| 摘 要： | 为确证电子束辐照邮件的可行性,寻找辐照纸张时可保证品种等级的剂量范围,用不同剂量电子束照射新闻纸、复印纸、牛皮纸、书写纸、照片等几种常用的纸张,测定了纸张的定量、白度、撕裂度、抗张强度、耐折度、色差等物理性能发生的变化,并对辐照效应的机理进行了研究.结果分析表明,20-30 kGy的邮件辐照灭菌剂量对上述性能影响小于25%.

| Abstract: | Several kinds of paper such as newsprint, duplicating paper, brown paper and writing paper were irradiated by electron beam with different doses. Some physical properties were measured. When irradiated by 20- 30 kGy, less than 25% of changes occurred on base weight, brightness, tear resistance, tensile strength and folding endurance for duplicating paper, showing that the paper kept at B level after the irradiation. The results are analyzed, and the mechanism of radiation effects is discussed. |
