【 摘 要 】

With the application of battery becoming more and more widely in our life, the importance of battery production with high quality has been increasingly emphasized. Battery separator is one of the important factors that affect the performance of the battery, so the high functions separator production is particularly important. This article preliminary investigates the effect of pulp types, composition and beating degree on the performances of separator. Main research work:Beating softwood pulp, hardwood pulp and dissolving pulp for different degree by PFI, and papermaking, then detecting the physical properties of paper sheets. Through comprehensive analysis conclude that softwood pulp, hardwood pulp and dissolving pulp have excellent physical properties in the 40° SR, and thermal stability up to 200° in the process of heat treatment. The paper sheets are made using different ratio of softwood pulp, hardwood pulp and dissolving pulp, then test the physical properties. According to the comprehensive analysis of experimental datum obtained that the sheets made using mixed pulp (40° SR dissolving pulp: 40° SR softwood =5:5) have excellent physical performance, and sheet strength index decreased slightly at 200°C, compared to other ratios.
