Abstract in Chinese为解决干旱地区植树造林中的地表干土层和浇水困难问题而提出黏土引水体材料.对原生膨润土进行层柱化处理并测得了其不同交联剂比例下的材料导水性能,采用X射线衍射、热重、孔隙度分析等测试手段对材料的微结构和热性能进行了表征.研究结果表明,对黏土材料进行改性能显著提高其导水性能,材料的比表面积的增大、孔数量的增加以及孔结构的复杂化是其导水性能改善的主要原因.该材料对提升干旱地区地表层下的水分,提高苗木成活率有明显的效果.
Abstract in EnglishClay-based water-transmitting materials were proposed in order to solve the problems of dry soil layer and watering during forest planting in drought areas. The pillared interlayered clay was prepared in the presence of primary bentonite. The conductivity property was investigated under various conditions of cross-linking agent ratio. The structural aspects and thermal degradation of composites were also studied by means of XRD, TG and porosity analysis. The results indicated that pillared clays modified by Al crosslinking agent exhibit higher conductivity properties remarkably. Larger specific surface area, more pores and complicated pore structures play vital roles in the enhancement of the conductivity property. This kind of material can obviously elevate water from subsurface layer in drought areas so as to improve the survival rate of the seedlings.
