【摘要】 为确证电子束辐照邮件的安全性,探索辐照纸张时可保证品种等级的剂量范围,在不同剂量下,用电子束照射新闻纸、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、色差等物理性能在辐照后发生的变化。并对结果进行了分析,在邮件辐照灭菌20-300kGy的剂量下,对上述纸张的性能影响小于25%,并对辐照效应的机理进行了研究。更多还原

【Abstract】 Several kinds of paper as newsprint, duplicating paper, brown paper, writing paper, were irradiated by electron beam with different doses. Physical properties as base weight, brightness, tear resistance, tensile strength, folding endurance, chromaticity, were measured. The results are analyzed, and researches concerning the mechanism of radiation effects are carried out.更多还原
