Building templates folding edited this paragraph ordinary glass broken sharp knife-like sharp corners is easy to cut child or impactor, causing personal injury. After the glass is broken into small particles or knife-like glass and ordinary glass that is the main difference between the way. But in the engineering inspection, frequently use this destructive inspection is undoubtedly unrealistic. So how can you know whether to buy it is not tempered it? This has to be analyzed from the glass manufacturing principles, ordinary annealed glass, tempered glass is first cut to the desired size glass table, and then heated to near the softening point of 12mm tempered glass, and then obtain a rapid and uniform cooling. After treatment of steel glass surface to form a uniform compressive stress, and the internal tensile stress is formed, the performance of the glass can be greatly improved, more than three times the tensile strength of the latter, the impact force is more than five times the latter. It is this characteristic of glass, the stress characteristics become an important symbol of true and false identification of tempered glass that is tempered glass can be seen through polarized light colored stripe on the side of the glass sheet, and in the observation of the surface layer of the glass, you can see the black and white spots. Polarizing sheet can be found at the camera lens or glasses, to adjust the light source observed, it is easier to observe. On each glass has a quality and safety certification mark 3c glass .. After defining the heat treatment process, the glass surface should be pressure layer glass windows, mechanical strength and thermal shock strength is improved, and the state has a special pieces. Tempered glass Features Security: When the glass is broken force debris into a honeycomb-like particles Suixiao obtuse angle to reduce damage to human body. High strength: the impact strength of glass of the same thickness is 3-5 times that of ordinary glass bending strength is 3-5 times that of ordinary glass. Thermal stability: Tempered glass has good thermal stability, can withstand the temperature difference is 3 times that of ordinary glass, can withstand 200 ℃ of temperature changes. Non-cutting nature: steel rear glass can not cut, drill or change shape. 5mm tempered glass, glass Heze, Yaohui glass factory direct offer from Jinan Glass Co., Ltd. Yaohui.
