Benefits of Using Ceramic Fiber Paper

Energy Saving

Kerui ceramic fiber paper has low thermal conductivity and low heat storage, which means it can reduce heat loss and save energy. It can also resist thermal shock and withstand temperature fluctuations without cracking or degrading. Ceramic fiber paper combined with refractory brick liner can help improve the efficiency and performance of furnaces, kilns, ovens, boilers and other heating equipment.

Easy Construction

The ceramic fiber insulation paper is lightweight, flexible and easy to cut and shape. It can be molded, wrapped or layered to fit different geometries and surfaces. Besides, this product can be bonded with adhesives, staples or pins to secure it in place. Kerui ceramic fiber paper can be used as insulation, gaskets, seals, liners and fire protection in various industries and applications.

Safe Operation

One of the most important factors in choosing this product is fire-resistant and can withstand temperatures up to 2300°F. It does not melt, burn, or emit toxic fumes when exposed to fire. It also has good dielectric strength and can resist electrical breakdown. The insulation paper can provide protection from fire hazards and electrical shocks in various environments.

Additional Benefits

As a kind of superior product for high-temperature applications, Kerui insulation products has many additional benefits. It has excellent corrosion resistance and can resist most chemicals except hydrofluoric, phosphoric acids and concentrated alkalis. It also has good sound absorption and can reduce noise and vibration. This product can enhance the quality and durability in where requires high-temperature insulation and protection.

Manufacturing Process of Ceramic Fiber Paper

Ceramic fiber paper is a unique product that primarily consists of an aluminum silicate fabric in a non-woven matrix with a latex binder system. If you want to watch more videos about Kerui ceramic fiber products, please follow Kerui Youtube. The manufacturing process of ceramic fiber products involves several key steps:

1. Raw Material

The first step in the production process involves the purification and dispersion of refractory fiber. This ensures that the ceramic fiber used in the production comes with high quality and free from impurities.

2. Pulping

The purified and dispersed refractory fibers then come to pulping stage. This process involves breaking down the fibers into a pulp, which forms the base material for the ceramic fiber paper.

3. Paper Forming

After pulping, it comes to paper forming process. This is done using a specialized paper-making process to form uniform, lightweight, flexible sheets. This step is crucial in determining its quality.

4. Drying

After the paper has been formed, it undergoes a process of dehydration and drying. This involves removing any excess water from the paper and then drying it to ensure it is completely dry.

5. Burning off Binder

The final step in the production process is burning off the binder. This is done to remove any remaining binder from the paper and to ensure that the final product is pure refractory fiber paper.

Uses of Kerui Ceramic Fiber Paper

  • Industrial insulation, sealing and anti-corrosion materials;
  • Electric heating device insulation and insulation materials;
  • Insulation and thermal insulation materials for instruments, equipment and electric heating elements;
  • Expansion joint filling material;
  • Isolation materials for building materials, metallurgy, glass and other industries;

Tips about Using Ceramic Fiber Paper

Protect the Sealing Surface

Do not damage the sealing surface or sealing line of the ceramic insulation paper. The flat sealing performance relies on the two end surfaces. There should be special protection during handling, installation and storage. Once damaged, it often results in a difficult-to-use effect.

Avoid Forceful Installation

Do not forcefully install the ceramic paper insulation products. Construction should not be rough or brutal. Forceful installation with large movements will inevitably destroy the original prefabricated structure. This type of installation must be very careful and meticulous and embedding must be carried out step by step.

Balance and Symmetry in Installation

Customers and workers should emphasize balance and symmetry, especially during installation. After the system is put into use, further observation and post-tightening work need to be done to prevent unnecessary trouble during the system operation.
