Abstract

The invention provides a method for drying a graphite nylon belt before extrusion, and relates to the technical field of graphite nylon belt processing. The method for drying the graphite nylon tape before extrusion comprises the following steps: S1, preparing a sufficient amount of graphite material and nylon material, and pre-drying the materials, S2, uniformly mixing graphite and nylon particles in a mixer according to a ratio, and S3, carrying out simple preliminary heating and preheating treatment on the mixture through a drying oven to help to remove surface moisture, so as to obtain the graphite nylon tape after extrusion. S4, proper microwave drying equipment is selected, the preheated mixture is evenly laid on a tray of the microwave drying equipment, and S5, the microwave frequency is set, the drying time is adjusted to be 5-10 minutes, the power is adjusted to be 300-700 W, the microwave drying equipment is started, and the drying effect is observed. By adopting a microwave drying technology and a gradient power mode, not only is the drying time shortened, but also the problem that the surface of the material is overheated due to overhigh power is solved, and the time and the energy consumption are remarkably reduced.
