概括

山地自行车者平均每100公里磨损3.62克轮胎材料,对总微塑料排放的贡献不到1%,远远低于汽车.

科学领域:

环境科学环境科学
材料科学材料科学材料科学
体育科学运动科学

背景情况:

微塑料 (MP) 研究往往忽略了特定的来源和排放量.
自行车轮胎磨损颗粒 (TWP) 对环境MP的贡献在很大程度上是未知的.
山地自行车在自然环境中直接产生TWP.

研究的目的:

在现实世界使用过程中量化山地自行车轮胎的微塑料磨损.
为了确定山地自行车轮胎的生命周期磨损率.
为了估计德国山地自行车的年度MP排放量.

主要方法:

测量山地自行车轮胎在使用期间的减重量.
对前后轮胎磨损率的量化. 前后轮胎的磨损率.
基于磨损率和循环统计数据计算年度总MP排放量.

主要成果:

每辆山地自行车的中位磨损率为每100公里3.62g.
后轮胎的磨损率 (2.32 g/100 km) 比前轮胎 (1.32 g/100 km) 的磨损率更高.
最初的高磨损率在磨损过多的制造材料后稳定.
据估计,每名山地自行车手每年的MP排放量在59至88g之间.
自行车占每年MP总量的<1%,而机动车轮胎占30%左右.

结论:

重力测量是一种有效的方法来评估自行车轮胎的MP磨损.
与机动车相比,山地自行车是每年MP排放总量的较小来源.
进一步的研究应该集中在其他MP源及其特定的排放因子上.

Rolling Resistance

Rolling Resistance

When a solid cylinder rolls steadily on a rigid surface, the normal force applied by the surface on the cylinder is perpendicular to the tangent at the contact point. However, since no materials are entirely rigid, the surface's reaction to the cylinder involves a range of normal pressures.
For instance, imagine a hard cylinder rolling on a comparatively soft surface. The cylinder's weight compresses the surface beneath it. As the cylinder moves, the material in front of it slows down...
