Ceramic fiber paper is a high-performance insulation material made from ceramic fibers. Due to its thin and lightweight nature, it is referred to as “paper.” It is known for its excellent high-temperature resistance, corrosion resistance, and superior thermal insulation properties. Primarily used in industrial applications, this article provides a brief introduction to the parameters, characteristics, and applications of ceramic fiber paper.

 

 

 

Parameter Overview

  • Thickness: 0.4-10 mm
  • Density: 260-320 kg/m³
  • Operating Temperature: Up to 1200°C

 

 

Key Features

1. High-Temperature Resistance

Ceramic fiber paper can withstand temperatures up to 1200°C, making it suitable for various high-temperature environments. Its exceptional thermal stability ensures reliable performance under extreme heat conditions.

2. Excellent Thermal Insulation

With a low thermal conductivity, ceramic fiber paper effectively reduces heat transfer and loss, providing outstanding insulation properties.

3. Electrical Insulation

Composed primarily of inorganic materials, ceramic fiber paper offers excellent electrical insulation, making it ideal for applications requiring non-conductive properties.

4. Corrosion Resistance

Ceramic fiber paper exhibits stable chemical properties, enabling it to resist both acidic and alkaline substances effectively. This makes it highly durable in corrosive environments.

 

 

Manufacturing Process

Ceramic fiber paper is produced using high-quality ceramic fiber cotton with low slag ball content. The manufacturing process involves several steps:

  1. Pulping: Breaking down the ceramic fibers into a slurry.
  2. Deburring: Removing impurities and slag balls.
  3. Slurry Mixing: Preparing the fiber mixture.
  4. Forming: Using a long-net forming machine to shape the paper.
  5. Vacuum Dehydration: Removing excess water.
  6. Drying: Ensuring the paper is completely dry.
  7. Cutting and Rolling: Finalizing the product into usable sheets or rolls.

 

 

Applications

Ceramic fiber paper is widely used in various industrial and commercial applications due to its versatile properties. Some common uses include:

1. Thermal Short-Circuit Prevention

Used to prevent heat loss and improve energy efficiency in high-temperature equipment.

2. Insulation Sealing Gaskets

Provides effective sealing and insulation in high-temperature environments.

3. Expansion Joints
