Sensitivity Analysis of Edge Sealing Process Parameters of Vacuum Glazing Panel
The edge sealing process of vacuum glazing panel manufacture is one that requires high reliability in order to maintain a vacuum state between two sheets of glass. In this study, a method of melting and sealing two sheets of glass using the hydrogen mixed gas torch during edge sealing was conducted. During melting and sealing, the deflection effect of the edge part is affected by process parameters such as flow rate of hydrogen mixed gas, moving speed of torch, and distance between the torch and the glass, among others. In order to analyze the correlative relationship of the shape prediction and the sealing shape of the edge part according to the process parameters, data was obtained by conducting sealing experiments and setting shape parameters for the lower melting part. A mathematical experiment equation that can predict the shape of the lower edge part according to the process parameters was developed by conducting nonlinear multiple regression analysis based on the data obtained for the shape parameters. In addition, sensitivity analysis according to the changes in the process parameters was carried out and the effects of the process parameters on the edge shape parameters were analyzed by using the developed mathematical equation.
