Problems solved by technology

Due to the magnetic field coupling between the medium filaments inside the magnetic medium, the magnetic field distribution is complicated, and there is currently no technical method to effectively analyze or measure the magnetic particle capture behavior and law inside the magnetic medium; thus, when people design the magnetic medium, they mainly Borrowing the theory of "single-filament magnetic capture" (that is, the theory of magnetic capture of magnetic particles by medium single-filament), combined with practical experience, as far as possible in the magnetic medium box without causing blockage of the magnetic medium and under the conditions of the existing processing technology. Fill the media filaments in many places to ensure that they have a large enough adsorption surface area; there is no reliable theoretical basis for the determination of the media filament materials, size, shape, arrangement and combination, and the thickness of the magnetic medium, which cannot ensure the high-gradient magnetic separation process.
