摘要

在过去的几十年里,环境污染已经成为一个必须解决的重大问题。由于填埋垃圾的过剩和随之而来的环境恶化,剩饭剩菜的处理已经引起了很大的担忧。正在审查的备选办法之一包括重新执行或重新处理垃圾,这可能既具有生态效益,又具有经济效益。蛋壳代表了一种非生产性垃圾,具有改变物质领域的巨大潜力。本实验采用鸡蛋壳制备环氧聚合物复合材料。通过改变蛋壳粉的体积(0、10、20、30、40和50 wt%),探索了六种形式的组合。进行物理(密度,空隙估计,热行为),机械和摩擦学评估。结果表明,在环氧介质中加入30%的蛋壳粉可以增强环氧树脂的力学性能。通过不考虑外力(10 N、20 N和30 N)的行程长度来探索所建立样品的摩擦学性能,结果表明,延长行程长度会导致更大的磨损和CoF,在最高载荷下,样品的增幅最大,达到50%。最后,粉末的整合使创造出具有改进的特殊属性和耐磨性的廉价物质成为可能,可用于在广泛的室内和室外用途中替代塑料和传统物质。

Evaluating the physical, mechanical, structural and tribological functionality of ecological composites constituted of bio-fillers extracted from eggshell residues

In the last couple of decades, environmental contamination has emerged as a significant concern that has to be addressed. The disposal of leftovers has generated substantial worries due to the emergence of surplus landfill trash and the ensuing rise in environmental degradation. One of the alternatives being examined includes the re-implementation or reprocessing of garbage, which might have both ecological and monetary advantages. Eggshells represent one of the unproductive garbage with enormous potential to alter the substance realm. Chicken eggshells are employed in the current experiment to establish epoxy polymeric composites. Six forms of combinations are explored by altering the volume of eggshell powder (0, 10, 20, 30, 40 and 50 wt%). Physical (density, void estimation, thermal behavior), mechanical and tribological assessment is performed. The outcomes illustrated that inserting up to 30 wt% proportions of eggshell powder to an epoxy medium strengthened the mechanical attributes. The tribological performance of the established samples are explored by accounting the travelling length regardless of applied forces (10 N, 20 N and 30 N) and revealed that extending the travelling length contributed to greater wear and CoF, with the most significant increase perceived for the samples at 50 wt% at the highest load. Finally, the integration of powder enabled the creation of inexpensive substances with improved particular attributes and wear durability that may be employed to substitute plastic and traditional substances in a wide range of indoor and outdoor uses.

期刊介绍: The Journal of Material Cycles and Waste Management has a twofold focus: research in technical, political, and environmental problems of material cycles and waste management; and information that contributes to the development of an interdisciplinary science of material cycles and waste management. Its aim is to develop solutions and prescriptions for material cycles. The journal publishes original articles, reviews, and invited papers from a wide range of disciplines related to material cycles and waste management. The journal is published in cooperation with the Japan Society of Material Cycles and Waste Management (JSMCWM) and the Korea Society of Waste Management (KSWM).
