轮胎用涤纶帘子布的生命周期评价

Life cycle assessment of polyester tire cord fabric

以汽车轮胎用涤纶帘子布为研究对象,调研了从聚酯聚合、涤纶工业丝生产到帘子布生产这一产业链条上国内典型上下游厂家的能耗与污染排放情况。在此基础上以CML2001生命周期评价体系进行简化生命周期评价,分析了涤纶帘子布生产过程中的主要环境影响因素。结果表明:非生物资源耗竭、全球变暖潜值是涤纶帘子布生产环境影响的主要类型,占总环境影响值的90%以上;涤纶帘子布生命周期的3个主要阶段中,帘子布生产阶段为环境影响的主要环节,占整个生命周期环境影响值的73.8%,该阶段贡献了最多的能源消耗,产生了最大比例的CO_(2)、SO_(2)和NO_(x)排放;在节能减排和绿色可持续发展的大背景下,以涤纶帘子布为代表的产业用纤维及其产品制造行业在生产集约化、提高能效方面尚有较大的提升空间。

Taking polyester tire cord fabric as the research object of the life cycle assessment,the energy consumption and pollution emission of China typical upstream and downstream manufacturers in the industrial chain from polyester polymerization,polyester industrial yarn production to cord fabric production were investigated.On this basis,the life cycle assessment was simplified with CML2001 life cycle assessment system,and the main environmental factors in the process of polyester cord fabric production were analyzed.The results showed that the abiotic depletion potential and global warming potential were the main environmental impact types of polyester cord fabric production,accounting for more than 90%of the total environmental impact value;Among the three main stages of polyester tire cord fabric life cycle,cord fabric production was the main stage of environmental impact,accounting for 73.8%of the environmental impact value of the whole life cycle,which contributed the most energy consumption and produced the largest proportion of CO_(2),SO_(2) and NO_(x) emissions.And under the background of energy conservation and emission reduction and green sustainable development,there is still great space for the industrial fiber and its product manufacturing industry represented by polyester tire cord fabric to improve the production intensification and energy efficiency.
