1.In present paper, the relation between solution temperature and mass transfer coefficient of volatile substances, such as NH_3, H_2S, SO_2, Cl_2, Br_2, I_2, through gas membranes which are supported by a hollow fiber microporous hydrophobic polypropylene and a flat microporous hydrophobic Teflon film was studied systematically. We found the linear relationshop between natural logarithm of mass tsansfer coefficient, k and negative reciprocal of absolute temperature, T, shown by the formula k=k~0·exp (-A/T).
本文系统地研究了水溶液中挥发组份NH_2、SO_2、H_2S、Cl_2、Br_2、I_2等通过聚四氟乙烯平板膜和聚丙烯中空纤维膜的传质系数与溶液温度的关系,并提出了传质系数K值的自然对数与绝对温度的负倒数呈线性关系,即k=k~0·exp(-A/T)。收藏指正
2.The hybrid double layer film consisting of PTFE and P(VDF-TFE-HFP) is prepared by casting the P(VDF-TFE-HFP) on the surface of Teflon PTFE film.
通过在Teflon PTFE薄膜上经流延一层P(VDF-TFE-HFP)(简称F_(2,4,6))薄膜,形成了具有非均匀机械和电学性质的P(VDF-TFE-HFP)/PTFE压电双层膜。收藏指正
3.Influence of the simulating atomic oxygen in space environment on properties of Teflon FEP/Al film
