盐碱地改造用高效阻盐材料的制备及其性能研究OA北大核心CSTPCD
Preparation and Study of Properties of High-Efficiency Salt-Blocking Materials for Saline-Alkali Soil Reconstruction System
为改良盐碱土壤,制备了一种隔水阻盐性能优异的超疏水颗粒材料,构建隔水阻盐材料与蓄水模式结合的盐碱地改造体系.以大漠砂为芯材,通过表面覆膜进行疏水改性,探究树脂和微纳米辅材掺量对材料疏水性、抗渗性和透气性的影响规律.利用微型土柱模拟地下水盐迁移过程,探究材料的隔水性能和阻盐性能.结果表明,在树脂、疏水碳酸钙和纳米二氧化硅掺量分别为1.0%、0.8%和0.2%时,材料接触角达到153.6°,耐静水高度达230 mm,并维持良好的透气性能.在微型土柱模…查看全部>>
In order to improve saline-alkali soil,a superhydrophobic particle material with an excellent waterproof and salt-blocking performance was prepared,which was used to build a saline-alkali soil reconstruction system with a water-storage mode.Substrate material and desert sand were modified with a hydrophobic coating.The influences of resin content and micro-/nano-material content on the hydrophobicity,impermeability and breathability of the material were stud…查看全部>>
