First, the main purpose and scope ofapplication
Electrostatic spinning method (electrospinning) is akind of high pressure electric field, the polymer solution or melt spinninginto micron to nanometer scale.
Simple and effective processing technology of fiber,that is, polymer injection. Because the fiber is much thinner than thetraditional method, the diameter of the fiber is usually tens to thousands ofnanometers, and the fiber surface can form a lot of micro structure, which hasa strong adsorption capacity and good filtration, barrier property, thermalinsulation and so on. These special properties are similar to the structure ofwoven fabric made by electrospinning, and more close to the structure of theorganism. Therefore, it is especially suitable for biomedical applications suchas biological membranes, wound coating materials, hemostatic materials,artificial blood vessels, drug and gene delivery, tissue engineering scaffolds,etc..
Applications: biopolymer, general polymer, pre polynanometer fiber preparation; preparation of polymer blend nanofiber; with nanopores, nano particle, nano pearl on structure surface or film.

High-voltage power supply
Located in theright side of the box (see Figure 1).
Propulsion pump on the stepper motor (Y axis) in thecomputer control, through the screw drive, so that promote the rod forward, thesolution through the pump tube into the nozzle (when the spinning speed is veryslow, about 0.001 - 0.005mm/s, because the polymer solution in the nozzle ischanged into a "digestion process" is very slow, pushing too fast todigest, the solution is easy to drop off pollution samples). While the sampleor the replacement of the new solution, the need to promote the rapid retreat.Method is
Use "manual high speed reverse.

8 operating instructions
(1) temperature regulation in the box
Set the heating temperature, according tothe required temperature and the choice of the number of heating lamps (1/4open, half open, and so on). When the temperature is constant, the propulsioncan be turned on and the spinning operation is carried out.
(2) speed regulator
According to the instrument panel on the speedknob, according to the instrument panel on the direction of the knob, to theclockwise or counterclockwise rotation, adjustable speed.
(3) high voltage power supply
When the toggle high voltage DC powersupply panel from zero to + 50kV voltage knob, on the left side of the panel"voltage display", "current" box shows the current voltage,current value, this value for electrospun need to set the main parameters.
(4) open the electrostatic spinningapparatus control program, the program input, start the program, the view ofthe X, Y, after the cessation of exercise.
(5) close the toughened glass door, turn onthe high voltage DC power supply, open the electrospinning control program tocarry on the spinning. This machine has automatic protection device (the dooropen - door closed off electric power)
1 when the power spinning operation, it isforbidden to cut off the high voltage DC power supply and open the toughenedglass door, hand in hand contact with the metal wire and the metal aluminumfoil below, causing high voltage DC power to the human body. Does the jobbecause of electric spinning need and not cut off the high voltage DC powersupply, must with toggle insulator metal needle below aluminum thin.
2 electrical machinery work abnormal,should immediately turn off the high voltage DC power supply and checked by aprofessional and technical personnel, troubleshooting before the normal work ofelectric spinning.
3 0~+50kV voltage regulation, by the firstknob counterclockwise to the end (to the 0 position), and then clockwise toadjust to the required voltage.
4 electric spinning box at the top of thepropeller changing electro spinning solution, you must close the good highvoltage DC power supply.
5 when the high voltage DC power supply,press the "stop" button on the right side of the high voltage DCpower supply panel, press the "power" button on the high voltage DCpower supply, and turn off the high voltage DC power supply. When necessary,desirable under three-phase socket high voltage DC power supply and electricsocket on the right side in the middle of textile machinery.
Users in the correct use of the rules, fromthe use of 1 years, the electrostatic spinning machine for manufacturing qualityand can not work properly, the company free of charge for the user repair. 1years after the additional cost of the Buddha and the Buddha artificial.
