A kind of preparation method of microporous ceramic and microporous ceramic heating rod

Abstract

The invention provides methods for preparing microporous ceramic and a microporous ceramic heating bar. The method for preparing microporous ceramic comprises the steps of preparing materials, grinding, screening, mixing, grouting molding, de-waxing and sintering. In the method for preparing the microporous ceramic, in the step of grouting molding, an electric heating wire of a hollow coil is arranged in a specific mold for molding to form a microporous ceramic heating bar. According to the microporous ceramic heating body, the heating wire and the microporous ceramic are sintered into a whole by adopting grouting molding, so that the heating wire is embedded into the microporous ceramic, the contact area with tobacco tar is increased, the possibility of local dry-burning can be avoided, and the reduction degree and taste of tobacco tar can be improved. The heating wire and the microporous ceramic are sintered into a whole to improve the uniformity of products, and it is convenient to operate. The stability during electric heating works can be effectively ensured, and local dry-burning can be avoided. The heating efficiency of the electric heating wire is improved, and the smoke generation time is shortened.

Description

technical field [0001] The invention relates to the field of microporous ceramics, in particular to a method for preparing a microporous ceramic heating rod used as a heater for heating and atomizing in an electronic cigarette vaporizer. Background technique [0002] At present, there are three main ways for traditional electronic atomizers to heat and atomize. One is to use heating wire to wind glass fiber rope for heating and atomization; the other is to manually wind the heating wire to the surface of the microporous ceramic rod; The wire is embedded in the inner hole of the microporous ceramic rod, the inner hole is roughly 2-5mm, and the outer diameter is 4-8mm. Glass fiber rope, organic cotton, and microporous ceramic rods are all oil-conducting bodies, which are heated by heating wires to atomize e-liquid. In the first two methods, since the heating wires are wound up later, the contact area between the heating wire and the oil-conducting body is small. , it is easy ...

Problems solved by technology

Glass fiber rope, organic cotton, and microporous ceramic rods are all oil-conducting bodies, which are heated by heating wires to atomize e-liquid. In the first two methods, since the heating wires are wound up later, the contact area between the heating wire and the oil-conducting body is small. , it is easy to have insufficient contact, forming a local dry burning situation, which seriously affects the taste of the smoke oil atomization, and the third method, because the microporous ceramic itself is a heat absorber, during the heating process of the heating wire, part of the heat is used for Heating the ceramic body causes the temperature rise of the entire heating wire to be 1-2S slower than the previous two methods, and the time to consume a cigarette is about 2-3S, so it seriously affects the amount of smoke per puff and cannot provide consumers with a good experience.
