匀度对芳纶纸各项性能有重要的影响。通过采集纸样图像,利用MATLAB软件进行图像处理,分别获取纸页匀度的灰度直方图和均方差,定性和定量地研究芳纶纸成纸匀度。结果表明,两种方法均可以用来分析芳纶纸的匀度,成纸匀度与纤维配比、纤维形态结构等都有很大的关系。 Uniformity of aramid paper has an important impact on the performance. By collecting the sample images and using MATLAB software to process the images, the gray histogram and the mean square error of the paper were obtained respectively, and the paper quality of the aramid paper was qualitatively and quantitatively studied. The results show that both methods can be used to analyze the evenness of aramid paper. The paper quality is closely related to the fiber ratio and fiber morphology.
