Building Tempered Glass is really a type of prestressed cup. In order to improve the strength of the glass, chemical or physical methods are generally used to form compressive stress within the surface of the magnifying glaas. When the glass is afflicted by external force, the floor stress is first balanced out, thereby improving the impact capacity and improving this glass resistance. Pull muscle. The main advantages regarding tempered glass are not one but two. The first is the fact that strength is several times higher than that of ordinary tumbler, the bending strength is Three to five times that of regular glass, and the impression strength is 5 to 10 times that associated with ordinary glass, which elevates the strength. Security. Safety people is the second major good thing about physical tempered glass. Its increased load carrying volume improves the fragile design. Even if the wholesale low-e glass stops working, it will show small fragments without sharp edges, and the damage to the human body is greatly reduced. The quenching and warmth resistance of tempered glass is 2 to 3 times higher than in which of ordinary glass. Usually, it can withstand temperature changes of over 150C, which has noticeable effects on preventing thermal cracking.

Semi-tempered glass is usually called Heat Strengthened Goblet. It is a form of between ordinary flat tumbler and tempered glass. These have the characteristics of substantial strength of tempered a glass. At the same occasion, it avoids the flatness of tempered glass which is easy to self-explosion. Disadvantages such as overall crushing. When your semi-tempered glass breaks, it is radially radial cracked down the crack source, and generally there's no tangential crack propagation, hence the whole can not remain collapsed following the damage. Semi-tempered glass works for curtain wall and exterior window in buildings. It can be made into semi-tempered coated tumbler with image distortion better than tempered glass. However, it should be spotted that semi-tempered glass is not within the safety glass range. As it is broken, there are still sharp fragments which will injure people and cannot be used in skylights and also occasions where human effects may occur. The surface compressive stress of semi-tempered goblet is between 24MPa plus 69Mpa, and the surface stress of tempered glass should be greater than 69MPa. The production process regarding semi-tempered glass is just like that of tempered a glass. The wind pressure should be different in the quenching station, and the resistance to help quenching and heat is a lot less than that of tempered glass.
