Study on optimum technological condition of Polyvinyl alcohol-Alumina diaphragm

Heping Zhang

Abstract

Polyvinyl alcohol-Alumina diaphragm was prepared by vacuum adsorb method in this paper.The writer used orthogonal experiment method to measure the diaphragm performance in different technological conditions and do range analysis of the experiment results.The study found that the use level of polyvinyl alcohol has an important influence to the electrochemistry performance of the diaphragm.The optimum technological condition to prepare Polyvinyl alcohol-Alumina diaphragm was confirmed as 5 g of polyvinyl alcohol,40 g of sodium chloride and 75 ℃ temperature.
