纸张湿抗张强度检测方法的研究
|
摘要
目的研究提高纸张湿抗张强度检测结果准确度的方法。方法选择某湿强纸为样本,通过改变作用于浸湿后样品的擦拭力及其作用时间,测定擦拭后样品的湿抗张力和水分含量,并将最佳擦拭力和擦拭力作用时间下的测试结果与标准方法测得的检测结果作对比。结果当砝码质量为500g,作用时间为15s时,测得纸张湿抗张强度标准偏差由0.4降低为0.1,变异系数由7.18%降低为1.86%,大大提高了纸张湿抗张强度检测结果的准确度。结论为了减少人为因素对纸张湿抗张强度检测结果准确度的影响,可在标准中规定擦拭力和擦拭力作用时间。
The work aims to investigate the method of improving the determination results accuracy of paper wet tensile strength. A kind of wet strength paper was selected as a sample. Wet tensile strength and moisture content of the immersed sample were determined through altering wiping force and its action time after paper was immersed in water, respectively. In addition, the determination results in the best wiping force and action time were compared with the test results obtained by the standard method. The standard deviation of wet tensile strength was reduced from 0.4 to 0.1, and the coefficient of variation was reduced from 7.18% to 1.86% when the wiped farmar quality was 500 g and the action time was 15 s. The determination results show that the accuracy of paper wet tensile strength was greatly improved. In order to reduce the influence of human factors on the accuracy of the paper wet strength test results, wiping force and its action time can be specified in the standard.
