Test Procedures / Working Principle
The unit uses electrospinning to form continuous polymer fibers under a high-voltage electric field. Polymer solution or melt is ejected from the positive electrode to the grounded collector, forming continuous nanofibers on the collector plate or drum. Fiber diameter, spinning speed, injection distance, and voltage are adjustable.
Operation Steps:
Set workspace temperature and humidity
Install injection pump(s) and drum collector
Configure pump speed, movement speed, and deposition distance
Activate high-voltage power supply
Observe fiber deposition and adjust parameters as necessary
After completion, turn off power and collect fibers
Maintenance Information
Clean injection pump and electrode capillary regularly to avoid clogging
Inspect drum collector and electrodes before each use
Ensure proper grounding and check insulation of high-voltage components
Keep workspace dry and free from condensation
Store unit in a dust-free environment when not in use
