Interrupted type centrifugal melting body electrostatic spinning device

Abstract

The invention discloses an interrupted type centrifugal melting body electrostatic spinning device and belongs to the field of electrostatic spinning. The interrupted type centrifugal melting body electrostatic spinning device mainly comprises a flinging disc, a receiving ring, a base and a temperature control system. The device can feed in an interrupted mode and can be used for experimental study. A recessed portion in the center of the flinging disc is a feeding vessel. A section of the flinging disc is thin in the middle and sharp at two ends. A pinhole nozzle is located in the horizontal center line portion of a wall of the flinging disc. The flinging disc is connected with high voltage electricity through a cage type support. The receiving ring is connected with the ground. The flinging disc is driven by a motor to rotate and fling a spinning melting body on the circumference of the flinging disc. The spinning melting body is attached to an outer wall of the flinging disc through the pinhole nozzle at the circumference and a large amount of small liquid drops are formed and are jetted under the action of electric field force so that threads are formed. According to the interrupted type centrifugal melting body electrostatic spinning device, electrostatic spinning fiber is ultrafine under combined action of the electric field force and centrifugal force and spinning efficiency is improved.

Description

technical field [0001] The invention relates to a centrifugal electrostatic spinning device, which belongs to the field of electrostatic spinning. Background technique [0002] As an important method for directly preparing nanofibers, electrospinning has the advantages of simple equipment and easy operation. Therefore, electrospinning technology has attracted widespread attention from scholars from all over the world. At present, researchers from all over the world have conducted a lot of research and exploration on electrospinning, and more than 100 kinds of polymers have been spun by electrospinning. [0003] However, there are many shortcomings in the current electrospinning device. The more common electrospinning device uses a single needle, and the productivity of the single-needle electrospinning device is only 0.1-1 g / h. The production cost is high, and it is difficult to realize industrialization and scale; The jets of the multi-needle electrospinning machine repel ...

[0003] However, there are many shortcomings in the current electrospinning device. The more common electrospinning device uses a single needle, and the productivity of the single-needle electrospinning device is only 0.1-1 g / h. The production cost is high, and it is difficult to realize industrialization and scale; The jets of the multi-needle electrospinning machine repel each other due to electrostatic interaction, so that the needles are blocked and the spinning quality is low
