摘要
面对日益匮乏的陶瓷原料,利用固体废弃物来制备发泡陶瓷已是当今趋势。以粉煤灰为主要原料,研究铬渣掺量、碎玻璃掺量和粉磨工艺对粉煤灰发泡陶瓷的影响。结果表明,掺入适量的铬渣可改善粉煤灰发泡陶瓷的性能,小掺量的碎玻璃对粉煤灰发泡陶瓷的性能影响较小。当原料配比为m(粉煤灰)∶m(铬渣)∶m(长石)∶m(碎玻璃)=60∶10∶20∶10时,采用湿法粉磨3 h,可以制得平均孔径为0.64 mm,体积密度为368.54 kg/m^(3),抗压强度为8.11 MPa的发泡陶瓷。
In the face of increasingly scarce ceramic raw materials,the use of solid waste to prepare foamed ceramics has become an inevitable trend.The fly ash was used as the main raw material to study the effects of chromium slag content,cullet content and grinding process on fly ash foamed ceramics.The results show that the properties of fly ash foamed ceramics are improved by adding appropriate amount of chromium slag,and small amount of cullet has little effect on the properties of fly ash foamed ceramics.When the ratio of raw materials is m(fly ash)∶m(chromium slag)∶m(feldspar)∶m(cullet)=60∶10∶20∶10,the foamed ceramics with average pore diameter of 0.64 mm,bulk density of 368.54 kg/m^(3)and compressive strength of 8.11 MPa is prepared by wet grinding for 3 h.
