Abstract

The invention discloses a gravity cylindrical electrostatic spinning device and method. The device includes a cylindrical spray head, and a cylindrical liquid supply device with a gap is arranged inside the cylindrical spray head. The cylindrical liquid supply device is connected to the solution propeller outside the cylindrical spray head through a hose, and the shell of the cylindrical spray head is connected to the high-pressure generator. device connection. The spinning method is: open the solution propeller, inject the solution into the cylindrical liquid supply device through the hose, and when the liquid level of the solution overflows the gap of the cylindrical liquid supply device and overflows, the gap between the cylindrical nozzle and the cylindrical liquid supply device Fill the spinning solution; turn on the high-voltage generator, apply a positive voltage to the cylindrical nozzle, and form a jet on the spinning surface. Under the action of the electric field force, the jet moves rapidly to the metal drum, and with the volatilization of the solvent, it finally deposits on the Metal tumbler surface. The invention controls the solution through the overflow liquid supply device, and generates charge accumulation on the edge of the gap on the cylindrical surface, so as to realize electrostatic spinning in the direction of gravity.

Description

technical field [0001] The invention relates to a gravitational cylindrical electrostatic spinning device and method, belonging to the technical field of electrostatic spinning and textile machinery. Background technique [0002] Electrospinning is one of the most effective ways to prepare nanofiber materials. Compared with the preparation techniques of nanomaterials such as stretching method, template synthesis method, and self-assembly, electrospinning has the advantages of simple operation, short preparation process, and wide selection of materials. advantage. Compared with traditional textile fiber materials, due to their extremely small scale, nanofibrous materials have many characteristics that are difficult to exhibit at large scales, such as obvious surface and interface effects, unique small size effects, large specific surface area and extremely large size. high porosity etc. Therefore, nanofiber materials have a wider range of applications, such as air filtratio...
