具有环境意识的材料选择

Environment Conscious Material Selection

材料是产品功能和结构的物质载体 ,材料的合理选择对产品的环境性能有重要影响。本文讨论了设计者从环境角度出发在材料选择时应考虑的问题。对资源的丰富程度进行了分类 ,针对塑料制品讨论了材料的可回收性 ,并举例说明了如何结合材料的能容量值进行产品结构的优化设计。

Material selection has direct effect on the environmental ability of the product.To guiding the designers,from an environment point of view,this paper first divides the global resource supply into five classes.Then,taking plastics as example the materials recyclability is discussed,and the concept of energy contained of material is introduced.At the end,some toxic materials are introduced.
