分散剂

Polymeric dispersing agents play a critical role in determining the properties of a wide range of materials.聚合物分散剂起着关键作用,以确定性能广泛的材料. This list includes pharmaceuticals, foodstuffs, dyestuffs, agrochemicals, paints, and many other materials where rheology of suspended solid particles is critical.这个清单包括药品,食品,染料,农药,油漆,以及许多其他材料如流变悬浮固体颗粒是至关重要的. Many industrial processes depend on dispersants, such as industrial preparations involving slurries or suspensions.许多工业过程取决于散剂,如工业准备涉及浆或悬浮.

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. 86 21 62181190
