用流变性方法分析了酞菁蓝－醇酸树脂体系的分散稳定性，同时用沉降和电镜等方法对该体系的分散稳定性进行了确证。结果表明，添加９４３分散剂的酞菁蓝－醇酸树脂体系的分散稳定性变好，其流动行为趋近宾汉流体；而未加分散剂的相同体系中，酞菁蓝粒子易于沉降、返粗，其流动曲线形成明显的触变环。
The rheological method was used to analyze the dispersion stability of the phthalocyanine blue-alkyd resin system. At the same time, the dispersion stability of the system was confirmed by the methods of sedimentation and electron microscopy. The results show that the dispersion stability of phthalocyanine blue-alkyd resin with 943 dispersant is better and its flow behavior is close to that of Binham fluid. In the same system without dispersant, the phthalocyanine blue particles are easy to settle, Crude, its flow curve to form a clear thixotropic ring.
