Description
Technical Field
The utility model relates to a jet-propelled electrostatic spinning equipment technical field, especially a jet-propelled even jet-propelled electrostatic spinning nozzle of even jet-propelled, the atmospheric pressure degree of consistency is good all around.
Background
Electrospinning is a special fiber manufacturing process, where polymer solutions or melts are jet spun in a strong electric field. Under the action of the electric field, the liquid drop at the needle head changes from a spherical shape to a conical shape (i.e. a Taylor cone) and extends from the tip of the cone to obtain a fiber filament. This way, polymer filaments of nanometer-scale diameter can be produced. The electrostatic spinning technology is to prepare various organic, inorganic and composite nano-fiber materials by utilizing polymer solution or melt to carry out jet spinning in a strong electric field. Under the action of a strong electric field, the adhesive substance at the electrospinning needle head changes from a spherical shape to a conical shape (taylor cone) and a fiber filament is obtained by extending from the tip of the cone. However, as most of the spinning solutions have high volatility of organic solvents, the needles are very easy to form adhesive substances during the spinning process, block the needles, affect the spinning effect and reduce the spinning efficiency.
In the prior art, in the air-jet electrostatic spinning process, two-way symmetrical structures are adopted for air supply, the application number is 201080035112.0, and the publication number CN102459719B discloses an injection nozzle for electrostatic spinning and electrostatic spinning equipment using the same. The electrospinning device mainly performs air electrospinning in which a source liquid for fiber is injected together with air and the source liquid for fiber is discharged through the nozzle member, and pure electrospinning without air injection can be effectively performed by separating the second nozzle body as follows: exposing a lower end of the nozzle member to a predetermined length or more. The scheme can realize uniform air injection in the transverse direction, but the air pressure is reduced in the longitudinal direction. The air jet spinning which is high in fine fiber and processing requirement is not applicable. The air-jet electrostatic spinning nozzle with uniform air injection around and good air pressure uniformity is needed.
