Body mechanics processing. The method is suitable for use as a separation, protection, antibacterial, deodorant, catalytic, sensing, decorative, structural support, biocompatible, storage, controlled release, conductive, repair, medical, healthcare, smart response, aroma, adhesive function A method of preparing an ultrafine material or a coating method of a material that is one or more than one function. The prepared ultrafine material is applied in the form of particles, fibers, films, blocks or blocks. Background technique

The electrohydrodynamics method refers to the surface tension and internal force of the material to be processed by the electrostatic force and the quasi-equilibrium internal driving force under the condition of being charged to form a tiny flow by jet. The method of dispersing a body substance in other fluid medium which cannot be completely mixed and solidified into a method including particles and fibers, including an electrostatic spray method, an electrostatic spray method and an electrospinning method, and current electromechanical method for processing a material Both are carried out through a spinneret. The electrohydrodynamic method has been able to obtain refining materials at a low price, conveniently and in a positionally controllable manner due to the introduction of electrostatic force. Therefore, electrostatic spraying and electrostatic spraying techniques have been widely used in industrial and agricultural production and life. Electrospinning is still in the research and development stage due to its low production capacity.

However, the current electrohydrodynamics method needs to be further improved and improved to meet the needs of people to obtain ultra-fine materials and increase production capacity. This is because ultra-fine materials have great performance and increased productivity can reduce costs. However, current electrohydrodynamic methods simply use electrostatic forces and quasi-equilibrium internal propulsion (ie, the pressure applied to the material being processed is the same except for the edge effect), which often fails to meet these needs. In the process of electrohydrodynamic machining, it is found that the higher the voltage applied to the material to be processed, the larger the size of the material obtained, and if a lower voltage is applied, the electrostatic force and the quasi-equilibrium internal driving force are difficult to break through the material. The interfacial tension and the internal force of the material, especially for materials with higher viscosity, such as those used in electrospinning, tend to be very viscous. The purely pressure-propelled material flows and applies a high voltage to obtain the processed material. The size is large and the processing is difficult and the productivity is extremely low.

The non-equilibrium force acts on the initial jet interface of the material to be processed, which can effectively solve the problems existing in current electrohydrodynamics methods. The unbalanced force is fluidized due to the inconsistent size and direction of the applied force at the jet interface, resulting in a large force at some of the interfaces. The material to be processed has a partial preferentially protruding jet interface, which can help the fluidized material to break through the surface tension and internal force and is more likely to form a jet. For the charged jet, the auxiliary fluidization of the fluidized material produced by the unbalanced force is matched with the tip effect of the electrostatic field, so the auxiliary effect on the charged jet is more obvious.

In fact, people have successfully introduced unbalanced forces that have not been realized in fluid mechanics methods. For example, when people use flashing, a large amount of bubbles in the liquid grow and break, and the effect of unbalanced force to improve the atomization effect is introduced into the spray field. At present, flash technology has been successfully applied in the field of non-woven fabrics and generator fuel nozzles. Similarly, the application of ultrasonic waves to produce a non-equilibrium force in liquid materials has been applied to the field of spraying, and good results have also been achieved. In terms of electrohydrodynamics methods, people have improved the electrospray effect by introducing airflow, but due to the lack of awareness of its mechanism of action, current gas-assisted electrospray designs have not yet fully utilized airflow in terms of flow rate and airflow. The resulting non-equilibrium force can be further improved and improved. Therefore, the introduction of non-equilibrium force into the electrohydrodynamics method is expected to improve the effects of the prior art and reduce costs.

On the other hand, the current electrohydrodynamics method is difficult to process the material to be processed by simple electrostatic force and internal quasi-equalizing thrust, and the use of a non-spinning head electromechanical method can save costly complicated spinning. The manufacturing and maintenance costs of the head can be processed and produced on a large scale. However, there are only a few current electromechanical methods without a spinneret. The only example is the use of a vertical directional magnetic field on the free surface disturbance effect of the magnetic fluid to form a sharp needle-like protrusion perpendicular to the surface layer and electrohydrodynamics. The method combines to form a new method of electrospinning without spinneret. However, this method has only a small amount of ultrafine fibers because of its small assisting effect. To this end, the present invention combines other non-equilibrium forces with strong action and no spinneret and electrohydrodynamics methods to form a power-assisted non-spinning head electromechanical method, which is suitable for use as separation, protection, antibacterial, Ultra-fine material for one or more than one of deodorant, catalytic, sensing, decorative, structural support, biocompatible, storage, controlled release, conductive, repair, medical, healthcare, smart response, aroma, adhesive function The preparation method or the coating method as a material.

For processed materials that cannot be fluidized by dissolution, melting, evaporation, sublimation, plasma, and pulverization, they can be fluidized and can be treated by an interface-assisted non-spinning head electromechanical method by chemical reaction or physical effect. The material to be processed or the reaction intermediate is formed before or during or after the process to fluidize the material to be processed.

B. generating an assist force at an initial electric jet interface of the material to be processed by an external force;

C At the same time, the internal and external forces of the fluid state material generate an assist at the interface of the starting material of the material to be processed.

The effect of the vertical magnetic field on the free surface disturbance effect of the magnetic fluid on the sharp acicular protrusion perpendicular to the surface layer can be combined with other assisting forces to form a boost.

An interface-assisted non-spinning head current body mechanics method characterized by centrifugal force as a boost At this time, the material to be processed is treated by centrifugal force and electrostatic force by attaching the material to be processed to a device capable of generating centrifugal force and capable of applying a high-voltage electric field. The device capable of generating centrifugal force and applying a high-voltage electric field may be a roller, or the material to be processed is located in the container under the roller and the workpiece is attached to the roller when the roller rotates or the processed material is sprayed on the roller from above the roller, and then The roller rotates at a certain speed under the condition of charging, so that the material to be processed is processed under the combined action of centrifugal force and electrostatic force, and the rotation speed is preferably ensured that the centrifugal force does not throw out the material to be processed, but when there is an appropriate electric field effect The force forms a jet to process the material to be processed; the device capable of generating centrifugal force and applying a high-voltage electric field may also be a flat turntable, or the processed material is sprayed on the turntable or the processed material is conveyed to the turntable through the conduit to When the turntable rotates, centrifugal force is formed on the material to be processed, and then an electric field is applied to obtain a centrifugal force and an electrostatic force to obtain a jet and process the material to be processed. In order to ensure a smooth dispersion of the material to be processed on the turntable, it is preferable to embed or engrave a guide strip or a guide groove on the turntable. When centrifugal force is used as the unbalanced force, in order to improve the current body jet effect, it is preferable to have sharp micro needle-like protrusions on the surface of the roller or the edge of the turntable to ensure the tip effect when electrostatically acting.

An interface-assisted non-spinning head current body mechanics method is characterized in that when gravity acts as a boosting force, the fluid state is moved by gravity to the vicinity of the electrode without the spinneret and connected to the power source while being subjected to electric field action and gravity Act to form an electric jet and process the material being processed. In order to enhance the current body jet effect, it is preferable to flow the fluidized material to the electrode of the sharp micro needle-like protrusion at the tip end to ensure the tip effect when electrostatically acting.

An interface-assisted non-spinning head current body mechanics method is characterized in that when the vibration force is used as a boosting force, the fluid state is guided by a material to a plate that can be connected to the vibration machine and the power source and can accommodate a certain amount of fluidized material to be processed. On the structural device, mechanical vibration then generates a vibration force and the power electrode generates an electric field to cause the fluidized material on the plate-like device to form an electric jet under the action of the vibration force and the electric field force and to perform the electric flow on the material to be processed. deal with. In order to improve the current body jet effect, it is preferred that the surface of the plate-like structural device on which the material to be processed is fluidized is a tip-tip fine needle-like protrusion electrode to ensure a tip effect when electrostatically applied. An interface-assisted non-spinning head electrohydrodynamics method is characterized in that when an oscillating force is used as a boosting force, the unbalanced force can be obtained by mechanical vibration outside the container of the material to be processed, or by the material to be processed. The mechanical means of vibration in the container is obtained, for example, by a group of vibrating spikes fixed on the dispersed basket, and can also be obtained by arranging an oscillation generator capable of generating a specific oscillation wave in the container of the material to be processed. When the oscillating force is obtained by the above method, the material to be processed oscillates, that is, the liquid leaves the liquid plane and appears under the surface tension as a structure which is sharp at the tip end and which is widened at the junction with the liquid plane, which is advantageous for the electrostatic action of the tip. As a result, the combination of the oscillating force and the electrostatic force can effectively treat the material to be processed. An interface-assisted non-spinning head current body mechanics method is characterized in that when a bubble burst force is used as a boost, the bubble can be obtained by introducing a gas into a container of a material to be processed, or by inducing a locally processed material or other The material gasification method is obtained by high-speed rotation of the impeller or infrared radiation, microwave radiation, electric furnace wire heating for local operation, and can also be obtained by pressing the gas into the material to be processed and then decompressing by high pressure, and can also be introduced by Obtained in the form of a material that will be vaporized in the material to be processed. After the bubble is introduced into the material to be processed, the bubble inside the material to be processed floats to the surface of the material to be processed because the specific gravity is smaller than that of the material to be processed. However, due to the gravitational effect, the tip of the bubble floating to the liquid surface becomes the weakest. In the part, under the action of the surface tension, the bubble will burst from the top, and at the moment of the bubble bursting, the unbalanced force is generated on the material to be processed and the material to be processed is moved outward. If the material is processed by high-voltage static electricity, The electrostatically applied force can effectively combine the electrostatic force and the bubble bursting force to process and process the material to be processed.

The high velocity fluid is moved by one or more than one conduit passing through the container of material being processed and passed to its liquid level, or by a conduit through the container of material being processed to the vicinity of the level of the material being processed. When a high-speed fluid moves, its high-speed motion generates a negative pressure around it and generates a gravitational force on the material to be processed, thereby increasing the force of the material to be processed in the direction of its electrostatic action. This force is well combined with the electrostatic force. The material to be processed is processed and processed.
