Detailed description of the invention
Use the electrostatic spinning film forming apparatus of the present invention, prepare nano fibrous membrane with suitable macromolecular solution.
Its solution can be aqueous solution, it is also possible to is organic solvent solution.Its process is that macromolecular solution is also referred to as electrospinning
Liquid flows to shower nozzle from hopper, then is flowed out by shower nozzle.High electricity is formed between shower nozzle and film-forming system circle steel band
During field, electrospinning liquid forms Taylor cone on shower nozzle top.Due to the effect of electric field, liquid flow split become some carefully
Stream, flows to circular steel band.The polymeric hardener of solvent volatilization simultaneously, forms nanofiber on circular steel band 5.
The most each row's jet head sets is with the most at the uniform velocity back and forth movement, and circular steel band 5 also rotates with certain speed, makes nanometer
Fiber forms uniform nano fibrous membrane.The kinetic control system of reciprocating screw rod or motor motor control system
Tracking joint jet head sets back and forth movement speed, matches with circular steel band 5 velocity of rotation each two-way time, and one
As control in the 2-3 second.Circular steel band 5 velocity of rotation regulates according to thickness requirement, when jet head sets comes and goes
When movement velocity is not mated, easily cause film forming uneven.Nano fibrous membrane is peeled off from circular steel band 5, by
The continuous rolling of wind-up roll 2.
Before carrying out electrostatic spinning masking program, thermostatic chamber 1 is heated.The span of control of temperature should be by
Dicyandiamide solution and the electrostatic spinning electric field intensity of electrostatic spinning liquid determine.If nanofiber of controlling well exists
Before circular steel band film forming, solvent volatilizees, and film forming has fine porosity and breathability.If controlling solvent well
Major part volatilization, but still have suitable small part, do not affect fibre deformation, at this moment due to fiber intersection points
Tight connection, the film of formation has the reticular membrane of high intensity.
