Ordinary broken glass, sharp knife-like sharp corners easily cut your kids, or impactor, resulting in bodily injury. The glass is broken into small particles or a knife like this is to strengthen the way of the most important difference between glass and ordinary glass. Engineering inspection, motionless this destructive inspection is undoubtedly unrealistic.

　　So how can you know whether to buy it is not tempered glass?

　　This had from reinforced glass manufacturing principles to analysis, strengthening of the glass is ordinary annealed glass cut to required size, and then heated to near the softening point, and then a rapid and uniform cooling. Strengthening treatment after the glass surface to form a uniform compressive stress, and the internal tensile stress is formed, so that the properties of the glass can be greatly improved, the tensile strength is more than 3 times the latter, the impact force is more than five times the latter.

　　Precisely this characteristic, the stress characteristics to be a genuine important symbol of tempered glass that is tempered glass colored stripes can see the edge of the glass through the polarizing film, observed in the surface layer of glass, you can see the black-and-white white spots. Polarizing plates can be found in the camera lens or glasses, observation and attention to the adjustment of the light source, which is more easily observed.

　　Each block of tempered glass has a 3c quality and safety certification mark ..
