本文对 PVC 超滤膜的浇铸膜溶剂体系蒸发速度进行了研究,着重讨论了第二添加剂的种类和含量对蒸发速度的影响.结果表明,溶剂蒸发速度及蒸发时间都是影响 PVC 超滤膜结构与性能的重要因素,而二添加剂又是影响溶剂蒸发速度的一个重要因素.
In this paper, the evaporation rate of PVC membrane was studied, and the influence of the type and content of the second additive on the evaporation rate was discussed.The results showed that both the evaporation rate and evaporation time of the solvent affected the structure of PVC ultrafiltration membrane And performance of the important factors, and two additives and solvent evaporation rate is an important factor.
