摘要(Abstract):
本文采用自制CE—81型毛细管流变仪研究了PET/PE共混物体系的流变性和粘弹性。结果表明:在所研究的温度和切变速率范围内,随PET含量的增加,PET/PE共混物体系的表观粘度η_a以及剪切弹性模量G下降,可复弹性形变Sr及第一法向应力差(σ_(11)—σ_(22))增加。
Model CESI Capillary rheometer is used to study the rheological and viscoelastic properties of PET/PE blends. The result shows that during the ranges of temperature and shear rate under study the recoverable e-lastic deformation and the difference of first normal stress increase as PET proportion of the blends rises,however the apparent viscosity and elastic shear modulus decrease correspondingly.
