The Difference Between Tempered Glass And Semi - Tempered Glass
Jul 07, 2017

  The difference between tempered glass and semi - tempered glass

  Tempered glass is annealed glass through high temperature and quenching, the surface layer to form a strong compressive stress, so that the mechanical strength of glass increased several times, that is, tempered glass. Tempered glass surface stress: 69 ~ 168Mpa. Its characteristics are broken after the broken small obtuse angle particles, the human body will not cause significant harm. Strength is 4 times the normal glass strength and above. Has a good thermal stability, ordinary glass steel can withstand the temperature difference of about 180 ° C. Tempered glass is easy to blew, flatness is poor.

  Semi-tempered glass is annealed glass through high temperature and quenching, the surface layer to form a compressive stress of less than 69MPa, so that the mechanical strength of glass increased several times, that is, semi-tempered glass. Semi-tempered glass surface stress: 24 ~ 69Mpa. Its broken and ordinary glass, the product is characterized by semi-tempered glass strength is more than 2 times the annealing glass. Safety: debris when the fragment was radial, each fragment is extended to the edge, not easy to fall off, safer, but does not belong to safety glass. Deflection: Semi - tempered glass is larger than the tempered glass. Thermal stability: thermal stability is also significantly better than annealing glass, ordinary glass semi-steel treatment can withstand the temperature difference of about 75 ° C. Semi-tempered glass will not blew.

  The use of semi-tempered glass

  Semi-tempered glass in the building for curtain walls and windows, can be made of coated glass, the image distortion is better than tempered glass.
