摘要
对比了国产X612N–2mil型与进口T412–2mil型芳纶纸在厚度、定量、吸水性及透气度等方面的差异,通过扫描电子显微镜表征了两者的表面形态,初步试验了国产芳纶纸对涂胶工艺的影响。结果表明国产X612N–2mil芳纶纸具有厚度小、定量小、吸水性大、透气度大及表面孔洞多的特点,国产芳纶纸表面吸水性正面比T412–2mil高679.7%,表面吸水性反面高838.8%,透气度比进口芳纶纸大约10倍,国产芳纶纸涂胶压制后,其节点强度和白蜂密度(未浸胶)均高于进口芳纶纸,节点强度高26.8%,白蜂窝密度高10.8%。针对国产芳纶纸的特点,以生产过程中节点强度(≥4 N/cm)的要求,开展了节点强度与国产X612N–2mil型芳纶纸透气度、涂胶速度、胶液黏度三者的关系研究,通过单一因素与节点强度的数据分析,建立纸张透气度/涂胶速度/胶液黏度模型并验证,结果表明根据不同透气度的纸张,可得出涂胶速度、胶液黏度主要工艺参数的区间,为涂胶工艺提供理论指导,有利于拓展国产芳纶纸在芳纶纸蜂窝领域的应用。
The differences in thickness,basis weight,water absorption,and air permeability between domestic X612N–2mil and imported T412–2mil aramid papers were compared.The surface morphology of the two was characterized by SEM.In addition,the preliminary test the domestic aramid paper effect on printing process which shows that the domestic X612N–2 mil aramid paper has the characteristics of small thickness,small basis weight,large water absorption,large air permeability and more surface holes than imported one.The front surface water absorption of domestic aramid paper is higher 679.7%than imported aramid paper,the back surface water absorption is higher 838.8%,and the air permeability is about 10 times higher than imported aramide paper.After domestic aramid paper is printed and pressed,the node bond strength and white core density(un-dipping)are higher than imported aramid paper,with 26.8%higher node strength and 10.8%higher white honeycomb core density.According to the characteristics of domestic aramid paper,the relationship of the node bond strength between the air permeability,printing speed and glue viscosity of domestic X612N–2 mil aramid paper was studied.According to the requirements of node bond strength(≥4N/cm)in the production process.Based on the analysis of single factor and node bond strength data,the paper air permeability/printing speed/glue viscosity model was established and verified.The results show that according to different air permeability papers,the main process parameters of printing speed and glue viscosity can be obtained.This range data could provide the theoretical guidance for the printing process,and the application of domestic aramid paper in the aramid paper honeycomb field is expanded.
