Ceramic Ring Sheet
Product Description
White Ceramic Ring is miniature transmission or positioning components designed for high precision, long life, and special environments. Through the superior comprehensive properties of ceramic materials, they overcome the bottlenecks of traditional metal parts in terms of wear resistance, lubrication, contamination, corrosion resistance, and lightweighting, becoming a core component for achieving reliable motion functions in precision instruments, high-end equipment, and miniaturized products.
Product Advantage
| Feature Category | Intrinsic properties and core advantages |
| Abrasion resistance |
Intrinsic properties: Hardness is second only to diamond and silicon carbide. Advantages: It is the ultimate material for resisting abrasive wear, and its lifespan in media containing solid particles far exceeds that of metals, greatly reducing downtime for maintenance. |
| Corrosion resistance |
Intrinsic properties:It exhibits extremely high chemical inertness to strong acids, strong alkalis, organic solvents, and salts. Advantages: It fundamentally solves the problem of sealing failure caused by media corrosion in the chemical and pharmaceutical industries. |
| High temperature resistance |
Intrinsic properties:It has a high melting point and excellent strength and hardness retention at high temperatures. Advantages: It can operate stably in high-temperature environments where the metal sealing ring has softened and failed, thus broadening the upper limit of its application temperature. |
| High stiffness and dimensional stability |
Intrinsic properties:High elastic modulus ensures rigidity, and low coefficient of thermal expansion ensures dimensional stability. Advantages: Under pressure and temperature fluctuations, the sealing surface deforms minimally, maintaining a tight fit, which is fundamental to achieving long-lasting seals. |
| Cleanliness and bioinertness |
Intrinsic properties:Made of pure, non-adhesive material, it is not prone to microbial growth and can withstand high-temperature sterilization. Advantages: Meets the stringent hygiene requirements for sterility and pollution-free conditions in industries such as pharmaceuticals, food, and bioengineering. |
| Low density |
Intrinsic properties:Its density is significantly lower than that of metals (such as steel). Advantages: It reduces the centrifugal force of high-speed rotating parts, improves dynamic balance, and is conducive to achieving high speed and high response in equipment |
Application
| Applications | Core role |
| 1. Chemical and process industries (pumps, reactors, valves for conveying acids, alkalis, salts, slurries, and solvents) | Achieving reliable sealing under conditions of high corrosion, high wear, and high temperature prevents leakage of harmful media and ensures safe and continuous production. |
| 2. Oil and Gas (Multiphase Flow Pumps, Downhole Tools, Pipeline Booster Pumps) | Achieving long-lasting seals in harsh environments containing sand, high pressure, and corrosive substances, and withstand extreme erosion and pressure. |
| 3. Pharmaceutical and Bioengineering (Fermenters, Centrifuges, Aseptic Transfer Pumps) | Achieving high cleanliness and sterile sealing, withstands repeated high-temperature steam sterilization and chemical cleaning, and prevents product contamination. |
| 4. Electricity and Energy (Boiler Feed Pumps, Nuclear Power Plant Auxiliary Pumps, Desulfurization Circulation Pumps) | Provide stable sealing in environments such as high-temperature and high-pressure hot water and water treatment chemicals, ensuring long-term system operation. |
| 5. Automotive and Transportation (Heavy-duty vehicle cooling pumps, new energy vehicle cooling systems, fuel cell systems) | Improve the sealing reliability of coolant and medium over a wide temperature range and long cycle, adapting to more demanding operating conditions. |
| 6. Aerospace and specialized fields (rocket engine turbopumps, satellite propulsion systems) | Achieving ultra-high reliability of "zero leakage" seals in extreme temperatures, vacuum, and special propellants. |
| 7. Suitable for harsh industrial applications (high-temperature fans, scrubbing towers, papermaking, metallurgy, etc.) | Replace traditional seals, solves the problem of frequent failures under harsh conditions, and significantly extends the maintenance cycle. |
