Embodiment 1
[0054] The magnetic field orientation device and method for tape casting of magnetic materials provided by the embodiments of the present invention are used to prepare a magnetic thin film in which magnetic fillers are oriented vertically or along the length direction of the film.
[0055] The magnetic field orientation device for tape casting of magnetic materials provided in this embodiment includes a tape casting machine and its support (not shown in the drawings), and also includes the first limiting pair of rollers 1 and the magnetic field orientation roller sequentially arranged on the support. 3, the second position-limiting pair of rolls 2, and the cast base tape 4 passing through the first position-limiting pair of rolls 1, the magnetic field orientation roll 3, and the second position-limiting pair of rolls 2 in sequence; The slurry is scraped and coated by a scraper, etc.) The cast slurry to be tape-casted, the slurry includes magnetic fillers to be oriented; in this...
Embodiment 2
[0072] The magnetic field orientation device, method and product provided by the embodiment of the present invention are basically the same as the embodiment 1, and it is used to prepare a magnetic thin film in which the orientation of the magnetic filler is perpendicular to the length direction of the film. The difference is that:
[0073] In the magnetic field orientation device for tape casting of magnetic materials provided in this embodiment, the horizontal height of the top arc section where the magnetic field orientation roller 3 is in contact with the casting base tape 4 is higher than the position where the first limiting pair of rollers 1 contacts the casting base tape 4 Horizontal height, at the arc-shaped top position of this section, the casting base belt 4 is lifted upwards, so that the casting base belt 4 forms a slope of 2 to 8° between the first limiting pair of rollers 1 and the top of the magnetic field orientation roller 3 , that is to form an uphill sectio...
Embodiment 3
[0085] The magnetic field orientation device, method and product provided by the embodiments of the present invention are basically the same as those in Embodiments 1 and 2, and are used to obtain a magnetic field in which the orientation of the magnetic filler is aligned along the length direction of the film. film. The difference is that:
[0086] In the magnetic field orientation device tape-casting of the magnetic material, the horizontal height of the top arc section of the magnetic field orientation roller 3 contacting the casting base tape 4 is higher than the horizontal height of the position where the second limiting pair of rollers 2 contacts the casting base tape 4, The casting base tape 4 is lifted up at the position of the top arc section, so that the casting base tape 4 forms a slope of 2 to 8° between the second position-limiting pair of rollers 2 and the top of the magnetic field orientation roller 3, that is, a gradient from the magnetic field is formed. The ...
