溶剂分散
The activity index and angle of contact of different coupling agents were determined, and the effects of solvent, pH, temperature and dispersion time on the modification by silane coupling agent were studied. The results of the modification were characterized by means of FTIR.
考察了溶剂、pH值、温度及分散时间对硅烷类偶联剂改性效果的影响,采用活化指数、接触角以及傅立叶变换红外光谱对改性结果作了表征。
The ethylcellulose aqueous dispersion can be prepared by latex converge, phase change, emulsion-solvent-evaporation, solvent transform.
EC水分散体有乳液聚合 、 相转变 、 乳液 - 溶剂蒸发 、 溶剂变换等制备方法.
