Diseño y construcción de una máquina de electrohilado vertical de 0 a 15 KV para generar nanofibras a base del polímero polisiloxano

Abstract

In the present technical project which is focused on the design and construction of a vertical electrospinning machine, using a high voltage source, which generates from 0 to 15 kV to generate nanofibers based on the polysiloxane polymer. To perform this machine, it was verified that the selection of the high voltage source is correct so that the polymer reacts and generates the nanofiber, so that the best option of the source that has a range of 0 to 15 kV has been obtained, proceeding then to the most appropriate selection of table movement that will be the base where the nanofiber falls and is deposited, using as an air drive and a single acting piston, which are electronically actuated by a 5/3 solenoid valve, which allows me to control the piston stroke more easily by positioning where the user needs the table to be. For the polymer injection system, the same principle of the table was used, which when activated with active air a piston that presses a syringe which sends the liquid polymer through a hose, reaching a needle and thus proceeded to make the nanofiber. Finally, with the nanofiber already obtained, we proceeded to review the diameter of the thread that has been generated, this will be thanks to the scanning microscope that has the Faculty of Civil and Mechanical Engineering of the Technical University of Ambato, observing an approximate diameter of 0,73 μm, obtained with a voltage of 13 kV and 10 cm distance, demonstrating that the machine generates fibers according to its parameters used.
