摘要
分析了原纸弹性模量测试的必要性,以定量分别为230g·m-2和350g·m-2的国产牛皮纸为例,参照塑料拉伸和弯曲弹性模量的测试标准,用电子拉伸计测量纸弹性模量。测试结果表明原纸的纵向弹性模量总是大于横向弹性模量,原纸的弹性模量与其定量没有直接的关系。
Analyzing the importance of testing elastic modulus of raw paper, illustrating the test method with 230g·m^-2 and 350 g·m^-2 kraft paper, referring to the test standard of elastic modulus of drawing and buckling for plastics, this paper illustrate the test methods of paper modulus with electron drawing tester. Experiment results show the longitudinal elastic modulus is always more than the transverse one, and the elastic modulus is no direct contact with the gram per square meter.
