碩士 === 東方設計大學 === 流行商品設計系 === 106 === Self-Weight Drooping technique for softening vertical flow with electric kiln burning glass plate, is a safe method in the Hot Work of glass,however, during the high temperature kiln firing process, it is not possible to visually determine whether the desired Vertical Flow Length has been reached,in many literatures, the operating temperature reference for this technique has not been found, most creators and manufacturersstill need long-term experimentation to gain an understanding of the relationship between glass temperature and sagging length, so time will increase material consumption. In this study, Clear Float Glass was used as the main experimental material, the difference between 650 °C and 790 °C was 10 °C, it was an electric heating kiln burning temperature rise experiment, there were 15 experimental temperatures, and the experimental 3mm, 5mm, 8mm, 10mm four thickness glass sag the length is varied, the finished product vertical flow length is measured and recorded, the post-experiment data is calculated by a Polynomial Regression equation to find the value of the measured data, bsed on the measured values, the verification results can find the trend line prediction value and the value of the verification result, a value after the decimal point is consistent, which proves the feasibility of the trend line prediction and the actual kiln burning Sagging Length, establishing a method for predicting the temperature and length of vertical flow to achieve the desired shape in the future when making Self -Weight Drooping related operations, you can quickly understand the characteristics of Clear Float Glass to master this technology, and improve past repeated experiments and material consumption. It is recommended that glass expansion experiments with different expansion coefficients be performed in the future, and research data can be inserted to modify and establish another set of actual data to expand the range of material use and operational possibilities.
