The ceramic disc is mainly made of alumina ceramics by molding and sintering, which has the characteristics of drop resistance, wear resistance, super strength, super hard, high temperature resistance (fire resistance), super corrosion resistance, never rust, oxidation resistance, insulation, and its own lubrication And other excellent performance.
The main features of ceramic discs are easy disassembly, high strength and good sealing performance.
When installing the ceramic disc, it is required that the two discs remain parallel. The sealing surface of the ceramic disc must not be damaged and must be cleaned. Ceramic disc gaskets should be selected according to design regulations.
Advantages of ceramic discs
1. High hardness: ceramic materials have high hardness. For example, the hardness of alumina ceramics is HRC89, and the hardness of silicon nitride ceramics is HRC92. It can be used as cutting tools, ceramic discs and other ceramic parts, so the hardness of ceramic discs is very high;
2. Wear resistance: ceramic materials are wear resistant, such as zirconia ceramics and silicon nitride ceramics;
3. High temperature resistance: ceramic materials are resistant to high temperature, such as alumina ceramics and silicon nitride ceramic parts can be used for a long time at a high temperature of 1200-1600 degrees;
4. Corrosion resistance: ceramic discs are generally not rusty, not afraid of oxidation, not afraid of acid and alkali;
5. Good insulation: ceramic materials have good insulation, such as the breakdown voltage of alumina ceramics: 1 mm 15KV (kV);
6. Non-magnetic;
7. Small specific gravity: The density of many ceramic discs is between 1/2 and 1/3 of steel.
Application of ceramic discs
Ceramic discs are mainly used for the connection of cast iron pipes, rubber-lined pipes, non-ferrous metal pipes and flange valves. The connection of process equipment and flanges is also connected by ceramic discs.
