Abstract

The thickness and deflection of melting parts of the glass edge reach the biggest effect on the intensity and thermal insulation performance. During the sealing process using a hydrogen mixed gas torch, the thickness and the deflection effect of the edge part are affected by process parameters. In order to analyze the correlative relationship of the thickness prediction and the deflection of the edge part according to the process parameters, data was obtained by conducting sealing experiments. The main effects and interaction effects of process parameters for the thickness and the shape of the glass edge parts were analyzed through the design of experiment. A mathematical experiment equation that can predict the thickness and deflection of the edge part according to the process parameters was developed by conducting multiple regression equations.

유리 모서리 접합은 디스플레이 및 건축, 가전 등 산업계의 다양한 분야에 활용되고 있으며, 패널 접합부의 두께 및 형상은 단열성능 및 강도 등 패널의 주요 성능에 큰 영향을 미치는 요인으로 작용한다. 이런 모서리 접합부의 단면은 수소혼합가스토치를 이용하여 모서리를 용융 접합 할 경우 공정변수에 의해 형상이 결정된다. 따라서 본 논문에서는 가스토치를 이용하여 모서리 접합 시 접합부에 영향을 미치는 공정변수를 설정하고, 접합단면의 형상변수를 설정하여 두 변수간의 상관관계를 분석하기 위한 회귀식을 도출하고자 하였다. 회귀식 도출을 위해 공정변수가 형상변수에 미치는 주효과 및 교호작용을 분석하였으며, 변수간의 교호작용을 고려한 다항회귀식을 도출하였다. 도출된 다항회귀식을 통해 각 공정변수 변화에 따라 모서리 접합 두께 예측 및 처짐량 예측이 가능하다.
