摘　　要：本实验使用旋转黏度仪测定了Na+、K+、Mg2+、Ca2+离子对羟乙基纤维素(HEC)水溶液体系的黏度的影响。结果表明:本实验采用的HEC具有良好的稳定性和抗盐性能,在本实验所测定的Na+的所有浓度范围,其HEC水溶液的黏度都较其本身要高,而Mg2+浓度高达80%(MgCl2的质量/HEC的质量)时,HEC水溶液体系仍有较高的黏度,这为开发HEC的新用途提供了一定的参考数据。In this paper, we tested the effect of Na^＋ ,K^＋ ,Mg^2＋ ,Ca^2＋ on the viscosity of hydroxyethylcellulose （HEC） in aqueous solution by rotating viscosity meter. The results showed that HEC in the test had good stability and salt-tolerant property. The viscosities of HEC in aqueous solution in existence of all concentration range of Na^＋ in the test were higher than HEC itselfg. What is more, the concentration of Mg^2＋ reached 80%, the viscosity of HEC in aqueous solution still maintained high level. This provided reference data for exploring new application of HEC.
