Embodiment Construction

[0018] The method comprises the following steps: first, adding clean and pollution-free non-metallic materials into the heating chamber 6, and heating under vacuum or protective atmosphere, the lower limit of the heating temperature should be higher than the boiling point of the metal carbonyl complex used for plating, the temperature The upper limit is set according to the temperature tolerance of the material to be plated, the application characteristics of the composite electromagnetic material, and the required thickness of the plated metal. thin, the temperature setting is low; specifically, according to the calculated heat required by the decomposed unit molar volume of the metal carbonyl complex; In the coating chamber 7, if the object to be plated is a particle, the vibration or agitator 11 needs to be turned on, the metal carbonyl complex steam inlet switch 4 is opened, and the metal carbonyl complex steam is input for plating; finally, the plated The completed compos...

Abstract

The invention discloses a method of non-metallic material coating iron magnetic properties and magnetic metal coating and device, which comprises the following steps: pre-heating the non-metallic material in heating chamber (6); making the greatest lower limit of heated temperature higher than the boiling point of coating earbonyl metal complex compound; setting high limit of heated temperature according to the needed coating metal thickness of temperature bearability of the coating material and applicability of composite electromechanical material; transferring to coating chamber (7) with vibration and stirrer (11); feeding in earbonyl metal complex compound steam; coating; transferring to cooling inactive chamber (8); inactivating; cooling; discharging; or getting into the next round heated coating recirculation. This method overcomes the shortcoming of elemental metallic material and meets the need of appliance.

Description

technical field [0001] The invention relates to a method and equipment for coating ferromagnetic and magnetic metal coatings on non-metallic materials, in particular to a preparation method for producing composite electromagnetic materials by using carbonyl metal complexes of ferromagnetic and magnetic metals to coat non-metallic materials and The equipment, in particular, relates to a coating method and equipment for forming ferromagnetic and magnetic material coatings by using carbonyl metal complexes of ferromagnetic and magnetic metals to absorb heat and decompose on heated non-metallic materials. Background technique [0002] Ferromagnetic (iron, cobalt, nickel) and magnetic metal (vanadium, chromium, manganese, molybdenum, technetium, ruthenium, rhodium, tungsten, rhenium, osmium, iridium) materials have a wide range of applications in microwave absorption, conductive fillers for electronic components, and electromagnetic shielding. application, but are unsatisfactory ...
