(1)Tempered Furniture GlassDescription (Tempered Insulating glass;Tempered Laminated Glass) The treatment process of tempered glass is as: When heating glass close molten point, to carry out furnace and rapid cooling treatment on the surface of glass to produce compression stress while it is tension stress inside the glass, thus enhancing the strength and thermal stability. The glass will break into cellular pieces when the external force exceeds its strength. It is hence a highly safety glass. (2)Product Specifications: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. (3)More DetailTempered 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 GlassTest Item6mmFloat Glass6mmTempered GlassBending-resistance strength50Mpa>150MpaImpact-resistance strength227g steel ball dropped from 750mm high, glass is broken1040g steel ball dropped from 1000mm high, glass is unbrokenThermal stability70 - 100broken25O - 327unbrokenBroken chipaSharp edges, can cause damagePebble-like pieces without sharp edge, safeSpecificationFlat tempered glass : Thickness4-19mm Max Glass Size:7000x2440mm n Glass Size:250X150mmFlat tempered glass : Max Glass Size:5200X2440mmStandardGB/T9963-1998 Tempered Glass GB 17841-1999 Tempered Glass and Heat-strengthened Glass for Curtain WallApplicationTempered 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.4)Tempered Strength and Feature 1. Safety: when broken, tempered glass becomes small granules, which prevent substantial hurt to human body.2. High strength: the strength of tempered glass is 4 to 5 times that of annealed glass. 3. Thermal stability: tempered glass has excellent thermal stability, which can withstand up to 300°C thermal shock.Tempered glass is a kind of safety glass and is widely used in places which call for high mechanical strength and safety, such as glazed door, curtain wall, vertical window, partition wall, and partition screen close to heat source and subject to violent thermal shock.4.Features of heat-strengthened glassHeat-strengthened glass differs from tempered glass in its surface compression; its mechanical strength is about 1.6-2 times that of annealed glass. Heat-strengthened glass has outstanding thermal stability, and its flatness is close to that of annealed glass and better than that of tempered glass.SpecificationsDimensions (mm): Maximum dimension: 2440mm x 700mm Minimum dimension: 300m x 300mm Thickness (mm): Tempered glass: 4mm – 19mm Heat-strengthened glass: 4mm -19mmQuality: Conforming to ASTM1048, the American standard conforming to BS6206, the British standard conforming to GB 15763.2, the Chinese standard Conforming to GB17841, the Chinese standard 5)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
