ARES聚合物拉伸黏度的测试附件

| The roots of extensional rheometry are to be found at the very beginning of the 20th century. It was Trouton, who when experimenting with pitch and shoemaker’s wax, subjected these materials to “torsion” and “traction” deformations. He discovered through his ingenious experiments, that the uniaxial extension viscosity is three times the shear viscosity.”.…A variety of pitch which gave by traction method λ=4.3 x 1010 poise was found by torsion method to have a viscosity μ=1.4 x 1010 poise… F.T. Trouton (1906)” |
