  • 摘要: 采用硅烷偶联剂、钛酸酯偶联剂和铝酸酯偶联剂对石英砂进行表面改性，以制备亲油疏水性滤料。研究得出，钛酸酯偶联剂改性石英砂的最佳工艺条件为：偶联剂用量15%，反应温度90℃，搅拌时间15 min；硅烷偶联剂和铝酸酯偶联剂改性石英砂的最佳工艺条件均为：偶联剂用量15%，反应温度110℃，搅拌时间15 min。水对钛酸酯偶联剂改性石英砂滤料的润湿重量由改性前的1.5589 g降低到0.0282 g，水对硅烷偶联剂改性石英砂滤料的润湿重量降低到0.0607 g，水对铝酸酯改性石英砂滤料的润湿重量降低到0.2664 g。静态吸附实验表明，硅烷偶联剂、钛酸酯偶联剂和铝酸酯偶联剂改性石英砂滤料对油的吸附容量分别增加了33.67%、42.87%和22.30%。XPS和FT-IR分析表明，偶联剂均以化学键的方式包覆在石英砂滤料表面，结合稳定。
    Abstract: The surface of quartz sand filter medium was modified by silane coupling reagent, titanate coupling agent and aluminate coupling agent, respectively. The results showed the optimum conditions to modify with titanate coupling agent were as follows: coupling agent concentration of 15%, reaction temperature of 90℃ and stirring time of 15 min, the same optimum conditions to modify with silane coupling agent and aluminate coupling agent were as follows: coupling agent concentration of 15%, reaction temperature of 110℃ and stirring time of 15 min, respectively. The water wettability weight in the quartz sand pecked column could be reduced from 1.5589 g to 0.0282 g by modification with titanate coupling agent, to 0.607 g with silane coupling agent, and to 0.2664 g with aluminum coupling agent, respectively. In addition, the oil adsorption capacity of quartz sand modified by silane coupling reagent, titanate coupling agent and aluminate coupling agent increased 33.67%, 42.87%, 22.30%, respectively. XPS and FT-IR proved the stable chemical bonds between quartz sand and coupled agents formed after the modification.
