Abstract

The current study reviews the viability of various fibre-polymer composites and treatment techniques along with the intricacy involved in improving the rotational moulding process. It is a method used in the manufacturing of hollow plastic items free from stress. As the rotational moulding process has gained prominence in a variety of crucial applications in recent years, a detailed analysis of this technique is important. For this reason, an exhaustive review of various fibres and polymers used in rotational moulding along with different pre-treatment techniques for improving the processability has been carried out and categorised into three sections. The first section deals with the type of polymers which are used for the process along with their nature and suitability for rotational moulding. The second section deals with the study of different fibres that have been blended with the polymers. The last section of the review discusses the different fibre treatment techniques which can be used to improve polymer-fibre compatibility. From a wide range of polymers used, it has been observed that the ease of processability of linear low-density polyethylene makes it the most suitable grade for rotational moulding. It can also be noticed that artificial fibres provide good mechanical properties compared to natural fibres but being eco-friendly and having low cost, natural fibres are more vital in the application. It is evident from the review that fibre pre-treatment enhances the polymer-fibre compatibility which improves the mechanical properties of the rotationally moulded products. Further, it can be concluded from the literature review that an adequate variety of polymer and fibre along with fibre treatment techniques can make an important contribution to the rotational moulding process.

聚合物、纤维添加剂和纤维处理技术在旋转模塑加工中的应用综述

目前的研究综述了各种纤维-聚合物复合材料的可行性和处理技术，以及改进旋转成型工艺的复杂性。这是一种用于制造无应力中空塑料制品的方法。近年来，随着旋转成型工艺在各种关键应用中的突出地位，对该技术的详细分析非常重要。因此，我们对用于旋转成型的各种纤维和聚合物以及用于提高可加工性的不同预处理技术进行了详尽的综述，并将其分为三部分。第一节介绍了用于该工艺的聚合物类型，以及它们的性质和旋转成型的适用性。第二部分介绍了与聚合物共混的不同纤维的研究。综述的最后一节讨论了可用于改善聚合物纤维相容性的不同纤维处理技术。从广泛使用的聚合物中，已经观察到线性低密度聚乙烯的易加工性使其成为最适合旋转成型的等级。还可以注意到，与天然纤维相比，人造纤维提供了良好的机械性能，但由于环保和成本低，天然纤维在应用中更为重要。从综述中可以明显看出，纤维预处理增强了聚合物纤维的相容性，从而提高了旋转成型产品的机械性能。此外，从文献综述中可以得出结论，适当种类的聚合物和纤维以及纤维处理技术可以对旋转成型过程做出重要贡献。

期刊介绍： Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
