摘要
通过改变气体流量、镀膜温度、锡槽保护气用量,研究浮法玻璃在线镀膜参数对热反射合金膜的影响。采用扫描电子显微镜和能谱仪分析膜层的表面形貌、厚度和化学组成,采用分光光度计分析镀膜玻璃的光学性能和颜色指标,并配制5 mol/L的H_(2)SO_(4)溶液测试薄膜的耐酸性能。结果表明,随着气体流量增大,镀膜层厚度增大,膜层颗粒度基本不变,镀膜玻璃透过率、太阳光遮阳系数和玻璃亮度均降低,膜层耐酸性增强。降低镀膜温度,晶粒结合变得疏松,膜层耐酸性降低。关闭锡槽保护气体H_(2),膜层颗粒、厚度减小,玻璃亮度、遮阳系数和膜层耐酸性均有提高。由此可知,任一参数发生变化时,均影响镀膜材料的反应速率,Cr_(2)O_(3)、Fe_(2)O_(3)、CoO等金属氧化物及元素比例改变可影响玻璃的颜色和耐酸性。
The effect of the float glass online coating parameters on the heat-reflective alloy film was studied by changing the gas flow,coating temperature,and the amount of shielding gas in the tin bath.The surface morphology,thickness and chemical composition of the film were tested using scanning electron microscope(SEM)and energy spectrometer(EDS),the optical properties and color indexes of the coated glass were analyzed by spectrophotometer.In addition,the acid resistance of the film was tested by preparation of 5 mol/L H_(2)SO_(4) solution.The results showed that with the increase of gas flow,the thickness of the coating layer increased,the particle size of the coating layer was basically un‐changed,the transmittance of the coating glass,the solar shading coefficient and the glass brightness were all reduced,and the acid resistance of the coating layer is enhanced.When the coating temperature is reduced,the grain binding became loose and the film resistance decreased.Turn off the protection gas H2 for tin tank,the particles and thickness of the film were reduced,and the brightness of the glass,the shading coefficient and the acid resistance of the film were improved.It can be seen that the reaction rate of coating material was affected when any parameter changed.The change in the ratio of metal oxides such asCr_(2)O_(3),Fe_(2)O_(3),CoOand the elements could affect the color and acid resistance of the glass.
