Ceramic liquid guide substrate, atomizing core and preparation method of ceramic liquid guide substrate and atomizing core

Abstract

The invention discloses a preparation method of a ceramic liquid guide matrix and an atomizing core. The preparation method comprises the following steps: 1, uniformly mixing resin, ceramic powder, a sintering aid and a pore forming agent to prepare stable and uniform ceramic slurry; 2, laminating and laying a plurality of layers of fiber nets on a flat plate mold; 3, the ceramic slurry is poured into the multiple layers of fiber nets in a vacuum infusion mode, and a ceramic green body is obtained after curing; 4, performing high-temperature sintering on the ceramic green body, and removing resin, fibers and a pore-forming agent in the ceramic green body to obtain a ceramic plate simultaneously provided with an orthogonal hole liquid guide runner and a random hole liquid guide runner; 5, cutting the ceramic plate to a proper size, and polishing to obtain a required orthogonal hole ceramic liquid guide matrix; and 6, a heating film is manufactured on the atomization face of the orthogonal hole ceramic liquid guide base body, and the ceramic atomization core with the orthogonal hole flow channel is obtained. According to the preparation method of the ceramic liquid guide base body and the atomization core, the problems that an existing straight-through hole atomization core is insufficient in liquid storage amount, and the gas return phenomenon is prone to occurring are solved.
