【摘要】 利用⁶⁰Coγ线对皮张进行杀虫灭菌,其杀虫剂量约1000 Gy,灭菌剂量在15000—20000 Gy之间。本文以抗张强度、伸长率,崩裂强度、撕裂强度、拆裂次数等为指标检查辐照后皮张质量证明,在一定剂量范围内,辐照并不构成对皮张质量的明显影响,并表明,用于消毒的剂量就可杀死赤毛皮蠹虫。更多还原

【Abstract】 has already proved that radiation with ⁶⁰Co γ rays wita dose less than20 kGy possesses a good effect of pesticide and disinfectant. Tensile strength, rate ofelongation, strength of break-up, tearing strength and number of folding break-off ecthave been taken asthe targets for inspecting the quality of hides after being radiated.The inspection proves that within a certain limit of dosage, radiation would not infl-uence obviously the quality of the hides. Besides, it proves that in case a dosage ofdisinfectant or pesticide is used, the radiation would be able to kill reddish fur vermin.更多还原
