摘　　要：合理设置发泡温度和发泡时间是烧制泡沫玻璃的核心工艺.试验设定发泡温度为820、830、840、850和860℃,发泡时间为10、20、30、40和50 min制备泡沫玻璃,研究发泡温度和发泡时间对粉煤灰泡沫玻璃性能的影响.结果表明,发泡温度低于850℃时,随着温度的升高,孔结构差异明显,材料的性能变化较大;当发泡温度高于850℃时,随着温度的升高,孔结构变化小,材料的各项性能指标差异不明显.发泡温度为860℃时,发泡时间应控制在20～40 min,此时材料的导热系数相对较小,力学性能下降不明显,材料孔结构分布也较为均匀.Setting foaming temperature and foaming time reasonably is the core process of burning foam glass. The experiment set 8201830,840,850 and 860℃ as foaming temperature,and 10,20,30,40 and 50 rain as foaming time to study on impact of the burning process on fly ash foam glass performance. The results show that when foaming temperature is below 850℃,pore structure is significantly different and the performance of the material changes remarkably with increasing temperature. When the temperature is exceeding 850℃,pore structure changes slightly and the performance of the material is inconspicuous with increasing temperature. Foaming time should be controlled within a range of 20-40 rain when foaming temperature is 860℃. In this case,the thermal conductivity of the material is comparatively small,and the mechanical properties decline slightly with relatively uniform distribution of the pore structure.
