    Abstract: The invention relates to a method for producing multi-layered lignocellulose materials having a core and an upper and a lower cover layer, said method comprising the following steps a) mixing the components, b) spreading the mixtures in layers, c) pre-compressing, d) applying a high-frequency electric field e) hot pressing. According to the invention, a mixture of C) 1-15 wt.-% of a binding agent selected from the group consisting of aminoplastic resin and organic isocyanate having at least two isocyanate groups [components C)], F) 0.1-3 % alkali-/akaline earth salts, for the cover layers of the lignocellulose particles G) with H) 1 - 15 % of a binding agent selected from the group consisting of aminoplastic resin and an organic isocyanate is mixed. After step a) the mixture for the core contains, with respect to the total dry weight of the mixture of the components A) - F) 3-15 % water, the mixture for the cover layers of the components G) - K) contains 5 - 20 % water, and the following conditions are met: F) ≥ 1,1 ● components K) and [components F) + components D)] ≥1,1 ● [components K) + components I)].

    Abstract: The invention relates to a method for measuring deposits in the interior (12) of an apparatus (10) by using microwave radiation, comprising the following steps: a) arranging at least one microwave resonator (20) in the interior (12) of the apparatus (10), wherein the interior (36) of the microwave resonator (20) is connected to the interior (12) of the apparatus (10) in such a way that mass transfer can occur, or designing the interior of the apparatus (10) as at least one microwave resonator (20), b) introducing microwave radiation into the at least one microwave resonator (20), and c) determining a resonance frequency and/or a quality of a resonance of the at least one microwave resonator (20), wherein steps b) and c) are repeated and the amount and/or the type of the deposits in the interior (12) of the apparatus (10) is inferred from a change in the resonance frequency and/or the quality of a resonance of the at least one microwave resonator (20). The invention further relates to a device for performing the method.
