Zirconia Ceramic hierarchical wheel used for for classifying equipments
Description:
Classification wheel usually has two kinds of metal and ceramic, for some materials sensitive to magnetic pollution must use ceramic classification wheel, and in the current market, most choose zirconia ceramic classification wheel.
Zirconia Ceramic hierarchical wheel have the advantages of super hardness, high wear-resisting, good corrosion resistance, high temperature tolerance, high strength, high mechanical strength, good chemical stability, polishing surface and so on.
Principal characteristic :
1. High density.
2. High fracture toughness .
3. High hardness High Mechanical Strength.
4. Low thermal conductivity Excellent insulation .
5. Good Wear resistance.
6. Resistant to Corrosion and Chemical Attack.
7. Extreme Temperature Stability.
8. Outstanding Electrical and Electronic Properties.
Application of Zirconia Tube Oxygen Sensor Size Customized Structural Ceramic Components:
Ultrafine grinding equipment, fine chemical industry, electronic paste, semiconductor, new energy, nano new materials, medical instruments, precision casting, structural ceramics, refractory materials, electronic communications, sensitive ceramics, petrochemical industry, aerospace, machinery manufacturing, optical fiber connector, battery materials and other high-precision end fields.
