氨基磺酸系陶瓷分散剂(ASP)与木质素磺酸钙(木钙)、萘磺酸盐甲醛缩合物(fdn)及磺化丙酮甲醛缩合物(saf)相比具有明显分散降黏效果。测定了四种分散剂在黑泥表面的吸附等温线及其对黑泥颗粒表面 Zeta 电位的影响，结果表明ASP既有较大的饱和吸附量，又能提高黑泥颗粒的Zeta电位，通过静电排斥和空间位阻协同作用表现出优良的分散性能。通过加入脲、氯化钠及柠檬酸钠研究了ASP在黑泥/水界面的吸附作用力，发现吸附过程的主导作用力是络合作用，同时氢键吸附也是重要的吸附作用力。

Compared with ceramic dispersants such as calcium lignosulfonate, napthalenesulfonic acid-formaldehyde condensate (FDN) and sulfonated acetone-formaldehyde condensate (SAF), aminosulfonic acid-based dispersant (ASP) shows better dispersion and viscosity reducing performance. By determining the adsorption isotherms of these four dispersants on black mud particles and studying their influence on particle zeta potential, it is found that the excellent dispersible performance of ASP is due to its large saturated amount of adsorption and the increase of absolute zeta potential of the particles, which results in strong electrostatic repulsive force and steric hindrance among particles. Urea, sodium chloride and sodium citrate were added to study the adsorption force between ASP and black mud particle, and the results indicate that complexation is the main force of the adsorption process, and the hydrogen bonds are also important.
