摩擦电效应在于某些材料与其他材料接触后带电。这一效应可以与电场力结合使用，以静电分离具有相似尺寸、密度、磁性和导电性的正负摩擦带电颗粒。摩擦-静电分离虽然已经使用了很长时间，但它的大规模应用受到许多需要解决的技术问题的阻碍：对环境条件的敏感性、材料电荷的不均匀、混沌的粒子轨迹、电极堵塞等。本文综述了近年来各种专利，这些专利声称这些问题都得到了创新的解决方案，从而提高了分离的效率和稳定性。改进涉及到该过程的每个阶段：(I)前处理和进料；(Ii)待分离材料的摩擦带电；(Iii)静电分离和颗粒收集。大多数新的应用是为了从工业废物中回收塑料和从飞灰中回收未燃烧的碳。文章最后对摩擦-静电分离领域的未来发展作了展望。
The tribo-electric effect consists in the electrification of certain materials after coming into contact with other materials. This effect may be used in conjunction with the electric field forces for electrostatically separating positively- and negatively-tribo-charged granules that have otherwise similar size, density, magnetic properties and electric conduc- tivities. Although tribo-electrostatic separation has been used for a long time, its larger-scale application is hampered by a multitude of technical problems that need to be solved: sensitivity to environmental conditions, non-homogeneity of mate- rial charging, chaotic particle trajectories, electrode clogging, etc. This paper reviews various recent patents that claim in- novative solutions of these problems, allowing increasing efficiency and robustness of the separation. The improvements concern each phase of the process: (i) pretreatment and feeding; (ii) tribo-charging of the materials to be separated; (iii) electrostatic separation and particle collection. Most of the new applications were developed for the recycling of plastics from industrial waste and the recovery of unburned carbon from fly ash. The paper concludes with a description of the fu- ture developments expected in the field of tribo-electrostatic separation.
