破乳剂对预交联颗粒凝胶界面扩张流变的影响
Effect of demulsifiers on interfacial dilational rheological properties of performed particle gel
摘要
Abstract
The effects of nonionic polyether demulsifiers with star-type ( PES) , comb-type ( PEB) , branched structure ( PEB) and cationic reverse emulsifier (HY01) on interfacial film of preformed particle gel (PPG) were studied by interfacial dilation-al method. The experimental results show that the nonionic polyether demulsifiers displace PPG molecules at the interface by competitive adsorption, which decreases the interfacial dilational modulus and weakens the film strength. The star-typed demul-sifier has significant effect on the interfacial structure. The reverse demulsifier influences the PPG interfacial film properties through the electrostatic interaction, which leads to the higher interfacial film strength due to the formation of interfacial com-plexes at certain concentration. However, reverse demulsifier with high concentration could also destroy the interfacial film.关键词
