Sludge ceramsite and production method thereof
The invention relates to the technical field of ceramsite, and discloses sludge ceramsite and a production method thereof.The sludge ceramsite is prepared from, by weight, 20%-70% of sludge, 28%-55% of auxiliary materials and 2%-25% of admixture, and the sludge is obtained by treating river or pond sludge; the sludge comprises the following chemical components in percentage by weight: 55%-63% of SiO2, 18%-24% of Al2O3, 6%-10% of Fe2O3, 4.2%-6.3% of CaO, 4.2%-6.3% of MgO, 1.5%-4% of Na2O, 1.5%-4% of K2O and 2%-10% of ignition loss. According to the invention, the ceramsite is produced by taking the sludge as a main raw material, so that the utilization of sludge resources is realized, different auxiliary materials and additives are added according to production requirements, and under the action of the iron tailing sand, the aeration effect in the ceramsite is better, and the water absorption of the ceramsite is ensured; the steel slag powder, the waste glass powder and the like are added into the ingredients, so that the structure of the sludge ceramsite is effectively improved under the action that the content of CaO in the steel slag powder is relatively high, and the stability of the ceramsite is improved.
本发明涉及陶粒技术领域,公开了一种淤泥陶粒及其生产方法,包括以下重量份的原料:淤泥20%~70%,辅料28%~55%和外掺剂2%~25%,所述淤泥为河道或水塘淤泥经处理获得;所述淤泥中的化学成分要求为:SiO2:55%~63%,Al2O3:18%~24%,Fe2O3:6%~10%,CaO:4.2%~6.3%,MgO:4.2%~6.3%,Na2O:1.5%~4%,K2O:1.5%~4%,烧失量2%~10%。本发明中,通过淤泥为主要原料进行陶粒的生产,实现了淤泥资源的利用,并且根据生产需求添加不同的辅料与外掺剂,在铁尾矿砂的作用下,则使陶粒内部的发气效果更佳,确保了陶粒的吸水性,并且通过在配料的内部添加钢渣粉、废玻璃粉等,在钢渣粉内部CaO含量较高的作用下,则使淤泥陶粒的结构被有效改良,提高了陶粒的安定性。
