Measurement and Modeling of Butene-1/Polybutylene-1 Solution Viscosity
The viscosity (η) of butane-1/polybutylene-1 solutions with different solid content (C) at different temperature (t) and shear rate (γ) was measured and a viscosity model was established.The results indicated that the viscosity of the butane-1/polybutylene-1 solutions decreased with temperature rise,decreased with increasing shear rate and increased with increasing solid content.Under the condition of 10 S-1 < γ < 500 S-1,70 ℃ ≤t≤ 130 ℃ and 2.5%≤ C≤25%,the constant pressure viscosity model for the butane-1/polybutylene-1 solutions was η =2.543 × 10-4y-0.3611 × exp [1 625.53/(t + 273)] × exp(12.76C) with homoscedasticity test value of 17 314.02,confidence level of 0 and correlation coefficient square of 0.946 8.
