Tianjin Yunfan melt electrospinning machine high-temperature melt pressure extrusion

The Yunfan melt electrospinning machine adopts an industrial grade control system with high precision and stability.

When high-pressure melt spinning, the polymer is first heated to a certain viscosity of melt, and the nozzle is continuously and uniformly extruded using air pressure to form a fine stream. The fine stream is further stretched into finer fiber filaments under the traction of static electricity, cooled and solidified into nanofibers during the stretching process, and collected at the receiver. Melt electrospinning is not suitable for solvents and is not affected by solvent evaporation and toxicity.

Compared with solution electrospinning, melt electrospinning has the following advantages: 1 No need to use solvents: economical (saving solvent costs); Safety (no need to worry about fires caused by solvents); Environmental protection (solvent-free pollution to the environment); Efficient (high fiber purity, no solvent residue). two Some extremely insoluble polymers can also be electrospun into nanofibers. three The spinning process has small fiber whip movement and strong controllability of fiber deposition.
