Ceramic Screw For Screw Pump Of Silicon Carbide/Zirconia To Transimitt Mud Or Syrup
Description of ceramic screw:
Our new products, which are used in screw pump. Because of the structural and material advantages, the ceramic screw pump can be used to transport the liquid with high viscosity, such like powder, syrup and mud etcs. Because of its high strength and low thermal expansion, pressureless sintered silicon carbide (SSiC) is one of the best material for the pumps.
►Key properties of pressureless sintered silicon carbide |
♦ Max Temperature up to 1650℃ |
♦ Low density:3.15-3.18 g/cm3 |
♦ High strength |
♦ Low thermal expansion : 4.0 (10-6/℃) |
♦ High thermal conductivity:120 W/m°K |
♦ High hardness:2800 HV5 |
♦ High elastic modulus: 410GPa |
♦ Superior chemical stability,resistance to acid and alkali corrosion (incld. hydrofluoric acid) |
►Key properties of zirconia |
♦ Max Temperature up to 380℃ |
♦ High density: 6.09 g/cm3 |
♦ Low thermal conductivity |
♦ Chemical stability, resistance to acid and alkali corrosion |
♦ High fracture toughness KIC:8-11 MPa-m1/2 |
♦ Good electric insulation |
♦ Better bearing capacity |
♦ Wear resistance |
♦ High hardness : 1300 HV5 |
