Concentrated slurries with (flowing) and without (thick) lignin dispersant.浓缩浆-(流)后(厚)木质素分散.

While the nature of the dispersed systems varies, the function of the dispersing agent is always to control the interaction between fine particles, often solids, suspended in a second medium, often water.虽然性质的,分散系统不一,功能分散剂,也往往是控制相互作用,细颗粒固体的时候,暂停在二中,常水.

Polymeric dispersing agents function by adsorbing at the surface of the suspended particle and thereby provide a protective layer that hinders particle attraction.聚合物分散剂的功能,吸附在表面上的悬浮颗粒,从而提供一个保护层阻碍粒子的吸引力. Sulphonated lignins function as dispersing agents in this way.磺化木质素的功能,为分散剂,在这样的. As anionic polyelectrolyte polymers, sulphonated lignins are prone to adsorption to a wide range of particle substrates.作为聚阴离子聚合物,磺化木质素易吸附各种颗粒物. Consequently, one finds that sulphonated lignins can perform as polymeric dispersants in a diverse range of applications.因此,人们认为,磺化木质素可作为从事聚合物分散在各种应用. 862162181190
