AI Technical Summary

Problems solved by technology

Due to the characteristics of ceramic fiber materials, the fiber filaments are brittle and easily entangled. The commonly used tunnel furnace is used for sintering. The fiber material needs a carrier. It is difficult to guarantee the stability and consistency of the product during the sintering process of the fiber material.

Therefore, the quality of ceramic fiber materials is average at present, and it is difficult to produce high-quality high-alumina ceramic fiber materials with good performance.

The existing ceramic fiber material preparation equipment usually adopts the method of tunnel furnace propulsion, but in the production process, the fiber material is supported by the existing carrier, the fiber filaments are easily entangled and broken during the sintering process, and the layers of the sintered fiber material are heated unevenly, making it difficult to reach different positions The consistency of the mechanical properties of the wire will greatly affect the performance and comprehensive performance of the ceramic fiber material

Disadvantages of the existing technology: most of the existing ceramic fiber material products are continuously produced by tunnel furnaces. During the sintering process, the fiber threads are wound on the object in multiple layers and then sintered. It is difficult to ensure the consistency of the products in this way.
