Advantages of ceramic insulators in heaters

  • Insulating material: Ceramic insulators are mainly used in heaters to isolate current and ensure the safety of the whole device. Due to its good insulating properties, ceramics can be used as an insulating material for electrically heated devices, preventing current leakage and improving the service life and safety of the entire device.
  • Heating material: In addition to being used as an insulating material, ceramics can also be used as a heating material to generate heat by means of resistance heating. The preparation technology of ceramic heating element is relatively simple, and it has good stability under high temperature conditions, and can maintain stable electrical properties, so as to achieve the effect of rapid heating and efficient heating.

Specific application examples of ceramic insulators in heaters

  • Electric heaters: Electric heaters are one of the most typical applications of ceramics in the field of electric heating. Due to its good insulation properties and high temperature stability, ceramics can be used as insulating materials and heating materials for electric heating devices, making electric heating devices have more stable and safe performance .
  • Electric heater: Electric heater is a common small electric heating device, because ceramics can still maintain stable performance at high temperatures, so it is widely used in the heating element of electric heaters, so that the electric heater has the characteristics of rapid heating and efficient heating .
  • Injection Molding Machines and Extruders: Ceramic belt heaters are suitable for heating the plasticizing cylinders, bushings and nozzles of injection molding machines as well as the screw barrels of extruders. These applications require high-temperature and stable heating solutions, and ceramic belt heaters offer excellent thermal conductivity and high temperature resistance.
