锡对超薄浮法玻璃热膨胀系数和黏度的影响研究

Study on the Effect of Tin on the Thermal Expansion Coefficient and Viscosity of Ultra-thin Float Glass

渗锡会造成浮法玻璃锡面和空气面成分、硬度等结构以及物理或化学性质有所区别。通过模拟实测浮法玻璃表面成分差异,熔制不同渗锡量的浮法玻璃样品,并对其进行高温热膨胀系数及黏度的测试分析,结果表明:渗锡对浮法玻璃的高温热膨胀系数及高温黏度会有所影响,并且随着SnO_(2)含量的增加,浮法玻璃的热膨胀系数变小,其绝对膨胀量也变小,其黏度则变大。

The differences in the composition,hardness and other physical or chemical properties of the tin surface and the air surface of the float glass were caused by tin infiltration,by simulating the difference in surface composition of float glass,melting float glass samples with different tin infiltration amounts,and testing and analyzing them for high temperature thermal expansion coefficient and viscosity,the results show that:the high temperature thermal expansion coefficient and high temperature viscosity of float glass are affected by tin infiltration,as the content of SnO_(2) increases,the thermal expansion coefficient and its absolute expansion amount of float glass becomes smaller,its viscosity becomes larger.
