Structural agent for light solidified sludge, solidified soil and preparation method thereof
The invention discloses a structuring agent for light solidified sludge, solidified soil and a preparation method thereof, and belongs to the technical field of solidified soil materials. The structural agent for light cured sludge is prepared from the following raw materials: a sludge curing cementing material, an anti-over-dispersion hydrogen peroxide emulsion/solution, a foaming catalyst and expanded polyphenyl granules, and the anti-over-dispersion hydrogen peroxide emulsion/solution is prepared by mixing and stirring hydrogen peroxide and a high-molecular polymer solution/emulsion. The light-weight sludge solidified soil is prepared from the following raw materials: sludge slurry to be solidified and the structuring agent for the light-weight solidified sludge. By the adoption of the technical scheme, the technical problems existing when the light sludge solidified soil is prepared through an existing physical foaming mode can be effectively solved, and meanwhile the defects that an existing hydrogen peroxide chemical foaming mode is not easy to control, and in-situ foaming of hydrogen peroxide in slurry can be achieved only by heating sludge slurry can be overcome.
本发明公开了一种轻质固化淤泥用结构剂、固化土及其制备方法，属于固化土材料技术领域。本发明的一种轻质固化淤泥用结构剂，该结构剂组分的原料包括淤泥固化胶凝材料、抗过分散双氧水乳液/溶液、发泡催化剂和膨胀聚苯颗粒，其中，抗过分散双氧水乳液/溶液为将双氧水与高分子聚合物溶液/乳液一起经混合搅拌而成。本发明的轻质淤泥固化土，该固化土的原料包含待固化淤泥泥浆以及本发明的轻质固化淤泥用结构剂。采用本发明的技术方案既可以有效解决采用现有物理发泡方式制备轻质淤泥固化土时存在的上述技术问题，同时还可以克服目前双氧水化学发泡方式不易控制以及需要对淤泥浆进行加热才能实现双氧水在泥浆中的原位发泡的不足。
