Hardness and Wear Resistance: Zirconia ceramics have a hardness of HRA 88 or higher, a Mohs hardness of 9.0-9.5 (second only to diamond), and a Vickers hardness of HV 1200-1500. Their wear resistance is 3-5 times higher than that of metals.
Mechanical Strength: Bending strength reaches 750-1200 MPa, and fracture toughness reaches 6-15 MPa·m¹/².
Environmental Stability: High temperature resistance up to 1000℃ (working temperature can reach 2400℃), resistance to acid and alkali corrosion, and a low coefficient of thermal expansion (10-11×10⁻⁶/°C)
Introduction to Zirconia Ceramic Calender Rolls:
Zirconia ceramic calender rolls are high-precision industrial components manufactured from zirconia (ZrO₂) ceramic material, primarily used in mechanical processing and electronics manufacturing. Their core characteristics include excellent properties such as high temperature resistance, wear resistance, and corrosion resistance. In specific applications, these rolls are commonly found in offset printing presses, flexographic printing presses, and gravure printing presses, where they serve as critical transmission or calendering components.
