The invention provides a method 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 bar prepared by a novel manufacture process, the
electric heating wire and the microporous ceramic are sintered into a whole by adopting grouting molding, so that the
electric 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 electric heating wire and the microporous ceramic are sintered into a whole to improve the uniformity of products, and is convenient to operate; the stability during thermal heating work can be effectively ensured, local dry-burning can be avoided; and the
heating efficiency of the electric heat wire is improved, the
smoke generation time is shortened, and the smoking experience of users is promoted.
