| 摘 要： | 本文介绍了氚在橡胶中的渗透原理,并对10多种橡胶材料的氚渗透性能进行了测量。测量结果表明,天然橡胶的氚渗透系数最大,74氯丁橡胶最小;氚气(HT)对天然橡胶的渗透系数是74氯丁橡胶的1.58倍;厚度为1mm的74氯丁橡胶和天然橡胶膜片达到稳态渗透所需延迟时间分别为72和4小时,相差18倍。

| Abstract: | Tritium permeation Priciple in rubber was introduced in this paper. Permeability of tritium in more than ten kinds of materials weremeasured. The results showed that the permeability coefficient for naturalrubber is the highest and the lowest in 74~# neoprene.Fermeability of tritiumgas (HT) for natural rubber is 1 .58 time higher than that in 74~# neoprene.The time-lag of unstable permeation for natural rubber and 74~# neoprene of1mm thickness is 72 and 4h, respectively.The ratio of the permeabilitycoefficient of tritiated water and NaCl solution to natural rubber and 74~#neoprene is 6.0 and 5.4, respectively. |
