing the heat transfer coefficient of the entire insulating glass system.
