Description of Ceramic Fiber Board

Ceramic fiber board is a kind of refractory material, usually composed of alumina and silicate, and it is also called an aluminum silicate board. Ceramic fiber board is made of ceramic fiber cotton, natural refractory raw materials, and a small amount of organic binder as the main raw materials, and is processed by a fully automated control continuous production line. After heating, it has very good mechanical properties and has a certain hardness support, which provides a strong guarantee for the kiln to save energy and reduce consumption, high quality, and high output.

Advantages of Ceramic Fiber Board

Lightweight

Ceramic fiberboard has low density, easy to handle, and has high strength. This makes it easier and more flexible in various applications and reduces the load on the structure. Kerui Refractory will provide you with the highest quality ceramic fiber boards.

Evenly Heated

Uniform fiber distribution ensures evenly surface heating temperature and reduces thermal strain. This helps avoid cracking and deformation caused by temperature differences, improving product stability and durability.

Good Toughness

Ceramic fiberboard has a certain tensile capacity and is not easy to break. This enables resistance to impact and mechanical stress during use, enhancing the durability of the product. Welcome to visit Kerui Factory.

High Compressive Strength

It can withstand a certain amount of pressure and maintain structural integrity and stability. Ceramic fiber board ensures the reliability and safety of the product during use. It has a long service life.

Manufacturing process of Ceramic Fiber Board

1. Raw material Preparation

First prepare high-purity ceramic fibers as the main raw materials, such as alumina fibers and aluminum silicate fibers, which are usually in the form of rolls or felts. Kerui will choose the best quality raw materials for customers.

2. Preparation of Additives

Additional additives, such as slurry thickeners and binders, can enhance the fluidity of fiber slurry. Then the ceramic fiber is mixed with an appropriate amount of water to form a fiber slurry. The additives depends on the user’s requirements.

3. Stir Evenly

After the raw materials and other additives are prepared, put them together and use a mixer to stir and disperse them to ensure that the fibers are evenly distributed and avoid clumping. Ensure stable product quality.

4. Forming

The vacuum principle is used to suck the stirred fiber slurry into the mold, and the fiber slurry is formed into the size required by the user through pressing. Bubbles will be eliminated during this process to ensure a smooth surface.

5. Solidification

The formed fiberboard can be placed in a constant temperature environment and wait for it to solidify, so that the water will gradually evaporate, and the fiberboard will gradually solidify. You can see the prototype of the product.

6. Drying

The fiberboard should be heat treated in the drying equipment, the temperature is usually between 200°C and 400°C, and the drying time should be controlled to remove residual moisture and improve the stability of the fiberboard.

7. Processing and Correction

After drying, the fiberboard may have some unevenness, so it is necessary to use cutting, and grinding technology to cut the product into the required size. Ultimately providing customers with the best quality products.
