Electrospinning machine & electrospray machine introduction

  • NM1 is a professional electrospinning machine independently developed by Nanofiberlabs. This equipment has the characteristics of small size and space-saving, which is particularly suitable for R&D and has a high degree of functional integration, which can meet the needs of electrospinning experiments.
  • Electrospinning technology is a simple and efficient nanofiber preparation technology, its principle is: in the high voltage electrostatic field when the electric field force is greater than the surface tension, the charged polymer solution will be sprayed into filaments, drawn, and refined under the action of electric field force, accompanied by solvent volatilization, and then solidified into nanofibers with a diameter of 50-300nm.
  • The nanofiber electrospinning device can produce ultra-fine nanofibers. The basic electrospinning solutions include PVA, PCL, TPU, PEO, PMMA, PVDF, PVP, etc. Inorganic additives: Titanium dioxide, silicon dioxide, etc. Natural product: Cellulose, sodium alginate, chitosan, collagen, etc.

The principle of the electrospray unit is to use the principle of corona discharge to make the atomized paint negatively charged under the action of a high-voltage direct current electric field and adsorb to the positively charged workpiece. The processed coating has a uniform thickness, strong adhesion, and no flow phenomenon that is common in the material spraying process. Compared with the electrospinning process, the electrospray coating requires a lower viscosity solution and a higher voltage.
