Description
Technical field
The present invention relates to a kind of New type of current mechanics method, effect and the spinneret-free of particularly initial jet circle of machined material being located power-assisted combine with electric fluid mechanics method, can be with cheap cost, on a large scale material is processed.This method is adapted to electrostatic spray, electrostatic spinning, electrostatic spraying.
Background technology
Thereby electric fluid mechanics method refers to machined material and utilizes electrostatic force and balanced inside motive force and break through the surface tension of processed fluid attitude material and internal action power and form in the mode of jet and be dispersed in other fluid attitude medium that can not mix fully mutually with small fluid attitude material form and curing forms the method that comprises particle, fiber under charged situation, comprise electrostatic spray method, electrostatic spray and method of electrostatic spinning, estimated current mechanics method is all undertaken by spinning head the processing of material.Electric fluid mechanics method can obtain the refinement material with cheap price, convenience and position-controllable ground owing to introduced electrostatic force, and therefore electrostatic spray and Electrostatic Spray Technology have been widely used in industrial and agricultural production, the life at present.And electrostatic spinning is because the low development that also is at present of its production capacity.
Yet estimated current mechanics method is still waiting further to improve and improves to adapt to the needs that people obtain super-fine material and production capacity raising.This is then can reduce cost owing to super-fine material has very big superior performance production capacity raising.Yet current electric fluid mechanics method utilizes electrostatic force and accurate balanced inside motive force (pressure that promptly is applied on the machined material is identical except that edge effect) often to be difficult to satisfy these needs of people merely.People find that in the Electrofluid Mechanics process size of the high more material that obtains of voltage that machined material is applied is big more, if and apply lower voltage, electrostatic force and accurate balanced inside motive force are difficult to break through the interfacial tension and the material internal active force of material again, particularly for the higher material of viscosity, very big as the raw materials used often viscosity of electrostatic spinning, thus simple pass through pressure advance machined material to flow and apply its processing that is obtained of high voltage after material the instrument size is big and the big production capacity of difficulty of processing is extremely low.
But not being used for the initial jet boundary of machined material place, the proportionality action masterpiece then can solve the existing problem of estimated current mechanics method effectively.In fact people have successfully introduced still incognizant lack of balance active force in hydrodynamic methods.When for example people utilize flash distillation, a large amount of bubble growths, fragmentation are arranged in the liquid, thereby produce the lack of balance active force and the effect of improving atomizing effect is introduced into the spraying field.At present, flash evaporation technology successfully has been applied to nonwoven and generator fuel nozzle field.Similarly, people are applied to the spraying field with ultrasonic wave can produce the lack of balance active force in liquid material characteristics, have also obtained good effect.Aspect electric fluid mechanics method, people have improved the electron spray effect by introducing air-flow, but owing to do not recognize its mechanism of action, present gas helps the designed air-flow of electron spray still to fail to make full use of the lack of balance active force that air-flow produces aspect flow velocity, the streamer mode comprising, therefore still can further improve, improve.It is to realize raising to the electron spray effect by the faint negative pressure of lack of balance around nozzle that non-rotating air-flow produces that present gas helps electron spray, if change secondary air into swirling eddy then be expected to improve negative pressure and further improve the electron spray effect.So the lack of balance active force is introduced effect that electric fluid mechanics method is expected to improve prior art, is reduced cost.
In addition on the one hand, therefore present electric fluid mechanics method does not still have the electric fluid mechanics method of spinneret-free at present owing to be difficult to process machined material by simple electrostatic force and inner accurate balanced thrust.If but can adopt electrofluid mechanics method without spinning jet not only can save the manufacturing of costly complicated spinning head and maintenance cost but also can process on a large scale, produce.For this reason, the present invention combines the formation assistance type spinneret-free electrofluid mechanics method with lack of balance active force and spinneret-free with electric fluid mechanics method, and this method is adapted to electrostatic spray, electrostatic spraying and electrostatic spinning.
