POROUS SPRAYING CORE CONFIGURED TO RELEASE NEGATIVE IONS, AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2024 - IPC A24F40/70 C04B38/06 A24F40/44 

FIELD: liquid atomisation or spraying devices.

SUBSTANCE: group of inventions relates to a porous spraying core configured to release negative ions and a method for production thereof. Porous spraying core configured to release negative ions includes raw materials, in weight fractions, as follows: 50–90 weight fractions of tourmaline, 0–30 weight fractions of ceramic powder, 10–30 weight fractions of a pore-forming agent, 0–30 weight fractions of a sintering additive, 0–35 weight fractions of paraffin and 0–2 weight fractions of a surfactant. Ceramic powder contains at least one of powder-source of negative ions, powder-source of far infrared radiation, attapulgite clay, feldspar and zeolite. Tourmaline is a primarily modified tourmaline, wherein the primary modified tourmaline is obtained by the following modification method: adding 100 weight fractions of tourmaline to a hydrated solution of cerium nitrate with a weight fraction of 1–10%, placing it in a chromatographic column for cyclic overload for 2–5 hours, and then magnetically stirring the overloaded suspension, slowly dropping aqueous ammonia with a weight fraction of 5–10% and stopping the dripping when the pH value is 10, then adding pure water and stirring, washing several times, the transparent liquid is filtered, dried in an oven at temperature of 70–90 °C, and then placed into a sintering furnace and calcined at temperature of 500–600 °C for 4–6 hours. Providing reduction of probability of electron-hole recombination, causing surface of composite material tourmaline/Ce to accumulate a large amount of energy, which leads to increased release of negative oxygen ions.

EFFECT: porous spraying core is environmentally friendly and has good spraying effect, which satisfies the desire of people to healthy products and simultaneously increases service life of the spraying core.
