Abstract

The present invention provides a method for preventing the adhesion of deposits, which is a fluid treatment method, a thin film produced between at least two processing surfaces that are arranged opposite, can be approached and separated, and at least one of them rotates relative to the other. The fluid to be treated is mixed with the fluid to obtain a treated material, and the treated material is prevented from adhering to the above-mentioned processing surface constituting the flow path of the treated fluid. Using at least two types of fluids to be treated, including a raw material fluid containing at least one raw material and a fluid used to process the above-mentioned raw material, are arranged in opposite directions, can be approached and separated, and at least one of them is relatively opposite to the other. The fluid to be treated is mixed with the thin film fluid generated between the rotating at least two processing surfaces (1, 2) to obtain a processed raw material. At this time, by introducing the raw material fluid from the center of the processing surfaces (1, 2), the raw materials processed between the processing surfaces (1, 2) are prevented from adhering to the processing surfaces (1, 2).

Description

technical field [0001] The present invention relates to a method for preventing attachment of deposits. Background technique [0002] Microparticles are required in the entire industrial field, ranging from micron-sized particles to nano-sized particles, and it is necessary to manufacture particles separately according to the intended use. In particular, nanoparticles (nano-sized particles), which are particles with a particle diameter of less than 1 μm, exhibit new characteristics different from particles, and therefore it is necessary to develop a new production method for industrially producing nanoparticles. Conventional production methods for micron-sized microparticles have problems of reproducibility and energy consumption. Therefore, a production method for microparticles that can easily control the particle size from micron to nanometer is desired. [0003] In order to solve the technical problems and problems of the conventional "microchemical processing technolog...
