Rice hull ash-based nano silicon dioxide modified ash geopolymer antifouling separating wall material and preparation process thereof
The invention provides a rice hull ash-based nano silicon dioxide modified ash geopolymer self-healing separating wall material and a preparation process thereof, nano silicon dioxide prepared from rice hull ash is used as a reinforcing material of an ash geopolymer, and rice hull is fully burnt by a muffle furnace; the problems of insufficient combustion of organic matters and atmospheric environment pollution caused by a large amount of released flue gas in an uncontrolled rice husk combustion process are avoided; the rice hull ash is subjected to impurity removal by adopting hydrochloric acid dipping, the risk that harmful gas is released in the process of removing impurities by adopting nitric acid in the traditional process is avoided, and meanwhile, resource utilization of biomass solid waste is realized by preparing nano silicon dioxide from the rice hulls, and the cost is relatively low; industrial solid waste is adopted as a main raw material of the separation wall, so that the construction cost of the separation wall is greatly reduced, and resource treatment of the industrial solid waste is realized; the rice hull ash-based nano silicon dioxide is adopted to reinforce the ash geopolymer, so that the dry-wet cycle durability of the material is effectively improved, and a novel material with low carbon, low cost and high durability is provided for the construction of the antifouling isolation wall.
本发明提供了一种稻壳灰基纳米二氧化硅改性灰渣地聚物自愈合隔离墙材料及其制备工艺，采用稻壳灰制备纳米二氧化硅作为灰渣地聚物的强化材料，用马弗炉对稻壳进行充分的灼烧，避免不受控制的稻壳燃烧工艺有机质燃烧不充分及释放大量烟气污染大气环境问题；采用盐酸浸渍对稻壳灰进行除杂，规避传统工艺采用硝酸除杂过程释放有害气体的风险，同时稻壳制备纳米二氧化硅实现了生物质固废的资源化利用且成本较低；采用工业固废作为隔离墙主要原材料，大幅降低了隔离墙建造成本并实现了工业固废的资源化处置；采用稻壳灰基纳米二氧化硅对灰渣地聚物进行强化，有效的提升了材料的干湿循环耐久性，为防污隔离墙的建造提供了低碳廉价高耐久的新型材料。
