Description
Affiliated technical field
The present invention relates to little paper tinsel of a kind of double-colored magnetic and manufacture method thereof and based on the new magnetism display method of the little paper tinsel magnetic force property of this double-colored magnetic.Based on this magnetism display method, utilize magnetic force to write and can make the magnetic display not produce the purpose that realizes writing and wiping literal or graphical information on the basis of dirt bits with erasing apparatus, and magnetic display and magnetic force writes and erasing apparatus is all reusable.
Background technology
At present, knownly utilize magneto motive display packing to be mainly used in picture to write formative education children's stationery such as plate.Basic principle is that magnetic that the white background liquid by many black magnetic particulates and certain density and viscosity mixes shows that liquid is encapsulated in the transparent thin board with latticed space or utilizes microcapsules technology to be made into transparent microcapsules again with its coating and be laminated on the transparent thin board that scribbles bonding agent in advance and make magnetic display (main application at present is that picture is write plate) earlier.The magnetic particulate here normally monochromatic and mainly be to make by the method that the mineral grain that directly will have magnetic grinds.During use, by magnetic display (picture is write plate) just or the reverse side magnetic field that applies certain intensity is attracted black magnetic particulate under magneticaction and attached to the front or the reverse side of magnetic display (picture is write plate).When being adsorbed to the front; black magnetic particulate can be according to the shape of externally-applied magnetic field and movement locus thereof and is arranged in certain figure; the black magnetic particulate that is in the white background liquid outside the magnetic field then is not adsorbed to the front, thus this moment from top view to be exactly the figure of the black under the white background.When needs are wiped the figure of front black, then must apply the magnetic field of certain intensity at the correspondence position of this magnetic display (picture is write plate) reverse side, be adsorbed onto reverse side will be adsorbed to positive black magnetic particulate, under the covering of white background liquid, just can't see the figure of black like this from the front.But, only require the operation that not only write but also wiped in magnetic display one side in many cases, and present magnetism display method obviously can't be accomplished this point effectively, so this has also limited magnetic Display Technique applying in more areas to a certain extent.
Summary of the invention
Can not write deficiency with erase operation in the same one side of magnetic display in order to solve present magnetism display method, the present invention proposes the little paper tinsel of a kind of double-colored magnetic and manufacture method thereof and based on the new magnetism display method of the little paper tinsel of this double-colored magnetic.This new magnetism display method has two kinds of different mode of operations, the operation that the energy assurance writes and wipes both can be carried out at the tow sides of magnetic display, also can carry out, thereby be apply the created condition of magnetic Display Technique in more areas in the same one side of magnetic display.
The technical solution adopted for the present invention to solve the technical problems is: make the little paper tinsel of a kind of double-colored magnetic earlier, the South Pole of the one side exhibit magnetic properties of this little paper tinsel, the arctic of another side exhibit magnetic properties.Make the two sides have different colours, for example: south face is white, and north pole face is black.The method of making the little paper tinsel of this double-colored magnetic can be such: utilize the present magnetic coating technique and the technology that magnetizes to make a kind of have certain density and Surface field intensity earlier, single face polarity one s causes and two sides polarity is opposite and the two poles of the earth, north and south face look different magnetic flakes, and the microsheet that more such magnetic flakes is ground into the certain particle size size is to obtain the little paper tinsel of double-colored magnetic.Thousands of so little paper tinsels of double-colored magnetic are distributed in the background liquid of certain color, density and viscosity equably, and are in suspended state, and such mixing material can be called magnetic and show liquid.Magnetic shows that liquid is the core material that the present invention will use.In concrete the application, can utilize microcapsules technology as the wall material magnetic to be shown that the fluid-tight dress makes many microcapsules with the material of residuite, and can utilize the cylinder coating technique these microcapsules to be applied on the transparent thin board that scribbles the very thin bonding agent of one deck in advance, make a kind of magnetic display as thin as a wafer by lamination again, also can make the magnetic display by magnetic being shown liquid directly is encapsulated in the latticed space between the two-layer transparent thin board.
During practical operation, this magnetic display must cooperate magnetic force to wipe and writing station ability operate as normal.
When in the color of background liquid and all the two poles of the earth, double-colored magnetic little paper tinsel north and south wherein one side had solid colour the time, both can also can be with two-sided erasable pattern work with the erasable pattern work of single face.
When working with the erasable pattern of single face, its operation principle is such: can apply the directional magnetic field of a definite shape and intensity and make its front of skimming over this magnetic display equably (display surface) by the magnetic force erasing apparatus earlier.If by above giving an example, the south face of the little paper tinsel of double-colored magnetic in being distributed to background liquid is white, north pole face is a black, and this moment as the color of background liquid are when also being white, so as long as the externally-applied magnetic field direction is that the arctic is towards magnetic display front (display surface) at this moment, just can make all be in the upset that fixed orientation takes place for the little paper tinsel of double-colored magnetic in the action of a magnetic field zone under magneticaction according to repel each other the principle that there is a natural attraction between the sexes of the magneto motive same sex, its south face is that white face is towards the display front, north pole face is that black side is towards the display back side, simultaneously the little paper tinsel of double-colored magnetic also can be attracted under magneticaction and attached on the top layer transparent thin board or near the microcapsules top in display front, this moment from the top view of display to be the background color background colour of this magnetic display just of white, in the time will demonstrating the figure of definite shape and live width in the front of magnetic display, only need apply the directional magnetic field of certain intensity and shape by the magnetic force writing station in its front, magnetic direction is that the South Pole is towards magnetic display front.Magnetic under this magnetic field institute stop place shows that the upset of the fixed orientation of similar front erase process promptly can take place the little paper tinsel of double-colored magnetic in the liquid under magneticaction like this, making its south face is white face magnetic display front dorsad, and north pole face be black side towards magnetic display front, simultaneously the little paper tinsel of double-colored magnetic also can be attracted on the top layer transparent thin board or near the microcapsules top in magnetic display front.This moment from the top view of magnetic display to be the figure that has occurred black the background colour of white.Because the comprehensive function of the effect of sticking of the little paper tinsel of double-colored magnetic itself and gravity, buoyancy etc., even remove that magnetic force is wiped or the externally-applied magnetic field of writing station after, they also can rest on original position and keep the state of itself, so just shown image are kept.When needs are revised original picture material or write new picture material again, only need adopt foregoing magnetic force to wipe the flip-flop movement of controlling the double-colored magnetic little paper tinsel of a certain regional magnetic in showing in the liquid with the magnetic field of the fixed-direction of writing station by applying certain intensity and shape and can realize wiping the operation of rewriting and rewriteeing.
When working with two-sided erasable pattern, its operation principle is such: apply the magnetic field of a definite shape and intensity and make it skim over the reverse side of the display surface of this magnetic display equably by the magnetic force erasing apparatus, at this moment, the little paper tinsel of double-colored magnetic is attracted under magneticaction and attached on the bottom transparent thin board or near the microcapsules of magnetic display reverse side bottom, because the color of the little paper tinsel of double-colored magnetic this moment is covered by the color of background liquid, therefore from the top view of magnetic display to be the i.e. background colour of this magnetic display of color of background liquid, in the time will demonstrating the figure of definite shape and live width in the front of magnetic display, only need apply the directional magnetic field of certain intensity and shape by the magnetic force writing station in its front, magnetic direction is that the South Pole is towards magnetic display front, originally like this be attracted on the bottom transparent thin board or show that near the microcapsules bottom magnetic of magnetic display reverse side the upset that orientation will take place for the little paper tinsel of double-colored magnetic in the liquid is adsorbed on the top layer transparent thin board or the microcapsules top in close display front simultaneously under magneticaction, and to make its south face be white face magnetic display front dorsad, and north pole face be black side towards magnetic display front, this moment from the top view of magnetic display to be the figure that has occurred black the background colour of white.When needs are revised original picture material or write new picture material again, only need adopt foregoing magnetic force to wipe the flip-flop movement of controlling the double-colored magnetic little paper tinsel of a certain regional magnetic in showing in the liquid with the magnetic field of the fixed-direction of writing station by applying certain intensity and shape and can realize wiping the operation of rewriting and rewriteeing.
When the color on the color of background liquid and the little paper tinsel south poles of double-colored magnetic two sides is all inconsistent, its action need that writes and wipe carries out on the two sides of magnetic display respectively, promptly can only be with two-sided erasable pattern work, but can realize double-colored demonstration this moment by the magnetic field that applies different directions when the write operation.This be owing to: when with the action of a magnetic field of different directions when the display surface of magnetic display carries out write operation, though magnetic shows that the little paper tinsel of double-colored magnetic in the liquid all can be attracted and attached to will being different polarity on the top layer transparent thin board or near its side towards display surface of microcapsules top in magnetic display front.For example when the magnetic force writing station applies a South Pole towards the directional magnetic field of magnetic display display surface, the little paper tinsel of double-colored magnetic will be its north pole face towards magnetic display display surface, and this moment, the top view from the magnetic display was the color of the little paper tinsel north pole face of double-colored magnetic to graphic color; Otherwise, then be the color of its south face.
In magnetism display method proposed by the invention, the magnetic of being made up of little paper tinsel of double-colored magnetic and background liquid in the magnetic display shows that liquid is separated into the range of movement of several zonules with the little paper tinsel of restriction magnetic, area size is determining display precision, that is: each zone constitutes a pixel; The shape in the magnetic field of the size of pixel and the display surface that acts on has determined the live width of shown image.
The invention has the beneficial effects as follows: thisly can guarantee that based on the made magnetic display of the magnetism display method of the little paper tinsel of double-colored magnetic the operation that writes and wipe both can carry out in the opposite sides of magnetic display, also can carry out in the same one side of magnetic display, when the color on the color of background liquid wherein and the little paper tinsel south poles of double-colored magnetic two sides is all inequality, can also realize double-colored demonstration, and magnetic display and magnetic force write and erasing apparatus is all reusable, and this just is apply the created condition of magnetic Display Technique in more areas.
