摘要

現今部分建築物外牆及隔間已有使用防火玻璃案例。但由於防火玻璃耐候性不佳，劣化後會產生氣泡及霧化現象，除外觀受影響外，對建築物防火性能也會產生疑慮，而國內外目前並無相關探討。故本研究以預備試驗及正式實驗進行透光率及防火性能的研究。研究成果如下：
1. 環境溫度為36~42℃時，相對透光率隨劣化時間增加而降低，約四年後會完全劣化；環境溫度為47~58℃時溫度越高相對透光率衰退速度越快，約0.35年後會完全劣化。
2. 半劣化單層防火玻璃相對透光率28.20%，阻熱性能自30分鐘提升至53分30秒；全劣化單層防火玻璃相對透光率10.02%，阻熱性能自30分鐘提升至34分24秒。
3. 當環境溫度小於42℃時，單層防火玻璃主要劣化因子為紫外光；環境溫度大於42℃時則受溫度影響更甚於紫外光。
4. 防火玻璃劣化後不影響防火性能

Modern external walls and compartments in buildings already utilizes fireproof glass as building materials. However such glass can form bubbles and fog up as it is subject to weathering, casting doubt to the fireproof properties of the glass in addition to the changes to the external appearance. Currently there are no further investigations into the subject internationally. This study prepares and formally test the fire resistant properties of fireproof glass and its light transmission from light weathering. The study show that:
1. Light transmission reduces as light weathering time increase in 36~42℃and completely weathers in 4 years time. Increased temperature to 47~58℃will rapidly increase weathering rate and reach complete weathering in 0.35 years.
2. Half weathered single layer gel glass has a relative light transmission of 28.20%, heat resistance increased from 30 minutes to 53 minutes 30 seconds. Completely weathered single layer gel glass has a relative light transmission of 10.02%, heat resistance increased from 30 minutes to 34 minutes 24 seconds.
3. When environmental temperature is below 42℃, the main cause of weathering to single layer gel glass is Ultra violet light. When above 42℃ the main cause of weathering is temperature rather than UV weathering.
4. Fireproof glass do not influence fire resistance properties due to weathering
