竹浆黑液高效减水剂与木质素磺酸钠的吸附行为对比
Comparison of Absorption Performance between GCL1-JB and SL
摘要
Abstract
Adsorption behavior and dispersion performance of lignin-type GCL1-JB and SL were investigated. The adsorption behavior of GCL1-JB and SL was studied by self-assembly technology and monitored by QCM-D technology. Adsorption capacity, adsorption film thickness and adsorption layer structure of GCL1-JB and SL on a solid substrate were compared. The experimental results show that GCL1-JB has higher adsorption capacity, thicker adsorption film, more compact adsorption layer, smoother film surface and higher zeta potential on the surface of cement particles. The steric and electrostatic repulsion among GCL1-JB particles are stronger than that of SL, which results in better dispersion performance of GCL1-JB than that of SL. This study shows importance in understanding dispersion behavior of lignin-based water reducing agents.关键词
