摘要


本研究利用遇鹼會發泡之鋁粉添加在無機聚合物內,使試體產生孔隙,一方面減輕自重,另一方面發泡之孔隙可以有效地阻絕熱源,增加絕熱效能。本試驗先以不同攪拌時間之無機聚合物製作12cm直徑實心圓試體,進行正面火焰噴燒耐火試驗,因瓦斯噴槍熱源易發散,無法完全達到國內規範CNS12514加熱條件。本研究特別改良加熱設備,並變更試體形狀尺寸為20cm直徑空心圓筒,以規範標準升溫曲線由試體內部進行高溫加熱,量測1小時間試體外側非加熱面之溫度。結果顯示,攪拌時間為20分鐘時,試體內部孔隙分布最均勻,隔熱效果也最好。而其外側面任一位置之溫度均未超過210℃,平均溫度亦未超過170℃,符合規範需求,有填充防火門等實務應用的價值。

The present study added aluminum powder into the geopolymer material to produced pore. It would on one hand reduce weight, and on the other hand effectively isolate the heat source. At first, 12cm diameter geopolymer round cakes specimens by different mixing time were made, and then heated directly using a fire flame jet. However, due to dissipation of the heat, the temperature increased curve could not fully achieved CNS12514 specification. The present research made a special improvement on the heating equipment, and also changed the size and shape of the specimen to a 20cm diameter hollow cylinder. The heating source was putting inside the specimens, and the temperature was measured at the outer surface of the specimens for 1 hour. The results showed that when the mixing time is 20min, the pores distribution inside the specimen were the most uniform and gave the best effect of insulation. The temperatures at any location of the outer non-heated surface did not exceed 210℃, while the average temperature did not exceed 170℃. Both satisfied the requirements of the specification, and would have the practical value of filling fire resistant doors.
