METHOD FOR PROVIDING A ISOLATION COATING AND ASSEMBLY THEREBY

摘要

PURPOSE: A method for insulation coating and a soft magnetic assembly thereby are provided to minimize the inflow of oxygen through a nitrogen molecule by coating and storing a coating solution including an insulating material in a nitrogen atmosphere. CONSTITUTION: A raw material rolled in a coil type is mounted on an uncoiler(10). The raw material is transferred to a coating solution coating device(30) including a coating solution passing through a correcting device(20). The coating solution comprises a mixing colloid solution of a magnesium methoxide and a magnesium ethoxide. A coating insulating layer is formed by supplying nitrogen gas to the inside of the coating solution coating device. A nitrogen gas storing container(31) is combined with the inside of the coating solution coating device. The nitrogen gas storing container supplies the nitrogen gas to a coating solution storing container(32). [Reference numerals] (AA) Coating solution
