Nano-graphite sol preparation device and method

Abstract

The invention relates to the field of nano-graphite sol preparation and discloses a nano-graphite sol preparation device. The device comprises an electrolytic cell, flushing pipes and limiting cover plates, wherein the electrolytic cell comprises a cell body, a plurality of graphite supports are arranged at intervals in the width direction of the cell body, a plurality of groups of one-to-one corresponding support opening grooves are formed between every two adjacent graphite supports, a graphite plate is arranged between every group of support opening grooves, and one pair of diagonal cornersof each graphite plate are supported in the corresponding group of support opening grooves; the limiting cover plates are strip-shaped, a plurality of clamping grooves are formed in bottom surfaces of the limiting cover plates at intervals in the length direction, the limiting cover plates are arranged above the graphite plates, and the graphite plates are separated by the clamping grooves one byone; the flushing pipes are arranged along inner side walls of the cell body and extend along the bottom surface of the cell body. The invention further discloses a preparation method. The problem that the nano-graphite sol is easy to agglomerate in the preparation process can be solved, and the nano-graphite sol consumes short time during preparation and has few impurity ions, small particle size, high concentration and good stability.

Description

technical field [0001] The invention relates to the technical field of nano-graphite sol preparation, in particular to a nano-graphite sol preparation device and a preparation method. Background technique [0002] The preparation and application technology of nanomaterials has become a new content of material research in the 21st century. A large number of studies have shown that when carbon is in the nanoscale range, it has many special properties that conventional size carbon materials do not have. It is widely used in electric heating materials, battery manufacturing, magnetic recording materials, agriculture, aviation, aerospace and other fields. It has a wide range of uses and is a bright spot in the research of nanomaterials. However, since carbon is an element in a semi-metallic state, it has strong selective adsorption in the nano state and is negatively charged, so it is easy to agglomerate, making the manufacture of nano carbon very difficult. [0003] In the exi...
