Zirconia ceramic lower cover lining

Zirconia ceramic lower cover lining: high-performance sealing and wear-resistant solution

User’s question: My device’s lower cover seal is prone to wear and has poor corrosion resistance, resulting in frequent shutdowns for replacement and affecting production efficiency. What should I do?
Answer: Zirconia ceramic lower cover liner provides you with a super wear-resistant, high-temperature resistant, and corrosion-resistant sealing solution, significantly extending component life and reducing maintenance costs.
User question: Traditional metal lining is prone to deformation in high temperature and high pressure environments, leading to seal failure. How can this be resolved?
Answer: Zirconia ceramics have extremely high hardness and stability, maintaining shape and performance under extreme working conditions, and eliminating leakage problems caused by deformation.
User asked: I need to customize a special size lining, but standard products on the market cannot match. What are my options?
Answer: We provide full-size customization services, from micro precision components to large industrial components, all of which can be designed and manufactured according to your needs, perfectly adapting to your equipment.

The inner lining of the zirconia ceramic lower cover is made of high-purity zirconia (ZrO ₂) material, which is produced through advanced molding and sintering processes. It is a sealing and protective component designed specifically for high wear, strong corrosion, and high temperature and high pressure environments. Widely used in fields such as pump valves, mechanical seals, chemical equipment, medical devices, etc.

Product advantages

1. Excellent wear resistance
   Zirconia ceramics have a hardness of HRA88 or higher, and their wear resistance is more than 10 times that of traditional metal materials, greatly extending the service life of equipment.
2. Excellent corrosion resistance
   Resistant to corrosion from chemical media such as acids, alkalis, and solvents, suitable for corrosive environments such as chemical, electroplating, and pharmaceutical industries.
3. High temperature stability
   It can withstand temperatures above 800 ℃, has a low coefficient of thermal expansion, maintains dimensional stability in high temperature environments, and avoids thermal stress failure.
4. High strength and toughness
   Through phase transformation toughening technology, the fracture toughness is superior to ordinary ceramics, and the impact resistance is significantly improved.
5. Precision machining capability
   The surface smoothness can reach Ra0.2 μ m, with a dimensional accuracy of ± 0.01mm, ensuring a tight fit of the sealing surface.
