Ceramsite coating additive with core-shell structure and application thereof
The invention discloses a core-shell structure ceramsite coating layer additive and an application thereof, which belong to the technical field of contaminated soil governing, the ceramsite coating layer additive comprises the following raw materials by mass: 20-90% of a fluxing agent; and 10%-80% of a passivating agent. The additive provided by the invention can further enhance the solid sealingeffect of the coating layer on heavy metals, reduce the porosity of a coating layer, increase the compactness of the coating layer, reduce the leaching risk of the heavy metals and realize harmless treatment.
本发明公开了一种核壳结构陶粒包覆层添加剂及其应用，属于污染土壤治理技术领域，该添加剂以质量百分比计，原料包括以下组分：助熔剂：20％‑90％；钝化剂：10％‑80％。本发明所述的核壳结构包覆层添加剂可以进一步增强包覆层对重金属的固封效果，减少包覆层的孔隙率，增大包覆层的致密程度，降低重金属的浸出风险，实现无害化处理。
