有机颜料表面改性处理(一)

Surface Modification of Organic Pigments(I)

有机颜料改性是在颜料粒子的表面上沉积或包覆单分子或多分子的物质 ,包括表面活性剂、改性剂、颜料本身的衍生物等 ,使粒子的表面极性与使用介质具有更好的相容性 ,以减少粒子聚集 ,提高润湿性、分散性和着色率等性能。

Modification of organic pigments is that sedimenting or covering monomolecular or multimolecular substance on the surface of pigment particles, including surfactant, modifier and derivative and so on, thus surface polarity of particles has better compatibility with usage media, conglomeration is reduced, wetting property and dispersibility are improved.
