Detailed description of the invention
The invention discloses a kind of device for spinning of high efficiency high quality of production nanofiber, in order to solve nanofiber diameter plucked in conventional batch spinning process, can the limited technical problem of spinning polymer kind, concrete, this electrostatic spinning apparatus is by adopting with the disk of needle point or woven wire disk as spinning appts, the generation of polymer electrified jet is process initiatively, the process of this active overcomes needleless electrostatic spinning instability in the past, uncontrollable shortcoming, make the carrying out that spinning process is easy and stable, solving conventional batch production process can the limited shortcoming of spinning polymer kind.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be described in detail the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
As shown in Figure 1, a kind of electrostatic spinning apparatus, it spinning appts 3 comprising dash receiver 1, the high-voltage DC power supply 2 be connected with dash receiver 1, solution tank 4 in order to storage polymer solution, motor 5 and be connected with motor 5.
As shown in Figures 2 and 3, spinning appts 3 adopts rosette 31 with some needle points or woven wire disk 32, rosette 31 or woven wire disk 32 are placed on solution tank 4, and after needing to ensure that rosette 31 or woven wire disk 32 are placed in solution tank 4, needle point is had to touch polymer solution, rosette 3 or woven wire disk 32 are provided with rotating shaft, and described electrostatic spinning apparatus comprises the connector connecting motor 5 and rotating shaft.So by rotating, the needle point with polymer solution forward to just to dash receiver 1 local time, better generation polymer jet initiatively.With rosette 31 and the woven wire disk 32 of needle point, can generation polymer jet initiatively, make spinning process controlled, carry out smoothly.
In technical solution of the present invention, the equidistant arrangement of needle point, and diameter, length and quantity can according to practical adjustments.Motor 5 rotating speed can regulate according to actual conditions.
Disk described in present specification all refers to rosette 3 or woven wire disk 6, because technical characterstic is identical, is described so not separated.Needle point can singlely be arranged, and namely some described needle points are installed on disc surfaces and form a circle, and some described needle points can adopt equidistant arrangement, so can ensure the uniformity of nanofiber.Certainly, needle point also can adopt array arrangement, and namely the needle point of some described array arrangements is installed on disc surfaces and forms multi-turn, and the needle point in each circle can equidistantly be arranged, and can equidistantly arrange between two adjacent rings.So can ensure the uniformity of nanofiber.
As shown in Figures 4 and 5, Fig. 4 and Fig. 5 is the schematic diagram of two kinds of receiving systems 1 respectively, and in Fig. 4, receiving system 1 is that in metallic plate 11, Fig. 5, receiving system 1 is cylinder 12.
In Fig. 1 of the present invention, although receiving system 1 employing is metallic plate 11, what spinning appts 3 adopted is rosette 31, for Fig. 1, is all general references, so there is not the situation of indistinctive mark Chu.
In the inventive solutions, described in every root, needle point has identical length and diameter.So ensure that the homogeneity of nanofiber.
For the present invention, compared with spinning with traditional needleless, the needle point that every root is coated with spinning solution is just equivalent to a jet, and the generation of polymer jet is process initiatively.Therefore, spinning process is controlled.
Electric-field intensity concentrates on needle surface, and compared with spinning with traditional needle-free, the micron even spinning solution of Nano grade thickness cover needle surface, and under same condition, spinning needs lower voltage, also can obtain the less nanofiber of diameter.
The present invention, by adopting with the disk of needle point or woven wire disk as spinning appts, can improve the output preparing nanofiber, and can ensure the quality of nanofiber.The size of disk can change, and the length of needle point and diameter can change.
The operation principle of electrostatic spinning apparatus of the present invention (is described with metal dish 31, woven wire disk 6 is identical with it): the solution in solution tank 4 has certain viscosity, rosette 31 with needle point sways under the drive of motor 5, when solution tank 4, metal needle point is stained with the solution of thin layer, high-voltage DC power supply 2 positive pole is connected with motor 5 rotating shaft, negative pole is connected with dash receiver 1, electric field is formed like this between metal dish needle point and dash receiver 1, when voltage reaches certain critical value, the electrified jet of polymer one by one that needle point is formed, jet is through swinging, solvent evaporates, solidification process, be ejected on dash receiver 1, form nanofiber, motor 5 constantly rotates, band needle point metal dish 3 needle point is constantly coated with polymer solution, so just constantly produce nanofiber, and keep the quality of nanofiber.
Beneficial effect of the present invention totally comprises: adopt with the disk of needle point or woven wire disk as spinning appts, the generation of polymer electrified jet is process initiatively.The process of this active overcomes needleless Static Spinning instability, uncontrollable shortcoming in the past, make the carrying out that spinning process is easy and stable, can spinning as traditional single needle electrostatic spinning, under identical conditions, as long as traditional single needle electrostatic spinning technique can spin, this device can spinning, and like this, just solving conventional batch production process can the limited shortcoming of spinning polymer kind; Meanwhile, on electric-field intensity needle point concentrated, dish, the pin of equal length and diameter makes the nanofiber diameter prepared be evenly distributed.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.
