characteristics and applications of polycrystalline ceramic fiber boards

  1.High - temperature Resistance

      1.It can withstand high - temperature environments ranging from 1000°C to 1750°C and maintain stable performance in extremely high - temperature conditions.

  2.Low Thermal Conductivity

      1.Its thermal conductivity is much lower than that of traditional refractory materials (such as refractory bricks, cast stones, etc.). It can effectively reduce heat transfer, thereby reducing heat loss, improving energy efficiency and reducing energy consumption.

  3.Lightweight and Easy to Process

      1.It has a relatively low density and is lightweight. This makes it convenient during transportation, installation and use. The installation is efficient and the transportation cost is low.

  4.Good Chemical Stability

      1.It has strong corrosion resistance to most acids, alkalis, salts and organic solvents, and can maintain its performance in a chemical environment, thus prolonging its service life.

  5.Excellent Mechanical Strength

      1.It has relatively good mechanical strength, can withstand a certain amount of external pressure, and has good toughness and wear resistance, which can prevent surface damage or deterioration.

II. Applications

  1.High - temperature Furnaces and Heating Equipment

      1.As a common heat - insulating material, it can effectively reduce the heat loss in the furnace, keep the temperature stable and reduce energy consumption.

  2.Petroleum and Chemical Industries

      1.It is widely used for high - temperature insulation of pipelines and equipment. It can reduce energy consumption, improve the operating efficiency of equipment, and can also resist harsh chemical environments.

  3.Aerospace and Aviation Fields

      1.It is an important material for the thermal protection systems of spacecraft and aircraft, used for thermal protection shields and engine insulation layers, meeting strict heat - insulation requirements.

  4.Ceramics and Glass Manufacturing Industries

      1.It is widely used in the heat - insulation and heat preservation of melting furnaces, annealing furnaces and drying equipment, ensuring the temperature stability during the production process and reducing energy waste.
