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 s4 glass, 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, then heated to near the softening point, then obtain 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, the stress characteristics become an important symbol of true and false identification of tempered glass, glass that 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 white spots. Polarizing sheet can be found at the camera lens or glasses in tempered glass door, to adjust glass light observed, it is easier to observe. 3c has a quality and safety certification mark .. tempered glass with high (4 to 5 times higher than ordinary flat glass) impact strength, flexural strength (5 times higher than ordinary plate glass), heat stabilizers on each glass good and smooth, transparent, can be cut and so on. In the case of impact damage, glass super price, debris was scattered small granular, free of sharp edges, so called safety glass. Tempered glass according to the shape into flat glass and curved glass. 4,5,6,8,10,12,15,19mm eight kinds of flat glass thickness; curved glass thickness 5,6,8mm three. Tempered glass into their appearance quality: superior products, quality products categories. Tempered by debris state is divided into: Class I, Ⅱ and Ⅲ class.
