Graphene sheet paint spraying and drying device

Abstract

The invention discloses a graphene sheet paint spraying and drying device which comprises a sliding rail, a placement table, paint spraying racks and vacuum chucks. A telescopic supporting rod is installed inside a slide of the sliding rail; the upper end of the telescopic supporting rod is fixedly connected with the bottom center portion of the placement table; drying openings of an inverted-circular truncated cone structure are formed in the placement table in an evenly penetrating mode; first hot air pipes communicating with the drying openings are arranged on the lower portion of the placement table; a graphene sheet is arranged on the placement table; the paint spraying racks are symmetrically arranged on the two sides of the placement table; an upper paint spraying nozzle, a middle paint spraying nozzle and a lower paint spraying nozzle are arranged on each paint spraying rack at intervals from top to bottom; and the upper paint spraying nozzles align with the upper side face of the graphene sheet. The graphene sheet paint spraying and drying device integrates paint spraying and drying, paint spraying and drying can be completed in one procedure, the production machining efficiency of the graphene sheet is improved, dead corners of paint spraying are avoided, and the situation that a paint face is destroyed to cause flaws after paint spraying is prevented.

Description

technical field [0001] The invention relates to the field of production and processing of graphene plates, in particular to a paint spraying and drying device for graphene plates. Background technique [0002] Graphene is a two-dimensional crystal made of carbon atoms with only one atomic thickness. In 2004, Andre Geim and Konstantin Novoselov, physicists at the University of Manchester, successfully separated graphene from graphite and confirmed that it can exist alone. Bell Prize in Physics. Before the discovery of borophene in 2015, graphene was both the thinnest material and the strongest, with a fracture strength 200 times higher than the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is currently the thinnest and strongest material in nature. If a piece of graphene with an area of ​​1 square meter is used to make a hammock, it can bear a cat weighing one kilogram with a weight of less than one milligr...

Problems solved by technology

The general drying method is to clamp the board for drying. In this drying method, it is difficult to spray paint on the board at the clamping place, and if one side of the board is painted and turned over to spray paint on the other side, it is easy to cause the painted surface to be damaged. damage, forming defects, and then affecting the production quality of the entire plate
