Introduction to the production process of insulating ceramic sheets

Introduction to the production process of insulating ceramic sheets

Insulating ceramic sheets are mainly used in industry. Pintejin Ceramics is a zirconia ceramics manufacturer specializing in the production and machining. The following is an introduction to the production process of insulating ceramic sheets by Pintejin Ceramics. Insulating ceramic sheet Insulating ceramic sheet is an industrial ceramic part. The specific process flow chart is as follows:

Ingredients – Mixing and grinding – Pre-firing – Secondary grinding – Granulation – Forming – Plastic removal – Sintering into porcelain – Shape machining – Electrode – High voltage polarization – Aging test.

  • 1. Ingredients: carry out pre-machining of materials, remove impurities and moisture, and then weigh various raw materials according to the proportion of the formula. Note that a small amount of additives should be placed in the middle of the aniseed.
  • 2. Mixing and grinding: The purpose is to mix and grind various raw materials to prepare conditions for complete solid-phase reaction for pre-sintering. Generally, dry grinding or wet grinding is used. Dry grinding can be used for small batches, and stirring ball milling or jet pulverization can be used for large batches, which is more efficient.
  • 3. Pre-sintering: The purpose is to conduct solid-phase reaction of each raw material at high temperature to synthesize piezoelectric ceramics. This process is very important. It will directly affect the sintering conditions and the performance of the final insulating ceramic sheet.
  • 4. Secondary fine grinding: The purpose is to finely vibrate and mix the pre-fired ceramic powder, so as to lay a solid foundation for the uniform performance of the porcelain.
  • 5. Granulation: The purpose is to make the powder form high-density granules with good fluidity.
  • 6. Forming: The purpose is to press the pelletized material into the required prefabricated size blank. Alumina ceramic insulating sheet
  • 7. Plastic removal: The purpose is to remove the binder added during granulation from the blank.
  • 8. Sintering into porcelain: The blank is sealed and sintered into porcelain at high temperature. This part is very important.
  • 9. Shape machining: Grind the fired product to the required finished product size.
  • 10. Electrode: Set conductive electrodes on the required ceramic surface. The general methods are infiltration of silver layer, chemical deposition and vacuum coating.
  • 11. High-voltage polarization: orient the internal electrical domains of the ceramics, so that the ceramics have insulating properties.
  • 12. Aging test: After the performance of the insulating ceramic sheet is stable, test various indicators to see if it meets the expected performance requirements.
