Additional diagram is below coordinated to be illustrated melting electrostatic spinning
In Fig. 3,8 is the high molecular melting mechanisms of thermoplasticity, and 5 is the high molecular polymer shower nozzles shooing out high molecular polymer after fusing, and 6 is the High Temperature High Pressure air nozzles out extended from high molecular polymer shower nozzle spray 5 by the thermoplasticity macromolecule of fusing; 7 be located at ejection melt after high molecular polymer shower nozzle 5 allow above the electrode (also i.e. electrostatic generator) of electrostatic on polymer strip, 9 is interdict for inducing the dry blocking insulation board of scratching of the electrostatic field of electrostatic nanofiber.
The generative process of nanofiber: thermoplasticity high molecular polymer 1 is heat fused on melting mechanism 8, macromolecule after fusing spues from high molecular polymer shower nozzle 5, and gases at high pressure 2 spray the macromolecule extension elongation of fusing from High Temperature High Pressure air nozzle 6 simultaneously.Add between electrostatic generator 7 and high molecular polymer shower nozzle 5 that high tension voltage produces electrostatic, makes homopolarity electrostatic on polymer strip, produces repulsive interaction and macromolecule more can be extended before solidifying, produce nanofiber between same electric charge simultaneously.
High molecular tensile force is by the domination of high-speed and high-temperature air, and the air-flow of high-speed and high-temperature causes the draught head air-flow driving the slow air-flow of surrounding air to be formed centered by high-temperature high-speed airflow.Fusing macromolecule slug flow of postponing enters high-speed central and to be stretched shaping.Need the layer that flows slowly, be just unlikely to macromolecule and be pulled off before uncured.
The speed of high velocity air is too high, does not slowly improve the unhurried current layer of flow velocity, and draught head is large, and macromolecule is broken before curing, does not become long fiber.As shown in Figure 4.Unhurried current layer can be formed within the scope of pressure and temperature of the present utility model
High molecular discharge opening 5 is adjustable with the spacing of high speed and high pressure ejiction opening 6.Distance is too near, and draught head is too large, and macromolecule can not get extending, and easily becomes particle.Within the scope of pressure and temperature of the present utility model, can suitably regulate.
Here, high-speed and high-temperature air nozzle 6 is adjustable with the position relationship of macromolecule discharge opening.Apart from too far away, first can not be involved in by high velocity air, and the second high molecular temperature decline viscosity improves.Within the scope of pressure and temperature of the present utility model, can suitably regulate.
The macromolecule simultaneously melted contacts with air and also can cool rapidly, and viscosity improves.
Here as shown in Figure 5, high temperature and high speed air nozzle 6 front portion is provided with a heater.Rapid expansion after compressed air heating, high-speed gas obtains accelerating sooner.More than air heat to the macromolecule temperature of fusing delay the cooling velocity of liquid macroimolecule simultaneously.
As shown in Figure 3, thermoplasticity macromolecule fusing pusher spues by heat fusing mechanism 8 after the shower nozzle 5 being attached with high-pressure electrostatic.Electric charge on the polymer strip of fusing, due under the mutual repulsion (Coulomb force effect) of same sex electric charge and the effect of high-speed and high-temperature wind-force between fusing macromolecule, fiber is more tiny.Different electrodes electrostatic brought by collector 10, attracts to collect to form nano fibrous membrane by bringing the nanofiber of electric charge.The nano fibrous membrane of such collection can utilize as dress materials, heat-barrier material, sound-absorbing material, oil absorption material etc.
The nanofiber that the utility model obtains is long fiber, easy-to-use.
The utility model is incessantly described above utilizes scope, along with the development of technology from now on, the specific area characteristic (many reactions can only produce at material surface) of its super large can be utilized, the nanofiber institute characteristic properties such as the intermolecular active force of nanofiber, wait in expectation in deeper medical technology, domestic life, the exploitation in Space Science and Technology field.The technology of a large amount of generation nanofiber has high utility model and is worth.
The foregoing is only preferred embodiment of the present utility model, and be not used to limit substantial technological context of the present utility model, substantial technological content of the present utility model is broadly defined in the right of application, any technology entities that other people complete or method, if with application right define identical, also or a kind of change of equivalence, be all covered by being regarded as among this right.
The all documents mentioned at the utility model are quoted as a reference all in this application, are just quoted separately as a reference as each section of document.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read foregoing of the present utility model, these equivalent form of values fall within the application's appended claims limited range equally.
