The manufacturing method of the embedded far-infrared ceramic heater described by the ceramic heater manufacturer includes the following steps:
Ming aluminum, synthetic mullite, zirconite, sodium feldspar, Suzhou soil, andalusite and alumina super powder were prepared by formula;
After mixing the wet ball mill powder of the mixture, it is made into a slurry, which is grouted. At the same time, the heating wire is embedded in the blank, demolded, and sintered at a temperature of 1050°1100°C, and then the glaze is applied to it. Get the finished product.
Far infrared ceramic heater
In the embedded far-infrared ceramic heater and its preparation method provided by the present invention, the formula of the electrothermal ceramic is expressed by weight percentage, including: bauxite 4-16%, synthetic mullite 5-18%, zircon 18-45% , Albite 2~12%, Suzhou soil 20~40%, Andalusite 3~15%, Alumina ultrafine powder 4~10%, when preparing electric ceramics, firstly bauxite, synthetic mullite, zirconium Alumina ultrafine powder is prepared according to the formula of stone, albite, Suzhou soil and andalusite, and then the batch of wet ball milling powder is mixed to form a slurry to form a slurry, and the heating wire is buried in the blank. Demoulding, and finally sintering at a temperature of 1050_1100℃, and then glazing and firing the glaze to obtain the finished product. The electric ceramic has high thermal shock resistance and strength, long service life, large infrared radiation, good energy saving effect, and strong enhancement. Value.
In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
