The colloidal particle is the polycondensate of hydrated silica gel (multi-silica acid), belongs to a non-crystalline-state substance.

是具有固体胶态体系，由形成凝集结构胶体粒子构成。

The results show that under microwave irradiation, the intrinsic viscosity and the conversion of the polycondensate are raised.

结果表明，微能提高缩聚物粘数和转化率。
