Problems solved by technology

[0008] However, the MCH co-fired ceramic heating substrate disclosed above and its preparation method need to be sintered under the protection of a hydrogen atmosphere at 1600°C, which not only has high production costs, but also has a high risk factor and is prone to explosion, which is not conducive to widespread promotion.

Abstract

The invention discloses a method for preparing a heating non-burning smoking set ceramic substrate rare earth thick film heating sheet. The method comprises steps that S1, two through holes are arranged in a ceramic substrate; S2, the through holes are filled with electrode slurry, and connection circuits are printed on front and back sides of the ceramic substrate; S3, rare earth thick film circuits are printed on the front and back sides of the ceramic substrate; and S4, a protective layer is printed. The method is advantaged in that processing steps are simple, operation is simple, in the smoking set technology field, defects of high production cost, high risk factor and easy explosion of traditional MCH ceramic heating bodies are overcome, the rare earth thick film material is appliedto the smoking set field to produce the heating sheet, production cost is greatly reduced, non-easy damage, high safety factor and easy wide promotion are achieved, rare earth thick film electrodes are printed on both sides of the ceramic substrate, resistance of the heating sheet can be reduced, the heat generation rate is improved, and consistency of the heating temperature on the front and backsides of the heating sheet is improved.

Description

technical field [0001] The invention relates to the technical field of smoking utensils, in particular to a method for manufacturing a heating sheet of a ceramic base material of a heat-not-burn smoking utensil. Background technique [0002] Cigarettes are a kind of tobacco products. Many people like to smoke cigarettes to relieve stress and refresh themselves. Regular smoking of cigarettes will lead to addiction. Tobacco will produce tar, nicotine, carbon monoxide, etc. when burned. Harmful, and the harm of second-hand smoke is greater than that of first-hand smoke, so many public places will have smoking ban measures, and when smoking tobacco will produce open flames, which can easily cause fires, so people have created a heat-not-burn smoke, heat-not-burn smoke It can meet the needs of smokers, and can reduce the content of tar and nicotine, so it is sought after by smokers. [0003] However, most of the existing heat-not-burn cigarettes are heated by resistance heating....
