The toughening of glass is to heat the glass to the softening temperature, and then conduct uniform and rapid cooling. The external part of the glass shrinks due to rapid cooling, resulting in compressive stress on the surface of the glass and tensile stress on the inside. To destroy the tempered glass, the compressive stress must be offset first, so that the mechanical strength and thermal stability of the glass can be improved, and the glass has a special fragmentation state.Homogeneous (hot dip) toughened glass means that the toughened glass is placed in a homogeneous (hot dip) furnace, and the nickel sulfide (NIS) in the toughened glass undergoes phase transformation through heating, insulation and cooling. When the volume of nickel sulfide increases, the glass is broken to achieve the purpose of early detonation, thus greatly reducing the self explosion rate of tempered glass.Shandong Yaohua tempered glass excellent characteristics:◆ use domestic famous glass raw materials, cooperate with the most advanced tempering production equipment, and produce high-quality products with professional technology.◆ safety: the glass will be broken into small obtuse angle particles similar to honeycomb, which will not cause major harm to human body.◆ high strength: the strength of tempered glass is generally 4-5 times that of ordinary glass.◆ thermal stability: tempered glass has good thermal stability, can withstand 3 times the temperature of ordinary glass, and can withstand temperature changes of more than 200 degrees Celsius.Shandong Yaohua homogeneous glass excellent characteristics:◆ safety, make nickel sulfide & alpha; The phase is completely transformed into low temperature stable beta; Phase, which can effectively ensure that the tempered glass has no possibility of self explosion;◆ enhance the wind pressure resistance, heat and cold resistance and impact resistance of the glass itself;◆ thermal stability.Product specification: flat steel maximum size: 3300 & times; 13000mm； Minimum size: 150 & times; 300mm； Maximum size of bending steel: 2500 & times; 5000mm   Homogeneous glass: max. 2500 & times; 6000mm ； The average value can reach 1300mmThickness range: 4 ~ 19mmExisting production lines: 2 Glaston tempering furnaces, 2 Hangzhou Seiko tempering furnaces, 1 Taiwan Tongchang tempering furnace and Guangdong ohm.Quality standard: GB 15763.2-2009 and internal control standard sdyh-zy-pz-01
