摘要
介绍了三种晶形改变剂对二水硫酸钙结晶的影响。实验研究表明,利用CR-01,CR-02,CR-03三种晶形改变剂均可改变二水硫酸钙的晶习。由对照条件下的针状分别改变为棱柱状、蝶结状和球状,其粒度也均有明显增大,比表面积仅为对照样的1/3。
The effect of 3 kinds of crystal regulators on di hydrate calcium sulfate crystallization were studied. Experiment results indicated that 3 kinds of crystal regulators such as CR - 01, CR - 02, CR- 03 could modify the crystal form of di-hydrate calcium sulfate from the needle shape of the CK to prismatic, butterfly knot and spherical shapes respectively, the size of crystals were also increased obviously,specific surface area was only 1/3 of that of CK.
