| 中文摘要: |
| 利用干化沼渣作为造孔剂加入烧结墙体材料原料体系中,可制备具有节能效果的烧结墙体材料.通过实验研究了沼渣掺量、烧结温度和烧结保温时间对节能烧结墙体材料的物理性能、力学性能和工作性能的影响规律,结果表明:利用沼渣作为造孔剂加入到原料体系中可获得较好的塑性成型能力,将沼渣掺量控制在10%、烧结温度制度控制在1000 ℃并保温3 h时,能够制备出满足MU10(GB 5101-2003)各项性能指标条件并符合环境保护要求的烧结墙体材料.这为沼渣的综合利用提供了工艺技术方面的指导和借鉴. |

| This study explored the feasibility of dried biogas sludge as a blowing agent in sintered block's material system to produce energy-efficient porous sintered shale block. The influences of biogas sludge dose, sintering temperature and soaking time on physical, mechanical and working properties of the sintered wall materials were studied. Results showed that biogas sludge could be used as raw material to product sintered block with excellent plastic forming ability. The blocks sintered with biogas sludge dose of 10% in mass at 1000 ℃ for 3 hours showed the best mechanical properties. All performance indexes of the product met the requirements of the national standards for sintered common bricks[MU10(GB 5101-2003)] and the environmental protection standards. These results could shed light on new utilization of biogas sludge. |
