摘要
目的研究自1988年首次发布水泥包装袋国家标准以来我国水泥包装袋标准化历程,为标准的修改提供参考。方法通过分析历次水泥包装袋国家标准(GB 9774、GB/T 9774)修订内容,从水泥包装袋的分类、制袋材料、袋型、物理力学性能、适用温度、牢固度、防潮性能等方面阐述水泥包装袋制袋技术标准化的更新改进。通过2018—2020年水泥包装袋产品质量普查,从防潮性能、物理力学性能、弃缝改糊、禁塑令、绿色包装等方面阐述水泥包装袋标准化必要性。结果通过对比水泥包装袋新旧标准中防潮性能测试方法与指标要求,得出了水泥包装袋防潮性能标准化的趋势。结论我国水泥包装袋制袋国际化程度较低,标准化工作需要进一步与国际接轨,以引领水泥包装产业发展。
This paper studied the standardization course of cement packaging bags in China since the first release of the national standard for cement packaging bags in 1988,so as to provide reference for the revision of the standard.By analyzing the revisions of the previous published national standards for cement packaging bags(GB 9774 and GB/T 9774),and the updates and improvements in standardization of bag making technology of cement packaging bags were expounded,from the aspects such as the classification of cement packaging bags,bag making material,bag type,physical and mechanical properties,applicable temperature,firmness,moisture-proof performance,etc.Through the 2018-2020 census of product quality of cement packaging bags,the necessity of standardization of cement packaging bags was ex-pounded from the aspects of moisture-proof performance,physical and mechanical properties,changing seams to paste bottom bag,plastic prohibited order,green packaging,etc.By comparing the test methods and index requirements of moisture-proof performance in the new and old standards of cement packaging bags,this paper expounds the trend of standardization of moisture-proof performance of cement packaging bags.The degree of internationalization of cement packaging bags in China is relatively low,and the standardization work needs to be further in line with international standards to lead the development of the cement packaging industry.
