【摘要】：电力学崩解法是一种新型环保、高效、零混染的样品分离技术。该方法借助高频率变化的高压电场,在固体内部诱导形成电场畸变,进而在强畸变域内形成电场破坏,催生毛细管状放电网络,最终导致等离子体通道的急剧膨胀,产生张性破裂,实现矿物相之间的分离。相较于传统机械碎样法,该方法具有无尘环保、杜绝混染,微损耗、高回收,最大程度保留目标对象的粒度和形貌特征,以及低能耗的优势。目前该设备在地学及其相关领域已初步应用于珍贵样品的单矿物分离、矿物材料特性的改善、特殊材料的回收利用,以及古生物样品的完整提取等方面,更多的应用尚待开发。
[Abstract]:Electrical disintegrating method is a new environmental-friendly, high-efficiency, zero-mixed sample separation technology.With the help of high frequency high voltage electric field, the electric field distortion is induced in the solid, and then the electric field is destroyed in the strong distortion region, resulting in the capillary discharge network, which eventually leads to the rapid expansion of the plasma channel.Tensile rupture is produced to separate mineral phases.Compared with the traditional mechanical shredding method, this method has the advantages of dust-free environmental protection, elimination of mixed dyeing, micro-loss, high recovery, maximum retention of the granularity and morphology of the target object, and the advantages of low energy consumption.At present, the equipment has been applied in the fields of geoscience and its related fields, such as the separation of precious samples, the improvement of the characteristics of mineral materials, the recovery and utilization of special materials, and the complete extraction of paleontological samples.
