How long is the service life of industrial ceramics?

Industrial ceramics are mainly divided into zirconia ceramics and alumina ceramics. Many people don't know very much about zirconia ceramics, zirconia ceramics have many advantages, and now more and more products use zirconia ceramics processing. Such as our water spray spinning machine industry ceramic spray needle, ceramic plunger, scissors sheet and so on. In the actual industrial production, many other enterprises also need to use zirconia ceramics processed parts, compared with other material parts, zirconia ceramic parts are better, so how long is the service life of zirconia ceramics?
Zirconia ceramics can generally be used for a year. The main reason is the death of nitrification bacteria. Although most of their bodies are washed away with the current, some still remain in the ceramic gap, which slowly blocks the gap in the back. The parasitic effect of the ceramic ring will gradually decrease and reach its service life, so it needs to be replaced regularly.
As time goes by, you will find the color of "ceramic", "white", "yellow" and "dark yellow" changes, which is because the impurities in the water have blocked the "ceramic" surface gap, even if the cleaning will not achieve satisfactory effect!
The alumina ceramic system is divided into 99 porcelain, 95 porcelain, 90 porcelain, 85 and other varieties according to the AI203 content, sometimes A1203 content in 80% or 75% is also classified as ordinary alumina ceramic series.99 alumina porcelain material is used for making high temperature storage yard, refractory furnace pipe and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valve pieces, 95 alumina porcelain is mainly used as corrosion resistant, wear-resistant parts; 85 porcelain is often mixed part talc, improve electrical performance and mechanical strength, can be sealed with molybdenum, niobium, tantalum and other metals, some field as electric vacuum device. Compared with zirconia ceramics, alumina ceramics have relatively better performance and longer service life.
Although it is easy to associate ceramic materials to fragility, in fact, they are much superior to traditional ceramics in terms of physical properties due to the special addition of alumina ceramics. Qualified alumina ceramic products hardness level is very high, in the case of extrusion, collision will not occur damage
