溶剂组成对电热蚊香液挥发特性影响的初步研究

目的揭示电热蚊香液散发过程的机制，解释电热蚊香液的实际挥发特征。方法分析电热蚊香液使用时的传质过程，建立数学模型，并通过实验进行证明。结果建立了可以解释电热蚊香液实际挥发特征的数学模型，揭示了溶剂组成对蚊香液各组分散发速率的影响程度。结论药液通过芯棒散发这一结构，决定了蚊香液中的各个组分能够按配方比例均衡地挥发，溶剂的纯度对蚊香液的挥发特性无显著影响，采用高纯度的十四碳正构烷烃作为溶剂没有必要性。

Elementary research on effect of solvent''''s purity against mosquito vapor''''s volatilization

Objective To discover the mechanism of mosquito vapor's volatilization and explain actual volatilization property of mosquito vapor.Methods A mathematic model was set up,which can explain mosquito vapor's volatilization,and prove such model by experiment.Results The mathematic model had been set up.This model discovered the effects of solvent's purity against the volatilization speed of each ingredient in mosquito vapor's liquid.Conclusion The structure of liquid volatilizing through wick makes each ingredient be released evenly according to the formula proportion.The purity of solvent has no sigificance to the volatilization property of the mosquito vapor.It is not necessary to adopt n-tetradecane in high purity as solvent of the mosquito vapor.
