动态流变学评价芩榆烧伤凝胶的凝胶特性

目的:应用动态流变学评定芩榆烧伤凝胶的流变性质,评价其凝胶特性。方法:采用剪切速率、频率扫描测定凝胶的流变学参数;采用蠕变方法测定凝胶的黏弹性;采用模拟贮存、运输、使用模式考察凝胶的稳定性。结果:该凝胶为剪切变稀的假塑性流体,具有良好的弹性和黏性,且稳定性良好。结论:动态流变试验能准确的表征芩榆烧伤凝胶的胶凝性质,可作为产品体外评价及质量控制的依据。

Evaluation of Gelling Properties of Qinyu Burns Gel by Dynamic Rheology

OBJECTIVE： To evaluate rheological property of Qinyu bums gel by using dynamic theology, and to evaluate gelling properties. METHODS： Rheological parameters were determined by shear rate and frequency scanning; viscoelasticity was determined by creep experiment. The stability of the gel was evaluated by stimulant modes of storage, transportation and application. RESULTS： Qinyu burns gel was shear-thinning pseudoplastic fluid. Its elasticity, viscidity and stability were satisfactory. CONCLUSIONS： The dynamic rheological experiments can characterize the gelling properties of Qinyu burns gel and provide basis for evaluation in vitro and quality control of products.
