Problems solved by technology

[0002] At present, there are many kinds of heating elements used in the market, among which the more representative ones are metal nickel-chromium wire heating elements, silicon carbide heating elements, and PTC heating elements, and some use electrothermal film to generate far-infrared radiation. They are suitable for low temperature, The temperature rise is relatively slow, and generally additional insulation is required to achieve the purpose of safe use

Embodiment Construction

[0006] The following materials are selected: metal, ceramic plate, ceramic sintering aid, nickel electrode, silver brazing, nickel alloy wire and temperature controller.

[0007] Adjust the metal into a metal paste, print it on the surface of the ceramic substrate with a screen, let it dry naturally, and then put it in a hydrogen furnace at 1300-1600°C for ceramic metallization, so that the surface of the ceramic is formed The metal heating element with metallic luster, in order to prevent the metal from oxidizing during the working process, another ceramic plate with a gap is covered on this side. The gap mainly exposes the metal for external connection of wires. In the two ceramic plates Apply some ceramic sintering aids, sinter them together under the condition of 600-1600°C, plate the exposed metal on the bonded ceramic plate with nickel, and weld nickel-gold wires here with silver solder by generalists. Fusion welding is performed in a hydrogen furnace. Due to the wide r...

Abstract

The molten metals is printed on the surface of ceramic, which is then carried out ceramic metallization in hydrogen combustion furnace by using wet hydrogen. Then, one layer of ceramics sintering auxiliary agent is coated on the metal ceramic plates sintered. Another ceramic plate with notch is covered on the said ceramic plate and agglutinated each other. Then, the sintering procedure is processed for agglutinated two ceramic plates in furnaces again. Nickel is plated on the electrode on the said notch of the ceramic plate. Fusion welding is carried out in the place, where nickel is plated, for leading out the wire for use in high temperature by using silver solder. Finally, the thermostat is connected to the wire for temperature control.
