Brief Introduction of Ceramic Fiber Product
Main raw material of Kerui ceramic fiber insulation products is high-purity calcium silicate strict. Kerui produces them high-temperature melting and fiber making processes. The ceramic fiber is white and odorless. It has good toughness, so it can achieve better insulation effect and apply in a wider range of industries. To meet different kinds and requirements in various situations, Kerui offers a wide range of ceramic fiber products.
Alternative names for Kerui ceramic fiber products are ceramic fiber textile products, high temperature ceramics, calcium silicate products, calcium silicate fire resistant products and so on.
Manufacturing Process of Ceramic Fiber Product
Preparation of Raw Materials
The process begins with the preparation of raw materials. The main components are alumina and silica, which are typically derived from minerals such as aluminium bauxite and quartz. These raw materials undergo crushing, grinding and mixing to achieve the desired chemical composition and consistency. Moreover, customers may require other additives to improve the overall performance of these ceramic fiber linings. The raw materials determin the final property of refractory ceramic fiber products.
Form of Ceramic Fiber
After preparing the raw materials, employees will process them to ceramic fiber. There are two common methods for forming ceramic fibers:
- Spinning: it melts the raw materials at high temperatures and then spun into fine fibers using centrifugal force or air blowing techniques. Workers need to collect the fibers to form a fibrous mat.
- Blowing: in the blowing process, the molten raw materials will force through spinnerets or nozzles, where cool them by air or gas streams.
Mold Ceramic Fiber Products
When it comes to the molding system, it will form ceramic fibers depending on the desired application. Some common forms of ceramic fiber products include blankets, boards, modules, papers, cloths, ropes, tubes and wool. Then it comes to compressing, layer or weaving of ceramic fiber products to achieve the desired thickness, density and shape. Kerui adopts precise molding technology to meet your requirements. Importantly, we support customized shapes of all kinds of ceramic insulation products for sale.
Package and Delivery
After molding ceramic fiber products, Kerui will conduct strict quality control to ensure these products meet the specifications and standards. After passing the quality control checks, Kerui employees will pack the ceramic fiber products for delivery. Packaging methods may vary depending on the product form and customer requirements. Then Kerui workers will ship these products to their intended destinations and ready for use in various applications.
