摘要:
以生活污泥为主要原料,粉煤灰和膨润土为辅料,探讨污泥配方和烧成条件对陶粒各项性能(如堆积密度、比表面积和筒压强度等)的影响. 通过正交试验确定了较为理想的配方和烧成工艺条件:原料配方(质量分数)是污泥约58%,粉煤灰35%,膨润土7%;烧成工艺条件是烘烤温度120 ℃,烘烤时间10 min,烧结温度1 100 ℃,烧结时间45 min. 获得高性能的轻质高比表面积陶粒:堆积密度520 kg/m3,比表面积5.01 m2/g,筒压强度3.05 MPa,产品性能指标达到国家相关标准.
Abstract:
Sewage sludge was used to produce lightweight ceramsites with a high specific surface area. Fly ash and bentonite were used as additives. In the process of manufacturing ceramics,the effects of the firing conditions and ceramic ingredients on properties such as bulk density,specific surface area,cylinder compressive strength of lightweight and high specific surface area ceramic were observed. An ideal formula was obtained indicating that the optimal ingredients (mass percentage) were 58% of sewage sludge,35% of fly ash,and 7% bentonite. The optimal process parameters consisted of a preheating temperature of 120 ℃,a preheating time of 10 min,a sintering temperature of 1 100 ℃, and a sintering time of 45 min. As a result,the product meeting the relevant national standards was obtained. It is characterized by a bulk density of 520 kg/m3, a specific surface area of 5.01 g/m2 and a cylindrical compression strength of 3.05 MPa.
