摘　　要：为加强电子烟烟液的质量管控,采用密度计、粘度计、阿贝折光仪对不同丙二醇/丙三醇体系的电子烟烟液和不同含水量和乙醇含量的电子烟烟液进行密度、黏度、折光指数等理化参数的测定,研究了不同丙二醇/丙三醇质量比下各理化参数的变化趋势和不同含水量和乙醇含量对各理化指标的影响,不同温度的黏度和密度的变化趋势,黏度对漏液的影响,以及密度在烟碱含量中的换算关系。结果表明,电子烟烟液的密度、黏度、折光指数随丙三醇质量比增加而升高;水和乙醇能对上述参数起到降低作用;温度越高,黏度和密度越低;黏度较低时,烟弹有发生漏液的风险;密度是提供产品准确成分清单表中的关键参数。结果适用于电子烟烟液建立合理的质量标准及偏差范围,为保证产品质量稳定和查找品质异常提供参考。To strengthen the quality control of E-liquid,the physicochemical parameters,such as density,viscosity,and refractive index,were determined by densitometer,viscometer,and Abbe Refractometer for different pure propylene glycol/glycerol systems and different E-liquid with different moisture and ethanol contents,and the physicochemical parameters,such as water content and ethanol content,were analyzed,Trends in viscosity and density at different temperatures,effects of viscosity on leakage,and relationship between density and nicotine content were converted.The results showed that the density,viscosity,and refractive index of E-cigarette liquids increased with the ratio of propriol;Water and ethanol can play a decreasing role on the above parameters;The higher the temperature,the lower the viscosity and density;When viscosity is low,there is a risk of fluid leakage;Density is a key parameter in providing an accurate compositional list of a product.It is suitable for use in E-liquid to establish reasonable quality standards and deviation ranges,so as to provide a reference for ensuring the stability of the products and finding quality abnormalities.
