摘　　要：研究了在TEA质量分数20%～80%,温度40～70℃,剪切速度400～1 000 r/min,剪切时间0.5～2 h的条件下TEA水溶液的流变性。结果表明,TEA水溶液呈现近似Binhanm流型,其表观黏度随TEA水溶液质量分数的增加而增大,随温度的升高和剪切速度的增加而略微降低。TEA水溶液具有触变性,在温度为60℃、剪切速度1 000 r/min和剪切时间1.0 h的优化降黏条件下,质量分数为50%的TEA水溶液于40℃下静置,8 h后其表观黏度基本恢复。Rheological properties of TEA aqueous solution are studied under the conditions of 20 - 80 wt%,40 -70 ℃ temperature,400 - 1000 r/min shear velocity and 0. 5 - 2 h shear time. The results show that TEA aqueous solution presents similar Binhanm flow pattern. Apparent viscosity has a obviously increasing trend with the increase of the concentration of TEA aqueous solution,and a slightly decrease with the increase of temperature and shear speed. TEA aqueous solution has thixotropy. Under the optimal viscosity reduction conditions,namely 60 ℃,1000 r/min shear velocity and 1. 0 h shear treatment,the apparent viscosity of treated 50%TEA solution can basically recover after setting for 8 h at 40 ℃.
