Description
Technical field
The present invention relates to a kind of electrostatic spinning apparatus, be specially a kind of many solid needles electrode nano fibre nonwoven production apparatus.
Background technology
Be meant on the nanofiber narrow sense that diameter is less than the following fiber of 100nm; Because its diameter is superfine; Make fiber specific surface area that qualitative leap take place, greatly improved its surface energy, thereby given its special small-size effect, skin effect, quantum size effect, macro quanta tunnel effect etc.; All show excellent specific property in properties such as physics (light, heat, electromagnetism etc.), chemistry, become the research focus of following 21st century.Nano-fiber for production of non-woven is with a wide range of applications at aspects such as environmental protection filtering material, nano combined reinforcing material, tissue engineering bracket, drug release carrier, photoelectric device, catalysis materials.
Electrostatic spinning is one of effective technology for preparing at present nano-fiber for production of non-woven; This technology was at first invented [A.FORMHALS.Process and apparatus for preparing artifical threads:USA in 1934 by American Formhals; 1975504 [P] 1934.]; Its core is that polymer solution or the melt under the effect of high-pressure electrostatic field force produces jetting stream, and the dynamic analysis of spinning of spurting " disturbing phenomenon " will take place in air splits into many finer fiber threads again, constantly attenuated; Solvent evaporates in the while thread (or the cooling of melt thread); The fiber solidified forming is collected device and accepts, and obtains nano-fiber for production of non-woven.Static spins that kind comprises that solution static spins and big type of melting electrostatic spinning two, and wherein solution static spins because its equipment and technology are simple and obtains fast development.
Solution electrostatic spinning machine or device mainly comprise spinning head, spinning solution feed system, high-voltage generator and fiber collecting plate four big major parts.It is spinning head that the conventional electrostatic spinning machine adopts monometallic capillary needle tubing, like Chinese patent 200420020596.3,200410025622.6; 200420107832.5 etc. disclosed technology; U.S. Pat 6753454, US6656394, disclosed technology such as US6713011.
Along with electro-spinning nano fibre nonwoven receives the industrial quarters pay attention to day by day, traditional single needle pipe electrostatic spinning machine can't satisfy the demand of large-scale application because productive rate is lower, has become its bottleneck problem that further develops of restriction.Improve the problem that electro spinning nano fiber output has become expert, scholar's common concern and faced.
On the basis of single needle electrostatic spinning device, many scholars have developed the spininess electrostatic spinning apparatus, and Theron etc. are with the multiple spray head static spinning machine [S.A.THERON of a plurality of metal needle tubings according to arranged in a straight line or arranged; A.L.YARIN, E.ZUSSMAN, E.KROLL.Multiple jets in electrospinning:experiment and modeling.Polymer; 2005,46 (9): 2889-2899.], a lot of similar patents have also appearred in the world; Like WO2005/073441 1, WO 2004/016839 A1, USA 6,382,526, USA; 6,616,435B2 etc.Improve although the spininess electrostatic spinning technique has had on output significantly, and can reduce the problems such as phase mutual interference between spininess through the position of reasonable Arrangement pin.But in thousands of syringe needle spinning processes, in case stopping up or the dropping liquid phenomenon appears in certain or a plurality of syringe needle, with the uniformity that has a strong impact on product, quality, and cleaning work is loaded down with trivial details, and influence is produced.
2004, started the beginning of needleless electrostatic spinning technique by the ELMARCO company of Czech in the swing roller electrostatic spinning technique that produces, and applied for patent (WO2005/024101 A1).This technological cardinal principle is the rotating metallic roll shaft (or being carved with different decorative patterns) that solution is immersed in the mounting portion in liquid storage tank; Spinning solution is along with the roll shaft surface is taken in the rotation of roll shaft to; Be applied with a high-pressure electrostatic in liquid storage tank or on the roll shaft, the spinning solution on electric field force effect lower roller shaft surface forms multiple jets, spreads all over the drum length direction; Thereby can obtain higher output; This equipment yield can reach 1～15g/min, and the about 100～1000nm of fibre diameter is for solid foundation has been established in the realization of goal of nanofiber suitability for industrialized production.Because this spinning spray silk zone is on the roll shaft surface, does not use traditional capillary metal needle tubing, so be referred to as the needleless electrostatic spinning machine.Compare with the pin type electrostatic spinning,, avoided the generation of drop, and had high yield because its fiber jet is directed upwardly.But this needleless roll shaft formula electrospinning device need be higher in spinning process than pin type spinning machine high-pressure electrostatic; Its starting resistor (voltage value when spinning solution forms taylor cone) is usually more than 40kV; Its reason is that the roll shaft surface curvature is bigger, and electric field is not concentrated in its surface distributed, and during the roll shaft rotation; Its surface band liquid measure is more, therefore needs higher voltage to overcome the surface tension of spinning solution and form taylor cone; In addition, the fibre diameter of roll shaft formula needle-less electro-spinning is thick than the pin type electrospinning fibre, generally more than 300nm, have in addition surpass 1 μ m; Moreover too high voltage value can cause puncturing, leaky, and is higher to apparatus insulated requirement, the corresponding increase of spinning energy consumption.But relating to needle-less roll shaft formula electrostatic spinning apparatus patent also has: Chinese patent 200410025622.6,200610036635.2,200710036447.4,200810032247.6 etc.
From the spinning technique angle, increase concentration of dope and also help to improve the output of electrostatic spinning nano fiber to a certain extent, and can reduce the solvent use amount, reduce production costs and environmental pollution.Yet spinning solution solubility is big more, and its viscosity is also big more, and the high concentration spinning solution is extruded difficulty in the capillary needle tubing, will speed up injector head and stops up; Cause difficulty in spinning in needleless roll shaft surface band hypervolia, even can't carry out electrostatic spinning.Up to now, rarely have electrostatic spinning apparatus document and the patent report that is suitable for the high concentration spinning solution.
