In high-temperature industrial production, ceramic fiber cloth used in high-temperature conveyor belts must withstand both high-temperature baking and material friction. Insufficient wear resistance can lead to frequent replacements, increasing production costs. To address this issue, multiple wear-resistant improvement technologies can significantly extend the service life of ceramic fiber cloth, ensuring the stable operation of high-temperature conveyor belts.
Optimizing fiber material composition is the core foundation of wear-resistant improvements. Traditional ceramic fiber cloth is made from single-fiber aluminum silicate fibers, which are prone to fiber breakage and shedding under prolonged friction. The improved technology achieves enhanced performance through composite fiber blending, incorporating 10%-15% high-strength aluminum oxide fibers into the ceramic fibers. This leverages their higher tensile strength to enhance overall wear resistance. Experimental data shows that the wear resistance of composite fiber ceramic fiber cloth can reach 2.3 times that of single-fiber products, with a wear rate reduction of over 60% at 800°C. Additionally, fibers with more uniform diameters (with an error control of within 0.5μm) are selected to reduce localized wear caused by uneven fiber thickness.

Improved weaving structure effectively distributes friction stress. The ceramic fiber cloth for high-temperature conveyor belts adopts a “multi-layer interlacing + densified weaving” process, changing the traditional plain weave to a twill or satin weave to increase the density of fiber interlacing points. The outer layer uses a 3/1 twill structure to enhance surface smoothness and reduce friction resistance; the middle layer employs a densified satin structure to strengthen overall tear resistance. Comparative tests show that the improved weaving structure of the ceramic fiber fabric extends its service life by 1.8 times under the same friction conditions, with a significant reduction in surface pilling. For high-wear areas such as conveyor belt edges, a double-layer thickened weaving is adopted, increasing local fiber density by 50% to form a wear-resistant protective band.
Surface reinforcement treatment is a key method for enhancing wear resistance. Through a high-temperature impregnation process, a silica wear-resistant coating is formed on the surface of the ceramic fiber fabric, with a coating thickness controlled between 5-10μm. This does not affect flexibility while forming a hard protective layer. After treatment, the surface hardness of the ceramic fiber fabric increases by 40%, and the coating is tightly bonded to the fibers, making it unlikely to peel off even under repeated friction. Another improved technology involves the use of glass fiber mesh fabric for composite reinforcement. The ceramic fiber fabric is bonded with high-temperature-resistant mesh fabric using a high-temperature adhesive. The mesh structure disperses friction stress, enhancing the ceramic fiber fabric’s wear resistance by over 30% while maintaining excellent high-temperature resistance.
Optimized edge sealing process reduces localized wear. The edges of high-temperature conveyor belt-specific ceramic fiber cloth are treated with “edge wrapping + hot pressing.” High-strength ceramic fiber threads are used for edge stitching, with stitch density increased to 5 stitches per centimeter, followed by hot pressing at 200°C to prevent edge fiber loosening and fuzzing. Practical applications show that the edge wear rate of the improved ceramic fiber cloth is reduced by 70%, effectively preventing overall tearing caused by edge damage.
Through comprehensive improvements in material, structure, surface, and process, the wear resistance of the high-temperature conveyor belt-specific ceramic fiber cloth has been significantly enhanced, providing a more durable protective solution for high-temperature material conveyance.
