Here are different types of ceramic fiber wool for you to choose from. They have different chemical indicators and performance properties. Kerui ceramic fiber cotton is made of high-purity silicon and aluminum raw materials using spinning or blowing processes. In addition, in the vacuum forming process, ceramic bulk fiber is the basis for ceramic fiber blankets, boards, papers and other products. No matter which ceramic fiber wool you choose, they all offer excellent performance.
The following data comes from multiple tests in Kerui laboratory and the best combination derived from market feedback. If you have additional needs, please contact Kerui and we will provide customized solutions.

In order to achieve different product properties, Kerui mainly uses two manufacturing processes: spray (also called spinning) and wire throwing. Both of these two manufacturing process brings excellent performance. They come into different features and applications. Please keep reading to know which manufacturing process is more suitable to you:
Spray ceramic fiber insulation bulk does not contain binders and has low slag ball content. From a technical perspective, the spray ceramic fiber cotton has a smaller diameter usually at 2.0-4.0 μm and a longer length about 100-200 mm. Due to its excellent structure and lower thermal conductivity, it can achieve good thermal insulation effect. In addition, spinning ceramic fiber cotton is more suitable as a raw material for ceramic fiber blankets or modules. Besides, this high quality ceramic fiber insulation material is also easy to shred or cut into required shapes.
Kerui wire throwing ceramic fiber cotton comes with double-sided needle punching process. Therefore, it forms a tough and high-rebound structure. The throwing ceramic fiber bulk has a diameter of 3.0-5.0 μm and a length of about 150-250 mm. Using the throwing process, ceramic fiber wool can form a tight thermal insulation layer. This product has good tensile strength and is durable. This twisted ceramic fiber wool is often added to ceramic fiber cloth, belts, ropes to enhance toughness. In addition, the product exhibits excellent tear resistance both before and after heating.
Kerui ceramic bulk fiber is an excellent thermal and insulation material. Using large ceramic fiber wool as the insulation layer of industrial kilns can not only reduce the difficulty of construction, but also greatly improve the insulation effect. The lower thermal conductivity can effectively improve overall energy utilization.
The furnace and furnace lining are important parts of the industrial furnace. In complex working environments such as high temperatures and chemical erosion, ceramic fiber wool maintains a good structure with its excellent performance. Use this product in industrial kiln linings to resist high temperatures and chemical corrosion.
High-temperature industrial furnaces involve many corners, door gaps, furnace lids and other complex parts, which are also the main areas for heat loss. At this time, the good refractory ceramic fiber wool has a good sealing effect with its flexible shape. Customers can use high-quality ceramic fiber wool to avoid energy loss.
In a long-term high-temperature working environment, industrial kilns will inevitably suffer from wear, damage and other problems. Kerui ceramic fiber wool is suitable for repairing furnace bodies and can quickly protect the stable operation of the furnace. This product has excellent performance and can extend the service life of the kiln.
