摘要
简要介绍了生命周期评估法,并将其应用在汽车涂装工艺,追踪涂装生产过程中包括碳足迹在内的重要环境足迹,定量化评估汽车涂装过程全生命周期生产活动中各项物料、资源和能源的使用及其产生的排放对生态环境的影响。结果表明,能源消耗及其产生的排放,公用动力、面漆和前处理电泳工序,电网供电对气候变化和化石资源枯竭影响更为显著;而物料消耗及其产生的排放,面漆、密封胶及前处理电泳工序,光伏供电对生态毒性和人体毒性影响更为显著。
The life cycle assessment method was briefly introduced and applied to automotive painting process,the important environmental footprints including carbon footprint during painting production process were tracked,the impact of the use of materials,resources and energy as well as generated emissions on the ecological environment during the whole life cycle production activities of automotive painting process were quantitatively evaluated.The results show that energy consumption and generated emissions,utility power,topcoat and pretreatment electrophoresis processes,and grid power supply have more significant impacts on climate change and fossil resource depletion;material consumption and generated emissions,topcoat,sealant and pretreatment electrophoresis processes,and photovoltaic power supply have more significant impact on ecological toxicity and human toxicity.
