| 摘 要： | 聚芳酰胺纸湿纸页成形后,需要经过热压光作用来提升其各项性能,如机械强度、绝缘性能、平滑度等。本实验通过正交实验研究聚芳酰胺纸的热压工艺,并利用扫描电镜研究了不同热压条件下纸页微观形态,最终确定了聚芳酰胺纸的优化热压条件:热压温度260℃,压力16MPa;预热温度100℃;辊速1.5m/min;次数1次。

| Abstract: | Thermal press process should been carried out to aramid paper alter the wet paper is formed, so as to enhance aramid paper＇s the mechanical properties and electrical insulating properties as well as paper smoothness. There are many factors made the great differences to the properties of aramid paper, such as thermal pressure, times of pressing, velocity of the press roll as well as the temperature of pre-heating. By conducting an orthogonal experiment and using SEM to research the microstructure under different thermal pressing conditions, it made a conclusion that if a higher mechanical property and a higher electrical insulating property are both requested, the folowing conditions are： thermal temperature 260°C, thermal pressure 16MPa, thermal pressing only once, velocity of pressing roll 1.5m/min, temperature of pre-heating 100°C. |
