摘要: 研究了铅铬黄粒子的微胶囊化及其机理;探讨了对粒子表面形貌的量化表征方法。结果表明,在油包水(W/O)乳液中对铅铬黄粒子进行无机微胶囊化是一提高其耐酸、碱性的有效方法。颜料粒子的表面形貌可用其表面分形维数(D)量化表征。

关键词: 铅铬黄, 微胶囊化, 表面形貌, 分形

Abstract: Microencapsulation of lead chrome yellow and its mechanism have been researched and the quantitative method characterization of particle surface shape by surface fractal dimensionality(D)has been investigated. The results showed that inorganic microencapsulation of the lead chrome yellow particles in W/O emulsion is an effective method, raising the acid/baseresistance of the particles.

Key words: lead chrome yellow, microencapsulation, surface shape, fractal
