概括

将退役渔网 (FN) 回收成青粘合剂可以提高道路材料的刚性和高温性能. 然而,需要谨慎剂量,以保持耐疲劳性和耐久性.

科学领域:

材料科学材料科学材料科学
环境工程环境工程
土木工程土木工程是指土木工程.

背景情况:

废弃渔网管理不当导致严重的环境污染,影响海洋生态系统.
道路建设中越来越需要可持续的做法,包括使用回收材料.

研究的目的:

调查使用寿命已结束的渔网 (FN) 作为青粘合剂的修饰剂的再利用的可行性.
通过提高青的可回收性,促进道路建设中的循环经济模式.

主要方法:

在不同的剂量中将渔网 (FN) 纳入青粘合剂中.
评估青粘合剂的性能,包括复杂模量 (G*),刚性和高温耐受性.
在20°C的VECD模拟以评估循环负荷和低温下的疲劳寿命.

主要成果:

鱼网 (FN) 的加入增加了复杂模量 (G*),增强了刚性和耐高温性,特别是在6%和9%的剂量下.
由于FN增加的刚性可能会在低温和循环负荷下损害耐疲劳性.
VECD模拟显示,在5%的应变和20°C时,最小的FN结合使疲劳寿命减少了40.61%.

结论:

渔网 (FN) 作为青粘合剂的结构增强剂,提高了灵活性和耐热性.
优化FN剂量和在现实条件下评估性能对于平衡刚性,弹性和耐用性至关重要.
这种方法为管理塑料废物,减少道路建设对环境的影响和二氧化碳排放提供了可持续的解决方案.

Sustainable Development

Sustainable Development

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
