摘要
烃类溶剂透过ＨＤＰＥ／ＭＰＡ层状聚合物共混物的传质过程符合溶解－扩散模型Ｄ／Ｄ０＝ａ１ｅｂ１／φ。烃类溶剂渗透量Ｊ随温度Ｔ的变化关系为：Ｊ＝ａ２ｅｂ２Ｔ。渗透量Ｊ随时间ｔ的变化初始数天为指数关系，其后符合线性关系；ＭＰＡ的体积分数φ为定值时，温度升高，Ｄ／Ｄ０值下降。
The mass transfer process of hydrocarbon solvent permeating through HDPE/MPA laminar container is fit for the Solution Diffusion model of D/D 0=a 1e b 1/φ . The relation between temperature T and hydrocarbon solvent permeation quantity J is J=a 2e b 2T . In the beginning, permeation quantity J varies exponentially with time t. When t≥t n, J is proportional to the time t. The value of D/D 0 decreases with increase in temperature when volume fraction φ of MPA remains constant.
