摘要
利用CML环境影响评价方法,研究并比较了植物纤维纸蜂窝和传统芳纶纸蜂窝制备的环境影响。结果表明,针对所涉及的11个环境影响指标,植物纤维纸蜂窝低于芳纶纸蜂窝0.68%~49.41%;权重化结果表明,植物纤维纸蜂窝制备环境影响总体低于芳纶纸蜂窝18.77%;制备芳纶纸蜂窝的环境影响主要来自于芳纶纸和电能的消耗;制备植物纤维纸蜂窝的环境影响主要来自于混杂纸和电能的生产。
The environmental impact of plant fiber honeycomb core was assessed using a life-cycle assessment method using eleven environmental impact categories for the characterization of environmental performance of two manufactured honeycomb cores. The results indicated that after using plant fiber and polyester fiber to replace partial aramid fiber,the environmental impact of plant fiber honeycomb core decreases with a reduction rates ranging from 0. 68 % to 49. 41 % in terms of the eleven categories. The weighting results indicated that the overall environmental impact of plant fiber honeycomb core was 18. 77 %,which was lower than that of aramid paper honeycomb core. The environmental impact of aramid paper honeycomb cores was mainly influenced by the aramid paper production and electricity consumption. Partially replacing aramid fiber with plant fiber and polyester fiber is the reason accounting for the environmental impact reduction.
