The roller 3 is adjoining to 2, and the speed of 3 and 2 lines is the same but the direction is oppositely rotated due to friction between two rollers.
Description
Technical field
The utility model relates to a kind of device of continuous production nano fibrous membrane, adopts this device Polymer Solution can be made nano fibrous membrane continuously with method of electrostatic spinning.
Technical background
Number of patent application be 200480056915 and WO2005073441 in, a kind of continuous electrostatic spinning film forming apparatus has successfully been described.But lack description in these schemes to wrap-up.The utility model provides a kind of device that has the continuous production nano fibrous membrane of film take-up in order to overcome above-mentioned shortcoming.
The content of invention
The objective of the invention is provides a kind of electrostatic spinning film forming apparatus by the utility model, a kind ofly can produce the nano fibrous membrane industrialized unit continuously.This device comprises DC high-voltage power supply, liquid-supplying system, jet head sets, meets a system, the rolling system.DC high-voltage power supply is that a voltage adjustable range is the high pressure generator of 0-35000 volt; Liquid-supplying system is made up of the sebific duct of peristaltic pump and organic solvent-resistant; Jet head sets 4 is made up of some syringe needles; To meet a system and be a diameter be that 400-600mm is long is the cylinder of 800-1500mm, is referred to as to connect roll dies 1 and links to each other with a buncher; The rolling system is made up of two parts: the first is taken off the film guide roller 2 of holding concurrently near what connect roll dies 1, and roller 2 is diameters for the 100-200mm surface is surrounded by the cylinder of one deck rubber, length with connect the roll dies coupling, 2 and 1 distance can be by the pneumatic element adjusting that is contained on 2; Another part is that the distance of wind-up roll 3,3 and 2 is regulated by the pneumatic element that is contained on 3.
Description of drawings
The cross-sectional view that has schematically shown apparatus of the present invention in the accompanying drawing.Figure acceptance of the bid 1 is for connecing roll dies; 2 are wind-up roll for taking off hold concurrently guide roller 3 of film; 4 is jet head sets.
The specific embodiment
The continuous production nano fibrous membrane industrialized unit that adopts the utility model to provide prepares nano fibrous membrane with suitable Polymer Solution.Its process is also to claim electrospinning liquid to be sent to jet head sets 4 Polymer Solution with solution feed pump, is flowed out by shower nozzle again.When shower nozzle and connect between the roll dies 1 when forming high electric field, electrospinning liquid forms Taylor's cone on the shower nozzle top.Because effect of electric field, liquid flow split becomes some threads, flows to connect roll dies.The solvent evaporates macromolecular solid changes into fiber simultaneously, is connecing film forming on the roll dies.Control connects the roll dies rotating speed, makes the film of acceptance reach the thickness that needs.Film is peeled off from connecing roll dies, walked around guide roller 2 and reach wind-up roll 3.Simultaneously with roller 2 near connecing roll dies 1 because the friction between two rollers, make 2 identical with 1 linear velocity and direction is rotated on the contrary.Simultaneously also with roller 3 near 2 because the friction between two rollers, make 3 identical with 2 linear velocities and direction is rotated on the contrary, with the film rolling.Roller 2 is constantly peeled off film from roller 1, send roller 3 to, forms continuously to produce.When the film of rolling reaches some, regulate pneumatic element roller 3 and roller 2 are left, change new wind-up roll, continue rolling near roller 2 again.
Example
Kynoar (PVDF) with the 3F company trade mark 904 is the electrospinning material, is solvent with dimethyl formamide (DMF), and acetone is conditioning agent.With DMF and acetone is mixed solvent, and preparation PVDF content is the electrospinning liquid of 8-10%.The film forming apparatus that adopts the utility model to provide is prepared nano fibrous membrane.Electrospinning liquid is delivered to jet head sets 4 with pump, flows out, under electric field action, carry out electrostatic spinning system film through shower nozzle.The high-pressure side of DC high-voltage power supply links to each other with jet head sets 4, and other end ground connection connects roll dies 1 simultaneously and also links to each other with the ground end.Regulate high pressure output at 20000～35000 volts, shower nozzle is about 180mm with connecing the roll dies spacing, and the electrospinning temperature is controlled at 30～40 ℃.Obtain the fiber of diameter, form non-weaving cloth connecing on the roll dies 1, be called nano fibrous membrane at 40～1000nm.Regulate the rotating speed of wind-up roll, can obtain the nano fibrous membrane of 10～100 μ m different-thickness.Film is peeled off from connecing roll dies, walked around guide roller 2 and reach wind-up roll 3.Film is constantly peeled off from connecing on the roll dies, and rolling is on wind-up roll continuously.
Industrial applicibility
The device of the continuous production nano fibrous membrane that the utility model provides is suitable for producing continuously various types of nano fibrous membranes.
