摘要
Abstract
Spherical MgCl2 is an efficient support for Ziegler-Natta catalyst and suitable for the preparation of catalysts for propylene polymerization.The MgCl2 support has significant influence on the morphologies and properties of the catalysts and polymers.The preparation process of the spherical MgCl2 support is one of the core technologies in such catalyst development.This paper presents the advantages of the MgCl2 support, analyzes the effect of milling activation and chemical activation on the properties of MgCl2.The characteristics of the preparation processes of the spherical MgCl2 support including high-speed stirring, tubule extrusion, spray shaping, shearing emulsification and high gravity are discussed in detail.It is pointed out that the intensification of the emulsion mixing is the controlling factor in the preparation of MgCl2 support,and good emulsion mixing is the prerequisite for the preparation of spherical MgCl2 support with regular morphology and narrow size distribution.关键词
