Working Principle

When a polymer solution or melt is extruded from the spinneret, surface tension tends to form it into spherical droplets. A high voltage applied to the spinneret charges the surface of the droplets with the same polarity. When the electrostatic repulsion is strong enough to counteract the surface tension, the droplets form a conical shape (Taylor cone). As the voltage increases, the polymer droplets are gradually stretched. When the charge repulsion exceeds the surface tension, the polymer droplets form a jet that ejects from the surface of the Taylor cone. Simultaneously, the solvent evaporates or solidifies, eventually landing on the collection device to form nanofiber mats, webs, or membranes.

Structural Components

- High-voltage power supply: Provides the necessary high voltage for the spinning process, charging the polymer solution or melt. The voltage typically ranges between 1-30 kV.

- Injection device: Usually consists of a syringe, needle, and injection system. Common configurations include single-needle devices, but multi-needle nozzle devices can also be configured to increase production.

- Collection device: Comes in various forms, including flat plate collectors, drum collectors, cage collectors, and disc collectors. These are used to collect nanofibers, and by altering their geometric dimensions and shapes, the alignment of nanofibers can be adjusted.

Model Example

Taking the ZYPM-M52 standard experimental electrospinning machine as an example, its dimensions are 600mm (length) * 800mm (width) * 1700mm (height). It can be used to prepare ultrafine fibers with diameters ranging from 50-200 nm, suitable for verifying the spinnability of solutions and exploring material spinning parameters. It can produce non-woven fabric samples the size of A4 paper.

ZYPM-M52 Standard Experimental Electrospinning Tester Electrospinning is a special fiber manufacturing process in which polymer solution or melt is sprayed and spun in a strong electric field. Under the action of the electric field, the droplet at the needle tip changes from a sphere to a cone (Taylor cone), and extends at the tip of the cone to obtain fiber filaments. This method can produce polymer filaments with nanometer diameters.

Suitable for verifying the spinning possibility of solutions, exploring material spinning performance parameters, and producing A4-sized non-woven fabric samples.
