Newly used parts of high temperature resistant insulating ceramic tube in industry

In the industrial industry, ceramic parts are constantly developing. Today, Pintejin Ceramics Factory will introduce the advantages of ceramic parts. This kind of ceramic parts is often used in industrial equipment parts. Ceramic tube is a chemical substance 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. Industrial ceramic tubes are mainly used in the production and manufacture of power electronic technology industrial production, such as the casing of high-frequency power rectifier tubes, electric vacuum tube power switches, etc. Laminated glass is the raw material of the rectifier tube tube type, but suffers from the large dielectric loss of the raw material itself and the rapid heating, which is very easy to cause problems such as tube type cracking. At this stage, the tube type used in high-power electronic devices is all three Alumina (Al203) porcelain. Alumina ceramics have the advantages of high impact toughness, good dielectric strength, low high frequency loss, high electrical and compressive strength, heat resistance, thermal shock and other advantages.

For ceramic products, the first thing you need to do is to break the pipe. Be sure to disconnect the pipe according to the required length. Then we must pay attention when the pipe is broken. Do not use too much force, otherwise it may cause the porcelain riser pipe. The out-of-roundness occurs; the next step is to remove the burrs. When the pipe fittings are broken, the burrs must be removed, otherwise the sealing ring will be cut.

Ceramic tubes have excellent wear resistance and long service life. Smooth surface and low coefficient of friction. It has low bulk density and light weight; it is resistant to corrosion by various acids, alkalis and salts, and its hardness is second only to diamond. The coefficient of thermal expansion and thermal conductivity is low, and the working temperature can reach 1000 ℃. ZTA ceramic tube, which is a solid electrolyte, has a porous structure platinum (Pt) electrode calcined on both sides. At a certain temperature, because the oxygen absorption concentration on both sides is different, the oxygen atoms on the side with higher concentration (the inner side 4 of the ceramic tube) are absorbed on the platinum electrode level and fused with the electronic device (4e) to generate oxygen ions O2-. Positively charged, O2- ions migrate to the low oxygen concentration side (exhaust gas side) through the oxygen ion vacancies in the electrolyte, and negatively charged, that is, a potential difference is generated.
