Abstract

The invention provides an instant ceramic heating tube comprising a ceramic rod and a resistive film. According to the resistive film, an aluminum oxide green tape serves as a substrate, and a tungsten metal heating circuit film is printed on the substrate. An external electrode is lead out through brazing of the tungsten metal heating circuit film. The aluminum oxide green type wraps the ceramic rod. The aluminum oxide green tape and the ceramic rod are fired together and form a whole. A preparation method of the instant ceramic heating tube comprises the steps that firstly, the ceramic rod and the resistive film are prepared, the ceramic rod is coated with the resistive film, hot-pressing and co-firing are conducted, and the instant ceramic heating tube is formed. The instant ceramic heating tube is simple and compact in structure, high in temperature rising speed, even in heating, resistant to corrosion, environmentally friendly, and capable of saving energy.

Description

technical field [0001] The invention relates to a ceramic heater, in particular to an instant ceramic heating tube and its processing technology. Background technique [0002] At present, the common copper heating pipes, water storage heaters, and gas heaters currently in use have complex structures, large volumes, slow heating speeds, low safety performance, large energy consumption, and poor environmental protection performance. The ceramic heater is a heater with high efficiency and uniform heat distribution, which can ensure uniform temperature on the hot surface, eliminate hot spots and cold spots of the equipment, and has the advantages of long life, good thermal insulation performance, strong mechanical properties, corrosion resistance, and anti-magnetic field. . Therefore, it is necessary to design an instant ceramic heater to heat the water flowing through the ceramic tube and supply it to the heating tube water heater.
