Patent no. RO File 9020/3.06.2010
The present innovation develop a technology for nanofiber
production by means of a computer controlled
electrospinning system developed based on the idea of
modularity and computerized control. According to the
invention, nanofibers achievement through electrospinning
computerized system is innovative by specific
Description
technologies software and by the features of computerized
control equipment which allow us to command and
control the following parameters: high voltage in two
ways: at constant tension and constant current, the flow of
polymer solution, the control volume of polymer solution
into the syringe, in use, the speed of the nozzle, wide
nozzle movement, speed of rotation of the collector, for a
cylindrical collector, speed of movement of the collector,
for other types of collectors, the temperature of the air, the
humidity of the air, the air speed that process occurs, the
distance between the nozzle and the collector, the value of
electric current that flows through the nanofiber, the
electric field distribution along the nanofibre, speed nozzle
cleaning needle tip in the operation.
