Alumina Seal Ceramic Rings / Industry Insulation Rings
1. Description:
Alumina ceramic heating element vs PTC ceramic heating element
The component heats the air directly: MCH has better air heating effect than PTC.
Electric heater heating air: The air heating effect of MCH electric heater is better than that of PTC electric heater. At low heat level, the maximum temperature of MCH can reach 115℃, while PTC is only 93℃. In the high-heat mode, the balanced power of MCH is only about 80% of PTC.
2. Feature Advantages:
1) Refractory, High Temperature Resistance, Maximum Used
Temperature: 1800 ºC (3272ºF)
2) Hardness Strength, Wear Resistance Up To Mohz 9.0 ; HRA 80-90
3) High Voltage, Good Insulation Performance ,Electrical
Resistivity Up To 10∧14 Ohm.Cm
4) High Polished Surface Up To Rz0.8(Ra0.1)
5) Superior Mechanical Strength, MAX 10 MPa.m1/2 Fracture toughness
6) Pressure Resistance, Max 2300MPa compressive strength
7) Anti-High Corrosion Resistance, Such As Acid Alkali Resistance
8) Long Service Life
9) Other excellent property
