 1.Tempered glass Introduction

  Is made by heating flat glass to just below its softening temperature and suddenly chilling it with jets of cold air.It results the outer skins under powerful compressive stress and the interior with severe tensile stress.In consequence,the impact applied to the glass will be overcome by the compressional force on the surfaces t assure safety of use.

The process of tempered glass is to heat the original glass to a very high temperature and cool it down rapidly to form the surface compressive on the glass.According to the shape it can be divided into the fully tempered glass and the heat strengthened glass (also called semi-tempered glass).

   

Feature:

No tong marks on the glass as TG adopts the horizontally tempering process. 5 times harder than ordinary annealed glass. Once breakage occurs,the glass disintegrates into small cubical fragments which are relatively harmless to human body. It withstands abrupt change of temperature..For example ,a piece of 5mm tolerate the temperature variations within the range of 200.

4.More Detail Description

 

Tempered Glass: Float glass that is heated and then cooled rapidly to make it several times stronger than annealed glass. Tempered glass is safer than annealed glass because when it is broken it falls into pebble-like pieces without sharp edges.
Features With high strength, good thermal stability and safety. No sharp edges on broken fragment.Performance Comparison Between Tempered Glass and Normal Glass Test Item 6mmFloat Glass 6mmTempered Glass Bending-resistance strength 50Mpa >150Mpa Impact-resistance strength 227g steel ball dropped from 750mm high, glass is broken 1040g steel ball dropped from 1000mm high, glass is unbroken Thermal stability 70 - 100broken 25O - 327unbroken Broken chipa Sharp edges, can cause damage Pebble-like pieces without sharp edge, safe

Application
Tempered glass is mainly used for glass curtain walls, up-scale shopfronts, shower rooms, escalator rails, windows and doors on balcony, glass partition and areas where glass may have great potential in causing human damages such as public stadium where people are crowded.

 

Note : The tempered glass will sometimes self-blast due to the characteristics itself. The cause is about the NiS.which turns into instability after heating and sudden cooling. The possibility of self-destruction is low, yet it can't be wiped out.To minimize the chances of self-blast,we have large heat-soaked furnace to detonate the potential danger of the tempered glass.Once being heat-soaked,the self-destruction probability will be reduced from 1/1000 to 1/100,000
