New Parts for High Temperature Resistant Insulating Ceramic Pipe in Industry

In the industrial industry, ceramic parts are constantly developing. Today, Kezhong Ceramic Factory will introduce the advantages of ceramic parts, which are commonly used in industrial equipment parts.

Ceramic pipe is a chemical with strong covalent bond, and its Si-C bond inorganic compound is only about 12%. Therefore, it also has physical properties, oxidation resistance, high wear resistance and low friction resistance.

The key application of industrial ceramic tubes is in the production and manufacturing of power electronics technology industry, such as as the casing of high-frequency and high-power rectifier tubes, vacuum tube power switches, etc. Laminated glass was originally used as the raw material of rectifier tube array, but suffered from the problems of high dielectric loss of the raw material itself and rapid heating, which is very easy to lead to tube collapse and other problems. At present, the tubes used in high-power electronic devices are all aluminum oxide (Al203) porcelain. Aluminum oxide ceramics have advantages such as high impact toughness, good dielectric strength, low high-frequency loss, high electrical and compressive strength, heat resistance, and shock resistance. They have unparalleled advantages over glass and are suitable for high-power electronic tubes on the market.

For ceramic products, the first thing everyone needs to do is to break the pipe. It is necessary to first disconnect the pipe fittings according to the required length. Then, when breaking the pipe, we should pay attention not to use too much force, otherwise it may cause the porcelain liquid pipe to become out of round; The next step is to remove the burrs. After the pipe fittings are disconnected, the burrs must be removed thoroughly, otherwise the sealing ring will be cut.

Ceramic pipes have excellent wear resistance and long service life. Smooth surface with low friction coefficient. Low bulk density and light weight; It can resist the corrosion of various acids, alkalis, and salts, with a hardness second only to diamonds. The coefficient of thermal expansion and thermal conductivity are low, and the operating temperature can reach 1000 ℃.

ZTA ceramic tube is a solid electrolyte with porous platinum (Pt) electrodes calcined on both sides. At a certain temperature, due to the different oxygen absorption concentrations on both sides, the oxygen atoms on the higher concentration side (inner side 4 of the ceramic tube) are adsorbed on the platinum level and fused with the electronic device (4e) to produce the oxygen ion O2-. The charge is positive, and the O2- ion migrates to the low oxygen concentration side (exhaust gas side) through the oxygen ion vacancies in the electrolyte, resulting in a negative charge, resulting in a potential difference.
