疏水缔合聚合物在石英砂表面的吸附——疏水基含量和微嵌段长度对吸附的影响
Adsorption of Hydrophobically Associating Polymer on Sand:Influence of Hydrophobe Content and Micro-block Length
摘要
Abstract
The static adsorption properties of several water soluble polymers, including different kinds of partially hydrolyzed polyacryamide ( HPAM ) and hydrophobically associative water soluble polymers (HAWSPs), have been studied at 45 ℃, 55 ℃ and 65 ℃. The results show that the maximum adsorption of HAWSPs on sand is affected by the hydrophobe contents and the lengths of micro-block, with the former one playing the major role. The isothermal adsorption curves show two platform areas. The maximum adsorption of HPAM rises with the increase of temperature, but the situation for HAWSPs is in the contrary. It indicates that the hydrophobe contents and the lengths of micro-block may affect the adsorption.关键词
