Alumina ceramic plungers and wear-resistant precision bearing rods are high-performance ceramic components used in industrial applications, possessing the following core characteristics and applications:
Core Characteristics
1. Superior Wear Resistance: 99% alumina ceramic plungers have a Mohs hardness of 9, and their wear resistance is 10-20 times that of stainless steel, making them suitable for high-wear environments. Mirror polishing technology can reduce the friction coefficient and achieve a self-lubricating effect.
2. High Temperature Resistance and Stability: With a melting point of up to 2075℃ and a thermal expansion coefficient only 1/3 that of metals, they can operate stably at temperatures up to 1700℃, making them suitable for extreme operating conditions.
3. Precision Machining Capability: Processed to a mirror finish using high-precision internal and external cylindrical grinding machines, the surface roughness can be controlled to Ra≤0.02μm, meeting the precision requirements of medical, semiconductor, and other fields.
Application Fields
1. Petrochemical Industry: Used in oilfield fracturing pumps, reducing annual maintenance costs by 70%, and is the preferred choice for operating pressures >50MPa.
2. Medical Equipment: Used in precision drug delivery systems such as insulin pumps, with an error as low as 0.1μL.
3. New Energy: Used in lithium battery coating machines to transport high-viscosity slurries, with a pulsation amplitude of <1%.
4. Environmental Engineering: Wastewater treatment pumps can stably handle particle-containing fluids, increasing efficiency by 40%.
