HYDROSOL PREPARATION METHOD Russian patent published in 2022 - IPC B01J13/02 

FIELD: colloid chemistry.

SUBSTANCE: invention relates to colloid chemistry, more specifically to electro-erosion treatment of liquid with a series of fast-flowing electrical discharges between electrodes with the formation of a suspension of nanoparticles of their materials, characterized by biocide properties. When preparing hydrosol, electrical voltage is supplied to coaxial electrodes placed in dielectric liquid. Voltage is supplied in the form of high-frequency pulses with sharp front and rear fronts, each of which provides flowing the process with exacerbation. In an automatically regulated inter-electrode gap, a steam bubble is formed, where, then, the pulse electrical discharge is ignited, accompanied by electrode erosion with the formation of nanoparticles and ions. Electrical voltage of 4-10 kV is supplied, by means of a discharge capacitor, to electrodes, the inter-electrode gap of which is kept in a range of 20-100 mcm, for structuring the pulse electrical discharge by an arc of pulses in a number of three with duration of 1 ns-1 mcs. Plasma is formed in the steam bubble, localizing a temperature of 10⁶-10⁸ K for a time of discharge.

EFFECT: safe conduction of high-temperature processes is provided.
