Inhibiting water evaporation of sandy soil by the soil particles modified with Japanese wax

这研究被进行在沙漠化区域解决砂质土的水保存的问题。土粒的表面被自然的日本蜡的分子通过某特殊屏蔽的表面活化剂修改。修改粒子然后很好被喷洒到沙上，它被交给在一个人工的气候盒子中模仿荒芜的环境，到有压制的效果的一部土壤电影浇的形式并且煤气渗透。土壤电影的结构借助于 X 光检查衍射(XRD ) 和红外线的光谱测定(红外) 被分析。并且它水抑制的机制与 DSC 和 TG 曲线被说明。它对的影响种草通过水的仪器被测试察觉者。结果证明那山梨糖醇酐硬脂酸盐(跨度 80 ) 能很好驱散日本蜡并且让它与也被驱散的泥土结合。在土粒之中的毛孔变得从更小、转弯进吸水恐水病，在哪个方法到通过这部电影渗透的水的抵抗被增加。试验性的草在人工的荒芜的气候盒子中与土壤电影在砂质土上通常成长，显示土粒与日语一起修改了蜡是一个有效方法禁止水蒸发。

This study was conducted to resolve the problems of water conservation of sandy soil in desertification areas. The surface of soil particles was modified by molecules of natural Japanese wax through some specially screened surfactant. The modified particles were then well sprayed onto the sand, which was placed in an artificial climate box with simulating desert environment, to form a soil film with effect of suppressing water and gas-permeability. Structure of soil film was analyzed by means of X-ray diftYaction （XRD） and infrared spectrometry （IR）. And its mechanism of water inhibition was illustrated with DSC and TG curves. Its influence on grass-planting was tested through the instruments of water detector. The results show that sorbitol anhydride stearate （ Span 80） could well disperse the Japanese wax and make it combine with the clay which is also dispersed. The pores among soil particles grew smaller and turned from hydrophilic into hydrophobic, in which way resistance to water penetrating through the film was increased. Experimental grass grows normally on sandy soil with the soil film in the artificial desert climate box, indicating that the soil particles modified with Japanese wax is an effective method to inhibit water evaporation.
