What causes the surface cracking of ceramic saddle ring

Ceramic rectangular saddle ring is a kind of high efficiency filler widely used in chemical industry, environmental protection and other fields, its surface cracking phenomenon is often closely related to many factors. From the point of view of the material itself, the brittleness of ceramic materials is one of its inherent attributes, if the raw material ratio is improper in the production process, the sintering temperature control is not accurate or the cooling speed is too fast, it may lead to the uneven distribution of internal stress, and then in the subsequent use of the process due to changes in the external environment (such as temperature changes, pressure fluctuations) caused by cracking.

Secondly, the use environment is also a factor that cannot be ignored. Under harsh conditions such as strong acid, strong alkali or high temperature and high pressure, the ceramic saddle ring is subjected to chemical corrosion and physical stress for a long time, and the surface structure will gradually become fragile, and cracks may start and expand in these weak points. In addition, fluid erosion is also an important cause of cracking, especially at high flow rates, the impact force of the fluid on the surface of the filler increases, accelerating the wear and cracking process of the material surface.

In addition, improper behavior during installation and operation can also be an incentive. For example, excessive force during installation causes damage to the packing, or abnormal fluctuations in system pressure, temperature and other parameters during operation may adversely affect the ceramic torque saddle ring and cause its surface to crack.

To sum up, the surface cracking of ceramic rectangular saddle ring is a complex multi-factor problem, involving material properties, use environment, installation operation and many other aspects. In order to effectively prevent and control the cracking phenomenon, it is necessary to start from the source, optimize the production process and ensure the quality of materials; At the same time, strengthen equipment maintenance, reasonable control of operating parameters, reduce the negative impact of the external environment on the filler. In addition, regular inspection and replacement of aging and damaged packing is also an important measure to ensure the stable operation of the system.
