In the industrial areas of petrochemical, chemical fiber, fertilizer, atomic energy, aerospace and machinery manufacturing,
The higher requirement for mechanical seal should be able to operate under high speed, high pressure, high temperature,
low temperature, strong corrosion and solid particles.
Zirconia is a material with superior performance in inorganic non-metallic materials. It is resistant to corrosion, high temperature
and wear resistance, and is known for its strong strength and toughness.It makes mechanical seal ring, which can prolong the
life of the sealing ring, reduce the number of change, reduce the cost and improve the efficiency.
Features of zirconia ceramic sealing ring:
1. High hardness, good wear resistance, small thermal conductivity, good chemical stability and high corrosion resistance.
2. High fire resistance.Can withstand temperatures up to 1500 ℃
3. Good chemical stability. It can resist acid corrosion at high temperature.
4. Strong strength, abrasion resistance, good chemical stability, good biocompatibility and high density.
5. It is a kind of inorganic non-metallic material with high temperature, abrasion resistance and corrosion resistance. It is one
of the best refractory materials in nature.
The products are made of high purity Zirconia ceramics (Zro₂) and Alumina Ceramics (Al₂O₃) material, which have
advanced and excellent performances, fabulously popular .
