玻璃喷雾钢化工艺研究

Study of Glass Spray Tempering Process

喷雾钢化工艺理论上比气冷钢化工艺更节能,为了探究喷雾钢化工艺的实际节能效果,本文采用尺寸为40 mm×40 mm×5 mm的平板玻璃进行了气冷钢化和喷雾钢化试验。结果表明:与气冷钢化工艺相比,喷雾钢化工艺在冷却过程中至少节能25.06%;喷雾钢化工艺可以提高玻璃的钢化程度,即破碎后的颗粒数增加了至少8.91%,表面压应力提高了至少12.12%;随着雾载分数的增加,冷却时间减少,节能效果和钢化程度提高。

The spray tempering process is theoretically more energy-efficient than the air-cooled tempering process.In order to investigate the actual energy-saving effect of the spray tempering process,the plate glass with dimension of 40 mm×40 mm×5 mm were used for air-cooled tempering and spray tempering tests.The results show that compared with air-cooled tempering process,the spray tempering process saves at least 25.06%energy during cooling.The spray tempering process improves the tempering degree of glass,that is,the particle number of broken increases by at least 8.91%,the surface compressive stress increases by at least 12.12%.With the increase of mist load fraction,the cooling time decreases,and the energy saving effect and tempering degree increase.
