辐射加工工艺发展趋势及发展我国辐射加工工艺的几点建议

THE ADVANCES IN RADIATION PROCESSING TECHNOLOGY AND SOME SUGGESTIONS

  • 摘要: <正> 辐射加工工艺学的形成虽仅20余年的历史,但在过去的十年中其工业化规模,扩展的领域都有较大发展。辐射加工工艺学是研究和开发利用电离辐射有效地实现某一物理、化学或生物学过程的新学科。到目前为此,它所涉及的主要领域有(1)利用辐射引发交联、聚合和接枝以得到优质化工产品,新材料或具有某种特性的改性材料。(2)利用辐射生物效应对医疗器械用品消毒、中草药灭菌和辐射育种提高农作物产量,对食品辐照以利于储存保鲜,提高食品质量。(3)利用电离辐射引起的某些化学过程对工业三废进行处理等等。由此可知辐射加工工艺是一

     

    Abstract: Radiation processing technology has been made great advances in the last decade especially in the developed cotmtries. According to the conservative evaluation, the total sales of radiation processing products approached about 2—3 billon U. S. dollar in 1981.there after, the processing capacity at least doubles. Now, the intensities of ~(60)Co in use for radiation processing are (5.55—7.40)×10~(18) Bq and there are about 600 sets of electron accelerators for radiation processing. The total sales of radiation processing products are supposed to be over 10 billon U.S. dollar in 1989. However, there are only several fields commercialized. In great scale, such as radiation crosslinked heat shrinkable materials, radiation crosslinked electric cables and wires, and radiation sterilization of medical articles. In China, the radiation processing technology has been developed rapidly in the past years, but the processing capacity is still lower in comparing with developed countries. We suggest that much attention should be devoted to the training of the workers, technicians and managers. The basic theoretical and new technological researches are the keys for developing radiation processing technology at high spced in our country.
