摘 要: 以玻璃粉为主要原料,石墨为发泡剂,按一定烧结工艺制备了泡沫玻璃。研究了发泡温度、保温时间及发泡剂掺量等工艺因素对泡沫玻璃的表观形貌、密度、孔径大小和气孔分布的影响,以此来优化制备泡沫玻璃的工艺因素。实验结果表明:当发泡温度定为880℃时,发泡均匀,且明显减少连通孔的数目;当保温时间为10 min时,泡径较大,发泡也较均匀;添加2%的石墨发泡剂能明显增大气孔率和孔径大小,改善制品的发泡质量;球磨时间为2 h时,混合较充分,制品气泡结构较好。
关 键 词: 玻璃与非晶无机金属材料;泡沫玻璃;优化;发泡温度;保温时间;石墨发泡剂

Abstract: Foam glass was prepared by sintering process, using powder of waster glass as main raw material and graphite as foaming agent. In order to optimize the prepared technological parameters, the influence of parameters, such as foaming temperature, holding time, amount of foaming agent, etc, on the apparent structure, density, pore diameter and distribution has been studied. The result of experiments showed that when the foaming temperature is 880℃, the pores are uniform and the amount of connected pores is reduced; the pore diameters increase and are more homogeneous for holding 10 minutes; adding 2% graphite foaming agent can obviously increase the porosity and the diameter, as well as improve the foaming properties; ball-milling for 2 hours can mix the raw material well, and improve the pore structure.
Key words: glass and amorphous inorganic metal materials; foam glass; optimize; foaming temperature; holding time; graphite foaming agent
