Problems solved by technology

[0003] The ceramic coating mixture involved in the Chinese utility model patent with the authorized announcement number CN2741957Y and the Chinese invention patent application with the publication number CN101792128A has good electrical conductivity, but its ozone corrosion resistance is insufficient, while the anti-corrosion in the prior art Most ceramic materials do not have electrical conductivity or have poor electrical conductivity and are generally resistant to ozone corrosion. Studies have found that zirconia is often used in the preparation of ceramic materials because of its high resistivity, high refractive index and oxidation corrosion resistance. Dititanium trioxide has a strong anti-acid and alkali corrosion effect, especially concentrated sulfuric acid corrosion. If the two are combined, it is possible to develop a protection against ozone corrosion, strong acid and alkali ability, high conductivity and in line with the ozone industry. coating

Abstract

The invention relates to a ceramic coating composition and a preparation method and application thereof. The ceramic coating composition comprises dititanium trioxide, zirconium oxide, magnesium oxide, sodium sulfate and zinc oxide. The preparation method includes the steps of weighing all components according to a formula proportion and evenly mixing the components in a stirrer so as to obtain the ceramic coating composition. The ceramic coating composition has the advantages of electricity conductivity, resistance to acid, alkali and ozone corrosion and light specific weight, is capable of preventing the ozone generating tubes from being corroded by ozone effectively and increasing ozone output and is particularly suitable for ozone generating tubes of the ozone industry.

Description

technical field [0001] The invention relates to the field of surface engineering, in particular to a ceramic coating composition and its preparation method and application. Background technique [0002] Ozone generators, especially large-scale ozone generators, are widely used in industry. The mechanism of action of ozone generators is no stranger to the industry. You can also get more detailed information through the Chinese utility model patent with the authorized announcement number CN2741957Y. learn. The ozone generating tube, also known as the metal electrode tube, is the core unit of the ozone generator. Studies have shown that the ozone generating tube is easily corroded by ozone, and the corrosion of the ozone generating tube by ozone will lead to attenuation of ozone production. According to statistics, if the ozone generating tube is used for one year without a protective layer, the ozone production will drop sharply by 30%-50% due to the corrosion of the ozone g...
