摘要
本文采用落球粘度计和旋转粘度计,研完了纤维素/多聚甲醛/二甲亚砜与聚丙烯腈/二甲亚砜混合溶液在各种条件下的流变学性质。揭示了混合溶液的微观结构及其对流变性影响的作用和机理。
The rheological properties of the mixed solution of cellulose/paraformaldehyde/dimethyl sulfoxied and polyacrylonitrile/dimethyl sulfoxied were studied by rotation viscometry and falling ball methods. The variation of apparent viscosity of the solution was discussed with shear, temperature and its composition. The rheological properties were closely connected with the micro-structures of the mixed solution
