Problems solved by technology

[0005] For a long time, people have tried to use low-temperature sintering technology to produce ceramic thick-film electric heating devices. However, there are always several problems in the produced ceramic thick-film electric heating devices. One is that the thermal shock resistance is poor. Under normal circumstances, crystal porcelain thick-film electric heating devices are prone to cracks, substrate disconnection or / and electric heating film disconnection, causing problems such as failure of the heating device; second, the insulation strength is not high, and it is easy to cause leakage hidden dangers under hot flashes and high temperatures; in addition , this production process also has problems such as large equipment investment, long production cycle, high energy consumption, high production cost and environmental pollution.

[0055] 1. Preparation of glass-ceramic powder

[0056] (11) Preparation of glass-ceramic raw materials, weighing each component according to the ratio described in 4 or 5;

[0057] (12) Ball mill mixing, use a ball mill to mix the various components evenly;

[0058] (13) High-temperature melting, melting the mixed raw materials at 1500-1700 degrees Celsius;

[0059] (14) Water quenching into granules, putting the melted glass-ceramics into water in a linear shape, so that the glass-ceramic liquid is cooled in water to form glass granules;

[0060] (15) Take out the glass grains, and dry the water on the surface of the glass grains at a temperature of 100-120 degrees Celsius;

[0061] (16) Ball mill into powder, put the dried glass particles into the ball mill, and ball mill to 300-1000 mesh for later use.

Description

technical field [0001] The invention relates to the fields of new electric heating devices, new materials and new technologies, in particular a crystal porcelain thick-film electric heating device and a manufacturing method thereof in compliance with EU ROHS standards. Background technique [0002] Conventional ceramic thick-film electric heating devices generally consist of a substrate and an electric heating film attached to the ceramic substrate. This kind of ceramic thick-film electric heating device is usually formed by screen-printing electronic paste on a ceramic green sheet to form an R-shaped heating thick-film wire. , and then press another green sheet with two openings on the R-type heating thick film line, then slowly heat up and deglue, and then sinter at a high temperature (about 1600-1700 degrees Celsius) in a high-temperature furnace protected by hydrogen to become For semi-finished products, electroless nickel plating is applied to the R-type thick film lead...
