摘要:
The invention relates to a nanoparticulate preparation which comprises a coherent phase and, disperse therein, at least one particulate phase of superparamagnetic, nanoscale particles having a volume-averaged diameter in the range from 2 to 100 nm, the particles exhibiting a field shift effect, and to a method of heating a nanoparticulate preparation of this kind, it being possible to set different temperatures via variation in the strength of the applied magnetic DC field.

The invention relates to a method and a device for connecting moulded parts, one of said moulded parts consisting of a non-metallic material, by means of at least one adhesive seam consisting of an adhesive which can be hardened by heat. Said moulded parts are respectively inserted, at least in regions, into metallic moulds, at least one of said moulds being provided with a groove along the region of the adhesive seam. The adhesive seam is applied, the metallic moulds and the moulded parts are compressed, and the adhesive seam is heated. The inventive method enables a solution to be created, by which means the necessary heating of the adhesive seam can be carried out between two moulded parts arranged between two metallic moulds in the shortest amount of time possible, in order to accelerate the course of the method. In order to achieve this, a microwave line is inserted into the groove of one of the metallic moulds, and once the metallic moulds and the moulded parts have been compressed, microwaves are introduced into the groove by means of the microwave line in order to heat the adhesive seam absorbing the microwaves.
摘要:
Disclosed is a method for producing a component comprising two adjacent individual parts or molded parts that are to be joined using a thermally hardening adhesive which is placed between the parts and to which a magnetic filler is added. According to the inventive method, at least one portion of the component, especially the adhesive seam located between the two parts, is exposed to polarized electromagnetic radiation, particularly in the wavelength range of microwaves, in order to impinge the adhesive with heat, said radiation being circularly polarized.
